Background and Objectives: The number of hip arthroscopy procedures is on the rise worldwide, and awareness regarding proper management of the hip capsule has increased. No capsulotomy shape is agreed upon as a standard approach, with literature supporting both isolated interportal and T-shaped capsulotomies. The aim of this retrospective cohort study is to report the clinical results of a standardized extended interportal capsulotomy (EIPC) during hip arthroscopy. Materials and Methods: Patients operated on between 2017 and 2020 with a hip arthroscopy were eligible. The inclusion criteria were ages 18–60 years, failed non-operative treatment, and at least a 2-year follow-up. Exclusion criteria were bilateral femoroacetabular impingement syndrome (FAS) cases or labral lesions, ipsilateral knee injury, history of ipsilateral hip surgery, and significant spine lesions. Data regarding demographic characteristics such as age, gender, operation date, BMI, but also Beighton score, presence of postoperative pudendal nerve damage, and revision for any reason were gathered from patients’ records. All patients were evaluated preoperatively with a visual analog scale (VAS), the Hip Disability and Osteoarthritis Outcome Score (HOOS), and the modified Harris Hip Score (mHHS). Results: Of the 97 patients operated on with a hip arthroscopy between the defined dates, only 90 patients were included. The mean age was 37.9 ± 9.8, and 58.9% of patients were male. The most frequent surgical indication was an isolated FAS lesion (73.3%), followed by FAS associated with a labral tear (12.2%), an isolated labrum tear (10.0%), synovitis (3.3%), and a loose body (1.1%). The mean follow-up for the study cohort was 39.3 months. The majority of the patients had uneventful surgeries (76.7%), while there were three cases of sciatic nerve neuropraxia and 12 cases of pudendal nerve neuropraxia. Two patients underwent revision surgery during the study period. Comparison between preoperative and postoperative clinical scores showed a significant improvement with a final mHHS mean value of 67.7 ± 18.2, an HOOS value of 74.1 ± 13.2, and a low VAS score of 1.3 ± 1.2. Conclusions: A hip arthroscopy procedure with a standardized and unrepaired, extended interportal capsulotomy is a safe procedure with satisfactory mid-term results and high overall patient satisfaction. At a minimum of 2 years and a mean of 39.2 months, patients showed improved clinical scores and a low revision rate.

OBJECTIVES: To assess the correlation between the amount of proximal screw lateralization and clinical symptoms in patients treated with a cephalomedullary nail (CMN) after a pertrochanteric fracture. METHODS: Design: Retrospective study. Setting: Level 1 trauma center. Patient Selection Criteria: Patients operated for a pertrochanteric fracture (OTA/AO A1, A2, A3) between 2019 and 2022 and treated with a CMN were included. Outcome Measures and Comparisons: Three measurements were evaluated: D1 distance between the most laterally prominent point of the lag screw and the line tangent to the greater trochanter, D2 distance between the lateral femoral cortex and the most laterally prominent point of the lag screw, and D3 distance between the point where the lag screw emerges at the lateral edge of the femur shaft and the skin's surface. Clinical scores and information regarding lateral thigh pain were obtained, and a correlation analysis was performed. RESULTS: Mean age of the study cohort (n = 134) was 77.9 ± 12.3 years. Patients with categorical protrusion (considered present in cases where the distance between the lateral tip of the lag screw and the lateral border of the greater trochanter was ≥0.2 mm) had significantly higher rates of lateral thigh pain (P = 0.007) and discomfort while lying on the side (P = 0.032) compared with those without protrusion. Correlation analyses showed a positive correlation between measurements D1 and D2 and lateral thigh pain (r = 0.324 and r = 0.334, respectively, P < 0.001) and a negative correlation between D3 and lateral thigh pain (r = −0.286, P = 0.001). Regression analysis showed that higher D1 and D2 distances and shorter D3 distances are risk factors for lateral thigh pain (P = 0.001, 0.001, and 0.002, respectively). CONCLUSIONS: Increasing lateral protrusion of the lag screw leads to significantly greater clinical complaints and lateral hip pain in patients treated with a CMN. Patients with lower distance between the lateral femoral wall and the skin are at higher risk of lateral pain. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Background: Physical examination findings such as limited hip abduction (LHA), asymmetric skin creases (ASC), and a popping sensation in the hip facilitate the diagnosis of developmental dysplasia of the hip (DDH). Screening with a simple physical examination during the first weeks of infancy is important for early detection of the condition, and a wide range of medical professionals, including general practitioners, obstetricians, pediatricians, and orthopedic surgeons etc. are involved in this process. The aim of this study was to determine the correlation between easily recognizable physical examination findings such as LHA, thigh/groin ACSs, and Ortolani and Barlow tests with ultrasound findings for the diagnosis of DDH. Methods: This study included 968 patients undergoing routine hip ultrasonography between December 2012 and January 2015. All patients were examined by an experienced orthopedic surgeon who was not the physician who performed the ultrasound examination to exclude bias between physical examination findings and ultrasound findings. Asymmetric skin folds (thigh and groin), limited abduction, Barlow and Ortolani tests were recorded. The relationship between the physical examination findings, ultrasound findings, and developmental dysplasia was investigated. Results: Of the 968 patients, 523 were female (54%) and 445 were male. On ultrasonography examination, 117 patients were found to have DDH. The sensitivity, specificity and negative predictive values of patients who were found to have both LHA and thigh/groin ASCs in all three physical examinations were high (83.8%, 70.2%, and 96.9%, respectively) while positive predictive values were found to be low (27.8%). Conclusion: Asymmetric skin creases on the thigh and groin and limited hip abduction, when evaluated together, have high sensitivity and specificity with additional high negative predictive values and could help during the initial screening process of DDH.

Introduction Lateral pain around the greater trochanter (LTP) is a common complication after total hip arthroplasty (THA) that can significantly reduce quality of life. The aim of this study was to analyze the relationship between lateral trochanteric bursa repair, subcutaneous fat thickness, and trochanteric pain during the THA procedure. Materials and methods A total of 98 patients who underwent THA for hip arthrosis between 2021 and 2022 were evaluated retrospectively. For all evaluated patients, subcutaneous thickness was measured between the fascia and the skin at the incision site. Bursa repair was performed in 47 patients, while bursa excision was done in 51 patients. The data obtained included demographic information, functional scores, comorbidities, bursa repair and skin thickness values, radiographic evaluations, and other specific markers. These were compared between patients diagnosed with LTP following THA and the controls. Results No difference was observed between the study groups in terms of subcutaneous fat thickness, bursa repair, and other demographic or radiographic evaluations. As expected, there were statistically significant differences between the groups in terms of the visual analog scale (VAS) score (p=0.030) and the Harris hip score (HHS) (p=0.045). When comparing the groups with and without LTP, the VAS score was higher in the group with LTP, while the HHS was found to be lower. Conclusion Trochanteric pain is not associated with bursa repair or subcutaneous thickness. LTP cannot be predicted based on comorbidities such as smoking, BMI, or radiographic measurements.
