Symptoms of Kienbock Disease

Kienbock Disease, also known as avascular necrosis of the lunate, is a condition that affects the wrist joint. It occurs when the blood supply to the lunate bone in the wrist is disrupted, leading to its gradual deterioration. This condition primarily affects young adults, typically between the ages of 20 and 40, and is more common in men than women.

The symptoms of Kienbock Disease can vary depending on the stage of the condition and the severity of the damage to the lunate bone. Initially, individuals may experience mild discomfort or pain in the wrist, which is often dismissed as a minor injury or strain. However, as the disease progresses, the symptoms become more pronounced and can significantly impact daily activities.

One of the key symptoms of Kienbock Disease is wrist pain. The pain may be localized to the area around the lunate bone or may radiate to the surrounding areas of the wrist. The pain is typically aggravated by activities that involve gripping, twisting, or bearing weight on the affected wrist. Over time, the pain may become constant and more intense, even at rest.

Swelling and stiffness in the wrist joint are also common symptoms of Kienbock Disease. The affected wrist may appear swollen, and there may be a noticeable decrease in the range of motion. Individuals may find it difficult to fully flex or extend their wrist, and there may be a sensation of tightness or stiffness in the joint.

In some cases, weakness and instability in the wrist may be observed. The affected hand may feel weaker, making it challenging to perform tasks that require grip strength or fine motor skills. Instability in the wrist joint can also lead to a sense of the wrist "giving way" or feeling unstable during certain movements.

As Kienbock Disease progresses, decreased grip strength may become more apparent. Individuals may find it increasingly difficult to grasp objects firmly or maintain a strong grip. This can impact daily activities such as writing, typing, or lifting objects.

In advanced stages of the disease, limited mobility and deformity of the wrist joint may occur. The lunate bone may collapse or become fragmented, leading to changes in the alignment of the wrist bones. This can result in a noticeable deformity, such as a shortened or rotated wrist.

If you are experiencing persistent wrist pain, swelling, or any of the aforementioned symptoms, it is important to consult a healthcare professional for an accurate diagnosis. Early detection and appropriate treatment can help manage the symptoms and potentially slow down the progression of Kienbock Disease.
