Severe pain in the elbow, tenderness and swelling

Introduction The clavicular fracture showed local swelling, pain and tenderness.

Cause

Most of the clavicle fractures are caused by indirect violence, often caused by the fall of the shoulders, and those caused by direct violence are rare. "Ji Zong Jin Jian. The essence of the heart and the heart of the law" : "Beat damage, or riding a horse, because the object falls to the ground, break the bone." The clavicle fracture is mostly due to falling outside the shoulder or the palm of the hand first, The external force is transmitted to the clavicle through the acromioclavicular joint, and the short oblique fracture is more.

After the fracture, the medial segment was displaced by the sternocleidomastoid muscle, which was displaced more posteriorly and upwardly. The lateral segment was displaced forward and downward due to the gravity of the upper limb and the pectoralis major muscle. Most of the clavicle fractures in children are green branch fractures, and the fractures tend to be angled upwards. Direct violence often causes cross-cutting or crushing fractures. If the fracture is severely displaced, the brachial plexus and the subclavian artery and vein behind the clavicle may be combined with injury.

Generally, there is a clear history of trauma, local swelling, pain, tenderness are more obvious, shoulder joint activity is limited, the upper limb abduction and lifting of the affected side are limited, and the displaced end often has a bulge deformity. The patient's head is inclined to the affected side, and the lower jaw is biased to the healthy side, which relaxes the sternocleidomastoid muscle and reduces pain. Young patients are not easy to touch after fracture, especially the green branch fracture, the clinical manifestations are not obvious, but when they are dressed, raised their hands or lifted from the armpits, they will cry because of the increased pain. X-ray examination can show the type of fracture. And the degree of shift.

Differential diagnosis

Swelling and tenderness of the elbow: intercondylar fracture of the humerus, severe pain after trauma to the elbow joint, extensive tenderness, obvious swelling, and may be accompanied by subcutaneous congestion.

Elbow pain: external humeral epicondylitis, iliac crest nerve vascular bundle is embedded in the elbow can cause elbow pain.

Abdominal elbow swelling and dysfunction: half of the radial head fracture is also called Hahn-steinthal fracture, symptoms and signs: elbow lateral swelling, elbow flexion and extension dysfunction.

Elbow sprain: The elbow sprain is mostly under the action of external force, causing the elbow to have an abnormal range of motion, causing damage to the medial and lateral collateral ligaments of the elbow.
