Abstract:
Objective To investigate the effectiveness of axial load shared in guiding the axial motorization of external fixators to promote fracture healing after the surgery of tibia and fibula diaphyseal fracture. Methods A total of 100 patients with tibia and fibula diaphyseal fractures treated with external fixator were randomly divided into observation group (n=50) and control group (n=50). The patients in observation group were treated with the external fixation axia dynamization under the guidance of axial load sharing ratio, while the patients in control group with no act. The follow-up comparison was compared between the two groups. Results All patients were followed up for 4 to 12 months with an average of 6.5 months. During the treatment period, no complications such as fracture, loosening, and re-fracture of the external fixation needles occurred. In the observation group, the axial load of the patient with bone removal was observed. With a sharing ratio of < 5%, the X-ray showed that the broken ends of the fractures had a continuous poroma pass. After dismantling the external fixation connecting rods, they shifted. The original values were restored by axial compression and then motorized, and they have now healed. In the observation group, except for one patient with bone removal, the rest of the 49 patients had an external fixation time of (24.4±4.7) weeks, and the clinical healing time of the fracture was (22.4±4.7) weeks. In the control group, 50 patients had a fixed external fixation time of (29.3±5.6) weeks, and clinical healing time of fracture was (27.3±5.6) weeks (P<0.05). Conclusion The axial load sharing ratio of external fixator guides axial motorization after external fixation of tibia and fibula diaphyseal fracture can accelerate fracture healing, but it is not suitable for bone removal of patients with hardened osteotomy end.
