RESUMO
BACKGROUND:Schatzker V, VI fracture often causes the injuries to cruciate ligament, col ateral ligaments and meniscus. Moreover, the col apse and shifting were severe. The locking plate on one side cannot support the weight or obtain satisfactory reduction. OBJECTIVE:To compare the effects and stability of the dual-incision double-plate fixation and knee midline incision locking plate fixation in the treatment of Schatzker V, VI tibial plateau fracture. METHODS:A total of 76 patients with Schatzker V, VI tibial plateau fracture were respectively treated with locking plate fixation (n=38) and dual-incision double-plate fixation (n=38). Fracture reduction and healing were assessed using anteroposterior and lateral radiographs. Varus angle and medial caster angle of tibial plateau received biomechanical measurement. RESULTS AND CONCLUSION:Hospital stay and postoperative load time were significantly less in the dual-incision double-plate fixation group than in the locking plate fixation group (P0.05). The number of complications, such as ankylosis, fracture delayed union, pin tract infection, delayed union, varus deformity, was significantly fewer in the dual-incision double-plate fixation group than in the locking plate fixation group (P0.05). Postoperative Rasmussen classification was significantly better in the dual-incision double-plate fixation group than in the locking plate fixation group (P<0.05). Experimental results indicated that the clinical efficacy of the dual-incision double-plate fixation is superior to that of the anterior cruciate midline incision locking plate fixation in the treatment of Schatzker V, VI type tibial plateau fractures. The dual-incision double-plate fixation has more biomechanical stability.
