Abstract
AIM: We present the results of scaphoid non-unions treated with open reduction, bone grafting and internal fixation with biodegradable implants on active heavy labour workers.
MATERIAL AND METHODS: Between 2002 to 2004, 20 patients with scaphoid non-unions were treated by open reduction, bone grafting and internal fixation using self-reinforced poly-L-lactic acid screws. The mean prospective follow-up was 24 months (range, 12–38 months). The mean age was 28 years (range, 18–42 years). All patients were male and heavy-labour workers.
The patients were assessed clinically (modified Mayo wrist score) and radiograhically. The grip and pinch strength were also studied.
RESULTS: We find 13 excellent results, good in 5 cases and poor in 2 cases. A Matti-Russe group patient was revised 6 months after the first intervention. Any fragment displacement, implant loosening or adverse reaction was found. Most of the patients (90%) return to the same work and the same level without complications.
CONCLUSION: Both groups are a good alternative for the scaphoid non-unions treatment. However, biodegradable implants disappears in the time, the removal are no necessary, facilitate the revision surgery, if necessary, and permitted MRI studies to evaluated the graft viability.
