Objectives:
To explore the application of 3D printed navigation template technology in severe Hallux valgus surgery.
Methods:
Forty-eight patients with severe Hallux valgus were selected. There were 24 cases in the control group underwent hallux valgus osteotomy using traditional methods and fixed with fully threaded hollow screws during the surgery. There were 24 cases in the 3D group who underwent personalized osteotomy using 3D printing navigation template technology. Patients were followed up regularly for six months after surgery.
Results:
The surgery time of the 3D group was shorter than that of the control group, and the intraoperative bleeding was reduced (P<0.05). Compared with the preoperative data, the HVA and IMA significantly reduced immediately and 1, 3, and 6 months after surgery (P<0.05). The VAS scores decreased significantly, while the AOFAS and SF-36 scores increased (P<0.05). At three months and six months after surgery, the VAS score of the 3D group was lower than that of the control group, while the SF-36 score was higher (P<0.05). During the follow-up period, both groups had no recurrent cases or complications.
Conclusions:
The 3D printing navigation template technology improves patients' prognosis, functional recovery, and quality of life.
