Intercondylar fracture of humerus
Introduction
Introduction to the intercondylar fracture of the humerus The intercondylar fracture of the humerus is a serious injury to the elbow joint, which occurs in young people and in the prime of life. This kind of fracture is often comminuted, difficult to close and reset, open reduction and lack of effective internal fixation, which is not uncommon for elbow joint dysfunction, nonunion or malformation. It will have a serious impact on elbow joint function, no matter how closed. Reset, or surgery open reduction, the final results are not satisfactory. basic knowledge The proportion of illness: 2.1% Susceptible people: no special people Mode of infection: non-infectious Complications: vascular injury
Cause
Causes of intercondylar fractures of the humerus
(1) Causes of the disease
Both direct and indirect violence can cause an intercondylar fracture of the humerus.
(two) pathogenesis
When falling, the elbow joint is in the extended position, the palm and the human body are gravity upward, and the lower hand is transmitted and concentrated in the humerus, and the violence acts on the ulna. The upward impact causes the humerus to split and the lateral iliac cleft, separating to the sides, causing fractures and fractures. The proximal end is displaced forward, and the distal end of the fracture splits into two or more pieces and is displaced rearward.
When the elbow joint is in the flexion position, it directly hits the ground. It may also be caused by the upward impact of the olecranon. The olecranon is triangular in cross section. When the part is violently transmitted, the olecranon is like a wedge hitting the inner and outer trochlear grooves. The separation between the two jaws is caused, and the lower end of the tibia is displaced forward.
Prevention
Prevention of intercondylar fracture of the humerus
The disease is mainly caused by trauma, and should be avoided in normal life.
Complication
Complications of humeral intercondylar fracture Complications, vascular injury
Sometimes it can be combined with neurovascular damage.
Symptom
Symptoms of intercondylar fractures of the humerus Common symptoms Severe pain Swelling of the elbows Sickness Elbow sprain elbow pain Elbow joints can not flex the elbow lateral swelling and dysfunction
There is severe pain after elbow joint trauma, extensive tenderness, obvious swelling, may be accompanied by subcutaneous congestion, severe fracture displacement may have a wide transverse diameter of the lower end of the humerus, overlapped shifting may have upper arm shortening deformity, elbow joint is half Stretching, forearm pronation, triangular bone structure disorder behind the elbow, can touch the fracture block, bone rubbing is obvious, sometimes combined with nerve, vascular injury, should pay attention when checking.
Type I: There is no separation and displacement of the fracture.
Type II: The fracture has a slight separation and displacement, but the two tendons have no rotation.
Type III: The fracture is separated and the two tendons are rotated.
Type IV: The fracture is comminuted and the joint surface is severely damaged.
Examine
Examination of the intercondylar fracture of the humerus
The X-ray of the lateral elbow can confirm the diagnosis and show the type of fracture and the degree of displacement.
Diagnosis
Diagnosis and diagnosis of intercondylar fracture of humerus
Traumatic history, severe pain in the elbow after injury, extensive tenderness, obvious swelling, elbow in semi-extension, forearm pronation, triangular bone structure disorder behind the elbow, can touch the fracture block, bone rubbing is obvious, elbow positive lateral position X The line can be clearly diagnosed and shows the type of fracture and the degree of displacement.
