Health TipsCause of Thumb Joint Subluxation

Cause of Thumb Joint Subluxation – A female factory worker presented to a physician with pain in her thumb at the base, which was exacerbated by use and twisting motions. The pain was intermittent and was causing difficulty with daily tasks. She was unsure whether the condition was arthritis, but her physical examination revealed swelling and tenderness at the base of her thumb, along with crepitus at the first carpometacarpal joint. She also produced discomfort with a “grind test.” A radiograph and MRI were ordered.

Evaluating Causes of Subluxation of the Thumb Joint

A recent study investigated the incidence of thumb CMC subluxation. Participants were asked to hold the hand with the forearm pronated at 20 degrees. The thumb was held vertically to the film to determine whether it was impacted in the dorsal flexor tendon. The extent of dorsal subluxation or translation was determined by the size of the volar lip fragment anchored to the abductor pollicis longus tendon.

To evaluate the underlying cause of thumb joint subluxation, radiology was used to evaluate the underlying structure. In addition to the arthritic changes, the researchers observed that the subluxation was not due to an external force or a soft tissue injury. The patient was evaluated using a standardized radiographic procedure called a marrow aspiration. This surgery is effective for most cases and is also very safe.

The procedure was done under local or regional anaesthesia. The dissection was performed by making two longitudinal incisions over the thumb metacarpal and dorsomedial CMC joint. The patients were 38 years old at the time of surgery and the mean age at the time of injury was 13 days. The injuries were located in the dominant hand in nine cases and in the non-dominant hand in three.

Surgical Procedures Are Performed to Stabilize the Joints

The complication of the dislocation is treated by surgically repairing the torn tissues and bone. The complication can lead to bruising and pain in the affected hand. Surgical repair is necessary in these cases. A splint or cast is usually needed for a thumb joint subluxation. The surgical procedure may be performed to stabilize the joint and prevent further damage to the joints. While this is rare, it can be painful.

In some cases, the ligaments of the thumb may be torn. The muscles surrounding the joint are responsible for ensuring proper function of the hand. After a dislocation occurs, the tissues of the joint will be damaged. The fingers may be displaced, or the joints will become loose. In addition, the muscles of the wrist and the lower extremities may be strained and can be painful. Therefore, surgical treatment is necessary.

In addition to surgery, patients often choose to treat Thumb Joint Subluxation using immobilisation. This option is effective when the symptoms are not life-threatening. In other cases, the patient’s condition improves on its own and does not require any therapy. If surgical treatment is the only option, the patient can simply live with the pain until the condition improves. Alternatively, many patients will continue to live with the symptoms and modify their lifestyle.

Common Treatments for Thumb Joint Subluxation

The most common treatment for Thumb Joint Subluxation is surgery. The patient’s pain, swelling, and dislocation can be caused by torn ligaments in the joint. The joint will be treated with surgery. The patient may require a cast or a splint for several weeks. The thumb will be sore, but this will go away after the injury is healed. The patient can gradually return to normal activity.

Although the symptoms of Thumb Joint Subluxation vary in different patients, the diagnosis is generally unrelenting and may not require any invasive procedures. The patient’s condition should be diagnosed and treated as soon as possible. If the injury is severe, the patient should undergo immediate surgery. The surgeon should assess the severity of the problem and advise the patient. The X-ray should be interpreted by the patient’s doctor.

In the majority of cases, the patient will experience pain, bruising, and swelling. The doctor may recommend a cast or splint to protect the joint during the healing process. This procedure is also effective in preventing the occurrence of further complications. However, the surgeon should carefully examine the patient’s thumb for a fractured bone. An initial diagnosis of a Thumb Joint Subluxation is not an indication for surgery.
