depends: extend of injury acute / chronic, age of injury, and age of person if this is an acute tear without subluxation or bowstringing of the tendons then you can treat with a splint - wrist will be in neutral position if it's subluxing or bowstringing with extention of the wrist then you can try a splint and if no better then surgically suture the tear and splint. if this goes untreated then you can lose range of motion hope this helps
The extensor digitorum communis is an extensor of the wrist and fingers. The extensor digitorum communis is the primary extensor of the lateral four fingers IP joint and assists in wrist extension.
The muscles that produce extension of the finger joints and wrist are the extensor muscles. In the forearm, the specific extensor muscles responsible for extension of the fingers and wrist include the extensor digitorum and extensor carpi radialis muscles.
Extension of the wrist is done by both the Extensor Carpi Radialis and the Extensor Carpi Ulnaris muscles, while abduction of the wrist is done by both the Extensor Carpi Radialis and Flexor Carpi Radialis.
The agonist muscles responsible for wrist extension (or hypertension) include the extensor carpi radialis longus, extensor carpi radialis brevis, and extensor carpi ulnaris. These muscles work together to extend the wrist, allowing for movements such as lifting or pushing. They are primarily innervated by the radial nerve. Additionally, the extensor digitorum can assist in wrist extension during finger movements.
Extensor carpi ulnaris
Extensor Carpi Radialis Longus
The extensor muscles of the wrist and digits are responsible for extending the wrist joint and fingers. These muscles work in coordination to help move the hand and fingers upward and away from the palm. Strengthening these muscles can improve wrist and finger mobility and function.
Wrist extension is primarily caused by the contraction of the extensor muscles located in the forearm, particularly the extensor carpi radialis longus, extensor carpi radialis brevis, and extensor carpi ulnaris. These muscles work to pull the back of the hand and fingers upward, increasing the angle between the dorsal side of the hand and the forearm. This movement is often facilitated by the synergistic action of other muscles and tendons around the wrist joint. Additionally, wrist extension can be influenced by the positioning of the fingers and overall hand posture.
The extensor that is considered a one-joint muscle is the extensor carpi radialis longus. Unlike other extensors that cross multiple joints, the extensor carpi radialis longus primarily acts on the wrist joint, aiding in wrist extension and abduction. This specificity allows it to play a key role in wrist movements without influencing the elbow joint.
The flexor carpi radialis is the agonist muscle in wrist flexion. This muscle, know as a wrist flexor, is located in the forearm.
This name implies that it extends the wrist!
