Retrospective case series.
When conservative modalities and therapies fail to control symptoms of thumb carpometacarpal (CMC) joint osteoarthritis, surgery may be indicated.
To present a rehabilitation protocol used in a series of patient cases after suspension arthroplasty and to evaluate outcomes.
Twenty-seven patients with CMC osteoarthritis were treated by the same arthroplasty technique and the same rehabilitation program. Patients were evaluated before and 12th week after surgery, and at the last follow-up using a visual analog scale; the Disability of the Arm, Shoulder, and Hand questionnaire; strength measurements; range of motion evaluations; and radiographic assessment.
Average follow-up period was 31.5 months. There was a decreasing trend in both subjective scores during follow-ups (p=0.0001). Thirty-three percent and 30% improvements on radial and palmar abductions, respectively, and 29% improvement on pinch strengths were recorded at the final follow-up. Postoperative grip improvement was not preserved at the last follow-up.
Level 4.
The results demonstrate a high degree of patient satisfaction suggesting the efficacy of this surgical technique and postoperative rehabilitation protocol.
