Greater tuberosity fractures of the humerus
Introduction
Introduction to the treatment of humeral large tuberosity Large tibial tuberosity fractures, a few occur separately, most of them are complicated by anterior dislocation of the shoulder joint, so the diagnosis should be paid attention to the angle of joint dislocation. basic knowledge The proportion of illness: 0.09% Susceptible people: good for young adults Mode of infection: non-infectious complication:
Cause
Causes of tibial tuberosity fracture
(1) Causes of the disease
Mostly direct violence, caused by indirect violence.
(two) pathogenesis
According to the traumatic violence and combined injuries can be divided into four types:
1. Non-displaced simple humeral large nodular fractures: most of these fractures are direct violent impact on the greater tibia of the humerus, that is, when the fall occurs on the lateral side of the shoulder, the fracture is rarely severely displaced or displaced. .
2. The tibiofibular tuberosity fracture with anterior dislocation of the shoulder joint: When the fracture is anterior dislocation of the shoulder joint, the large nodule is caused by the anterior lower edge of the scapula, because the periosteum of the large nodule and the tibia is not broken, and the shoulder joint After the anterior dislocation, the large tibial tuberosity is also self-resetting.
3. Displaced simple avulsion fracture: This type of fracture is mostly caused by indirect violence. That is, when it falls, the upper extremity abducts and rotates to the ground, and the upper and lower muscles, the small round muscle and the rotator cuff suddenly contract and pull the humerus. Nodular avulsion fracture, if it is a complete avulsion fracture, the fracture block can be retracted above the articular surface of the humeral head.
4. Large nodular fractures of the surgical neck fracture of the humerus: mostly caused by indirect violence. If the hand or elbow touches the ground during the fall, the violence will hit the shoulder along the upper limb, which may cause the fracture of the surgical neck and large nodules of the humerus.
Prevention
Prevention of humeral great nodule fracture
There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.
Complication
Complications of humeral greater tuberosity fracture Complication
There is no complication of this disease.
Symptom
Symptoms of humeral nodular fractures Common symptoms Neck muscle swelling and hard shoulder movement limitation
Pain
There is pain and tenderness below the shoulder, but there is no obvious conduction pain.
2. Swelling
Due to local bleeding and traumatic reaction of the fracture, it showed swelling under the shoulder and limited mobility. 3. The joint activity was limited, especially when the external rotation was performed.
Examine
Examination of large tibial fractures of the tibia
X-ray film can show fracture and displacement.
Diagnosis
Diagnosis and diagnosis of large tibial tuberosity fracture
1. History of trauma: more common in life and traffic (most walks slipped) accidents.
2. Clinical manifestations, mainly shoulder swelling, pain and activity limitation.
3. The imaging examination is mainly X-ray plain film, including the right position, lateral position and axial position. Generally, CT and MRI examinations are not required.
In the local hemorrhage and traumatic reaction of the fracture, the swelling under the shoulder is indicated, and the activity is limited. 3. The joint activity is limited, especially when the external rotation is performed.
