The functional results of ulnar nerve repair. Defining the indications for tendon transfer

The subjective, objective and functional outcome following repair of isolated ulnar nerve injuries was assessed in 50 patients, 1 to 7 years after repair. We tried to identify those patients who may benefit from early tendon transfer. This study confirmed a satisfactory functional result in sedentary workers, but not in manual labourers. Intrinsic muscle power, grip strength, key pinch and sensation continued to improve following repair of high injuries for at least 2 years, and of low injuries for at least 3 years. Early tendon transfers are only recommended in manual workers who complain of poor grip or key pinch.
