Background: Total elbow prostheses are broadly classified into linked and the unlinked categories. We have looked at long-term results of unlinked Kudo 5 total elbow replacement used in the treatment of patients with rheumatoid arthritis in 2 hospitals.

Methods: 87 Kudo 5 Total elbow replacements in 70 patients with adult rheumatoid arthritis were performed at Wexham Park Hospital, Slough and City Hospital, Nottingham by 2 specialist elbow surgeons, the senior authors. 16 patients had died and 8 patients were lost to follow up. 62 elbow replacements in 46 patients were evaluated at a mean follow up of 79 months [29–137 months] using the Mayo Clinic Performance Index. Postoperative radiographs were also reviewed for loosening using standard anteroposterior and lateral films

Results: Preoperatively 6 had moderate pain and 56 had severe pain. Postoperatively the pain was rated as none or mild by 58 and moderate by 4. The average Mayo Elbow Score improved from 37 preoperatively to 86 postoperatively. The mean arc of flexion/extension improved from 60 to 99 degrees. There were 14 complications including ulnar neuropraxia, fracture, dislocation, triceps rupture and loosening. 4 cases were revised, 2 for aseptic and 2 for septic loosening. Postoperative radiographs showed 5 cases with loosening around the ulna component.

Conclusions: The long-term results using the Kudo 5 elbow prosthesis in patients with rheumatoid arthritis are acceptable and comparable to other series reported of this implant. To date this is the largest series reported with the longest follow up using this implant.

To date there has been only one published series of elbow arthroplasty in patients with Juvenile Idiopathic arthritis. These patients pose particular problems because of the size and variable shape of the humerus and ulna together with the soft tissue contractures and bony erosion which can sometimes be severe. We have reviewed the results of elbow arthroplasty using the unlinked Kudo 5 and the linked Coonrad-Morrey implants which in our practice have different indications dependent upon bone stock and stability.

Methods 19 total elbow replacements in 13 patients with juvenile idiopathic arthritis were performed by 1 specialist elbow surgeon, the senior author. 13 of these are Kudo 5 and 6 are Coonrad-Morrey implants. The mean age at operation was 39 years. 6 of the elbow replacements had undergone previous surgery, 4 had an interposition arthroplasty and 2 a synovectomy and radial head excision. No patients were lost to follow up. All were evaluated at a mean follow up of 49 months [6–84 months] using the Mayo Clinic Performance Index. Postoperative radiographs were also reviewed for loosening using standard anteroposterior and lateral films.

Results Preoperatively 7 had moderate pain and 12 had severe pain. Postoperatively the pain was rated as none by 13 and mild by 6. The average Mayo Elbow Score improved from 26 preoperatively to 81 postoperatively. The mean arc of flexion/extension improved from 85 to 108 degrees.12 elbow replacements had intra and post-operative complications and 2 elbows have been revised.

Conclusions The medium-term results of Total Elbow Replacements in patients with Juvenile Chronic Arthritis are acceptable and comparable to the only other published series which also records a high complication rate.
