Abstract:
ABATRACT Objective:To observe the incidence,causes and deviation angle of axial offset in patients with fracture un-united treated by Ilizarov bone transport technology. Methods:From January 2007 to December 2012,10 patients with fracture ununited were treated by Ilizarov bone transport including 8 males and 2 females with an average age of (30.3±10.6) years old ranging from 18 to 49 years old. The segment of bone defect involved upper tibial in 2 cases ,medial tibia in 2 cases,lower tibial in 5 cases,upper femoral in 1 case. For Paley type of bone defect,6 cases were type B1,4 cases were B3. The incidence and deviation angle of axial offset after Ilizarov bone transport technology were observed and evaluated on bone result by Paley as-sessment. Results:All patients were followed up from 19 to 32 months with an average of (22.0±5.6) months. Three cases were natural healed at fracture ends,the other 7 cases were healed after bone graft. The time of external fixator was 16 to 28 months. At the last follow up,there were 3 cases occurred coronal angulation of angle 5° to 11 ° with an average of (8.7±3.2)°. Sagittal angulation was in 4 cases,angle 6° to 9° with an average of (8.5±2.1)°. There were 4 cases occurred axial offset. In the last fol-low up,according to Paley evaluation criteria,osseous results were excellent in 7 cases,good in 3 cases;functional results were excellent in 6 cases,good in 4 cases. Conclusion:Axial deviation after the Ilizarov bone transport treatment is relatively com-mon,which will result in delayed healing of bone and poor limb alignment. In order to improve the bone healing ,corresponding measurements should be taken to avoid or reduce the incidence of axial deviation during and after the operation.
