ABSTRACT
Methods@#The study was conducted on 100 adult patients. The patients were randomly allocated into two groups of 50 patients each: group A, autologous fat group, and group B, Gelfoam group. The postoperative follow-up was conducted at intervals of 6 weeks, 3 months, 6 months, and 12 months. Both groups were evaluated clinically (Oswestry Low Back Pain Disability Questionnaire [ODI], Visual Analog Scale [VAS], Straight Leg Raising Test [SLRT]) and radiologically (using Ross grading by contrast magnetic resonance imaging [MRI]) for development of radicular pain and hence EF. @*Results@#Based on the analysis, improvement in mean values of ODI score, VAS score, and SLRT were found to be statistically significant postoperatively at intervals of 6 weeks, 3 months, 6 months, and 12 months when compared individually in both groups. However, improvement was greater in the autologous fat group than in the Gelfoam group. Based on contrast-enhanced MRI, the number of patients who developed EF was smaller in the autologous fat group than in the Gelfoam group. @*Conclusions@#In the present study, on clinical and radiological assessment, we conclude that both groups prevent radicular pain and postoperative EF individually but relatively autologous fat was found to be more effective than Gelfoam in the prevention of EF and hence radicular pain.
ABSTRACT
<p><b>PURPOSE</b>Complete visualization of certain acetabular fractures of posterior wall or column with cranial extension involving superior dome from standard surgical exposures is a challenge. Osteotomy of the greater trochanter has been used to enhance fracture visualization, especially the dome, in posterior and lateral exposures of the acetabulum. It also decreases the need for excessive muscle retraction. The purpose of the study was to investigate the outcome associated with trochanteric flip osteotomy in the management of certain acetabulum fractures.</p><p><b>METHODS</b>From January 2011 to December 2013, 25 displaced acetabular fractures were treated by open reduction and internal fixation. The fractures were managed using a Kocher-Langenbeck approach along with trochanteric flip osteotomy. At 3rd, 6th and 24th month follow-up, all patients had radiographic examination and underwent a final clinical evaluation based on the modified Merle d'Aubigne and Postel score. The strength of the abductors was assessed according to the Medical Research Council (MRC) grading system.</p><p><b>RESULTS</b>Congruent reduction was achieved in all patients and all osteotomies healed within an average period of 3.8 months. All our patients were allowed full weight bearing at the end of 3 months and with no abductor lurch at the end of 6 months follow-up. There were no cases of avascular necrosis of femoral head. None of the patients had any neurovascular complication or infection by the end of the follow-up period.</p><p><b>CONCLUSION</b>Trochanteric flip osteotomy is a very effective technique to fix certain acetabular fractures especially those with dome involvement. It is more accurate and associated with no significant complications compared with conventional way.</p>
