Lumbar Spinal Epidural Varices Causing Acute Bilateral Lower Limb Radiculopathy: A Case Report.

CASE: A 61-year-old male patient presented with back pain and bilateral lower limb radicular pain. A Magnetic Resonance Imaging (MRI) scan of the lumbar spine was suggestive of engorged epidural veins behind the L5 vertebral body causing severe cauda equina compression. A venous Doppler scan demonstrated thrombosis of the inferior vena cava, which was identified as the primary pathology. He was started on anticoagulation, after which his radicular symptoms improved significantly. The patient was asymptomatic at the time of final follow-up at 1 year. CONCLUSION: Epidural varices can rarely present with lumbar radiculopathy mimicking an acute disk prolapse clinically and radiologically. Careful interpretation of the MRI scan will ensure proper diagnosis and avoid unnecessary surgery.

Surgical approaches to L5 corpectomy: a systematic review.

INTRODUCTION: Surgical approaches to pathologies of the L5 vertebra constitute a significant challenge. Our aim was to review the efficacy and safety of the surgical approaches to L5 corpectomy and reconstruction across the range of presenting pathology. MATERIALS AND METHODS: This systematic review was conducted according to PRISMA guidelines, and databases were searched from 1970 to January 2020. The search inclusion criteria were L5 Corpectomy AND/OR Spondylectomy AND/OR Vertebrectomy. The outcome measures studied were length of surgery, blood loss, fusion or failure of fusion/instrumentation, complications and mortality. RESULTS: Initial 36 articles were identified, and final 6 studies met our inclusion criteria. The mean reported blood loss was 2265 ml (400-4700 ml) and was higher for the two-stage posterior-anterior surgery group than the posterior-only surgery group (mean 3230 mls vs. 1260 mls) but not the operative time. All surgical approaches shared high fusion rates (94%) and relatively low complication rates (11.7%). However, surgical strategies incorporating an anterior approach were notable for vascular complications (4-7%), as well as perioperative mortality (9%) not seen in the posterior-only surgery group. CONCLUSION: Where there is clinical and circumstantial equipoise regarding the choice of surgical approaches for a L5 corpectomy, this review indicates a reported mean blood loss of 2265 ml (400-4700 ml), high fusion rates (94%) and relatively low complication rates (11.7%). It is difficult to make direct comparisons between approaches due to small case series, the variability in primary pathology, clinical intent and surgeon experience.

Age - Does it really count? A study of the Perioperative Morbidity and Long-Term Outcome in Patients Above 70 Years of Age Undergoing Spine surgery for Lumbar Degenerative Disorders.

Objective To assess the long-term outcome and perioperative morbidity in spine surgeries for lumbar degenerative disorders and, thereby, to evaluate the safety of surgery in the aging population. Methods Retrospective study of patients aged > 70 years, operated for degenerative lumbar disorders between 2011 and 2015. We evaluated patient demographic, clinical and surgical data; comorbidities, perioperative complications, pre & postoperative pain scores and Oswestry disability index (ODI) scores, patient satisfaction and overall mortality. Results A total of 103 patients (Males: Females55:48) with mean age 74.6 years (70-85yrs) were studied. 60 patients (58.2%) had decompression alone, while 43 (41.8%) had decompression & fusion. Mean hospital stay was 5.7days. Mean follow-up was 47.6months (24-73mnths). Patients reported significant improvement in backpain (Numerical pain score 7.7 vs 1.6; p < 0.001), leg pain (Numerical pain score 7.4 vs 1.7; p < 0.001), disability (ODI 82.3 vs 19.1; p < 0.001) and walking distance ( p < 0.001). 76% patients were satisfied with the results at the time of final follow-up. 26 patients (25.24%) had perioperative complications which were all minor, without mortality. Most common intraoperative & postoperative complications were dural tear (6.79%) & urinary tract infection (6.79%) respectively. Conclusions With meticulous perioperative care lumbar spine surgery is safe and effective in elderly population. Patients had longer mean hospital stay in view of the gradual and comprehensive rehabilitation program. Presence of comorbidities or minor perioperative complications did not increase the overall morbidity or affect the clinical outcomes of surgery in our study.

Resumo Objetivos Avaliar o resultado no longo prazo e a morbidade perioperatória em cirurgias da coluna vertebral, devido a doenças lombares degenerativas e, assim, avaliar a segurança da cirurgia na população idosa. Métodos Estudo retrospectivo de pacientes com idade superior a 70 anos, submetidos à cirurgia em virtude de distúrbios lombares degenerativos, entre 2011 e 2015. Foram avaliados os dados demográficos, clínicos e cirúrgicos dos pacientes; comorbidades; complicações perioperatórias; escores de dor no pré e no pós-operatório; índice de incapacidade de Oswestry (ODI, na sigla em inglês); satisfação do paciente e a mortalidade geral. Resultados Foram estudados 103 pacientes (homens:mulheres, 55:48) com idade média de 74,6 anos (70 a 85 anos). 60 pacientes (58,2%) apresentaram somente descompressão, enquanto 43 (41,8%) apresentaram descompressão e fusão. O tempo médio de internação foi de 5,7 dias. O tempo médio de acompanhamento foi de 47,6 meses (24-73 meses). Os pacientes relataram melhora significativa da dor nas costas (pontuação numérica da dor 7,7 versus 1,6; p < 0,001), dor nas pernas (pontuação numérica da dor 7,4 versus 1,7; p < 0,001), incapacidade (ODI 82,3 versus 19,1; p < 0,001) e distância percorrida a pé (p < 0,001). Um total de 76% dos pacientes estavam satisfeitos com os resultados no momento do acompanhamento final. 26 pacientes (25,24%) apresentaram complicações perioperatórias, todas sem relevância e sem mortalidade. As complicações intra e pós-operatórias mais comuns foram ruptura dural (6,79%) e infecção do trato urinário (6,79%), respectivamente. Conclusões Com meticulosos cuidados perioperatórios, a cirurgia da coluna lombar é segura e eficaz na população idosa. Os pacientes tiveram um maior tempo médio de internação hospitalar, em virtude do programa de reabilitação gradual e abrangente. A presença de comorbidades ou complicações perioperatórias sem relevância, não aumentou a morbidade geral, nem afetou os resultados clínicos da cirurgia em nosso estudo.

Superior Mesenteric Artery Syndrome Complicating Spinal Deformity Correction Surgery: A Case Report and Review of the Literature.

CASE: A 13-year-old female presenting with untreated congenital scoliosis underwent single-stage anterior plus posterior deformity correction surgery. On the sixth postoperative day, she started vomiting and complained of abdominal pain. Imaging studies suggested superior mesenteric artery syndrome (SMAS). Conservative treatment for 3 weeks yielded no improvement in symptoms. She subsequently underwent laparoscopic duodenojejunostomy, which resolved her symptoms. CONCLUSIONS: SMAS, although rare, is a morbid complication of deformity correction surgery. Medical management is the treatment of choice, with surgery reserved for nonresponders. Prompt diagnosis and appropriate intervention can provide effective treatment, thus preventing catastrophic consequences.

A Radiological Study of the Association of Facet Joint Tropism and Facet Angulation With Degenerative Spondylolisthesis.

OBJECTIVE: To study the association of facet joint angulation and joint tropism with degenerative spondylolisthesis (DS) through a comparison with a matched control group. METHODS: This radiographic study was carried out in 2 groups of 45 patients each. Group A contained patients with single-level DS, while group B (control) contained non-DS patients with similar age and degeneration who underwent surgery for disc prolapse or lumbar stenosis. DS was diagnosed based on translation of ≥ 3 mm on standing lateral radiography. Axial magnetic resonance imaging from L3 to S1 was utilized to assess the angulation of facet joints in relation to the coronal plane; a difference of ≥ 8° was considered to indicate tropism. RESULTS: Among 45 patients with DS, 15 were males and 30 females. Their mean age was 62.2 years. Facet tropism was identified in 20 of 45 patients at the level of DS, 12 patients at a level proximal to DS, and 15 patients at a level distal to DS. Facet tropism was found in 7 of the 45 patients in group B. At L3-4, facet tropism was observed in 13 patients (28.88%) in group A and 2 (4.44%) in group B. At L4-5, tropism was observed in 19 patients (42.22%) in group A and 5 (11.11%) in group B. At L5-S1, tropism was seen in 17 patients (37.77%) in group A and 2 (4.44%) in group B. Group A showed a significantly higher prevalence of multilevel facet tropism and tropism at levels adjacent to the DS level. A higher average angulation of facet joints was observed in the DS group, but the difference was not statistically significant at all levels. CONCLUSION: The present study documented a statistically significant relationship between facet tropism and DS. A higher prevalence of facet tropism was also found in DS patients at non-DS levels, which is a novel observation. This finding supports the argument that facet tropism is a pre-existing morphological variation contributing to the development of DS, not a result of secondary remodelling.

Limbus Vertebral Fracture Presenting as Cauda Equina Syndrome Masquerading An Acute Disc Prolapse - A Rare Case Report and Review of Literature.

INTRODUCTION: Limbus vertebral fracture is an uncommon injury described in adolescents. It refers to the separation of a bony fragment from the unfused ring apophysis of lumbar vertebral end plate. It usually presents with back pain with/without radiculopathy masquerading an acute disc prolapse. However, the presentation as acute cauda equina syndrome has seldom been reported. CASE REPORT: A 15-year-old male presented to the casualty with a history of acute-onset low back pain and bilateral lower limb radicular pain with weakness, after lifting of a heavy Indian musical instrument (Dholak). This was associated with urinary retention and numbness in perineal region. Examination revealed L5 and S1 weakness with absent ankle jerks bilaterally. Bulbocavernosus reflex was absent. Emergency magnetic resonance imaging imaging was done, which revealed a limbus fracture of cephalad part of L4 vertebral body with displaced fragment into the spinal canal causing compression of the cauda equina. Emergency surgery was done in the form of L3-L4 midline interlaminar microscopic decompression. The patient had complete neurological recovery including the bladder control within 1 month of surgery. The patient had no functional deficits during follow-up at 3 and6 months. Dynamic radiographs taken at the end of 6 months did not show any sign of instability. CONCLUSION: When an adolescent patient with no previous history of backpain presents with acute cauda equina syndrome, a possibility of limbus fracture should also be considered. Early diagnosis and surgical decompression in such cases can bring about complete neurological recovery and excellent clinical outcome.
