Boutonniere deformity, also known as buttonhole deformity, is a condition characterized by the abnormal positioning of a finger resulting from damage to the extensor tendons. It typically affects the middle finger, though it can occur in any finger. The deformity arises due to a rupture or avulsion of the central slip, which is a portion of the extensor tendon that runs over the proximal interphalangeal (PIP) joint. This injury leads to the inability to extend the finger at the PIP joint, causing the finger to bend at this joint while the distal interphalangeal (DIP) joint remains hyperextended. As a result, the affected finger commonly presents with a distinctive appearance resembling a buttonhole. The most common cause of boutonniere deformity is trauma, particularly injuries where the finger is forcefully bent or struck, such as in sports or accidents. However, it can also be associated with rheumatoid arthritis, where chronic inflammation leads to the weakening of the tendon structures. In rheumatoid arthritis, the synovial lining of the joints becomes inflamed, and eventually, the tendons may be eroded, resulting in the characteristic deformity. In addition to direct trauma and inflammatory conditions, boutonniere deformity can also result from congenital conditions affecting tendon development or from certain systemic diseases that compromise tendon integrity. Diagnosis of boutonniere deformity typically involves a thorough physical examination, where a healthcare professional will assess the range of motion and the positioning of the finger. Imaging techniques, such as X-rays or ultrasound, may be employed to evaluate the underlying joint structures and to exclude additional injuries. Management of boutonniere deformity often involves a combination of conservative and surgical approaches. In the acute phase following trauma, immobilization of the finger through splinting is the first line of treatment; this typically lasts for several weeks to allow the tendons to heal. In cases where the deformity persists despite conservative treatment or occurs due to chronic conditions like rheumatoid arthritis, surgical intervention may be necessary. This can involve tendon reconstruction, repair of the central slip, or even joint stabilization techniques, depending on the severity of the deformity and the underlying cause. Rehabilitation following treatment is critical to restore function and range of motion in the affected finger. Strengthening exercises and hand therapy play an integral role in recovery, helping to mitigate stiffness and enhance functional capabilities. Therefore, while boutonniere deformity can pose significant challenges, appropriate management strategies can lead to functional improvement and quality of life enhancement for affected individuals. Understanding the mechanism behind this condition is essential for both prevention and effective treatment, making awareness vital for those participating in activities at risk for finger injuries.
