The carrying angle of the elbow is a critical aspect of upper limb biomechanics, influencing arm movement, and hand precision. This study aims to assess elbow joint parameters, including the carrying angle, articular surface angle, and anatomical alignment to understand normal elbow morphometry and its variations based on age, sex, and side dominance.
The study included 300 right-hand dominant, healthy volunteers aged 18-50 years. Elbow joint measurements were taken using anteroposterior (AP) and lateral radiographs. The carrying angle, articular surface angle, and other anatomical parameters such as the anterior humeral line (AHL) and radiocapitellar line (RCL) were measured.
The mean carrying angle on the dominant side was 10.19 ± 1.175° for males and 13.44 ± 0.610° for females, ( < 0.001). On the non-dominant side, males had a mean carrying angle of 9.72 ± 1.063°, and females had 13.38 ± 0.634°, also showing significant differences ( < 0.001). The articular surface angle was 82.8° ± 4.501°. The AHL intersected the capitellum in the middle third in 55.3% of dominant sides and 55% of non-dominant sides. The mean trans-epicondylar distance was 6.19 cm on the dominant side and 6.21 cm on the non-dominant side.
This study provides valuable data on elbow joint anthropometry in the Central Indian population, revealing significant sex-based differences in carrying angle and alignment.
肘关节提携角是上肢生物力学的一个关键方面，影响手臂运动和手部精细动作。本研究旨在评估肘关节参数，包括提携角、关节面角度和解剖对线，以了解基于年龄、性别和优势侧的正常肘关节形态及其变异。
本研究纳入了300名年龄在18至50岁之间、右利手的健康志愿者。使用前后位（AP）和侧位X线片对肘关节进行测量。测量了提携角、关节面角度以及其他解剖参数，如肱骨前线（AHL）和桡骨头线（RCL）。
优势侧男性的平均提携角为10.19±1.175°，女性为13.44±0.610°，（<0.001）。非优势侧男性的平均提携角为9.72±1.063°，女性为13.38±0.634°，也显示出显著差异（<0.001）。关节面角度为82.8°±4.501°。在优势侧的55.3%和非优势侧的55%中，AHL在小头骨中部三分之一处相交。优势侧的平均髁上距离为6.19 cm，非优势侧为6.21 cm。
本研究提供了关于印度中部人群肘关节人体测量学的宝贵数据，揭示了提携角和对线方面基于性别的显著差异。
