Effectiveness of different surgical methods in the treatment of acute central cord syndrome without fractures and dislocations of the cervical spine.

BACKGROUND: Acute central cord syndrome (ACCS) without fractures or dislocations is the most common form of incomplete spinal cord injury. OBJECTIVE: To evaluate the effectiveness of different surgical methods in the treatment of acute central cord syndrome without fractures or dislocations of the cervical spine. METHODS: A total of 164 patients with ACCS without fracture or dislocation of the cervical spine treated in our hospital from May 2012 to October 2019 were recruited and assigned to study group A and study group B according to different treatment modalities, with 82 cases in each group. Study group A underwent anterior cervical discectomy and fusion, and study group B was treated with posterior cervical laminectomy. The American Spinal Injury Association (ASIA) classification and motor scores of all cases at admission and at discharge were recorded, and the treatment outcomes of the two groups were compared. RESULTS: No significant differences were found in the ASIA classification and ASIA motor scores between the two groups at admission (P> 0.05). One year after surgery, the ASIA motor scores and sensory scores were not statistically significant between the two groups (P> 0.05) but showed significant improvement compared to the preoperative scores (P< 0.05). CONCLUSION: Both anterior cervical discectomy and fusion and posterior cervical laminectomy can improve the ASIA classification, ASIA motor scores, and sensory scores of ACCS patients without fractures or dislocations of the cervical spine. Therefore, surgical methods should be adopted based on the patients' conditions.

The Efficacy of Anterior Cervical Corpectomy and Fusion and Posterior Total Laminectomy on Cervical Spinal Cord Injury and Quality of Life.

This study is aimed at investigating the efficacy of anterior cervical corpectomy and fusion and posterior total laminectomy in the treatment of cervical spinal cord injury and assessing the impact of the two approaches on cervical spine function and patient quality of life. Retrospectively analyze the clinical data from 180 patients with cervical spinal cord injury who were admitted to the First Affiliated Hospital of Hebei North University from June 2019 to June 2021. The patients were divided into an anterior approach group (n = 89, treated with anterior cervical corpectomy and fusion) and a posterior approach group (n = 91, treated with posterior total laminectomy). The amount of blood loss in the posterior approach group was larger compared to the anterior approach group. Patients in the posterior approach group had higher wound diameters and operation times compared to the anterior approach group, as well as the operation cost. The visual analogue scale (VAS) scores of patients in the posterior approach group were significantly higher than in the anterior approach group one month after operation. The Japanese Orthopaedic Association (JOA), neck disability index (NDI), and American Spinal Injury Association (ASIA) scores of patients in both groups at 1, 6, and 9 months after surgery were higher compared to those before surgery, yet no significant differences were observed between the two groups. Also, no significant difference was observed in the incidence of complication and the quality of life between the two groups before and after treatment. Anterior cervical corpectomy and fusion and posterior total laminectomy can effectively restore the cervical nerve function in the treatment of cervical spinal cord injury. However, anterior subtotal vertebral resection is associated with improved perioperative indicators compared to posterior total laminectomy. Clinically, surgical methods can be selected according to imaging findings, the general condition of patients, and individual economic status.

Efficacy of NHP66 Bioactive Cage on Patients with Cervical Spine Injury in Short-Track Speed Skating.

BACKGROUND: Short-track speed skating (STSS) is an extreme sport in pursuit of extreme speed and explosive force. In such a sport, once athletes fall down, they are susceptible to serious cervical spine injury (CSI) under the inertia of high-velocity movement. Nanohydroxyapatite/polyamide 66 (NHP66) bioactive cage is a high-tech product of nanotechnology in the medical field in recent years. With a structure similar to that of human cortical bone, NHP66 bioactive cage has extremely high toughness and strength, which tailors to the needs of STSS. OBJECTIVE: This study mainly analyzed the therapeutic effect of NHP66 on patients with CSI in STSS, aiming to provide new opportunities for the treatment of this patient population. METHODS: A total of 51 patients with CSI treated in our hospital were enrolled, including 19 cases of short-track speed skaters (observation group) and 32 cases of car accidents, falls from heights, or collision injuries (control group). The relevant surgical indicators (operation time, intraoperative blood loss, etc.), the incidence of adverse reactions, the Cobb angle of cervical lordosis before and after surgery, and the fusion segment height of the cage were observed and compared between the two groups. Postoperative pain was evaluated by the visual analog scale (VAS), improvement of spinal cord injury was assessed by the American Spinal Cord Injury Association (ASIA) Impairment Scale, and bone fusion, bone subsidence, and other motor functions were assessed by the Japanese Orthopaedic Association (JOA) score rating system. RESULTS: The operation time, intraoperative blood loss, and incidence of adverse reactions in the observation group were significantly lower than those in the control group. The Cobb angle of cervical lordosis and the fusion segment height of cage increased significantly higher in both groups after surgery. In addition, the VAS scores of the observation group 2 h and 3 d after operation were significantly lower than those of the control group. In terms of improvement of spinal cord injury, ASIA and JOA scores in the observation group were significantly higher than those before treatment and in the control group. There was no significant difference in bone fusion activity between the two groups. CONCLUSIONS: In this study, it is found through experiments that NHP66 has higher safety and application value than autogenous iliac bone, confirming that NHP66 can achieve significant results as a cage for anterior cervical decompression and iliac bone graft fusion and internal fixation in short-track speed skaters after CSI.

Clinical Effect of Doxycycline Combined with Compound Sulfamethoxazole and Rifampicin in the Treatment of Brucellosis Spondylitis.

OBJECTIVE: The purpose of this study was to determine the clinical value of triple antibiotic therapy consisting of doxycycline, compound sulfamethoxazole and rifampicin in the treatment of brucellosis spondylitis. METHODS: A retrospective analysis was performed on 100 patients with brucellosis spondylitis admitted to the First Affiliated Hospital of Hebei North University from March 2016 to June 2019. Patients were divided into the following two groups: the control group (n = 50) treated with dual antibiotic therapy (rifampicin + compound sulfamethoxazole), and the observation group (n = 50) treated with triple antibiotic therapy (rifampicin + doxycycline + compound sulfamethoxazole). The treatment effect, low back pain relief, levels of erythrocyte sedimentation rate (ESR), procalcitonin (PCT) and C-reactive protein (CRP), as well as the adverse reactions were compared between the two groups. RESULTS: The response rate of the observation group was significantly higher than that of the control group (P < 0.05). Before treatment, there was no significant difference in the low back pain assessed by the visual analogue scale (VAS), or levels of ESR, PCT and CRP between the two groups (P > 0.05). But after treatment, the VAS score and the levels of ESR, PCT and CRP in observation group were lower than those in the control group (P < 0.05). No significant difference was found in the incidence of adverse reactions (P > 0.05). CONCLUSION: The triple antibiotic therapy of doxycycline, compound sulfamethoxazole and rifampicin is effective in the treatment of brucellosis spondylitis. It can significantly alleviate patients' back pain and inflammation with a high safety profile, which is worthy of clinical application.

An analysis of the heart rates and the therapeutic effect of aminophylline injections in patients with acute cervical spinal cord injuries and bradycardia.

OBJECTIVE: To investigate the changes in the heart rates and the clinical effectiveness of aminophylline injections in acute cervical spinal cord injury (ACSCI) patients with bradycardia. METHODS: This retrospective study was conducted by studying the clinical data of 100 ACSCI patients also suffering from bradycardia admitted to our hospital from June 2019 to June 2020. The patients were randomly placed into a control group (n=50) that was administered atropine therapy and a test group (n=50) that was administered aminophylline injections. The changes in the patients' heart rates and the clinical effectiveness were analyzed. RESULTS: After the treatment, the test group had a significantly higher average heart rate, shorter heart rate recovery times, and a lower bradycardia recurrence rate than the control group (all P<0.05). The systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels in the test group were significantly higher than they were in the control group (all P<0.05). Remarkably higher clinical effectiveness and satisfaction rates and a significantly lower incidence of adverse reactions were observed in the test group compared to the control group (all P<0.05). In addition, the Japanese Orthopaedic Association (JOA) cervical spine scores were similar in the two groups (P>0.05). CONCLUSION: For ACSCI patients also suffering from bradycardia, aminophylline injections ameliorate the clinical heart rate and have a good clinical effectiveness with few adverse reactions, so the treatment merits clinical promotion and application.

Synchronized and integrated prehospital treatment for acute cervical spinal cord injury.

OBJECTIVE: To explore the effect of synchronized and integrated prehospital treatment strategies for on-site first aid, rescue transport and prehospital first aid in patients with acute cervical spinal cord injury. METHODS: A prospective non-randomized controlled study was designed to include patients with acute cervical spinal cord injury. A total of 50 patients were included in a Control group (before the implementation of synchronized and integrated prehospital treatment), and 50 patients were included in an Observation Group (after the implementation of synchronized and integrated prehospital treatment). We compared the timeliness of prehospital treatment, the proportion of patients received methylprednisolone treatment within 3 h after injury, the changes in Japanese Orthopaedic Association (JOA) score during transport, the incidence of adverse events, the clinical outcomes, the number of prehospital deaths, the case number of paralysis and the recovery of postoperative neural function between the two groups. RESULTS: Compared with the Control group, the Observation group showed significantly shorter time from injury to admission, from injury to receiving methylprednisolone pulse therapy, as well as from injury to receiving dehydrating agents and diuretics (all P<0.001). The proportion of patients received methylprednisolone treatment within 3 h after injury was significantly higher in the Observation group than that in the Control group (P<0.05). There was no significant change in the JOA score in the Observation group before and after the transport, while the score was significantly lower in the Control group after the transport (P<0.001). The JOA score was higher in the Observation group than that in the Control group at admission (P<0.001). The Observation group also showed decreased incidences of adverse events, mortality, and paralysis rate (all P<0.05) as well as better recovery of postoperative neural function (P<0.001) when compared with the Control group. CONCLUSION: Synchronized and integrated prehospital treatment has a significant effect in patients with acute cervical spinal cord injury through shortening the admission time, reducing the risk of adverse events, and improving the rescue effect and the prognosis of neural function.

[Comparison of effectiveness between two surgical methods in treatment of thoracolumbar brucella spondylitis].

OBJECTIVE: To compare the effectiveness between the method of simple posterior debridement combined with bone grafting and fusion and internal fixation and the method of one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in the treatment of thoracolumbar brucella spondylitis so as to provide the reference for the clinical treatment. METHODS: A retrospective analysis was made on the clinical data of 148 cases of thoracolumbar brucella spondylitis between January 2002 and January 2012. Simple posterior debridement combined with bone grafting and fusion and internal fixation was used in 78 cases (group A), and one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in 70 cases (group B). There was no significant difference in gender, age, disease duration, involved vertebral segments, erythrocyte sedimentation rate (ESR), visual analogue scale (VAS) score, neural function grade of America Spinal Injury Association (ASIA), and kyphosis Cobb angle before operation between 2 groups (P > 0.05). The peri operation period indexes (hospitalization time, operation time, and intraoperative blood loss) and the clinical effectiveness indexes (VAS score, ASIA grade, Cobb angle, and ESR) were compared; the bone fusion and the internal fixation were observed. RESULTS: Incision infection and paravertebral and/or psoas abscess occurred in 2 and 3 cases of group A respectively. All incisions healed by first intention and 2 cases had pneumothorax in group B. The operation time and the hospitalization time of group A were significantly shorter than those of group B (P < 0.05), and the intraoperative blood loss of group A was significantly lower than that of group B (P < 0.05). All of the cases in 2 groups were followed up 14- 38 months, 25 months on average. The VAS, ESR, and Cobb angle were significantly decreased at each time point after operation when compared with preoperative ones in 2 groups (P < 0.05), but no significant difference was found between 2 groups (P > 0.05). The neurological function was significantly improved at 3 months after operation; there were 1 case of ASIA grade C, 14 cases of grade D, and 63 cases of grade E in group A, and there were 1 case of grade C, 11 cases of grade D, and 58 cases of grade E in group B; and difference was not significant (Z = 0.168, P = 0.682). The grafting bone fusion was observed in both groups. The fusion time was (8.7 ± 0.3) months in group A and (8.6 ± 0.4) months in group B, showing no significant difference (t = 0.591, P = 0.601) was found. At last follow-up, no loosening or fracture of internal fixation was found. CONCLUSION: Based on regular medicine therapy, the effectiveness of the two methods is satisfactory in the treatment of thoracolumbar brucella spondylitis as long as the operation indications should be controlled strictly.
