Clinical Investigation of the Association of Opening Size with Sagittal Canal Diameter Based on Single-Door Cervical Laminoplasty
BACKGROUND Many clinical studies have assessed the association of laminoplasty opening size (LOS) with sagittal canal diameter (SCD) based on single-door cervical laminoplasty (SDCL). Nevertheless, the "worn-off" lamina extracted in SDCL was neglected in these reports. We aimed to develop...

Nevertheless, the "worn-off" lamina extracted in SDCL was neglected in these reports. We aimed to develop a simple mathematical model to analyze the relationship between the effective LOS and SCD, taking into consideration the worn-off lamina. MATERIAL AND METHODS A total of 106 patients treated by SDCL at our hospital were included in this study. Pre-operative and post-operative SCDs were assessed using a picture archiving and communication system (PACS) based on computed tomography scans. Mini-plate sizes as well as drill bit diameters were recorded in detail in order to determine the effective LOS for each vertebral lamina involved.

RESULTS SCD in all patients was increased significantly after SDCL (P<0.01). A linear correlation was found between effective LOS and the post-operative SCD increment from C3 to C7 (R²>0.933, P<0.001). The 12 mm mini-plate was most often used in SDCL, accounting for 64.45% of all cases, whereas 10 mm and 16 mm mini-plates were the least used, accounting for 3.85% and 3.00%, respectively. CONCLUSIONS There is a strong linear correlation between effective LOS and the post-operative SCD increment. The SCD was increased by about 0.5 mm per mm increase in effective LOS. Thus, post-operative SCD could be precisely calculated and predicted, enabling the selection of optimal mini-plate prior to SDCL.</description><identifier>ISSN: 1643-3750</identifier><identifier>ISSN: 1234-1010</identifier><identifier>EISSN: 1643-3750</identifier><identifier>DOI: 10.12659/MSM.919485</identifier><identifier>PMID: 31571675</identifier><language>eng</language><publisher>United States: International Scientific Literature, Inc</publisher><subject>Bone Plates ; Cervical Vertebrae - surgery ; China ; Clinical Research ; Humans ; Laminectomy - methods ; Laminoplasty - methods ; Models, Theoretical ; Spinal Canal - surgery ; Spinal Stenosis - surgery</subject><ispartof>Medical science monitor, 2019-10, Vol.25, p.7370-7375</ispartof><rights>Med Sci Monit, 2019 2019</rights><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c381t-1ab4455815acc22044e964273f5c4ad05aa6132b0b3bd6d18008d0e8b0557443</citedby></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC6788323/pdf/$$EPDF$$P50$$Gpubmedcentral$$Hfree_for_read</linktopdf><linktohtml>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC6788323/$$EHTML$$P50$$Gpubmedcentral$$Hfree_for_read</linktohtml><link.rule.ids>230,314,724,777,781,882,27905,27906,53772,53774</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/31571675$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Lu, Chang-Bo</creatorcontrib><creatorcontrib>Yang, Xiao-Jiang</creatorcontrib><creatorcontrib>Wu, Jia-Chang</creatorcontrib><creatorcontrib>Lin, Yun-Zhi</creatorcontrib><creatorcontrib>Sang, Hong-Xun</creatorcontrib><title>Clinical Investigation of the Association of Opening Size with Sagittal Canal Diameter Based on Single-Door Cervical Laminoplasty</title><title>Medical science monitor</title><addtitle>Med Sci Monit</addtitle><description>BACKGROUND Many clinical studies have assessed the association of laminoplasty opening size (LOS) with sagittal canal diameter (SCD) based on single-door cervical laminoplasty (SDCL).
