What Are the Most Common Causes of a Sprained Wrist?

Wrist sprains Wrist sprains are caused by external forces. There are different opinions on the mechanism of wrist injury, but most scholars believe that it is caused by excessive back extension of the wrist to withstand violence. When the wrist joint is in the dorsiflexion and ulnar deflection position, plus excessive external force, the movement of the wrist joint exceeds the normal range, which will cause corresponding tissue ligament, fascia and other tissue damage.

Wrist sprain

When a person falls to reach the ground with their hands, the wrist joint is the joint that first bears and transmits external force to the proximal end of the limb. Therefore, the wrist joint is susceptible to damage. If improper treatment is performed after the injury, the relationship between the wrist and bone can be changed, which is called the wrist joint instability.

Bone and joint MRI examination:

Bone and joint MRI examination is to use MRI to scan the bones and joints to observe the condition of the bone and diagnose the related diseases. Suitable for patients with bone and joint disease.

Differential diagnosis of wrist joint sprain:

1. Hematoma and limited mobility in the wrist joint: Radial and ulnar styloid fractures are mainly manifested as local swelling, pain, tenderness, and bone fricatives. Subcutaneous stasis, severe hemoptysis in the wrist, limited movement of the wrist.

2. Pain on the radial side of the wrist joint: The degenerative changes of the finger joints are manifested in the Heberdens nodules of the distal interphalangeal joints, which occur in the middle and index fingers. Bouchards nodules of the proximal interphalangeal joints rarely occur and are often mistaken. It is thought that rheumatoid nodules, degenerative changes of the first metacarpophalangeal joint can cause pain at the radial side of the wrist joint, and other metacarpophalangeal joints are rarely involved.

3. Radical pain occurs when the wrist joint is deflected to the ulnar side: The ulnar deviation test of the radial styloid fracture is positive, that is, acute pain occurs when the wrist joint is deflected to the ulnar side.

Prevention of wrist joint sprains:

Depending on the area of the wrist injury, one of the following methods can be used

1. Poke method. The patient is sitting, the injured wrist is extended, the palms are facing down, the doctor is standing on the injured side, holding the lower end of the forearm with one hand, and holding the first metacarpal root (Yangxi point) with his thumb. Hold the first metacarpal and thumb with your other hand, shake it from the outside to the inside ring and shake it 6 or 7 times before pulling it out. While maintaining the strength of the pulling out, stretch the back of your thumb and simultaneously press the thumb of your wrist down. .

2. Poke method. The patient is sitting with the injured wrist extended and the palms facing up. The doctor stands in front of the patient, holds the injured wrist, and fastens the injured part (Taiyuan acupoint) with the middle finger. Holds the thumb and the first metacarpal with the other hand, and rotates from the outside to the inside. Shake 6 or 7 times, and then stretch, while flexing the wrist while maintaining the strength of the stretch, while holding the wrist in your hand, press down.

3. Reinforcement method. The patient is sitting with his injured wrist extended and his palms facing down. The doctor stands in front of the patient, holds the injured wrist with one hand, and clasps the injured part (Yanggu acupoint) with the middle finger, and holds the sign, middle, ring, and little finger from the side of the little finger and shakes from the inside to the outside or from the outside to the inside. 6 or 7 times, then stretch. While maintaining the extension strength, flex the wrist to the radial side, and then quickly flex to the ulnar side, while holding the middle of the hand holding the wrist and press the radial side.

4. Method of inflection. The patient is sitting. The injured wrist is extended with the palms facing upwards. The doctor stands in front of the patient. Hold the injured wrist with one hand, and hold the injured part (Shenmen acupoint) with your middle finger. Hold the Shih, middle, ring, and little finger from the side of the little finger, and shake it from the outside to the inside ring 6 or 7 times, and then pull out diagonally upward and then flex to the ulnar side, while holding the middle of the wrist hand down Poke.

5. Shunjin method. The patient is sitting with his injured wrist extended. With the tiger's mouth down, the doctor stood outside the injured wrist, holding the injured wrist with one hand from the back and holding the wound (Shenmen acupoint) with his thumb, holding the palm from the back with the other hand, shaking it around 6 or 7 times, Extend the side of your finger, then lift the injured arm upward (hand palm forward), hold the palm of your hand to flex your wrist, and hold the thumb of your wrist down to smooth the injured tendon.

With the palms down, the doctor stands in front of the patient, holding the injured wrist from the side of the little finger with one hand, and using the thumb to buckle the wound (Yangchi acupoint). Shake it 6 or 7 times, and then extend the wrist and palm flexion, then quickly do dorsiflexion, while pressing the thumb down.

7. Fingering. The patient is sitting, with the injured wrist extended, five fingers open, palms facing forward, the doctor standing in front of the patient, holding the injured wrist from one side of his thumb with his thumb clasped to the wound (Yangchi acupoint), and the other with five fingers hurting the patient The fingers are fastened with their fingers crossed, and shaken from the outside to the inside ring 6 or 7 times, then the wrist joint is flexed and extended, and then quickly dorsiflexed, while holding down the thumb of the injured wrist and poking down.

8. Take advantage of the tendon method. The patient is sitting with the injured wrist extended. The doctor stands in front of the patient and places the injured palm on the patient's chest. The doctor uses one hand to hold the injured palm from the side of the little finger, and the other holds the injured wrist from the thumb side. At the Daling Acupoint, the patient pushed the doctor's chest hard. The doctor quickly lifted the injured arm with the palm of his hand, and at the same time flexed the injured wrist with the thumb of the wrist down to do the tendon method.

Wrist sprain and contusion 9. Push method. For dorsal wrist hematoma. The assistant held the patient's elbow, the doctor held the patient's back, first resisted the extension, and then pushed the hematoma with the thumb. Before pushing, the pressure was applied to the middle of the hematoma, depending on which side the hematoma was moving, and then decided Push up or push down. When pushing, there was a sound of hematoma breaking under the fingertips, and the hematoma dissipated immediately.

10. The doctor holds each patient's 1 to 5 fingers one by one, and then shakes 1 to 5 fingers one by one under the pull-out extension and makes a shaking technique to relax the muscle spasm. ^[1]
