Abstract
This study was conducted on 30 patients with lumbosacral radiculopathy. All patients were subjected to transforaminal epidural steroid injection and were followed up for 3 months. They were assessed clinically and functionally pre-injection and twice post-injection (1 and half month and 3-month post-injection).
Patients were subjected to full medical history taking, full physical and neurological examination with emphasis on special tests e.g. (Straight leg raising test, Contralateral straight raising test, Femoral nerve stretch test, Sacroiliac joints test).
Regarding demographic and clinical data, the study included 15 men and 15 women. Their ages ranged from 22 to 65 years with a mean of 41 ± 13.23 years. Disease duration ranged from 0.43 to 60 months with a mean of 6.07 (1 - 18) months.
Our results revealed:
1. A highly statistical significant difference regarding central LBP, SIJ pain, tingling & numbness; SLR; and CSLR between pre-injection visit and 1st visit post-injection (p<0.01) , a statistically significant difference regarding FNS test (p<0.05) and there was no statistically significant difference regarding SIJ (p>0.05).
2. A highly statistical significant difference regarding central LBP, tingling & numbness; SLR; and CSLR between pre-injection visit and 2nd visit post-injection (p<0.01), a statistically significant difference regarding sacroiliac pain (p<0.05) and there was no statistically significant difference as regards femoral nerve stretch test and SIJ test (p>0.05).
3. VAS and ODI scores significantly reduced in the 1st visit post-injection compared to pre-injection visit (p-value <0.01).
4. VAS and ODI scores statistically significant reduced in the 2nd visit post-injection compared to the pre-injection visit.
5. Significant positive correlation between disease duration and each of VAS score and ODI score pre-injection as well as post-injection.
6. Significant positive correlation between VAS and ODI pre-injection and post injection.
In conclusion, steroid injection treatment resulted in a significant improvement of pain intensity and reduction in functional impairment after one month of treatment and after a three month follow up from baseline. Steroid injection had the highest functional improvement that was significantly associated with pain control, especially in patients with shorter disease duration.
