Αιτίες

Wrist sprains typically occur when a person falls and lands on an outstretched hand, causing the wrist to bend backward and stress the ligaments.

Σημεία και Συμπτώματα

After a sprain, the wrist usually swells and bruises, and movement becomes painful. The injury often results in limited mobility and discomfort during everyday activities.

Diagnosis

The doctor will start with a physical examination to pinpoint the area of pain and assess wrist movement. X-rays are used to rule out fractures or dislocations, and sometimes an MRI is ordered for a detailed view of the ligament damage.

Acute treatment

Initial treatment for a wrist sprain may involve immobilizing the wrist with a splint or cast. In some cases, surgery is necessary. Surgical options include arthroscopic procedures—performed through small incisions with a camera and specialized instruments—or open surgery to repair the damaged ligament using pins, screws, or other devices. Postoperative care typically involves immobilization for several weeks.

Chronic injuries

For injuries that have persisted for months or years, treatment depends on the extent of damage. If there is minimal cartilage damage, ligament reconstruction may be considered. However, if moderate to severe cartilage damage (arthritis) is present, symptoms such as pain, stiffness, and swelling may continue. Initially, chronic injuries may be managed with splinting, non-steroidal anti-inflammatory drugs (NSAIDs), and cortisone injections, with surgery as a later option. Surgical approaches might include partial wrist fusion, proximal row carpectomy (removal of arthritic bones), wrist replacement, or complete wrist fusion.

Associated injuries

Occasionally, fractures occur along with a sprain, requiring additional procedures to repair the bone with metal pins, screws, or plates. Cartilage damage may also accompany the sprain, even if it isn’t visible on x-rays.

Future treatments

Ongoing research aims to develop better treatments for wrist sprains, focusing on stronger and more precise ligament reconstruction techniques. These innovations may use tissues from the local area or grafts from other parts of the hand or foot.

Prognosis

Even with optimal treatment, some individuals may experience long-term pain, stiffness, and swelling. Due to the wrist’s complex arrangement of bones, cartilage, and ligaments, injuries can disrupt its finely tuned balance and lead to lasting functional issues.

Βασικά σημεία

• A wrist sprain is a ligament injury often caused by falling on an outstretched hand.

• It typically results in swelling, bruising, and pain, with diagnosis involving physical exams and imaging studies.

• Treatment ranges from immobilization and non-surgical care to various surgical options, with some long-term issues possible despite optimal care.
