Spherical Periacetabular Osteotomy (SPO) is a novel procedure using an osteotomy line similar to that for Rotational Acetabular Osteotomy (RAO). The major difference between these procedures is that an anterior approach is used for SPO and an anterior and posterior approach for RAO. This study compared early bone union between these procedures. We enrolled 12 patients (12 hips) post-RAO and 15 patients (15 hips) post-SPO who consented to undergo computed tomography (CT) imaging about 5 weeks after surgery. Results showed no significant differences in lateral centre-edge angle or acetabular roof obliquity between these groups, both before and after surgery. Partial bone union was observed in 7 of 12 cases (58.3%) in the RAO group and 14 of 15 cases (93.3%) in the SPO group, with the SPO group showing a significantly higher incidence of bone union (

Patients with symptomatic hip dysplasia may undergo periacetabular osteotomy (PAO) and 10% of these patients have pain >6 months after the operation. An intra-articular lidocaine injection is used to determine if the pain comes from labral pathology in the hip joint or structures around the hip. To allow the patient a longer period of time to test the hip, we wanted to test if an intra-articular injection of Botox combined with local anaesthetic could reduce pain and allow the patient to test the hip. Eleven patients who received a PAO and suffered from persistent pain at least 6 months postoperative had an intra-articular joint injection with 100IE Botox, 3 ml NaCl water and 3 ml lidocaine. Hip pain on the day of injection and after 6 weeks was evaluated using the Visual Analog Scale score, International Hip Outcome Tool (iHOT-12), and Hip and Groin Outcome Score (HAGOS). Botox in the hip joint reduced the pain level and the iHOT-12 score, with a statistically significant improvement 6 weeks after injection. Hip joint injection of a controlled dosage of 100 IU diluted in 3 ml NaCl solution mixed with lidocaine had no side effects in this study with a limited group of patients. Botox has a promising pain-reducing effect on the hip joint in the majority of patients comparable with findings in knee and shoulder joints. Hip joint injection of a controlled dosage of 100 IU, 3 ml NaCl solution mixed with lidocaine had no side effects in this study with a limited group of patients.

Morphological hip abnormalities (MHAs) significantly influence lifelong prognosis of the hip, contributing to early-onset osteoarthritis and impaired functionality. Developmental dysplasia of the hip (DDH) and femoroacetabular impingement (FAI) represent key pathologies, resulting from insufficient or excessive femoral head coverage, respectively. These abnormalities alter hip biomechanics, leading to structural damage, pain, and accelerated joint degeneration. Advances in genetic research have illuminated the interplay between genetics and mechanical loading in shaping hip morphology. Genes associated with osteoarthritis, DDH, and FAI include

This study evaluates the effects of hip capsule repair and cam lesion excision on capsular healing by assessing biomechanical strength and histological integrity in an in vivo rabbit model.

Borderline hip dysplasia (BhD) may be associated with insufficient acetabular coverage. Thus, we investigated potential differences in acetabular anatomical measurements derived from computerised tomography (CT) that characterise BhD compared with healthy controls.

Patients undergoing revision hip arthroscopic surgery may elect to undergo the procedure with their index surgeon or, in many instances, will change surgeons. Factors and outcomes associated with switching surgeons are likely multifactorial and require further study.

The capacity of an unrepaired joint capsule to heal after primary hip arthroscopic surgery in patients with femoroacetabular impingement syndrome (FAIS) remains uncertain. The factors that may contribute to nonhealing of the joint capsule are yet to be elucidated.

Patients routinely undergo computed tomography (CT) before arthroscopy for femoroacetabular impingement as part of preoperative planning. These scans include the lower lumbar spine, entire pelvis, proximal femur, knees, and ankles, raising questions about the prevalence and clinical impact of incidental findings (IFs) from these images.

Femoroacetabular impingement (FAI) is a common cause of hip pain and dysfunction, particularly among athletes, including football players. The condition is characterized by abnormal contact between the femoral head-neck junction and the acetabulum, leading to cartilage damage and labral tears. Hip arthroscopy has emerged as a minimally invasive treatment option, offering faster recovery and improved outcomes compared to traditional surgery. This study aims to compare outcomes between football players and non-football athletes undergoing hip arthroscopy for FAI.

Femoroacetabular impingement (FAI) syndrome is a condition characterised by irregularities in the femur or acetabular rim, leading to hip pain, increased risk of osteoarthritis (OA), and potential need for total hip arthroplasty (THA). Non-surgical treatments are the first-line approach. However, arthroscopic surgery has become more prevalent due to its promising short- and medium-term outcomes. Recent meta-analyses suggest that hip arthroscopy may offer superior results compared to non-operative treatments, though follow-up periods in these studies have been limited to 12 months. This systematic review aims to evaluate the long-term effectiveness of arthroscopic management for FAI syndrome, hypothesising that it will significantly improve patient-reported outcomes (PROMs) over a follow-up period exceeding ten years.

The dynamic lumbopelvic interaction has gained increasing importance in hip-preserving surgery, even though the coexistence of lumbopelvic malalignment with pre-arthritic hip deformities has been poorly studied. This study aimed to examine (I) the frequency of static and functional lumbopelvic malalignment (II) and to compare the lumbopelvic alignment between symptomatic mild to severe hip dysplasia (HD) and impingement-driven acetabular retroversion (AR).

Total hip arthroplasty (THA) combined with a shortening osteotomy of the femur has proved to be an effective treatment for patients with developmental dysplasia of the hip (DDH). Advances in surgical technique and implant design have led to the introduction of customised THA, without the inconvenience of femoral shortening osteotomy, as an alternative option.The purpose of this retrospective study was to determine if customised THA without femoral shortening osteotomy improves the functional outcome and long-term survivorship in total hip arthroplasty for DDH.

To clarify the difference between the alpha angles measured by European method and by AIUM method.

Bone wax is a haemostatic agent, widely used to prevent bleeding from bone surfaces. Despite its effectiveness in haemostatic control, it can lead to foreign body granuloma and osteolysis. Therefore, the aim of this study was to assess the rate and progress of osteolysis after surgical bone wax application.

Hip arthroscopy (HA) for the surgical management of femoroacetabular impingement syndrome (FAIS) provides reliable improvements in pain and function; however, debate remains regarding the impact of HA on the progression of osteoarthritis (OA).

Traditional radiographic measurements for acetabular dysplasia and femoroacetabular impingement syndrome (FAIS) are typically done in static positions, overlooking dynamic behaviours. This study investigated the reproducibility of a new radiographic method that incorporates pelvic and femoral motion during running.

Altered hip loading and biomechanics in individuals with femoracetabular impingement syndrome (FAIS) may affect the joint's habitual mechanical environment, potentially increasing the risk of osteoarthritis . Examining differences in contributions of muscle and external loads (i.e., gravitational and intersegmental-inertial forces) to hip contact forces, compared with controls, may aid our understanding of FAIS pathomechanics and assist with the development of more effective treatments. Whole-body motion and electromyograms of 14 lower limb muscles were acquired from 41 participants with FAIS and 24 healthy controls whilst walking overground at self-selected speed. Contributions made by muscle and external (gravitational and intersegmental-inertial) forces to hip contact force during the stance phase of walking were estimated using an electromyogram-assisted neuromusculoskeletal model and compared between-groups using statistical parametric mapping. Throughout stance, muscle contributed ∼80% of hip contact force for both participants with FAIS and controls. Compared with controls, participants with FAIS generated ∼20% lower total muscle force (mean difference: -0.75 N·BW

Developmental dysplasia of the hip reduces hip stability due to insufficient femoral head coverage. Periacetabular osteotomy surgery aims to increase this coverage. Typically measured using radiographs, most coverage assessments are limited to static hip positions and cannot capture 3D anatomy. This study quantified how dynamic 3D femoral coverage changes during gait and squat after periacetabular osteotomy surgery and compared dynamic coverage to static measures.
