Smith's fracture
Introduction
Introduction to Smith's fracture The smithfracture site is the same as the Colesi fracture, but the deformity is opposite to the Colesi fracture, and the distal end is displaced to the volar side. It can also be combined with dislocation of the lower ankle joint, so it is also called anti-Coles fracture. Emett & Breck (1958) counted 471 cases of wrist fractures, 448 cases of Clays fractures, and 23 cases of Smith fractures, 19.5:1. basic knowledge The proportion of illness: 0.002% Susceptible people: no special people Mode of infection: non-infectious complication:
Cause
Smith fracture cause
(1) Causes of the disease
Mostly caused by direct violence.
(two) pathogenesis
The most common reason in the past is that the car driver suddenly loosened his hand when shaking the engine and was directly hit by the reversed handle. At present, this phenomenon has disappeared, and it is more common in impact trauma (such as riding a coupe or a motorcycle) or the back of the wrist. Caused by the fall of the ground.
Prevention
Smith fracture prevention
Most of the functional recovery of the general case is more ideal than the ideal joint, and those with poor resettlement may have sequelae.
Complication
Smith fracture complications Complication
Hand numbness, residual plant type fracture pain, deformity.
Symptom
Smith fracture symptoms common symptoms wrist pain
Symptoms are similar to the Coles's fracture. The wrist deformity is opposite to the Coles's fracture. The distal end of the fracture is flexed to the volar arm. The distal radius of the humerus is facing the dorsi of the volar fracture. The proximal part of the fracture protrudes to the dorsal side. Lateral X-ray film can be diagnosed.
Classification: Generally, it can be divided into the following two types in clinical practice.
1. External joint type refers to the fracture line does not affect the articular surface, the most common, the fracture line is mostly horizontal, a few are oblique, the latter is more difficult to maintain alignment after reset, more need to add finger traction.
2. Joint involvement type All fractures and joints belong to this type. Because Smith fractures are rare in clinical practice, it is not necessary to further classify such patients.
Examine
Smith's fracture examination
The positive side X-ray of the wrist can be used to determine the diagnosis.
Diagnosis
Smith fracture diagnosis
History of trauma, local swelling, pain, deformity, fracture of the distal end of the fracture to the volar wrist is flexed, the distal end of the humerus protrudes to the dorsal side, and the lateral lateral wrist X-ray film can be clearly diagnosed.
