The following parameters were used to evaluate the effect: palmar tilt, radial inclination, VAS score, DASH score and wrist function. The severity of UV existed widely, accounting for 93.1% (108 cases). The severity of UV correlated with palmar tilt, radial inclination, grip strength, VAS score, DASH score and the wrist function (P\u2009&lt;\u20090.05). Log-rank analysis showed that the severity of UV, palmar tilt, radial inclination were important factors influencing the joint function postoperatively (P\u2009&lt;\u20090.0 5). Multivariate analysis confirmed that the severity of UV was an independent and significant factor on wrist function (P\u2009=\u20090.010). And the palmar tilt was also an important factor influencing wrist function (P\u2009=\u20090.047). The severity of ulnar variance compared with contralateral hand is an independent and significant factor on wrist function, which should be considered as an important step during preoperative plan.<\/jats:p>","DOI":"10.1038\/s41598-018-36616-5","type":"journal-article","created":{"date-parts":[[2019,2,18]],"date-time":"2019-02-18T11:03:22Z","timestamp":1550487802000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The severity of ulnar variance compared with contralateral hand: its significance on postoperative wrist function in patients with distal radius fracture"],"prefix":"10.1038","volume":"9","author":[{"given":"Xu","family":"Jianda","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuxing","family":"Qu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Huan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chong","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wang","family":"Bin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shen","family":"Pengfei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,2,18]]},"reference":[{"issue":"6","key":"36616_CR1","first-page":"443","volume":"62","author":"R Tosti","year":"2011","unstructured":"Tosti, R., Foroohar, A., Park, M.
