Swan Neck Deformity: Causes, Symptoms, and Treatment
Swan Neck Deformity is a condition characterized by an abnormal bending of the finger joints, resembling the shape of a swan’s neck. This condition primarily affects the fingers, particularly the middle and ring fingers, causing them to hyperextend at the proximal interphalangeal (PIP) joint while flexing at the distal interphalangeal (DIP) joint. This results in a noticeable curve in the affected fingers, making it difficult to fully straighten or extend them.
Swan Neck Deformity can be caused by various factors such as rheumatoid arthritis, trauma, or congenital abnormalities. It can lead to functional impairments, making simple tasks like gripping objects or typing challenging. Additionally, the abnormal joint alignment can cause pain, swelling, and stiffness in the affected fingers.
Treatment for Swan Neck Deformity may involve a combination of non-surgical interventions, such as splinting or hand exercises, to improve finger positioning and functionality. In severe cases, surgical options may be considered to correct the deformity and restore hand function. Early diagnosis and intervention are crucial in managing Swan Neck Deformity and preventing further complications.
