Detailed explanation-1: -Swan neck deformity is usually caused by weakness or tearing of the ligament in the middle joint. In some cases, the tendon is torn and weakened. Over time, it gets harder for your tendons to straighten the joint. This causes the joint to bend abnormally.
Detailed explanation-2: -A swan-neck or boutonniere deformity occurs in approximately half of patients with rheumatoid arthritis. The cause of boutonniere deformity is chronic synovitis of the proximal interphalangeal joint.
Detailed explanation-3: -The usual cause of a swan neck deformity is weakness or tearing of a ligament on the palm side of the middle joint of the finger. Sometimes it is caused by tearing of the tendon that flexes the middle joint. In other cases, injury of the tendon that straightens the end joint is the cause.
