Checkrein deformity may occur after leg or ankle fractures. It is a dynamic flexion deformity of the big toe after planter flextion of the ankle that disappear when the ankle is dorsiflexed. It is believed to be the result of Tethering or entrapment of the flexor hallucis longus (FHL) tendon in scar tissue or callus at the fracture site,1,2 It was also suggested that it results from contracture of the FHL muscles due to a subclinical or missed compartment syndrome.3 Checkrein deformity is usually noticed during follow up in clinic and it may not respond to conservative management like stretching exercises. Surgical treatment is best done at midfoot by FHL tendon lengthening over lengthening at the fracture site.
