The aim of this study was to investigate the safety of tendoscopy of the peroneus longus (PL) at the sole in a cadaveric model.
Twelve fresh-frozen foot and ankle specimens were used. The locations of the plantar medial and plantar lateral portals were studied. The relationships of the medial and lateral plantar nerves to the tendon sheath of the PL at the sole were also studied.
The plantar lateral portal was located on average 11 mm (6 to 16 mm) proximal and 9 mm (6 to 15 mm) plantar to the fifth metatarsal styloid. The plantar medial portal was located on average 1 mm (12 mm proximal to the joint to 7 mm distal to the joint) proximal to the first tarsometatarsal joint. The lateral plantar nerve touched the PLT sheath in 8 specimens. The nerve was separated from the tendon sheath by a thin layer of muscle in 4 specimens. The medial plantar nerve was separated from the tendon sheath of the PL by the flexor digitorum longus and flexor hallucis longus tendons in all specimens.
Tendoscopy of the PL at the sole of the foot is described; however, the lateral plantar nerve can be at risk and the tendoscopy should be performed with caution.
This cadaveric study provides the anatomic basis of the PL tendoscopy of the sole.
本研究旨在在尸体模型中探究足底腓骨长肌（PL）肌腱镜检查的安全性。
使用12个新鲜冷冻的足踝标本。研究了足底内侧和足底外侧入路的位置。还研究了足底内侧神经和外侧神经与足底PL肌腱鞘的关系。
足底外侧入路平均位于第五跖骨茎突近端11毫米（6至16毫米）和足底9毫米（6至15毫米）处。足底内侧入路平均位于第一跗跖关节近端1毫米（关节近端12毫米至关节远端7毫米）处。8个标本中，足底外侧神经触及PLT腱鞘。4个标本中，神经通过一层薄肌肉与腱鞘分离。在所有标本中，足底内侧神经通过趾长屈肌腱和拇长屈肌腱与PL腱鞘分离。
描述了足底PL肌腱镜检查；然而，足底外侧神经可能有风险，应谨慎进行肌腱镜检查。
本尸体研究为足底PL肌腱镜检查提供了解剖学基础。
