humeral head fracture
Introduction
Introduction to radial head fracture Simple humeral head fractures are rare and are an intra-articular fracture, mainly due to indirect external forces. Fractures are more common in young adults and occasionally in old age. According to the different degrees of fracture, it can be divided into three types: humeral head fracture, humeral head fracture and dislocation and comminuted humeral head fracture. basic knowledge The proportion of sickness: 0.6% Susceptible people: more common in young adults Mode of infection: non-infectious Complications: comminuted fracture
Cause
Cause of humeral head fracture
(1) Causes of the disease
Mostly caused by strong direct violence.
(two) pathogenesis
Similar to the occurrence of a direct violent rupture of the humeral large tuberosity fracture, that is, the violence from the side is too fierce, which can cause large nodules and humeral head fractures at the same time; or this violence does not cause a large nodule fracture, but continues Inward conduction leads to fracture of the humeral head. The fracture of the former is mostly comminuted, while the latter is more common with the compression type.
Prevention
Radial head fracture prevention
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
Radial head fracture complications Complications, comminuted fractures
No complications at present.
Symptom
Symptoms of humeral head fractures Common symptoms Neck muscle swelling and hardening Shoulder movement limitation Comminuted fractures Deformation of fractures of bones
Because of the intra-articular fracture, the clinical symptoms are slightly different from the large tibial tuberosity fracture.
1. Swelling: diffuse swelling of the shoulder joint, the range is large, mainly due to local traumatic reaction and fracture end hemorrhage accumulated in the shoulder joint cavity, embedded type is less bleeding, so local swelling is also light.
2. Pain and conduction pain: In addition to local pain and tenderness, sniper elbows can cause shoulder pain.
3. Restricted activities: The scope of its activities is obviously limited, especially those with comminuted fractures. The fractures are more embedded, the fracture ends are relatively stable, and the restrictions are lighter.
Examine
Examination of humeral head fracture
X-ray examination can determine the diagnosis.
Diagnosis
Diagnosis and diagnosis of radial head fracture
diagnosis
According to the history of trauma, clinical symptoms of shoulder swelling, pain and conduction pain, limited mobility and X-ray plain film diagnosis, no difficulty, X-ray film should include positive and lateral position to determine the displacement of the fracture end.
Differential diagnosis
Separation of the distal radius of the humerus is a rare osteophyte injury in the elbow joint of children. The ossification center of the epiphysis has not completely appeared before the osteophyte separation, and it is easy to be confused with the external humeral fracture and elbow dislocation. The ossification center is all misdiagnosed as a transforaminal fracture. The distal humerus epiphysis consists of the external iliac crest, the trochlear, the upper iliac crest, and the superior iliac crest. The external humerus and the humeral carpal skeleton are integrated by cartilage, so the part is weak. Usually, violence can cause a fracture of the external cartilage junction of the humerus, which is a fracture of the lateral malleolus. But sometimes the external force can separate the osteophytes of the distal radius. The two are not exactly the same in treatment. The former often requires open reduction of the operation, and the separation of the whole bone can be reduced by closed manipulation. Such damage is easy to be misdiagnosed and missed. If the treatment is improper, it will cause severe elbow varus in the elbow joint deformity and affect the function.
The surgical neck of the humerus is located 2 to 3 cm below the anatomical neck and above the pectoralis major. Here, the transition from cancellous bone to dense bone is slightly thin, which is an anatomical weak link. The fracture is more common and can occur at various ages. More elderly people, more severe surgical neck fractures of the humerus, more local bleeding, should pay special attention.
