MANAGEMENT OF PROTRUSIO ACETABULI - OUR EXPERIENCE

Purpose-To make use of a titanium mesh and cemented Total Hip Replacement to reinforce the medial acetabular wall in cases of prosthesis induced mild protrusion acetabuli as a cheaper and effective alternative to other methods. Methods-We present two cases of prosthesis ( Austin Moore ) induced unilateral protrusion acetabuli which were managed with cemented Total Hip Replacement with a flanged cup and a cost effective titanium mesh to reinforce the medial wall, considering their age. Results-The patients had an average Harris Hip Score of 91 and were ambulant without support by the 5th post op day. Six months later the patients are comfortable and have no adverse X ray findings. Conclusion-We consider Mesh reinforcement with cemented Total Hip Replacement to be a cost effective procedure in mild protrusion, as it costs only around 15 USD in addition to the cost of the replacement procedure, as compared to 400 USD for an anti protrusion cage.
