Background Successful management of workers on sick leave due to low back pain by the general physician and physiotherapist depends on reliable prognostic information on the course of low back pain and work resumption. Methods Retrospective cohort study in 194 patients who were compensated because of chronic low back pain and who were treated by a physiotherapy functional restoration program. Patient-reported and clinician based prognostic indicators were assessed at baseline before patients entered the functional restoration program. We investigated the predictive value of these indicators on work status at 6 months. Relationships were studied using logistic regression analysis in a 2-step bootstrap modelling approach and a nomogram was developed. Discrimination and calibration of the nomogram was evaluated internally and the explained variation of the nomogram calculated. Results Seventy percent of workers were back to work at 6 months. We found that including duration of complaints, functional disability, disc herniation and fear avoidance beliefs resulted in the ''best'' prognostic model. All these factors delayed work resumption. This model was used to construct a nomogram. The explained variation of the nomogram was 23.7%. Discrimination was estimated by the area under 383-397 DOI 10.1007/s10926-007-9084-1 123 the receiver operating characteristic curve and was 0.76 and for calibration we used the slope estimate that was 0.91. The positive predictive values of the nomogram at different cut-off levels of predicted probability were good. Conclusions Knowledge of the predictive value of these indicators by physicians and physiotherapists will help to identify subgroups of patients and will thus enhance clinical decision-making.

Background:The enSpire TM interventional discectomy system is a new device for treating percutaneous disc decompression (PDD). The outcomes of using the enSpire TM for lumbar disc herniation have not been previously reported. The aim of this study was to determine the clinical effectiveness and safety of the enSpire TM interventional discectomy system for lumbar disc herniation with radiating pain. Methods: Twelve patients with lumbar disc herniation with radiating leg pain were enrolled in the study. All patients received PDD using enSpire TM . Numeric rating scale (NRS) scores for pain and Oswestry Disability Index (ODI) scores were obtained initially and after 1 and 3 months. The patients were divided into 2 groups: Group 1, in which the NRS score improved by more than 50% at 3 months after procedure, and Group 2, in which the NRS score remained the same or improved by less than 50%. Results: After PDD using the enSpire TM , the NRS scores decreased from 6.9 ± 1.2 to 2.8 ± 2.7; and ODI scores decreased from 25.8 ± 4.6 to 18.2 ± 5.5. No statistical differences occurred between Group 1 (n = 8) and Group 2 (n = 4) except in the duration of prior illness. Conclusions: The enSpire TM interventional discectomy system is effective and safe over the short-term, minimally invasive, and easy to use. (Anesth Pain Med 2017; 12: 72-76)

“…Semiconductor lasers will make it quite convenient to channel light through optical fibers that are about 0.1 mm in diameter. In recent years, it has become increasingly common to use fiberdelivered laser light to assist lipolysis, [1][2][3] percutaneous laser disk decompression, [4][5][6] and other ablation therapy treatments. Semiconductor lasers do not require dangerously high voltages and their total volumes are relatively compact, making them quite convenient for physicians to carry.…”

High temperature heat source generation with quasi-continuous wave semiconductor lasers at power levels of 6 W for medical use

et al. 2014

Abstract. We investigate a technology to create a high temperature heat source on the tip surface of the glass fiber proposed for medical surgery applications. Using 4 to 6 W power level semiconductor lasers at a wavelength of 980 nm, a laser coupled fiber tip was preprocessed to contain a certain amount of titanium oxide powder with a depth of 100 μm from the tip surface so that the irradiated low laser energy could be perfectly absorbed to be transferred to thermal energy. Thus, the laser treatment can be performed without suffering from any optical characteristic of the material. A semiconductor laser was operated quasi-continuous wave mode pulse time duration of 180 ms and >95% of the laser energy was converted to thermal energy in the fiber tip. Based on two-color thermometry, by using a gated optical multichannel analyzer with a 0.25 m spectrometer in visible wavelength region, the temperature of the fiber tip was analyzed. The temperature of the heat source was measured to be in excess 3100 K. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.
