Nanomaterial has significantly taken a place in orthopedic surgery, however, the efficacy of using n-HA\/PA66\n is yet to be established. In this regard, this study evaluated various sagittal parameters (such as imaging measurement) and clinical efficacy in postoperative patients, whom underwent cervical reconstruction surgery due to cervical spondylosis myelopathy (CSM). In this study, total 62 CSM\n cases were enrolled between October 2016 to March 2020, and were hospitalized for cervical reconstruction surgery. 31 cases were grafted with titanium mesh and 31 cases were grafted with n-HA\/P66. The sagittal parameters such as cervical spine lateral radiographs (C<jats:sub>0\u20132<\/jats:sub>Coob,\n C<jats:sub>2\u20137<\/jats:sub>Coob, T1S, CSVA, and TIA) were taken before operation, after operation (within 1 week), 3, 6, and 9 months after operation. In order to evaluate the clinical efficacy, we used JOA scores before, after, 3 months, 6 months and 9 months after operation. Results showed that\n JOA scores after the re-examination in the two groups (titanium and n-HA\/P66) were significantly higher than before the operation, suggesting a well postoperative functional recovery after surgery in both groups; however, there was no significant difference in JOA score and JOA improvement\n index between the two groups. In regard of angles measurement (C<jats:sub>0\u20132<\/jats:sub>Cobb, C<jats:sub>2\u20137<\/jats:sub>Cobb, T1S, CSVA, and TIA), we observed no significant difference between these two groups before and after the operation. In addition, we showed that C<jats:sub>0\u20132<\/jats:sub>Cobb and\n C<jats:sub>2\u20137<\/jats:sub>Cobb angle had a significant positive correlation; and C<jats:sub>0\u20132<\/jats:sub>Cobb angle is positively correlated with T1S, and negatively correlated with CSVA. Both titanium mesh and n-HA\/PA66 can be well improved and maintained within 9 months after surgery with clinical\n efficacy, however, using n-HA\/PA66 might have more benefits.<\/jats:p>","DOI":"10.1166\/jbn.2022.3316","type":"journal-article","created":{"date-parts":[[2022,7,20]],"date-time":"2022-07-20T00:42:42Z","timestamp":1658277762000},"page":"1187-1195","source":"Crossref","is-referenced-by-count":2,"title":["Investigation
