Fractures of fingers and metacarpals are among the most frequent injuries. Many fractures can be successfully treated conservatively. Nevertheless, various malformations, such as malrotation, spur development, bone shortening, deviation of the axis and combinations of these individual deformities may appear in the course of time. Corrective osteotomy can correct these deformities with clinically impaired function and improve/optimize hand function. Prerequisites for corrective osteotomy are a precise analysis of the deformity, precise osteotomy, exercise stable osteosynthesis and intensive follow-up treatment of the hand. Complications, such as implant failure, postoperative tendon and joint adhesions, joint contracture and nonunion are however possible.
