Acromioclavicular ligament

The acromioclavicular ligament (lat. ligamentum acromioclaviculare) is a ligamentous structure that connects the collarbone and scapula at the shoulder joint. It is one of the key ligaments that provides stability to the shoulder girdle.

The acromioclavicular ligament is shaped like a flat band and consists of a bundle of fibers that extend from the acromion of the scapula to the outer end of the clavicle. The ligament is formed from the inner and outer parts, which connect at the collarbone.

The functions of the acromioclavicular ligament are to provide stability to the shoulder joint and transfer load from the hand and forearm to the torso through the shoulder girdle. It is also involved in maintaining the correct anatomical shape of the shoulder girdle.

If the acromioclavicular ligament is injured, it can be stretched, torn, or damaged. This can lead to severe shoulder pain, limited arm elevation, and impaired shoulder girdle function.

Various techniques are used to diagnose acromioclavicular ligament injuries, including x-rays, magnetic resonance imaging, and ultrasound.

Treatment for acromioclavicular ligament injuries depends on the extent of the injury and may include conservative therapy with physical therapy and rehabilitation exercises, as well as surgery in severe cases.

Thus, the acromioclavicular ligament plays an important role in stabilizing the shoulder girdle and transferring load from the hand and forearm to the trunk. Damage to it can lead to serious consequences, so it is important to promptly seek medical help if symptoms appear.

The acromioclavicular ligament (lat. l. acromioclaviculare, PNA, BNA, JNA) is a ligament in the human skeleton that connects the clavicle to the acromion of the scapula. It plays an important role in the stability of the shoulder joint and provides stability to the scapula.

The acromioclavicular ligament consists of two parts: dense fibrous tissue and elastic fibrous material. Fibrous tissue forms the basis of the ligament and connects the clavicle and the acromion of the scapula. The fibrous material provides elasticity to the ligament and allows it to adapt to different movements of the shoulder joint.

The key function of the acromioclavicular ligament is to provide stability to the shoulder joint, which is especially important when performing sports activities or jobs that involve heavy loads on the shoulder. When the acromion and clavicle are connected, it provides stability to the shoulder joint during movement.

However, if the acromioclavicular ligament is damaged, it can lead to decreased stability of the shoulder joint and the development of various diseases such as impingement syndrome, bursitis or tendinitis.

Overall, the acromioclavicular ligament plays an important role in maintaining the stability of the shoulder joint and allowing the joint to function properly. Damage to it can lead to serious consequences, so it is important to take care of the health of this ligament and perform exercises to strengthen it.
