Name the extensor tendons of the ankle.
From medial to lateral, the extensor tendons of the ankle are tibialis anterior, extensor hallucis longus, and extensor digitorum longus.
Name the flexor tendons of the ankle.
From medial to lateral, the flexor tendons of the ankle are tibialis posterior, flexor digitorum longus, and flexor hallucis longus.
What is the origin of the extensor hallucis longus tendon?
This tendon originates from the anterior surface of the middle portion of the fibula and the interosseous membrane.
What is the insertion of the extensor hallucis longus tendon?
This tendon inserts on the dorsal side of the hallux distal phalanx base.
CT was performed after closed reduction and external fixation, with improved alignment of the distal tibial and fibular fractures compared to the initial radiographs. However, there is entrapment of the extensor hallucis longus tendon, which is located completely within the fractured distal tibia. This is best appreciated on the axial and sagittal images with soft tissue windows. There are locules of gas within the distal tibia. An external fixation pin is present in the mid tibial diaphysis.
There is no definite intra-articular extension of the distal tibial fracture. There is no entrapment of the other tendons. Chronic healed fractures of the distal tibial and fibular diaphyses are noted.
