Summary: The modified Ilizarov hip reconstruction surgery offers a minimally invasive, safe, and effective alternative for hip replacement surgery with satisfactory clinical outcomes. It significantly reduces surgery time and discomfort to patients, while avoiding disruption of blood supply at the osteotomy sites.

Summary: There is no clear consensus on whether placing the acetabular cup in the high hip center or the anatomic hip center provides better outcomes or long-term survival in patients undergoing THA for developmental dysplasia of the hip. Both cup positions have their own advantages and disadvantages, and surgeons should consider factors such as surgical complexity, complications, and hip biomechanics when making a choice. Researchers should address limitations in future studies, such as confounding factors, inconsistent definitions, variations in disease severity, small sample sizes, and follow-up periods.

Summary: Total hip arthroplasty after prior pelvic osteotomy is technically demanding, leading to longer operative times, greater blood loss, and variation in implant placement. Although functional outcomes are similar, total hip arthroplasty after a prior pelvic osteotomy is more likely to require reoperation.

Summary: Insufficient coverage of the hip joint can lead to instability and pain. This study investigates the correlation between four parameters on pelvic radiographs and the anterior center edge angle on false profile radiographs. The results show inconsistent correlation between these parameters on pelvic radiographs and the anterior center edge angle on false profile radiographs. Therefore, it is recommended to routinely use false profile radiographs for evaluating anterior hip coverage.

Summary: This study retrospectively analyzed pelvic X-rays of 69 patients with symptomatic acetabular retroversion and found a significant increase in posterior pelvic tilt angle from supine to standing position. The features of acetabular retroversion were less evident on standing radiographs. Therefore, supine and standing pelvic X-rays should be used to assess patients with hip impingement symptoms in order to identify signs of acetabular retroversion and optimize acetabular correction during surgery.

Summary: Posterior glenohumeral instability is an often overlooked cause of disability requiring surgical intervention. Even with a well-performed capsulolabral repair, severe posterior glenoid bone abnormalities can still lead to persistent instability. Understanding and recognizing these lesions is crucial for effective surgical decision making and implementation. Various procedures, including recent advancements in arthroscopic grafting techniques, have been developed to address posterior instability. This article aims to provide an evidence-based strategy for diagnosing and managing posterior shoulder instability and glenoid bone loss.

Summary: This study aimed to assess the surface electromyogram (sEMG) signal characteristics of the muscle around the hip joint after Pemberton osteotomy in children with unilateral developmental dysplasia of the hip (DDH). The results showed that children with unilateral DDH who underwent Pemberton osteotomy combined with femoral osteotomy exhibited asymmetry and compensatory increase in sEMG activity of the muscles around the hip joint when standing and walking. Rehabilitation training of the muscles around the hip joint after unilateral DDH should be strengthened.

Summary: This study compared the effects of Salter pelvic osteotomy, Pemberton pelvic osteotomy, and triple pelvic osteotomy on the center of acetabulum and pelvic morphology in children with hip joint disease. The results showed that Salter pelvic osteotomy can increase pelvic height and move the center of acetabulum outward and downward; Pemberton pelvic osteotomy can increase pelvic height and move the center of acetabulum downward; while triple pelvic osteotomy only moves the center of acetabulum downward.

Summary: The purpose of this study was to evaluate the variation of pelvic tilt during total hip arthroplasty (THA), and the results showed that there were significant differences in pelvic tilt among patients in supine, standing, and seated positions. The pelvis rotated posteriorly from standing to seated. Therefore, functional imaging should be performed prior to THA for more accurate surgical planning.

Summary: This study compared the clinical outcomes of treating Crowe III-IV DDH with direct anterior approach (DAA) versus posterolateral approach (PLA). The DAA group showed significant improvements in HHS score, WOMAC score, hip abductor strength, hip flexor strength, and limp recovery compared to the PLA group. Improved clinical outcomes without increased complication risks can be achieved with DAA when surgeons are specialized in this approach.

Summary: This study investigated the relationship between spinal anomalies and functional outcomes in patients with acetabular dysplasia (AD). The results showed that the severity of spinal anomalies measured by radiographic variables was not associated with decreased patient function, but there was a correlation with the function of the contralateral hip.

Summary: This study aimed to investigate spinopelvic and lower limb alignments in a Chinese population and their impact on spinopelvic motion after total hip arthroplasty (THA). The results showed that lower limb compensations were associated with pelvic stability and increased ankle dorsiflexion angle in standing was correlated with a greater degree of posterior pelvic tilt.

Summary: Increased torsional deformity of the femur is a crucial factor in recurrent patellofemoral instability. Distal femoral derotational osteotomy is an effective treatment option for patients with increased femoral torsional deformity. However, groin pain is a rare complication after this surgery.

Summary: This study demonstrates that acetabular deformity is common in OI patients and is associated with disease severity. A considerable number of hips exhibit PPAD, which may not lead to femoroacetabular impingement but can result in anterior uncovering of the hip joint. A superomedial bulging of the iliopectineal line is the most predictive radiographic sign for this pattern of acetabular deformity.

Summary: This study identified significant predictors for cervical myelopathy and hydrocephalus in young children with achondroplasia, providing important parameters for clinical management. The findings suggest that 'Cord constriction ratio' is a key predictor for cervical myelopathy, while 'Frontal horn width' and 'Posterior indentation' grade are crucial predictors for hydrocephalus, which can guide treatment decisions.

Summary: This study compares the kinematics, repeatability, and reproducibility of five multi-segment foot models (MFMs) under the same experimental conditions. The results showed that rotating the segment according to radiographic or goniometric measurements improved reliability. Additionally, there were differences in range of motion and points of peak angle among different models. Therefore, clinicians and researchers need to be aware of the specific features of each MFM to make accurate decisions.

Summary: Fibrodysplasia ossificans progressiva (FOP) is a rare and devastating genetic disease where soft connective tissue turns into heterotopic bone. Although the genetic defect is known, effective treatments have been hindered by the complexity of the disease. Gene therapy shows promise as a therapeutic option for FOP, but the role of the immune system and the primary causative cell remain unknown.

The results showed that these patients often presented with short stature, short limbs, genu varum, hydrocephalus, and developmental delay. After growth hormone therapy, there was a significant increase in height. These findings highlight the importance of monitoring skeletal manifestations and neurodevelopmental status in patients with hypochondroplasia.
