Complex Acetabular Prosthetic Revisions. Comparison of modern materials in treatment strategies

The increasing number of total hip arthroplasty (THA) operations has inevitably led to an increase in the number of revisions for aseptic, septic or traumatic mobilization. The surgical treatment of these lesions is a demanding challenge for the surgeon: the primary objective is a stable osterexesis of the fracture that allows an early mobilization of the patient, therefore a careful evaluation of the materials to be implanted is also necessary. The aim of our study is to demonstrate the usefulness and limitations of new revision surgery technologies in cotiprosteal fractures. We enrolled 54 patients who underwent hip acetabular revision. The criteria chosen for the evaluation of outcomes: the visual analogue scale of pain in the traumatized hip (VAS); the subjective score of the Harris HIP Score; quality of life measured with The Short Form (12) Health Survey (SF-12); the average time of cup integration and complications. The evaluation endpoint was set at 24 months. The results, assessed with the aforementioned parameters, were on average good. Complications are the same as those described in the literature. The advantages of the new generation of acetabular components are: excellent integration and ductility of materials during revision of hip arthroplasty
