Surgical intervention, such as the Broström-Gould procedure, is typically indicated for patients with chronic lateral ankle instability. In this study, we are comparing the safety and efficacy of the Broström-Gould procedure with peroneal tendon debridement, a sliding lateralizing calcaneal osteotomy, and adjuvant procedures performed with a single- versus double-incision approach. Our retrospective analysis included patients who underwent the procedure of interest between 2011 and 2020. Patients were divided into 2 groups: undergoing either a 1-incision (n = 53) or a 2-incision approach (n = 47), both with a lateralizing calcaneal osteotomy. A significant difference in skin bridge breakdown was observed between the 2-incision (n = 6 [13%]) and 1-incision groups (n = 0 [0%]). There were no significant differences in infection, deep wound dehiscence, nerve palsy, or neuroma between patients in the 2 groups. Furthermore, no statistically significant differences in mean PROMIS scores existed between the cohorts. The described Broström-Gould procedure shows promise for treating chronic ankle instability. While patients in both single- and double-incision groups had similar rates of postoperative complications, the decreased incidence of skin bridge breakdown in the 1incision group highlights the approach's safety and potential benefits in reducing wound-related complications., (Copyright © 2024.

While the Lapidus bunionectomy is a common procedure utilized to address hallux valgus, the incidence of secondary surgery is not well established. Our primary goal was to determine the incidence of revision surgery and hardware removal following the Lapidus bunionectomy in addition to the risk factors associated with each. A retrospective nested case-control study of adult patients who underwent a Lapidus bunionectomy for symptomatic hallux valgus over a 9-year period was performed. The incidence rates and 95% confidence intervals (CI) of secondary surgery in the 3 years following the procedure along with the estimated independent associations and odds ratios between baseline demographic, clinical, and radiographic characteristics were calculated. Of the original cohort of 2540 patients, 127 were identified (5.0%; CI: 4.1%, 5.8%) who underwent revision surgery and 165 (6.5%; CI: 5.5%, 7.5%) who underwent hardware removal following Lapidus bunionectomy. Initially, the hallux valgus angle, intermetatarsal angle, and tibial sesamoid position were risk factors for revision surgery. However, in adjusted analyses for revision surgery, using a screw for third point of fixation emerged as the only independent risk factor (odds ratio [OR] = 3.01; CI: 1.59, 5.69). In adjusted analyses for hardware removal, female sex (OR = 2.33; CI: 1.08, 5.00) and third point of fixation (OR = 2.92; CI: 1.82, 4.69) emerged as independent risk factors. While the overall risks associated with Lapidus bunionectomy are low and the need for revision surgery are low, this study helps to identify specific risk factors for secondary surgery and hardware removal to help in evaluation and discussion with patients., (Copyright © 2024 the American College of Foot and Ankle Surgeons.

Patients with threatened arteriovenous access are often found to have central venous stenoses at the ipsilateral costoclavicular junction, which may be resistant to endovascular intervention. Stenoses in this location may not resolve unless surgical decompression of thoracic outlet is performed to relieve the extrinsic compression on the subclavian vein. The authors reviewed the management of dialysis patients with central venous lesions at the thoracic outlet, as well as the role of surgical decompression with first-rib resection or claviculectomy for salvage of threatened, ipsilateral dialysis access., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this article., (Published by Elsevier Inc.)

The physical demands of sports can place patients at elevated risk of use-related pathologies, including thoracic outlet syndrome (TOS). Overhead athletes in particular (eg, baseball and football players, swimmers, divers, and weightlifters) often subject their subclavian vessels and brachial plexuses to repetitive trauma, resulting in venous effort thrombosis, arterial occlusions, brachial plexopathy, and more. This patient population is at higher risk for Paget-Schroetter syndrome, or effort thrombosis, although neurogenic TOS (nTOS) is still the predominant form of the disease among all groups. First-rib resection is almost always recommended for vascular TOS in a young, active population, although a surgical benefit for patients with nTOS is less clear. Practitioners specializing in upper extremity disorders should take care to differentiate TOS from other repetitive use-related disorders, including shoulder orthopedic injuries and nerve entrapments at other areas of the neck and arm, as TOS is usually a diagnosis of exclusion. For nTOS, physical therapy is a cornerstone of diagnosis, along with response to injections. Most patients first undergo some period of nonoperative management with intense physical therapy and training before proceeding with rib resection. It is particularly essential for ensuring that athletes can return to their baselines of flexibility, strength, and stamina in the upper extremity. Botulinum toxin and lidocaine injections in the anterior scalene muscle might predict which patients will likely benefit from first-rib resection. Athletes are usually satisfied with their decisions to undergo first-rib resection, although the risk of rare but potentially career- or life-threatening complications, such as brachial plexus injury or subclavian vessel injury, must be considered. Frequently, they are able to return to the same or a higher level of play after full recovery., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this article., (Copyright © 2024 Elsevier Inc.

Venous thoracic outlet syndrome (vTOS) is an esoteric condition that presents in young, healthy adults. Treatment includes catheter-directed thrombolysis, followed by first-rib resection for decompression of the thoracic outlet. Various techniques for first-rib resection have been described with successful outcomes. The infraclavicular approach is well-suited to treat the most medial structures that are anatomically relevant for vTOS. A narrative review was conducted to specifically examine the literature on infraclavicular exposure for vTOS. The technique for this operation is described, as well as the advantages and disadvantages of this approach. The infraclavicular approach is a reasonable choice for definitive treatment of uncomplicated vTOS., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

The Scarf osteotomy is a surgical procedure performed to correct a hallux valgus deformity. Multiple studies have supported use of the procedure with favorable outcomes. In contrast, there have been studies showing a significant complication rate with the procedure. Incidence of complications remains underreported in the literature. We performed a systemic review and meta-analysis examining a wide range of reported complications and associated clinical outcomes from the Scarf osteotomy. One hundred and sixteen publications were identified and 25 (21.6%) met our inclusion criteria. A total of 1583 Scarf procedures were included. Weighted mean follow-up was 26.4 months [range 12-168 months]. We found a 5.1% rate of recurrence, 3.5% rate of troughing, 1.0% rate of avascular necrosis, 1.8% rate of nonunion, 2.7% rate of malunion, 2.4% rate of infection, 5.3% rate of complex regional pain syndrome, and 3.4% rate of hallux varus. An average decrease in intermetatarsal angle of 6.3° was observed. No statistical difference was found in outcomes when comparing Scarf versus Scarf with additional procedure performed at time of surgery. To our knowledge, this systematic review and meta-analysis contains the highest number of Scarf procedures analyzed and presents complication rates on multiple adverse outcomes., (Copyright © 2022 the American College of Foot and Ankle Surgeons.

Metatarsalgia is a frequent foot disorder. The objective was to evaluate whether the length ratio between the second and the third metatarsals after Weil osteotomy influences clinical outcomes. This retrospective study included 37 patients (53 feet). Preoperative planning consisted of keeping the second metatarsal greater than or equal to the third metatarsal after Weil osteotomy of the second metatarsal or the second and third metatarsals. Based on postoperative weightbearing and digital AP radiographs after Weil osteotomy, we divided the patients into 2 groups: group 1, the second metatarsal was longer than or equal to the third metatarsal; and group 2, the second metatarsal was shorter than the third metatarsal. We investigated whether there were differences between the groups. In 35 (66%) feet, the second metatarsal was longer than or equal to the third metatarsal (group 1), and in 18 (34%) feet, the second metatarsal was shorter than the third metatarsal (group 2). Postoperative American Orthopaedic Foot and Ankle Society scores were 86.2 and 82.7, respectively (p = .32). Postoperative Visual Analog Scale scores were 1.26 and 1.67, respectively (p = .39). The sample showed 11.3% of transfer metatarsalgia to the third metatarsal. Group 1 had 9% of transfer metatarsalgia, whereas group 2 had 17% of transfer metatarsalgia (p = .40). The presence of a second metatarsal shorter than the third metatarsal, after Weil osteotomy of the second metatarsal or the second and third metatarsals, does not influence outcomes or incidence of transfer metatarsalgia to the third metatarsal., (Copyright © 2022 the American College of Foot and Ankle Surgeons.

Hallux valgus is associated with balance deficits, and has been implicated as an independent risk factor for falls in older adults. However, it is unknown what effect hallux valgus surgery has on static and dynamic (i.e., while walking) balance in older adults. We enrolled 13 middle-aged and older aged adults (mean age 54.3 ± 12.7 years, range 47 to 70) who underwent isolated hallux valgus surgery and followed them for 12 months. Preoperative and postoperative gait and balance performance was assessed using non-invasive body worn sensors with standardized and validated testing protocols. Visual analog scale (VAS) for pain and radiographic angles were also assessed. All subjects reported improvements in pain (VAS mean change -38.3 ± 10.3 mm), and all subjects demonstrated improvements in their hallux valgus angles and first/second intermetatarsal angles (mean change 16.3 ± 8.8°, and 5.5 ± 3.0°, respectively). While standing in full tandem, center of mass (COM) sway was improved upon by 59% at 1 year postoperative (p < .05, paired t-test). While most gait parameters demonstrated little change postoperatively, patients tended to spend less time in double support (p = .08, paired t-test), while gait variability increased by 55% (p = .03, paired t-test) and medial-lateral sway while walking increased by 43% (p = .08, paired t-test) 12 months postoperatively. Balance improved after hallux valgus surgery in our population, particularly when subjects were forced to rely on their operative foot for support (e.g., full tandem). Patients also seemed to walk with greater variability in stride velocity and with greater medial-lateral sway postoperatively, suggesting perhaps increased ambulatory confidence after successful hallux valgus surgery., (Copyright © 2021 the American College of Foot and Ankle Surgeons.

This article discusses the possible complications in minimally invasive surgery (MIS) for hallux valgus. The rate of complications and the outcomes are at least comparable with open techniques. A percutaneous technique provides the best conditions for undisturbed healing. Some possible complications exist in MIS that do not exist in open surgery, such as lesion of soft tissue structures that are not under direct visible control or skin burns. These complications usually result from technical mistakes in performing the operation. It is therefore crucial to get proper education from cadaver training and visiting experienced colleagues, as is done in open surgery., Competing Interests: Disclosure The author is a consultant for MAXXOS Medical GmbH., (Copyright © 2020 Elsevier Inc.

This article presents the indications, contraindications, preoperative surgical planning, surgical technique, and postoperative management of some of the most common percutaneous procedures in orthopedic foot and ankle surgery. The background of each procedure also is presented, supported by the latest in published literature to educate surgeons.

Minimally invasive (MIS) or percutaneous surgery has evolved rapidly through the development of novel techniques with precise description, correct indications, and the incorporation of modifications of safe and effective techniques described in open surgery. The correct term to describe these procedures should be percutaneous and MIS should be reserved for procedures between percutaneous and open surgery (eg, osteosynthesis). According to results, third-generation techniques are useful, effective, and easier than open procedures. It seems that MIS surgery has an extensive learning curve, and therefore it may be difficult to duplicate the results shown on already-published data., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2019 Elsevier Inc.

Complications following hallux valgus (HV) reconstruction will have an expected incidence of between 10% and 55% of cases. The more commonly reported complications include undercorrection/recurrence, overcorrection (hallux varus), transfer metatarsalgia, nonunion, malunion, avascular necrosis, arthritis, hardware removal, nerve injury, and ultimately patient dissatisfaction. The presence of arthritis will be an indication for fusion, whereas osteotomies will be the procedure of choice if the first metatarsophalangeal joint is healthy. Wide experience in primary HV surgery is advised before dealing with complex cases of failed HV surgery., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2019 Elsevier Inc.

Avascular necrosis (AVN), nonunion, malunion, and metatarsophalangeal (MTP) osteoarthritis following hallux valgus osteotomies, as well as pathophysiology, diagnosis, prevention strategies, and treatment are discussed in this article. AVN and nonunion are very infrequent, and they can be effectively prevented taking into consideration local anatomy preservation, biomechanics, and patient comorbidities. Shortening, elevation, plantarflexion, varus/valgus, and rotational of the first metatarsal are the most common types of malunion. They can lead to pain, stiffness, deformity recurrence, and transfer metatarsalgia. MTP osteoarthritis can develop after metatarsal malunion or AVN. Treatment options include cheilectomy, osteotomies to correct malunions, and MTP arthrodesis., Competing Interests: Disclosure The authors have nothing to disclose., (Copyright © 2019 Elsevier Inc.

Because of their inert character and desired biocompatibility, titanium implants have been universally accepted as safer alternatives to the conventional stainless steel orthopedic implants; however, recent emergence of type IV hypersensitivity reactions to titanium have included eczema, contact dermatitis, a prolonged febrile state, sterile osteonecrosis, and impaired fracture and wound healing. This report presents a patient with postoperative incision dehiscence and devascularization of surfaces in contact with titanium hardware after undergoing a double calcaneal osteotomy and a first metatarsal-cuneiform arthrodesis using titanium alloy implants. Titanium hypersensitivity was confirmed in this case through standard allergy patch testing by a board-certified immunologist. Complete healing occurred after diagnosis of the titanium allergy and hardware explant. To our knowledge, this is one of a few known allergies to titanium implants after foot and ankle surgery., (Copyright © 2018 the American College of Foot and Ankle Surgeons.

Recurrent deformity after surgical treatment of the cavus foot occurs because a procedure is not performed at the apex of the deformity. In many instances there are multiple apices and, in addition to hindfoot osteotomy or arthrodesis, the midfoot must be corrected. There is not much of a role for the Coleman block test to determine flexibility of the foot, and this has led to many failures where the foot was believed flexible and an osteotomy was insufficient treatment. Skeletal correction, even if perfect, does not last unless the foot is balanced with appropriate tendon transfers., (Copyright © 2019 Elsevier Inc. All rights reserved.)

The most common cause for end-stage ankle osteoarthritis is posttraumatic, sometimes resulting from concomitant supramalleolar deformity. Aims of the supramalleolar osteotomy include restoring the lower-leg axis to improve intraarticular load distribution and retarding degeneration of the tibiotalar joint. Preoperative planning is based on conventional weight-bearing radiographs. Often advanced imaging, including computed tomography and/or MRI, is needed for a better understanding of the underlying problem. Postoperative complications are not uncommon, including progression of tibiotalar osteoarthritis in up to 25% within 5 years of all patients who have supramalleolar osteotomies., (Copyright © 2019 Elsevier Inc.

Many different distal metatarsal osteotomies have been described in the surgical treatment of metatarsalgia. The surgeon should use such osteotomies judiciously, and indeed, in the author's experience, they are infrequently required and are certainly not a first port of call. In cases where nonoperative treatments have failed, a thorough understanding of the causes of metatarsalgia and a detailed clinical assessment of the patient are essential if good surgical outcomes are to be achieved. If using distal metatarsal osteotomies as part of the surgical plan, then the author favors extra-articular percutaneous osteotomies to minimize postoperative stiffness., (Copyright © 2017 Elsevier Inc.

Metatarsal osteotomies can be divided into proximal and distal. The proximal osteotomies, such as the oblique, segmental, set cut, and Barouk-Rippstein-Toullec (BRT) osteotomy, all provide the ability to significantly change the position of the metatarsal head without violating the joint. These osteotomies, however, have a high rate of nonunion when done without internal fixation and can lead to transfer metatarsalgia when done without regard to the parabola of metatarsal head position. Distal osteotomies such as the Weil and Helal offer superior healing but have an increased incidence of recurrent metatarsalgia, joint stiffness, and floating toe., (Copyright © 2017 Elsevier Inc.

Recurrence is common after hallux valgus corrective surgery. Although many investigators have studied the risk factors associated with a suboptimal hallux position at the end of long-term follow-up, few have evaluated the factors associated with actual early loss of correction. We conducted a retrospective cohort study to identify the predictors of lateral deviation of the hallux during the postoperative period. We evaluated the demographic data, preoperative severity of the hallux valgus, other angular measurements characterizing underlying deformities, amount of hallux valgus correction, and postoperative alignment of the corrected hallux valgus for associations with recurrence. After adjusting for the covariates, the only factor associated with recurrence was the postoperative tibial sesamoid position. The recurrence rate was ~50% and ~60% when the postoperative tibial sesamoid position was >4 and >5 on the 7-point scale, respectively., (Published by Elsevier Inc.)

Hallux abductovalgus is one of the most common deformities addressed by foot and ankle surgeons. Surgically, it can be approached using a wide variety of procedures. After performing the first metatarsal osteotomy, the final step is often to realign the great toe in a rectus position. This is performed with an osteotomy of the proximal phalanx. The Akin osteotomy is a medially based closing wedge osteotomy of the proximal phalanx. When executing the osteotomy, the goal is not only to correct abduction, but also to keep the lateral cortex intact, which allows it to act as an additional point of fixation. However, the lateral cortex can be iatrogenically compromised during surgery or in the postoperative period. We investigated the frequency of disruption of the lateral cortex, osteotomy displacement, healing time, and the need for surgical revision associated with the Akin procedure. A total of 132 patients who had undergone Akin osteotomy were included in the present retrospective study. Intraoperative fluoroscopy showed the lateral cortex was compromised in 47 (35.6%) patients and remained intact for 85 (64.4%) patients. Of the 47 (35.6%) patients with lateral cortex disruption intraoperatively, 9 (19.1%) experienced displacement during the postoperative period, of whom, 3 (6.38%) required surgical revision. Although intact during surgery, the other 6 (4.55%) patients sustained lateral cortex fractures postoperatively, 2 (33.3%) of whom required surgical revision. A statistically significant difference was found between the integrity of the lateral cortical hinge and the healing time of the osteotomy. All the osteotomies with displacement postoperatively were noted to have lateral cortex failure, either during surgery or during the follow-up period., (Copyright © 2017 American College of Foot and Ankle Surgeons.

Treatment of large osseous defects remains a difficult surgical challenge. Autografts and allografts have been known to undergo late collapse, because these options are not specifically designed to withstand the high loads of the foot and ankle. The inability to achieve the correct shape for reconstruction further limits their application. Large osseous defects will result during salvage after failed Lapidus bunionectomy, explantation of failed total ankle replacements, and nonunion of Evans calcaneal osteotomy. Each of 3 patients received a 4WEB custom 3-dimensional (3D) titanium truss implant (Patient Specific Custom Implant; 4WEB Medical, Inc., Frisco, TX) for reconstruction. The mean follow-up period was 17.33 ± 3.51 months. Significant improvement was seen in pain, with a successful return to activities of daily living. The 12-month postoperative computed tomography findings demonstrated incorporation of the implant to the surrounding cortical and cancellous bone. No signs of delayed complications, such as stress shielding or implant failure, were found. This is the first case series to describe the use of a custom 3D-printed titanium truss implant to successfully contribute to reconstruction in the setting of failed elective foot and ankle surgery. This technology might play an important role in limb salvage of osseous defects that would otherwise require bone block arthrodesis with structural allograft or autograft bone., (Copyright © 2017 The American College of Foot and Ankle Surgeons.

In 1975, Evans published an article describing the surgical management of the "calcaneo-valgus deformity," pointing out that the deformity was due to relative shortening of the lateral column of the foot. Correction involved "equalizing" both columns by performing an osteotomy in the neck of the calcaneus 1.5 cm from the calcaneocuboid joint, where a trapezoidal wedge of tricortical bone was placed. Although it was considered a success, there were complications, including sural nerve injury, surgical wound dehiscence, undercorrection, and graft subsidence. The osteotomy grew in popularity. Indications extended to other forms of flatfoot with a low incidence of complications., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Pediatric flatfeet are common, are usually asymptomatic, and typically improve over time as young children age. It is critical to differentiate flexible from rigid flatfeet and to assess for associated Achilles contracture with a careful history, physical examination, and initial radiographs. Although there are limited data, nonsurgical management of symptomatic flatfeet, both flexible and rigid, should be exhausted before considering surgical intervention. If patients fail conservative treatment, surgical management with joint-preserving, deformity-corrective techniques is typically used for pediatric flexible flatfeet in conjunction with deformity-specific soft tissue procedures., (Copyright © 2017 Elsevier Inc.

Adult acquired flatfoot deformity is a debilitating condition typically affecting middle-aged patients. The multiple components include hindfoot valgus, first ray elevation, medial soft tissue compromise, and forefoot abduction. As the foot becomes unbalanced, the deformity progresses with repetitive loading and time. Untreated patients often need significant reconstructions or extensive arthrodesis after arthritis and joint contractures present. Medializing calcaneal osteotomy is the workhorse operation for correction of hindfoot valgus, reliably correcting deformity with a relatively low complication risk. This article reviews indications, techniques, complications, and outcomes for the medializing calcaneal osteotomy., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Scarf osteotomy is a common operative procedure for mild-to-moderate hallux valgus.

The Cotton osteotomy or opening wedge medial cuneiform osteotomy is a useful adjunctive flatfoot reconstructive procedure that is rarely performed in isolation. The Cotton procedure is relatively quick to perform and effectively corrects forefoot varus deformity after rearfoot fusion or osteotomy to achieve a rectus forefoot to rearfoot relationship. Proper patient selection is critical, because preoperative findings of medial column joint instability, concomitant hallux valgus deformity, or degenerative joint disease of the medial column might be better treated with arthrodesis of the naviculocuneiform or first tarsometatarsal joints. Procedure indications also include elevatus of the first ray, which can be a primary deformity in hallux limitus, or iatrogenic deformity after base wedge osteotomy in hallux valgus. We present the case of an adolescent patient who underwent flatfoot reconstruction, including Cotton osteotomy for correction of forefoot varus that was accentuated after double heel osteotomy. This case highlights our preferred procedure technique, including the use of a nerve-centric incision design. The use of an oblique dorsal medial incision is primarily intended to minimize the risk of trauma to the medial dorsal cutaneous nerve. At 20 months postoperatively for the right extremity and 12 months postoperatively for the left extremity, sensation remained intact, and the patient had not experienced any postoperative nerve symptoms. The patient had returned to playing sports without pain or restrictions., (Copyright © 2017 American College of Foot and Ankle Surgeons. Published by Elsevier Inc. All rights reserved.)

We report a case using retrograde tibial nailing as treatment of nonunion of a distal tibial osteotomy, which was performed as part of a complex reconstruction of distal tibial malunion with ankle arthritis. Although retrograde nailing has classically been used for tibial-talar-calcaneal arthrodesis, this method spares the subtalar joint. Preservation of some hindfoot motion by subtalar mobility allows for a decrease in the loss of function typically seen with tibial-talar-calcaneal arthrodesis., (Copyright © 2016 American College of Foot and Ankle Surgeons.

The techniques for performing percutaneous osteotomies in treating deformities of the foot in children are presented along with a detailed description of the operative details. The author's use of minimal-access surgery for tibial, os calcis, and midfoot osteotomies is described using a cooled side-cutting burr that has not previously been described for use in the child's foot. The cancellous nature of the bones in the child are easily cut with the burr and the adjacent soft tissues are not damaged. The early experience of the healing times are not impaired and the complications associated with percutaneous scars seem to be negligible., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Osteotomies of the calcaneus are powerful surgical tools, representing a critical component of the surgical reconstruction of pes planus and pes cavus deformity. Modern minimally invasive calcaneal osteotomies can be performed safely with a burr through a lateral incision. Although greater kerf is generated with the burr, the effect is modest, can be minimized, and is compatible with many fixation techniques. A hinged jig renders the procedure more reproducible and accessible., (Copyright © 2016 Elsevier Inc. All rights reserved.)

The percutaneous osteotomy based on a Hohmanntype first metatarsal subcapital linear osteotomy was introduced into Mainland China in the late 1980s. No internal fixation is used for stabilization of the osteotomy, leading unfortunately to unpredictable results. Despite its high acceptance by patients and enthusiasm by surgeons at present, the clinical outcomes of percutaneous surgery have not been promising. The authors have no experience of performing this osteotomy and report only on their management of the complications of this technique and their recommended treatment algorithm., (Copyright © 2016 Elsevier Inc.

Current practice and controversies in UK bunion surgery are discussed. Patients tend to be offered a distally based metatarsal osteotomy, such as a chevron or scarf osteotomy, for mild to moderate symptomatic bunions. Greater deformities are managed with a more extreme scarf, supplemented with a proximal phalangeal osteotomy. A proximal fusion in the form of the Lapidus-type procedure is still reserved for the most severe, hypermobile, or arthritic cases. Minimally invasive techniques for bunions have failed to disseminate into common UK practice. The trends in the United Kingdom regarding litigation, venous thromboembolism, and osteodesis for bunion surgery are also discussed., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Ninety percent of patients with rheumatoid arthritis will display foot and ankle pathologic features, including hallux valgus, lesser metatarsophalangeal (MTP) joint subluxation/dislocation, and hammertoe deformity. Recently, a trend has ensued toward joint preservation with distal metatarsal osteotomies and various bunion corrective procedures. However, the reference standard remains first MTP joint fusion, lesser metatarsal head resection, and lesser proximal interphalangeal joint fusion. The present retrospective study followed the results of 4 different surgeons who had performed the reference standard rheumatoid forefoot reconstruction from August 2008 to August 2012 on patients with rheumatoid arthritis. Radiographic and statistical analysis of the data from 20 patients determined an overall first MTP joint fusion rate of 90%, often occurring by 108 (range 64 to 202) days postoperatively. Radiographic nonunion occurred in 2 of the 20 patients (10%), although both were asymptomatic, with no revision necessary. Lesser digit deformity revision occurred in 1 patient (5%), and mild to moderate infection developed in 4 patients (20%). The radiographic and clinical follow-up period was 12 months. Our study found that this technique provides exceptional radiographic improvement, an acceptable time to fusion, a low reoperation rate, and minimal complications. In addition, correction of the deformity was maintained at 1 year postoperatively. In conclusion, first MTP joint fusion with lesser metatarsal head resection should remain the reference standard for surgical intervention of the rheumatoid foot., (Copyright © 2016 American College of Foot and Ankle Surgeons.

Hallux valgus is one of the most common foot deformities. Proximal opening wedge osteotomy is used for the treatment of moderate and severe hallux valgus with metatarsus primus varus. However, hypermobility of the first tarsometatarsal joint can compromise the results of the operation, and a paucity of midterm results are available regarding proximal open wedge osteotomy surgery. The aim of the present study was to assess the midterm results of proximal open wedge osteotomy in a consecutive series of patients with severe hallux valgus. Thirty-one consecutive adult patients (35 feet) with severe hallux valgus underwent proximal open wedge osteotomy. Twenty patients (35.5%) and 23 feet (34.3%) were available for the final follow-up examination. The mean follow-up duration was 5.8 (range 4.6 to 7.0) years. The radiologic measurements and American Orthopaedic Foot and Ankle Society hallux-metatarsophalangeal-interphalangeal scores were recorded pre- and postoperatively, and subjective questionnaires were completed and foot scan analyses performed at the end of the follow-up period. The mean hallux valgus angle decreased from 38° to 23°, and the mean intermetatarsal angle correction decreased from 17° to 10°. The mean improvement in the American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal-interphalangeal score increased from 52 to 84. Two feet (5.7%) required repeat surgery because of recurrent hallux valgus. No nonunions were identified. Proximal open wedge osteotomy provided satisfactory midterm results in the treatment of severe hallux valgus, with a low complication rate. The potential instability of the first tarsometatarsal joint does not seem to jeopardize the midterm results of the operation., (Copyright © 2016 American College of Foot and Ankle Surgeons.

Forty-seven patients (50 feet) underwent surgical intervention for symptomatic hallux rigidus from February 1998 to April 1999. Thirty-eight patients (41 feet) returned at 1 year for a follow-up evaluation. Of these 38 patients, 20 (21 feet) returned for the 15-year follow-up evaluation. Subjective evaluations were performed using the modified American Orthopaedic Foot and Ankle Surgery hallux metatarsophalangeal-interphalangeal 100-point scale. Long-term postoperative objective physical examination and radiographic analysis were performed. These data were compared with the preoperative and short-term follow-up data. The subjective evaluation showed a statistically significant differing over the long term, with a mean increase of 27.6 points. The results of the physical examination and radiographic measurements were mixed. The long-term dorsal range of motion was not significant across surgery type. Radiographically, the procedure types resulted in similar changes, suggesting that neither joint preservation nor joint destructive procedures were more stable over time. Plantar transposition of the capital fragment, offsetting the longitudinal shortening of the first metatarsal, was not significant, confirming the short-term findings. For this patient population, the long-term results of surgical intervention for hallux rigidus, regardless of procedure type, provided subjective patient improvement but no statistically significant increase in first metatarsophalangeal joint function or dorsal range of motion., (Copyright © 2016 American College of Foot and Ankle Surgeons.

Incomplete reduction of the sesamoid is a known risk factor for recurrence of the deformity after scarf osteotomy for correction of hallux valgus. The purpose of the present study was to determine whether a learning curve exists for successfully restoring the sesamoid position in scarf osteotomy. We reviewed 71 consecutive cases (71 feet) of scarf osteotomy performed on female patients during a 2.5-year period by the same surgeon. The cases were divided into 3 groups according to the date of surgery, with the first 24 cases assigned to group 1, the next 24 to group 2, and the last 23 to group 3. We compared the median sesamoid position of the 3 groups at 6 weeks postoperatively and patient reported satisfaction at 6 months postoperatively. The sesamoid position ranged from 1 to 7, using the Hardy and Clapham classification system. The median sesamoid position for all patients had improved from 7 preoperatively to 2 postoperatively. The postoperative sesamoid position was significantly better for the second and third groups than for the first (p < .05), and 92% of the patients were satisfied with the procedure. We have concluded that a learning curve to optimally restoring the position of the sesamoid in scarf osteotomy is present and that this has a direct effect on reducing the risk of recurrence of the deformity., (Copyright © 2015 American College of Foot and Ankle Surgeons.

Calcaneal osteotomies are used to correct hindfoot alignment. Traditional open procedures have been plagued with complications. Various minimally invasive techniques have been described but are laborious and time-consuming. A percutaneous technique using a side cutting "Shannon" burr offers a simple and reliable alternative; however, little evidence is available to address the safety concerns. The aim of the present study was to quantify the risk posed to the medial and lateral neurovascular structures using this technique. The study was performed at the anatomy department, University of Sussex, using 13 fresh-frozen, below-the-knee cadaveric specimens during a training session held by WG Healthcare UK, Ltd. (Letchworth, Herts). The participants were 11 consultant orthopedic surgeons, who were inexperienced in minimally invasive surgery, and 2 demonstrators. Each performed a chevron calcaneal osteotomy using a Shannon burr by way of a lateral percutaneous approach under fluoroscopic guidance. The authors subsequently dissected the specimens to identify the neurovascular structures, describe their anatomic relations and proximity to the burr, and note any damage incurred. No evidence was found of significant neurovascular injury. Two very small proximal branches of the sural nerve were transected, the nerve itself passing safely 9 to 21 mm anterosuperior to the entry point. The medial neurovascular bundle crossed the path of the osteotomy in 4 specimens but was protected by the medial head of the quadratus plantae muscle. In conclusion, the Shannon burr for calcaneal osteotomy has the potential to minimize the surgical morbidity and maximize surgical efficiency without compromising safety in all patients with normal anatomy of the quadratus plantae muscle., (Copyright © 2015 American College of Foot and Ankle Surgeons.

Determining the status of bone healing after osteotomy can be challenging and has implications ranging from clinical decision-making to standardization of research outcomes without the use of computed tomography. To date, no method has been validated for determining osseous healing of an osteotomy site of the long bones of the foot. The purpose of the present study was to develop a radiographic union scoring system that would enhance the diagnostic healing assessment. We adapted existing orthopedic scales that had been validated for healing in the leg for application in the long bones of the foot. One hundred cases were evaluated by 6 blinded assessors to test the inter- and intrarater reliability of the subjective healing assessment compared with the proposed scoring system. The radiographs were classified by postoperative period: ≤4, 5 to 12, and >12 weeks. The proposed scale had a high interrater reliability but was burdensome. Using a priori item reduction protocols, the scale was limited to the 5 items with the best internal consistency, which significantly reduced the burden. The result was excellent interrater reliability (α = 0.87) among all assessors compared with acceptable reliability (α = 0.66) for the subjective osteotomy healing assessment. The intrarater reliability during the subsequent retest phase demonstrated similar relationships, with low agreement (r = 0.38) for subjective healing. Each of the items included in the final scoring scale had moderate to good agreement across all assessors (r = 0.51 to 0.63). The reliability of this system appeared superior to the subjective assessment of osseous healing alone, even in the absence of clinical correlates after an osteotomy in the foot., (Copyright © 2015 American College of Foot and Ankle Surgeons.

Recurrent metatarsalgia has a multifactorial etiology. The analysis of the cause is critical in planning appropriate treatment. Understanding etiology helps understand the mechanism of prevention, which is the best treatment. Recurrent metatarsalgia is often due to poor technique or poor understanding of the underlying problem. In hallux valgus surgery, recurrent metatarsalgia can be a problem of position of the first metatarsal after an inappropriate or poorly done first metatarsal osteotomy or a problem of gastrocnemius tightness not previously recognized. The best treatment is to restore the normal anatomy but that is not always possible, and surgery on affected rays could be the solution., (Copyright © 2014 Elsevier Inc. All rights reserved.)

The treatment of hallux valgus depends on multiple factors, including clinical examination, patient considerations, clinical findings, radiographic assessment, and surgeon preference. Appropriate procedure selection and proper technique will usually result in good-to-excellent outcomes. Complications following hallux valgus correction include recurrence, transfer metatarsalgia, avascular necrosis, hallux varus, and nonunion and malunion of metatarsal osteotomies. In order to decrease the risks of complication, a precise and meticulous physical examination should be conducted preoperatively. In addition, a surgeon should select appropriate osteotomies to correct complex hallux valgus deformities. As a general principle, the severity of deformity dictates treatment options., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Iatrogenic hallux varus is a relatively rare complication of corrective hallux valgus surgery that has multiple pathologic facets. It requires a comprehensive assessment that focuses on joint flexibility, joint integrity, soft tissue balance, and bony deformity. A step-wise treatment approach is used to address all elements of the deformity. The literature on hallux varus treatments consists mainly of retrospective case series, with several proposed procedures addressing various degrees of deformity. Comparison of these procedures is a challenging endeavor and each case should be considered on an individual basis., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Transfer metatarsalgia is a recognized complication following hallux valgus surgery, usually as a result of shortening of the first metatarsal. In this article, the authors present an overview of the incidence, presentation, and treatment strategies employed in its management., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Metatarsalgia, pain around the metatarsophalangeal joints, may arise from mechanical causes spontaneously or iatrogenically. Nonunion or malunion of the first metatarsal can transfer weight-bearing forces and overload the lesser metatarsals. Transfer metatarsalgia after failed hallux valgus surgery is troublesome and more prevalent than would be expected. Clinical examination of the patient allows identifying the type of transfer metatarsalgia and pathomechanics involved. This review focuses on transfer metatarsalgia after hallux valgus surgery and provides a basic understanding of the pathomechanics, clinical examination, and image studies. It also addresses the options for both conservative and surgical treatment of this challenging condition., (Copyright © 2014 Elsevier Inc. All rights reserved.)

The management of complex wounds remains a challenge, and although there have been many promising advances, patients often undergo a morbid and lengthy process to obtain sufficient, satisfactory healing. Sarcoma patients are especially vulnerable to soft tissue wound-healing complications. These patients are often treated with neoadjuvant radiation and/or chemotherapy and have compromised local vascularity to healing tissue. The advent and refinement of wound vacuum-assisted closure technology have been shown to have a tremendous impact. This article reviews the benefits of some novel technologies currently undergoing investigation in orthopedic oncology that will likely have applications in wound management from other causes., (Copyright © 2014 Elsevier Inc.

Acute arterial insufficiency after revision hallux valgus surgery is a rare complication. The identification of surgical candidates who are at risk of vascular complications is of utmost importance. The patient-reported symptoms and physical findings combined with noninvasive vascular studies are generally reliable to assess the vascular status but can fail to identify patients with atypical disease patterns. We present the case of a patient with normal pulses who underwent revision hallux valgus surgery, leading to gangrene of the hallux that required transmetatarsal amputation. We reviewed the vascular evaluation methods and causes of acute ischemia after surgery, including vasculitis., (Copyright © 2013 American College of Foot and Ankle Surgeons.

The present retrospective investigation aimed to determine the factors associated with recurrence of hallux valgus deformity after scarf osteotomy in 50 feet in 43 consecutive patients. We hypothesized that hallux abductovalgus after scarf osteotomy recurs because of the presence of preoperative joint incongruity. The clinical and radiographic findings, including the weightbearing radiographic hallux valgus angle, first intermetatarsal angle, distal metatarsal articular angle, first metatarsophalangeal joint congruence, American Orthopaedic Foot and Ankle Society scores, and pain measured on a visual analog scale, and logistic regression analysis were used to analyze the association of the independent variables with the recurrence of deformity. The mean age of the patients was 47.7 (range 21 to 65) years, and the mean follow-up duration was 26.2 (range 18 to 36) months. The mean American Orthopaedic Foot and Ankle Society scores improved from 50.7 ± 4.9 to 88.7 ± 7.9, and the visual analog scale pain scores improved from 7.5 ± 1.1 to 2.4 ± 1.0 (p < .05). The changes in the radiographic measurements were also statistically significant. Of the 50 feet, 5 (10%) developed recurrent hallux abductovalgus, each of which occurred in feet that had displayed a first metatarsophalangeal joint incongruity on preoperative radiographs. The incongruity was observed to be a statistically significant risk factor for recurrence according to the regression models. From our experience with the patients analyzed in the present report, we believe that first metatarsophalangeal joint congruity should be given particular attention when surgical correction of hallux abductovalgus is undertaken., (Copyright © 2013 American College of Foot and Ankle Surgeons.

A varus or valgus talar tilt that increases under weight-bearing is commonly seen in osteoarthritic ankles. Loss of peritalar stability may be the underlying cause for the talus shifting and rotating on the calcaneonavicular surfaces, as given by applied forces. The instability pattern and the resulting deformity can be assessed and classified using weight-bearing conventional radiographs. Appropriate osseous balancing may be the most appropriate treatment to restore a regular position of talus within the ankle mortise. In cases with severe peritalar instability, subtalar fusion may be advised. Soft tissue reconstruction may be needed to achieve physiologic balance of the hindfoot complex., (Copyright © 2013 Elsevier Inc. All rights reserved.)

The Evans lateral column lengthening procedure allows correction of abduction, improved talar head coverage, decreased forefoot and rearfoot valgus, and improvement of medial column arch height. However, identifying the structures at risk when performing this osteotomy has proved difficult in vivo. Using 10 cadaveric lower limbs, we performed the Evans calcaneal osteotomy and determined whether violation of the calcaneal facets and the sustentaculum tali occurred. Based on our findings, we recommend directing the osteotomy from posterolateral to anteromedial., (Copyright © 2013 American College of Foot and Ankle Surgeons. Published by Elsevier Inc.
