[Use of a distraction apparatus in complex treatment of osteoarticular paronychia and osteoarthritis of metacarpophalangeal joints].

Experience in the treatment of 41 patients with osteoarticular paronychia and 14 patients with osteoarthritis of the metacarpophalangeal articulations is discussed. The treatment consists in arthrotomy, careful curettage of the tissues of the involved articulation and its through drainage, application of a primary suture to the wound, and application of a distraction apparatus. Graded distraction of the articulation ensures its decompression, which prevents progression of bone destruction and creates favorable conditions for regeneration of the articular ends, and prevents the formation of coarse cicatricial adhesions and ankylosis. All these measures make it possible to restore the function of the affected articulation.
