  • Total elbow arthroplasty is still in its infancy compared with other arthroplasties, such as knee or hip arthroplasties. Implant design has been evolving with clinical experiences; however, there are only limited data on the long-term clinical outcome of elbow arthroplasty in the literature. The design of total elbow prostheses can be divided into three categories: linked (constrained or semi-constrained), unlinked (unconstrained), and convertible types. The choice between an unlinked (unconstrained) implant and a linked (semi-constrained) implant depends on joint stability and adequacy of the bone stock. Linked elbow arthroplasty has provided high patient satisfaction, and pain relief thanks to proper patient selection, advancement of implant design, improvement in cement techniques, meticulous surgical technique, and appropriate postoperative rehabilitation. Concerns remain about the use of this implant in young or high-demand patients. This article focuses on the linked (semi-constrained) prostheses, which provides an overview of the current state of linked total elbow arthroplasty.

  • Purpose: The current study reports the clinical results of total elbow arthroplasties (TEA) which were Performed on patients with poor clinical and radiological results after initial surgeries for elbow fractures or dislocations. Materials and Methods: The clinical outcomes of twelve consecutive patients who underwent TEA after failed surgeries for elbow fractures or dislocations from january, 1995 to December, 2005 were evaluated. The initial diagnoses were distal humeral fractures in 8 cases and fracture-dislocations in 4 cases. The Mean period from the initial operations to the TEAs was 12 months. The mean folloow up period after TEA was 43 months. Results: The mean range of motion, in terms of active extension, activeflexion, supination, and pronation, improved from $14.2^{\circ}$, $96.7^{\circ}$, $50.8^{\circ}$ and $53.3^{\circ}$ to $5.4^{\circ}$, $122.1^{\circ}$, $63.3^{\circ}$ and $67.5^{\circ}$, respectively (p<0.05). RAdiolucent lines were found in 3 cases, which were 1 case of type 3, and 2 cases of type 4. All three loosening cases underwent revision TEAs. The mean postoperative Mayo elvow performance score was 79 point. There were 6 cases of excellent, 2 cases of good, and 4 cases in poor. Conclusion: Good clinical results were obtained after TEA performed in failed surgeries for elbow fractures of dislocations.

  • Purpose: Total elbow arthroplasty (TEA) is still in its infancy as compared with other forms of arthroplasty. TEA designs have evolved with experience, but comparatively little long-term outcome data is available. This article provides an overview of the current states of linked, unlinked, and convertible total elbow arthroplasty. Material and Method: The designs of total elbow prostheses can be subdivided into three categories: unlinked, linked, and convertible. This article provides an overview of the current states of linked, unlinked, and convertible total elbow arthroplasty. Results and Conclusion: By proper patient selection and by utilizing implant design advances, improvements in cementation techniques, a meticulous surgical technique, and appropriate postoperative rehabilitation, total elbow arthroplasty can provide a high level of patient satisfaction and pain relief.
