Abstract:

BACKGROUND: The number, displacement, joint surface of ankle joint fracture and fracture fragments of joint space are very complex under different external forces, which are not well shown by X-ray plain film. Although axial two-dimensional CT has high resolution and no-overlapping image, there is difficulty in accurate and complete evaluation of fracture fragments.
OBJECTIVE: To investigate the clinical value of spiral CT three-dimensional reconstruction in classification diagnosis and treatment of ankle joint fracture.
METHODS: A total of 36 patients with ankle joint fracture received spiral CT three-dimensional reconstruction. The Danis-Weber classification of ankle joint fracture was diagnosed. According to the results, project of internal fixation was formulated, and the excellent operation way was selected. Curative effect was evaluated according to Barid-Jackson standard.
RESULTS AND CONCLUSION: Results of spiral CT three-dimensional reconstruction showed there were 22 type B patients (61%) and 14 type C patients (39%) in 36 patients with ankle joint fracture. The therapeutic effects showed there were 19 excellent patients (53%), 13 good (36%) and 4 fair (11%) in 36 patients with an excellent and good rate of 89%. Spiral CT three-dimensional reconstruction can really reflect the lesions of ankle joint fracture. It has clinical significance in classification diagnosis and treatment of ankle joint fracture.
