Ligament Collateral Ulnar

The ulnar collateral ligament (l. collaterale ulnare) is an anatomical structure that connects the ulna to the radius in the area of ​​the elbow joint. It plays an important role in stabilizing the joint and ensuring its mobility.

The ulnar collateral ligament consists of two parts: medial and lateral. The medial part is located on the inner surface of the ulna, and the lateral part is located on the outer surface of the radius. Both parts are connected by fibers that run along the lateral surface of the joint.

When the joint is at rest, the fibers of the ulnar collateral ligament are taut and provide stability to the joint. However, as the joint moves, the fibers relax and allow the joint to move freely.

The importance of the ulnar collateral ligament is that it protects the joint from damage and ensures its normal functioning. If the ligaments are damaged or weakened, it can lead to various elbow diseases such as arthritis, bursitis, etc.

Surgery or physical therapy may be required to treat elbow joint problems and restore normal function. However, it is important to remember that proper strengthening of the elbow collateral ligament is key to preventing further damage to the joint.

Collateral radial ligament (Dupuytren's ligament)

The collateral, or ulnar, carpal ligament is an elastic tendon that connects the radial and middle fingers of a person. It plays an important role in maintaining the structural stability of the wrist and hands and prevents the occurrence of carpal deformities and injuries.

Typically, this ligament is located inside the wrist, but can also be stretched outside its rounded shape. In addition, it can have several varieties, for example, transverse, cutaneous, transverse cutaneous, etc., which causes several variations of the ligament during examination.

An important risk factor for wrist dysfunction is trauma to the hand or wrist. Patients who have experienced trauma should pay attention to how they feel in the wrist and experience discomfort if signs of ligament dysfunction are detected.

Functions of the collateral ligament:

- Allows the hand to hold up to nine objects without excessive fatigue; - Helps speed up hand movements; - Prevents wrist injury due to shifting arm radius during movement. If the stability of the elbow is impaired, the collateral ligament causes the palm of the hand to shift relative to the elbow, while the fingers lose mobility, and extension and rotation of the forearm becomes difficult. In these conditions, it is important to consult a traumatologist to determine the extent of the disorder and prescribe conservative treatment (in the case of mild displacement) or surgical intervention (in the presence of more serious lesions).

Modern treatment of the consequences of collateral ligament disorders is most often aimed at ensuring full functionality of the limb and maintaining its anatomical location. To achieve this, various orthopedic procedures and surgical interventions are performed to stabilize the position of the wrist. The surgical approach may include strengthening the collateral ligament with special materials, suturing, fixing the injury site, and immobilizing the limb. In this case, an individual approach and a specialist decision are always needed
