@Article{, title={Surgically Treated Isolated Posterior Wall Fractures of Acetabulum: A Short Term Outcome Study}, author={Ali Bakir Al-Hilli, Mohammed Hatem Salal**, Mohammed Kadhim Hamad}, journal={Iraqi Postgraduate Medical Journal المجلة العراقية للاختصاصات الطبية}, volume={18}, number={3}, pages={188-196}, year={2019}, abstract={BACKGROUND:Isolated posterior wall fractures are common injuries of the acetabulum, anatomical reduction andstable fixation are the goals of operative treatment when indicated, outcomes of surgical treatmentdepend on many patient`s and fracture`s factors.OBJECTIVE:To evaluate the functional and radiological outcomes of surgically treated isolated posterior wallfractures of acetabulum and the effect of patient`s and fracture`s variables on the outcomes in a shortterm follow up.MATERIALS AND METHODS:Prospective study on twenty patient who met the inclusion criteria treated surgically for isolatedposterior wall fractures of acetabulum at Baghdad Medical City Directorate from July 2014 toDecember 2016 with at least one year follow up. All patients were evaluated clinically withModified Merle d`Aubigne score and Harris hip score, and radiologically with Matta`s radiologicaloutcome grading. The effect of gender, BMI, associated dislocation, timing of reduction ofdislocation, timing of surgery, and quality of reduction on the outcomes were evaluated.RESULTS:The mean final Modified Merle d`Aubigne score was 15.65 (range, 8 to 18) with excellent and goodresults in 16 patient (80%), fair and poor results in 4 patients (20%). The mean final Harris hip scorewas 89.2 (range, 65 to 100), with excellent and good results in 16 patient (80%), fair and poorresults in 4 patients (20%).The final radiological outcome results were excellent and good in 17patient (85%), fair and poor in 3 patients (15%). The functional and radiological outcomes weresignificantly affected by the quality of fracture reduction ( p=<0.0001, p=0.0009) respectively. Inaddition, the functional outcome was significantly affected by the presence of dislocation (p=0.019),delay in reduction of dislocation (p=0.0026), and delay in surgery more than 2 weeks (p=<0.0001).However, gender, and BMI did not show clear effects on the functional outcome ( p=0.938,p=0.172) respectively.CONCLUSION:Satisfactory outcomes can be obtained with open reduction and internal fixation of isolated posteriorwall fractures of acetabulum in short term follow up. Anatomical reduction strictly correlated to bothfunctional and radiological outcomes with favorable results. Early reduction of hip dislocationwithin 12 hours and early surgery within two weeks had favorable functional outcome while thepresence of hip dislocation adversely affects the functional outcome. However differences in genderand body mass index did not clearly affected the functional outcome.
