BACKGROUND: Incidence of traumatic hip dislocation have ween increased with development of transportation. Traumatic hip dislocation demands early recognition as an emergency and prompt reduction. So we designed this study to determine what kinds of factors affect the prognosis of the patient.
Eighty five patients who admitted emergency department of our hospital with the traumatic hip dislocation were enrolled in this study. Cause of injury, type of dislocation, method of reduction, the time from dislocation to reduction, age, gender and associated patellar injury were evaluated by retrospective chart reviews.
Average age of excellent and good group(E&G) is 28+/-17.8 and fair and poor group(F&P) is 39+/-18.6, so the older the age the more poor prognosis(P<0.05). The time to take reduction of E&G group is 18+/-8.2 hours and F&P group is 25+/-12.6 hours, so the faster the better prognosis(P<0.05). We classify the type of hip dislocation by Thompson and Epstein method, type I to type V. The prognosis of type I is better than type V(P<0.05). Fifty five case were associated with patellar injury and they had poor prognosis than the other cases that were not associated with knee joint injury.
In traumatic dislocated hip patients, the prognosis was poor in old age, delay in reduction, higher type of dislocation and associated with knee joint injury.
