Traitement chirurgical des luxations et fractures-luxations périlunaires du carpe. Étude rétrospective d'une série de 12 cas

We report a retrospective series of 12 dislocations or perilunate fracture-dislocations having occurred in sportsmen. The results of our series are compared with the data of the literature and we discuss epidemiology, types of lesions, surgical treatment, complications and prognosis of this pathology. The displacement of all these lesions was posterior. The mean age was 24 years. All 12 patients had undergone surgical treatment through a dorsal approach. They were reviewed clinically and radiologically with a mean follow-up of 27 months. The average Cooney functional score was 70 over 100 with two excellent, four good, four fair and two poor results. Average flexion-extension motion arc was 72%, the grip strength was 77% compared to the other wrist. Persistent wrist pain was almost constant.
