The introduction provides an in-depth understanding of the acetabulum's anatomical structure and its significance in hip joint biomechanics. It highlights the variability in acetabular morphology among normal individuals, emphasizing the importance of establishing normal ranges for accurate diagnosis of acetabular deformities. The section also underscores the role of geographical, racial, and anatomical factors in influencing acetabular parameters, crucial for orthopedic interventions and surgical outcomes like total hip arthroplasty. Furthermore, it discusses the limitations of traditional imaging methods and the necessity of advanced techniques like computed tomography (CT) scans for precise evaluation and preoperative planning in hip surgeries.
The study adopted a cross-sectional design at a tertiary care center, enrolling 94 participants using purposive sampling for CT evaluation of acetabular morphology. Morphometric parameters including center edge angle of Wiberg, acetabular angle of Sharp, acetabular version, acetabular depth, and joint space width were measured using CT scans, while BMI categorization and statistical analyses were conducted to explore gender-based and side-based differences and correlations with BMI and age.
The study included 94 patients with ages ranging from 20 to 82 years (mean age: 49±15 years), predominantly in the 41-50 years age group. Female participants slightly outnumbered males. The mean BMI was 23.5±3.2 kg/m, with variations across different age and BMI categories. Most morphometric parameters showed no significant differences between sexes or sides but did correlate with age and BMI, notably the center edge angle positively correlating with BMI in males.
The study found correlations between morphometric parameters of the acetabulum and both age and BMI. Specifically, the center edge angle demonstrated a positive correlation with BMI in males and a weak positive correlation with age. Acetabular angle showed a negative correlation with BMI, highlighting potential implications for understanding hip joint health and conditions related to BMI changes.
引言部分深入介绍了髋臼的解剖结构及其在髋关节生物力学中的重要性。它强调了正常个体髋臼形态的变异性，强调了建立正常范围对于准确诊断髋臼畸形的重要性。该部分还强调了地理、种族和解剖因素在影响髋臼参数方面的作用，这对于骨科干预和全髋关节置换等手术结果至关重要。此外，它讨论了传统成像方法的局限性以及计算机断层扫描（CT）等先进技术在髋关节手术精确评估和术前规划中的必要性。
本研究在一家三级医疗中心采用横断面设计，通过目的抽样招募94名参与者进行髋臼形态的CT评估。使用CT扫描测量包括Wiberg中心边缘角、Sharp髋臼角、髋臼前倾角、髋臼深度和关节间隙宽度在内的形态学参数，同时进行BMI分类和统计分析，以探讨基于性别和侧别的差异以及与BMI和年龄的相关性。
该研究纳入了94名年龄在20至82岁之间（平均年龄：49±15岁）的患者，主要集中在41至50岁年龄组。女性参与者略多于男性。平均BMI为23.5±3.2kg/m，在不同年龄和BMI类别中存在差异。大多数形态学参数在性别或侧别之间没有显著差异，但与年龄和BMI相关，特别是男性的中心边缘角与BMI呈正相关。
该研究发现髋臼形态学参数与年龄和BMI之间存在相关性。具体而言，男性的中心边缘角与BMI呈正相关，与年龄呈弱正相关。髋臼角与BMI呈负相关，这突出了对理解髋关节健康以及与BMI变化相关疾病的潜在意义。
