title: Outcome analysis of trapezectomy with and without pyrocarbon interposition to treat primary arthrosis of the trapeziometacarpal joint.
abstract: We performed a prospective cohort comparative analysis of simple trapezectomy and trapezectomy with pyrocarbon interposition in 38 consecutive patients with trapeziometacarpal joint osteoarthrosis. Patients were assessed preoperatively, at six and 12 months postoperatively using subjective and objective tools. Subjective assessment was performed using the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire and the visual analogue score. Objective assessment was performed with grip strength measurements. At each time interval, statistical differences were sought between the two subgroups. No significant difference between the two subgroups was noted at any time interval on subjective or objective assessment. A significant difference (p < 0.05) was found on comparing the respective preoperative and 12-month subjective scores in both subgroups. Of the pyrocarbon subgroup seven had related complications. We suggest that pyrocarbon interposition does not significantly improve postoperative function, requires a longer operation with a high postoperative risk of pyrocarbon displacement and need for revision surgery.
