RESUMO
BACKGROUND: Percutaneous vertebroplasty (PVP) has been used widely to treat osteoporotic vertebral compression fractures (OVCFs). However, it has many disadvantages, such as excessive radiation exposure, long operation times, and high cement leakage rates. This study was conducted to explore the clinical effects and safety of the use of a three-dimensional (3D)-printed body-surface guide plate to aid PVP for the treatment of OVCFs. METHODS: This prospective cohort study was conducted with patients with OVCFs presenting between October 2020 and June 2021. Fifty patients underwent traditional PVP (group T) and 47 patients underwent PVP aided by 3D-printed body-surface guide plates (3D group). The following clinical and adverse events were compared between groups: the puncture positioning, puncture, fluoroscopy exposure and total operation times; changes in vertebral height and the Cobb angle after surgery relative to baseline; preoperative and postoperative visual analog scale and Oswestry disability index scores; and perioperative complications (bone cement leakage, neurological impairment, vertebral infection, and cardiopulmonary complications. RESULTS: The puncture, adjustment, fluoroscopy, and total operation times were shorter in the 3D group than in group T. Visual analog scale and Oswestry disability index scores improved significantly after surgery, with significant differences between groups (both p < 0.05). At the last follow-up examination, the vertebral midline height and Cobb angle did not differ between groups. The incidence of complications was significantly lower in the 3D group than in group T (p < 0.05). CONCLUSION: The use of 3D-printed body-surface guide plates can simplify and optimize PVP, shortening the operative time, improving the success rate, reducing surgical complications, and overall improving the safety of PVP.

Background: With the accelerated pace of life in modern society, changes in work style, and the popularity of computers, the prevalence of cervical spondylosis (CSR) is increasing, and the age of onset is advancing. Once suffering from this disease, it is often difficult to cure and recurring, with complex clinical symptoms, causing a serious impact on human health. Objective: To evaluate the efficacy of manipulation and cervical traction in the treatment of radical cervical spondylosis. Methods: The PubMed, CNKI, and Wanfang databases were searched for literature. The literature related to this study was included according to selective criteria and inhibitory elimination criteria, and valuable information was selected for statistical analysis, resulting in a total of 11 randomized controlled trials with 994 subjects. Results: The short-term efficacy of manual treatment for CSR was superior to that of cervical traction alone (P < 0.05); subgroup analysis showed that the short-term efficacy of pulling or rotational manipulation was superior to that of cervical traction (P < 0.05). The mean difference between symptoms and manipulation VAS scores was higher before and after treatment when compared with cervical traction for CSR (P < 0.05); the subgroup analysis showed that VAS scores, upper extremity anesthesia scores, and survivorship scores were lower for pulling or rotating manipulation than for cervical traction (P < 0.05). Conclusion: The advantages of manual therapy in terms of short-term efficacy, VAS pain scores, neck pain, upper extremity anesthesia, and survivorship improvement provide a theoretical basis for its clinical impact.
RESUMO
BACKGROUND: This study assessed the therapeutic effect of one-stage percutaneous endoscopic debridement and lavage (PEDL) combined with percutaneous pedicle screw fixation (PPSF) in the treatment of lumbar pyogenic spondylodiscitis. METHODS: From March 2017 to October 2019, 51 patients diagnosed with pyogenic spondylodiscitis underwent PPSF followed by PEDL in our department. Biopsy specimens were examined for microorganisms and evaluated histopathologically. Clinical outcomes were assessed by physical examination, routine serological testing, visual analogue scale (VAS), Oswestry Disability Index (ODI) and imaging studies. RESULTS: Of the enrolled patients, the operation time ranged from 90 min to 114 min every level with an average of 102 min, and the average drainage time ranged from 6 days to 10 days with an average of 7.4 days. All patients who complained of lower back pain symptoms were more relieved than before surgery. Causative pathogens were identified in 20 of 51 biopsy specimens; Staphylococcus aureus was the most prevalent. However, there were eight patients with postoperative complications. The mean follow-up was 25.0 ± 3.8 (range: 20-32) months. Inflammatory markers showed that infection was controlled. The VAS and ODI improved significantly. At the last follow-up, magnetic resonance imaging showed that the infected lesions had disappeared. CONCLUSION: PEDL supplementing PPSF may be useful for patients with single-level lumbar pyogenic spondylodiscitis, as it is minimally invasive, especially for patients who cannot undergo conventional open surgery due to poor health or advanced age.
