SWAN NECK DEFORMITY
The most common causes of a Swan Neck deformity are Rheumatoid Arthritis (RA), a
ligament injury or an untreated Mallet or “Baseball” finger. A Swan Neck deformity is a
condition where the middle joint of your finger hyperextends or bends backwards and the
end joint, near the fingernail, flexes or bends downwards.
How Do I Wear the Oval-8?
Wear an Oval-8 Finger Splint to block the hyperextension at the middle joint of your finger
while still allowing your finger to bend for full hand movement.
The splint is worn around your middle knuckle with the oval portion
on top to prevent the joint of your finger from bending backwards (hyperextending)
and the band on the palm or inside of your finger.
