Image processing lumbar spine to highlight the location of the herniated disc

Low back pain is a common disease. A common cause of this problem is a herniated disc in the lumbar spine. Lumbar disc herniation represents the displacement of the disc (annular fibrosis or medullary nuclei). While most cases, the pain will disappear in a few days to a few weeks; however, it can last for three months or more. Detection and diagnosis are the two most important tasks in a computer-aided diagnostic system. In this article, we use images taken from the results of the MRI imaging of the patient. Through the use of image inversion to highlight the position of degenerative discs. This result wishes to provide a simple and inexpensive diagnostic image processing method to help doctors quickly determine the degree of disc herniation, the status of lumbar discs, they can give the appropriate treatment to the patient.

Functional outcome assessment for surgical decompression of cervical spondylotic myelopathy

Background: Cervical spondylotic myelopathy (CSM) is one of the most common dysfunctions of spinal cord occurs due to degenerative changes in cervical spine disc and facet joints. It is a form of progressive spine disease including herniated disc and spinal cord stenosis which manifests as changes in gait, skilled hand movements, muscle strength, bladder dysfunction etc. Recent studies and trials have established that surgical decompression of cervical spinal is a cost-effective treatment modality which provide satisfactory functional recovery. This study aimed at the functional outcome of surgical decompression of CSM.Methods: The prospective study of 100 cases of cervical myelopathy for which decompressive surgery was done from August 2020 to August 2021. Results were analysed according to Nuricks and modified Japanese orthopedic association scoring system (MJOA).Results: Seventy one males and 29 females were included in this study with average age was 53 and average hospital stay was 3.55 days. Average pre-op Nurick score was 1.93, while score after 6 months and 1year were 1.44 and 1.15respectively. Average pre-op MJOA score was 13.63, while score after 6 months and 1 year were 14.58 and 15.74 respectively.Conclusions: The functional results of decompressive surgeries for cervical myelopathy are satisfactory. Both anterior and posterior approaches are recommended for multiple cervical myelopathy with comparable outcomes. DM and age was observed as the independent predictor for functional outcome, while, gender and level of disease got less significant predictive value.

DISC HERNIA - DIFFERENTIAL DIAGNOSTICS, OPTION OF PSEUDOTUMOROUS FLOW

Грыжа диска (ГД) является распространенным заболеванием и наносит большой вред как физическому, так и психическому здоровью пациентов, страдающих этим заболеванием. Главным этиологическим фактором заболевания служит дегенерация диска. В настоящее время общее определение грыжи межпозвонкового диска в клинической медицине довольно запутанно. В настоящее время общее определение грыжи межпозвонкового диска в клинической медицине довольно запутанно. Окончательный диагноз ГД основывается на совокупности анамнеза, клинических симптомов и результатах визуализации. Herniated disc is a common disease and causes great harm to both the physical and mental health of patients suffering from this disease. The main etiological factor of the disease is disc degeneration. Currently, the general definition of a herniated disc in clinical medicine is quite confusing. Currently, the general definition of a herniated disc in clinical medicine is quite confusing. The final diagnosis of HD is based on a combination of anamnesis, clinical symptoms, and imaging results.

TNF-ɑ Induces Methylglyoxal Accumulation in Lumbar Herniated Disc of Patients With Radicular Pain

Lumbar disc herniation (LDH) with radicular pain is a common and complicated musculoskeletal disorder. Our previous study showed that LDH-induced methylglyoxal (MG) accumulation contributed to radicular pain. The underlying mechanisms through which MG accumulates are poorly understood. In the present study, we found that both MG and tumor necrosis factor-alpha (TNF-ɑ) levels in the herniated disc of patients with radicular pain were significantly increased, and the activity of Glyoxalase 1 (GLO1), the rate-limiting enzyme that metabolizes MG, was decreased. In rats, the LDH model was mimicked by implantation of autologous nucleus pulposus (NP) to the left lumbar five spinal nerve root. The mechanical allodynia was observed in LDH rats. Besides, MG and TNF-ɑ levels were increased, and GLO1 activity was significantly decreased in the implanted NP. In cultured rat NP cells, stimulation with the inflammatory mediator TNF-ɑ reduced GLO1 activity and expression. These results suggested that TNF-ɑ-induced GLO1 activity decrease contributed to MG accumulation in the herniated disc of patients with radicular pain.

Assessing the quality of shared decision making for elective orthopedic surgery across a large healthcare system: cross-sectional survey study

Background Clinical guidelines recommend engaging patients in shared decision making for common orthopedic procedures; however, limited work has assessed what is occurring in practice. This study assessed the quality of shared decision making for elective hip and knee replacement and spine surgery at four network-affiliated hospitals. Methods A cross-sectional sample of 875 adult patients undergoing total hip or knee joint replacement (TJR) for osteoarthritis or spine surgery for lumbar herniated disc or lumbar spinal stenosis was selected. Patients were mailed a survey including measures of Shared Decision Making (SDMP scale) and Informed, Patient-Centered (IPC) decisions. We examined decision-making across sites, surgeons, and conditions, and whether the decision-making measures were associated with better health outcomes. Analyses were adjusted for clustering of patients within surgeons. Results Six hundred forty-six surveys (74% response rate) were returned with sufficient responses for analysis. Patients who had TJR reported lower SDMP scores than patients who had spine surgery (2.2 vs. 2.8; p < 0.001). Patients who had TJR were more likely to make IPC decisions (OA = 70%, Spine = 41%; p < 0.001). SDMP and IPC scores varied widely across surgeons, but the site was not predictive of SDMP scores or IPC decisions (all p > 0.09). Higher SDMP scores and IPC decisions were associated with larger improvements in global health outcomes for patients who had TJR, but not patients who had spine surgery. Conclusions Measures of shared decision making and decision quality varied among patients undergoing common elective orthopedic procedures. Routine measurement of shared decision making provides insight into areas of strength across these different orthopedic conditions as well as areas in need of improvement.

Effects of Two Different Preoperative Doses of Pregabalin on Postoperative Pain After Lumbar Disc Herniation Surgery

Background: Postoperative pain is a common and significant complication, and there are several ways to control it. In recent years, there has been a growing tendency to use pregabalin to control pain. Objectives: This study aimed to compare the effects of two different doses of pregabalin on postoperative pain after lumbar disc herniation surgery. Methods: This clinical trial study was performed on 90 patients undergoing elective herniated disc surgery in Khatam Al-Anbia Hospital of Zahedan, Iran, using random sampling. The patients were divided into three groups, including those receiving high dose pregabalin (150 mg), low dose pregabalin (75 mg), and placebo. The three groups were compared regarding postoperative pain, the received dose of analgesic, and the severity of side effects. The data were analyzed based on the Chi-square test and one-way analysis of variance using SPSS software (version 18). Results: In this study, the mean age of the patients was 43.9±6.7 years. The mean postoperative pain was significantly lower in both pregabalin groups than the placebo group (P < 0.05). Moreover, the mean postoperative pain in the high-dose pregabalin group was less than that of the low-dose group; however, the difference was not statistically significant (P > 0.05). Analgesics were needed for 8 patients (26.7%) of the low-dose pregabalin group. Furthermore, 7 patients (23.3%) of the high-dose pregabalin group and 16 patients (53.3%) of the placebo group also needed analgesics (P = 0.028). Additionally, 5 (16.7%), 8 (26.7%), and 4 (13.3%) patients in the low-dose pregabalin group, high-dose pregabalin group, and placebo group complained of side effects (P = 0.390). Conclusions: The present study showed that pregabalin significantly reduces postoperative pain and the required dose of analgesia. On the other hand, pregabalin complications are minor and can be neglected.

Spontaneous Regression of Disc Prolapse – An Underlooked Phenomena: A Case Report and Literature Review

Introduction: Intervertebral disc prolapse is a very common abnormality found in the population, that can manifest in a variety of complaints like back pain, radiculopathy, and even to the extent that it might lead to more adverse neurological deficits. Symptoms improve in majority of patients only with conservative treatment. However, some patients may require surgical intervention. In some cases, spontaneous regression of herniated disc can be seen. Thus, the interest in the phenomenon of spontaneous resorption of the herniated discs has increased, which raised the controversy regarding managing such patients. Here, we report a case of a huge lumbosacral spontaneous disc resolution at the level of L5-S1 in which clinical improvement was associated with a significant decrease in the size of a huge, herniated disc. In addition, we performed a comprehensive review of literature of all reported cases of spontaneous disc resolution to provide an updated discussion of such an underlooked phenomena. Case Report: A 53-year-old female not known to have any medical illness presented at the Neurosurgery Clinic with complaints of chronic back pain for six years which was progressing and radiating to both of her lower extremities (right more than left) and had become more intense in the last year. It was slightly relieved by simple analgesics and aggravated by sitting or lying down. There was no history of trauma, weaknesses, or sphincteric disturbances. Upon evaluation in our clinic, local exam revealed lower back midline tenderness at the level of L5-S1 vertebrae. No tenderness was observed in the paravertebral area or facets. Straight leg raising test was positive at 70º in the right side and 90º in the left, normal power, intact sensation, normal tone, and reflexes. Negative Babinski and clonus was noted in both limbs. MRI lumbar spine showed significant right paracentral L5-S1 disk prolapse indenting the thecal sac compressing the root. A full-course and effective medical treatment was initiated as the patient was never treated properly before for her back pain, along with physical therapy and regular OPD follow-ups. A follow-up MRI a year later revealed significant reduction in the size of the disk prolapse as compared to the initial imaging study. Overall, patient’s symptoms significantly improved, and she was kept on conservative management. Conclusion: To conclude, the case presented here shows the efficacy and validity of conservative management for patients who are diagnosed with a herniated disc in the absence of neurological deficits. This shows the importance of not pushing surgical treatment for patient with lumbar disc herniation without neurological deficits, each patient should receive a trial of conservative therapy and close OPD follow-ups and repeated MRI scans for further assessment of any advancement or improvement, because herniated discs can regress spontaneously. Radiological changes alone should not be the main target for assessing improvement, what matters more is clinical and symptomatic improvement. Surgical management remains an important therapeutic option for patients who failed conservative management and patients who have severe neurological deficits.

Rare Case of Lumbosacral Conjoint Root Diagnosed as Sequestered Disc by MRI: A Case Report

Introduction: Conjoint nerve root is embryological nerve root abnormality mainly affecting lumbosacral region. The atypical roots present primarily as a bifid, conjoined structure originating from a wide area of the dura. The conjoint roots are highly liable to trauma due to their size and attachment to surrounding structures. The effects of compression and entrapment are augmented in the case of having stenosis of the lateral recesses where developmental changes and disc herniations deplete the available reserve space. Conjoined nerve roots are a relatively uncommon finding but are frequently left undiagnosed on preoperative imaging studies. Misinterpretation as sequestered disc can lead to devastating results especially during limited spine approach. Case Report: A 43-year-old male patient presented with low back pain gradually progressing over the last three years. Pain was radiating to his left leg associated with tingling sensation and a mild weakness in his left foot. Clinical examination revealed normal muscle bulk and tone. Strength was full bilaterally except the mild weakness 3/5 on toe dorsiflexion of the left foot. Deep tendon reflexes were 3+ at the left knee and ankle. Plantar responses were flexor. Sensation was intact, and there was no loss of sphincters control or bladder dysfunction. A standard plain lumbosacral MRI was performed. The patient was admitted for L5/S1 discectomy. Surgical intervention was recommended, during the surgery we recognized the huge conjoint root. Adhesiolysis and discectomy was done carefully without causing any serious neural injury to the conjoint root. Clinical surgical outcome was good. Pain and tingling sensation disappeared only paresthesia over the S1 dermatome. Postoperative course was uneventful, and the patient was discharged after his neurological improvement on day 7, post operation. However, the patient complained of recurrent pain on follow-up visit and continues being followed-up. Conclusion: The conjoined nerve root anomaly diagnosis is not easy and has several points of significance. If misdiagnosed, it could be incorrectly treated as a case for a herniated disc. Neurosurgeons should consider these anomalies in their differential diagnosis. Cases of conjoined nerve root anomaly may be wrongly managed and result in wrong level of surgery with a poor outcome. Researchers conclude that the correct diagnosis of root anomalies is vital for the patient, any misinterpretation could lead to catastrophic consequences.
