Isolated third-toe transfer is a versatile and safe technique when indicated.
Between January of 1984 and January of 2003, 37 isolated third-toe transfers were performed in 31 patients.
Only one partial loss was noted among 37 transfers. There were 24 male and seven female patients, with an average age of 27.4 years (range, 7 to 43 years). Twenty-five patients received additional toe transfers. Secondary surgery was performed in 17 toes of 15 patients to improve the functional and cosmetic results. Patients were followed for 2 to 180 months (average, 36 months) and no significant donor-site morbidity was seen.
Basically, the indications for isolated third-toe transfer are evaluated in two groups. Third-toe transfer is absolutely indicated when it is necessary for restoring basic hand functions in multiple-finger amputations. It is indicated because both second toes are transferred or the remaining second toe is adjacent to the previously transferred great toe. The other absolute indication is the unavailability of second toes because of trauma or deformity. Third-toe transfer is indicated relatively if it is used for additional reconstruction when basic hand functions are regained or already exist. Another relative indication is its better size match for proposed reconstruction. Second and third dorsal and plantar metatarsal arteries can be used as the pedicle artery for third toe-transfer; however, if second-toe transfer has already been performed or is planned, the third plantar or dorsal metatarsal artery should be used. Isolated third-toe transfer is a useful and reliable technique, especially in multiple-finger amputation reconstruction.
在有指征时,孤立的第三趾移植是一种通用且安全的技术。
1984年1月至2003年1月期间,对31例患者进行了37例孤立的第三趾移植。
37例移植中仅1例出现部分缺失。患者中男性24例,女性7例,平均年龄27.4岁(范围7至43岁)。25例患者接受了额外的趾移植。对15例患者的17个趾进行了二次手术以改善功能和外观效果。对患者随访2至180个月(平均36个月),未发现供区有明显并发症。
基本上,孤立第三趾移植的指征分为两组评估。当多指截肢后恢复基本手部功能有必要时,绝对指征为第三趾移植。其指征为双第二趾均已移植或剩余第二趾与先前移植的拇趾相邻。另一个绝对指征是因创伤或畸形无法获取第二趾。当基本手部功能已恢复或原本就存在,用于额外重建时,相对指征为第三趾移植。另一个相对指征是其与拟行重建的尺寸匹配更佳。第二和第三跖背动脉及跖底动脉均可作为第三趾移植的蒂动脉;然而,如果已经进行或计划进行第二趾移植,则应使用第三跖底或跖背动脉。孤立第三趾移植是一种有用且可靠的技术,尤其在多指截肢重建中。
