Abstract:
BACKGROUND:Posterior hip dislocation combined with femoral head fractures easily induced femoral head necrosis, ectopic ossification, osteoarthritis and deep vein thrombosis. Different therapeutic methods should be utilized according to the type of fracture.
OBJECTIVE:To investigate the factors affecting the therapeutic effects and complications fol owing surgery of posterior hip dislocation combined with femoral head fractures.
METHODS:Twenty-eight patients, who had been diagnosed as posterior hip dislocation combined with femoral head fractures in the 101 Hospital of Chinese PLA from September 2004 to May 2010, were enrol ed in this study. According to Pipkin typing, operative approach and the time from injury to surgery, therapeutic effects were evaluated using radiographs and the recovery conditions of hip function (Epstein method), and the occurrence of complications was recorded.
RESULTS AND CONCLUSION:A total of 28 patients were fol owed up from 1 to 5 years, averagely 2.8 years. Using the Epstein method, there were excellent in 6 cases, good in 12 cases, average in 7 cases, and poor in 3 cases, with an excellent and good rate of 64%. The therapeutic effects in patients with Pipkin I and II were good, with excellent and good rates of 100%and 78%, respectively. Moreover, the complications were less, with a rate of 17%and 22%, respectively. The therapeutic effects of patients with Pipkin III and IV were poor, especial y, Pipkin IV patients, whose excellent and good rate was only 20%and the incidence of complications was 80%. No significant difference in the incidence of complications was detected in patients undergoing Smith-Peterson anterior approach and K-L posterior approach (P>0.05). No significant difference in the incidence of complications was detectable among patients from three groups (the time from fracture to operation<12 hours, 12-48 hours, and>48 hours) (P>0.05). Results indicated that the choice of treatment method should be determined by the type of fracture. The prognosis depends on the patient’s age, time of treatment, types of fracture and dislocation, methods of treatment and related measures of prevention of complications.
