Evaluation of treatment results of perilunate dislocation by open reduction and repair of the scapholunate ligament

Abstract

The study aims to evaluate the treatment results of perilunate dislocations treated with open reduction and scapholunate ligament (SLL) repair. The results showed that the majority of patients had no pain and wrist function was restored well. After surgery, the majority of patients (29 out of 32) had relief from pain. The average wrist motion was 77.93^o extensions, 73.69^o flexions, and the mean grip strength was 41.35±5.15 kg. which was 93.56% of the normal side. There was 26 excellent, 1 good, and 5 satisfactory results. The average follow-up time was 32.35 months. Surgical procedures included open reduction and SLL repair. The average functional score is 81.30 (very good). Thus, open reduction and SLL repair gave satisfactory results to subacute and acute perilunate dislocations of the wrist. This technique achieved a relatively pain-free wrist with good grip strength and average SL distance.
