Background: The prevalence of labral tears in asymptomatic active adults has been reported, but the prevalence of labral tears and other incidental hip lesions in the asymptomatic active pediatric population remains unclear. The purpose of this study was to determine the prevalence of hip abnormalities detected on 3T MRI in an active pediatric population with no hip symptoms and to compare with hip abnormalities found in children and adolescents who underwent an MRI for a hip-related condition.
Methods: After IRB approval, pediatric patients self-reporting as athletes and presenting with isolated, acute-onset knee pain requiring knee MRI were prospectively recruited to undergo 3T MRI of their asymptomatic contralateral hip (ASx). A comparison group of pediatric subjects who underwent an MRI for hip pain was enrolled retrospectively (Sx). All MRI scans were anonymized and randomized. Fifty subjects were enrolled for each cohort. Two fellowship-trained musculoskeletal radiologists independently evaluated MRIs for abnormal hip lesions, including labral tears. Inter-reader reliability was evaluated using Cohen Kappa. χ2 or Fisher exact test was used to compare the prevalence of hip lesions between the 2 cohorts.
Results: The average patient age was 14.9 years for both cohorts (range 9 to 18 y) and 48% were male. In the ASx group, incidental labral tears were found in 18%, labral/paralabral cysts 6%, cartilage lesion 0%, subchondral cyst 0%, ligamentum teres tear 0%, femoral fibrocystic change 0%, cam lesion 30%, acetabular bone edema 0%, acetabular rim fracture 0%. The prevalence of labral tears (30%, P-value 0.16) and cam lesion (36%, P-value 0.52) in the Sx group was not significantly different from the ASx cohort. No significant correlation was found between the presence of femoral neck osseous bump and labral tear, labral cyst, or paralabral cyst in either cohort.
Conclusions: Labral tears were present on 3T MRIs of active pediatric patients with and without hip pain. Although MRI is essential to confirm the surgeon's suspicion and to detect unexpected pathology, clinical examination and history are crucial in pinpointing clinically relevant abnormal imaging findings.
Level Of Evidence: Level III.

Management of Labral Tears in the Hip: A Consensus Statement.
Orthop J Sports Med
January 2025
Pan Am Clinic and University of Manitoba, Winnipeg, Manitoba, Canada.
Background: Inconsistencies in the workup of labral tears in the hip have been shown to result in a delay in treatment and an increased cost to the medical system.
Purpose: To establish consensus statements among Canadian nonoperative/operative sports medicine physicians via a modified Delphi process on the diagnosis, nonoperative and operative management, and rehabilitation and return to play (RTP) of those with labral tears in the hip.
Study Design: A consensus statement.
Comparison of Glenoid Bone Loss After Unidirectional Versus Combined Shoulder Instability in a Military Population.
Orthop J Sports Med
January 2025
Department of Orthopaedic Surgery, Carthage Area Hospital, Carthage, New York, USA.
Background: While glenoid bone loss (GBL) after anterior shoulder instability correlates with poor functional outcomes, the specific effects of GBL in posterior and combined-type shoulder instability remain poorly characterized, especially in a high-risk military population.
Purpose/hypothesis: The purpose of this study was to compare GBL between unidirectional anterior or posterior instability versus combined-type instability in active-duty servicemembers. It was hypothesized that total GBL and GBL in the direction of instability would be greater in those with combined-type instability compared with unidirectional instability.

Background: Sex has been associated with different pathologic characteristics in painful hips undergoing hip arthroscopic surgery.
Purpose: To compare minimum 10-year patient-reported outcomes (PROs) and survivorship in patients who underwent primary hip arthroscopic surgery for femoroacetabular impingement syndrome and labral tears according to sex.

Hip-Spine Relationship in Femoroacetabular Impingement: Does Hip Arthroscopy Affect Pelvic Mobility?
Clin Orthop Relat Res
December 2024
Naval Medical Center San Diego, San Diego, CA, USA.
Background: Femoroacetabular impingement (FAI) is a well-recognized cause of hip pain in adults. The hip-spine relationship between the femur, pelvis, and lumbosacral spine has garnered recent attention in hip arthroplasty. However, the hip-spine relationship has not been well described in patients with FAI.
