The Measurement of the Inclination Angle of the Hamate and Analysis of the Inclination Angle for the Rotation Deformity of the Little Finger in the Fixation of the Carpometacarpal Joint.

Orthop Surg 2021 Jun 10. Epub 2021 Jun 10.

Department of Orthopaedic Surgery, Nanjing First Hospital, Nanjing Medical University, Nanjing, China.

Objective: Complex base fractures of the fifth metacarpal bone and dislocation of the fifth carpometacarpal joint are more prone to internal rotation deformity of the little finger sequence after fixation with a transarticular plate. In the past, we have neglected that there is actually a certain angle of external rotation in the hamate surface of transarticular fixation. This study measured the inclination angle of the hamate surface relative to the fifth metacarpal surface for clinical reference. Read More
