Traumatic mechanisms and therapeutic results of the perilunate injuries.

ABSTRACT

OBJECTIVE: In this study, eighteen patients who have had perilunate injury with dislocation or fracture, were evaluated and the patho-mechanics and surgical treatment were studied. SUBJECTS AND METHODS: According to the Green and O'Brien's classification, type 1 injury occurred in one patient, type 2 in nine, type 4A in five, type 4C in one and type 4D in one. The other one case could not be classified using the Green and O'Brien's criteria. RESULTS: According to the Evans scoring system, good results were achieved in thirteen patients, fair results, in four, poor results in one and very poor results in none. When the patho-mechanics was estimated based on the Mayfield's criteria, seventeen patients were classified as stage 3. However only one case was extremely unusual and should be classified as a subtype of stage 2. CONCLUSION: The results were good in the majority of patients who had repair of perilunate injury.
