The typical manifestations of fracture patients are local deformation after injury, abnormal movement of limbs, and bone rubbing when moving limbs. In addition, the wound has severe pain, local swelling and congestion, and dyskinesia occurs after the injury.

Unique signs of fracture:

(1) Deformity and displacement of the fracture end can change the shape of the affected limb, mainly manifested as shortening, angulation and lengthening.

(2) Abnormal activity occurs in the parts where limbs can't move under normal circumstances, and abnormal activity occurs after fracture.

(3) Bone rubbing sound or bone rubbing feeling, and the two fractured ends rubbing against each other after fracture can produce bone rubbing sound or bone rubbing feeling.

the diagnosis can be made only if one of the above three signs is found, but the possibility of fracture, such as embedded fracture and fissure fracture, cannot be ruled out if these three signs are not seen. In general, don't check the above signs for diagnosis, because it will aggravate the injury.

Examination:

1. X-ray examination

Anyone who is suspected of fracture should have a routine X-ray examination, which can show incomplete fracture, deep fracture, intra-articular fracture and small avulsion fracture that are difficult to find in clinic. Even if the fracture is obvious in clinic, X-ray examination is necessary, so that the type of fracture can be understood.

X-ray films should include frontal and lateral films, and must include adjacent joints. Sometimes, X-ray films of oblique, tangential or healthy positions should be taken.

2. CT examination

CT examination is feasible for those whose fractures are unclear but cannot be ruled out, those whose spinal fractures may compress spinal nerve roots and those with complex fractures. Three-dimensional CT reconstruction can classify fractures more intuitively and conveniently, which is very helpful to the choice of treatment scheme. At present, it is commonly used in clinic.

3. MRI examination

Although the fracture line is not as good as CT examination, it has unique advantages in showing spinal nerve roots and soft tissue injuries, and has been widely used in the examination of spinal fractures.
