Outcomes of Secondary Combined Proximal Interphalangeal Joint Release and Zone II Flexor Tenolysis

Background: Tendon adhesions and capsular contractures following trauma to the proximal interphalangeal joint (PIPJ) may significantly reduce hand function. Traditional, staged surgical management prioritizes restoration of PIPJ passive range of motion with joint release prior to restoration of active range of motion (AROM) with tenolysis. This is expensive and burdensome for patients. Our objective was to evaluate functional outcomes of combined PIPJ release and zone II flexor tenolysis. Methods: We retrospectively reviewed patients who underwent combined PIPJ release and flexor tenolysis. Replantation and tendon graft cases were excluded. Data were collected on pre- and postoperative AROM, total active motion (TAM), tip to distal palmar crease (DPC) distance, and grip strength. Functional outcomes were graded using the Boyes, American Society for Surgery of the Hand, and modified Strickland scores. Results: Twelve patients (9 men and 3 women, median age = 40 years) with a total of 15 digits underwent co...
