One-hole split endoscope technique for migrated lumbar disc herniation: a single-centre, retrospective study of a novel technique.

BACKGROUND: Lumbar disc herniation (LDH) is one of the most common diseases of the spine, and migrated LDH is a more serious type, associated with nerve root function injury or abnormality. Regarding the increasing surgery adoption of treating migrated LDH, we aimed to investigate the clinical efficacy and safety of discectomy with a novel technique-one-hole split endoscope (OSE) technique. METHODS: This was a retrospective analysis of migrated LDH treated between December 2020 and September 2021. Hospitalization time, operative duration, intraoperative blood loss, number of fluoroscopy exposures, incision length, postoperative facet preservation rate, number of excellent-good cases, lower back and leg visual analogue score (VAS), Oswestry Disability Index (ODI) and surgical complications were compared between high-grade migration group (82 cases) and low-grade migration group (148 cases). The Macnab criteria was used to evaluate the clinical outcome. The Shapiro‒Wilk test was used to test measurement data, and the χ2 test was used to test counting data. RESULTS: There was no significant difference in hospitalization time, operative duration, intraoperative blood loss, number of fluoroscopy exposures, incision length or postoperative facet preservation rate between the two groups by independent sample t test or nonparametric test. At any time point, the lower back and leg VAS and ODI of the two groups were significantly improved compared to those before the operation, but there was no significant difference between the two groups at the same time point by two-way repeated measures ANOVA. There were two cases of postoperative nerve root stimulation symptoms in the high-grade migration group and three cases in the low-grade migration group. There was one patient reoperated in the high-grade migration group. There was no significant difference in number of excellent-good cases between the two groups. The overall excellent-good rate was 89.6%. CONCLUSION: The OSE technique has the advantages of less trauma, faster recovery, complete removal of the nucleus pulposus and a satisfactory early clinical efficacy in the treatment of migrated LDH.

Application of flipped classroom based on CDIO concept combined with mini-CEX evaluation model in the clinical teaching of orthopedic nursing.

BACKGROUND: After the COVID-19 epidemic, the state has paid more attention to the clinical teaching function of affiliated hospitals of colleges and universities. Strengthening the integration of medicine and education and improving the quality and effect of clinical practice teaching are critical challenges facing medical education. The difficulty of orthopedic teaching lies in the characteristics of a wide variety of diseases, strong professionalism, and relatively abstract characteristics, which affect the initiative, enthusiasm, and learning effect of nursing students. In this study, a flipped classroom teaching plan based on the CDIO (conceive-design-implement-operate) concept was constructed and practiced in the orthopedic nursing student training course to improve the effect of practical teaching, and it is convenient for teachers to implement more effective and targeted teaching in the flipped classroom of nursing education and even medical education in the future. METHODS: Fifty undergraduate nursing students who practiced in the Orthopedics Department of a tertiary hospital in June 2017 were enrolled in the control group, while 50 undergraduate nursing students who practiced in the same department in June 2018 were enrolled in the intervention group. The intervention group adopted the flipped classroom teaching mode of the CDIO concept, whereas the control group adopted the traditional teaching mode. After finishing the department practice task, the students in the two groups completed the evaluation of theory, operation skills, independent learning ability, and critical thinking ability. They completed the evaluation of clinical practice ability in eight dimensions, including four processes of nursing procedures, humanistic care ability, and evaluation of clinical teaching quality for two groups of teachers. RESULTS: After teaching, the clinical practice ability, critical thinking ability, autonomous learning ability, theoretical and operational performance, and evaluation of clinical teaching quality in the intervention group were significantly higher than those in the control group (all p < 0.05). CONCLUSION: The CDIO-based teaching mode can stimulate the independent learning ability and critical thinking ability of nursing interns, promote the organic combination of theory and practice, improve their ability to comprehensively use theoretical knowledge to analyze and solve practical problems, and improve teaching effectiveness.

Nursing and safety of silver needle diathermy treating ankylosing spondylitis.

This paper aims to discuss the nursing and safety of silver needle diathermy in the treatment for ankylosing spondylitis. We nursed 46 patients with ankylosing spondylitis treated with silver needle diathermy. Specific nursing was focused on physical condition evaluation and mental nursing before treatment, observation during and after treatment, diet nursing, needle eye nursing, functional training and propaganda and education when discharged. The result suggested that all the patients received mental nursing, diet guide, skin care, health education, functional training and follow-up visit from the nurse and all of them could endure silver needle diathermy as discomfort or drug allergy was barely found, so were slight scald and skin infection nearby the needle eye caused by fainting during acupuncture, accidental puncture or overheat. Follow-up visit showed that no patient suffered obvious untoward effect and the pain, joint range of motion and living condition were distinctly improved a week after discharging. In conclusion, during the treatment for ankylosing spondylitis applying silver needle diathermy, the nursing before, during and after the treatment can obviously reduce the complication, accelerate the recovery, which is highly safe.

Effect and nursing study of traditional Chinese medicine preparation huayu zhitong powder in the treatment of distal radius fracture.

This paper aims to discuss the effect of traditional Chinese medicine preparation Huayu Zhitong powder in the treatment of distal radius fracture. In this paper, 200 patients with distal radius fracture were randomly divided into treatment group and control group. Patients in treatment group orally took Huayu Zhitong powder, while patients in control group were treated with traditional Shangke Jiegu tablets with traditional Chinese medicine composition. After fixed in a cast plaster, patients in the two groups were supervised the disappearance time of pain by adopting NRS (Numerical rating scale) from scale 0 to 10. Besides, they returned at day 5 and day 8 respectively, and then they were observed the swelling affected part. At day 14, day 28, and day 56 after reduction they respectively took an x-ray. Then they would be graded according to the growth of osteotylus and the clinical effects were evaluated based on the grade. Finally, the treatment group worked better in relief effect than the control group. At day 8, the treatment group worked better in detumescence than the control group. At day 28, the recovery effect in treatment group was found to be better than the other. From these, it is shown that the traditional Chinese medicine works much better in the treatment of distal radius fracture than traditional treatment medicine. Thus it is of great worth spreading for use.
