Objective. This retrospective study was designed to evaluate the outcomes of four different surgical reconstructions for extensor tendon ruptures in ulnar three fingers in 48 patients with rheumatoid arthritis. Methods. The following four techniques were performed; palmaris longus tendon grafting (PL group; n = 9), extensor indicis proprius (EIP) tendon transfers (EIP group; n = 8), end-to-side transfers with tension-reduced early mobilization (End-to-side group; n = 16), and a combination of end-to-side and EIP transfers (Combination group; n = 15). Loss of extension was evaluated to determine the mean postoperative range of motion of the metacarpophalangeal (MP) joint and clinical outcomes were categorized using modified Geldmacher criteria. Results. Combination group demonstrated the best mean MP joint extension (- 3°), followed by End-to-side group (- 12°), EIP group (- 16°), and PL group (- 21°). Combination group yielded the best clinical outcomes with all cases showing good results. Conclusions. The combination of end-to-side and EIP transfer was an effective surgical reconstruction procedure for triple fingers extension loss.
