What is Chronic Wrist Ligament Instability?

The wrist is the most complex joint of the body, so it is naturally prone to more issues than any other area. It is made up of a platform of two bones on the end of the radial and ulnar bones, linked to a collection of ligaments which are responsible for all wrist movements, and are heavily linked to most movements of the hands. Problems can arise due to the wear and tear of these ligaments over time, leading to an increased risk of chronic instability developing as the person ages.

What is Chronic Wrist Ligament Instability?

Chronic Wrist Ligament Instability, also known simply as carpal instability, occurs when the small bones in the wrist become displaced from their original position, eventually leading to a decrease in overall joint function. All joints require ligaments in order to maintain stability when loaded by the natural pressures of use, particularly when the joint is used heavily.

For the wrist, this stability is especially important due to the complexity of the joint and its inherently large range of movement. When the ligaments begin to break down and fail, it leads to the bones of the joint beginning to move abnormally relative to one another, leading to a general feeling of instability that can be difficult to overcome.

Types of Chronic Wrist Ligament Instability

Chronic Wrist Ligament Instability is a far-reaching term that applies to the onset, or combination, of a number of different conditions. To help with narrowing down a diagnosis, there are four major types of carpal diagnosis that are typically classified, each with different effects and treatments. These are usually diagnosed through radiography, and include:

• Dorsiflexed Intercalated Segment Instability (DISI): The lunate (ulnar-sided carpal bone) appears as an intercalated segment between the distal row and an abnormally extended forearm
• Volarflexed Intercalated Segment Instability (VISI): The lunate appears to be flexed to an abnormal level
• Ulnar Translocation (UT): The proximal row of ligaments shows an ulnar deviation to the radius (thumb-sided carpal bone)
• Dorsal Translocation (DT): The carpus is subluxed (partially dislocated) in a dorsal direction, secondary to an already-present fracture

What Causes Chronic Wrist Ligament Instability?

Once the ligaments of the wrist are compromised, the abnormal movement of the bones can cause an excess of wear and tear in the area. Particularly, the articular cartilage lining the bones will become damaged, which can lead to a wide range of symptoms and conditions, including arthritis, and a general feeling of pain and instability.  Instability can also occur due to a sudden tear of the carpal ligaments, or when the bones are fractured, or heavily affected by arthritis.

Symptoms of Chronic Wrist Ligament Instability

Since Chronic Wrist Ligament Instability is such a widely defined condition that affects such a large network of ligaments and cartilage, the symptoms are fairly general in scope. It can cause ongoing pain due to abnormal stresses on the remaining ligaments, as well as a loss of range of motion and a feeling of stiffness. The most common symptoms include:

• Pain throughout the wrist
• Snapping or clicking noise during movement
• Difficulty moving the hand from side to side
• A feeling of weakness in the wrist
• Decreased range of motion and articulation
• Development of arthritic symptoms

Treatment of Chronic Wrist Ligament Instability

Treatments of Chronic Wrist Ligament Instability are selected based on the severity and location of your condition, which should be diagnosed by your physician through radiology. The first step of treatment is to modify activity, and temporarily stop any movements that cause excess pain. After that, anti-inflammatory pain medications should be used, which can be applied topically or taken orally. If your physician deems the severity of your condition as insufficient for surgery, a wrist splint can be used to prevent any damaging movements, and limit the range of motion in the area while it heals.
