- Abstract: Objective To explore the application of 3D printing technology in hip replacement. Methods The clinical data of 130 patients who underwent hip replacement were retrospectively analyzed. According to different surgical approaches, the patients were divided into traditional surgery group (n=70) and 3D printing group (n=60). The evaluation indexes of surgery, imaging indexes, scores of hip function before and after surgery, force line of lower limbs and incidence of complications were compared between two groups. Results The intraoperative blood loss in 3D printing group was less than that in traditional surgery group, and moreover, the operation time, leaving bed time and hospitalization time were shorter than those in traditional surgery group (P<0.05). The deviations of acetabular cup abduction angle and anteversion angle as well as the vertical and horizontal distance deviations of hip rotation center in 3D printing group were smaller than those in traditional surgery group (P<0.05). At 3 months after surgery, compared with traditional surgery group, 3D printing group had a higher Harris score of hip function (P<0.05) and a lower force line of lower limbs (P<0.05) and no significant difference was found in the incidence of complications between two groups (P>0.05). Conclusion The effects of 3D printing technology and traditional surgery are comparable on assisting hip replacement. However, the former can reduce intraoperative blood loss, shorten operation time, leaving bed time and hospitalization time, improve stability of postoperative hip joint, and improve force line of lower limbs.
