The distal fibula anatomic plate combined with hollow screw fixation for Danis-Weber B double ankle fractures / 中国组织工程研究

ABSTRACT

BACKGROUND:Ankle joint fracture is a common fracture in the clinic. Proportion of Danis-Weber B fracture was large. Anatomic reduction and suitable internal fixator of lateral mal eolus are the key for successful repair. OBJECTIVE:To analyze the anatomic reduction effect of anatomic plate combined with hol ow screw fixation for inner and outer side fracture of the ankle joint. METHODS:A total of 32 patients with Danis-Weber B ankle fracture, who were treated from March 2010 to October 2013, were retrospectively analyzed. Plate and screw were used for internal fixation of lateral mal eolus. Double thread compression screw was used for fixation of medial mal eolus. American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Scale and Kofoed Ankle Rating scale were utilized to assess ankle function. Visual Analogue Scale was applied to evaluate the improvement in the degree of pain after repair. Radiographic analysis was conducted within a fixed position on the line for biomechanical level after internal fixation. RESULTS AND CONCLUSION:Al patients were fol owed up for 6-24 months. Al cases had bony union. AOFAS score, Kofoed score and visual analogue scale were significantly better at 6 months post-treatment than pre-treatment (P<0.05). Radiographic results revealed good alignment and contraposition fol owing internal fixation. Only one patient suffered from infection, and others did not have any adverse reactions. These results indicate that anatomic plate and hol ow screw fixation for the treatment of the medial mal eolus and lateral mal eolus fractures of ankle joint can exert their characteristics and biomechanical advantage, so fracture reached anatomical reduction of the ankle.
