However, for a small number of patients, these symptoms are relieved immediately after surgery but aggravated soon after, and then relieved after short\u2010term full rest or conservative treatment. The aim of the study was to demonstrate this short\u2010term recurrent phenomenon, termed rebound pain.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective study was conducted on 144 patients who underwent single\u2010segment PELD from May 2017 to June 2020. Postoperative patients were divided into a rebound pain group and a non\u2010rebound pain group. For the former group, general information, symptom characteristics and visual analogue score (VAS) changes in rebound pain were summarized. For both groups, postoperative efficacy was evaluated by recent VAS of low back and leg pain in the remission stage, the Oswestry disability index (ODI) and the modified MacNab criteria at the last follow\u2010up. Logistic regression analysis was used to identify predictors for rebound pain.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The VAS and ODI exhibited significant improvements at the last follow\u2010up of average 15.4\u2009months (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). The successful outcomes according to the modified MacNab criteria reached 94.4%. A total of 15 patients (10.4%) experienced rebound pain. The typical feature was pain that usually began within 1\u2009month after surgery and lasted for less than 1\u2009month. The symptoms were mainly leg pain with or without low back pain. The range of pain was equal to or less than that before surgery. The symptoms were relieved after conservative treatment. In logistic regression model, postoperative return\u2010to\u2010work time\u2009&gt;\u200945\u2009days was found as a protective factor for rebound pain (p\u00a0=\u00a00.031).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Although rebound pain with multiple characteristics and a short duration had no significant effect on long\u2010term postoperative efficacy, its high incidence often caused unnecessary concern in both patients and doctors. As a result, careful differentiation of rebound pain from other postoperative complications is needed.<\/jats:p><\/jats:sec>","DOI":"10.1111\/os.13088","type":"journal-article","created":{"date-parts":[[2021,10,17]],"date-time":"2021-10-17T01:28:26Z","timestamp":1634434106000},"page":"2196-2205","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["A
