目的 :为临床治疗垂状指及屈肌腱止点重建的新方法提供解剖学依据。方法 :对 2 0具 40侧成人尸体的跟骨 -跖肌腱、第 1掌骨—拇长展肌、第 2掌骨—桡侧腕长伸肌可行供区 ,进行止点类型、附着点面积、可切取骨块情况、以及相邻解剖结构和解剖变异等方面进行解剖学研究。并用SPSS统计软件进行统计和分析。结果。① 90 %的跖肌腱直接附着于跟骨而不与跟腱融合 (集中型占 85% ) ,止点面积为 ( 6 9.5± 4.4)mm2 ;② 93%拇长展肌腱直接附着于第 1掌骨基底部桡侧 (集中型占 87% ) ,止点面积为 ( 2 7.9± 3.4)mm2 ;③ 90 %桡侧腕长伸肌腱直接附着于第 2掌骨背侧或大于 1 /2桡背侧 (集中型占 90 % ) ,止点面积为( 31 .6± 4.2 )mm2 。切取骨块形状分为椭圆形 (平均占 1 2 % )、横形 (平均占 8% )、圆形 (平均占 7% )、弥散形(平均占 1 3% )。结论 :①跟骨—跖肌腱、部分第 1掌骨—桡侧腕长伸肌和第 2掌骨—拇长展肌的肌腱附着点形状、面积、可切取的骨块都能满足骨—肌腱移植的要求 ;②切取 3个骨—肌腱供区对手足功能无任何影响 ,为临床构制骨—肌腱移植提供了解剖学依据。
OBJECTIVE: To provide anatomical basis for a new clinical approach to the treatment of dorsal digit and flexor tendon. Methods: Twenty (40) adult cadavers - plantar tendons, the first metacarpal - extensor digitorum longus and the second metacarpal - Cut the bone, as well as the adjacent anatomical structures and anatomical variations in anatomical studies. And use SPSS statistical software for statistics and analysis. result. 90% of the plantar tendon attached directly to the calcaneus rather than with the Achilles tendon fusion (85% of the concentrated type), the stop area of (6 9.5 ± 4.4) mm2; ② 93% of the thumb long extensor tendon attached directly to the first metacarpal The radius of the basal portion was 87%, and the area of the stop was (7.9 ± 3.4) mm2. ③ The tendon of 90% radial wrist was directly attached to the dorsal side of the second metacarpal or more than 1/2 of the dorsal radial Concentrated accounted for 90%), deadline area (31.6 ± 4.2) mm2. Cut the shape of the bone into oval (average 12%), horizontal (average 8%), round (average 7%), diffuse (average 13%). CONCLUSIONS: ① The shape, area and incision of the tendon of the calcaneal-plantar tendon, part of the first metacarpal-radial extensor cuff and the second metacarpal-extensor digitorum longus muscle can all satisfy the bone-tendon graft Requirements; â’¡ cut off three bone - tendon for the hand and foot functions without any impact on the anatomical basis for the clinical structure of bone - tendon transplantation.
