Kirner's Deformity: Juvenile Spontaneous Incurving of the Terminal Phalanx of the Fifth Finger

Abstract

Juvenile spontaneous incurving of the terminal phalanx of the fifth finger is extremely rare. The etiology is still uncertain; the combination of a primary epiphyseal disorder and tendon traction has been stressed. Peroperative biopsy has, apart from an epiphysiolysis, shown changes in accordance with osteochondritis dissecans.

Key words:

• adolescence
• epiphysiolysis
• osteochondritis dissecans
• palmar deviation
