SIX-AXIS PARALLEL BONE EXTERNAL FIXATION DEVICE-BASED FRACTURE HEALING EVALUATION METHOD

摘要

The invention discloses the fracture recovering evaluation methods based on six axis parallel connection bone external fixation devices, are broadly divided into following steps: adding sensor to each branch of existing six axis parallel connection bone external fixation device, and fracture is resetted and fixed using modified device；Using marker, pass through spatial position and the posture of medicine CT scanning recognition fracture bone block and bone external fixation device；According to clinical general rehabilitation stage division method, rehabilitation course is divided into the first period and the second period: when patient was in for the first period, measuring and analyze the mechanics situation of fracture site, optionally finely tuned bone external fixation device and and guide Rehabilitation training；When patient was in for the second period, the quantizating index of fracture recovering is calculated, suitable opportunity is selected to remove bone external fixation device.This method is suitable for all kinds of commercially available six axis parallel connection bone external fixation devices, economical and convenience；This method carries out the quantitatively evaluating of fracture recovering, good reliability using the method for energy spectrometer.
