Abstract

Curative effect and prognosis of 3D printing titanium alloy trabecular cup and pad in revision of acetabular defect of hip joint were investigated. Forty‑two patients who underwent acetabular revision in the Second Affiliated Hospital of Luohe Medical College were divided into observation and control groups according to different methods of acetabular revision and revision materials. 3D printed titanium alloy trabecular cups and pads were used in the observation group, and non‑3D printed titanium trabecular cups and pads were used in the control group. Preoperative and postoperative pain visual analog scale (VAS score), hip Harris scores and quality of life Health Survey Scale (SF‑36) scores were compared between the groups. At 3, 6 and 12 months after operation, Harris score and SF‑36 score of the observation group were significantly higher than those of the control group, and VAS score was significantly lower than that of the control group (P<0.05). Stability and bone ingrowth of prosthesis in the observation group were better than those in the control group. Revision of the hip prosthesis with 3D printed titanium trabecular metal cups and pads resulted in satisfactory outcomes. Short‑term prognosis is satisfactory but the long‑term prognosis remains to be further investigated.
