A Modified "Shuttle" Method Technique for Arthroscopic Hip Capsular Reconstruction in Capsular Deficiency.

The hip capsule has been recognized as a vital structure in the stability and proper function of the hip. Preserving its integrity during arthroscopic surgery is one of the utmost important principles in hip preservation surgery. When capsular deficiency is present, capsular reconstruction may be indicated to restore stability and proper hip mechanics. In this technical note, we introduce a simple and reproducible shuttle method technique for hip capsular reconstruction using a dermal allograft.

Lateral Extra-articular Tenodesis: The Onlay Technique.

Tibial anterolateral rotary instability associated with anterior cruciate ligament (ACL) tears is a well-documented and difficult problem with a long history of solutions. The lateral extra-articular tenodesis (LET) has undergone multiple refinements in technique, largely focusing on the femoral site insertion using either an interference screw versus a staple for adequate fixation. In this article, we present an improved technique using a suture anchor as an alternative to a staple or an interference screw with secure fixation to insert the LET graft onto the femur. This technique diminishes the chance of ACL tunnel-LET drilling convergence, minimizes the footprint required for adequate graft fixation, and allows the surgeon to dial in the correct tension necessary for adequate augmentation of an ACL reconstruction.

Median Time to Return to Sports After Concussion Is Within 21 Days in 80% of Published Studies.

PURPOSE: To perform a systematic review of the literature and evaluate the return to play (RTP) time frame after a concussion diagnosis. Our secondary purpose was to analyze and compare different prognostic variables affecting concussions, time to return to school, time to symptom resolution of concussive symptoms, and time each patient spent in the RTP protocol. METHODS: A PubMed, Scopus, Medline, Embase, and Cochrane Library database literature review was performed in August 2022. The studies needed to report, in days, the length of time a patient/athlete was removed from play due to concussion management. The Risk of Bias in Non-Randomized Studies of Interventions tool was used for risk of bias for each study, and Methodological Index for Non-Randomized Studies criteria were used for quality assessment. RESULTS: There were 65 studies included in the systematic review and a total of 21,966 patients evaluated. The RTP time intervals ranged from 1 to 1,820 days, with 80.7% of the median RTP time frames for each study within 21 days. Preconcussion risk factors for prolonged RTP included female sex, younger age, presence of psychiatric disorders, and history of previous concussion. Postconcussion risk factors included severe symptom scores at initial clinic visit, loss of consciousness, nonelite athletes, and delayed removal from competition. The most common sports resulting in concussion were contact sports, most commonly football and soccer. Median time to return to school was 3 to 23 days. Median time to symptom resolution ranged from 2 to 11 days. Median time in RTP protocol was 1 to 6 days. CONCLUSIONS: Median time to return to sports after concussion is within 21 days in 80% of published studies. LEVEL OF EVIDENCE: IV, systematic review of Level I to IV studies.

Three-Dimensional Analysis Versus Two-Dimensional Slice-Based Analysis of CT for Measuring Femoral Torsion and Its Correlation to Passive Hip Range of Motion.

Introduction Femoral torsion is an important anatomical consideration of the hip that has major implications on the natural motion of the hip joint. Similarly, it affects pathologic conditions of the hip, including femoroacetabular impingement, dysplasia, and/or microinstability. Femoral torsion is typically measured on two-dimensional (2D) axial CT cuts by creating the angle between the femoral neck and the posterior aspect of the ipsilateral femoral condyles. Position of the leg during imaging may affect 2D measurements. Three-dimensional (3D) analysis of a hip CT with inclusion of femoral alignment may portray the anatomy of the hip more accurately as compared to a 2D slice-based analysis of a hip CT scan. It is thought that femoral torsion measured using this system could be a more accurate and reliable means of measurement. The primary purpose of this study is to assess the differences in measuring femoral torsion with 3D modeling and analysis compared to the standard 2D slice-based approach on a CT scan. Secondarily, we attempt to determine how the passive range of motion of the hip correlates with femoral torsion measured using the 3D model versus the 2D model. Methods In a prospective cohort study of 20 patients, femoral torsion was assessed using both 2D analysis and 3D analysis. The differences between these measurements on each of the imaging modalities were compared. Additionally, each patient had the passive range of motion of their hip measured with a goniometer. The amount of internal and external rotation was measured with the hip in a neutral position and with the hip flexed to 90°. Acetabular version, combined version, and alpha angle were added to multivariate regression analysis to evaluate their effect versus femoral torsion alone. Results Femoral antetorsion measured using the standard 2D slice-based approach on CT scan was 22.1° (SD: 11.1°), which was higher (p<0.001) than that using 3D analysis (8.25°; SD: 10.5°). There was a strong correlation between femoral torsion measurements using 3D analysis and 2D analysis (R=0.91). Based on 3D analysis, there was a moderate correlation between femoral torsion and passive hip external rotation measured with the hip flexed to 90° (R=0.65, p<0.002) and with the hip in a neutral position (R=0.58, p<0.007). Conclusion There was a significant difference between femoral torsion measurements using the 3D analysis, which showed approximately 14° of less antetorsion on average. Additionally, rotation of the hip and femoral torsion was correlated to higher levels of antetorsion associated with more internal rotation of the hip.

Elbow Dislocations in the National Football League: Epidemiology and Management.

Background Currently, it is not known how the combined osseous and ligamentous injury of a traumatic elbow dislocation in a National Football League (NFL) athlete affects management and return to play. In this study, we aimed to describe the epidemiology, management, and return to play for elbow dislocations in NFL athletes. Methodology This is a descriptive observational study. A retrospective review of all elbow dislocations between 2000 and 2014 (15 seasons) was performed using the NFL Injury Surveillance System (NFLISS). Results Over 15 NFL seasons, 82 elbow dislocations were recorded in the NFLISS. Among players who reported surgery (n = 5), players missed an average of 73.8 days of play. Among those who did not report surgery, players missed an average of 36.1 days. The overall incidence was 0.26 dislocation events per 10,000 athlete exposures. The majority of these injuries occurred during regular-season games, in defensive linebackers and linemen, during tackling contact with another player, and most commonly on a running play. Conclusions This study demonstrates that an elbow dislocation is not a career-ending or season-ending injury in an NFL cohort. Information regarding incidence, positions affected, whether surgical management is utilized, and return to play will help players who sustain and physicians who treat these injuries in elite football athletes understand the impact of their injuries.

Treatment of type III supracondylar humerus fractures: adherence and limitations of American Academy of Orthopedic Surgeons Appropriate Use Criteria App.

The American Academy of Orthopedic Surgeons (AAOS) published Appropriate Use Criteria (AUC) in 2014 to aid physicians in the management of pediatric supracondylar humerus fractures. AUC should be evaluated in real practice, and if necessary modified based on identified problems. This study compares AAOS AUC recommendations with actual treatment performed in a cohort of patients treated for type III supracondylar humerus fractures. Medical record review of patients treated for type III supracondylar humerus fractures at our hospital from 2009 to 2016. Criteria required by the AAOS AUC were collected and entered into the AAOS AUC web-based application to determine the 'appropriateness' and score of each treatment. These were compared with the actual treatment the patient received. Over the study period, 585 patients (mean age: 6.5 years, 51% male, 49% female) were treated for type III supracondylar humerus fractures. Of the 585 cases, 561 (95.9%) were classified as 'appropriate', 24 (4.1%) as 'maybe appropriate', and 0 (0%) as 'rarely appropriate'. Of the 'maybe appropriate' cases there was a significant decrease in the proportion that deviated from the AUC over time (P = 0.0076). The main reasons for deviation were that an open reduction was performed due to difficulty with closed reduction (75% of deviations) or the surgery was not performed emergently (25% of deviations). The vague definition of 'emergent' and not allowing for open reduction if needed are limitations of the AUC that should be clarified or improved by the AAOS.

Patterns of Pain in Adolescents with Slipped Capital Femoral Epiphysis.

OBJECTIVE: To prospectively characterize pain locations in slipped capital femoral epiphysis (SCFE) and evaluate pain locations as predictors of a delay in diagnosis. STUDY DESIGN: This was an institutional review board approved prospective study of 110 children who underwent surgery for SCFE at a tertiary children's hospital between 2009 and 2015. Standardized pain diagrams were completed by 107 children. Pain zones were designated via a composite diagram. Hips without hip pain were categorized as atypical; hips with hip pain were typical. RESULTS: In total, 122 hips were eligible for pain zone analysis. Seventy hips (57.4%) had hip pain. Atypical pain was present in 52 hips (42.6%), which included groin pain in 17 hips (13.9%), thigh/leg pain in 43 (35.2%), knee pain in 32 (26.2%), and posterolateral pain of the hip and leg in 13 (10.7%). A combination of pain zones was present in 48 hips (39.3%). Forty-nine percent of patients had more than 1 visit until diagnosis. The three most common pain locations for typical hips were hip, hip/thigh, and hip/knee pain (77.2% of typical hips). The 3 most common pain locations for atypical hips were isolated thigh, knee, and groin (65.4% of atypical hips). The least common pain presentations had a longer duration of symptoms (P = .04) and more healthcare visits before diagnosis (P = .04). CONCLUSIONS: A combination of pain locations is common in SCFE. Less frequent pain presentations may delay diagnosis. Delays in diagnosis continue despite education efforts.
