Abstract
Objective: To present the results and complications of a series of phalangeal malunion patients.
Materials and Methods: A retrospective study was conducted on phalangeal malunion patients treated with an osteotomy at the deformity site and stabilized with rigid internal fixation. Postoperative mobility of the digit was recorded. The subjective assessment used the Disabilities of the Arm, Shoulder and Hand (DASH) score and a Visual Analogue Scale (VAS) to rate their function and pain at rest and during activity.
Results: Twelve patients (13 phalanges) met the inclusion criteria. The average time between fracture and osteotomy was 14 months and the mean follow-up was 34 months. Final mobility in flexo-extension was: 89 degrees for metacarpophalangeal joint, 74 degrees proximal interphalangeal joint, 54 degrees distal interphalangeal joint. The average VAS pain score was 0 at rest and 1 during activity, and the average function was 7 points. The average DASH score was 6. There were no cases of nonunion. Five patients required plate removal. No patients with articular osteotomy presented signs of Osteoarthritis.
Conclusions: Phalangeal osteotomy at the deformity site is an effective procedure with good objective and subjective short-term outcomes. Patients should be warned about the possibility of a second procedure in cases of plate fixation due to a higher complication rate associated with plate and screw fixations.
