While not as prevalent as arthroplasty of the shoulder,knee,or hip,total elbow replacement is indicated for patients with traumatic lesions or excessive bone loss from rheumatic or degenerative arthritis,resulting in elbow instability and pain or bilateral elbow ankylosis.The prosthesis may be used with or without PMMA,depending on the quality of the diseased bone and the design of the implant.If PMMA is not used,what replacement product,element,or substance is used?

Question

If PMMA is not employed,bone grafting with local bone that has been resected may be used to help seat the ulnar component snugly and achieve adequate bony contact against the porous coating of the metal ulnar component.The design of implants and methods of fixation for postoperative stability have presented challenges that have been overcome in arthroplasty of other joints but remain a challenge in elbow arthroplasty.Postoperative stability of the elbow implant depends largely on the soft tissues surrounding the joint.Patients with degenerative arthritis generally have better results from elbow arthroplasty than those undergoing this procedure after injury to the elbow joint.
