1, regular review X-ray: fracture site varies, the time of regular review varies, usually once a month, but some patients need to advance early after surgery, there may be 3 weeks or every 2 weeks review. 2, the combination of active and passive functional exercise in the early postoperative period: fracture patients after effective fixation of the early joint without weight-bearing functional exercise generally started 3-7 days after surgery, early functional exercise is conducive to the prevention of muscle atrophy and joint ankylosis, to promote functional recovery. 3, the affected limb can not hold weight or weight-bearing: early postoperative fracture bone has not formed a stable structure, early weight-bearing or weight-bearing training can easily lead to internal fixation fracture. Patients should, under the guidance of doctors, perform partial weight-bearing to full weight-bearing walking of the lower limb and partial weight-bearing to full weight-bearing exercises of the upper limb at an appropriate time. 4.Effective external cast fixation: If the cast is loose or broken, the cast needs to be re-fixed, and the cast fixation of adult joint usually does not exceed 6 weeks.
