1/6. Disappearance of central pain following iatrogenic stroke.An exceptional case of long-standing central pain temporarily relieved by a focal stroke in the primary somatosensory area is reported. This case highlights the focal nature of central pain mechanisms and the possible value of selective subparietal leukotomies in the management of central pain.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/6. Unilateral calf hypertrophy seen in lumbosacral stenosis: case report and review of the literature.STUDY DESIGN: A case report of a patient with neurogenic unilateral calf hypertrophy and review of the literature are reported. OBJECTIVES: To provide further evidence that S1 radiculopathy is predisposed to develop neurogenic muscle hypertrophy. SUMMARY OF BACKGROUND DATA: Calf hypertrophy, specifically hypertrophy of the gastrocnemius muscle, is a rare but recognized presentation of S1 and less commonly L5 radiculopathies. The pathophysiology of this is incompletely understood. methods: We present a 59-year-old patient with painless progressive distal right leg weakness and calf enlargement. Electrodiagnostic studies and magnetic resonance imaging scanning were performed to evaluate the extent and cause of radicular damage as the etiology for unilateral calf hypertrophy. RESULTS: Examination and electrodiagnostic studies revealed right L5, right S1, and left L5 radiculopathies. Imaging studies demonstrated lumbar stenosis at L3-L4, L4-L5, and L5-S1 vertebral levels as well as L4-L5 and L5-S1 foraminal stenosis. After decompressive surgery the progressive nature of the patient's symptomatology halted, and he had partial resolution of his deficits. CONCLUSION: Although the patient had bilateral L5 radiculopathies, he only had hypertrophy in the distribution of his right S1 radiculopathy. This supports the hypothesis that dysfunction of the S1 nerve root or its distribution is a predisposing factor to develop neurogenic muscle hypertrophy. Furthermore, patients presenting with unilateral calf hypertrophy need a careful diagnostic evaluation for S1 radiculopathy as well as to exclude asymmetric presentation of systemic neuromuscular conditions.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/6. Inadvertent intraforaminal iliosacral screw placement despite apparent appropriate positioning on intraoperative fluoroscopy.We present the case of an intraforaminal iliosacral screw placed percutaneously with aid of C-arm using inlet, outlet, and lateral views of the pelvis. The iliosacral screw was placed above the S1 foramen on the outlet view, into the middle of S1 via the ala on the inlet view, and below the cortical shadow of the ala on the lateral view. The patient was neurologically intact postoperatively, but began to complain of severe radicular pain in the S1 distribution down to the foot within 1 week postsurgery. There was mild weakness of plantar flexion. Postoperative computed tomography scan showed that the iliosacral screw was within the S1 foramen. Because of the tangential nature of the S1 foramen, slight posterior placement of the screw into the S1 body and not into the promontory resulted in violation of the foramen despite it being above the cortical shadow on the outlet view.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/6. herpes zoster: a consideration in the differential diagnosis of radiculopathy.herpes zoster probably occurs more often than generally thought. Since it produces a radicular distribution of pain, it should be included in the differential diagnosis of radiculopathy. A case is presented in which evaluating the radicular low back pain before the characteristic rash appears was misleading. Careful history-taking concerning the exact nature of the pain and sensory changes is needed to differentiate between zoster and radiculopathy, if no rash is evident.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/6. A manual therapy approach to evaluation and treatment of a patient with a chronic lumbar nerve root irritation.The purpose of this case report is to familiarize the reader with the basic principles of the approach to manual therapy evaluation and treatment pioneered by Maitland, an Australian physical therapist. This approach involves a complete subjective examination to determine the severity, irritability, nature, and stage of the patient's complaints. In this way, the therapist may reach conclusions as to the amount and vigor of the physical examination and proceed with treatment in an analytical manner. Methodical reassessment is used to justify treatment progression. Comprehensive treatment and the rationale for this approach are discussed. Though most physical therapists are familiar with the straight-leg-raising test as a means of assessing low back pain and chronic lumbar nerve root irritation, they are often not familiar with other tests that examine neural tissues, such as the slump test. The proposed anatomical and biomechanical bases for these tests are discussed. The patient in this case study was a 50-year-old man with a physician's diagnosis of a chronic lumbar nerve root irritation. The patient was evaluated and treated in eight visits using techniques designed to evaluate neural tissues. Reassessment indicated significant symptom reduction, and the treatment was modified accordingly. Patient management, including home exercises, is discussed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
6/6. Intracranial tumor masquerading as cervical radiculopathy: a case study.physicians who treat musculoskeletal and neurologic disorders often treat patients who have paresthesias or weakness of a single extremity. Although the diagnosis is often straightforward, cases that are atypical in nature may pose a diagnostic dilemma. This report describes the case of a middle-aged man with symptoms indicative of, though not classic for, a cervical radiculopathy. An extensive investigation was unremarkable and only the eventual rapid progression of symptoms led to the diagnosis of a glioblastoma multiforme. Although this is a deadly form of brain cancer, early recognition provides the best chance for a prolonged and greater quality of life.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
