Finger avulsion fracture

Introduction to finger avulsion fracture Muscle contractility is dependent on the contractile properties of the muscle itself and the starting and ending points of the muscle's cross-articular growth (some protrusions and trochanteric bones are tendon attachment points). A person can cause muscle contraction during strenuous activity, and the protrusion of the bone connected to the tendon and part or all of the bone of the trochanter are separated. The X-ray film shows the avulsion fracture of the hand. basic knowledge The proportion of illness: 0.02% Susceptible people: no specific population Mode of infection: non-infectious Complications: swelling

Causes of avulsion fracture of the finger

A person can cause muscle contraction during strenuous activity, and the protrusion of the bone connected to the tendon and part or all of the bone of the trochanter are separated. As the ligaments are pulled, the bones of the ligament attachment are peeled off together with the ligaments, forming a fragment of bone, called an avulsive fracture. (Commonly speaking, the muscle tendon is too strong, under the action of external force, causing fracture of the attached bone, tearing down the whole piece or a small part of the bone fragments).

Prevention of avulsion fracture of the finger

Some patients can avoid fractures, which requires everyone to be safe in daily life and work. - Attention can reduce fractures at all times, children are unstable, easy to fall, especially in high places, education And optimistic about children, to avoid falls, teenagers play more, curiosity, parents and teachers should do a good job in education, do not climb the tree, young and middle-aged people should concentrate on work and cycling, pay attention to safety everywhere Old people's hands and feet are inconvenient to move, snow and rain and nights try not to go out. When going out, someone needs to support or hold a cane. When going out at night, there must be lighting tools. It is best not to ride a bicycle on the street, not to crowded public places.

Finger avulsion fracture complications Complications swelling

1. Swelling

Swelling occurred locally after trauma and peaked after 72 hours, after which the swelling gradually subsided. After swelling occurs, the affected limb should be raised, preferably above the plane of the heart, and appropriate ice should be given to promote swelling.

2, plaster compression

After the simple fracture is performed by the caster to fix the cast, the cast of the limb will gradually increase, and the plaster will be pressed, resulting in obvious swelling, bruising, numbness, etc. at the end of the limb such as fingers and toes. To avoid limb compression and necrosis.

3, joint stiffness

The affected limb was fixed for a long time, the vein and lymphatic drainage were not smooth, the fibrous exudation of the serous fluid and fibrin deposition in the joint cavity, fibrous adhesion occurred, and the soft tissue contracture around the joint caused the joint movement disorder. This is the most common complication of fractures and joint injuries. Timely disassembly and active functional exercise are effective ways to prevent and treat joint stiffness.

Finger avulsion fracture symptoms Common symptoms Severe pain, wrist swelling and palmar flexion... Simple fracture

The symptoms of avulsion fractures are similar to those of fractures, with the main points of pain and limited joint activity, followed by local swelling and tenderness. An avulsion fracture of the humeral condyle is a special type of 23 intra-articular fracture, often an avulsion fracture of the anterior cruciate ligament or posterior cruciate ligament at the attachment of the tibia. Improper treatment can lead to malformation and cause instability of the knee joint. The avulsion fracture of the humeral condyle was treated with traditional open reduction and internal fixation with wire. Although the internal fixation of the open reduction wire can effectively reduce and fix the fracture block, it has a long incision and a large trauma. The postoperative functional exercise is extremely painful and long, and the knee joint is prone to stiffness, and the operation of the intercondylar notch is inconvenient.

Examination of finger avulsion fracture

1, X-ray inspection

X-ray film examinations should be performed routinely for patients with fractures, which can show incomplete fractures, deep fractures, intra-articular fractures and small avulsion fractures that are difficult to detect clinically, even if they have clinically manifested as obvious fractures. X-ray film examination is also necessary to understand the type and specific conditions of the fracture, which is of guiding significance for treatment.

X-ray films should include positive and lateral slices, must include adjacent joints, and sometimes need to add X-ray films of oblique position, tangential position or corresponding part of the healthy side.

2, CT examination

CT examination can be performed for those with unclear fractures but who cannot be excluded, those with spinal fractures that may compress spinal nerve roots and complex fractures. Three-dimensional CT reconstruction can make fracture classification more intuitive and convenient, and it is very helpful for treatment options. It is currently used clinically.

3, MRI examination

Although the fracture line is not as good as the CT examination, it has unique advantages for the display of spinal nerve root and soft tissue injury, and has been widely used for the examination of spinal fractures.

Diagnosis and differentiation of finger avulsion fracture

According to its clinical manifestations and X-ray examination, the disease can be clearly diagnosed without identification, but it is necessary to pay attention to the clinical whether the fracture is a simple fracture or a pathological fracture caused by the patient's own disease. In the case of disease and skeletal abnormalities, a slight force can cause a fracture, which occurs more frequently in this case and requires strict observation and diagnosis.
