Percutaneous corrective osteotomy for Kirner's deformity: a case report.

Kirner's deformity is a rare skeletal deformity first described in Germany in 1927. It is characterized by progressive palmar-radial curvature of the distal phalanx of the small finger. Here, we present the case of a 15-year-old boy with Kirner's deformity in both little fingers, who was treated with percutaneous corrective osteotomy. This was followed by a successful outcome after 36 months.
