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 study the changes of anterior soft tissue swelling after anterior cervical subtotal corpectomy, titanium mesh fusion and internal fixation. METHODS: From November 2015 to July 2018, 151 patients with cervical spondylotic myelopathy were treated with anterior single corpectomy, titanium mesh fusion and internal fixation, including 109 males and 42 females, aged 44 to 81 (59.77±8.34) years. Through postoperative follow up observation, the C RESULTS: All patients were followed up for 15 to 40(28.00±3.52) months. One week after the operation, the swelling of anterior soft tissue reached the peak, and then decreased. At 8 months after the operation, the swelling of anterior soft tissue on C CONCLUSION Anterior subtotal cervical corpectomy, titanium mesh bone graft fusion and internal fixation can cause swelling of the anterior soft tissue. One week after operation, we should pay more attention to the aggravation of the swelling of the anterior soft tissue to avoid the occurrence of dysphagia, respiratory obstruction, asphyxia and other complications.

OBJECTIVETo investigate the diagnosis and surgical techniques of intramedullary hemangioblastoma of the cervical spinal cord.

METHODSMR imaging and the methods and results of surgery were analyzed in 21 patients.

RESULTSThe tumors were divided into three types on MR imaging. Syringeal type, where the tumor varied in size and was accompanied by syringobulbia and syringomyelia; Cystic type, where the tumor presented as a cyst with a small mural node; and Solid type, where the tumor was revealed as a huge solid mass. All tumors were totally removed and diagnosis was confirmed by histological study. Post-operative neurological status was improved in 20 patients and aggravated in 1.

CONCLUSIONSThe localization and the nature diagnosis of the tumor can be made by cervical MR imaging. Operative methods vary with tumor types. It is the most important that the tumor is dissected along the right interface and removed after devascularization.

OBJECTIVETo research the clinical application of lower cervical pedicle screw fixation procedure.

METHODSFrom September 2011 to July 2013,32 patients underwent posterior pedicle screw-rod system fixation were retrospective analyzed includinig 20 males and 12 females with an average age of 56.4 years old ranging from 21 to 78 years. Among them, 10 patients were traumatic cervical spinal injury, 9 patients were cervical spinal canal tumors, 7 cases were posterior longitudinal ligament ossification of cervical vertebrae, 6 cases were multiple segmental cervical spondylopathy. Preoperatively, X-ray, computed tomography, magnetic resonance imaging and magnetic resonance angiography of the vertebral artery were performed in all patients. After the operation and during the follow-up,X-ray and computed tomography were performed to confirm the pedicle screw position. The accuracy of the pedicle screw placement was evaluated by 4 grades classification from Lee. The spinal cord function was assessed by ASIA impairment scale for traumatic patients and JOA score for non traumatic patients.

RESULTSTotally 144 pedicle screws performed on 32 patients from C3 to C7 involving 132 screws of grade 0,5 screws of grade 1,5 of screws grade 2 and 2 screws of grade 3 according to postoperative CT. There were 12 screws penetrating the pedicle cortex including 8 screws at lateral,2 screws at caudal, 1 screw at medial and 1 screw at cranial. The follow-up time was 12 to 33 months with an average of (21.0±1.5) months. The spinal cord function was not improved in 6 complete cervical spinal cord injury patients,but their paraplegic level descended 1 to 3 segments. Four incomplete cervical spinal cord injury patients' ASIA impairment scale was increased by 1 to 2 grades in average. The JOA score of 22 atraumatic patients increased from preoperative 11.5±0.8 to 15.9±0.6 of postoperative at 6 months (P<0.01). There were no screw loosening,screw pullout and screw-rod breakage.

CONCLUSIONThe lower cervical pedicle screw fixation can provide excellent 3D stability of the vertebral column. The operation risk and Complication could be minimized by adequate preoperative evaluation for appropriate cases and individual pedicle screw placement. It deserved the clinical expansion.

OBJECTIVETo evaluate the effects of cervical vertebrae degeneration on traumatic cervical cord injury.

METHODSFrom January 2009 to December 2010, 24 patients with cervical cord injury without obvious fractures and dislocations were treated with operation, and their data were retrospectively analyzed. Among them, 16 males and 8 females, aged from 46 to 70 years old with an average of 59.1 years. Patients were divided into light degeneration group (6 cases), moderate degeneration group (10 cases) and severe degeneration group (8 cases), according to the preoperative degenerative degree of cervical vertebrae. Preoperative neurological dysfunction and postoperative neurological recovery were compared according to the JOA scores of Japanese Orthopaedic Society; quality of life were evaluated according to SF-36 scale (36-item Short Form Health Survey, SF-36).

RESULTSAll patients were followed up from 4 to 16 months with an average of 12 months. The JOA score of light, moderate, severe degeneration group were 12.1 +/- 1.5, 10.3 +/- 1.8, 7.3 +/- 1.0, respectively; and were respectively increased to 16.3 +/- 1.0, 15.3 +/- 1.4, 13.0 +/- 2.3 at the 3 months after operation. Postoperative JOA score showed the improvement rate of mid-long-term neurological level was light degeneration group (89.8%) > moderate degeneration group (76.6%) > severe degeneration group (58.8%). The results of preoperative SF-36 scale showed light degeneration group > moderate degeneration group > severe degeneration group; there was significant difference in comparison of two groups (P < 0.05 ).

CONCLUSIONCervical degeneration is an important pathologic basis and risk factor in traumatic cervical cord injury, and the degenerative degree will directly influence the injury degree and prognosis of neurological function, the clinical relationship between them should be sufficiently paid attention to.

OBJECTIVETo study the outcomes of surgeries for acute central cervical spinal cord injury without cervical spine fracture or dislocation in young and middle-aged patients.

METHODSThe clinical data of 58 young and middle-aged patients with acute central cervical spinal cord injury treated in our hospital between August 2005 and August 2009 were analyzed retrospectively. Of these patients, 33 (24 males and 9 females) received surgical treatment and 25 (17 males and 8 females) had conservative therapy. The ASIA grade and ASIA motor and sensory score were used for evaluation at admission and at 14 days and 1 year after the treatment. The neurological symptoms and treatment outcomes in the two groups were evaluated.

RESULTSThe proportion of patients with ASIA grade D-E and the ASIA motor and sensory scores were all significantly higher in the surgical group than in the non-surgical treatment group (P<0.05).

CONCLUSIONFor young and middle-aged patients with central cervical spinal cord injury, immediate surgery can relieve the pressure on the injured spinal cord and improve the micro-circulation to promote functional recovery of the spinal cord.
