An examination of the operative and post-operative management of trapeziometacarpal osteoarthritis in Ireland

BACKGROUND: The trapeziometacarpal or first carpometacarpal (CMC) joint is the second most common joint affected in osteoarthritis (OA) of the hand. Surgical intervention may be required when conservative measures fail to alleviate symptoms. OBJECTIVE: To investigate operative and post-operative management of trapeziometacarpal osteoarthritis in Ireland. METHODS: An on-line Qualtrics survey was used to determine practice patterns of hand surgeons and therapists including surgical technique, patterns of referral to therapy, treatment protocol and perceived pain impact. RESULTS: Twenty surgeon’s responses were received. Trapeziectomy with Ligament Reconstruction and Tendon Interposition (LRTI) was the most common procedure for all stages of arthritis for sedentary and manual patients. Sixty seven percent (n = 18) stated they perform an additional procedure if stage IV arthritis is present. Eighty percent (n = 16) stated they would perform an additional procedure for MCP joint hyperextension. There were 28 therapist responses. Almost all respondents indicated that patients are initially casted post-surgery with 88% (n = 24) indicating they remain casted for 1-2 weeks. A rigid long thumb spica and neoprene splint are most commonly used. The commencement of exercises differed between respondents and surgical procedures. All participants stated that pain is an issue in the rehabilitation of these patients. CONCLUSIONS: There was consistency in the surgical procedure choice. The stage of arthritis and functional level of the patient was not found to be an important factor for choosing this procedure. There is some consensus for post-operative casting and splinting but more variability in terms of exercise prescription. Pain is a factor to consider post-operatively.
