Methods Two cases (4 index fingers) of type A2 congenital brachydactyly were treated by wedge osteotomy in the middle phalanx with the bottom margin on the ulnar side. The finger was fixed with K-wires for six weeks followed by functional exercise. Results Follow-up period was 4 months for one case and 5 years for the other. Deformity of the index fingers was corrected. Range of motion of the distal interphalangeal joints averaged 30°. Pinch and grip was stable. The patients were satisfied with the appearance and function of the fingers. Conclusion Orthopaedic treatment of type A2 congenital brachydactyly can lead to good appearance and better function.
