The course of the flexor hallucis tendon (FHL) is divided into three zones. Zone 1 is located behind the ankle joint, from the musculotendinous junction to the orifice of the tunnel underneath the sustentaculum tali. Zone 2 is located from the tunnel underneath the sustentaculum tali to the knot of Henry. Zone 3 is located from the knot of Henry to the tendon insertion to the base of the distal phalanx of the big toe. The zone 1 FHL tendon is examined with posterior ankle endoscopy with the posterolateral and posteromedial portals. The zone 2 FHL tendon can be examined through the posteromedial and the plantar portals. The zone 3 FHL tendon is examined with the toe flexor tendoscopy. By means of different endoscopic approach to the each zone of the FHL tendon, the complete course of the tendon can be examined from the musclotendinous junction to its insertion.
拇长屈肌腱（FHL）的走行分为三个区域。区域1位于踝关节后方，从肌腱结合部至载距突下方隧道的开口处。区域2位于载距突下方的隧道至亨利结之间。区域3位于亨利结至肌腱在拇趾远节趾骨基部的附着点之间。区域1的FHL肌腱通过后外侧和后内侧入路的后踝关节镜进行检查。区域2的FHL肌腱可通过后内侧和足底入路进行检查。区域3的FHL肌腱通过趾屈肌腱镜进行检查。通过对FHL肌腱各区域采用不同的内镜入路，可从肌腱结合部至其附着点检查肌腱的完整走行。
