Contractures of the proximal interphalangeal joint.

Posttraumatic stiffness of proximal interphalangeal joints remains a difficult problem that severely compromises hand function. The emphasis of treatment must be on preventing the problem from developing, which begins within hours of the injury. Effective treatment involves a careful evaluation of the injury and then instituting a rational course of therapy. When surgery is necessary, the operative technique must be precise, and it requires a thorough understanding of the anatomic and pathomechanical factors that cause the contracture. Effective postoperative therapy and rehabilitation are integral parts of any surgical procedure, and they usually continue for many months.
