  • RESECTION OF SPINAL TUMOR AND RECONSTRUCTION OF SPINAL STABILITY

    OBJECTIVE: Both primary and metastatic tumor of spine can influence spinal stability, spinal cord and nerves. The principles of dealing spinal tumor are resection of tumor decompression on spinal cord and reconstruction of spinal stability. METHODS: Since Aug. 1993 to Oct. 1996, 15 cases with spinal tumor were treated, including 4 primary spinal tumor and 11 metastatic tumor. Tumor foci were mainly in thoracic and lumbar spine. Graded by Frankel classification of spinal injuries, there were 1 case of grade A, 1 of grade B, 3 of grade C, 5 of grade D and 5 of grade E. Tumors of upper lumbar spine and thoracic spine were resected through anterior approach. Posterior approach also was adopted once posterior column was affected. Tumors of lower lumbar spine were resected by two-staged operation: firstly, operation through posterior approach to reconstruct spinal stability: secondly, operation through anterior approach. After resection of tumor, the spines were fixed by Kaneda instrument, Steffee plate or Kirschner pins. To fuse the spine, bone grafting was used in benign tumor and bone cement used in malignant tumor. RESULTS: Except one patient died from arrest of bone marrow, the others were followed up for 3 to 20 months. Postoperatively, 11 patients could sit up on one foot with the help of body supporter, and 9 patients could walk in two weeks under careful monitoring. There was no exacerbation of symptom and failure of fixation. The function of spinal cord was improved: 1 case from grade B to grade E, 1 from A to C, 2 from C to E and 4 from D to E. CONCLUSION: The spine can be reconstructed for weight bearing early by internal fixation. The symptom can be relieved and the nervous function can be improved by resection of tumor and decompression.

  • ANALYSIS OF SPINAL INJURIES IN WENCHUAN EARTHQUAKE

    Objective To analyze the spinal injury in Wenchuan earthquake and to investigate its cl inical features. Methods Data of 146 patients in Wenchuan earthquake with spinal injuries (79 males, 67 females; aged 11-88 years old, average 51 years old) were collected and analyzed epidemiologically. Two patients under 16 years of age, 15 patients withthe fractures of spinous process, transverse process or vertebra lamina, 1 patient with spinal fractures of type A2 according to AO classification but no corresponding type in Denis classification, and 9 patients with upper cervical injuries were excluded. The remaining 119 patients were divided into two groups according to their age: group A in which 78 patients were under 60 years of age, including 40 males and 38 females aged 18-58 years old (average 41 years old), and group B in which 41 patients were 60 years of age or above, including 24 males and 17 females aged 60-88 years old (average 71 years old). Analyses for the two groups were compared. Results The leading causes of spinal injuries were fall from high places (27.40%) and crush by heavy objects (67.81%). According to Denis classification, the major types of spinal injuries were burst fracture (54.62%) and compression fracture (33.61%). Serious nerve injury, defined as grade A, B and C in ASIA neurological function assessment, occurred in 31.51% of patients. The most common injured site was in thoracic or lumbar vertebrae (78.77%), and 52.74% of patients had combined injuries, among which the fractures of l imb (30.14%) and rib (19.86%) were the most common. Multilevel spinal fractures happened to 22.60% of patients. Comparative analysis revealed the rate of injury caused by fall from high places in group A (34.62%) was much higher than that in group B (12.20%). The commonest type of fracture in group A was burst fracture (58.97%), and it was compression fracture in group B (48.78%). The rate of serious nerve injury in group B (24.39%) was much lower than that in group A (44.87%). The rate of combined injury and multilevel vertebral body injury in group B was 70.73% and 39.02%, respectively, which was much higher than that in group A (combined injury 43.59%; multilevel vertebral body injury 21.79%). There were significant differences between two groups in all the indicators derived from cl inical data (P lt; 0.05). Conclusion In Wenchuan earthquake, the leading causes of spinal injuries are fall from high places and crush by heavy objects, the major types of fracture are compression fracture and burst fracture, and the occurrence rates of spinal injury, combined injury and multilevel vertebral body injury are high.

  • EFFECTIVENESS OF MULTIPLE JOINT ARTHROPLASTY IN TREATING LOWER LIMB JOINT DISEASE

    【Abstract】 Objective To explore the effectiveness of multiple joint arthroplasty in treating lower limb joint disease. Methods Between January 2000 and December 2007, 5 patients with lower limb joint disease (three or more joints were involved) were treated with total hip and knee arthroplasty. There were 3 males and 2 females, aged from 27 to 59 years (mean, 41.8 years). Two patients had ankylosing spondylitis and 3 had rheumatoid arthritis, whose hip and knee joints were involved. Four patients lost the ability of walking preoperatively, 1 patient could only walk with crutch. The Harris score was 24 ± 24 and the Hospital for Special Surgery (HSS) score was 28 ± 15. All patients underwent multiple joint arthroplasty simultaneously (2 cases) or multiple-stage (3 cases). Results Wounds healed by first intention in all patients. In 1 patient who had dislocation of the hip after operation, manipulative reduction and immobilization with skin traction were given for 3 weeks, and no dislocation occurred; in 2 patients who had early sign of anemia, blood transfusion was given. All patients were followed up 46-140 months with an average of 75 months. The patients could walk normally, and had no difficulty in upstairs and downstairs. The stability of the hip and knee was good, and no joint infection or loosening occurred. The Harris score was 88 ± 6 at last follow-up, showing significant difference when compared with the preoperative score (t=8.16, P=0.00); the HSS score was 86 ± 6, showing significant difference when compared with the preoperative score (t=13.96, P=0.00). Conclusion Multiple joint arthroplasty is an effective treatment method in patients with lower limb joint disease, which can significantly improve life quality of patients.

  • SURGICAL MANAGEMENT OF DURAL INJURIES AND POSTOPERATIVE CEREBROSPINAL FLUID FISTULASIN SPINAL SURGERIES

    【Abstract】 Objective To investigate the surgical management of dural injuries and postoperative cerebrospinal fluid(CSF) fistulas in spinal surgeries and to observe cl inical outcomes, since intraoperative injury of dura mater and postoperative CSF fistulas are common compl ications of spinal surgeries. Methods A retrospective research was designed and 405 patients with complete data who underwent spinal surgeries between June 2002 and March 2006 were acquired, including 298 cases of male and 107 cases of female, with the mean age of 46.2 years (ranging from 11 years to 78 years). The course of disease lasted from 3 months to 5 years. A total of 28 cases of intraoperative dural injuries and durotomies (28/405, 6.91%) were recorded, including 3 cases of cervical spinal surgery (3/152, 1.97%), 19 cases of thoracic and lumbar spinal surgery (19/239, 7.95%) and 6 cases of sacral surgery (6/14, 42.86%). CSF fistulas occurred in 6 cases of 28 patients. There were 2 cases in which no intraoperative dural injury was detected but CSF fistulas occurred after operation. The incidence of postoperative CSF fistula was 1.98% (8/405). Surgical management included closure of breach in the dura mater, oversewing every layer of the wound, bed rest and compression dressing and so on. Cl inical outcomes of surgical management were recorded. Results The average followup lasted for 1 year and 5 months (ranging from 3 months to 4 years). Preoperative symptoms remitted to different extents There were 8 cases of postoperative CSF fistula which were cured ultimately. A total of 6 cases of CSF fistulas from dorsal injuries of dura mater were treated mainly by bed rest, compression dressing and reoperations, while 2 cases of fistulas from ventral and lateral injuries of dura mater were treated by additional continuous cerebrospinal fluid drainage using a lumbar subarachnoid catheter. One case of central nervous system infection occurred and was treated successfully by multi-discipl inary disposal. Conclusion Timely and correct surgical intervention and postoperative management can help to heal dural injuries in spinal surgeries and can prevent occurrence of postoperative CSF fistulas.

  • Effectiveness of short fusion versus long fusion for degenerative scoliosis with a Cobb angle of 20-40° combined with spinal stenosis

    ObjectiveTo compare the effectiveness of decompression and short fusion or long fusion for degenerative scoliosis (DS) with a Cobb angle of 20-40° combined with spinal stenosis.MethodsThe clinical data of 50 patients with DS who were treated with decompression combined with short fusion or long fusion between January 2015 and May 2017 were retrospectively analysed. Patients were divided into long fusion group (fixed segments>3, 23 cases) and short fusion group (fixed segments≤3, 27 cases). There was no significant difference in gender, age, disease duration, and preoperative visual analogue scale (VAS) score of leg pain, Oswestry disability index (ODI), thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), pelvic incidence (PI), pelvic title (PT), and sacral slope (SS) between the two groups (P>0.05); however, the VAS score of low back pain, Cobb angle, and sagittal vertical axis (SVA) in long fusion group were significantly higher than those in short fusion group (P<0.05), and the lumbar lordosis (LL) was significantly lower than that in short fusion group (t=2.427, P=0.019). The operation time, intraoperative blood loss, fluoroscopy times, hospital stay, and complications were recorded and compared. The VAS scores of low back pain and leg pain and ODI score were used to evaluate the clinical outcomes before operation and at last follow-up. X-ray films of the whole spine in standard standing position were taken before operation, at 6 months after operation, and at last follow-up, and the spino-pelvic parameters were measured.ResultsThe operation time, intraoperative blood loss, and fluoroscopy times in the short fusion group were significantly less than those in the long fusion group (P<0.05); there was no significant difference in hospital stay between the two groups (t=0.933, P=0.355). The patients were followed up 12-46 months with an average of 22.3 months. At last follow-up, the VAS scores of low back pain and leg pain and ODI score significantly improved when compared with those before operation (P<0.05). Except for the improvement of VAS score of low back pain (t=8.332, P=0.000), the differences of the improvements of the other scores between the two groups were not significant (P>0.05). The Cobb angle, SVA, TLK, and PT significantly decreased, while SS and LL significantly increased in the long fusion group (P<0.05), while the Cobb angle and PT significantly decreased and SS significantly increased in the short fusion group at last follow-up (P<0.05). There was no significant difference in spino-pelvic parameters between the two groups at 6 months after operation and at last follow-up (P>0.05). The improvements of Cobb angle, SVA, LL, PT, and SS in the long fusion group were significantly higher than those in the short fusion group at last follow-up (P<0.05). There was no perioperative death in both groups. The incidence of complications in the long fusion group was 34.8% (8/23), which was significantly higher than that in the short fusion group [11.1% (3/27)] (χ2=4.056, P=0.034).ConclusionThe DS patients with the Cobb angle of 20-40°can achieve satisfactory clinical outcomes and improve the spino-pelvic parameters by choosing appropriate fixation levels. Short fusion has less surgical trauma and fewer complications, whereas long fusion has more advantages in enhancing spino-pelvic parameters and relieving low back pain.
