Arthroscopic first metatarsophalangeal arthrodesis for fixed hallux varus deformity can be very difficult because narrowing of the medial joint space results in difficult access. The abductor hallucis tendon and the medial capsule can be released through a small proximal plantar medial incision. This will convert the deformity into a flexible one and open up the medial joint space. This allows arthroscopic arthrodesis using the standard dorsolateral and medial portals. The plantar medial incision can also be used for arthroscopy of the metatarsosesamoid compartment and insertion of a screw for first metatarsophalangeal arthrodesis.
关节镜下第一跖趾关节融合术治疗固定性拇内翻畸形可能非常困难，因为内侧关节间隙变窄会导致手术入路困难。可通过一个小的足底内侧近端切口松解拇展肌腱和内侧关节囊。这将把畸形转变为可复性畸形，并打开内侧关节间隙。这使得能够使用标准的背外侧和内侧入路进行关节镜下关节融合术。足底内侧切口还可用于跖籽关节间隙的关节镜检查以及第一跖趾关节融合术时螺钉的置入。
