Dislocation Rate Fallowing Posterior Total Hip Arthroplasty with Intra-Osseous Soft Tissue Repair

Background: The commonly used approaches for THR include; Anterior Approaches.(Smith-Petersen); Anterio-lateral approaches; Posterior Approaches.(Osborne, & Moore); Medial Approach (Ferguson; Hoppenfeld and deBoer); Posterolateral Approach (Gibson); & Lateral Approaches (Watson-Jones, Harris, McFarland and Osborne, Hardinge, Hay as described by McLauchlan). 1Posterior approach to the hip is famous to associated with higher dislocation rate of 4.5% 2 compare to 0.0% for the anterior approach.Other surgeon describe the marked reduction in the rates fallowing tissue repair from 6.38% to 0.0%.2,3 We conduct the study design to determine dislocation rate following total hip arthroplasty using posterior approach and intra-osseous repairs of short rotatorsPatient & methods: A prospective, descriptive, hospital based longitudinal study design is conducted in Elribat University Hospital from June 2013 to June 2014 in which all patient operated for THA via posterior approach using intra-osseous soft tissue repair with size 2 nylon during study duration in Elribat University Hospital is included in study.Patients fallowed 6 month postoperatively using Harris hip score.Results: The study includes 31 hips.Four patients were lost to follow up due to; death (cardiac disease 3rd week post-operative), deep infection (7 th post-operative day) & loss of contact.So the total remaining number were 27 hips with; 17 male (62.96%) & 10 female (37.04%).The analysis of data shows that no reported hip dislocation. Conclusion:The high dislocation rate fallowing THR via posterior approach is markedly reduce if it fallowed by proper soft tissue repair to greater trochanter using strong suture.
