[Surgical treatment for boutonniere deformity of the fingers. Retrospective study of 47 patients].
Disruption or laceration of the central slip of the extensor tendon at the proximal interphalangeal (PIP) joint with volar displacement of the lateral bands can result in the so-called boutonniere deformity which includes loss of extension at the PIP joint and compensatory hyperextension of the distal interphalangeal (DIP) joint. Many procedures has been described in the literature and no standard treatment can be recommended. The authors reports a series of 47 cases of posttraumatic boutonniere deformity. ⋯ Supple boutonniere deformity must always be treated by initial physical therapy. Surgical procedure with reconstruction of the extensor apparatus is satisfactory if the PIP joint is normal. When there is PIP osteoarthritis, it may be beneficial to perform a two-stage technique with tenoarthrolysis followed hand therapy and a secondary reconstruction of the extensor apparatus as these last procedure give satisfactory results on a supple boutonniere deformity.
