Distal radial epiphysis separation

Introduction to the separation of the distal radius of the humerus In the human osteophyte injury, the distal part of the humerus is the most prone to occur, accounting for almost half of the total osteophyte injury, that is, 40% to 50%. basic knowledge Sickness ratio: 0.0012% Susceptible people: no special people. Mode of infection: non-infectious Complications: distal radius fracture

The cause of osteophyte separation in the distal radius

(1) Causes of the disease

Mostly caused by indirect violence.

(two) pathogenesis

Similar to the distal sacral Collis fracture, individual cases are similar to Smith's fractures, mostly from the palm or the back of the hand.

Prevention of osteophyte separation in the distal radius

The prognosis of the general case is better. A few cases of heavier injury and improper treatment may cause the mandala-like deformity of the ulnar long tibia short wrists after several years of osteophyte closure. This malformation may cause inconvenience and pain to the patient. The resection is corrected.

Complications of distal humerus epiphysis Complications distal radius fracture

In severe cases, if the treatment is not correct, the epiphysis may be closed early.

Distal humeral epiphysis separation symptoms Common symptoms Wrist swelling and pain in the temporal part of the wrist

1. Fracture symptoms show swelling, pain and tenderness (mostly ring-shaped) in the back of the wrist after trauma.

2. Other symptoms include limited wrist movement and fork-shaped deformity on the affected wrist.

From the X-ray film, it is divided into the following 5 types).

The type I fracture line passes completely through the weak zone of the tarsal plate. This type is rare, accounting for about 10%.

Type II is similar to the former, but one triangular fracture piece is often torn off at the edge of the bone. This type is the most common, accounting for about 70%.

The type III fracture line enters the epiphysis from the articular surface to the epiphyseal plate, and then is weakly along one side to the edge of the epiphyseal plate. This type is rare.

Type IV is similar to the former, except that the fracture line extends from the articular surface into the tarsal plate and continues to extend through the weak zone to the end of the epiphysis, forming a similar displacement of the Barton fracture; and the fracture piece is unstable and easily displaced, this type rare.

V-type is compression type, that is, compression fracture of epiphyseal cartilage plate. This type of diagnosis mainly relies on the doctor's clinical experience, and is easily missed. It will not be discovered until the early formation of osteophytes in the late stage, and it will be discovered when the development is stopped. For the pain after trauma to the wrist, there is an annular tenderness along the epiphysis line. All such injuries should be considered and treated with reduction and fixation.

Examination of the separation of the epiphysis of the distal radius

No relevant laboratory tests.

The X-ray film can show the separation of the epiphysis and its type; in general, the bilateral wrists should be taken and the segments should be used for comparison.

Diagnosis and differentiation of the distal radius of the humerus

1. The history of trauma is caused by falls on the ground.

2. The clinical manifestations are completely consistent with distal radius fractures, including fork-shaped malformations, swelling at the wrist joints, pain, tenderness and limited mobility.

3. Imaging examination X-ray film can show the separation of the epiphysis and its type; in general, the bilateral wrist joints should be taken for comparison.
