Abstract

Background: dorsal spine intervertebral disc prolapse (IVDP) not a very common entity compared with cervical & lumbar region usually treated surgically.
Patients & method: 22 patients studied in the specialized surgical hospital neurosurgical department from Jan 2002 till Jan. 2006. the study included age, gender, cases. clinical features, diagnoses & surgical management.
Results: 22 patients were studied 76% of the patients are at the age of 30-60 with slight male predominance, all diagnosed by MRI & or CT scan, all managed surgically by laminectomy the results are compared with other studies.
Conclusion: posterior thoracic laminectomy at the dorsal region is a safe, simple procedure with good results if done early & meticolous.

Abstract

Recurrent intervertebral disc prolapsed (RDP) is a major cause of poor result after lumbar discectomy surgery. The aim of current study is to assess risk factors of recurrent disc prolapse in Iraqian population in Hilla teaching hospital from 2002-2013. The study reviewed 40 patients with recurrent disc prolapsed and 100 patients without recurrence retrospectively. To evaluate possible risk factors for herniation recurrence A clinically significant recurrent herniation was defined as a disc herniation causing lower limb pain (sciatica) and (MRI) evidence of disc material at the same level of the previous surgery. Other 100 patients without recurrence were used just for compares to identify possible risk factors for recurrent RDP. There was important variation between groups with and without RDP in sex, smoking, height, weight and occupational characteristic. By putting these differences in logistic regression analysis, it showed that gender (male), height, heavy workers and heavy smoker could expected in lumbar disc prolapsed recurrence(RDP). Taking into consideration sex, heavy smoking and heavy workers as predictors of recurrent RPD, surgeons should advice their patients to limit hard work and put away smoking especially in tall and male ones to prevent RDP recurrence.

Abstract

Abstract The intervertebral disc is an avascular tissue, and penetration of antibiotics occurs by passive diffusion. Cefotaxime penetration has not been well studied. The aim is to investigate the penetration of cefotaxime into the intervertebral disc removed from patients undergoing discectomy. Twenty-six patients undergoing discectomy were recruited for this study. They were given one gram of cefotaxime intravenously as a prophylactic antibiotic. Cefotaxime was extracted from nucleus pulposus and serum and analyzed using an HPLC method with cefuroxime axetil as internal standard. Cefotaxime penetrated into all the 26 samples of nucleus pulposus resulting in a mean concentration of 0.66±0.13 µg/gm. The mean serum concentration at time of disc removal was 13.61±3.54 µg/ml. The concentration in 16 samples were below the minimum inhibitory concentration against Staph. aureus with an average of 0.27±0.03 µg/g. There is a statistically significant correlation between time after intravenous cefotaxime administration and its concentration in the nucleus pulposus. The greater increase is in the third hour after administration. Factors like age, body weight, gender, number of associated diseases and surgical history did not seem to affect nucleus pulposus cefotaxime concentration. In conclusion, cefotaxime can penetrate into the nucleus pulposus but its concentration is relatively low. This concentration has a strong positive correlation with time after cefotaxime intravenous administration. Cefotaxime, therefore, needs to be given at least two hours before disc removal, with re-dosing immediately before operation to maintain high serum concentration.
