Abstract：Objective: To explore the curative effect of dislocation opening bone grafting in head and neck on osteonecrosis of the femoral head (ONFH) during collapse and follow-up imaging results. Methods: 86 patients confirmed with ONFH during collapse who were admitted to the hospital from April 2015 to April 2017 were enrolled. They were randomly divided into control group and observation group by simple random grouping method 43 cases in each group. The observation group was treated with external dislocation opening bone grafting in head and neck, while control group was treated with core decompression bone grafting. The operation time, intraoperative blood loss, postoperative drainage volume, first leaving bed time and hospitalization time were recorded. Before surgery, at 3 months and 1 year after surgery, VAS and HHS scores were performed to evaluate hip function. At 1 year after surgery, clinical curative effect and imaging curative effect of patients were evaluated by HHS scoring standard and ARCO staging. The complications and occurrence of postoperative hip arthroplasty were recorded. Results: There was no significant difference in the good rate of clinical curative effect and imaging curative effect between observation group and control group (86.05% vs 72.09%; 81.04% vs 65.12%) (P>0.05). The first leaving bed time and hospitalization time in observation group were significantly shorter (P<0.05). At 3 months and 1 year after surgery, VAS score of observation group were significantly lower than those of control group (P<0.05), and HSS score were significantly higher than those of control group (P<0.05). There was no significant difference in complications or incidence of postoperative hip arthroplasty between the two groups (P>0.05). Conclusion: Dislocation opening bone grafting in head and neck can improve clinical curative effect and imaging curative effect of ONFH patients.
