“…In addition, the L5 dermatome may vary among patients. The skin site tested in this study was the medial dorsal foot, which was regarded as the L5 dermatome in a comprehensive study combining clinical symptoms, electromyography, and imaging and surgical findings 20 . However, the medial dorsal foot may not be the L5 dermatome in a few patients.…”

Misdiagnosis of symptomatic lumbar lateral stenosis (LS) may result in an unfavourable prognosis after surgical treatment. This study investigated the diagnostic accuracy of a standardised qualitative sensory test (SQST) in the detection of symptomatic LS in patients who had degenerative spinal disorders involving the L5 spinal nerve. We prospectively identified 75 patients, of which 60 met the inclusion criteria. Lateral recess stenosis at the L5 level or foraminal stenosis at the L5/S1 level on MRI was identified and graded by a neurosurgeon blinded to any clinical information. The reference criteria for the diagnosis of symptomatic LS were grade III LS on MRI and relevant clinical symptoms. Cutaneous sensory functions of the L5 dermatome on the symptomatic side were evaluated using the SQST. Each item of the SQST showed a satisfactory performance in the diagnosis of LS (sensitivity = 0.455–0.727, specificity = 0.868–1.0). A stepwise selection model identified low-strength von-Frey, high-strength von-Frey, and vibration as the most accurate predictors of symptomatic LS with an area under the receiver operating characteristic curve of 0.9563 (95% confidence interval = 0.9003–1.0). In combination with MRI, the SQST is a promising diagnostic tool for detecting symptomatic LS involving L5 nerve roots.

“…The symptoms occur in a specific place. Patients experience problems with functioning of the root forming the sciatic nerve, and pinpointing the location of the symptoms can help in evaluating the extent of damage (Faleiros 2009). Pathology of the intervertebral disc is most commonly a cause of spinal pain, though abnormalities may occur also in ligaments, muscles and tendons.…”

Summary:The aim of this article is to review current reports pertaining the effects of treating patients with diagnosed degenerative disc disease in the lumbosacral section of the spine. Materials and methods: the method of descriptive analysis was used. The research was conducted on the basis of materials from MEDLINE and EMBASE databases from the last ten years. The cases of patients with sciatic neuritis caused by degenerative disc disease undergoing conservative treatment, and similar group of patients treated surgically, were analysed. Conclusions: Conservative treatment lowers the intensity of pain, but does not improve the functional abilities of the spine. Surgical treatment gives good and quick therapeutic results, but its long-term effects do not seem better than in the case of conservative treatment. Moreover, surgical treatment may result in serious complications. In rare cases the condition results in a severe impairment of motor functions in legs and sphincter paralysis. Such patients should undergo immediate surgical treatment.
