  1. Criteria for bone results:
  2. Excellent: union, no infection, deformity < 7°, limb length discrepancy (LLD) < 2.5 cm
  3. Good: union + any two of the following: absence of infection, deformity < 7°, LLD < 2.5 cm
  4. Fair: union + any one of the following: absence of infection, deformity < 7°, LLD < 2.5 cm
  5. Poor: nonunion/refracture/union + infection + deformity > 7°+ LLD > 2.5 cm
  6. Criteria for functional results:
  7. Excellent: active, no limp, minimum stiffness (loss of < 15° knee extension/ < 15° ankle dorsiflexion) no reflex sympathetic dystrophy (RSD), insignificant pain
  8. Good: active, with one or two of the following: limb, stiffness, RSD, significant pain
  9. Fair: active, with three or all of the following: limb, stiffness, RSD, significant pain
  10. Poor: inactive (unemployment or inability to return to daily activities because of injury)
  11. Failure: amputation
  12. We used the average number of reoperations per patient (times/case) as the evaluation index in the two groups. One reoperation may be due to a single complication or multiple complications; on the other hand, some complications may require two or more reoperations
