Abstract
ABSTRACT Objective: To compare the postoperative clinical course of placement of interspinous spacer with open technique (ISO) with percutaneous interspinous spacer (PIS). Methods: Quasi-experimental, longitudinal study of 42 patients with discogenic pain uncontrolled with analgesics, aged 35-55 years old, 21 women, and 21 men. Clinical history, location of pain, VAS scale before and after surgery, Oswestry Disability Index and Macnab modified scale at 6 months were used. Results: When performing quantitative analysis statistical significance (p = 0.0478, 0.0466, 0.0399) was demonstrated with Student's t test between the results according to VAS scale; in the qualitative analysis with the Oswestry index and Macnab modified scale it was demonstrated the hypothesis that the results is dependent of the surgical technique. Conclusions: According to the results, we can conclude that there is a statistically significant difference depending on the surgical technique used with respect to the rate of disability and functionality in daily life as well as in the improvement of pain symptoms.
Highlights
Chronic pain affects one quarter of the general population, averaging around 27%
In conducting a quantitative analysis of the results obtained using the visual analog scale (VAS) scale, we found a preoperative average of 8.6 points during the intense pain episode
The Student’s t test was performed to check the statistical difference between the two techniques giving us a result of p < 0.5 in all cases. (Table 3) The contingency table and the chi-squared test were used to perform qualitative analysis of the Modified Macnab scale and Oswestry Disability Index variables at 6 months following surgery, with the main question being whether or not the outcome from the placement of interspinous spacers in patients with persistent discogenic pain is dependent on the surgical technique used, with the following results: X1: 0.0172 > X°: 0.0025, supporting the assumption that scores resulting from the Macnab Modified Scale and the Oswestry Disability Index are dependent on the technique used. (Tables 4 and 5)
Summary
One quarter of patients with chronic pain, have low back pain. Lumbalgia results in costs associated with work disability and the treatment used. In this regard, approximately 30% of those suffering from low back pain in Mexico retire due to disability.[1] Discogenic pain has been defined as pain originating from the intervertebral disc itself. Approximately 30% of those suffering from low back pain in Mexico retire due to disability.[1] Discogenic pain has been defined as pain originating from the intervertebral disc itself It is not radicular and can occur in the absence of spinal deformities, instability, or signs of neural tension.
