Treatment of Sciatica and Lumbar Radiculopathy with an Intervertebral Foramen Opening Protocol: Pilot Study in a Hospital Emergency and In-patient Setting.

AIMS: Perform a pilot study of a static nerve root foramen opening protocol for lumbar radiculopathy from disc hernia in an emergency hospital setting to establish if patients could execute the protocol, consistency would occur across outcomes, superior outcomes would occur in the experimental group, and if the protocol would be safe. METHODS: Patients with sciatica arrived of their own volition at the local emergency hospital department, were admitted for care and were randomized into two groups: 1) control (n = 10): forward bending, walking, and medication; and 2) experimental (n = 10) as control subjects, plus a static lumbar foramen opening protocol using flexion and contralateral lateral flexion (side-lying). Outcomes were back and leg pain (i.e. visual analog scale), disability (i.e. EuroQol5D5L and Oswestry) and straight leg raise. RESULTS: At admission, the baseline outcome variables between groups were not significantly different. All patients had moderate or large disc hernias on MRI and 75% had neurological deficits in electrophysiology. At discharge, patients in the experimental group were significantly better (p ≤ .05) than controls in all outcomes. Statistical analysis of the outcomes produced greater significance, effect sizes and minimal clinically important differences in the experimental group. Patients in the experimental group consumed less medication than control patients (21% versus 79%), including less than half the opioids (tramadol). No adverse responses occurred. CONCLUSIONS: Patients could perform the protocol and superior outcomes occurred, with no adverse effects. The data support more detailed study of therapeutic efficacy, days in hospital, costs, conversion to surgery, and medication consumption, including opioids.

Preoperative Predictors of Better Long-term Functional Ability and Decreased Pain Following LSS Surgery: A Prospective Observational Study with a 10-year Follow-up Period.

STUDY DESIGN: A prospective observational 10-year follow-up study. OBJECTIVE: This study aimed to examine preoperative predictors for better surgical outcomes in patients with lumbar spinal stenosis (LSS) 10 years after surgery. SUMMARY OF BACKGROUND DATA: LSS is a leading cause of low back surgery in patients older than 65 years. Limited data are available for predictors of long-term surgical outcomes in patients with LSS. METHODS: At the baseline, 102 patients with LSS underwent decompressive surgery, and 72 of the original study sample participated in a 10-year follow-up study. Study patients filled out a questionnaire preoperatively, and follow-up data were collected at 3 months, 6 months, 1 year, 2 years, 5 years, and 10 years postoperatively. Surgical outcomes were evaluated in terms of disability with the Oswestry Disability Index (ODI) and pain with the visual analog scale (VAS). Predictors in the models were nonsmoking status, absence of previous lumbar surgery, self-rated health, regular use of painkillers for symptom alleviation, and BMI. Statistical analyses included longitudinal associations, subgroup analyses, and cross-sectional analyses. RESULTS: Using multivariate analysis, statistically significant predictors for lower ODI and VAS scores at 10 years were nonsmoking status, absence of previous lumbar surgery, better self-rated health, and regular use of painkillers for <12 months. Patients who smoked preoperatively or had previous lumbar surgery experienced more pain and disability at the 10-year follow-up. CONCLUSION: These study results can enhance informed decision-making processes for patients considering surgical treatment for LSS by showing preoperative predictors for surgical outcomes up to 10 years after surgery. Smokers and patients with previous lumbar surgery showed a decline in surgical benefits after 5 years. LEVEL OF EVIDENCE: 3.
