The application of PLA/HAP absorbable screw-plate fixation in the treatment of metacarpal fractures

Abstract

Objective To evaluate the application of PLA/HAP screw-plate in the treatment of metacarpal fractures. Methods Twenty-four metacarpal fractures in 22 patients were treated with PLA/HAP absorbable screw-plate fixation. Postoperatively flexion and extension movement of the affected finger, grip strength and sensation were evaluated. X-ray examination was carried out to check bone healing. Results All the patients were follow-up for 4 to 12 months with an average of 6.2 months. All the 24 fractures healed with no fracture displacement, loss of reduction, infection, nonunion or other complications. Two cases suffered delayed union. Average fracture healing time was 6.1 weeks. TAF system was adopted to measure and evaluate finger flexion and extension functional recovery. At one month postoperatively the results were graded as good in 14 fractures, fair in 7 fractures and poor in 3 fractures, the overall satisfactory rate being 87.5%. At three months postoperatively the excellent and good rate achieved 100%. Conclusion Metacarpal fractures can be effectively treated with PLA/HAP absorbable screw-plate fixation which is a simple procedure that causes no complications.
