OBJECTIVE: To review the application and progress of unilateral biportal endoscopy (UBE) technology in the treatment of cervical degenerative diseases, and to provide reference for clinical treatment decisions. METHODS: The literature related to UBE technology in the treatment of cervical spondylotic radiculopathy (CSR) and cervical spondylotic myelopathy (CSM) at home and abroad was extensively reviewed, and the surgical methods, indications, effectiveness, and safety were analyzed and summarized. RESULTS: UBE technology is effective in the treatment of CSR and CSM, and has the advantages of good surgical field, reducing the injury of the posterior structure of the cervical spine, and protecting the facet joint process, but in general, the indications are relatively narrow, limited to single-segment or adjacent double-segment lesions, and the requirements for the operator are relatively high, and the learning curve is long. CONCLUSION UBE technology can be applied to the treatment of CSR and CSM, but it needs to be carried out by experienced UBE surgeons for specific cases.

OBJECTIVE: To explore clinical effect of Zero-profile intervertebral fusion with cage-titanium plate in treating multilevel cervical spondylotic myelopathy. METHODS: From January 2016 to January 2020, 107 patients with multisegmental cervical spondylotic myelopathy treated by surgery were retrospectively analyzed and divided into Hybrid group and control group according to different surgical methods. There were 54 patients in Hybrid group, including 42 males and 12 females, aged from 33 to 77 years old with an average of (57.3±9.5) years old;20 patients with C₃-C₆, 27 patients with C₄-C₇ and 7 patients with C₃-C₇;Zero-profile intervertebral fusion with cage-titanium plate internal fixation was performed. There were 53 patients in control group, including 34 males and 19 females;aged from 36 to 79 years old with an average of (57.8±8.9) years old;17 patients with C₃-C₆, 27 patients with C₄-C₇, and 9 patients with C₃-C₇;titanium plate interbody fusion fixation was performed. Operation time, blood loss and complications between two groups were compared, visual analogue scale (VAS), Japanese Orthopedic Association (JOA) scores and neck disability index (NDI) were used to assess recovery of clinical symptoms;cervical lordosis (CL), cervical sagittal vertical axis (C-SVA), and T₁ slope (T₁S) were measured and compared to evaluate cervical sagittal plane parameters. RESULTS: All patients were followed up, Hybrid group was followed up for 24 to 64 months with an average of (31.7±18.4) months, and control group was followed up for 24 to 65 months with an average of (32.6±15.8) months. There was no significant difference in follow-up time between two groups (P>0.05). Operation time and blood loss in Hybrid group were less than those in control group (P<0.05). VAS, JOA score and NDI were significantly improved between two groups at the lastest follow-up (P<0.05). There were no significant difference in VAS, JOA and NDI scores between two groups before and after operation (P>0.05). CL in both two groups at 3 months and the latest follow-up after operation were significantly improved than those before operation (P<0.05), there were no significant difference between two groups in T1S and C-SVA before and after operation (P>0.05). Postoperative dysphagia occurred in 2 patients in Hybrid group and 9 patients in control group, and had statistically difference in the incidence of dysphagia between two groups (χ²=5.112, P=0.024). During the follow-up, there were no complications such as loosening, displacement or fracture of internal fixation between two groups. CONCLUSION Compared with titanium plate interbody fusion, Zero-profile intervertebral fusion combined with cage-titanium plate for the treatment of multilevel cervical spondylotic myelopathy could shorten surgical time and blood loss, reduce surgical trauma and postoperative swallowing difficulties, and is conducive to early and rapid recovery.

PURPOSE: There are many infectious and inflammatory causes for elevated core-body temperatures, though they rarely pass 40 ℃ (104 ℉). The term "quad fever" is used for extreme hyperpyrexia in the setting of acute cervical spinal cord injuries (SCIs). The traditional methods of treating hyperpyrexia are often ineffective and reported morbidity and mortality rates approach 100%. This study aims to identify the incidence of elevated temperatures in SCIs at our institution and assess the effectiveness of using a non-invasive dry water temperature management system as a treatment modality with mortality. METHODS: A retrospective analysis of acute SCI patients requiring surgical intensive care unit admission who experienced fevers ≥ 40 ℃ (104 ℉) were compared to patients with maximum temperatures < 40 ℃. Patients ≥18 years old who sustained an acute traumatic SCI were included in this study. Patients who expired in the emergency department; had a SCI without radiologic abnormality; had neuropraxia; were admitted to any location other than the surgical intensive care unit; or had positive blood cultures were excluded. SAS 9.4 was used to conduct statistical analysis. RESULTS: Over the 9-year study period, 35 patients were admitted to the surgical intensive care unit with a verified SCI. Seven patients experienced maximum temperatures of ≥ 40 ℃. Six of those patients were treated with the dry water temperature management system with an overall mortality of 57.1% in this subgroup. The mortality rate for the 28 patients who experienced a maximum temperature of ≤ 40 ℃ was 21.4% (p = 0.16). CONCLUSION The diagnosis of quad fever should be considered in patients with cervical SCI in the presence of hyperthermia. In this study, there was no significant difference in mortality between quad fever patients treated with a dry water temperature management system versus SCI patients without quad fever. The early use of a dry water temperature management system appears to decrease the mortality rate of quad fever.

Objective: To compare the volumetric changes of cervical disc herniation (CDH) after cervical microendoscopic laminoplasty(CMEL),expansive open-door laminoplasty (EOLP) and conservative treatment. Methods: A retrospective study was conducted involving 101 patients with cervical spondylotic myelopathy(CSM),at the Department of Orthopaedic Surgery,the First Affiliated Hospital of Zhengzhou University from April 2012 to April 2021. The patients included 52 males and 49 females with an age of (54.7±11.8) years(range:25 to 86 years). Among them, 35 patients accepted CMEL treatment,33 patients accepted EOLP treatment,while 33 patients accepted conservative treatment. Volume data of CDH were measured by three-dimensional analysis of the initial and follow-up MRI images. The absorption rate and reprotrusion rate of CDH were calculated. The happening of resorption or reprotrusion was defined when the ratio was greater than 5%. The clinical outcomes and quality of life were evaluated by the Japanese Orthopaedic Association (JOA) score and the neck disability index (NDI).Quantitative data was analyzed by one-way ANOVA with post LSD-t test (multiple comparison) or Kruskal-Wallis test. Categorical data was analyzed by χ² test. Results: The follow-up time of the CMEL group,EOLP group and the conservative treatment group were (27.6±18.8)months,(21.6±6.9)months and(24.9±16.3)months respectively with no significant difference(P>0.05). Changes of CDH volume in patients:(1) There were 96 CDH of 35 patients in the CMEL group,among which 78 showed absorption. The absorption frequency was 81.3%(78/96) and the absorption rate was ranged 5.9% to 90.9%;9 CDH showed reprotrusion,the reprotrusion frequency was 9.4% (9/96) and the reprotrusion rate was 5.9% to 13.3%;(2) There were 94 CDH of 33 patients in the EOLP group,of which 45 showed absorption. The absorption prevalence was 47.9% (45/94) and the absorption rate was 5.0% to 26.7%;20 CDH showed reprotruded,with the reprotrusion frequency of 21.3% (20/94) and the reprotrusion rate was 5.8% to 28.3%;(3) There were 102 CDH in 33 patients of the conservative group. Among them, 5 showed absorption. The absorption frequency was 4.9% (5/102),and the absorption rate was 7.2% to 14.3%;58 CDH showed reprotruded with the re-protrusion ratio of 56.9% (58/102) and the re-protrusion rate was 5.4% to 174.1%. The absorption ratio and reprotrusion ratio of the CMEL group were statistically different from EOLP group or the conservative group (P<0.01).The absorption ratio and reprotrusion ratio of the EOLP group was different from conservative group (all P<0.01). In terms of clinical outcomes, the excellent/good rate of the JOA score and NDI scores in the CMEL group were different from that of conservative group (all P<0.01) but not from that of the EOLP group(P>0.05). Conclusions: CMEL is an effective method for the treatment of CSM,making CDH easier to resorption compared to the EOLP or conservative treatment,thus making a better decompression effect on the nerves. This study enlightened on a new strategy for the clinical treatment of CSM.

OBJECTIVE: To compare the clinical effects of total laminectomy with lateral mass screw fixation and single open-door laminoplasty in the treatment of cervical spinal cord injury without fracture and dislocation. METHODS: The clinical data of 75 patients with cervical spinal cord injury without fracture and dislocation treated from December 2014 to April 2020 were retrospectively analyzed, including 65 males and 10 females, aged from 33 to 83 years old with an average of (60.1±11.4) years. According to surgical method, the patients were divided into observation group (36 cases) and control group (39 cases). The observation group was treated with C₃-C₆ single open-door laminoplasty. In the control group, the C₃-C₆ whole lamina was opened by "uncovering", and the lateral mass screw was fixed and fused. The general conditions including operation time, intraoperative blood loss, hospital stay and complications such as axial pain, cerebrospinal fluid leakage, postoperative C₅ nerve palsy were recorded. Visual analogue scale(VAS), Nurick pain scale, Japanese Orthopaedic Association(JOA) scores and American Spinal Injury Association(AISA) injury scale were used to evaluate the improvement of clinical symptoms and related functional recovery 12 months after operation. RESULTS: There were no statistically significant differences in operation time, intraoperative blood loss and hospital stay between two groups(P>0.05). There were statistically significant differences in JOA, VAS, ASIA and Nurick scores of the all patients between 12 months after surgery and before surgery (P<0.05), and there was no significant difference between groups. There was significant difference in the incidence of C5 nerve root palsy and axial pain between two groups(P<0.05), but there was no significant difference in the complications of cerebrospinal fluid leakage between two groups (P>0.05). CONCLUSION Total laminectomy with lateral mass screw fixation and single open-door laminoplasty in treating cervical spinal cord injury without fracture and dislocation can obtain satisfactory results in restoring nerve function, alleviating pain and improving daily behavior, but single open-door laminoplasty has the advantages of less trauma and low incidence of complications.

OBJECTIVE: To explore the clinical effects of anterior cervical discectomy with fusion (ACDF) and anterior cervical corpectomy with fusion (ACCF) in treating adjacent two-segment cervical spondylotic myelopathy (CSM). METHODS: The clinical data of 37 patients with adjacent two segment CSM treated from January 2016 to December 2017 were retrospectively analyzed, including 15 males and 22 females, aged from 43 to 69 years old with an average of 54.6 years. The patients were divided into ACDF group (group A, =17) and ACCF group (group B, =20) according to the different surgery. The operation time and intraoperative blood loss were recorded;the Cobb angle and cervical curvature in the cervical fusion segments before surgery and 1, 12 months after surgery were observed;Japanese Orthopaedic Association (JOA) score was used to evaluate the surgical efficacy, and the postoperative complications were analyzed. RESULTS: All patients were followed up for 12 to 24 months with an average of 18.5 months. Operation time and intraoperative blood loss in group A were (106.3±22.6) min, (52.2±26.4) ml, respectively, while were (115.6±16.8) min, ( 61.7±20.7) ml in group B. There was no statistically significant in operation time between two groups(>0.05);intraoperative blood loss in group B was larger than group A(<0.05). The preoperative and postoperative 1 and 12 months, cervical curvature and Cobb angle of cervical fusion segment in group A were (11.28±1.40)°, (17.56±1.90)°, (16.64±1.80)° and (4.93±4.20) °, (9.44±2.60)°, (9.25±2.80)°, respectively, and in group B were (10.59± 1.20)°, (16.26±2.10)°, (15.76±2.50)° and (4.75±3.90)°, (7.98±2.10)°, (7.79±3.00)°. The cervical curvature and Cobb angle in all cervical fusion segments at 1, 12 months after surgery were obviously improved, and group A recovered more significantly than group B (<0.05). The JOA scores in group A were 9.46±1.70, 11.56±1.40, 14.86±1.20 before operation and 1 and 12 months after operation, and group B were 9.11±1.50, 11.40±1.30, 15.12±1.60, respectively. The postoperative JOA scores of the two groups were significantly improved (<0.05), and there was no statistically significant difference between two groups at the same time (>0.05). At the final follow up, in group A, dysphagia occurred in 2 cases, cage displacement in 1 case, and no titanium plate screw loose was found;and in group B, dysphagia occurred in 4 cases, titanium mesh collapse in 2 cases, titanium plate screw loose in 1 case. CONCLUSION Two types of anterior cervical decompression and fusion for the treatment of two segment cervical spondylotic myelopathy can effectively decompress and improve the Cobb angle and cervical curvature of the affected vertebra. The ACDF surgical procedure can directly removethe compressive thing at intervertebral level, which will lead to little vertebral body damage and favorably recovered cervical curvature. The ACCF surgical procedure has a large operation space, which can easily remove the posterior vertebral osteophyte and the calcified posterior longitudinal ligament. Long-term follow-up shows that ACDF and ACCF have good surgical procedures, mature technology, and close efficacy.

OBJECTIVE: To explore the clinical efficacy of C expanded half lamina excision combined with unilateral open door laminoplasty for multiple segmental cervical spinal cord compression syndrome. METHODS: The clinical data of 58 patients with multiple segmental cervical spinal cord compression syndrome underwent surgical treatment between September 2014 and May 2018 were retrospectively analyzed. There were 34 males and 24 females with a mean age of 64.4 years old (ranged from 46 to 78 years old). Among them, 28 cases received the surgery of C expanded half lamina excision combined with C-C unilateral open-door laminoplasty (improvedgroup), and 30 cases received a single C-C unilateral open-door laminoplasty (traditional group). Operation time, intraoperative blood loss, complications including C nerve root palsy and axial symptoms were compared between two groups. To evaluate the situation of the imaging indicators by measuring the space available for the spinal cord through cross sectional MRI of cervical spine at the narrowest segment of C (including intervertebral disc levels of C). Pre- and post-operative Japanese Orthopedic Association(JOA) score, Neck Disability Index(NDI) score, and improvement rate of neurological function, were recorded and analyzed between the two groups. RESULTS: All the patients were followed up for 12 to 18 months with an average of(14.5±1.8) months for improved group and (14.5±1.9) months for traditional group, and no significant difference was found between the two groups (>0.05). There was no significant difference in intraoperative blood loss and C nerve root palsy between the two groups (>0.05). The operation time (119±10) min vs (126±12) min and axial symptoms 7.1%(2/28) vs 26.6%(8/30) was significant difference between the two groups (<0.05). Preoperative and postoperative space available for the spinal cord of C was (93.61±9.02) mm and (153.50±12.76) mm respectively, which was obtained obvious improvement in all patients(<0.05). At the final follow up, JOA scores of improved group and traditional group were 14.36±1.70 and 14.03±1.82 respectively, and NDI scores were 10.36±2.55 and 12.47±3.46 respectively, there was significant difference between two groups (<0.05). However, there was no significant difference between two groups for the improvement rate (68.36±0.12)%VS (65.01±0.12)%of neurological function(>0.05). CONCLUSION C expanded half lamina excision combined with unilateral open-door laminoplasty is an effective method to treat multiple segmental cervical spinal cord compression syndrome, for it can not only fully relieved spinal cord compression, but also achievedgood effect in preventing complications such as axial symptoms by reducing stripping of muscles from C2 spinous process.
