F. Brunelli Ligamentoplasty as Treatment in Thumb Basal Joint Arthritis: Up to 9 Years Follow-up.

Thumb basal joint arthritis treatment with biological arthroplasty is a widely used procedure in hand surgery centers. The several described techniques are based on the use of different tendons of the wrist, implying frequently a tenoplasty around flexor carpi radialis or transosseous tunnels to stabilize the articulation. The authors have been using, for many years, the technique conceived by F.

Debris of carbon-fibers originated from a CFRP (pEEK) wrist-plate triggered a destruent synovitis in human.

Application of carbon-fiber-reinforced-polymer (CFRP) artifacts in humans has been promoted in Orthopedic and Trauma Surgery. Literature documents the biocompatibility of materials used, namely carbon fibers (CF) and poly-ether thermoplastics, like poly-ether-ether-ketone (PEEK). A properly designed and accurately implanted composite artifact should not expose its fibers during or after surgery: however this may happen.
