Main Implants Available for Replacement of the Elbow Joint

The field of elbow arthroplasty continues to experience substantial improvements. Currently, elbow replacement represents a successful treatment alternative for patients with inflammatory conditions as well as selected patients with posttraumatic osteoarthritis, elderly patients with low, comminuted distal humerus fractures, the salvage of distal humerus nonunion, ankylosis, haemophilic arthropathy, and elbow reconstruction after tumor resection. Some linked arthroplasty designs seem to be associated with a better outcome and allow the management of a wider range of pathology. There is interest in the development of improved designs which will decrease the rate of polyethylene were and mechanical failure in higher demand patients and provide increased flexibility in the primary and revision setting. The role of distal humerus hemiarthroplasty, linkable implants and components for the radial head need further investigation.

Schneeberger . [] published the results of a study of 41 patients with posttraumatic osteoarthritis using the Coonrad-Morrey prosthesis. The mean age of the patients at the time of surgery was 57 years (range, 32 to 82 years) and the mean follow-up time was five years. Seventy-three per cent of the patients had no or mild pain and the results were considered satisfactory in 83 per cent of the cases. However, there was a 27 per cent complication rate, including five ulnar component fractures and two revisions for polyethylene wear. These authors concluded that elbow arthroplasty should be relatively contraindicated in patients planning to perform substantial physical activities with the involved upper extremity or are not able to comply with the previously mentioned postoperative restrictions.

Total elbow replacement is a very effective treatment in the correct patient

When reporting Z47.1 (aftercare following joint replacement surgery), coders should note instructions to use an additional code to identify the joint from Z96.6-.

Total elbow arthroplasty has continued to evolve over time. Elbow implants may be linked or unlinked. Unlinked implants are attractive for patients with relatively well preserved bone stock and ligaments, but many favor linked implants, since they prevent instability and allow replacement for a wider spectrum of indications. Inflammatory arthropathies such as rheumatoid arthritis represent the classic indication for elbow arthroplasty. Indications have been expanded to include posttraumatic osteoarthritis, acute distal humerus fractures, distal humerus nonunions and reconstruction after tumor resection. Elbow arthroplasty is very successful in terms of pain relief, motion and function. However, its complication rate remains higher than arthroplasty of other joints. The overall success rate is best for patients with inflammatory arthritis and elderly patients with acute distal humerus fractures, worse for patients with posttraumatic osteoarthritis. The most common complications of elbow arthroplasty include infection, loosening, wear, triceps weakness and ulnar neuropathy. When revision surgery becomes necessary, bone augmentation techniques provide a reasonable outcome.

The surgical and therapeutic management for total elbow arthroplasty is reviewed

AB - Thirty capitellocondylar unhinged implant arthroplasties were performed on 27 patients during the period from October 1976 through June 1981. The average patient age was 59.4 years, with a preoperative diagnosis of rheumatoid arthritis in 28 elbows and osteoarthritis in two elbows. Follow-up periods averaged 39.9 months (range, 10-62 months). The indications for elbow arthroplasty were intractable pain, joint instability, failed synovectomy, or bilateral limitation of motion. Range of motion evaluations showed moderate increases in flexion, pronation, and supination after operation, although there was no significant improvement in extension. Ewald functional evaluation scores improved significantly from a mean of eight points prior to operation to a postoperative mean of 85 points. The significant complications occurring were deep wound infections, necessitating removal of the prosthesis (6.6%), and subluxation (13.2%), which responded to conservative treatment by long-arm casting. One patient required reconstruction of the medial collateral ligament for subluxation. Ulnar nerve paresthesia developed in 10% of the patients. One patient required neurolysis and transposition of the nerve for relief of symptoms. The posterolateral approach was adopted to reduce the incidence of ulnar nerve complications.

The indications for total elbow arthroplasty include ..

Deep periprosthetic infection affects the elbow more commonly than other joints. This is attributed to the thin soft-tissue envelope of the elbow as well as the higher risk of infection in patients with relative immune suppression secondary to inflammatory conditions or failed previous surgical procedures for trauma. Currently, the incidence of infection after elbow arthroplasty is estimated to be between 2 and 4 per cent [,] Antibiotic-loaded polymethylmethacrylate is used routinely for implant fixation in an effort to decrease the rate of infection. Acute infections may be treated with irrigation, debridement, polyethylene exchange and retention of the components. Chronic infections may be treated with two-stage reimplantation or resection depending on the nature of the infection, patient needs and remaining bone and soft-tissues.

Total Elbow Arthroplasty: Surgical Technique - …

There are different philosophies for the use of elbow arthroplasty in distal humerus fractures. The author’s preferred strategy is to work through a bilaterotricipital approach, resect the fractured fragments, and complete the arthroplasty. When the distal fragments are resected, the collateral ligament complexes and the flexor-pronator and extensor-supinator groups are detached. A linked arthroplasty is needed to compensate for the ligamentous insufficiency. The forearm muscular groups are sutured to the triceps to seal the joint; interestingly, resection of the humeral condyles does not seem to affect grip strength or strength in flexion, extension, pronation or supination []. Other philosophy consists in fixing the condyles to preserve the integrity of the collateral ligaments and replace the articular surface with a distal humerus hemiarthroplasty or a total elbow replacement.

Total Elbow Arthroplasty Protocol.

The relatively high mechanical failure rate of elbow arthroplasty in patients with posttraumatic osteoarthritis has been the main driving force for the development of newer implants with supposedly better wear patterns. There are no published studies on the outcome of these new designs. An alternative strategy in younger patients is to offer them an interposition arthroplasty as their first procedure as long as they understand that pain relief is not reliable; fortunately, the outcome of replacement after failed interposition arthroplasty is equivalent to that of patients without previous interposition [].
