What does the extensor retinaculum of foot do?
What does the extensor retinaculum of foot do?
The superior extensor retinaculum is located proximally to the dorsal aspect of the ankle joint and houses the tibialis anterior, extensor digitorum longus, extensor hallucis longus, and fibularis tertius tendons.
Can you sprain the retinaculum?
Extensor Retinaculum Peroneal retinacula are often injured during ankle sprains (inversion injury).
What passes behind the extensor retinaculum?
Four tendons, a nerve and an artery pass under the extensor retinaculum.
How do you treat flexor retinaculum?
Treatment: Rest, icing, and, compression socks to bring down swelling are generally the top recommended treatments for a strained flexor retinaculum.
Can retinaculum repair itself?
Superior peroneal retinaculum tears are often mistaken for lateral ankle instability. These tears often do not heal readily by themselves and must be identified so that proper treatment can begin.
Where does the extensor retinaculum attach?
the radius
The extensor retinaculum is attached laterally to the lateral margin of the radius. However, it is not attached to the ulna medially, as the distance between these two bones varies with supination and pronation of the forearm.
How long does it take for the retinaculum to heal?
Recovery from surgery requires a moderately long period, usually in the order of 2-6 weeks of immobilization, in order to allow the retinaculum and any bony procedures to heal. This is followed by four to six weeks of fairly graduated and intensive rehabilitation.
Can you injure the flexor retinaculum?
Injury to the medial flexor retinaculum can contribute to medial subluxation of the tibialis posterior tendon, but injury to the tendon fibro-osseous tunnel is usually also required for frank dislocation to occur [6].
What is the most medial structure passing under the inferior extensor retinaculum of the foot?
Tibialis anterior tendon
Tibialis anterior tendon (arrowheads) is most medially located and passes though tunnels formed by oblique superomedial limb (short arrows) and oblique inferomedial limb (long arrows) of inferior extensor retinaculum.
How to treat pain in the inferior extensor retinaculum?
Complete immobilization of the affected foot is necessary for which the physician may recommend casting as well. Use of NSAIDs is recommended to control swelling, pain, and inflammation associated with Inferior Extensor Retinaculum Pain or Strain. In very rare cases, surgery is required to treat an injured Inferior Extensor Retinaculum.
Where is the retinaculum located in the foot?
It originates at the anterior aspect of the distal fibula and attaches medially to the anterior aspect of the distal tibia 1. The inferior extensor retinaculum is Y shaped and is located distal to the superior extensor retinaculum at the dorsal aspect of the foot. The stem of the retinaculum is located at the upper surface of the calcaneus.
Why is the inferior extensor retinaculum considered a double layer?
The inferior extensor retinaculum is considered a double layer due to one lamina (thin sheet) passing behind and the other passing in front of the tendons of the extensor digitorum longus and the peroneus tertius. The extensor digitorum longus muscle is located on the lateral (side) portion of the front part of the leg.
Where does the sixth compartment of the retinaculum originate?
Each septum originates from the supratendinous retinaculum and inserts onto the radius. The sixth compartment for the extensor carpi ulnaris is complex.
