In conclusion, use of a sinus tarsi
rotational flap for an open lateral malleolus wound is a simple, effective, and rapid-healing approach for treatment of small to moderate sized wounds ([less than or equal to] 5 cm), other than ulcerous wounds.
The head and neck regions are richly supplied by the superior neck vessels and the artery of the sinus tarsi and osteonecrosis of these areas is extremely rare whereas lateral 1/2 of the talar body is vulnerable because of its precarious blood supply and degree of displacement of the body, osteonecrosis rates can be 100%.
The artery of the sinus tarsi, formed by the branches of perforating peroneal artery, the dorsalis paedis (or anterior tibial) artery, or anastomoses between the two and supplies the lateral 1/8 to % of talar body.
A tarsal coalition Residual pain in the sinus tarsi
after the original sprain heals can also be due to an unrecognized tarsal coalition.
Bony changes seen with subtalar instability and inflammatory arthropathies are discussed with sinus tarsi
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).
