comminuted fracture
Introduction
Introduction Comminuted fracture is a complete fracture. The fracture of the finger bone is more than three pieces. It is also called t or y type fracture. The open fracture refers to the fracture of the skin or mucous membrane at the fracture site, and the fracture end is connected with the outside. Simple femoral head fractures are rare and are often part of hip injury, such as posterior dislocation of the hip and femoral head fracture. A comminuted fracture of the femur can cause a person to become a scorpion. The fractures of the extremities, especially the rehabilitation of joints and joints around the joints, the most important is the training of joint mobility and muscle strength.
Cause
Cause
A fracture is a disease in which bone is partially or completely broken due to trauma or pathology. The main clinical manifestations are: localized pain and tenderness in the fracture, local swelling and ecchymosis, partial or complete loss of limb function, and complete deformity and abnormal activity of the complete bone.
Examine
an examination
The purpose of fracture classification is to clarify the location and nature of the fracture, and to diagnose and select appropriate treatment methods in a clinically correct and comprehensive manner.
(1) According to whether the fracture is connected with the outside world, it can be divided into:
1. Open fracture: The skin and mucous membranes near the fracture are ruptured, the bladder or urethra rupture caused by the pubic fracture and the rupture of the rectum caused by the fracture of the tailbone are all open fractures. Such fractures are contaminated by communication with the outside world.
2. Closed fracture: The skin or mucosa of the fracture is intact and does not communicate with the outside world. Such fractures are not contaminated.
(2) Classification according to the degree of fracture
Complete fracture
The integrity or continuity of the bone is completely interrupted, and the fracture of the tubular bone forms a distal, nearly two or more fracture segments. Transverse, oblique, spiral and comminuted fractures are all complete fractures.
2. Incomplete fracture
The integrity or continuity of the bone is only partially interrupted, such as fractures of the skull, scapula and long bones, and children's green branch fractures are incomplete fractures.
Diagnosis
Differential diagnosis
Differential diagnosis of comminuted fractures:
1. Compression fracture: Compression fracture, cancellous bone deformed by compression, such as vertebral body and calcaneus.
2, avulsion fracture: the internal humeral fracture of the humerus is common in sports injuries such as falling or throwing on the ground. When the fall, the forearm extends and abducts, and when the forearm flexor contractes fiercely, the upper jaw of the humerus is pulled by the flexor muscles to cause avulsion fracture.
3, spiral fracture: spiral fracture is a complete fracture. Complete fracture refers to the complete interruption of the integrity or continuity of the bone. After the fracture of the tubular bone, it forms a distant, nearly two or more fracture segments.
