Revising a well fixed uncemented acetabular component is challenging. The host bone is often compromised, and the problem is made worse when there has been an adverse reaction to metal debris. This can be associated with extensive osteolysis and soft tissue damage. We are seeing increasing numbers of these difficult cases caused by failure of metal on
metal hip resurfacing and replacement.
The goals of surgery are to reconstruct bone defects, gain immediate primary stability and to encourage early bone in-growth. We have used the Lima Trabecular TitaniumTM system to revise failed metal on metal hip arthroplasty, and in complex primary hip replacement. The surface roughness of the shell gives excellent primary stability, with additional screw fixation as necessary, and the augments are useful when reconstructing larger defects.
The system allows the choice of several bearing options, an important factor when revising younger, more active patients. The short term results have been very encouraging, with excellent clinical and radiological outcomes.
