Abstract
Abstract
Purpose
To evaluate the objective and subjective long-term clinical outcomes of tendon transfer and tendon graft for extensor tendon ruptures in rheumatoid hands.
Methods
We evaluated the long-term clinical outcomes of tendon transfer and tendon graft for extensor tendon ruptures in rheumatoid hands of 37 patients (43 hands) followed up for a mean of 14 years (range, 10–21 years).
Results
The mean time from rupture to surgery was 13.1 weeks (range, 3–48 weeks). The mean extension lag of the metacarpophalangeal joint was 8.7° (range, 0–40°), the mean pulp-to-palm distance was 0.4 cm (range, 0–3 cm), and the mean overall satisfaction rate was 86.5 (range, 70–100). There were no significant differences in clinical outcomes between tendon transfers and tendon grafts. There was a significant correlation between extension lag of the metacarpophalangeal joint and overall satisfaction rate (R2 = 0.155; p = 0.009). Time to surgery was significantly correlated with extension lag of the metacarpophalangeal joint (R2 = 0.437; p = 0.001) in the tendon graft group.
Conclusions
Both tendon transfer and tendon graft for extensor tendon ruptures in rheumatoid hands achieve satisfactory results that are maintained for an average of 14 years. In cases of tendon graft, the time to surgery should be considered, and there is concern over extension lag of MP joint.
