Many types of steel plates are used for internal fixation of calcaneal fractures through extensive lateral approach. The fixation screw at the anterior calcaneal process must be placed into the dense compression trabeculae located directly under the calcaneocuboid articular surface to achieve a stable fixation.
The transverse diameter and inner tilt angle of the calcaneocuboid articular surface were measured and the inner structures near the calcaneocuboid articular surface were observed in forty adult calcaneus bone specimens to provide an anatomical basis for internal fixation of calcaneal fractures.
The transverse diameter was 22.67 ± 2.14 mm and the inner tilt angle was 60.4 ± 7.1°.
Screws should be implanted under the calcaneocuboid articular surface and the length and direction of the screw should be selected according to the transverse diameter of the calcaneal articular surface and the inner tilt angle, respectively.
广泛的外侧入路常被用于跟骨骨折的内固定，术中需要将跟骨前突固定螺钉准确地拧入跟距关节面下的密质骨压缩骨小梁内，以获得稳定的固定。
在 40 例成人跟骨标本上测量跟距关节面的横径和内倾斜角，并观察跟距关节面附近的内部结构，为跟骨骨折的内固定提供解剖学基础。
跟距关节面的横径为 22.67±2.14mm，内倾斜角为 60.4±7.1°。
螺钉应植入跟距关节面下，根据跟骨关节面的横径和内倾斜角选择螺钉的长度和方向。
