Abstract
OBJECTIVE: This study aimed to investigate the animal experimental and clinical results of the bone graft fusion of a posterolateral lumbar appendicular bone. METHODS: 1. Sixty rabbits were randomly divided into experimental and control groups. Posterolateral lumbar bone graft with the appendicular bone and iliac bones, respectively, was then performed on these two groups. A lumbar spine X-ray was performed on the postoperative 4(th), 8(th) and 16(th) weeks, and the gray value changes of the bone graft fusion area were measured to calculate fusion rates. Histology analysis was also performed to observe and count osteoblasts. 2. The appendicular bones of 106 patients who suffered from lumbar disorders were cut during lumbar surgery, and a posterolateral lumbar bone graft was performed. The postoperative follow-up used the Steffee criteria to evaluate clinical efficacy and the White criteria to evaluate fusion conditions. RESULTS: No significant difference was observed in the relative gray values of X-ray bone density, bone graft fusion rates, and osteoblast counts in the bone graft regions between the two groups (P > 0.05). The follow-up duration of the 106 patients were 4-8 years (6.12 years), the clinical efficacy rate was 85.85%, and the fusion rate was 83.02%. CONCLUSIONS: The animal experimental and clinical results of posterolateral lumbar bone graft fusion with autologous iliac and appendicular bones were similar.
