A swan neck deformity is a condition that affects the fingers or toes, causing them to bend unnaturally. A swan neck deformity is where the finger or thumb joint closest to the nail is bent upward and the middle joint is bent downward. This creates a curved appearance similar to a swan's neck.
The condition can be caused by a variety of factors, including arthritis, injuries like a finger dislocation or laceration, or a genetic predisposition.
The deformity can cause pain and difficulty with gripping objects.
Treatment for swan neck deformity typically involves a combination of hand therapy, splinting, and sometimes surgery. Hand therapy can help to improve range of motion and decrease pain while splinting can help to hold the affected joint in a more natural position. In some cases, surgery may be necessary to correct the deformity and restore proper function to the affected area.
Overall, early intervention is key to preventing long-term complications and improving quality of life for those with swan neck deformity.
REAL CASE EXAMPLE: Dan
Meet Dan. He suffered a stroke that affected both of his upper extremities, leaving him with a signficant loss of hand function. As seen here, his right hand had multiple fingers present with a swan neck deformity when he straightened his fingers. He stated the small finger caused him a lot of discomfort and led to him avoiding using the finger during daily activities. Due to a muscle imbalance, structures in the finger would pull the joints in different directions causing the finger to form a swan neck position which is very dysfunctional and can be painful.
A therapist from Upper Hand Therapy fabricated him a custom splint to correct this deformity. The splint puts the middle knuckle in a slight bent position- which corrects the muscle imbalance and restores proper anatomy.
Dan had tried prefabricated oval 8 splints in the past, however quickly took them off because they were not comfortable since they were not custom-made. Dan was very pleased with his custom splint and immediately reported less finger pain.
Another advantage of the custom splint is that it still allows Dan to make a full fist, and even made his grip strength stronger!
