Total Hip Replacements in Patients with Rare Pathologic Conditions Affecting Bone

As a result of the advances in surgical technique and implant design, total hip arthroplasty (THA) is increasingly offered for the management of osteoarthritis of the hip in patients with fragile or pathologic bone.

Posttraumatic or congenital deformities associated with fragile or pathologic bone are frequently encountered and necessitate diligent preoperative planning.

Surgeons should be prepared to evaluate and manage intraoperative iatrogenic fracture.

While there is limited evidence to date, components made with computer-assisted design can be considered, given the unique and highly variable patient population.
