RESUMEN
BACKGROUND: Cervical radiculopathy is a relatively common and disabling condition involving local pain in the neck region and pain that radiates into the upper limb. Recent data suggest that cervical traction may effectively reduce disability and pain, with a dose-response relationship. The main aim of this study was therefore to evaluate the mid-term effect of an intensive cervical traction protocol for patients with cervical radiculopathy on disability, and to compare the effects with those reported by non-intensive protocols in the literature. METHODS: We conducted a prospective open observational study of 36 patients referred by their general practitioner for symptoms suggestive of cervical radiculopathy. All patients underwent the same treatment: a 30-minute cervical traction protocol, twice a day, for five consecutive days. The main objective was the evaluation of disability at 3 months. We evaluated at baseline (D1), the end of the protocol (D5) and at mid-term (M3) disability, cervical pain, radiating pain, pain on motor imagery, presence of neuropathic pain and medication consumption. The primary outcome was the proportion of patients for whom the Neck Disability Index improved by more than the minimum clinically important difference of 7 points by M3. RESULTS: Thirty-six patients were included in this study. The Neck Disability Index improved by more than the minimum clinically important difference in 48.3% at M3. Mean Neck Disability Index (p < .001), mean cervical VAS (p < .001), mean radiating VAS (p < .001), and mean VAS for imagined lateral flexion and rotation (p < .002) improved significantly from D1 to D5 and from D1 to M3. Consumption of medication reduced at each time point. The proportion of patients with neuropathic pain reduced from 61.1% at D1 to 33.3% at D5 and 48.3% at M3. CONCLUSION: Disability reduced by more than the minimum clinically important difference in almost half of the participants following the intensive traction protocol. These results are encouraging and suggest that this complex condition can be treated with relatively simple methods.

OBJECTIVES: To decrease radiation exposure of patients undergoing interventional rheumatology procedures, without adversely affecting quality of care. METHODS: The radiation dose received, assessed by the dose-area product (DAP), was measured during 283 intraarticular injections performed under fluoroscopic guidance between May and July 2013. Then, three steps were taken to decrease patients' radiation exposure: a copper filter was added, the anti-scatter grid was removed, and exposure cell sensitivity was set at the highest value. DAP was measured during 158 intraarticular injections performed in 2014 with these measures in place. RESULTS: Mean DAP before optimization was 175µGray·m2 during facet joint injections (n=4) and 43µGray·m2 during hip injections but was less than 20µGray·m2 for injections into the shoulders (15.7µGray·m2), ankles (7.7µGray·m2), wrists (3.7µGray·m2), and fingers (3.3µGray·m2). After optimization, DAP decreased markedly for all injection sites, by 52% (shoulders) to 87% (facet joints, 22.7µGray·m2). Decreases occurred at all three steps of the procedure, i.e., patient installation, injection, and last image hold. Exposure during facet joint injections varied from 84 (54.5-108.5) µGray·m2 when body mass index (BMI) was <25kg/m2 to 228.9 (161.3-340.4)µGray·m2 when BMI was>30kg/m2. CONCLUSION: Simple technical changes translate into large decreases in patient radiation exposure during fluoroscopically-guided injections, particularly at the facet joints and in obese patients.
