Lisfranc injuries are rare but severe injuries of the foot. They range from ligament sprain to complex fracture dislocations. Etiologically, a distinction is made between indirect and direct force and between high-energy and low-energy trauma. Inadequate diagnostics (injuries overlooked or misinterpreted) can lead to painful posttraumatic osteoarthritis, chronic instability and deformity of the foot. A fracture, malalignment and unclear findings in conventional radiological diagnostics necessitate computed tomography imaging including 3D reconstruction. Lisfranc injuries are often associated with accompanying pathologies of the foot that also need to be addressed. Only stable non-displaced fractures can be treated conservatively. Depending on the injury pattern, surgical treatment is performed percutaneously, minimally invasive or open. The prognosis following Lisfranc injury is determined by the severity of damage and the quality of reconstruction., (© 2024.

Urgent consultations for foot injuries are common. Trauma injuries are often obvious, such as displaced or open fractures, dislocations, or tissue breakdown. However, they can also have a subtle presentation and still hide severe structural damage. This is the case of «benign» Lisfranc sprains, compartment syndrome or even tendon sections through an apparently benign wound. The purpose of this article is to help the primary care physician to be aware of these subtle and sometimes hidden injuries, to assist him in the diagnosis and to provide the keys to appropriate treatment., Competing Interests: Les auteurs n’ont déclaré aucun conflit d’intérêts en relation avec cet article.

Pediatric ankle and foot injuries are common complaints in the emergency department, and proper identification and management of these injuries is critical for uninterrupted limb development. This issue reviews the presentation, systematic evaluation, and management of common pediatric orthopedic injuries of the ankle and foot. Recommendations are given for the disposition of pediatric patients with ankle and foot injuries, with a focus on which patients need immediate orthopedic evaluation and which patients can be discharged home with appropriate follow-up.

Deep feet frostbite is a severe trauma and often leads to amputation due to full-thickness skin necrosis and subcutaneous tissue damage. A retrospective analysis was performed between June 2013 and June 2019 to review the management measures and outcomes of clinical treatment, and available data had been collected including demographic characteristics, risk factors, and injury environment record. Treatment protocols, wound management, and outcomes were also presented. There were 36 patients diagnosed with deep feet frostbite with a mean age of 51.5 years; the ratio for male to female is 5:1. Drunk and mental disorders were the main risk behaviors for frostbite occurrence. As for the injury environment, mean temperature and wind speed were -20.5 °C and 3.3 m/s, respectively. Fourteen cases achieved wound healing without surgery intervention, 5 cases received skin graft, and 17 cases received amputation. Most amputations (12 cases) were restricted at toe level; only 1 case received whole feet amputation. Our finding indicated that feet deep frostbite in our hospital showed a male predominant and older age including various risk behaviors and coexistence risk factors. Clinical management based on pathology mechanism needs further improvement, as the amputation rate was still high. How to avoid amputation and lower the amputation level are the focus of future efforts.

Recreational sports are more popular, with many athletes involved year-round in multiple sports and on multiple teams. Most athletes do not take proper rest, making them more susceptible to stress-related injuries. There are numerous sports-related injuries in the foot and ankle. These issues can be non-traumatic, due to chronic repetitive stresses, or traumatic. Most of these injuries are managed conservatively, and athletes do well and return to play, while some do better with operative management. This article discusses a few of the sports injuries that are common in the leg, foot, and ankle and the recovery process., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel respiratory virus that has rapidly changed the practice of medicine. The authors sought to evaluate the clinical presentation and clinical outcomes of patients presenting with foot and ankle (F&A) trauma to the emergency department during the first wave of the pandemic. The authors retrospectively studied all patients who presented to an emergency department within their multicenter institution during the first wave of the pandemic in their region from March 1 to June 30, 2020, with F&A trauma. They compared this cohort with a matched control group of patients who presented the prior year. Demographics, perioperative factors, coronavirus disease 2019 (COVID-19) polymerase chain reaction testing/positivity rates, 30-day readmissions, and 30-day mortalities were collected and analyzed. During the pandemic, the authors saw a 62.0% decrease in the total number of patients presenting with F&A trauma. Patients who presented during the pandemic were significantly older and a greater proportion were male. There was a greater proportion of ankle fractures, fewer ankle sprains, and more open fractures presenting during the pandemic. A greater proportion of patients presenting to the emergency department were admitted (18.2% vs 12.5%). The 30-day readmission (n=13 [5.8%] vs n=38 [9.3%]) and mortality (n=4 [1.8%] vs n=3 [0.7%]) rates for admitted patients were similar ( P =.114 and P =.232, respectively). The authors found that 9.6% of patients who presented had a positive COVID-19 polymerase chain reaction test result and that these patients had 20% mortality and readmission rates.

Introduction: Musculoskeletal foot and ankle injuries are commonly experienced by soldiers during military training. We performed a systematic review to assess epidemiological patterns of foot and ankle injuries occurring during military training., Methods: A review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search, done on 14 February 2019, resulted in 1603 reports on PubMed, 565 on Embase and 3 on the Cochrane Library. After reading the remaining full-text articles, we included 91 studies., Results: Among a population of 8 092 281 soldiers from 15 countries, 788 469 (9.74%) foot and ankle injuries were recorded. Among the 49 studies that reported on length of training, there were 36 770/295 040 (18.17%) injuries recorded among women and 248 660/1 501 672 (16.56%) injuries recorded among men over a pooled mean (±SD) training period of 4.51±2.34 months. Ankle injuries were roughly 7 times more common than foot injuries, and acute injuries were roughly 24 times more common than non-acute injuries. Our findings indicated that, during a 3-month training period, soldiers have a 3.14% chance of sustaining a foot and ankle injury. The incidence of foot or ankle injury during military parachutist training was 3.1 injuries per thousand jumps., Conclusions: Our findings provide an overview of epidemiological patterns of foot and ankle injuries during military training. These data can be used to compare incidence rates of foot and ankle injuries due to acute or non-acute mechanisms during training. Cost-effective methods of preventing acute ankle injuries and non-acute foot injuries are needed to address this problem., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Turf toe injuries have been increasing in numbers in recent years. Injury to the plantar restraints of the first metatarsophalangeal joint can lead to significant disability in athletes, affecting their push-off and ability to perform on the athletic field. Most turf toe injuries can be treated conservatively with rest, ice, compression, immobilization if needed, and a dedicated rehabilitation program; however, in some injuries, the plantar restraints are torn and the joint becomes unstable. If necessary, turf toe injury and its many variants can be surgically repaired with the expectation that the athlete will be able to return to play., Competing Interests: Disclosure The author has nothing to disclose in relation to the content to this article., (Copyright © 2020 Elsevier Inc.

In athletes, foot injuries present with a variety of mechanisms, severity, and implications for return to play. Although potentially given less attention than knee and shoulder injuries by the team physician, foot injuries are common and thus require knowledgeable consideration. In this article, we review the anatomy, presentation, workup, and management of several of the most common athletic foot injuries, including turf toe, Lisfranc injuries, Jones fractures, and navicular stress fractures. The goal is to provide the team physician with the information necessary to evaluate and manage these injuries on the sideline and in the training room., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2020 Elsevier Inc.

Background: Lisfranc injuries encompass large spectrum of injuries varying from low energy to high energy complex fracture dislocations. Whilst multiple complex classification systems exist; these do little to aid and direct the clinical management of patients. Therefore, this study aims to provide a simplified treatment algorithm allowing clinicians to standardise care of Lisfranc injuries., Methods: A comprehensive literature search was performed, and abstracts were reviewed to identify relevant literature., Results: Delay in diagnosis has a negative impact on outcome. If a Lisfranc injury is suspected and plain radiographs are inconclusive; computed tomography and if necessary magnetic resonance imaging are indicated if there is still an index of suspicion. In the absence of joint dislocation/subluxation management will be determined by stability which can be best assessed by weightbearing radiographs. If stable, injuries can be treated conservatively in a non-weight bearing cast for 6 weeks followed by a period of graduated weight bearing. Evidence is mounting that with regard to unstable purely ligamentous Lisfranc injuries primary arthrodesis (PA) has: better functional outcomes, increased cost effectiveness and reduced rates of return to theatre. With regard to bony unstable Lisfranc injuries more research is required before a single treatment modality - PA or open reduction internal fixation can be advocated, due to the lack of randomized control trials and limited patient follow-up periods in existing studies., Conclusion: A simplified treatment algorithm excluding the requirement for complex classifications is suggested. This may help with the diagnosis and management of these injuries. It is our believe that this algorithm will aid health professionals to standardize care for these injuries. Further prospective research trials are required to assess outcomes of different modalities of operative management, particularly with regards to open reduction and internal fixation versus primary arthrodesis for bony Lisfranc injuries., Level of Evidence: Level 5., (Copyright © 2020 The Authors.

Surgical management of osteochondral lesions of the talus without an osteotomy depends on the size, location, and chronicity of the lesion. Bone marrow stimulation techniques, such as microfracture, can be performed arthroscopically and have consistently good outcomes in lesions less than 1 cm in diameter. For lesions not amenable to bone marrow stimulation, one-stage techniques, such as allograft cartilage extracellular matrix and allograft juvenile hyaline cartilage, may be used. Arthroscopy may be used in many cases to address these lesions; however, an arthrotomy may be required to use osteochondral autograft and allograft transplantation techniques., Competing Interests: Disclosure M.

Lisfranc injuries can be devastating to the athlete and nonathlete. In the athletic population, minor loss of midfoot stability compromises the high level of function demanded of the lower extremity. The most critical aspect of treatment is identifying the injury and severity of the ligamentous/articular damage. Not all athletes are able to return to their previous level of function. With appropriate treatment, a Lisfranc injury does not mandate the cessation of an athletic career. We focus on the diagnosis and an algorithmic approach to treatment in the athlete discussion the controversy of open reduction and internal fixation versus arthrodesis., Competing Interests: Disclosure Arthrex – Consultant, Speaker’s Bureau., (Copyright © 2020 Elsevier Inc.

Painful accessory navicular and spring ligament injuries in athletes are different entities from more common posterior tibialis tendon problems seen in older individuals. These injuries typically affect running and jumping athletes, causing medial arch pain and in severe cases a pes planus deformity. Diagnosis requires a detailed physical examination, standing radiographs, and MRI. Initial treatment focuses on rest, immobilization, and restriction from sports. Orthotic insoles may alleviate minor pain, but many patients need surgery to expedite recovery and return to sports. The authors review their approach to these injuries and provide surgical tips along with expected rehabilitation to provide optimal outcomes., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2020 Elsevier Inc.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly identified strain of coronavirus in the human body and was reported in Wuhan at the end of 2019. So far, the epidemic is continuing and very serious, with the number of infections and deaths increasing. Despite active investigations around the world to better understand the dynamics of transmission and the scope of clinical disease, COVID-19 continues to spread rapidly from person to person. The common signs and symptoms of SARS-CoV-2 infection include fever, fatigue, dry cough, and dyspnea; in severe cases, patients may have acute respiratory distress syndrome, septic shock, metabolic acidosis difficult to treat and coagulation disorder. However, some patients who test positive for SARS-CoV-2 in their respiratory tract may not have such clinical signs and symptoms. This report presents a case study analysis of a patient admitted in the Fourth Taiyuan People's Hospital, who had suffered traumatic injuries from a car accident and survived COVID-19, with pleural effusion as the initial symptom. We report a case of 2019-NCOV with pleural effusion as the first symptom. Describe in detail the differential diagnosis, diagnosis, clinical management, and cure of this case. In order to combat the novel CoronaviruscoVID-19 in the process to provide lessons and help.

Purpose: Foot problems can adversely impact foot function and quality of life. Foot problems are often overlooked, particularly in populations with limited health care access. Little is known about the foot health of Haitian immigrants who live and work in the bateyes (rural sugarcane villages) of the Dominican Republic. These immigrant workers may experience foot problems that could affect foot function and the ability to work and provide for their families., Design: Cross-sectional, exploratory, descriptive study design., Subjects and Setting: A convenience sample of adults was recruited from an ongoing community-based participatory research project evaluating a mobile hypertension screening and treatment clinic program in 11 Dominican batey communities., Methods: Foot health was assessed using the Foot Problems Checklist, a 24-item survey instrument developed for this study based on a review of the literature and foot clinician expertise. A certified foot care nurse recorded foot health data on the Foot Problems Checklist via visual and physical inspection., Results: Study participants were 25 females and 16 males, aged 18 to 90 years, and all had at least one foot health problem. The most common foot problems were calluses (78%), dry skin (76%), thick nails (59%), jagged nails (29%), long/overgrown nails (17%), and skin fissures (12%)., Conclusions: While the foot problems we observed were not considered serious, they could become progressively debilitating and be prevented with proper self-management guided by appropriate knowledge and skills and available supplies. We recommend the development and testing of foot care self-management interventions deliverable via mobile clinics to increase access and improve foot health outcomes.

A missed diagnosis of one of these conditions risks delay in referral for orthopedic evaluation and surgical management-possibly leading to complications.

Foot and ankle injuries account for a significant volume of primary care office visits each year. Given the incidence of injury and concern for long-term sequelae, it is imperative that primary care physicians familiarize themselves with commonly encountered foot and ankle injuries. Coupling a sound understanding of key anatomic structures with an appropriately gathered history can help to quickly narrow the differential diagnosis in this clinical presentation. This article focuses on key elements from the history and physical examination as well as provides a concise review of imaging modalities and recommended treatment strategies., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2019 Elsevier Inc.

Objective : To describe the evaluation, management and recovery time of hallux sesamoid fractures in young athletes. Methods : A retrospective chart review was performed in a large academic teaching institution over a 5-year period (1/1/2010-12/31/2014). All patients with a sesamoid injury were initially included. Excluded were those patients who: 1) did not receive the diagnosis of hallux sesamoid fracture, had a history of prior foot surgery, or had medical records inadequate for analysis, 2) had missing or unclear diagnostic imaging, 3) were age >21 years, or 4) did not report sports participation. Descriptive statistics were employed to analyze the data. Results : Fifty-eight patients (51 females and 7 males) with a mean age of 15.4 years (range: 9-21) were identified with a total of 59 sesamoid fractures. Dancing (37.9%), running (13.8%), and gymnastics (13.8%) were the most common sports reported among these patients. A greater number of fractures were classified as repetitive stress injuries (83.1%), rather than acute traumatic injuries (16.9%). Fractures were treated conservatively in the majority of cases (89.8%), and only six fractures (10.2%) were treated surgically. Most patients (84.7%) were able to return to sports and activities. The average time from diagnosis/start of treatment to pain-free state/cleared to return to sport was 161.4 days. Conclusion : Diagnosis of sesamoid fractures can be challenging, but overall most patients do well with conservative treatment and are able to return to sports and activities. Providers should keep sesamoid fracture in the differential when evaluating patients with pain in the area around the base of the first toe, especially in dancers, gymnasts, and runners. Understanding that the recovery from a sesamoid fracture can be a prolonged process may help patients develop realistic expectations.

Managing acute wounds with soft tissue loss can be very challenging for both patients and physicians. Successful wound healing depends on several factors including exudate control, prevention of infection, and moisture balance. In this case series, we describe a novel combination treatment method utilising small intestinal submucosa wound matrix (SISWM) with the bolster technique as a way of assisting the integration of collagen-based wound treatment products into the base of complex wounds with the intent of restoring a dysfunctional extracellular matrix. In case 1, a 44-year-old female presented with an acute wound resulting from a spider bite to the posterior aspect of the right knee. In case 2, a 12-year-old male sustained multiple injuries to his right foot from an all-terrain vehicle accident. In case 3, an 80-year-old female on anticoagulants sustained an avulsion injury to her left lower leg. In case 4, a 41-year-old female sustained a severe complex avulsion injury to the dorsal left forearm sustained from a dog bite. All patients were successfully treated with SISWM and the bolster technique, and their wounds healed completely within 6 weeks. The bolster technique, when combined with an SISWM, is a novel method designed to enable the SISWM to impart its wound healing properties to these complex traumatic wounds. This case series presents treating clinicians with a different treatment methodology to assist the patient in achieving a successful outcome., (© 2019 The Authors.

Objective: The goal of the present study was to compare the diagnostic yield of weight-bearing radiographs with non-weight-bearing computed tomography (CT) scan for subtle Lisfranc (LF) injuries in the ED., Methods: Retrospective analysis of patients presenting with a suspected LF injury over a 2 year period from 2016 to 2017 who had both weight-bearing bilateral foot radiographs and CT scan. Information extracted included patient demographics, radiographic findings of metatarsal fractures, fleck sign and measurements of diastasis between the medial cuneiform and second metatarsal expressed as a ratio of the uninjured side, clinical findings and treatment modality. Radiologist reports were recorded as either positive, negative or equivocal for a LF injury., Results: A total of 117 patients were included with a mean age of 38 years and 54% (n = 63) women. When initial weight-bearing radiographs were positive, 54% of subsequent CT scans were reported as either equivocal or negative. Of the patients who had a negative or equivocal weight-bearing radiograph, only 12% had a positive CT scan. The mean diastasis ratio in patients undergoing surgery was 1.53 (95% confidence interval 1.41-1.65) compared to 1.11 (95% confidence interval 1.07-1.16) for patients with injuries not requiring operative intervention (P < 0.001). There was a statistically significant correlation between a positive weight-bearing radiograph and surgical treatment (R = 0.339, P < 0.001), and between diastasis measurements and surgical treatment (R = 0.576, P < 0.001)., Conclusions: CT provides limited benefit in the diagnosis and initial management of suspected subtle LF injuries in the ED. We advocate for the use of bilateral weight-bearing radiographs as a first-line investigation., (© 2019 Australasian College for Emergency Medicine.)

Purpose: The purpose of this study was to define the fracture type and investigate the injuries related to single medial, intermediate, or lateral cuneiform fracture., Methods: From January 2008 to December 2018, 30 consecutive patients (30 cases) who were treated in the single institution for the single cuneiform fractures were reviewed retrospectively. Each fracture was categorized by location and type (intra- or extra-articular avulsion, axial compression, and direct blow). We also investigated the related foot bone fractures or dislocations on the affected side., Results: Twenty-one, one, and eight cases with single medial, intermediate, and lateral cuneiform bone fractures, respectively, were identified. More than two-thirds of the single cuneiform fractures were observed in the medial cuneiform bone. The single medial cuneiform fracture was associated with various types of foot injuries including Lisfranc injury, naviculo-cuneiform joint dislocation, or calcaneo-cuboidal dislocation. Single lateral cuneiform fractures were more frequently observed than single intermediate cuneiform fractures., Conclusion: More than two-thirds of the single cuneiform fractures were observed in the medial cuneiform bone. Most intra-articular avulsion fractures were associated with high-energy trauma., Level of Evidence: 4.

Background: This retrospective study was conducted to compare the outcomes between the free deep inferior epigastric artery perforator (DIEP) flap and the circumflex scapular artery perforator (CSAP) flap in reconstruction of moderate-sized soft tissue defects in the foot and ankle of pediatric patients., Patients and Methods: From January 2004 to December 2016, 42 patients, ranging from 2 to 13 years old, underwent foot and ankle reconstruction, with a free DIEP flap in 21 cases and a free CSAP flap in the other 21cases., Results: All the flaps survived. No marked differences were observed in the demographics, flap size, recipient vessels, and overall early or late complication rate (p > 0.05). The CSAP group had a shorter operation time (134.3 ± 25 min vs. 202.4 ± 24.3 min, p < 0.05) and flap harvest time (29.7 ± 8.1 min vs. 52.2 ± 9.8 min, p < 0.05) than the DIEP group had. In long-term follow-up, the CSAP group showed a lower fat hyperplasia rate (14% vs. 52%, p < 0.05) and better cosmetic outcomes than the DIEP group did (p < 0.05). The functional outcomes had no marked differences (p > 0.05)., Conclusions: The DIEP flap and the CSAP flap are both good options for foot and ankle reconstruction of moderate-sized defects in pediatric patients. The CSAP flap has a shorter operation time and flap harvest time, a lower fat hyperplasia rate, and better long-term cosmetic outcomes than the DIEP flap does., (Copyright © 2019 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Medial collateral ligament injury of the first metatarsophalangeal (MTP) joint is rare. If it is missed, chronic instability and traumatic hallux valgus develop, requiring surgical treatment. Different methods have been reported in the limited available literature aiming to restore the balance between the lateral and medial stabilizers by tightening the medial joint capsule with or without additional tendon graft. Our described method utilizes a suture button device (Mini TightRope, Arthrex, Naples, Florida) for reconstruction. This device applies tension to hold the hallux in the correct position, providing stability. Relevant diagnostic regimen, surgical technique, and postoperative care are described, along with a case of a handball player who underwent this procedure. He continues to perform at the same level 38 months postoperatively. Mini TightRope fixation for chronic medial first MTP instability has not been reported. It does not require postoperative immobilization and allows faster return to sport, so it seems superior to other methods when treating athletes.

Lisfranc injuries remain a frequently missed pathology and may present as an isolated injury or as a component of a polytrauma case. Weight-bearing films or advanced imaging such as CT may be imperative in identifying or further classifying the injury. Common indications for fusion after lisfranc injury include primarily ligamentous injuries, delayed/chronic presentations, or post-traumatic arthritis, although primary fusion in the setting of acute fracture may be considered as an alternative to open reduction internal fixation techniques. The primary goals of surgery are to provide stability to the midfoot and restoration of the anatomical arch/cascade. The purpose of this video is to demonstrate a technique for tarsometatarsal joint fusion in the setting of acute lisfranc injury. This technique may be used for both ligamentous as well as bony varieties.

To report the simultaneous occurrence of psoriatic arthritis (PsA) and chronic regional pain syndrome type I (CRPS I) both triggered by intense walking in a male golfer with a history of scalp psoriasis. Sequential existence of these two conditions have been reported in the literature; however, to our knowledge, this is the first report of a simultaneous occurrence of PsA and CRPS I. This case illustrates the complex interplay between genetic predisposition and environmental risk factors with the central nervous and immune systems. As the pathogenesis of PsA has been better understood in recent years, we propose a mechanism that explains how the release of pro-inflammatory cytokines and neuropeptides following a traumatic event elicits a vicious cycle that is a common ground for the development of both PsA and CRPS I. Even unperceived trauma, such as intense walking, when directed to the synovio-entheseal complex, can precipitate the development of PsA and CRPS I in predisposed individuals.

Introduction: Many studies focusing on musculoskeletal disorders or injuries have been performed in countries where the army is recruited as volunteers. Little is known about foot and ankle disorders among young men in conscript armies., Materials and Methods: We studied the incidence and risk factors of foot and ankle disorders in 4,029 Finnish army male conscripts of the same age among five different cohorts born in 1969, 1974, 1979, 1984, or 1989. Data were collected from the medical reports of the Finnish Defence Forces. Self-reported symptoms and diseases detected in the health examination prior to military service, and information obtained from visits to garrison health care centers were analyzed., Results: A total of 1,623 conscripts visited health care professionals due to foot or ankle disorders during their military service. About 511 (31.5%) of those had suffered an injury. The majority of the visits to garrison health care centers due to foot or ankle disorders occurred during the first few months of military service. Smoking, flatfoot deformity, previous injuries, and Class A military service were statistically significantly related with the incidence of foot or ankle disorders. There were statistically significantly less foot and ankle disorders if previous mental symptoms were reported. The data suggest that poor adaptation to physically demanding military training may cause foot and ankle disorders among many conscripts., Conclusions: The study shows that foot and ankle disorders are common in this population. Most of them occur in the first 2 months of the military service. Further analysis of different conditions was not possible, as many of the diagnostic codes were missing., (© Association of Military Surgeons of the United States 2018. All rights reserved.

Background: Missed or underestimated injuries are one of the central problems in trauma care. Foot injuries can easily be missed because they lay beyond the regularly screened field of a trauma computer tomography scan (CT scan). During primary and secondary survey a careful examination of the extremities often becomes of secondary interest in the severely injured patient., Methods: Thirty-four thousand ninety-one multiple trauma patients of the TraumaRegister DGU® were evaluated from 2002 to 2014. We differentiated between patients with foot injuries, patients with missed foot injuries and patients without foot injuries. Included were ankle fractures, calcaneus fractures, talus fractures, metatarsal fractures, toe fractures, amputation, soft tissue injuries and/or ligamentous injuries., Results: Summarized evaluation of 34,091 trauma patients showed a share of 2532 patients with foot injuries. Time of diagnosis was documented in 2199 cases. 2055 patients had early diagnosed foot injuries and 144 patients had initially missed foot injuries. Missed foot injuries were especially found in patients with car accidents or fall from ≥3 m. Patients with higher Abbreviated Injury Scale (AIS) or lower Glasgow Coma Scale (GCS) were not significantly more affected by missed foot injuries. Missing foot injuries was also not caused by injury severity or higher age., Conclusions: Our data highlights the need of careful evaluation of the feet during primary and secondary survey particularly when a tibia or femur fracture is diagnosed. Special attention should be turned to patients after car accidents or fall from great height. Suicide victims also need major attention. Patients with early operations also need careful examination and tertiary survey is highly recommended.

The reverse sural artery (RSA) flap is popular among trauma surgeons to cover the distal third of the leg to the foot. However, flaps that inset in the foot seem to have a high necrosis rate. This study compared the healing of RSA flaps performed for defects proximal to the ankle versus defects distal to the ankle. Patient data were collected retrospectively between January 2005 and December 2009. Eighty-five patients with the lower leg, ankle, and traumatic foot injuries were divided into 2 groups. Group 1 (49 patients) had RSA flap cover for soft tissue and bony defect proximal and up to the ankle joint line, and group 2 (36 patients) had RSA flap cover distal to the ankle joint line. The time to healing and type of healing were compared between the groups. The demographics between the 2 groups were similar. The successful RSA flap healing rate was 65% in group 1 (32 of 49) and 42% in group 2 (15 of 36). The average time to flap healing between the groups was similar (p = .16). Group 1 had predominantly primary healing compared with group 2 (p = .03). Group 2 had a higher reoperation rate for wound necrosis, which was significant (p = .001). The success of the RSA flap is higher when used for proximal to ankle joint line defects. Surgeons should be aware of the chances of flap necrosis when undertaking RSA flap cover distal to the ankle joint line., (Copyright © 2018 the American College of Foot and Ankle Surgeons.

Injuries to the tarsometatarsal joint complex, also referred to as a Lisfranc injury, are relatively uncommon presentations to emergency departments (EDs), however accurate diagnosis is vital to prevent the risk of long-term disability. Advanced nurse practitioners (ANPs) must use a broad range of clinical skills to manage patients' injuries effectively. A high level of suspicion, recognition of the clinical manifestations of Lisfranc injury and appropriate radiographic images are required to formulate a correct diagnosis. This article describes Lisfranc injuries, revises the anatomy of the midfoot, and discusses diagnosis and management. It includes a case study to illustrate assessment and management of a patient who presented to an ED with a Lisfranc injury following a fall from a height and considers the diagnostic decisions and management options available to ANPs., Competing Interests: None declared, (©2019 RCN Publishing Company Ltd.

Turf toe injuries can be a disabling if not recognized and treated early. A high index of suspicion, based on the mechanism of injury and appropriate imaging, helps in the timely diagnosis. These injuries are frequently known to occur on artificial playing surfaces, because of the increased traction at the shoe-surface interface. Stress and instability testing are key components to assess the need for surgical intervention. Accurate timely diagnosis and treatment can allow full return to physical activities for most athletes, back to their pre-injury level., (Crown Copyright © 2018. Published by Elsevier Inc.

The ankle is one of the most commonly injured joints in soccer and represents a significant cost to the healthcare system. The ligaments that stabilize the ankle joint determine its biomechanics-alterations of which result from various soccer-related injuries. Acute sprains are among the most common injury in soccer players and are generally treated conservatively, with emphasis placed on secondary prevention to reduce the risk for future sprains and progression to chronic ankle instability. Repetitive ankle injuries in soccer players may cause chronic ankle instability, which includes both mechanical ligamentous laxity and functional changes. Chronic ankle pathology often requires surgery to repair ligamentous damage and remove soft-tissue or osseous impingement. Proper initial treatment, rehabilitation, and secondary prevention of ankle injuries can limit the amount of time lost from play and avoid negative long-term sequelae (eg, osteochondral lesions, arthritis). On the other hand, high ankle sprains portend a poorer prognosis and a longer recovery. These injuries will typically require surgical stabilization. Impingement-like syndromes of the ankle can undergo an initial trial of conservative treatment; when this fails, however, soccer players respond favorably to arthroscopic debridement of the lesions causing impingement. Finally, other pathologies (eg, stress fractures) are highly encouraged to be treated with surgical stabilization in elite soccer players., Competing Interests: Authors' Disclosure Statement: The authors report no actual or potential conflict of interest in relation to this article.

Near infrared spectroscopy (NIRS) is a technique whereby light is transmitted to the skin or the surface of a wound. Light is selectively absorbed or reflected in order to calculate the percentage of oxygenated and deoxygenated hemoglobin. By calculating this ratio, the level of tissue oxygen perfusion can be assessed. This article describes an NIRS imaging device and demonstrates its use as a clinical tool to predict future viability of skin flaps, potential for wound healing, and progress of closure following application of a biologic wound product. Several cases are examined., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: Due to prioritizing care and concomitant injuries, foot fractures in polytrauma patients often receive limited attention initially. However, as foot function is important, treatment and diagnosis of these fractures should be accurate. The aims of this study were to assess the incidence and distribution of foot fractures in polytrauma patients and to examine possible risk factors for delayed diagnosis of foot fractures., Methods: This was a retrospective study on all adult (≥18 years) polytrauma (ISS ≥16) patients admitted to a single level 1 trauma center between 2006 and 2016. Patients with foot fractures were identified by diagnosis codes. Data on demographics and trauma characteristics were collected from the Trauma Quality Improvement Program (TQIP ® ) database. Data on foot fractures were gathered from electronic patient documentation., Results: Out of 4409 polytrauma patients, 221 (5.0%) sustained a total of 511 foot fractures. Metatarsal fractures were most common (41%), followed by calcaneal (17%), and talar (16%) fractures. Thirty percent of the fractures in 33% of all patients were diagnosed in a delayed fashion. This had treatment consequences in 8%. Delayed diagnosed fractures were more common in older patients (p 0.025), patients with a higher ISS (p 0.012), ICU admission (p 0.015), and concomitant head injury (p 0.020)., Conclusions: As one in twenty polytrauma patients sustains at least one foot fracture and a substantial amount of these fractures are diagnosed in a delayed fashion, physicians, regardless of their specialty, should have a high index of suspicion for injuries of the feet in polytrauma patients., (Copyright © 2018 Elsevier Ltd.

The heel comprises the epidermis, minimal subcutaneous tissue, a dense septum, and the calcaneus. Injury to any of these structures can impair the ability to walk. The soft tissue or calcaneal bone can be injured by trauma. Injuries incurred in war are usually high-energy traumas caused by weapons such as rifles, rockets, and land mines. Such injuries can be life threatening and involve the loss of tissue, including skin, soft tissue, bone, and neurovascular tissue. Two main treatment protocols are used for such injuries with large tissue defects: amputation and reconstruction. We describe a reconstruction with an osteomyocutaneous fibular flap for a heel injury. At the 2-year follow-up point, the patient had 30% loss of ankle range of motion. The visual analog scale score had dramatically decreased from 8 to 1, and the patient was satisfied with the result. In conclusion, patients with significant problems such as infection, pain, and anatomic deterioration of the calcaneus can be successfully treated using an osteomyocutaneous fibular flap in a single surgery., (Copyright © 2017 The American College of Foot and Ankle Surgeons.

Management of complex foot injuries, which involve open fractures and severe trauma to soft tissues, represent a challenge to orthopedic clinicians. In the present case report, we treated a complex foot injury with a remodeled fibular osteocutaneous free flap to reconstruct the anterior and lateral areas of the foot. The flap survived completely. At the 9-month follow-up examination, bony union of the graft bone was identified by radiographic examination. The reconstructed foot could bear body weight, and the patient could maintain a bipedal gait without discomfort. The remodeled fibular osteocutaneous free flap provides an option for functional reconstruction of foot defects., (Copyright © 2017 The American College of Foot and Ankle Surgeons.

Patient-reported outcomes (PROs) are a measure of health care quality that empower patients to share their health care perceptions with their providers. In orthopedic foot and ankle surgery, these measures can range from global assessments of pain or satisfaction to complex questionnaires designed to assess the function of specific anatomic regions or the recovery from specific procedures. This article seeks to characterize the use of PROs in foot and ankle surgery, describe some of the most commonly used measures, discuss implementation in everyday clinical practice, and explore the future of PROs in foot and ankle orthopedics., (Copyright © 2017 Elsevier Inc.

The tarsal navicular is a critical component of the foot's medial longitudinal arch. Injuries to the navicular have significant long-term functional consequences. In addition to stress fractures, acute injuries to the navicular include acute avulsion, tuberosity, and body fractures. Nonoperative treatment is the mainstay for avulsion injuries and nondisplaced body fractures. Open reduction and internal fixation is performed to achieve anatomic reduction in the other situations. Common complications following operative intervention include pain, stiffness, post-traumatic arthritis, avascular necrosis, nonunion, and hindfoot deformity. This article provides an overview for recognition and treatment of common presentations of these injuries as described in the literature., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: Forefoot fractures account for 6% to 10% of fractures in children, and although the majority heals with supportive treatment, complications may lead to pain and disability. No previous study in children has evaluated complication risk in the emergency department based on initial assessment characteristics., Study Objectives: The study aim was to identify the radiological and clinical variables that increase the complication rate of pediatric forefoot fractures. This may help emergency physicians refer patients who require more thorough follow-up or surgical intervention., Methods: We evaluated 497 forefoot fractures on initial presentation to a pediatric emergency department at the Children's Hospital at London Health Science Centre over a 6-year period. We collected variables such as degree of angulation, displacement, number of concurrent fractures, and demographic data such as age and sex. We then determined the variables associated with complications by reviewing each patient's chart., Results: Overall, there was a 6.4% complication rate. Analysis identified sex as an important predictor of complications. Females, although representing approximately one third of the sample, represented nearly two thirds of the cases with complicated outcomes (P = 0.001; odds ratio [OR], 4.67). Increased number of fractures was also significant (P = 0.01; OR, 2.41) as was increasing age (P = 0.01; OR, 1.17) and patients who chose to return to the emergency department (P < 0.05; OR, 5.282). Lateral angulation/displacement and anteroposterior angulation/displacement were not associated with increased complications., Conclusion: Identifying features, such as female sex, increasing age, multiple fractures, and return to emergency departments for repeat visits, may help guide the emergency physician on whom to refer for specialized care.

Acute compartment syndrome of the foot and ankle is a relatively rare clinical finding. Lower extremity compartment syndrome is customarily due to vascular or orthopedic traumatic limb-threatening pathologic issues. Clinical correlation and measurement of intracompartmental pressure are paramount to efficient diagnosis and treatment. Delayed treatment can lead to local and systemically adverse consequences. Frostbite, a comparatively more common pathologic entity of the distal extremities, occurs when tissues are exposed to freezing temperatures. Previously found in military populations, frostbite has become increasingly prevalent in the general population, leading to more clinical presentations to foot and ankle specialists. We present a review of the published data of acute foot compartment syndrome and pedal frostbite, with pathogenesis, treatment, and subsequent sequelae. A case report illustrating 1 example of bilateral foot, atraumatic compartment syndrome, is highlighted in the present report. The patient presented with changes consistent with distal bilateral forefoot frostbite, along with gangrenous changes to the distal tuft of each hallux. At admission and evaluation, the patient had increasing rhabdomyolysis with no other clear etiology. Compartment pressures were measured in the emergency room and were >100 mm Hg in the medial compartment and 50 mm Hg dorsally. The patient was taken to the operating room urgently for bilateral pedal compartment release. Both pathologic entities have detrimental outcomes if not treated in a timely and appropriate manner, with amputation rates increasing with increasing delay., (Copyright © 2018 American College of Foot and Ankle Surgeons.

The foot is considered the second most common location for foreign bodies. The most common foreign bodies include needles, metal, glass, wood, and plastic. Although metallic foreign bodies are readily seen on plain film radiographs, radiolucent bodies such as wood are visualized poorly, if at all. Although plain radiography is known to be ineffective for demonstrating radiolucent foreign bodies, it is often the first imaging modality used. In such cases, complete surgical extraction cannot be guaranteed, and other imaging modalities should be considered. We present a case of a retained toothpick of the second metatarsal in a young male patient who presented with pain in the right foot of a few weeks' duration. Plain radiography showed an oval cyst at the base of the second metatarsal of the right foot. Magnetic resonance imaging revealed a toothpick penetrating the second metatarsal. The patient recalled stepping on a toothpick 8 years previously. Surgical exploration revealed a 2-cm toothpick embedded inside the second metatarsal.

The plantar plate and associated collateral ligaments are the main stabilizers of each of the lesser metatarsophalangeal joints. Although clinical examination and plain radiographs are usually sufficient to establish the diagnosis of a plantar plate tear, MRI or fluoroscopic arthrograms may help in specific cases. Recent results with a dorsal approach to plantar plate repair are promising with respect to pain relief and patient satisfaction., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Lisfranc injuries are relatively uncommon. No specific incidence of subtle injuries has been reported; however, almost one-third are missed on initial review. These missed injuries are a common cause of litigation. Although seen in high-energy injuries with direct application of forces, they are also associated with lower-energy indirect mechanisms, often on the athletic field. This article provides a topical review of subtle Lisfranc disruptions, focusing on contemporary perspectives, and describes a modification to the most prevalent classification system.

The midfoot and forefoot are the regions of the foot distal to the talus and calcaneus and are critical to weight bearing and movement. They help support the arch of the foot, provide shock absorption, and convert vertically oriented forces into horizontal forward and propulsive movement. A spectrum of acute, subacute, and chronic conditions in these regions can cause pain and decreased function. A thorough history and physical examination should include foot and leg biomechanics, alignment, and posture in addition to palpation of painful areas. All patients with traumatic or overuse midfoot and forefoot injuries should be evaluated with x-rays, with the need for advanced imaging determined based on initial findings. Appropriate diagnosis and management of Lisfranc joint injuries and navicular and base of the fifth metatarsal stress fractures can prevent adverse outcomes. Management of these injuries commonly includes a period of non-weight-bearing immobilization and referral to an orthopedic surgeon. Turf toe, hallux rigidus, metatarsalgia, and Morton neuroma are common causes of forefoot pain. Treatment should be individualized and may include shoe and orthotic adjustments, injections, and, occasionally, surgical intervention., (Written permission from the American Academy of Family Physicians is required for reproduction of this material in whole or in part in any form or medium.)

Objective: This case series describes four cases with a similar mechanism of injury: crush injuries to the foot from hydraulic presses/trailers. The aim of the study was to review a specific cohort of pneumatic compression injuries of the foot in terms of their soft-tissue component, and in particular relating to the burst lacerations., Method: The mechanism and patterns of injury were reviewed to identify common features in a case series of four crush injuries to the foot which presented to the Emergency Department of University Hospital Galway over a period of 6 months between January and July 2017., Results: There were four cases of high-energy crush injuries to the feet seen in involved farmers (mean age 55). The cases presented with similar soft-tissue injuries, despite having quite varied bony injuries. All patients had lacerations of the webbed spaces, which is likely due to extrusion of the interosseous muscles as they are flattened. Three patients had lacerations along the medial side of their foot extending transversely across the plantar surface., Conclusion: A common pattern of soft-tissue injury was present in these cases. We feel the term "burst laceration" is an appropriate term for describing this pattern. Burst lacerations are a marker of high-energy crush injuries and should alert surgeons to the severe soft-tissue injury that likely overlies the more obvious fracture. The importance of soft-tissue management in high-energy lower limb injury cannot be overstated. We feel the presence of burst lacerations to the foot should alert the surgeon to a high-energy crush-injury type mechanism of injury, and guide both soft-issue and bony management to optimize patient outcomes.

Fractures of the fifth metatarsal base are among the most common fractures of the foot. They are typically caused by indirect violence during sports activities. This region is also a site where stress fractures occur frequently. Diagnosis is based on the patients medical history, clinical examination and imaging methods. The fundamental imaging method is radiography of the foot in three views. MRI is used primarily for early diagnosis of stress fractures. CT examination is beneficial mainly in complex foot injuries, in order to rule out associated fractures. Several classifications of fractures of the fifth metatarsal base have been published in the last 50 years, categorizing these fractures in terms of their location, appearance of the fracture line, type of treatment, healing and complications. Currently, the most frequently used one is the classification developed by Lawrence and Botte. Non-operative treatment is indicated in undisplaced or minimally displaced fractures, fractures in elderly patients and in patients contraindicated for surgery. The method of choice in undisplaced fractures is the Barouk boot with partial weight-bearing as tolerated by the patient, while displaced fractures up to 2 mm are fixed in a low plaster cast (Essex-Lopresti shoe). Operative treatment is indicated in fractures displaced by more than 2 mm or involving more than 30% of the articular surface of the cuboid-metatarsal joint. Internal fixation is most commonly performed with the use of intramedullary screw, tension wire band, K-wires or plates. Stress fractures are preferably treated by surgery to reduce the risk of non-union, delayed healing and the risk of refractures. The most common complications associated with treatment of fractures of the fifth metatarsal base include delayed healing, non-union development, refractures and patient discomfort.Key words: fractures of the fifth metatarsal base - diagnosis - treatment - complications.
