Young fitness man holding his sports leg injury, muscle painful during training. Asian runner having foot ache and problem after running and exercise outside in summer
Which of the following anatomic structures is most at risk while performing a direct medial approach for a Lapidus bunion correction?
Posterior tibial tendon
The posterior tibial tendon inserts broadly but primarily on the medial navicular. It is well proximal to the site in question
Dorsalis pedis (DP) artery
The DP artery is lateral to the 1st tarsometatarsal joint
Flexor hallucis longus (FHL)
The FHL is relatively plantar as compared to this medial approach
Anterior tibial tendon
The anterior tibial tendon inserts dorsomedially on the medial cuneiform and the 1st metatarsal base (the bones involved in a a Lapidus procedure). It is at risk with a direct medial approach
Dorsal medial hallucal cutaneous nerve
The dorsal hallucal cutaneous nerve is at risk, but the risk is greater to the anterior tibial tendon with a direct medial approach to the 1st tarsometatarsal joint
