[Tendoplasty of the fingers and the restoration of the skin-fatty layer of the dorsal surface of the hand in boutonnière contracture].

In the period from 1983 to 1990 operations were conducted on 63 patients with postburn boutonnière contracture of 116 fingers. In 19 patients (42 fingers) tendoplasty of the extension apparatus of the fingers was carried out with simultaneous restoration of the dermatoadipose layer on the dorsal surface of the hand with an inguinal or dermatoadipose graft. In 39 patients the tendon of the extensor digitorum muscle was injured over several proximal interphalangeal articulations. A new method for treating boutonnière contracture is suggested. It is based on restoration of the continuity of the central fasciculus and the normal position of the lateral fasciculi with a single tendon autograft. The suggested method produced good results in 90% of cases, i.e. in all cases in which a sufficient volume of passive movements at the proximal interphalangeal articulation was restored in the preoperative period.
