Corrective Step-cut Osteotomy at the Affected Bone for Correction of Rotational Deformity Due to Fracture of the Middle Phalanx.

Malunion at the shaft of the middle phalanx yields less functional problems compared with malunion at the shaft of the proximal phalanx and metacarpal bones. In the present report, the patient sustained a minimally displaced fracture at the distal portion of the distal middle phalanx of the ring finger spraining the finger during playing flag football. Fracture was treated conservatively and fracture union was completed. However, the patient complained of functional problems in activities of daily living due to the malrotational deformity of the finger. We treated the malrotational deformity close to the distal interphalangeal joint of the middle phalanx with step-cut osteotomy at the affected bone successfully.
