Preoperative patient preparation and management
plaster, fracture, pain
LOWER LIMB DEEP VEIN THROMBOSIS
Upon admission, the affected limb is treated with plaster fixation, anti-swelling measures, pain relief, and preventive measures against lower limb deep vein thrombosis. Preoperative examinations are conducted comprehensively. Prior to surgery, all patients underwent ankle joint X-ray imaging in both anterior–posterior and lateral views (using a Philips digital radiography system from the Netherlands), as well as CT scans of the affected ankle joint with three-dimensional reconstruction (using a Philips 256-slice helical CT scanner from the Netherlands, with a slice thickness of 0.6 mm). In the personalized plate group, fracture data were virtually simulated, and 3D models were printed to customize individualized plates. Surgery was postponed until the patient's soft tissue condition improved.
