In patients with tibial fractures the bone scab is not very strong at 60 days post-injury. At this point the patient may have just returned to clinical healing and is performing functional exercises under non-weight bearing conditions. Because of the poor blood supply to the tibia and the severity of the injury, the recovery time for a tibia fracture is somewhat longer than for a normal fracture. After proper treatment, these patients may be able to achieve clinical healing in about 6 to 8 weeks. At this point, the bone scab in the affected area is often only strong enough to bear light weight. For example, the patient may be able to lift the affected limb out of the external fixation device and straighten it in bed. Some patients who have recovered well may be able to do some weight-bearing activities on the floor with the protection of crutches. It is recommended that patients in the above time period should not carry out related activities without authorization, but return to the orthopaedic department for follow-up in a timely manner, and carry out the corresponding activities or functional exercises under the guidance of the doctor, so as to avoid causing secondary injury to the fracture site.
