Operative treatment of old acetabular fractures / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To explore the operative methods and effects of treatment of old acetabular fractures.</p><p><b>METHODS</b>From October 2001 to October 2007, 26 patients with old acetabular fractures were treated with operation including 21 males and 5 females with an average age of 34 years ranging from 18 to 65 years. On the basis of the three-dimensional computed tomography, all cases were diagnosed and classified according to Letourne-Judet classification, 9 cases were posterior wall fracture, 3 cases were lateropulsition fracture, 7 cases were lateropulsition and posterior wall fracture, 2 cases were posterior column and posterior wall fracture, 2 were T-shape fracture, 3 were dual column fracture. These patients were treated through the anterior,posterior, combined anterior-posterior approaches. The time from injured to operation was 33 to 141 days (averaged 36.4 days). All the fractures were fixed with screws and AO reconstruction plates.</p><p><b>RESULTS</b>All patients were followed up for 6 to 96 months, with an average time of 32.4 months. Evaluated according to Matta criteria, the results of scores was (5.04 +/- 1.04) on pain, (5.23 +/- 0.76) on range of motion, (4.92 +/- 1.16) on walking,and tatal (5.06 +/- 0.99) on average; The functional results of hip joints were excellent in 6 cases, good in 10 cases, fair in 6 cases, and poor in 4 cases. Sciatic nerve injury was found in 2 patients,lateral femoral cutaneus nerve injury in 3 patients, necrosis of femoral head in 1 patient,infection in 1 patient, and ectopic bone formation in 6 patients.</p><p><b>CONCLUSION</b>Good clinical results can be obtained by careful selection of operative indications of old acetabular fractures in combination with proper operative approach and correct reduction and fixation.</p>
