Fenestration operation for treatment of acetabular parastyle fracture combined with articular facet compression and collapse of acetabular top involving weight-bearing dome / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the fenestration operation for treatment of acetabular parastyle fracture combined with articular facet compression and collapse of acetabular top involving weight-bearing dome.</p><p><b>METHODS</b>From July 2005 to February 2007, 52 cases of acetabular parastyle fracture combined with articular facet compression and collapse of acetabular top involving weight-bearing dome were treated by two methods. Among them, 24 cases were treated by fenestration operation for articular facet reduction, bone grafing, anatomical reconstruction of the acetabular parastyle with internal fixation, included 17 males and 7 females with an average age of (35.2 +/- 6.4) years old; the other 28 cases were treated only anatomical reconstruction of the acetabular parastyle with internal fixation, included 19 males and 9 females with an average age of (36.4 +/- 4.8) years old. All the patients were evaluated with modified d'Aubigne-Postel clinical evaluation standard.</p><p><b>RESULTS</b>All patients gained bone healing. There were only 1 patient occurenced femoral nerve injury and recovered 2 months later. There were no other complications. All patients were followed up from 12 to 51 months (averaged in 31.5 months). According to modified d'Aubigne-Postel clinical evaluation standard, there were statistic difference between the two groups of patients in pain, walking, range of motion and total score. In fenestration operation group, the results were excellent in 13 patients, good in 9, fair in 1, poor in 1; in parastyle reduction group,the results were excellent in 9 patients, good in 11, fair in 6, poor in 2 (u=0.613, P<0.05).</p><p><b>CONCLUSION</b>Fenestration operation for treatment of acetabular parastyle fracture combined with articular facet compression and collapse of acetabular top involving weight-bearing dome is a feasible method for the recovery of hip joint function.</p>
