In total, 43 patients (11 males, 32 females) with Kummell disease who received bilateral PVP were included in the study. The patients were divided into front\u2010opening cannulas (FOC) group with front\u2010opening cannulas and side\u2010opening cannulas (SOC) group with side\u2010opening cannulas. All patients were followed up for 6\u2009months. The patient general information such as gender, age, bone density, compression ratio, operative time, and location of fracture vertebrae were recorded. Visual analogue scale (VAS), Oswestry Disability Index (ODI), bone cement distribution, radiation exposure time, bone cement leakage rate and vertebral height, and kyphosis angle were measured and compared for two groups before surgery, 1\u2009day and 6\u2009months after surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 43 patients were enrolled, including 11 males and 32 females, aged 61\u201384\u2009years. The bone density (T value) was 2.5\u2009\u00b1\u20090.6 in FOC group and 2.4\u2009\u00b1\u20090.6 in SOC group (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). The compression ratio and operative time were 36.1%\u2009\u00b1\u200913.0%, 39.3\u2009\u00b1\u20097.9\u2009min in FOC group and 35.2%\u2009\u00b1\u200913.7%, 40.0\u2009\u00b1\u200910.7\u2009min in SOC group (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). There was no significance between FOC and SOC groups in the location of fracture vertebrae. All patients underwent at least 6\u2009months of follow\u2010up. At 6\u2009months postoperatively, the VAS and ODI were significantly higher in the FOC group (3.0\u2009\u00b1\u20090.8, 35.7%\u2009\u00b1\u20092.1%) than in the SOC group (1.3\u2009\u00b1\u20090.4, 18.6%\u2009\u00b1\u20092.4%) (<jats:italic>P<\/jats:italic> &lt;\u20090.05). The cement leakage rate of the SOC group was 4.8%, which was lower than that of the FOC group (31.8%, <jats:italic>P<\/jats:italic> &lt;\u20090.05), and the bone cement distribution ratio was higher than that of the FOC group (63.1%\u2009\u00b1\u20097.9% <jats:italic>vs<\/jats:italic> 40.5%\u2009\u00b1\u20098.6%, <jats:italic>P<\/jats:italic> &lt;\u20090.05). At 6\u2009months after operation, the height of the anterior and posterior vertebral bodies of the patients in the SOC group restored better than the FOC group (anterior SOC: FOC 5.1\u2009\u00b1\u20090.5\u2009mm <jats:italic>vs<\/jats:italic> 4.5\u2009\u00b1\u20090.5\u2009mm; posterior SOC: FOC 0.6\u2009\u00b1\u20090.1\u2009mm <jats:italic>vs<\/jats:italic> 0.3\u2009\u00b1\u20090.1\u2009mm, <jats:italic>P<\/jats:italic> &lt;\u20090.05), and the kyphosis correction was more obvious than patients in FOC group (SOC: FOC 8.5\u00b0\u2009\u00b1\u20091.4\u00b0 <jats:italic>vs<\/jats:italic> 4.6\u00b0\u2009\u00b1\u20090.8\u00b0, <jats:italic>P<\/jats:italic> &lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Percutaneous vertebroplasty with side\u2010opening cannula is safe and effective in avoiding bone cement leakage, improving bone cement distribution, and restoring vertebral height.<\/jats:p><\/jats:sec>","DOI":"10.1111\/os.12730","type":"journal-article","created":{"date-parts":[[2020,7,8]],"date-time":"2020-07-08T02:46:57Z","timestamp":1594176417000},"page":"1190-1198","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Percutaneous Vertebroplasty with Side\u2010Opening Cannula or Front\u2010Opening Cannula in the Treatment of Kummell Disease?"],"prefix":"10.1111","volume":"12","author":[{"given":"Xi\u2010fa","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Spinal Surgery Zibo Central Hospital  ZiBo China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Ping","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Rizhao Central Hospital  Rizhao China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang\u2010qin","family":"Zeng","sequence":"additional","affiliation":[{"name":"Department of Radiology Zibo Central Hospital  ZiBo China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Feng","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics Chongqing University Central Hospital  Chongqing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Spinal Surgery Zibo Central Hospital  ZiBo China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tao","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Spinal Surgery Zibo Central Hospital  ZiBo China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2435-210X","authenticated-orcid":false,"given":"Dong\u2010jin","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Spinal Surgery The Second Hospital of Shandong University  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,7,7]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.2147\/CIA.S131023"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11657-014-0182-3"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-016-3712-7"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.2174\/1874325001509010107"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00198-013-2458-7"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2018.09.130"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aott.2018.05.002"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00198-012-2102-y"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neurad.2013.07.004"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1258\/ar.2012.120222"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2019.08.029"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.3340\/jkns.2010.48.2.125"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jss.2014.12.053"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.85B1.13026"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-009-1205-4"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2017.09.148"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.3892\/etm.2016.3369"},{"key":"e_1_2_6_19_1","first-page":"291","article-title":"Kummell's disease: pathophysiology, diagnosis, treatment and the role of nuclear medicine.
