Abstract

Due to various limitations in the use of autologous bone and allogeneic bone in the repair of bone defects, the use of synthetic bone graft substitute has become a hot topic in orthopedic surgery and repair medicine. A total of 53 patients treated for trauma‑induced metacarpal bone defects were recruited. These patients were divided into the TiAl6V4 titanium alloy implantation group (group A) and the autologous bone graft group (group B). The symptoms of patients in the two groups were closely observed and followed up. The operation time, time to bone fusion, post‑surgical pain [visual analog scale (VAS) scores], hand function recovery [total active flexion scale (TAFS) scores] and complications were compared between the two groups. Following surgery, none of the patients had necrosis of fingers or bone non‑union. The recovery was rated as excellent and good in up to 91.6% of patients, indicating high clinical efficacy. Compared with the use of autologous bone grafting as the gold standard (group B), there was no significant difference in the excellent and good recovery rate based on TAFS scores at 16 weeks after surgery (91.7 vs. 89.7%, P>0.05), and there was also no significant difference in the incidence of post‑operative complications (33.3 vs. 41.3%, P>0.05). The operation time (82.08±6.64 min), time to bone fusion (7.75±1.73 weeks) and VAS scores at 3 days after surgery were all significantly lower in group A than in group B (P<0.05). The values of group B were 104.69±8.63 min, 9.17±2.78 weeks and [5(5, 6)], respectively. However, the hospitalization cost (22,657.8±1,595.4Ұ) was significantly higher than that in group B (14,808.2±2,291.3Ұ; P<0.05). In conclusion, the use of titanium alloy implantation may avoid new injury to the donor site, reduce the operation time and post‑operative pain and accelerate bone fusion. Therefore, this method is worthy of popularization for defective bone reconstruction and recovery in the clinic.
