THE TREATMENT OF CHRONIC FLEXION CONTRACTURES OF THE PROXIMAL INTERPHALANGEAL JOINT

A method of treatment of chronic flexion contractures of the PIP joint is presented, with the results obtained in 19 patients treated betwee n 1989 and 1992 after a follow-up of from 6 to 53 months, The flexion contractures, with an extension deficit which ranged between 70 and 90 degrees, had been present for a period of between 2 months and 24 yea rs. Our treatment program involves the surgical release of the unreduc ible PIP joint followed by the use of static and/or dynamic splints, S urgery is performed using a midlateral approach; the accessory collate ral ligament and the flexor sheath are incised and, after the volar pl ate and check-rein ligaments have been excised, forced hyperextension is applied, The main collateral ligaments are carefully spared and fre ed from the condyle if there are any remaining adhesions. In our 19 pa tients, complete extension of the finger was achieved in 11 cases (57. 9%); in the remaining 8 cases (42.1%) the residual extension deficit r anges from 10 to 15 degrees, In our experience this combined surgical and rehabilitative approach had led to consistently good results with minimal complcations.
