Effectiveness of Flexor Tenotomy With a Transpositional Skin Flap for the Treatment of Severe Claw Toe Deformity With Mild-to-Moderate Joint Contracture.

Flexor tenotomy is the most effective for achieving healing and for the prevention of toe ulcer resulting from claw toe deformity. Although flexor tenotomy might be effective for a flexible claw toe, it might not provide benefits for severe claw toe deformity involving joint contracture. We devised a method involving the transfer of a flap to the skin defect caused by tenotomy, as severe claw toe deformity is associated with skin contracture. Although transpositional skin flap might increase the postoperative complication risks, it can be effectively used for severe claw toe deformity involving mild-to-moderate joint contracture.
