Short-lasting surgery, single anaesthesia, reduced morbidity and hospital stay as well as costs, an early return to function, high patient satisfaction rate with encouraging results justify single-stage surgery in TSS. Age, blood loss and duration of surgery decide the complication rate and outcome of surgery. Staged surgery is recommended in patients above the age of 60 years.
Study design: This prospective study evaluates the effectiveness of transpedicular biopsy carried out under local anesthesia in obtaining diagnostic tissue from vertebral body lesions. Objective: To describe the technique of percutaneous transpedicular biopsy carried out under local anesthesia under C-arm fluoroscopy and to report the author 0 s experience. Setting: Spine hospital, Ahmedabad, Gujarat, India. Methods: Seventy-one patients who underwent transpedicular biopsy from T6 to S1 vertebral body lesions were evaluated. Biopsy specimens were obtained by passing a self-designed 5-mm diameter biopsy instrument through the pedicle into the site of the disease using C-arm fluoroscopy. Specimens were sent for histological and bacteriologic analyses. Results: Biopsy was carried out for vertebral lesions of 51 men and 20 women. Sixteen of these lesions were seen in thoracic spine, 53 in lumbar and two in sacrum. The pathologic examinations revealed infections in 25, osteoporotic wedging in 21, metastasis in eight, plasmacytoma in three, multiple myeloma in four, non-Hodgkin 0 s lymphoma in one and round cell tumor in one patient. Diagnosis was established in 63 of 71 patients (88.7%). Remaining eight patients were reported as chronic nonspecific inflammation, and were followed up for more than 6 months. Conclusion: Percutaneous transpedicular vertebral biopsy under local anesthesia is an important tool in the evaluation of vertebral body lesions, especially in older population and can be performed with minimal morbidity and high diagnostic yield as an outpatient procedure.
This study reviews the presentation, etiology, imaging characteristics and reasons for missed diagnosis of Andersson lesion (AL) and analyzes the surgical results of short segment fixation in the thoracolumbar region. This is a retrospective single center study. Fourteen patients (15 lesions) who were operated for AL were analyzed. The study was designed in two parts. The first part consisted of analysis of clinical and radiological features (MRI and radiographs) to highlight, whether definitive characteristics exist. The second part consisted of analysis of outcome of short segment fixation as measured by VAS, Frankel score, AsQoL index, and union, with assessment of complications. The follow-up was 42.33 ± 19.29 months (13 males and 1 female) with a mean age of 61.13 ± 19.74 years. There was predisposing trauma in five patients. There was a delay in presentation of the patients by 5.86 ± 2.50 months. There was misdiagnosis in all the cases, at primary orthopedic level (ten cases were put on anti-tuberculous treatment due to its MRI resemblance to infection) and all but one case at radiologist level. Radiographs and MRI had characteristic features in all cases, and MRI could detect posterior element affection in 14 lesions as against only 8 posterior lesions detected in radiographs. In all patients, there was a patient's delay and/or physician's delay to arrive at a diagnosis. Spinal fusion was seen in all the cases. Outcome measures of VAS, Frankel score, and AsQoL index showed significant improvement (P \ 0.002). No major complications occurred. There is a lack of awareness of AL leading to misdiagnosis. Definite clinico-radiological features do exist in AL and short segment fixation is effective.
Use of UBS is likely to provide a safe, rapid, and effective surgery when compared to conventional rongeurs and high-speed burr. The advantages such as lower blood loss and lower intra-operative incidental dural tears were noted with the use of UBS.
Study Design A retrospective comparative analysis of 64 patients with cauda equina syndrome (CES), who underwent either decompression alone (NF) or fusion (F) surgery. Purpose We compared the outcomes and timing effects. Overview of Literature CES can cause loss of autonomic control of vesicular function and lower limb neurological deficits. Prompt diagnosis and emergency surgery markedly improve outcome. Although decompression only is a mainstream technique, there is guarded recovery of vesicular dysfunction. Decompression ventrally in a narrow window requires manipulation of neural tissue in an already jeopardised critical canal and may accentuate irreversible damages. In F surgery, the adequate exposure leads to a lower neural manipulation. Methods Until January 2008, we treated CES with decompression (laminectomy and/or discectomy). However, from that month forward, all our single-level CES patients have received a fusion operation. In this study, characteristic categorical variables and outcomes were analysed. Results In a retrospective analysis of 64 patients, NF (n=37) and F (n=27) who received treatment, we found that both groups improved significantly on follow-up in all objective parameters. Although, the comparison of clinical and functional outcome data between the two groups was statistically insignificant, the average value of objective outcome such as vesicular function, low back pain (LBP), and complications was better for patients in F group compared with NF group. However, the patient satisfaction for the F group was also lower, in view of their residual symptoms and disabilities. Contrary to common perceptions, we found that the timing of surgery does not influence the recovery rate for either approach. Conclusions Although both the techniques appear to be equally effective, the fusion approach overall showed a definite edge over non-fusion, with respect to reduced incidence of iatrogenic dural tears, LBP, and overall outcome, even despite the lower patient satisfaction.
