Gould and coworkers (45) further modified the Brostrom procedure by reinforcing the repair using the lateral talocalcaneal ligament
, CFL, and inferior extensor retinaculum, which helped limit inversion and corrected subtalar instability (Fig.
The lateral process of the talus is aided by the lateral talocalcaneal ligament
that extends between it and the calcaneus.
The lateral talocalcaneal ligament originates on the lateral wall of the calcaneus just anterior to the origin of the CFL and inserts onto the body of the talus just inferior to the ATFL.
Finally, the deep layer of the lateral ligamentous complex contains the medial root of the inferior extensor retinaculum, which courses more deeply in the sinus tarsi and sends attachments to both the talus and the calcaneus adjacent to the interosseous talocalcaneal ligament (IOL).
