Lumbar disc herniation is a common and frequent disease in orthopedics, with back and leg pain and restricted lumbar activities as the main manifestations, causing great physical and mental pain to patients and huge medical costs to society and individuals, and is currently receiving increasing clinical attention. As early as 1934, Mixetr and Barr of Harvard Medical School first confirmed and cured lumbar disc herniation through surgery, this medical contribution created the so-called intervertebral disc era, and then countries have carried out intervertebral disc surgery, the traditional way of intervertebral disc surgery using total laminectomy, half laminectomy, unilateral up and down pushing bone part laminectomy, its main complications are infection, vascular injury The main complications include infection, vascular injury, nerve injury, dural pseudocyst, spinal instability and lower lumbar spine surgery failure syndrome. It is because of the drawbacks of traditional surgery that minimally invasive surgery for lumbar disc herniation has come into being. It has gone through several stages such as chemical pulp nucleolysis therapy, percutaneous disc removal, automatic percutaneous discectomy, arthroscopic discectomy, percutaneous endoscopic laser discectomy, and posterior microendoscopic discectomy. With the development of computer intelligence, fiber optic technology, fuzzy technology, and nanotechnology, the surgical treatment of lumbar discs will become more minimally invasive and limited. However, minimally invasive surgery requires expensive instrumentation and narrow surgical indications, while small incisional openings, which cause less damage to the spine, are less expensive to treat, do not require expensive equipment, and have a wider range of indications. However, studies have shown that regardless of the surgical approach, about 45% (30%-70%) of patients with lumbar disc herniation have residual back pain, about 30% (22%-45%) have residual leg pain, and about 60% have reduced lumbar spine mobility after surgery, so postoperative rehabilitation of lumbar disc herniation should not be neglected and should be an important part of the surgical treatment of lumbar disc herniation. The current study confirmed that one of the reasons for the poor postoperative outcome of lumbar disc herniation is inappropriate postoperative rehabilitation or neglect of postoperative rehabilitation, for example, Xie Minghua et al. reported a case of lower limb paraplegia in an elderly patient 6 hours after surgery due to inappropriate postoperative management. Yang Junli et al. found that patients with long postoperative bed rest and extensive total laminectomy had more long-term complications. Zhao Yi et al. reported poor postoperative outcomes due to postoperative lumbar instability, adhesions and scars. In order to improve postoperative outcomes and reduce complications, clinicians have begun to conduct experimental studies on postoperative rehabilitation therapy in recent years. Hou Jishou et al. observed 300 cases of lumbar disc herniation with nucleus pulposus removal and concluded that postoperative functional exercise could enhance muscle strength and endurance, improve spinal stability and flexibility, improve muscle status, and release adhesions. It has been suggested that the choice of postoperative bed rest and functional exercise time is related to the immediate and long-term postoperative effects. However, the research on early postoperative rehabilitation treatment is not deep enough, so it is necessary to conduct in-depth research on the methods of early rehabilitation treatment to make it scientific and standardized in order to shorten the treatment course, reduce complications, and improve the near- and long-term efficacy. In this topic, functional exercise and Chinese herbal medicine topical wound washing are used as the treatment means after lumbar disc herniation open surgery to explore the methods and efficacy of postoperative lumbar disc herniation.
