The three main causes of elbow dislocation

A dislocated elbow is very important to treat promptly so that it does not affect your daily work and life, but first you need to know why you have a dislocated elbow together and how to treat it so that you can make the most of it!

Causes of elbow dislocation

The first cause is the predominantly adolescent population and may be caused by indirect violence. Generally when a person falls, the palm of the hand lands on the ground and the elbow joint is fully extended, this joint is subjected to an instant increase in force, which may lead to joint effusion and dislocation of the elbow joint.

The second cause may be that as people age, some people's bones calcify significantly and there is a lack of joint lubricating fluid in the joint, due to people moving around a lot and not paying too much attention to the strength of the key use in ordinary life. This leads to increased friction, which over time can result in dislocation of the elbow joint.

The third cause is joint dislocation caused by direct violence, which may be caused by some accident in life, such as say a car accident or other causes of elbow dislocation, and the fourth cause is split elbow dislocation, which is caused by the ability to put the ring around the movement excessively.

Treatment of dislocated elbow joints

Indications for surgery: (1) those who have failed closed repositioning, or those who are not suitable for closed repositioning, this is rare, but mostly combined with serious injuries to the elbow, such as ulnar hawkbone fractures with separation and displacement; (2) elbow dislocation combined with avulsion fractures of the medial epicondyle of the humerus, when the elbow dislocation is reset, but the medial epicondyle of the humerus is still not reset, surgery should be performed to reset the medial epicondyle or internal fixation; (3) old elbow dislocation, not suitable for trial (iii) old dislocations of the elbow that are not suitable for closed reduction: (iv) certain habitual dislocations.

Open repositioning: Brachial plexus anaesthesia, longitudinal incision behind the elbow, exposure of the medial epicondyle of the humerus and protection of the ulnar nerve. A lingual incision is made for the triceps tendon. After exposing the elbow joint, the surrounding soft tissue and scar tissue are peeled away to remove haematoma, granulation and scarring from the joint cavity. The bony end of the joint is identified and repositioned. The periarticular tissues are sutured. To prevent re-dislocation a kerf pin is placed from the hawk's beak to the lower end of the humerus and removed after 1 to 2 weeks.

Arthroplasty: Mostly used for old dislocations of the elbow joint where the cartilage surface has been destroyed, or where the joint is stiff after an injury to the elbow. Under brachial plexus anaesthesia, a posterior elbow incision is made, the triceps tendon is incised and the bony ends of the elbow joint are exposed. The lower end of the humerus is excised, a portion of the medial and lateral condyles of the humerus are preserved, the tip of the ulnar eminence and part of the dorsal bone are excised, and the tip of the rostral process is also cut smaller, preserving the articular cartilage surface. The radial head is not excised if it does not affect joint movement, otherwise the radial head is excised. If the new joint gap is narrow, the central part of the lower humerus may be removed by 0.5 cm to create a split right. The ideal gap distance should be 1 to 1.5cm.

Elbow Dislocation Prevention

In addition, it should be noted that patients with dislocated joints should move their joints early and take the initiative to do extension and flexion and forearm rotation activities or supplement with physiotherapy after the release of fixation, but excessive forceful pulling is prone to ossifying myositis around the elbow joint.
