Strong and nearly invisible splints stabilize and align the DIP or PIP joint to enhance hand function. Molded from 1/16" (1.6mm) translucent plastic without seams. Can be used to correct lateral deviation, swan-neck deformity and flexible boutonniere deformity, support mallet finger injury, and help prevent trigger finger. Two ring splints can be used to provide full immobilization at the PIP or DIP for rest and control. Each Oval-8® splint fits a full size and, when rotated 180°, an additional half size, to accommodate fluctuations in edema and temperature that can affect finger size. Latex free.
