EARLY RESULTS OF THE ACCLAIM TOTAL ELBOW ARTHROPLASTY

Wrightington Hospital, Hall Lane, Appley Bridge, Wigan, Lancashire WN6 9EP, UK

We present the early results of 36 primary total elbow arthroplasties using the Acclaim prosthesis. The Acclaim prosthesis was used in 46 primary total elbow arthroplasties between July 2000 and August 2002. All operations were performed or directly supervised by the two senior authors (IAT and JKS). There were 32 females and 14 males. The mean age at surgery was 64 years (range, 34–93). The underlying pathology was rheumatoid arthritis in 39, osteoarthritis in five and post-traumatic arthritis in two. The early results of 36 cases are presented at a minimum follow-up of two years. Patients were assessed using the American Shoulder and Elbow Surgeons patient self assessment form and the range of movement of the elbow measured. The Wrightington method was used for radiographic analysis of lucencies. There was good relief of pain and range of movement improved. The mean preoperative pain score was 8.1 and decreased to 2.1 at latest follow up. The mean disability score increased from 34.2 to 66.1. The mean overall satisfaction rating following surgery was 9.3 on a visual analogue scale from zero to ten. The mean range of flexion increased from 83^oto105^o. The mean flexion gain was just over 10^o and the mean extension gain was just over 12^o. There were 11 cases of intraoperative fracture of the humeral condyle. One of these fractures failed to unite and required revision to a linked prosthesis because of persistent instability. There was one case of deep infection. There were three cases of ulnar neuropathy, one of which resolved. There was no evidence of loosening. The Acclaim total elbow arthroplasty gives good symptomatic relief and improvement in function according to the American Shoulder and Elbow Surgeons patient self assessment form. These early results are encouraging but the frequency of intra-operative fractures is of some concern.
