Concomitant Injuries Affect Prognosis in Patients with Central Slip Tear

Central slip tears often occur with concomitant hand injuries. However, the outcome of a central slip tear and the effect of concomitant injuries are rarely reported. We evaluated 67 fingers in 63 patients with central slip tears who underwent primary surgery in our hospital between April 2009 and June 2017. We performed multivariate analyses; on proximal interphalangeal joint active range of motion and existing extension lag greater than 10 degrees as dependent variables, and age, existence of concomitant fractures, skin defects, collateral ligament injuries, ruptured lateral bands, ruptured flexor tendons, or vascular injury in the injured finger as independent variables.
