Few studies have reported about isolated contracture in the extensor hallucis longus (EHL) muscle, but none of the EHL muscle contracture after distal tibial physeal injury. Two such cases in 16- and 14-year-old boys who underwent surgeries for distal physeal injury of the tibia at a previous hospital are presented. Extension contracture of the hallux appeared 1-2 months post-surgery. Physical examinations revealed that the extension contracture of the first metatarsophalangeal joint was aggravated in plantar flexion of the ankle due to a tenodesis effect, and magnetic resonance imaging showed atrophy and signal changes in the anterior compartment muscles. This was diagnosed as EHL muscle contracture due to anterior compartment syndrome (ACS) after distal tibial physeal injury. The EHL tendon transfers were performed in both cases, with favorable short-term results. Therefore, the EHL tendon transfer might be preferable in case of the EHL muscle contracture due to partial ACS.
