Long-term follow-up of trapeziometacarpal arthroplasty with coexisting scaphotrapezial disease.
Visualization of the scaphotrapezial joint during basal joint arthroplasty has been recommended to establish the stage of degeneration. This study attempts to clarify that recommendation and evaluate whether moderate wear of the joint precludes a good result of trapeziometacarpal hemiarthroplasty. To assess the need for inspection of the scaphotrapezial joint, x-ray films, tomograms, and operative findings in 23 cases of basal joint arthroplasty were reviewed. X-ray findings agreed with operative findings at the scaphotrapezial joint in only 76% of the cases. We also evaluated 18 thumbs in 15 patients who underwent interposition arthroplasty of the trapeziometacarpal joint and at surgery had moderate degenerative changes of the scaphotrapezial joint. The scaphotrapezial joints were left intact and the trapeziometacarpal joints were reconstructed. Follow-up averaged 8 years. In no case was there x-ray or symptomatic progression of the disease at the scaphotrapezial joint. Clinically, 78% were rated excellent, 17% good, and 5% fair.
