Hemiarthroplasty for Trapeziometacarpal Arthritis – A Useful Alternative?From the Department of Orthopaedics, The Royal Surrey County Hospital, Guildford, Surrey, UK Correspondence: P. M. Phaltankar, Specialist Registrar, Department of Orthopaedics, Mayday University Hospital, London Road, Thornton Heath, CR7 7YE, UK. Tel.:+44 208 4013000, x 818; Fax:+44 208 4013100; E-mail: p_phaltankar{at}hotmail.com We performed hemiarthroplasty using the Swanson titanium implant for treatment of isolated and advanced trapeziometacarpal joint osteoarthritis Nineteen implants were placed in 18 patients (mean age: 57 years) between 1995 and 1999. One joint required revision and conversion to trapeziectomy. Eighteen joints in 17 patients were evaluated with a mean follow-up period of 34 (range, 14–60) months. Good pain relief was noted in 13 hands. All patients had good hand function as scored using validated questionnaires. Radiographic loosening occurred with five implants and trapezial wear in ten joints. Though radiographic loosening or trapezial wear did not correlate with less satisfactory clinical results, failure of the implant is a concern in the long term. Preliminary results indicate that hemiarthroplasty can be a useful treatment alternative in selected, relatively young patients with isolated trapeziometacarpal osteoarthritis and good bone stock. Good motion and stability can be preserved Failures can be effectively salvaged by trapeziectomy.
