Indicated for PIP injuries such as sprains and strains and for repair of partial collateral ligament tears. Can also be used post-operatively for PIP protection. Constructed of low-gauge padded aluminium that can be modified using pliers. Comes complete with straps. To determine size, measure circumference of PIP joint.
