跗管综合征的应用解剖学研究

目的:为跗管综合征的诊治提供形态学基础。方法:对61例成人下肢标本的跗管进行观测。结果:(1)跗管可分为前室、后浅室和后深室,胫神经、胫动静脉位于浅后室内;(2)跗管内容物有3％的变异率;(3)足内外侧神经分叉部59％位于踝跟轴线上方,26％位于下方,9％平轴线;(4)跟神经2支及2支以上者占51.3％。57.8％的跟神经来源于足外侧神经,35.4％来自胫神经,6.8％来自足内侧神经。结论:任何导致后浅室内高压的因素均可引起跗管综合征,手术以松解后浅室为主,各神经支的解剖变异在诊治时应加注意。

Applied anatomy of the tarsal tunnel syndrome

Objective-. Provided the applied anatomic data for the diagnosis and treatment of the tarsal tunnel syndrome. Methods;the structure of the tarsal tunnel were studied on 61 sides of adult cadavers. Results the tarsal tunnel can be divided into anterior space, posterior suerfical sace and posterior deep space, the tibialnerve tibial vessels are located in the posterior superfical space spionts that tibial nerve divids into medial and lateral plantar nerve,59% are above the axion of malleolar-calcanea,26% in the below and 9% on the line (51. 3% calcaneal nerves have 2 or more 2 branchs,57. 8% calcaneal nerves originate from the lateral plantar nerve,35. 5% are from the tibial nerve,6.8% are from the medical plantar nerve. Conclusion; the tarsal syndrome may be caused by any factors which make the pressure of the tarsal tunnel high;it is main to decomress the posterior superfical space in operation.
