Article: [Application of Bioflex dynamic stabilization system in treating multi-segment lumbar degenerative disease].[show abstract] [hide abstract]
ABSTRACT: To explore the value of application of Bioflex dynamic stabilization system in treating multi-segment lumbar degenerative disease. Clinical datas of 13 patients with multi-segment lumbar degenerative disease (8 males and 5 females,ranging in age from 51 to 72 year with an average of 65.0) were retrospectively analyzed between April 2008 and May 2009. The involved area included L3-S1 in 7 cases, L2-S1 in 3 cases, L3-L5 in 1 cases, L4-S1 in 2 cases. All patients underwent decompression, dynamic stabilization with Bioflex system, according to the severity of degenerative disc with/without interbody fusion. The clinical effects were evaluated by VAS, ODI. ROM and fusion segments were also observed. The mean follow up period was 19.5 months (from 12 to 26 months). The mean operative time was 183.4 min (from 90 to 240 min) and the mean volume of blood loss was 610.2 ml (from 400 to 1 220 ml). The mean VAS score was 7.8 +/- 1.3 preoperatively, 2.3 +/- 0.9 postoperatively and 2.1 +/- 0.8 at the last follow up. The average ODI was (60.50 +/- 4.40)% preoperatively, (17.80 +/- 2.10)% postoperatively and (16.20 + 2.40)% at the last follow up. The VAS and ODI significant improved in postoperatively (P < 0.05), and there was no statistical difference between postoperative and last follow up (P > 0.05). ROM of whole lumbar and non-fused segment showed obviously decreased and adjacent segment showed insignificant increased. The fusion rate of interbody fusion level was 95.0% (19/20). The preliminary clinical results show the Bioflex system combined with intebody fusion is a safe and effective technique in treating multi-segment lumbar degenerative disease.Zhongguo gu shang = China journal of orthopaedics and traumatology 04/2011; 24(4):286-9.
Article: [Clinical study of short-course chemotherapy combined with radical operation in retreating spinal tuberculosis].[show abstract] [hide abstract]
ABSTRACT: To investigate clinical outcome of short-course chemotherapy in retreating spinal tuberculosis after radical operation. Forty-six retreating patients with spinal tuberculosis were included in this series, 29 males, 17 females with the age from 27 to 61 years (average of 43.7 years). All patients were treated with radical operation and short-course anti-tuberculous chemotherapy from March 2005 to March 2008. The tuberculous focus located thoracic spine in 17 cases, thoracic-lumbar in 13 and lumbosacral vertebrae in 16 cases. Of them, 5 cases had sinuses of tuberculosis and 7 cases had incomplete palsy in lower limbs (Frankel C-D). CT or MRI showed obvious sequestra, cold abscess within spinal focus. Surgical procedures including debridement, auto-bone grafting, and one-stage internal fixation, was performed at the 4 to 6 weeks after chemotherapy. Chemotherapy regimes were 3HRZ/6-9HRE in majority of patients. Clinical effect and focus healing were evaluated at follow-up period. Tuberculous symptoms and local pain of vertebral volume were obvious in all patients before chemotherapy,with average ESR 65.3 mm/h and average CRP 37.4 mg/L. After 4-6 weeks chemotherapy, tuberculosis symptoms and vertebral pain improved in all patients, and the average ESR decreased to 38.3 mm/1h, the average CRP decreased to 17.2 mg/L. Two to three months after operation, tuberculous symptoms and local pain relived in all patients,ESR and CRP became normal in 37 cases. Six to twelve months after operation, bonegraft complex in each patient became stable and there were no instrument loosening or deformity correction loss. Six patients with incomplete palsy recovered and 1 case improved from Frankel C to D grade. Focus healing was achieved in 44 cases (95.7%) after short-course chemotherapy (3HRZ/6-9HRE), and there were no resurgence in 2 to 4 years follow-up period. Drug fast 2 cases for RFP+INH cured at the 15 months after chemotherapy. Removed tubercular focus for the treatment of retreating spinal tuberculosis can improve clinical effect and shorten chemotherapy course.Zhongguo gu shang = China journal of orthopaedics and traumatology 07/2010; 23(7):491-4.
Article: [Variety of ESR and C-reactive protein levels during perioperative period in spinal tuberculosis].[show abstract] [hide abstract]
ABSTRACT: To investigate the clinical significance of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in the treatment of spinal tuberculosis. Sixty-seven patients (41 males and 26 females, ranging in age from 23 to 61 years) with active spinal tuberculosis in our hospital (from Mar. 2004 to Mar. 2007) were included in this study. The tuberculosis focus were located either in cervical spine, thoracic spine or in lumbar spine. After 4 to 6 weeks anti-tuberculosis chemotherapy, all the patients underwent one-stage operation (focus debridment) and auto-bone graft combined with internal fixation. Blood test for ESR and CRP were carried out at different times before and after operation. The average ESR was (79.4 +/- 35.6) mm/h, and the average CRP was (44.3 +/- 17.5) mg/L before chemotherapy, indicating active tuberculosis focus. After 4 to 6 weeks chemotherapy, the average ESR was (45.3 +/- 21.0) mm/h,and the average CRP was (26.7 +/- 11.8) mg/L, the differences were statistically (P < 0.05), and the clinical symptoms of spinal tuberculosis relieved in all patients. Four weeks after operation, the average ESR dropped to (42.8 +/- 16.5)mm/h, the average CRP dropped to (23.8 +/- 10.0) mg/L statistically (P < 0.05). Eight weeks after operation, the average value of ESR and CRP were at normal level in 47 cases, indicating inactive tuberculosis focus. Focus healing was achieved in 65 patients after short-term chemotherapy. The level of ESR and CRP are high in active spinal tuberculosis and low when focus controlled. ESR and CRP are reliable parameters in evaluation the treatment and prognosis of spinal tuberculosis.Zhongguo gu shang = China journal of orthopaedics and traumatology 03/2010; 23(3):200-2.
