BackgroundThe objective of this clinical study was to evaluate sensory and motor functions in the later period following primary repair of combined injuries of the ulnar and median nerves in the forearm at proximal, middle, and distal levels.MethodsLater period sensory evaluation of ulnar and median combined cuts was performed using two-point discrimination and monofilament tests. On the other hand, motor evaluation was performed by determining dorsal palmar interosseus strength for the ulnar nerve and abductor pollicis brevis muscle strength for the median nerve. Cold intolerance, object recognition, and weight discrimination were also reviewed.ResultsIn total, 26 patients with ulnar-median combined cut and aged between 5 and 59 years were included in this study. Although no deficiency was observed in the sensory functions of any of the patients, a decrease in tactile sensation was detected in the median sensory region in 12 (46%) patients and in the ulnar sensory region in 7 (26%) patients. The most significant loss in terms of motor functions was detected in the opposition pinch strength. Two patients developed claw hand and two showed joint contracture.ConclusionIdeal treatment for peripheral nerve injuries should be primary repair. Restoration of the motor function in the median nerve is relatively easier than that in the ulnar nerve. No significant difference was observed in terms of sensory function. An alternative is needed for primary repair because of lack of motor function in proximal ulnar incisions. There is no standardization of tests performed for peripheral nerve repair.
