To better understand the anatomical variations and pathogeny of tarsal tunnel syndrome, the tibial nerve were dissected in 20 ankles of fresh black African cadavers. The tibial nerve located to 1.75 cm on average from the posterior side of the malleolus and to 2 cm from medial side of the calcaneus tendon. The nerve always ended according to dichotomic method. 90% cases of bifurcation were noted under the flexor retinaculum at 1 cm from the malléolo_calcaneus line; in 10% of dissections, we found proximal bifurcation at 5 cm from this line. The medal calcaneus branch which is a collateral branch of tibial nerve was constant, unique in 80% of cases and double in 20% of cases. The anatomical constatations allow a more precise anesthesia of tibial nerve block. We use constant anatomical marks formed by calcaneus tendon and internal malleolus tip. Olso we more understand the possibility of lesion of tibial nerve at the ankle during the synovites, or ossifications of flexor rétinaculum.
为了更好地理解跗管综合征的解剖变异和发病机制,在20具新鲜的非洲黑人尸体的20个踝关节中对胫神经进行了解剖。胫神经平均位于距内踝后侧1.75厘米处,距跟腱内侧2厘米处。神经总是以二叉的方式终末。90%的分叉情况见于在距踝-跟线1厘米处的屈肌支持带下;在10%的解剖中,我们发现在距该线5厘米处有近端分叉。作为胫神经分支的跟内侧支恒定,80%的病例中为单支,20%的病例中为双支。这些解剖学发现有助于更精确地进行胫神经阻滞麻醉。我们使用由跟腱和内踝尖形成的恒定解剖标志。此外,我们也更清楚了在滑膜炎或屈肌支持带骨化时踝关节处胫神经受损的可能性。
