A simple technique has been used to correct the clawing of fingers in patients with Hansen's disease. The distal part of the palmar plate is excised and the remaining portion is advanced and sutured with a single horizontal mattress suture to prevent hyperextension of the metacarpophalangeal joint. A pulley advancement is also done. One hundred five claw hands were corrected in 99 patients from December 1985 to September 1988. Follow-up period varied from 6 months to 3 1/2 years. The results were assessed for correction of deformity, power grip, motion, and function. Out of 94 hands that were followed up after operation, power grip remained static in most cases. Correction of deformity was satisfactory in 85 hands, motion and function of the fingers were satisfactory in 63 hands, and correction of the clawing was statistically significant in two fingers (p less than 0.01).
一种简单的技术已被用于矫正麻风病患者手指的爪形畸形。切除掌板的远端部分，将剩余部分推进并用单水平褥式缝线缝合，以防止掌指关节过度伸展。同时也进行滑车推进术。1985年12月至1988年9月期间，对99例患者的105只爪形手进行了矫正。随访时间从6个月至3年半不等。对畸形矫正、强力握力、活动度和功能进行了评估。在术后接受随访的94只手中，大多数情况下强力握力保持稳定。85只手的畸形矫正效果令人满意，63只手的手指活动度和功能令人满意，两个手指的爪形畸形矫正具有统计学意义（p<0.01）。
