What is Extensor retinaculum?
The extensor retinaculum is an oblique strong band consisting of muscle fibers located in the distal forearm’s fascia. It crosses to affix to the pisiform and triquetral wrist bones and attaches to the radius’ later border. While crossing the radius’ posterior surface, it binds to the bone elevations and makes 6 tunnels that transmit tendons underlying it and to the hand and the wrist. Synovial tendon sheaths, which keep the extensor tendons safe from excessive friction, line these tunnels.
It is also referred to as:
Superior Extensor Retinaculum
The superior extensor retinaculum is a standard transverse fiber arrangement in the anterior crural fascia that assists in binding the crus’ extensor tendons to the tibia. It can help avoid bowing away of the tendons from the bone while the related musculature contracts.
It is known as Retinaculum musculorum extensorum superius pedis in Latin and as Rétinaculum supérieur des muscle extenseurs in French.
Inferior Extensor Retinaculum
The inferior extensor retinaculum refers to a standard arrangement of oblique fibers within the anterior crural fascia, which allows the crus’ extensor tendons to bind to the tibia.
In Latin, it is known as Retinaculum musculorum extensorum inferius pedis and in French, it is referred to as Rétinaculum inférieur des muscle extenseurs.
Extensor Retinaculum Injury
The cases of extensor retinaculum injury are of two types:
Inferior Extensor Retinaculum Injury
It can be injured or strained in case the ankle is put under excessive pressure. Inferior Extensor Retinaculum Strain or inferior extensor retinaculum sprain can be usually observed in athletes who run and sprint. It is also common in people who put their ankle undue pressure such as when an object hits their ankle, when they twist their ankle by slipping and falling off a curb or when they stand for a long time. Such strains can be conservatively treated with wraps and supportive measures like heat therapy, ice and coolants.
Some of the main Inferior Extensor Retinaculum Strain symptoms include:
Inferior Extensor Retinaculum Strain can result from injuries leading to the tendons or ligament being torn or due to inflammation of muscles and tendons caused by some medical conditions.
Inferior Extensor Retinaculum Strain treatment involves rest, full immobilization of the impacted foot, use of NSAIDs and even surgery in very rare cases. Strained Inferior Extensor Retinaculum recovery period is around 2 weeks from the time of immobilization.
Superior Extensor Retinaculum Injury
Superior extensor retinaculum happens to be the ligament running along the feet top, and stabilizes other feet ligaments. It also supports feet movements occurring while running. Superior extensor retinaculum pain might indicate tissue damage, and injury could be worsened if the pain is ignored.
Since this ligament also interacts with various other tendons located in the lower body, pain and injury here can also have other impacts. Ignoring pain and injury in this ligament can heighten risks of damage to the muscles and tendons running along the shins.
Superior extensor retinaculum pain is generally localized along the front section of the ankle and foot. In a few cases, superior extensor retinaculum damage can affect muscular motions and prevent the ankle from moving completely. As this ligament interacts with tendons attached to the muscles of the shin area, the muscular functioning in the shins might be abnormal. Ignoring the injury might worsen the effect of the superior extensor retinaculum on muscular function.
Superior extensor retinaculum treatment is needed if pain is felt while running. Going on running can exacerbate your ligament even more, and eventually cause damage to other leg, foot and ankle tissues. For treating extensor retinaculum exercises might be designed for improving ankle and foot strength and allowing healing of the ligament, so that running is possible after some time without any risks of injury.
Extensor Retinaculum Hand Pain
Extensor retinaculum, in the arm, can be found in the forearm’s posterior section – close to the wrist joint. There can be reduced extensor muscle mobility and acute pain in patients with retinaculum or trauma or diabetes. Underlying conditions such as diabetes can delay the healing process, and consequently prolong the discomfort and pain.
Extensor Retinaculum Wrist Pain
Athletes and sportspersons who often use their wrist joint commonly suffer from damage to the wrist joint’s extensor retinaculum. The problem is common in cricketers, tennis players etc. While managing wrist pain related to sports activities, it is important to make ergonomic considerations. Doctors should work along with technicians for designing equipments that can help minimize wrist damage.
Rest and physiotherapy of the wrist joint has been proven effectual in lessening extensor retinaculum pain, although athletes can suffer from higher risks of recurrent wrist pain.
Extensor Retinaculum Foot Pain
Extensor Retinaculum foot pain issues mainly result from disorders or injuries, or both. Inferior extensor retinaculum pain commonly results from various injuries involving the extensor retinaculum of foot that can lead to muscle, ligament or tendon tear, or twists, fractures, strains, bruises and sprains.
