Patients with internalization of the humerus, i.e., internalization of the surgical neck fracture of the humerus, typically develop angular displacement of the fracture ends inward, and the fracture ends are often embedded in each other medially. The treatment needs to be fixed or even internal fixation surgery.
1. Surgical neck of humerus fracture internalized type, is a relatively rare type of surgical neck of humerus fracture. The mechanism of injury is that the upper limb is adducted when falling, so that the distal segment of the fracture is adducted, and the proximal segment is adducted accordingly, resulting in the inward angular displacement of the two fracture ends.
The two fracture ends are often embedded in each other medially, i.e., when the upper arm is affected by the violence of internalization in the state of internalization, the fracture ends become angular deformity to the lateral side.
2. Treatment of internalized humeral surgical neck fracture: Generally, mild deformity or stable fracture does not need to be reset, and the affected limb can be immobilized against the chest for 3 weeks by placing cotton pads under the armpit.
If the angle of deformity is large or the displacement is obvious, the shoulder and elbow joints need to be fixed by manipulation and chest fixation for 4 weeks; if there is soft tissue embedded in the fracture or the fracture is combined with dislocation of the shoulder, manipulation or external fixation fails, it is feasible to have surgical open reduction and internal fixation surgery.
If the patient is suspected of having an internal humeral surgical neck fracture, it is recommended to actively seek medical treatment, exclude or diagnose through X-rays, etc. Patients should not diagnose on their own, so as not to delay the condition.
