How does fracture recover quickly?
Fracture refers to the continuous complete or partial fracture of bone structure. More common in children and the elderly, young and middle-aged people also occur from time to time. Patients usually have one fracture, and a few have multiple fractures. After timely and proper treatment, most patients can recover their original functions, and a few patients can leave different degrees of sequelae.
The typical manifestations of fracture patients are local deformation after injury, abnormal limb movement and bone friction when moving limbs. In addition, the wound has severe pain, local swelling and congestion, and dyskinesia occurs after the injury.
The ultimate goal of fracture treatment is to restore the function of the injured limb to the maximum extent. Therefore, the three basic principles of reduction, fixation and functional exercise are very important in fracture treatment.
1. Reset
It is to restore the displaced fracture end to normal or close to the original anatomical relationship after fracture, so as to restore the scaffold function of bone. The reduction methods include closed reduction and surgical reduction.
repair
Fracture is easy to be displaced again because of instability after reduction, so different methods should be used to fix it in a satisfactory position and make it heal gradually. Commonly used fixation methods include: small splint, plaster bandage, external fixation bracket, traction braking fixation and so on. These fixation methods are called external fixation. If it is surgical incision, it is fixed with steel plate, steel needle, intramedullary needle, screw, etc. This is called internal fixation.
3. Functional exercise
Through the muscle contraction of the injured limb, the blood circulation of the tissues around the fracture is increased, the fracture healing is promoted, the muscle atrophy is prevented, and the joint adhesion and joint capsule contracture are prevented by actively or passively moving the unfixed joint, so that the function of the injured limb can be restored to the normal state before the fracture as soon as possible.
There are three main reasons for fracture:
1 direct violence
Violence directly acts on a certain part of the bone, resulting in fracture of the injured part, often accompanied by different degrees of soft tissue injury. If the wheel hits the lower leg, the tibia and fibula will break at the impact.
2. Indirect violence
Indirect violence causes distant fractures through longitudinal conduction, leverage or torsion. For example, when the foot falls from a height and touches the ground, the trunk bends forward sharply due to gravity, and the vertebral body at the junction of thoracolumbar vertebrae is compressed or burst.
3. Cumulative strain
Long-term, repeated and slight direct or indirect injuries can lead to fractures in specific parts of limbs, also known as fatigue fractures. For example, long-distance walking can easily lead to fractures of the second and third metatarsal bones and the subofibular 1/3 diaphysis.
