RESUMEN
Children with cerebral palsy (CP) and those with avascular necosis (AVN) after treatment of developmental hip dysplasia (DDH) are at risk of developing coxa valga. Proximal femur guided growth is a minimally invasive option to correct this deformity. A systematic review of articles that described treatment of coxa valga with proximal femur guided growth (PFGG) and reporting on primary radiographic outcomes, demographic variables, surgical variables and complications. One hundred and seventy-nine hips underwent PFGG (117 with CP and 62 with lateral overgrowth). Average age at surgery was 8.1 years; average follow-up was 52.5 months. Migration percentage improved from 11.2% (p < 0.0001). Neck-shaft angle improved by 11.9° (p < 0.0001). The most common complication was screw growth out of the physis (30% of cases). PFGG can correct coxa valga, improve radiographic parameters, and in children with CP prevent further subluxation. This technique modulates proximal femur growth, induces changes to the acetabulum and can correct valgus deformity. Evidence Level III. (Journal of Surgical Orthopaedic Advances 32(4):049-052, 2024).

Treatment of medial epicondyle fractures is controversial in pediatric orthopaedics with a recent trend towards operative fixation in overhead athletes. We performed a systematic review to compare outcomes in operative and non-operatively overhead athletes. A systematic review of the literature was performed. Articles investing pediatric athletes with medial epicondyle fractures treated operatively and non-operatively that reported functional and radiographic outcomes were compiled. We identified 6 studies with a total of 99 patients (52 treated operatively and 47 treated non-operatively). We found a significantly higher union rate with operative treatment (100%) compared to non-operative treatment (76%, p = 0.0025), with equivalent return to sport time and rate. Non-operative treatment had a lower complication and repeat surgery rates (p = 0.009). This study demonstrates lower complication rates and equivalent functional outcomes between operative and non-operatively treated medial epicondyle fractures in athletes. Non-operative treatment is a valid option in these patients. (Journal of Surgical Orthopaedic Advances 32(1):009-013, 2023).

PURPOSE: To report short-term outcomes following biceps tenodesis combined with arthroscopic posterior labral repair of type VIII SLAP lesions in active-duty military patients. METHODS: All consecutive patients from January 2012 through December 2018 who underwent biceps tenodesis combined with arthroscopic posterior labral repair of type VIII SLAP tears performed by the senior surgeon with complete outcome scores and minimum 2.5 years follow-up were identified. Exclusion criteria included concomitant glenoid microfracture, rotator cuff repair, or other capsulolabral repair. Outcome measures were completed by patients within 7 days before surgery and at latest follow-up. Biceps tenodesis performed was a mini-open, through a subpectoral approach, using a double-loaded 2.9mm suture-anchor. RESULTS: Thirty-two patients met the inclusion criteria for the study. All patients were active-duty military at time of surgery. Average follow-up was 73.53 ± 22.37 months. Thirty-one patients achieved the minimal clinically important difference, 30 of 32 reached the substantial clinical benefit, and 31 of 32 met the patient acceptable symptomatic state, as defined for the American Shoulder and Elbow Surgeons Shoulder Score. Similarly, 30 of 32 patients reached the minimal clinically important difference, 29 of 32 achieved the substantial clinical benefit, and 32 of 32 met the patient acceptable symptomatic state for the Single Assessment Numeric Evaluation. There were no significant changes in forward flexion, external rotation, or internal rotation between pre- and postoperative measurements. Three patients reported postoperative complications and 1 patient progressed to further surgery. Thirty (93.75%) patients remained on active-duty military service and were able to return to preinjury levels of activity. CONCLUSIONS: Active-duty military patients with type VIII SLAP tears had statistically and clinically significant increases in outcome scores, marked improvement in pain, and high rates of return to unrestricted active-duty following mini-open subpectoral biceps tenodesis combined with posterior labral repair. LEVEL OF EVIDENCE: IV, retrospective case series.

Pectoralis major tendon injuries are an uncommon injury. They can be treated with primary repair, however, when the tendon becomes retracted it necessitates tendon reconstruction. We performed a systematic review to evaluate patient characteristics, surgical techniques, and outcomes associated with pectoralis major reconstruction. A review was performed for studies published between 1990 and 2019. Peer-reviewed studies with a minimum 1-year follow-up were included. Return to activity, range of motion, complications, and functional outcome scores were primary outcomes. Fourteen primary studies with 88 total patients met inclusion criteria. All patients were male with the average age of 34.6 years-old. Hamstring autograft represented the most frequently used graft type (35). Functional outcomes demonstrated good to excellent results in the majority of patients. Pectoralis major tendon reconstruction is a viable option for tears not amenable to primary repair. We found good to excellent outcomes, and 94.2% return to sport for patients undergoing reconstruction. (Journal of Surgical Orthopaedic Advances 31(2):123-126, 2022).

PURPOSE: Combat-sustained peripheral nerve injuries (CSPNIs) are often the result of high-energy blast mechanisms and are increasing in frequency and severity among US forces engaged in contemporary warfare. The purpose of this study was to describe CSPNIs and report outcomes after evaluation in a military multidisciplinary peripheral nerve clinic. We hypothesized that a shorter time to evaluation by a multidisciplinary peripheral nerve team would improve outcomes. METHODS: The Peripheral Nerve Consortium (PNC) maintains an electronic database of all active duty service members who sustained a peripheral nerve injury (PNI) and were treated by the PNC between 2004 and 2009. This database was queried for service member demographic information, injury characteristics, wounding patterns, CSPNI description, surgical procedures, and Medical Research Council final motor and sensory outcome. RESULTS: Among the 104 service members treated by the PNC in the 6-year period reviewed, there were 138 PNIs. Average age was 27 years, time to initial evaluation by the PNC was 4 (±7) months, and average follow-up was 18 (±18) months. Associated injuries included fractures (31.1%), multiple PNIs (76.8%), vascular injury (30.4%), and traumatic brain injury (34.1%). There was no association between Sunderland classification and time to evaluation, mechanism of injury, or nerve injured. However, Sunderland classification was correlated with final motor and final sensory scores. Service members with better final sensory score (S1 or S2) had shorter time to initial evaluation than did patients with a final sensory score of S0 (<0.05). This did not hold true for final motor score. CONCLUSIONS: Service members with more severe initial injuries had worse final outcomes. Although timely referral does not occur for most CSPNIs, a shorter time to presentation also led to improved sensory recovery. Complex combat-sustained PNIs may be best understood and treated within a multidisciplinary team. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Military orthopaedic surgeons are faced with hardship and decreased morale. Surgeons have frequent deployments and practice inefficiencies resulting in poor retention rates. The purpose of this analysis is to report demographics and factors effecting military retention. A survey was sent to all members of the Society of Military Orthopedic Surgeons. The survey obtained demographic information, as well as factors affecting retention and termination of service. Data was compared between subset groups within the total respondent population. Of active-duty personnel, 38.5% plan on staying in the military until retirement. Most surgeons entered into the military due to a desire to serve their country, while most people leave service due to higher pay as a civilian. A minority of military orthopaedic surgeons achieve military retirement; however, increased pay, increased control over practice, and decreased frequency of deployments are factors that could improve retention rates.

HYPOTHESIS: The objective of this study was to compare the subjective and objective midterm functional clinical outcomes of subcutaneous anterior transposition (SAT) vs. in situ decompression (SD) of the ulnar nerve for the treatment of cubital tunnel syndrome. METHODS: The US Military Health System was queried to identify all cases of ulnar neuroplasty (Current Procedural Terminology code 64718) between 2006 and 2010. Patient charts were reviewed to identify cases of isolated SAT and SD, and demographic and surgical variables were collected. The primary outcome variable was the Disabilities of the Arm, Shoulder and Hand score. The inclusion criteria were isolated primary SAT or SD and adult active-duty service members with a minimum 6-year telephone follow-up. Terminal follow-up was determined by a telephone interview. The exclusion criteria were revision procedures, trauma, cases that included other procedures (eg, medial epicondylectomy, submuscular transposition, arthroscopy, or fracture fixation), non-active-duty service members, patients without a minimum 6-year telephone follow-up, and patients who had incomplete medical records or could not be reached to complete the survey. RESULTS: A total of 65 SD and 67 SAT patients met the inclusion and exclusion criteria, with a 72% telephone interview response rate. The average age was 32.3 years for all patients, with an average follow-up period of 6.5 years for SD patients and 6.3 years for SAT patients. SD patients had a lower mean Disabilities of the Arm, Shoulder and Hand score than SAT patients. No difference in reoperation rate was found. CONCLUSION: The active-duty cohort reported positive outcomes and a low reoperation rate at 6-year follow-up both after SAT and after SD. SD patients had mildly superior clinical outcomes compared with SAT patients.

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.

Dystrophin and utrophin are highly similar proteins that both link cortical actin filaments with a complex of sarcolemmal glycoproteins, yet localize to different subcellular domains within normal muscle cells. In mdx mice and Duchenne muscular dystrophy patients, dystrophin is lacking and utrophin is consequently up-regulated and redistributed to locations normally occupied by dystrophin. Transgenic overexpression of utrophin has been shown to significantly improve aspects of the disease phenotype in the mdx mouse; therefore, utrophin up-regulation is under intense investigation as a potential therapy for Duchenne muscular dystrophy. Here we biochemically compared the previously documented microtubule binding activity of dystrophin with utrophin and analyzed several transgenic mouse models to identify phenotypes of the mdx mouse that remain despite transgenic utrophin overexpression. Our in vitro analyses revealed that dystrophin binds microtubules with high affinity and pauses microtubule polymerization, whereas utrophin has no activity in either assay. We also found that transgenic utrophin overexpression does not correct subsarcolemmal microtubule lattice disorganization, loss of torque production after in vivo eccentric contractions, or physical inactivity after mild exercise. Finally, our data suggest that exercise-induced inactivity correlates with loss of sarcolemmal neuronal NOS localization in mdx muscle, whereas loss of in vivo torque production after eccentric contraction-induced injury is associated with microtubule lattice disorganization.

Elbow fractures comprise 15% of all fractures in children. Our study identifies risk factors and consumer products that contribute to pediatric elbow fractures. The National Electronic Injury Surveillance System was used to collect demographic and consumer product information between 2010 and 2019 for patients younger than 17 years who presented to the emergency department with elbow fractures. Of the 458,433 elbow fractures, the average age of the patients was 7.4 ± 4.1 years and 55.6% were male children. The most common consumer product was sports and recreation equipment, followed by home furnishings. Male patients (P < .0001) and patients 8 years and older (79.2% vs 51.1%, P < .0001) experienced significantly greater rates of injury with sports and recreation equipment. This study evaluates the products associated with pediatric elbow fractures and highlights the importance of safe sports and recreation equipment use and the role of parental counseling in preventing falls from furniture.

BACKGROUND: Upper extremity injuries account for 36.5% of presentations to the emergency department in the United States. This study seeks to determine current rates of upper extremity injuries that present to the emergency department and the injury characteristics of patients requiring admission. METHODS: National Electronic Injury Surveillance System was queried for a 10-year period for upper extremity injuries. Further analysis was done to evaluate specific patient demographics, injury characteristics, and mechanisms of injury of those patients who were admitted to the hospital. RESULTS: Between 2012 and 2021, 39 160 365 persons are estimated to have presented to 100 United States emergency departments for managing upper extremity injuries, accounting for 28.8% of total presentations. A total of 12 662 041 upper extremity patients were pediatric (32.3%). Admissions occurred in 4.6% of presentations. The most common presenting diagnosis was laceration (24.9%), while the most common admission diagnosis was fracture (49.7%). The majority had injuries involving their forearms (19.9%). The most common injury-associated consumer product group was stairs, ramps, landings, and floors at 28.5%. Of the 445 644 patients, those estimated to have been injured by stairs, ramps, landings, and floors adults were 429 435 or 96.4%. The most common injury-associated product in pediatric populations was playground equipment (23.6%), of which 53.7% was from monkey bars and other climbing apparatuses. CONCLUSION: This study demonstrates an overall increase in admissions for upper extremity injuries in the setting of similar rates of overall upper extremity injuries with fractures and forearm being the most common diagnosis and body part involved, respectively. LEVEL OF EVIDENCE: IV; Database.
RESUMEN
BACKGROUND: Glenohumeral dislocation is a common injury that may predispose patients to chronic pain and instability. However, there is a paucity of current data available regarding the epidemiological trends of this injury. AIM: To provide an updated, comparative assessment of the epidemiology of shoulder dislocations presenting to emergency departments in the United States. We also sought to analyze patient demographic risk factors and consumer products associated with dislocation events. METHODS: Data were obtained from the national electronic injury surveillance system database for glenohumeral dislocations between 2012 and 2021. Incidence, age, sex, and injury characteristics were analyzed using weighted population statistics as well as incidence rates and 95% confidence intervals (CI). RESULTS: In total, an estimated 773039 shoulder dislocations (CI: 640598-905481) presented to emergency rooms across the United States during the study period. The annual incidence rate was 23.96 per 100000 persons and the average patient age at the time of injury was 37.1 years. Significantly more male patients sustained dislocations than female patients (537189, 69.5%, vs 235834, 30.5%, P < 0.001). With regard to associated consumer products, sports and recreation equipment were involved in the highest proportion of incidents (44.31%), followed by home structures and construction materials (21.22%), and home furnishings, fixtures, and accessories (21.21%). Regarding product sub-groups, stairs, ramps, landings, floors was cited in the greatest number of cases (131745). CONCLUSION: The national annual incidence rate of glenohumeral dislocations throughout the study period was approximately 23.92 per 100000 persons. Male adolescents sustained the highest proportion of dislocations, with a peak incidence in age group 15-20 years, predominantly secondary to participation in sporting and recreational activities. Conversely, women experienced a relatively consistent incidence of dislocation throughout their lifespan. After age 63, the incidence rate of dislocations in females was found to surpass that observed in males.
RESUMEN
INTRODUCTION: The purpose of this study was to determine the most common allegations for malpractice litigation brought against orthopaedic surgeons for oncologic matters and the resulting verdicts. METHODS: The Westlaw Legal research database was queried for malpractice cases filed against orthopaedic surgeons for oncologic matters in the United States after 1980. Plaintiff demographics, state of filing, allegations, and outcomes of lawsuits were recorded and reported accordingly. RESULTS: A total of 36 cases met the inclusion and exclusion criteria and were subsequently included in the final analysis. The overall rate of cases filed remained consistent through the past four decades and was primarily related to a primary sarcoma diagnosis in adult women. The primary reason for litigation was failure to diagnose a primary malignant sarcoma (42%) followed by failure to diagnose unrelated carcinoma (19%). The most common states of filing were primarily located in the Northeast (47%), where a plaintiff verdict was also more commonly encountered as compared with other regions. Damages awarded averaged $1,672,500 with a range of $134, 231 to $6,250,000 and a median of $918,750. CONCLUSION: Failure to diagnose primary malignant sarcoma and unrelated carcinoma was the most common reason for oncologic litigation brought against orthopaedic surgeons. Although most of the cases ruled in favor of the defendant surgeon, it is important for orthopaedic surgeons to be aware of the potential errors that not only prevent litigation but also improve patient care.

The purpose of this study is to ascertain which factors are associated with successful replantation in the upper extremity. Secondarily, the purpose was to determine patient factors that differentiate those patients who undergo initial replantation versus initial amputation. Methods: Data gathered for this retrospective study were obtained from a custom subset of the 2015-2020 IBM Truven MarketScan Commercial and IBM Truven MarketScan Medicare Supplemental databases. Data were sorted using Current Procedural Terminology codes and International Classification of Disease, Ninth and Tenth Revision, diagnosis codes. Results: Increasing age was significantly associated with undergoing initial amputation compared with replantation (P < 0.001; 95% CI, 47.146-50.654). Among comorbid conditions, patients with diabetes mellitus type II (2.4% versus 24.3%; P < 0.001), hypertension (11.9% versus 28.0%; P = 0.03), end-stage renal disease (0% versus 10.5%; P = 0.03), and hypertensive chronic kidney disease (0% versus 8.7%; P = 0.04) more commonly underwent an initial amputation procedure. When evaluating the need for secondary procedure after replantation, there was no statistical significance between groups when comparing age, gender, insurance type, general comorbidities, connective tissue disorders, mental health disorders, or geographic location. Conclusions: In conclusion, this study demonstrates that age and the presence of comorbidities are important factors in the differentiation of which patients undergo initial reimplantation versus initial amputation. Additionally, no specific factors were identified that were associated with secondary procedures after replantation.
RESUMEN
BACKGROUND: Traumatic finger amputations are a common and well-known hand injury, yet there are few studies addressing long-term epidemiologic data and associated mechanisms of injury. This paper aims to use a large national database to identify the relationship of patient demographics and mechanism of injury in finger amputations. METHODS: The National Electronic Injury Surveillance System (NEISS) was queried for finger amputations in the United States from 2010 to 2019. Patient demographic information was collected and analyzed by gender, race, age, and further statistical analysis was performed to determine correlations with consumer products. RESULTS: Finger amputations accounted for an estimated 234,304 emergency department visits from 2010 to 2019. Most of the patients were male (79%) and identified as white (46.2%). The most commonly implicated products overall were power saws and related power tools, followed by doors and then lawn mowers. A bimodal age incidence was observed with the highest incidence rates occurring in children ages 0 to 4, followed by a second peak incidence rate in the adults ages 65 to 74. The most common mechanisms of injury were found to differ in patients less than 19 and those 20 and over. CONCLUSION: Traumatic finger amputations have a bimodal incidence with changing epidemiology and mechanism of injury with age. The first peak occurs from ages 0 to 4, involves predominantly doors, and has a male to female ratio of 1.30. The second peak occurs from ages 65 to 74, involves mostly power saws, and has a male to female ratio of 6.68. LEVEL OF EVIDENCE: Prognostic, Level IV.
RESUMEN
BACKGROUND: Arthroscopic rotator cuff repair is an effective procedure through which to decrease pain and increase strength, with favorable long-term outcomes demonstrated in older patient populations with full-thickness rotator cuff tears. The long-term outcomes after this procedure in younger, higher-demand patients, however, is not as clearly defined. PURPOSE: To report on the long-term outcomes after arthroscopic rotator cuff repair of traumatic full-thickness rotator cuff tears in active duty military patients under the age of 40 years at the time of surgery. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Preoperative, midterm, and final evaluations were collected, including scores on the visual analog scale for pain, Single Assessment Numeric Evaluation, and American Shoulder and Elbow Surgeons shoulder form. A total of 42 patients were screened for inclusion: 3 underwent additional surgical procedures on the operative shoulder and 2 were lost to follow-up, leaving 37 patients with mean follow-up of 104.51 months available for analysis. A subgroup analysis was performed comparing outcomes between patients with Southern California Orthopaedic Institute grade 1 or 2 tears and those with grade 3 or 4 tears. RESULTS: At final follow-up, pain per the visual analog scale decreased to 1.16 from 8.03 (P < .0001); the Single Assessment Numeric Evaluation score increased to 87.32 from 48.24 (P < .0001); and the American Shoulder and Elbow Surgeons score increased to 88.68 from 41.00 (P < .0001). There was no statistically significant difference in outcome scores or range of motion between midterm and final follow-up. Improvement in outcome scores and range of motion at final follow-up did not vary between patients with small and large tears. Of 42 patients, 37 (88.1%) were able to return to full unrestricted active duty and sporting activity, while 5 (11.9%) were medically separated from the military. CONCLUSION: Active duty military patients under the age of 40 years with traumatic full-thickness rotator cuff tears had statistically and clinically significant increases in outcome scores and decreases in pain after arthroscopic rotator cuff repair at long-term follow-up.

Introduction: Lateral condyle fractures are the second most common pediatric elbow fracture. There exist multiple options for internal fixation including buried K-wires, unburied K-wires, and screw fixation. Our study aims to review the current literature and determine if fixation strategy affects outcomes to include fracture union, postoperative range of motion, and need subsequent surgery. Methods: A systematic review of Pubmed, MEDLINE, and EMBASE databases was performed. Included articles involve pediatric patients with displaced lateral condyle fractures treated with internal fixation that reported outcomes to include union rates and complications. Results: Thirteen studies met inclusion criteria for a total of 1299 patients (472 buried K-wires, 717 unburied K-wires, and 110 screws). The patients' average age was 5.8 ± 0.6 years, male (64%), and had 16.3 months of follow-up. No differences in union and infection rates were found. Unburied K-wires had the shortest time to union and the greatest elbow range of motion postoperatively. Conclusions: Our systematic review demonstrates similar outcomes with union and infection rates between all fixation techniques. Unburied K-wires demonstrated a shorter time to union and the greatest postoperative range of motion. Additionally, unburied K-wires may be removed in clinic, decreasing the cost on the healthcare system. Evidence: Level 3.
RESUMEN
Development of malignancy is a multifactorial process, and there are multitude of conditions of bone that may predispose patients to malignancy. Etiologies of malignancy include benign osseous conditions, genetic predisposition, and extrinsic conditions. New-onset pain or growth in a previously stable lesion is that should concern for malignant change and should prompt a diagnostic workup for malignancy.

¼: Enchondromas are benign cartilaginous lesions that rarely require surgical intervention. ¼: Atypical cartilaginous tumors (ACTs), also referred to as grade-1 chondrosarcomas, may be managed without any intervention or with extended intralesional curettage and bone-void filling. ¼: High-grade chondrosarcomas, or grade-2 and 3 chondrosarcomas, should be managed aggressively with wide resection. ¼: Chemotherapy and radiation do not currently play a role in the treatment of chondrosarcomas. ¼: Differentiating an enchondroma from an ACT and an ACT from a high-grade chondrosarcoma can be difficult and requires clinical experience, radiographic and advanced imaging, and possibly a biopsy. Ultimately, a multidisciplinary team that includes a musculoskeletal oncologist, a radiologist, and a pathologist is needed to make the most appropriate diagnosis and treatment plan for each patient.

Since the civil war, combat sustained peripheral nerve injuries (CSPNI) have been documented during wartime. Warfare has evolved and current combat involves a greater severity of blast injuries secondary to increased use of improvised explosive devices. The purpose of this study was to describe CSPNI and report outcomes after evaluation and treatment. We hypothesize that a shorter time to evaluation will improve outcomes. METHODS: A database including all active duty service members who sustained a CSPNI and were treated by the PNC between 2004 and 2009 was used. Service member demographic information, injury mechanism, CSPNI description, and Medical Research Council (MRC) final motor and sensory outcomes were queried from this database. RESULTS: One hundred and four military service members sustained 144 PNIs. The average age was 26.7 years, and nearly all were men (98.1%). There was no correlation between Sunderland classification and age, specific PNI, injury type, or time to evaluation. Higher Sunderland classifications were found to be correlated with worse final motor (r = 0.51, P < 0.001) and final sensory (r = 0.41, P < 0.001) scores. Final motor and sensory scores were not associated with specific nerve injury, mechanism of injury, initial EMG, or surgical procedure. Shorter time to initial assessment was associated with improved final motor and sensory scores, but was not found to be statistically significant. CONCLUSIONS: As the complexity of CSPNIs progress as combat weaponry evolves, a firm understanding of treatment factors is important. Our study demonstrates in recent conflict that military service members' initial injury severity is a key factor in expected outcome.
