ABSTRACT

BACKGROUND: Many researchers at home and abroad think that interlocking intramedul ary nails may be more suitable for comminuted fractures of the tibia with severe soft tissue injury. Plate fixation is more advantageous for distal tibial fractures. OBJECTIVE: To compare the effects of multifunctional locking intramedul ary nail and locking plate in treatment of extraarticular proximal tibial fractures. METHODS: 156 patients with extraarticular proximal tibial fractures were included and divided into intramedul ary nail group (n=78) and the locking plate group (n=78) according to repair method. Curative effects and healing time were compared between the two groups. At 3 months after treatment, Johner-Wruh tibial fracture scores were used to assess the repair effect in both groups. In addition, operation time, blood loss, healing time and complications were compared between the two groups.RESULTS AND CONCLUSION: Mean healing time was 9.3 months in the locking plate group and 9.2 months in the intramedul ary nail group. At 3 months after treatment, the repair effect was significantly better in the intramedul ary nail group than in the locking plate group (P < 0.05). Blood loss and time were less in the intramedul ary nail group than in the locking plate group (P < 0.05), and surgical difficulty was high. At 3 months after treatment, the incidence rates of tibia eversion/inversion, neurovascular injury and nonunion/infection were significantly lower in the intramedul ary nail group than in the locking plate group (P < 0.05). These findings confirmed that the multifunctional locking intramedul ary nailing for extraarticular proximal tibial fractures obtained reliable efficacy, exact effect, reduced blood loss and low incidence of complications. Thus, it is better than locking plate.
