Abstract

A special anatomic locking bone plate for peripherical joint fusion of foot bone and talus comprises a first locking plate and a second locking plate; a first locking screw hole, a second locking screw hole and a third locking screw hole are formed on the first locking plate in sequence from left to right; a fourth locking screw hole, a fifth locking screw hole and a sixth locking screw hole are formed on the second locking plate in sequence from left to right; the first locking plate at the first locking screw hole is connected with the second locking plate at the fourth locking screw hole through a first bone plate; the first locking plate at the second locking screw hole is connected with the second locking plate at the sixth locking screw hole through a second bone plate; and both the first bone plate and the second bone plate incline outwards. The anatomic locking bone plate conforms to surface configuration of bones of the peripherical joints of normal foot bone and talus of a healthy Chinese, and ensures the angle stability after joint fusion.

Description

(1) Technical field [0001] The invention relates to an external fixation support for fingers and palms. (2) Background technology [0002] Post-traumatic arthritis of the peritalar joints has always been a difficult point in the treatment of trauma orthopedics, especially the surgical treatment of peritalar joint fusion, which has a high complication rate and disability rate. Strict peritalar joint fusion requires thorough removal of the articular surface and firm fixation. Especially when the bone fragments are split or collapsed, the currently used hollow nails, saddle nails, or ordinary steel plates often fail to achieve the expected therapeutic effect, and fusion loosening and fixation failure are prone to occur. [0003] It is precisely because of the need for treatment that we have become increasingly aware that there is a lack of exclusive anatomical internal fixators for the special type of peritalar fusion surgery. Therefore, it is necessary to design an internal ...
