OBJECTIVE There are limited data on bone dimension and cartilage thickness of the distal humeral articular surface. This study aimed to evaluate sex- and age-related bone dimension and cartilage thickness differences and assess the effect of cartilage thickness on distal humeral shape. DESIGN Elbow magnetic resonance images of 180 healthy participants were evaluated. Cartilage thicknesses of the trochlea and capitellum were measured at 19 points using coronal and axial images. In addition, bone diameters were measured from the flexion-extension axis to the 19 points on the coronal and axial magnetic resonance images. Sex differences were evaluated, and the correlation between age and measurement parameters was assessed. RESULTS Significant sex differences regarding the diameters of the axial trochlear bone, coronal lateral trochlear bone, and medial capitellar bone, cartilage thickness at the apex of the lateral trochlear ridge in the axial and coronal plane and at the most lateral point of the capitellar articular surface in the axial plane were observed. A negative correlation was observed between age and axial plane trochlear bone dimensions and between age and coronal plane lateral trochlear and medial capitellar bone dimensions. No significant correlation was found between cartilage thickness and bone dimensions. CONCLUSIONS Bone dimension and cartilage thickness at the distal humerus vary according to sex and age. The data could be used in the donor site selection and graft preparation while osteochondral autograft transfer and allograft transplantation, and in the development of gender-compatible hemiarthroplasty implants.

肱骨远端的综合冠状和轴向骨尺寸和软骨厚度评估：年龄和性别差异。

目的 关于肱骨远端关节面的骨尺寸和软骨厚度的数据有限。本研究旨在评估与性别和年龄相关的骨尺寸和软骨厚度差异，并评估软骨厚度对肱骨远端形状的影响。设计评估了 180 名健康参与者的肘部磁共振图像。使用冠状和轴向图像在 19 个点测量滑车和小头的软骨厚度。此外，在冠状和轴向磁共振图像上测量了从屈伸轴到 19 个点的骨直径。评估了性别差异，并评估了年龄和测量参数之间的相关性。结果 轴向滑车骨、冠状侧滑车骨的直径存在显着的性别差异，在轴向和冠状面上观察了内侧小头骨、外侧滑车嵴顶点处和轴向平面上小头关节面最外侧点处的软骨厚度。在年龄和轴向平面滑车骨尺寸之间以及在年龄和冠状平面外侧滑车和内侧小头骨尺寸之间观察到负相关。在软骨厚度和骨尺寸之间没有发现显着的相关性。结论 肱骨远端的骨尺寸和软骨厚度因性别和年龄而异。该数据可用于供体部位选择和移植物准备，同时骨软骨移植和同种异体移植，以及性别兼容的半关节置换植入物的开发。在轴向和冠状平面中观察外侧滑车脊顶点处的软骨厚度以及在轴向平面中小头关节面的最外侧点处的软骨厚度。在年龄和轴向平面滑车骨尺寸之间以及在年龄和冠状平面外侧滑车和内侧小头骨尺寸之间观察到负相关。在软骨厚度和骨尺寸之间没有发现显着的相关性。结论 肱骨远端的骨尺寸和软骨厚度因性别和年龄而异。该数据可用于供体部位选择和移植物准备，同时骨软骨移植和同种异体移植，以及性别兼容的半关节置换植入物的开发。在轴向和冠状平面中观察外侧滑车脊顶点处的软骨厚度以及在轴向平面中小头关节面的最外侧点处的软骨厚度。在年龄和轴向平面滑车骨尺寸之间以及在年龄和冠状平面外侧滑车和内侧小头骨尺寸之间观察到负相关。在软骨厚度和骨尺寸之间没有发现显着的相关性。结论 肱骨远端的骨尺寸和软骨厚度因性别和年龄而异。该数据可用于供体部位选择和移植物准备，同时骨软骨移植和同种异体移植，以及性别兼容的半关节置换植入物的开发。
