We review the surgical anatomy of the thoraco-lumbar spine region located between the eleventh thoracic and the second lumbar vertebrae (T11-L2). Anatomical features of muscular, vascular and neural structures important to surgical approaches are described in details. We also discuss surgical nuances of the transthoracic retroperitoneal and the lateral retropleural approaches. We conclude that anatomical knowledge is important to improve the efficacy and safety of surgical procedures in the thoraco-lumbar spine region.

A successful surgery cannot be done without adequate knowledge of the surgical anatomy, especially in liver trauma, where anatomical knowledge plays a key role when it comes to making quick decisions that will allow saving the life of patients with this pathology in the emergency. Assess liver anatomical knowledge and related structures for conducting emergency surgical approaches mobilization maneuvers and vascular control. A 3-year training program for vascular control maneuvers and liver mobilization, for 11 surgical residents during their second, third and fourth year, while 3 fresh corpses and 20 formolized at 10 % corpses were used. Different maneuvers of liver mobilization and vascular control were performed from the second year onward for three consecutive years. A decrease of 57 % was observed in the time of realization of the maneuvers and recognition of structures in second year residents who conducted this test for three consecutive years, and a decrease of 38 % in second and third year residents who performed it for two consecutive years with similar results. Anatomical knowledge in stage training improves the surgical approach to trauma patients, decreasing the time of realization of the maneuvers and the risk of complications.

Biomechanical Strength

Assessment of osteoporosis-associated fracture risk during clinical routine is based on the evaluation of clinical risk factors and T-scores, as derived from measurements of areal bone mineral density (aBMD). However, these parameters are limited in their ability to identify patients at high fracture risk. Finite element models (FEMs) have shown to improve bone strength prediction beyond aBMD. This study aims to investigate whether FEM measurements at the lumbar spine can predict the biomechanical strength of functional spinal units (FSUs) with incidental osteoporotic vertebral fractures (VFs) along the thoracolumbar spine. Multi-detector computed tomography (MDCT) data of 11 patients (5 females and 6 males, median age: 67 years) who underwent MDCT twice (median interval between baseline and follow-up MDCT: 18 months) and sustained an incidental osteoporotic VF between baseline and follow-up scanning were used. Based on baseline MDCT data, two FSUs consisting of vertebral bodies and intervertebral discs (IVDs) were modeled: one standardly capturing L1-IVD–L2-IVD–L3 (FSU_L1–L3) and one modeling the incidentally fractured vertebral body at the center of the FSU (FSU_F). Furthermore, volumetric BMD (vBMD) derived from MDCT, FEM-based displacement, and FEM-based load of the single vertebrae L1 to L3 were determined. Statistically significant correlations (adjusted for a BMD ratio of fracture/L1–L3 segments) were revealed between the FSU_F and mean load of L1 to L3 (r = 0.814, p = 0.004) and the mean vBMD of L1 to L3 (r = 0.745, p = 0.013), whereas there was no statistically significant association between the FSU_F and FSU_L1–L3 or between FSU_F and the mean displacement of L1 to L3 (p > 0.05). In conclusion, FEM measurements of single vertebrae at the lumbar spine may be able to predict the biomechanical strength of incidentally fractured vertebral segments along the thoracolumbar spine, while FSUs seem to predict only segment-specific fracture risk.

Objectives: Low bone mass is a common disorder in elderly population which predisposes to fracture with minimal trauma. This study was performed to find out the association between the Body Mass Index (BMI) and Bone Mineral Density (BMD) in postmenopausal women.Materials and Methods: This cross sectional study was carried out at Institute of Nuclear Medicine and Allied Sciences Comilla and Mitford, Dhaka over a period of 12 months from January 2013 to December 2013. A total 93 postmenopausal women were enrolled for this study. All postmenopausal women underwent a BMD scan of femoral neck and lumbar vertebrae using a Dual Energy X-ray Absorptiometry (DEXA). Participants were categorized into three groups according to their age and BMI. BMD were expressed base on T-score according to WHO criteria. The relation among BMI, age and BMD were assessed.Results: The results of this study showed that the mean age of the study group was 57.13±7.49 years with range of 46 to 75 years. The most postmenopausal women were in age group 55-65years. The mean BMI of the study subjects were 24.18±5.08 kg/m2 with a range of 15.62 to 36.20 kg/m2. Among 93 subjects osteopenia was greater at lumbar spine (45.2%) with T-score mean±SD-1.83±0.33 and osteoporosis at femoral neck (51.6%) with T-score mean ±SD-3.36±-0.67. Pearson’s correlation coefficient test showed inverse relationship between age and BMD both lumbar spine (r = -0.301, p = 0.003) and femoral neck (r = -0.303, p=0.003) whereas the positive relation between BMI and BMD both at lumbar spine (r=0.338, p=0.001) and femoral neck (r =0.343, p=0.001). These showed that with advancing age, BMD decreases and the risk of osteoporosis increases and with increasing BMI, BMD increases and risk of osteoporosis decreases.Conclusion: The findings of this study portrait that aging and low BMI are risk factors associated with bone loss. So preventive measure should be taken for high risk post menopausal women.Bangladesh J. Nuclear Med. 17(2): 138-141, July 2014

Real progress is being made with the Eagle Project – the multimillion-pound scheme to convert the education facilities on the fourth floor of the College. The recent highly successful College conference Anatomy Teaching – the Cruellest Cut of All (see page 194), reconfirmed the central importance of the Eagle Project in teaching surgical anatomy and in maintaining high standards in surgical practice. The conference highlighted the stark and worrying effects of a changing undergraduate curriculum on levels of basic anatomical knowledge. This in turn impacts on postgraduate examination results and on levels of litigation in the NHS. The capacity and diversity of the Eagle Project's facilities provide the College with a unique resource to tackle these problems at every level – undergraduate, postgraduate and consultant.

Surgical treatment of patients with spinal injuries, accompanied by traumatic stenosis of the spinal canal, is an urgent and discussed problem of modern vertebrology. Surgical treatment of 111 patients with various injuries of the thoracolumbar spine was performed. In 40 patients, post-traumatic stenosis was eliminated using ligamentotaxis using transpedicular osteosynthesis. The immediate results of treatment were followed up in all patients: good results were obtained in 33 (82.5%) cases; satisfactory — in 6 (15.0%), unsatisfactory — in 1 (2.5%). Long-term results with a follow-up of more than 1 year were followed up in 27 (67.5%) patients; good results were obtained in 20 (74.0%), satisfactory in 7 (25.0%).

AbstractA known prevalence of concurrent cervical and lumbar spinal stenosis was shown to be 5–25%, but there is a lack of evidence regarding direct relationships in canal dimension and canal-body ratio between cervical and lumbar spine. Total 247 patients (mean age: 61 years, male: 135) with cervical and lumbar computed tomography scans were retrospectively reviewed. Midsagittal vertebral body and canal diameters in reconstructed images were measured at all cervical and lumbar vertebrae, and canal-body ratios were calculated. The canal diameter and ratio were also compared according to the gender and age, and correlation analysis was performed for each value. There were significant correlations between cervical (C3–C7) and lumbar (L1–L5) canal dimension (p < 0.001). C5 canal diameter was most significantly correlated with L4 canal diameter (r = 0.435, p < 0.001). Cervical canal-body ratios (C3–C7) were also correlated with those of lumbar spine (L1–L5) (p < 0.001). The canal-body ratio of C3 was most highly correlated with L3 (r = 0.477, p < 0.001). Meanwhile, mean canal-body ratios of C3 and L3 were significantly smaller in male patients than female (p = 0.038 and p < 0.001) and patient’s age was inversely correlated with C5 canal diameter (r = − 0.223, p < 0.001) and C3 canal-body ratio (r = − 0.224, p < 0.001). Spinal canal dimension and canal-body ratio have moderate degrees of correlations between cervical and lumbar spine and the elderly male patients show the tendency of small canal diameter and canal-body ratio. This relationship of cervical and lumbar spine can be an important evidence to explain to the patients.

The paper presents the data of evaluation of dysfunction in lumbosacral pain in 898 athletes, ballet and circus artists aged 15 to 45 years. The median age was 25.8 year. 537 men and 361 women. In 409 people, pain syndrome is caused by osteochondrosis of the lumbar spine. 238 patients were diagnosed with spondylolysis of the lower lumbar vertebrae, 172 with facet syndrome, spondylarthrosis and 79 with pathology of the ligaments of the lumbosacral spine. Asymmetry in strength, tone of muscles-stabilizers of the spine and their bioelectric activity, which are eliminated in the course of treatment, was noted.
