Reconstruction options and outcomes for acetabular bone loss in revision hip arthroplasty

Abstract: Revision total hip arthroplasty in the setting of acetabular bone loss is a challenging procedure and requires a solid understanding of current acetabular reconstruction options. Despite major developments in the field of revision hip surgery in recent decades, reconstruction of acetabular defects remains a major problem in order to achieve primary stability and durable fixation without sacrificing additional bone stock. Although there are several ways to classify acetabular bone defects, the Paprosky classifi… Show more

“…Once initiated, the processes of the immune response lead to the loosening and migration of the implant, destruction of the bone tissue around it, and ultimately to worsening discomfort, pain and gait failure of the patient [4,5]. Acetabular and femoral defects are classified according to the commonly accepted Paprosky classification and vary from the minor (type I) to extensive destruction (types III and IV) [6,7,8,9].…”

“…Reduced bone stock can be associated with septic and aseptic failure, periprosthetic fracture, osteoporotic fracture in the elderly with severe comminution or failed fracture fixation, and multiple revisions [ 2 7 ]. In case of severe proximal femoral bone loss multiple treatment options have been described in the literature, including structural allograft-prosthesis composite, impaction allografting, long revision stems, resection arthroplasty, and proximal femoral replacement (PFR) [ 3 , 4 , 8 ]. Proximal femoral replacement, also known as “megaprosthesis”, is a well-established limb salvage procedure for reconstruction of bone defects after the oncological resections of malignant bone neoplasms [ 9 ] and the encouraging outcomes have broadened the indications to the treatment of severe bone loss in non-oncologic conditions [ 10 , 11 ].…”

“…Different procedures such as mobile components exchange, partial reimplantation of a cup or stem, and the most di cult cases of total prosthesis reimplantation are performed during the RHA. An extended surgical approach, soft tissue damage and bone defects, longer time of surgery, and the need to use more complex implants for acetabulum or modular stems are the main features of RHA that in uence on higher complication rate including perioperative blood loss [3,4,5].…”
