Can you sprain a retinaculum?
Peroneal retinacula are often injured during ankle sprains (inversion injury). Anytime there is persistent pain after an ankle sprain, a retinaculum injury should be considered. For more information on ankle sprains read my six part blog on Ankle Sprains (Inversion Sprain).
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.
Can you sprain inferior extensor Retinaculum?
Extensor retinaculum injury is uncommon, and can be traumatic or postsurgical. Disruption of the retinaculum can result in bowstringing or dislocation of the extensor tendons. Sprain of the retinaculum can result in pain and fibrosis around the retinaculum.
Can you tear your superior peroneal retinaculum?
Injury of the superior peroneal retinaculum (SPR) occurs with peroneal dislocation through forceful ankle dorsiflexion and concomitant reflex peroneal muscle contraction. This injury has been described in conjunction with numerous sports activities, particularly snow skiing.
What happens if you tear your retinaculum?
When functioning correctly, tendons glide under these retinacula without hindrance. With injury (trauma, repetitive strain), the retinaculum can become a site of tendon restriction, nerve impingement, and circulatory compression. Injury to the retinaculum will cause mechanical and neurological damage.
How do you treat retinaculum?
When this fascia becomes inflamed or injured during sports, running, or standing for long periods of time the ankle can become extremely painful and stiff. Treatment: Rest, icing, and, compression socks to bring down swelling are generally the top recommended treatments for a strained flexor retinaculum.
What does the retinaculum do?
A retinaculum (plural retinacula) is a band of thickened deep fascia around tendons that holds them in place. It is not part of any muscle. Its function is mostly to stabilize a tendon. The term retinaculum is New Latin, derived from the Latin verb retinere (to retain).
What is a retinaculum tear?
In type II injuries, the superior peroneal retinaculum is torn off its attachment to the fibula. In type III injuries, a small bony fragment avulses off the distal fibula along with the superior peroneal retinaculum. In type IV injuries, the retinaculum is torn off its posterior attachment to the calcaneus.
What is the function of the superior extensor retinaculum?
The structure indicated is the superior extensor retinaculum of the leg. Retinacula (retinaculum singular) are bands of connective tissue which surround tendons and hold them in place. They function to stabilise tendons as the muscles to which they attach contract to cause movement.
What is the extensor retinaculum?
The extensor retinaculum of the wrist is the broad ligamentous sheet located at the dorsal aspect of the wrist and functions to keep the extensor tendons in alignment and prevent bowstringing during movement.
Is the superior extensor retinaculum a tendon?
Superior extensor retinaculum: This structure holds in place tendons from the following muscles; tibialis anterior, extensor digitorum longus, extensor hallucis longus, and peroneus tertius.
Why does my flexor retinaculum hurt?
Grade I tear: a minor tear,in which only a few fibers are damaged
What does the inferior extensor retinaculum do?
The inferior extensor retinaculum is the lower band of extensor retinaculum that attaches horizontally to the calcaneus (heel bone) and passes over and under the extensor muscle tendons in the ankle.
What is an extensor tendon injury?
Extensor tendonitis is inflammation of the extensor tendons which run along the top of the foot. It is an overuse injury which is common in runners, especially if your shoes do not fit properly, or are laced too tight. Here we explain the symptoms, causes, and treatment of extensor tendonitis and tendinopathy.
Is the anterior tibialis tendon a flexor or extensor?
The tibialis anterior muscle is flexor, inverter (in addition to posterior tibial muscle) and adductor (in addition to the long extensor of hallux) of the foot. Also Know, is Achilles tendon a flexor or extensor? It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone.
