Elektra prosthesis versus resection-suspension arthroplasty for thumb carpometacarpal osteoarthritis: a long-term cohort study
The present study compares 34 patients with thumb carpometacarpal osteoarthritis (37 thumbs) treated with the Elektra® prosthesis, with 18 patients (18 thumbs) treated with resection-suspension arthroplasty, with an overall mean follow-up period of 13.3 years. Evaluation with disability of arm and s...

description | The present study compares 34 patients with thumb carpometacarpal osteoarthritis (37 thumbs) treated with the Elektra® prosthesis, with 18 patients (18 thumbs) treated with resection-suspension arthroplasty, with an overall mean follow-up period of 13.3 years. Evaluation with disability of arm and shoulder scores, pain via visual analogue scale and range of motion (radial and palmar abduction, and opposition) indicated no significant difference. However, the cohort with a surviving prosthesis showed significantly better subjective grip strength (p = 0.04). Complications occurred in 23 of the 37 thumbs in the prosthesis group compared with two in the resection-suspension arthroplasty patients. Seventeen prostheses required revision. At revision operations, we observed local signs of metallosis in 15 of 17 cases. The patients receiving resection-suspension arthroplasty were more satisfied with their treatment (p = 0.003). Therefore, we cannot recommend the implantation of Elektra® prosthesis and we speculate that the key problem of aseptic cup loosening is a result of the metal-on-metal bearing. Level of evidence: III |
