[Clinic peculiarities of secondary flexion contractur formation in the proximal interphalangeal joint of the triphalanger fingers in conditions of posttraumatic chronic ischemia].

Occurrence of the proximal interphalangeal (PIP) joints contracture is a characteristic consequence of traumas of a forearm and a hand, complicated by the phenomena of a chronic ischemia. Their formation leads to occurrence of considerable functional deficiency of a hand, especially at involving in process of several fingers, and treatment is a complicated problem. Secondary contractures of PIP joints at a chronic ischemia of a hand and fingers differ high severity level, firmness, are characterized by fast formation and progressing. Elimination of the primary factor of blocking of a kinematic chain at a chronic ischemia of a hand and fingers does not render influence on reduction secondary contractures of PIP joints and leads to necessity of performance of additional surgery.
