Summary
Callus distraction using external fixators effectively lengthened metacarpals and phalanges in 14 patients. This bone lengthening technique showed high patient satisfaction and functional improvement, with one case of non-union.
Area of Science:
- Orthopedic surgery
- Regenerative medicine
- Biomechanical engineering
Background:
- Limb length discrepancy can result from trauma or congenital conditions.
- Surgical intervention is often necessary to restore function and aesthetics.
- Callus distraction osteogenesis is a established method for bone lengthening.
Purpose of the Study:
- To evaluate the efficacy and outcomes of callus distraction for lengthening metacarpals and phalanges.
- To assess patient satisfaction and functional improvement after the procedure.
- To identify potential complications associated with metacarpal and phalangeal lengthening.
Main Methods:
- Retrospective review of 14 patients undergoing metacarpal/phalangeal lengthening between 1992 and 1999.
- Utilized the callus distraction technique with a small external fixator (Orthofix).
- Indications included traumatic amputation, aplasia, and hypoplasia.
Main Results:
- Median lengthening achieved was 21 mm (82% of original length).
- Median follow-up was 39 months, with high patient satisfaction reported.
- Functional improvement was observed in 13 out of 14 patients; one patient experienced non-union.
Conclusions:
- Callus distraction is a viable technique for lengthening metacarpals and phalanges, offering significant functional benefits.
- The procedure is generally well-tolerated, leading to high patient satisfaction.
- Non-union remains a potential complication requiring careful monitoring and management.
