A variety of surgical methods and strategies have been demonstrated for Andersson lesion (AL) therapy. In 2011, we proposed and identified the feasibility of stabilizing the spine without curettaging the vertebral or discovertebral lesion to cure non-kyphotic AL. Additionally, due to the excellent reunion ability of ankylosing spondylitis, we further came up with minimally invasive spinal surgery (MIS) to avoid the need for both bone graft and lesion curettage in AL surgery. However, there is a paucity of research into the comparison between open spinal fusion (OSF) and early MIS in the treatment of AL. The purpose of this study was to investigate and compare the clinical outcomes and radiological evaluation of our early MIS approach and OSF for AL. A total of 39 patients diagnosed with AL who underwent surgery from January 2004 to December 2022 were retrospectively screened for eligibility. Patients with AL were divided into an MIS group and an OSF group. The primary outcomes were union of the lesion on radiograph and CT, as well as the visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores immediately after surgery, and at the follow-up (mean 29 months (standard error (SE) 9)). The secondary outcomes were total blood loss during surgery, operating time, and improvement in the radiological parameters: global and local kyphosis, sagittal vertical axis, sagittal alignment, and chin-brow vertical angle immediately after surgery and at the follow-up.Aims
Methods
The study was conducted to review the outcome in cases of anterior expandable interbody cages inserted through a posterior only approach. Cases selected were the anterior cage insertion and posterior stabilization patients managed by posterior only approach. Study includes the patients of various pathologies requiring 3 column support. Twenty patients were included in study. Pathology in 9 patients was tuberculosis, trauma in 3, tumours in 3, metastasis in 3 and deformities in 2patients. Patients with or without neurological deficit were included. Cases were carefully assessed and patients with single level involvement were included as more then single level involvement required more extensive exposure and possible nerve root sacrifice. Detailed neurological status was recorded. The surgery was performed in prone position and after posterior stabilization by pedicle screws the extracavitatory approach was used to insert the expandable cage. In cases of suspicious pathologies the samples for histopathology and staining were collected. Morbidity, mortality blood loss, surgical time, complications, outcome of surgery were compared with historical controls of front and back surgery. The insertion of cages from posterior approach was feasible in all carefully planned cases. None of the patients had problem related to implant in form of cage displacement. All the patients had satisfactory outcome. Posterior stabilization of spine with expandable cage insertion from posterior approach saves the operating time, spares the additional surgical incision and blood loss without compromising the outcome. In carefully planned surgeries it gives excellent results irrespective of etiology.
To describe the frequency of different patterns of pain response and their association with outcomes (prognosis) and MRI findings in patients experiencing sciatica. 176 consecutive consenting patients with radicular pain underwent an MRI and a clinical assessment at baseline using a standardized procedure of repeated lumbar movements and positioning guided. Based on their pain response, patients were divided into five groups: abolition centralization, reduction centralization, unstable centralization, peripheralization, and no effect on pain.Purpose

Introduction. Adolescent idiopathic scoliosis (AIS) is the most common paediatric spinal deformity, affecting about 3% of school-aged children worldwide. This disorder occurs in otherwise healthy children who bear no obvious deficiencies in the components of the spinal column itself. The cause of AIS is poorly understood, as is implied by the name.
