Summary: The study found that cam morphology was predominantly seen in males and was associated with radiographic hip osteoarthritis and hip pain. Cam morphology was more strongly associated with inferior femoral head osteophytes than those at the superior femoral head and acetabulum in both males and females.

Summary: This study utilized statistical shape modeling to evaluate the relationship between hip shape and the severity of hip osteoarthritis (HOA). The results revealed that cam morphology and acetabular dysplasia were features of severe HOA, while they were unrelated to moderate disease, suggesting potential prognostic utility.

Summary: This study evaluated the biomechanical effectiveness of 3D-printed integrated acetabular prosthesis (IAP) and modular acetabular prosthesis (MAP) in reconstructing the acetabulum for patients with Crowe III developmental dysplasia of the hip (DDH). The results showed that IAP had a lower risk of loosening and fracture, as well as better long-term stability compared to MAP.

Summary: Long-term follow-up studies have shown that surgically treated DDH children may develop premature osteoarthritis on both affected and unaffected hips. Gait analysis revealed higher loading rates on both sides of the hip, which were correlated to acetabular index and peak unloading rates. Regular assessment of hip morphology and loading rates is crucial for early identification of hip dysplasia and cartilage degeneration risk.

Summary: This study compared the measurements of acetabular parameters from two commonly used software systems and found significant differences in estimating the percentage of femoral head coverage, with CG software more likely to reflect true values. Pelvic tilt and Delta PelvicTilt were identified as influencing factors in the differences between software outputs.

Summary: This research aimed to use a computer method to calculate the Hip Congruency Index (HCI) to objectively estimate radiographic hip congruency. The results showed that HCI is capable of estimating hip congruency associated with HD and can improve the accuracy of diagnosis when used in conjunction with other evaluation parameters.

Summary: The relationship between acetabular dysplasia and spino-pelvic alignment was explored in this study. The results showed no significant association between acetabular dysplasia and spino-pelvic parameters, but a higher pelvic incidence may be a factor associated with acetabular dysplasia.

Summary: This study aimed to establish a reference value for the anterior center edge angle (ACEA) in preoperative planning for periacetabular osteotomy (PAO), investigate the effects of pelvic rotation and inclination on measured ACEA from false profile (FP) radiographs, and determine the appropriate range of positioning for FP radiographs through detailed simulations.

Summary: Residual hip dysplasia can still be present despite appropriate treatment of congenital hip dysplasia. Detection of residual dysplasia requires follow-up and additional imaging investigations. Early treatment is crucial for improving the condition, and the decision for surgery should be based on radiographic criteria and additional imaging findings.

Summary: This retrospective cohort study evaluated the outcomes of 65 older individuals who underwent total hip arthroplasty (THA) with a ceramic acetabular component device for hip osteoarthritis. The results showed that two years after surgery, the positioning angles of the acetabular and femoral components remained stable, and there was increased functionality and joint mobility with reduced pain. The rate of complications was low.

Summary: This study compared the symmetry of clinical and radiographic signs in police working dogs with bilateral hip osteoarthritis. The findings showed significant correlations between weight distribution, age, and radiographic abnormalities, particularly with circumferential femoral head osteophyte (CFHO) on the right limbs.

Summary: This study investigated the variability of 3D hip morphology in patients with borderline acetabular dysplasia, and determined the correlation between plain radiographic parameters and 3D coverage. The results showed highly variable 3D deformities in patients with borderline acetabular dysplasia, including anterior, lateral, and posterior acetabular coverage. Plain radiographic assessments were poorly correlated with anterior 3D coverage on low-dose CT.

Summary: This study analyzed the cellular composition and functionality differences between acetabular and femoral bone marrow cells in hip osteoarthritis (OA) patients. The results showed that acetabular bone marrow had a higher frequency of T-lymphocytes and fibroblastic potential, while femoral bone marrow had higher frequencies of B-lymphocytes and myeloid cells. In addition, acetabular mesenchymal stromal cells exhibited a senescent profile. These findings provide important insights into the characteristics of acetabular bone marrow cell populations and the pathogenic mechanisms of OA.

Summary: The study evaluated the outcomes of total hip arthroplasty (THA) in patients with post-traumatic osteoarthritis (OA) and avascular necrosis (AVN), who had previously undergone surgical treatment for acetabular fractures. THA significantly improved the life quality and functional status of patients with post-traumatic OA and AVN.

Summary: This study aimed to compare the full circumference acetabular coverage angle (ACA) in patients with developmental dysplasia of hip (DDH) before and after curved periacetabular osteotomy (CPO) treatment. The results showed that CPO improved the anterosuperior coverage of the femoral head but reduced its inferior coverage. The radar chart was useful for three-dimensional pre-postoperative evaluation of acetabular coverage.

Summary: This study investigated the accuracy and clinical outcomes of percutaneous pelvic screw placement (PPSP) using real-time 3D fluoroscopic navigation in a hybrid operating room for older patients with fragility fracture of the pelvis (FFP). The results showed that this method was accurate and useful for early mobilization and pain relief among older FFP patients.

Summary: Secure fixation is crucial when using a half-pin inserted into the iliac crest as a pelvic external fixator. However, the accuracy of half-pin insertion is challenging due to variations in iliac bone thickness based on its location. This report presents a case of pelvic external fixation for a pediatric pelvic fracture, where precise preoperative planning for half-pin insertion was achieved using a preoperative three-dimensional CT scan guided by an intraoperative support device referencing the functional pelvic plane.
