The PSB Thumb Brace supports the thumb when the thumb joint has become unstable as a result of straining of the joint ligament. The strap in the brace as it were compensates for the additional movement brought about by the damaged ligament. The brace offers joint protection, also against impact. The undamaged joints remain free and the straps can be adjusted in such a way that the thumb can function normally. The brace leaves the wrist entirely free and in no way restricts the wrist movement. The brace is perfectly suited for wearing during sport. Another advantage: the PSB Thumb Brace offers exceptional comfort and is easy for the wearer to apply.IndicationThe PSB Thumb Brace is used for the so-called skier"s thumb: residual instability (free movement) as a result of an injury to the inside of the thumb joint.
