An intramedullary cement spacer in total hip arthroplasty

Revision arthroplasty of the hip is often complicated by infection, bone loss, and perioperative fracture of the femur. A simple, inexpensive spacer that keeps tissue planes intact and prevents soft tissue contracture during the interoperative period of a 2-stage revision is described. This can provide intramedullary support to a fractured or weak femur and enable local antibiotic delivery, as well as permit limited mobilization of the patient. It can be easily fabricated during surgery using universally available materials and can be tailored for specific requirements. Such a spacer was used in 5 cases. The experience is presented, and the technique and pitfalls are discussed.
