Summary
Painful posttraumatic scaphoid malunion, a hump-back deformity, can cause wrist instability and limited motion. An experimental osteotomy with bone graft and screw fixation effectively corrected the deformity, improving carpal alignment and wrist function.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Trauma Surgery
Background:
- Scaphoid malunion, specifically hump-back deformity, can lead to significant wrist dysfunction.
- Dorsal intercalated segmental instability (DISI) is a common complication of scaphoid malunion.
- Limited wrist motion and pain are hallmark symptoms.
Observation:
- Two cases of painful posttraumatic scaphoid malunion with DISI deformity were analyzed.
- Patients presented with significant limitations in wrist range of motion.
- Preoperative assessment revealed characteristic scaphoid angulation and shortening.
Findings:
- An experimental opening wedge scaphoid osteotomy utilizing an iliac bone graft and Herbert screw fixation was performed.
- The surgical intervention effectively corrected scaphoid deformities, including angulation and shortening.
- Postoperative outcomes demonstrated improved carpal alignment and restored wrist motion.
Implications:
- This surgical technique offers a viable solution for correcting complex scaphoid malunions.
- Restoration of carpal alignment and wrist function can significantly improve patient quality of life.
- Further research may validate this approach for broader clinical application in scaphoid reconstruction.
