Self-reinforced bioabsorbable miniplates for skeletal fixation in complex hand injury: three case reports.
We report our preliminary experience with 3 cases in which internal fixation with a self-reinforced poly-l/dl-lactide 70/30 miniplate and 1.5-mm or 2.0-mm screws were used to stabilize an open metacarpal fracture, a metacarpophalangeal arthrodesis in a thumb replantation, and an interposed bone graft for reconstruction of a thumb. Clinical and radiologic follow-up evaluation lasted for 12 to 20 months. Bone healing was uneventful in all 3 cases with no displacement or delayed union. The implants were biocompatible with no clinically manifested foreign body reaction. Because of the self-reinforcing manufacturing technique the plates have metal-like mechanical and handling properties. Complete late resorption makes self-reinforced poly-l/dl-lactide 70/30 miniplating systems an attractive alternative to metallic implants for skeletal stabilization of small bones of the hand.
