Hindfoot endoscopy for accessory flexor digitorum longus and XXXX @entity2762 .

@entity1 @entity1795 @entity158 @entity850 @entity2762
We present a case report involving the flexor digitorum accessorius longus (FDAL) tendon which travels through a fibro-osseous tunnel together with the @entity1795 ( @entity1795 ) tendon, causing a stenosing @entity2762 . The @entity1 was admitted with posteromedial ankle @entity158 and diagnosed clinically as @entity2762 . We found two tendons in the tunnel during hindfoot endoscopy. The @entity850 was relieved by endoscopic debridement. After the operation, we checked the MRI images and observed two tendons. We concluded that the accessory tendon was the FDAL. Two years later the @entity1 was admitted with the same symptoms. We excised the FDAL muscle and the @entity1 's symptoms resolved. The FDAL muscle is a cause of @entity2762 . Because of its variability and mostly asymptomatic nature, it may not be noticed it on an MRI scan. Hindfoot endoscopy is a safe tool for the diagnosis of this condition and curative treatment is afforded by excision of the FDAL muscle.
