Extensor tendon dislocation of the hand: six cases in a family

Abstract

Dislocation of hand extensor tendons (ETD) is relatively uncommon. Among four types of ETD (degenerative, traumatic, spontaneous and congenital), congenital dislocations are rarer and can be seen alone or in association with other diseases (Inoue and Tamura 1996; Ozcanli et al., 2012; Tanabe et al., 2011; Ishizuki, 1990). Extensor tendon dislocations in the same family have not been reported before. We present six cases in a family with atraumatic extensor tendon dislocations on their 16 extensor tendons
