Boutonniere Deformity: Causes, Symptoms, and Treatment Options
Boutonniere deformity is a condition affecting the finger joints, specifically the middle joint (PIP) of the finger. It is characterized by a bent or flexed middle joint and a hyperextended outer joint (DIP). This deformity occurs when the central tendon, responsible for straightening the finger, is damaged or disrupted.
Common causes of boutonniere deformity include trauma, such as a forceful blow to the finger, or inflammatory conditions like rheumatoid arthritis. Symptoms may include pain, stiffness, and limited range of motion in the affected finger. Additionally, the finger may exhibit a characteristic appearance with a bent middle joint and a straight or hyperextended outer joint.
Early diagnosis and treatment are crucial to prevent further joint damage and functional impairment. Non-surgical interventions, such as splinting and hand therapy, may be recommended to restore finger function. In severe cases, surgical intervention may be necessary to repair the damaged tendon and realign the finger joints.
If you suspect you have boutonniere deformity, it is important to seek medical attention for an accurate diagnosis and appropriate treatment options.
