Purpose The purposes of this study were to determine the incidence of anterior shoulder pain in young athletes undergoing arthroscopic posterior labral repair for symptomatic unidirectional posterior shoulder instability and in patients with preoperative anterior shoulder pain treated without biceps tenodesis at the time of arthroscopic posterior labral repair who underwent a revision biceps tenodesis procedure at short-term follow up. Methods A retrospective review was performed at a single institution over a 24-month period. The study included young patients who underwent an arthroscopic posterior labral repair for symptomatic unidirectional posterior shoulder instability. The electronic medical record, magnetic resonance arthrograms, and arthroscopic images were reviewed to exclude patients with posterior labral tears with anterior labral tear or SLAP (superior labrum anterior-to-posterior) tear extension on advanced imaging and arthroscopic examination. Data collected included the presence of preoperative tenderness to palpation of the biceps tendon in the groove, the results of a preoperative Speed test, postoperative Subjective Shoulder Value, the presence of postoperative anterior shoulder pain, and the need for a secondary biceps tenodesis. Results We identified 65 patients who underwent arthroscopic labral repair for posterior shoulder instability. From this cohort, 26 patients with symptomatic unidirectional posterior shoulder instability underwent an arthroscopic posterior labral repair. The incidence of preoperative anterior shoulder pain with Zone 2 biceps groove tenderness and a positive Speed test was identified in 20 of 26 patients (76.9%). Of 26 patients, 5 (19%) had concomitant biceps tenodesis. The median postoperative Subjective Shoulder Value was 80 (interquartile range, 60-90) at median follow-up of 2.1 years. Of the 20 patients with preoperative anterior shoulder pain, 8 of 20 (40%) reported persistent anterior pain. One patient (4.7%) underwent a secondary biceps tenodesis. Conclusions There is a high incidence of anterior shoulder pain and Zone 2 biceps groove tenderness in patients undergoing isolated arthroscopic posterior labral repair for unidirectional posterior shoulder instability. At short-term follow-up, few patients required a secondary biceps tenodesis procedure; however, 30% of patients had persistent anterior shoulder pain.

Objectives To characterize the fracture pattern and pattern of fragmentation for displaced, midshaft clavicle fractures undergoing operative management. Design Prospective observational study. Setting Two institutions. Level 1 and Level 2 Trauma Centers. Patients/participants Fifty-three patients who underwent operative repair of midshaft clavicle fracture. Intervention All clavicles were treated by operative open reduction internal fixation. Main outcome measurements All clavicles were categorized by the Robinson classification based on injury plain film bilateral upright clavicle radiographs. In addition, intraoperative fracture characteristics of fragment length and location were measured and recorded to evaluate the fracture pattern. All fractures were analyzed to determine the frequency of segmental comminution versus length-stable patterns, analyze characteristics of butterfly fragment size, number and location as well as the location of the cortical read for those length-stable fractures. Results Analysis revealed 55% were Robinson 2B2 based on preoperative radiographs. Length-stable, anatomic reduction was achievable in 83%. For those in which an anatomic cortical read was achievable, 97.7% had a read present in the posterior-superior aspect of the clavicle. Conclusions Midshaft clavicle fractures that meet conventional criteria for operative repair occur in a predictable manner with butterfly fragments generated from anterior-inferior compression and simple fracture line generated from tension along the posterior-superior aspect of the clavicle. Understanding this pattern can assist in the in surgical planning.

Recent literature recommends consideration of surgical treatment for completely displaced and shortened middle-third clavicle fractures. Intramedullary clavicle fracture fixation has been shown to be an effective option for treatment. While traditional plate constructs have been successful, hardware removal due to symptomatic prominence has been reported. Intramedullary fixation offers a lower profile solution, which can be performed through a smaller incision.

Orthopaedic advancements into the 21st century will increasingly focus on chondral restoration to either halt or reverse degenerative processes. Researchers and clinicians will need tools beyond patient-reported outcomes to measure the effectiveness of these treatment efforts. The use of joint space width (JSW) as a surrogate for chondral restoration is inadequate. At a minimum, such observations must standardize load transmission across the joint to be useful. Simple, readily available, standardized, and clinically useful measures of knee chondral restoration would facilitate and accelerate advances in the field. For now, it may be that improvement in JSW after chondral restoration could be attributable to changes in mechanical alignment of the knee and not the chondral restoration. JSW is an inadequate surrogate for chondral restoration, and anyone doing a stress radiograph of a unicompartmental degenerative knee recognizes this point.

Background Arthroscopic examination of the tendon has been described as the “gold standard” for diagnosis of tendinitis of the long head of the biceps (LHB). An arthroscopic finding of an inflamed and hyperemic LHB within the bicipital groove has been described as the “lipstick sign.” Studies evaluating direct visualization in diagnosis of LHB tendinitis are lacking. Methods During a 1-year period, 363 arthroscopic shoulder procedures were performed, with 16 and 39 patients prospectively selected as positive cases and negative controls, respectively. All positive controls had groove tenderness, positive Speed maneuver, and diagnostic ultrasound-guided bicipital injection. Negative controls had none of these findings. Six surgeons reviewed randomized deidentified arthroscopic pictures of enrolled patients The surgeons were asked whether the images demonstrated LHB tendinitis and if the lipstick sign was present. Results Overall sensitivity and specificity were 49% and 66%, respectively, for detecting LHB tendinitis and 64% and 31%, respectively, for erythema. The nonweighted κ score for interobserver reliability ranged from 0.042 to 0.419 (mean, 0.215 ± 0.116) for tendinitis and from 0.486 to 0.835 (mean, 0.680 ± 0.102) for erythema. The nonweighted κ score for intraobserver reliability ranged from 0.264 to 0.854 (mean, 0.615) for tendinitis and from 0.641 to 0.951 (mean, 0.783) for erythema. Conclusions The presence of the lipstick sign performed only moderately well in a rigorously designed level III study to evaluate its sensitivity and specificity. There is only fair agreement among participating surgeons in diagnosing LHB tendinitis arthroscopically. Consequently, LHB tendinitis requiring tenodesis remains a clinical diagnosis that should be made before arthroscopic examination.

Introduction Resilience is a psychometric construct of a patient’s ability to recover from adversity and has been used to predict outcomes but its use in orthopedics has been limited. The purpose of this study was to examine the association between resilience and outcomes. Materials and Methods We performed a retrospective analysis of prospectively collected data of patient who underwent sports knee surgery at a single institution performed by 6 orthopedic surgeons from January 2017 to December 2017. We included active-duty patients with complete preoperative outcomes and a minimum of 6 month follow-up. All patients completed the Brief Resilience Scale (BRS), Veteran’s Rand-12 (VR-12), Patient-Reported Outcomes Measurement Information System 43 (PROMIS-43), International Knee Documentation Committee function score (IKDC), and Knee Injury and Osteoarthritis Outcome Score (KOOS). Patients were divided into low resilience (LR) and high resilience (HR) groups based on a score of less than 24 for low and greater than or equal to 24 according to BRS. Outcomes were then compared. Results We identified 50 active-duty patients who had complete preoperative and postoperative outcomes at a minimum of 6 months. Mean preoperative and postoperative BRS were significantly different (25.8 HR v 18.6 LR, p < 0.001). We found a difference in postop KOOS in pain, sports, and short form (pain 70.9 HR v 55.7 LR, p = 0.03; sports 50.3 HR v 32.2 LR, p = 0.03; short form (72.1 HR v 62.5 LR, p = 0.04). Similarly, there was a significant difference in postoperative IKDC score (58.0 HR v 44.0 LR, p = 0.03). Similarly we found significant differences in postoperative PROMIS-43 (anxiety 44.4 HR v 60.3 LR, p = 0.004; depression 41.6 HR v 58.1 LR, p = 0.004; fatigue 45.1 HR v 58.6 LR, p = 0.001; sleep 52.6 HR v 62.5 LR, p = 0.02; social participation 36.2 HR v 47.6 LR, p < 0.001). Postoperative VR-12 mental was also statistically different between the two groups (53.5 HR v 41.6 LR; p = 0.01). In addition, 2.3% of the HR group changed MOS as a result of their sports knee surgery compared to 22.2% of the LR group. Conclusions Active-military patients with high preoperative resilience appear to have significantly better early postoperative outcomes following sports knee surgery in terms of PROMIS-43, KOOS, and IKDC. There was also a lower rate of changing MOS secondary to sports knee surgery in patients with high resilience.

Meniscal injury is a common knee injury in a young athletic population. Maintaining the integrity of the meniscus is critical to reducing contact pressures on the tibiofemoral articulation. The purpose of this study is to analyze the outcomes of meniscal repair in a young military population. We conducted a retrospective review of all meniscal repairs performed on active duty Army personnel at a Military Medical Center from January 2002 to December 2012. One hundred seventy-eight active duty patients, mean age 28 (19-48) years underwent 178 meniscal repairs. Postoperatively, 33 (18.5%) patients were medically separated from the military at an average time of 29 months. Fifty (28%) patients required a permanent duty restricting profile. Ninety-five (53.5%) patients required no profile after meniscal repair at an average follow-up of 5 (1.5-12.3) years. Meniscal repair in this young military population allowed 81.5% of patients to return to duty; however, 34% of those required a permanent duty restricting profile. Approximately 20% of patients required medical separation from the military after meniscal repair. Older age was significantly associated with the ability to remain on active duty (p = 0.01).

Background Middle-third clavicle fractures represent 2% to 4% of all skeletal trauma in the United States. Treatment options include intramedullary (IM) as well as plate and screw (PS) constructs. The purpose of this study was to analyze the biomechanical stability of a specific IM system compared with nonlocking PS fixation under low-threshold physiologic load. Methods Twenty fourth-generation Sawbones (Pacific Research Laboratories, Vashon, WA, USA) with a simulated middle-third fracture pattern were repaired with either an IM device (n = 10) or superiorly positioned nonlocking PS construct (n = 10). Loads were modeled to simulate physiologic load. Combined axial compression and torsion forces were sequentially increased until failure. Data were analyzed on the basis of loss of rotational stability using 3 criteria: early (10°), clinical (30°), and terminal (120°). Results No significant difference was noted between constructs in early loss of rotational stability (P > .05). The PS group was significantly more rotationally stable than the IM group on the basis of clinical and terminal criteria (P Conclusions When tested under physiologic load, fixation failure occurred from loss of rotational stability. No statistical difference was seen between groups under early physiologic loads. However, during load to failure, the PS group was statistically more rotationally stable than the IM group. Given the clavicle's function as a bony strut for the upper extremity and the biomechanical results demonstrated, rotational stability should be carefully considered during surgical planning and postoperative advancement of activity in patients undergoing operative fixation of middle-third clavicle fractures.

Acromioclavicular separations are common injuries. Low-grade separations are typically managed with nonoperative treatment. However, surgical treatment is recommended for high-grade separations, as well as for chronic low-grade separations that remain symptomatic. Multiple fixation techniques have been described over the past several decades, including Kirschner wires, hook plates, and coracoclavicular screws. More recently, a single-tunnel suture-graft repair and an anatomic reconstruction reproducing both the conoid and trapezoid ligaments have been described. All described techniques have reported complications, including implant migration, need for implant removal, clavicle or coracoid fracture, and loss of reduction. As a result, there is no single optimal method of operative fixation. We describe our technique for an arthroscopically assisted anatomic coracoclavicular repair using a 6-strand suture tape and cortical button construct.

The purpose of this study is to determine the prevalence of potential graft-influencing pathologies of the extensor mechanism of the knee in patients presenting with a primary anterior cruciate ligament (ACL) rupture. We performed a retrospective review of the plain radiographs and magnetic resonance imaging (MRI) of all active-duty patients presenting with a primary ACL rupture at our institution between July 2006 and February 2009. Imaging was reviewed to determine the presence of a multipartite patella, unresolved Osgood-Schlatter's disease, and/or radiographic evidence suggestive of patella tendinopathy. A total of 197 patients were reviewed, including 27 females and 170 males. One patient (0.5%) had a bipartite patella and 4 patients (2%) had free-floating ossicles about the tibial tuberosity consistent with unresolved Osgood-Schlatter's disease. A total of 15 patients (7.6%) showed MRI evidence suggestive of patella tendinopathy. This study revealed 20 patients out of 197 (10.1%) who presented with existing extensor mechanism pathologies in radiologic studies. While preoperative imaging is routinely used to confirm clinical suspicion of ACL rupture or identify associated injuries, this study shows that it can also identify existing extensor mechanism pathologies that could ultimately influence the use of an extensor mechanism graft.

Pectoralis major rupture is an uncommon injury often treated surgically, requiring anatomic knowledge of the tendon insertion. This study defines the pectoralis major tendon insertion footprint and a novel anatomic relationship. Twelve cadaver shoulders were evaluated andmeasured using a standard surgical ruler to demonstrate the normal anatomic footprint. Measurements were taken from the anterior medial margin of the articular surface of the humeral head to the superior margin of the pectoralis major insertion and its relation to the latissimus dorsi tendon insertion. The average length and width of the pectoralis major insertion were 73.3 ± 10.0 mm and 3.3 ± 0.54 mm, respectively, consistent with previous publications. On average, the superior margin of the pectoralis tendon was within 1 mm of the latissimus dorsi insertion and 41.2 ± 9.27 mm from the articular margin. These points form a new anatomic reference of the latissimus dorsi, providing an intraoperative reference point when performing pectoralis major muscle tendon repair.

OBJECTIVE: To evaluate the accuracy of radiographs in determining integrity of the posterior femoral cortex following ACL reconstruction. METHODS: Fifty adult volunteers undergoing primary arthroscopic transtibial ACL reconstructions were prospectively enrolled into this study. Plain radiographs and fine-cut CT of the operative knee were obtained post-operatively. Three blinded orthopaedic surgeons were asked to measure the distance from the femoral tunnel to the posterior cortex on lateral radiographs. Inter/intra-observer reliabilities were assessed with the interclass correlation coefficient. The true measurement of the posterior wall was determined on CT. For each, a measurement was made at the aperture, 5 mm, and 10 mm along the tunnel. Plain radiographic measurements were compared to the CT measurement of back wall using a paired t-test. RESULTS: All measurements made on the lateral radiograph were significantly different from those from the respective CT scans for each surgeon (p

Missile emboli from bullets occur infrequently, with the first reported case appearing in 18341. At least 160 reports of this phenomenon exist in the literature2. A variety of missile emboli, including arterioarterial as well as aortoarterial emboli, have been reported, with up to two-thirds causing peripheral ischemia3. The patient discussed in this case report initially had no symptoms in the affected right extremity. This may be common; less than one-third of missile emboli initially are symptomatic3. The patient was informed that data concerning the case would be submitted for publication, and he provided consent. A forty-year-old U.S. soldier was performing combat operations in Afghanistan when a 2000-pound Joint Direct Attack Munition aerial fragmentation bomb impacted approximately 100 yards away from his position. He sustained multiple fragment wounds to the left leg, the left flank and back, and the right wrist and hand. He was initially stable and was evacuated from Afghanistan to Seeb Air Base Hospital in Oman, with a transport time of approximately six hours. The only prehospital treatment he received was placement of an intravenous line (IV) in the right antecubital fossa. Upon arrival at the hospital, the only symptom was right upper-extremity pain from the elbow distally, which had started after the IV had been placed. On physical examination, he had spontaneous air entry with diminished breath sounds on the left side. There were multiple wounds smaller than 5 mm over the left leg, left flank and back, and the right wrist and hand. There was a sizeable wound approximately 1 cm in diameter on the left posterior thorax (Fig. 1). All limbs were perfused with brisk …

To determine the infection rate of intramedullary (IM) nailing of closed diaphyseal femur fractures after temporary stabilization with external fixation in an austere combat environment.Retrospective case series.Iraq and Afghanistan Theater and Military Medical Treatment Centers in the United States and Landstuhl, Germany.Military personnel who underwent temporizing external fixation of a closed diaphyseal femur fracture (OTA 32) with later conversion to an IM nail between 2003 and 2012.Patients were identified from the Joint Theater Trauma Registry and Department of Defense electronic medical record, and a retrospective review was performed.Variables measured included age, gender, mechanism of injury, Injury Severity Score, associated injuries (to include thoracic and abdominal injuries), base deficit, history of massive transfusion, date of injury, date and place of external and IM fixations, time to conversion procedure, report of superficial or deep infection, report of fracture union, and date of last follow-up.One hundred twenty-two patients, mean age 25 (18-43) years, sustained 125 closed femoral diaphyseal fractures from May 2003 to July 2012. External fixation was performed at a mean of 0.2 days (median of the day of injury) and a range of 0-3 days. Mean time to IM nail conversion procedure was 6.9 (1-20) days. Infection rate was 2.5%, with a P of 0.188. Average follow-up was 41.4 (12-119) months.Acceptable low infection rates can be achieved after IM nailing of closed diaphyseal femur fractures treated with initial external fixation in an austere combat environment.Therapeutic Level IV.

Purpose The purpose of this study was to determine the incidence of meniscal injury, specifically medial meniscal injury, in US Army soldiers undergoing revision anterior cruciate ligament (ACL) reconstruction. Methods A retrospective review was performed of all patients who underwent revision ACL reconstruction from 2002 to 2011 at our institution. A complete chart review was performed to identify the prevalence of meniscal pathology identified at the time of revision ACL surgery. Patient demographic data and meniscal injury patterns were analyzed. Results Sixty-seven patients were identified, with a mean age of 28 years. The mean time to revision reconstruction was 67 months. Most patients (64.1%) reported a distinct reinjury. Reinjury was reported as the cause for revision ACL reconstruction in 43 patients. In this subgroup the mean time from reinjury to revision surgery was 13.9 months. Meniscal pathology was identified in 50 patients (74.6%). Medial meniscal tears were noted in 38 patients (56.7%), a rate significantly greater than that previously described ( P = .008). Lateral meniscal tears were noted in 26 patients (38.8%), which was similar to previously published data ( P = .52). Conclusions The prevalence of meniscal injury at the time of revision ACL reconstruction in active-duty US Army soldiers is nearly identical to that of previously published data looking at a civilian population (74.6% v 74%) in the Multicenter ACL Revision Study (MARS) cohort. However, the incidence of medial meniscal injury was greater in the active-duty population than in the civilian population (56.7% v 40%). The observed increase in the prevalence of medial meniscal pathology is likely multifactorial, relating to the unique demands on young military athletes in both combat and training environments, rate of reinjury, and various delays to treatment after reinjury.

Proximal humerus fracture after pectoralis major tendon repair has been recently reported. Although this complication is rare, it may be possible to decrease such risk using newer techniques for myotenodesis. This study was designed to evaluate various unicortical stress risers created at the proximal humeral metadiaphysis during myotenodesis for repair of pectoralis major ruptures. A simulated pectoralis major myotenodesis was performed using fourth-generation Sawbones (N=30). Using previously described anatomic landmarks for the tendinous insertion, 3 repair techniques were compared: bone trough, tenodesis screws, and suture anchors (N=10 each). Combined compression and torsional load was sequentially increased until failure. Linear and rotational displacement data were collected. The average number of cycles before reaching terminal failure was 383 for the bone trough group, 658 for the tenodesis group, and 832 for the suture anchor group. Both the tenodesis and the suture anchor groups were significantly more resistant to fracture than the bone trough group ( P P Orthopedics. 2017; 40(5):e801–e805.]

Disorders of the spine are a substantial burden to the military health care system that degrades readiness in the overall force. Because treatment outcomes are affected by psychosocial factors, assessment of psychological distress is important for patients with spine complaints. The incidence of psychological distress in the unique military population is not well described. The purpose of this retrospective case-control study was to determine the rate of psychological distress and identify associated patient characteristics among many variables collected in the military health system. A consecutive cohort of active duty service members presenting to a spine specialty clinic was assessed as Normal, At Risk, or Distressed using the Distress and Risk Assessment Method. Of 74 active duty patients (63 male, 11 female), 43 (58%) had some level of psychological distress: 29 (39%) At Risk, 12 (16%) Distressed-Depressive, and 2 (3%) Distressed-Somatic. Multivariate regression analysis identified female gender (odds ratio [OR] 7.90), higher disability as measured by Oswestry Disability Index/Neck Disability Index (OR 8.0 per 13.8 point increase), and assignment to a Warrior Transition Unit or Medical Evaluation Board (OR 7.35) as statistically significant variables. The results indicate that active duty patients are subject to similarly high levels of psychological distress as their civilian counterparts.

Hypothesis The objective of this study was to compare the efficacy of subacromial injection of triamcinolone compared to injection of ketorolac in the treatment of external shoulder impingement syndrome. Methods Thirty-two patients diagnosed with external shoulder impingement syndrome were included in this double-blinded randomized controlled clinical trial. Each patient was randomized into the steroid group or nonsteroidal anti-inflammatory drugs (NSAID) group. The steroid syringe contained 40 mg triamcinolone; and the NSAID syringe contained 60 mg ketorolac. Each patient was evaluated in terms of arc of motion, visual analog scale (VAS) for evaluating pain, and the UCLA (The University of California at Los Angeles) shoulder rating scale. Results At 1 month follow-up, both treatment arms resulted in increased range of motion and decreased pain. The steroid group decreased in active abduction while the NSAID group increased (steroid: 134°, NSAID: 151°, P = .03). The mean improvement in the UCLA shoulder rating scale at 4 weeks was 7.15 for the NSAID group and 2.13 for the steroid group ( P = .03). Subgroup analysis of the UCLA scale demonstrated an increase in both forward flexion strength ( P = .04) and patient satisfaction ( P = .03) in the NSAID group. No significant difference could be seen in all other outcome measures. Conclusion In this study, an injection of ketorolac resulted in greater improvements in the UCLA shoulder rating scale than an injection of triamcinolone at 4 weeks follow-up. While both triamcinolone and ketorolac are effective in the treatment of isolated subacromial impingement, ketorolac appears to have equivalent if not superior efficacy; all the while decreasing patient exposure to the potential side-effects of corticosteroids.

Septic arthritis following anterior cruciate ligament (ACL) reconstruction is an uncommon but potentially serious complication. The incidence of infection is approximately 0.44%. Staphylococcus and streptococcus strains are the most common infectious pathogens. Infection is typically via direct inoculation. Articular cartilage damage is primarily the result of the unregulated host inflammatory response. The timing of presentation is typically

Over 220 U.S. Army orthopaedic surgeons have deployed during the Global War on Terrorism (GWOT). This study documents the orthopaedic procedures performed during the GWOT and identifies training that prepared surgeons for deployment. It reveals deficiencies in surgeons' preparedness and intends to improve predeployment training. All surgeons deployed during the GWOT from 2001 to 2007 were surveyed. Questions fit 4 general categories: deployment demographics, medical and surgical experiences, predeployment preparation, and self-perceived preparedness during deployment. Response rate was 70%. Surgeons averaged 138 adult operative cases and 26 pediatric cases per deployment. All surgeons performed irrigation and debridement, 94% external fixation, 93% amputations, 89% arthrotomies, 86% open reduction and internal fixation, and 76% soft-tissue coverage procedures. Residency and fellowship contributed most to surgeon preparedness for deployment. Surgeons generally reported high levels of preparedness, but nearly 1 in 6 reported low levels of medical, surgical and physical preparedness. More reported low levels of mental preparedness. Soft-tissue coverage was the most frequently reported surgical deficiency. This study documents the number and types of orthopaedic procedures performed during the GWOT and identifies the self-perceived preparedness deficiencies of surgeons in a combat environment. Improvements in predeployment training are needed to better prepare surgeons for managing battlefield causalities.

We performed a retrospective review of elective orthopedic surgeries performed at our institution in 2008. Surgical wait time was defined as the interval between when surgery was offered and when it was performed. Data were available for 1,120 patients and included date and type of procedure, patient age, American Society of Anesthesia (ASA) category, and military rank. Mean wait time for all procedures was 69.1 days. Significant differences were found with regard to patient age, ASA class, rank, and type of procedure. Older patients with higher ASA had significantly longer wait times. Enlisted soldiers had the shortest wait times and retirees the longest. Total joint procedures had the longest wait time (mean 140 days) and the highest anesthesia class. Elective trauma procedures had the shortest wait time (mean 27.2 days). Sports procedures accounted for 46.3% of all cases reviewed. In our cohort, older patients with higher ASA class and those undergoing a total joint procedure can expect longer preoperative wait times. No preferential care given to officers, as enlisted soldiers had the shortest wait times. At our military medical center, which closely models a managed care system, patients can expect to wait more than 2 months for elective orthopedic surgeries.

BACKGROUND: Most pediatric distal radius fractures are treated with closed methods, however, in recent years an increasing number of fractures are treated with operative management. Multiple reduction techniques are described in the orthopaedic literature but no recent advances have been made in the closed management of these injuries. We describe the efficacy of new, single-provider manual reduction technique that improves reduction efficacy and we separately show its biomechanical superiority to other common techniques. METHODS: Review the results of a new reduction technique, known as the Lower Extremity-aided Fracture Reduction (LEAFR) maneuver, used on a specific cohort of consecutively treated patients at a single institution over a 4-year period with bayoneted distal radius fractures. Intention-to-treat methodology and descriptive statistics are utilized to analyze accuracy of reduction, need for operative intervention, residual deformity, and complications. In addition, perform a biomechanical comparison between the LEAFR maneuver, the 2 person traction counter-traction method and finger traps. RESULTS: The technique allowed 24 consecutively treated, bayoneted distal radius fractures to be reduced from average translational and shortening deformities of 11.4 and 6.5 mm to 2.1 and 0.4 mm, respectively (P

We present a series of distal clavicle fractures in which the coracoclavicular ligaments remain intact to the proximal segment, but the distal aspect of the clavicle is displaced superiorly. The fractures sustained in this series are not described in any of the multiple classification systems currently in use for clavicular fractures. We present a series of 2 active-duty patients who sustained nearly identical distal clavicle fractures during Army combatives training. A 23-year-old male was treated successfully with nonoperative therapy and returned to deployment within 2 months. A 23-year-old female failed nonoperative treatment and was successfully treated with an operative open distal clavicle resection. This rare fracture attributed to a specific mechanism of injury has a potential to be commonly encountered in active-duty patients taking part in mandatory combatives programs.

Objective: This is the first report of successful allograft mosaicplasty treatment of a large osteochondral lesion of the knee caused by a blast fragment sustained during combat operations. The patient was able to return to active duty following rehabilitation. Methods: An active-duty infantryman sustained an osteochondral lesion of the medial femoral condyle caused by a metallic fragment of an explosively formed projectile. Initial treatment consisted of removal of the foreign body and primary closure. The patient continued to experience pain, mechanical symptoms, and repeated effusions after initial nonoperative treatment. Allograft mosaicplasty of the lesion utilizing two 18-mm-diameter fresh allograft osteochondral plugs was performed at 6 months post-injury. Results: At 2-year follow-up, the patient remains on active duty with marked improvement in symptoms. Two years postoperatively, his outcome scores are 72 of 100 on the Western Ontario and McMaster University osteoarthritis scoring index (WOMAC) and 60 of 100 on the Knee Injury and Osteoarthritis Outcome Score (KOOS). His follow-up x-rays and MRI demonstrate intact articular cartilage and subchondral bone incorporation. Conclusion: Penetrating injuries to joints are commonplace in the battlefield environment. Combat injuries to the knee are frequently associated with articular cartilage injury. While numerous cartilage restoration techniques have been used with success for the treatment of osteochondral injuries to the femoral condyles, no published reports describe the use of allograft mosaicplasty in this location for open, penetrating injuries with focal cartilage loss. This is the first documented use of allograft mosaicplasty for a traumatic osteochondral defect of the medial femoral condyle caused by a metallic projectile. The patient was able to return to active duty following rehabilitation. We demonstrate a high level of functioning is possible following allograft mosaicplasty of a large osteochondral lesion caused by penetrating ballistic trauma.

Background: Anterior cruciate ligament (ACL) reconstruction is uncommonly complicated by postoperative infections, the causes of which are rarely identified. Hypothesis/Purpose: The goal of this study was to characterize the relationship between methodological sterilization failure and ACL reconstruction infection at an army medical center. Study Design: Case series. Methods: Demographic, clinical, and laboratory data were collected on 5 postoperative infections during a 14-week period in 2003. All ACL reconstructions completed within the past 6 years at the institution were reviewed to establish a baseline infection rate. Results: There was a 14-week period in which 5 cases of infection occurred postoperatively, an infection rate of 12.2%. Previous and subsequent to the identified period, the established rate of infection after ACL reconstruction was 0.3%. There were no violations of sterile technique noted in any of the identified cases. All cases utilized hamstring autograft. All cases also used the DePuy Mitek Intrafix system for tibial fixation of the graft. Two of these cases had positive cultures. Conclusions: An isolated series of increased infection rate led to an investigation into the sterile technique. This revealed gross biomaterial remaining inside instrumentation common to all the cases, the DePuy Mitek Intrafix system. The modular cannulated hex driver, made to fit over a small caliber wire, had no wire brushes of a small-enough diameter for the cleaning and sterilization procedure. After recognition of infection, all patients were treated with surgical irrigation and debridement of the affected knee, as well as individualized antibiotic therapy. Patients were followed postoperatively and no patients required revision ACL reconstruction or radical debridement of the graft.

We report a case of knee pyarthrosis in a 54-year-old woman with rheumatoid arthritis and a popliteal cyst. The onset of infection coincided with a cortisone injection. Initial management consisted of arthroscopic irrigation and debridement (I&D) on 2 consecutive occasions without resolution of the infection. Only after open excision of the popliteal cyst in conjunction with I&D of the knee joint proper did the infection resolve. This is the first reported case of a patient requiring excision of a popliteal cyst to clear pyarthrosis of the knee after failure of arthroscopic I&D. Consideration should be given to open debridement or drainage of popliteal cysts in patients who present with septic arthritis in the presence of a popliteal cyst. A treatment algorithm for managing this clinical scenario is presented.

Background Forward Surgical Teams (FSTs) are 20-person units designed to perform front-line, life-saving combat surgery. This study compares the employment, injuries encountered, and workload of an airborne FST in two widely varying campaigns. Methods The 250th FST provided far forward surgery for initial entry assaults and follow-on stability operations in Afghanistan (Operation Enduring Freedom [OEF]) and northern Iraq (Operation Iraqi Freedom [OIF]). Prospective data on all patients admitted to the 250th were analyzed. Data from civil affairs missions were evaluated retrospectively. Results In supporting combat operations, 127 surgical procedures (OEF: 68, OIF: 59) were performed on 98 patients (OEF: 50, OIF: 48) during 17 months deployed (OEF: 6, OIF: 11). After initial assaults, stability actions varied significantly in terms of civil affairs missions (OEF: 3, OIF: 161). Conclusions Although the number and types of combat casualties were similar between the campaigns, employment of the FST changed dramatically in OIF because of increased medical reconstruction missions.

Purpose Forward Surgical Teams (FST) deploy to support conventional combat units of at least regimental size. This report examines the injuries and treatments of an FST in an environment of unconventional tactics, limited personal protection, and extended areas of responsibility during Operation ENDURING FREEDOM. Methods A prospective evaluation of the personal protective measures, mechanisms of injury, types of injuries, and times to treatment in Operation ENDURING FREEDOM. Additionally, per-surgeon caseloads, operative interventions, and outcomes are examined. The first phase of this deployment involved co-locating with an Air Force Expeditionary Medical Squadron at Seeb Air Base, Oman (SABO). The second phase involved stand-alone operations at Kandahar International Airport (KIA). Participants include U.S. Special Forces, conventional U.S forces, coalition country special forces, and anti-Taliban Afghan soldiers. RESULTS: During the deployment, the FST performed 68 surgical procedures on 50 patients (19 SAB, 31 KIA). There were 35 orthopedic cases (2 to 28 per surgeon), 30 general surgery cases (2 to 10 per surgeon), and 3 head/neck cases. Mechanism of injury included non-battle injury (13), bomb blast (13), gunshot wounds (8), mine (8), and grenades (5). Primary injuries were to the extremities in 27, torso in 9, and head/neck in 11. Three patients had appendicitis. Five patients were wearing body armor, whereas 4 wore helmets. The mean Relative Trauma Score was 7.4. Thirty-one patients were treated at KIA with a mean time to operative treatment of 2.7 ± 2.7 hours, whereas 19 were treated in SABO with a mean time to operative treatment of 12.4 ± 15.1 hours. Nine patients received transfusions. Three nonoperative patients died of wounds. Conclusion Despite the lack of personal protective gear, most patients had extremity wounds as their primary injuries. In this special operations environment, time to operative treatment was significantly longer than expected.

The range of open and arthroscopic shoulder procedures continues to evolve and expand. Despite advances in instrumentation and technology, complications still exist and neurologic injury remains an inherent part of these procedures. Iatrogenic nerve injuries are among the more commonly cited complications associated with shoulder surgery. Various surgical procedures about the shoulder are known to place the brachial plexus and peripheral motor nerves at risk. Peripheral nerve monitoring has been helpful in identifying specific surgical steps and key anatomic regions that are susceptible to iatrogenic nerve injury.

This case documents the care of a 22-year-old deployed male, active duty U.S. Army soldier who was referred to a forward surgical team for a “palpable foreign body” in his left posterior arm. The evening prior, his unit had been dispatched to control what was thought to be enemy activity in the city, due to reported multiple instances of gunfire. This soldier, with his unit, arrived on the scene in a small town in Iraq to investigate the situation. Upon arrival, the unit found that the gunfire was celebratory. The citizens of the city were firing weapons into the night sky in celebration of the capture and death of Saddam Hussein's sons. There was no direct gunfire targeted at the soldier or his unit. However, during the mission, the patient felt a sharp pain in the posterior aspect of the left shoulder. He was unsure as to the source of the pain, and had a medic evaluate his shoulder later that evening. The medic who examined him was not overly concerned due to the perceived benign exam findings and advised the soldier to return to duty. The patient continued with his mission until the following day, when he continued to be bothered by the discomfort. He examined the remainder of his arm and palpated a hard mass in his left triceps region, along with a small wound in his posterior upper left arm. This case illustrates the many dangers that our soldiers face while deployed, as well as reinforcing the evidence that celebratory gunfire can become a dangerous event causing significant morbidity and even mortality for those who are unfortunate enough to become a victim.

The Sonoma CRx device (Sonoma Orthopedic Products, Santa Rosa, California) is a recently introduced intramedullary device with a flexible shaft that becomes rigid once actuated to allow deployment within the sigmoidal contour of the clavicular shaft. Medial intramedullary cortical purchase is obtained by grippers and lateral purchase through a locking bicortical buttressing screw. This article describes 2 cases of early hardware failure using this device. In both cases, early postoperative radiographs demonstrate adequate initial fracture reduction and implant position. Both patients sustained repeat injuries, one under low physiologic load and the other after returning to mixed martial arts 4 months postoperatively. Implant failure was noted after reinjury in both cases. Complete healing and full return to function was documented for both patients at 2 years. Proper patient selection and counseling regarding the limitations of this intramedullary fixation device are important. Biomechanical comparison of this implant to plate fixation under physiologic loads of combined axial compression and torsion may shed light on differences in fixation stability.

The objective of this article is to review the surgical technique for quadriceps tendon graft harvest while highlighting an additional technical note that has not been previously emphasized. The quadriceps tendon typically inserts eccentrically on the superior pole of the patella. By shifting the soft-tissue harvest to a location just off the medial edge of the tendon, the adjoining patellar bone plug will be centered on the superior pole of the patella, reducing the risk of an iatrogenic patellar fracture.

The military offers eight Accreditation Council for Graduate Medical Education-accredited orthopaedic surgery programs with 33 total positions. The Army has 19 orthopedic surgery residency positions and averaged 1.47 applicants per position from 2007 to 2011. Applicants most commonly become eligible for military orthopaedic surgery residency through attendance of the Uniformed Services University of the Health Sciences or participation in the Health Professions Scholarship Program. The Military Operational Data System begins registration on July 1st of the preceding year and is used to match all applicants. The ranking and selection of applicants from medical school is based 50% upon objective criteria regarding the applicant's medical school performance and 50% on the applicant's potential for successful practice as an orthopaedic surgeon. Medical school performance data examined include medical school transcript, Dean's letter, and United States Medical Licensing Examination steps I and II/Comprehensive Osteopathic Medical Licensing Examination of the United Sates I and II scores. Determination of an applicant's potential is based upon letters of recommendation, personal interviews, and most importantly the applicant's performance on military orthopaedic surgery clinical clerkships. Applicants who have completed an internship are similarly scored with points awarded for internship and operational tour performance.

Multiple different surgical techniques have previously been described to address long head of the biceps tendinopathy. Subpectoral biceps tenodesis has proven to be an effective procedure to relieve pain and maintain function. We describe a surgical technique for subpectoral biceps tenodesis using a single double-loaded suture anchor implant. Advantages of this procedure include the ease of implant placement and the freedom this technique affords to perform the anchor placement without direct visualization of the docking site.

Autologous bone grafts harvested from the iliac crest are commonly used in reconstructive orthopaedic surgery. Autologous bone is used to help promote bone healing in fractures and to provide structural support for reconstructive surgery. The results of autologous bone grafting are more predictable than the use of xenografts, cadaveric allografts, or synthetic bone substitutes because autologous bone grafts provide osteoinductive and osteoconductive properties, are not immunogenic, and are usually well incorporated into the graft site. In a retrospective review of 414 consecutive cases of iliac crest bone graft procedures performed at Brooke Army Medical Center from 1983 to 1993, 41 (10%) minor and 24 (5.8%) major complications were identified. Minor complications included superficial infections, superficial seromas, and minor hematomas. Major complications included herniation of abdominal contents through massive bone graft donor sites, vascular injuries, deep infections at the donor site, neurologic injuries, deep hematoma formation requiring surgical intervention, and iliac wing fractures. Harvesting of iliac crest bone graft can be associated with significant morbidity. However, with adequate preoperative planning and proper surgical technique, the incidence of these complications can be reduced.

Muscular injuries are extremely common in athletes. Treatment of these injuries is based on a solid understanding of anatomy, physiology, and healing of skeletal muscle. Injuries discussed include contusions, hematomas, myositis ossificans, delayed onset soreness, strain, rhabdomyolysis, and lacerations. Diagnosis and treatment of these injuries is essential for the sports medicine physician.

Historically, complex extremity injuries, otherwise known as mangled extremities, have been difficult management problems. This is especially true in multiply-injured patients where many priorities exist and where amputation is considered a failure of limb salvage. Over the past decade, advances in the total management of complex extremity injuries, from the placement of life-saving and limb-saving tourniquets in the prehospital setting to the advancement of prosthetics and rehabilitation months to years later, have resulted in superb functional results regardless of whether limb salvage or amputation is undertaken.

Traumatic intrasubstance ruptures of the biceps brachii are rare and historically specific to military static line parachute jumps; however, these injuries have recently been reported in the civilian literature. Diagnosis is made by history, clinical weakness in supination and elbow flexion, extensive ecchymosis and edema, and a palpable defect. Ultrasound and magnetic resonance imaging are useful to confirm the diagnosis and injury severity. Nonoperative treatment involves splinting in acute flexion. Percutaneous hematoma aspiration has been described. Early surgical intervention with primary repair has been shown to be more successful than late reconstruction. Studies comparing operative and nonoperative treatment are lacking.

Facet dislocations in children are rare. This article presents the youngest case of a unilateral facet dislocation described in the pediatric population. A 9-year-old boy sustained a flexion/axial loading injury to his cervical spine while wrestling with his friends, causing a unilateral facet dislocation at C4/5. Prereduction magnetic resonance imaging (MRI) demonstrated the absence of a diskal herniation or cord impingement and an intact posterior ligamentous complex. Due to the patient’s young age, the decision was made to forgo a supervised awake closed reduction. Closed reduction was performed under general anesthesia with somatosensory-evoked potential and motor-evoked potential monitoring. Closed reduction was successfully achieved after Gardner-Wells tongs were applied and used to manually direct slow, steady in-line traction, along with slight flexion and posterior rotation of the dislocated side under direct fluoroscopy. The patient was immediately awakened from anesthesia and was found to have an intact sensory examination. He was immobilized in a cervical collar for 12 weeks. At 2-year follow-up, he remained asymptomatic without recurrence and had painless full range of motion of the cervical spine. Radiographs revealed a normally aligned cervical spine. Unilateral cervical facet dislocations and subluxations are the result of a distractionflexion force applied to the spine along with a rotational component. These are not uncommon injuries in the adult spine; however, in the young pediatric population, cervical facet dislocations are rare.

A retrospective review was performed of all osteochondroma excisions at our institution from 1994 to 2007. Postoperative functional assessment was completed with use of the Disabilities of the Arm, Shoulder and Hand (DASH) survey and a self-report questionnaire. Eight osteochondromas were excised at a mean patient age of 21.63 years. Presenting reports included pain, mass, pseudowinging, and snapping of the scapula. Physical examination identified pseudowinging, palpable mass, and pain with shoulder motion. The lesions arose from the ventral surface of the scapula in 5 patients, the dorsal surface in 2, and the inferior acromion in 1. The resected specimen averaged 10.8cm 3 . A reactive bursa was found and resected in 4 patients. At mean of 4.17 years postresection, no signs of recurrence were found in 7 patients (88%). The single patient with a recurrence had undergone 2 additional surgical procedures. Six patients (75%) reported no/mild pain with routine and strenuous activities. One patient reported moderate and 1 patient reported moderate/severe pain with routine and strenuous activities. Four patients reported post-resection function as excellent, 2 as good, 1 as average/good, and 1 as average/poor. Six patients (75%) reported feeling very satisfied with the results, 1 reported feeling satisfied, and 1 reported feeling unsatisfied. The average DASH score was 11.7 (range, 0.00–46.67). No winging or pseudowinging was identified in those available for examination, and no difference was identified in range of motion comparing the operative to the nonoperative upper extremity. Near normal functional outcomes can be expected following excision of scapular osteochondromas.

Monitoring of motor and somatosensory evoked potentials provides instantaneous intraoperative assessment of a patient's neurologic status. Monitoring of the sciatic nerve through motor and somatosensory evoked potentials can be used during open reduction and internal fixation of pelvic and acetabular fractures. A review of 12 pelvic and acetabular fractures treated with open reduction and internal fixation was conducted and assessed with a combination of intraoperative motor and somatosensory evoked potential monitoring. Results revealed intraoperative motor evoked potential monitoring was 1 00% sensitive and 1 00% specific in predicting postoperative sciatic nerve deficits, whereas somatosensory evoked potentials were not accurate in predicting postoperative sciatic nerve deficits. Combined monitoring of the sciatic nerve with motor and somatosensory evoked potentials is beneficial at predicting postoperative sciatic nerve deficits during open reduction and internal fixation of pelvic and acetabular fractures.
