Anthropometric measurements of the distal femoral fragment play a crucial role in prosthesis design during arthroplastic knee surgeries and offer valuable clues for stature estimation in forensic investigations. The present study is an attempt to assess various anthropometric parameters of the distal femur in this regard.
A total of 96 intact dry femora were anthropometrically assessed using digital Vernier calipers. The femoral length was measured using an osteometric table. The torsion angle was calculated with an analog goniometer. The various parameters studied included: medial condyle length and thickness, lateral condyle length and thickness, bicondylar width, intercondylar width, intercondylar depth, torsional angle, and femoral length. The data obtained were statistically analyzed using SPSS software (IBM Corp., Armonk, NY, USA).
Mean medial condyle length was 57.38±4.47mm and thickness was 24.53±2.27mm. Mean lateral condyle length and thickness were found to be 58.49±4.3mm and 25.33±3.15mm respectively. Mean bicondylar width was 71.96±6.73mm, mean intercondylar width 21.86±2.71mm, and the intercondylar depth 27.04±2.59mm respectively. The average femur length was 41.87±3.31mm and the average torsion angle was 20.19°±6.99°. Significant correlations were observed between distal femoral parameters. Lateral condyle length showed maximum correlation with other parameters. Femur length was found to correlate significantly with all parameters except medial condyle thickness. Torsion angle was significantly correlated with lateral condyle length and femur length only.
The findings of this study show considerable variation from those of other studies done within India. This proves that distal femoral anthropometry has regional variations. These data can aid sports physicians and orthopedic surgeons with implant designing and forensic experts during investigations.
股骨远端碎片的人体测量在膝关节置换手术的假体设计中起着至关重要的作用，并为法医调查中的身高估计提供有价值的线索。本研究旨在评估这方面股骨远端的各种人体测量参数。
使用数字游标卡尺对96根完整的干燥股骨进行人体测量评估。使用骨测量表测量股骨长度。用模拟量角器计算扭转角。研究的各种参数包括：内侧髁长度和厚度、外侧髁长度和厚度、双髁宽度、髁间宽度、髁间深度、扭转角和股骨长度。使用SPSS软件（美国纽约州阿蒙克市IBM公司）对获得的数据进行统计分析。
内侧髁平均长度为57.38±4.47mm，厚度为24.53±2.27mm。外侧髁平均长度和厚度分别为58.49±4.3mm和25.33±3.15mm。双髁平均宽度为71.96±6.73mm，髁间平均宽度为21.86±2.71mm，髁间深度为27.04±2.59mm。股骨平均长度为41.87±3.31mm，平均扭转角为20.19°±6.99°。观察到股骨远端参数之间存在显著相关性。外侧髁长度与其他参数的相关性最大。发现股骨长度与除内侧髁厚度外的所有参数均显著相关。扭转角仅与外侧髁长度和股骨长度显著相关。
本研究结果与印度国内其他研究结果有很大差异。这证明股骨远端人体测量存在区域差异。这些数据可为运动医学医生和骨科医生进行植入物设计以及法医专家在调查过程中提供帮助。
