Pregnancy and Lactation Associated Osteoporosis in a 24-Year-Old Presenting with Multiple Fragility Fractures in the Dorsolumbar Spine: A Case Report and Review of Literature.

Introduction: Osteoporosis is rare in the young having an incidence of 4.1 per 100,000 person-years and can occur secondary to endocrine diseases, inflammatory disorders, malnutrition or malabsorption syndromes, and medications. Pregnancy and lactation-associated osteoporosis (PLO) should be thought of as one of the causes but is often missed as the diagnosis requires a high degree of suspicion along with X-rays and densitometry which are avoided as far as possible during the peripregnancy period.

"Critical pedicle wall" breaches analysis in complex spinal deformity using O-arm navigation.

Background: Free-hand and fluoroscopic-guided pedicle screw placement has been associated with higher rates of pedicle breaches (frequency range 15-40% especially in deformed pedicles). Neurological complications are more "critical" (i.e.

Learning curve across 2000 thoracolumbar pedicle screw placements using O-arm navigation: technical difficulties and their solutions.

Introduction: Instrumentation using the intraoperative O-arm navigation technique appears safer than its predecessor techniques. However, only a handful of surgeons often used navigation during spinal surgeries. Too many operative glitches and unreliable navigation accuracy were the important reasons cited even by experienced surgeons for not using spinal navigation.

O-arm Navigated en bloc Excision of a Solitary Subaxial Cervical Osteochondroma Presenting as Myelo-radiculopathy: A Case Report.

Introduction: Vertebral osteochondroma is a rare entity. It presents with varied complaints ranging from palpable mass to myeloradiculopathy. En bloc excision is the gold standard treatment option for symptomatic patients.

Emergently Managed Rare Case of Extraosseous Hemorrhagic Spinal Epidural Cavernous Hemangioma: A Case Report.

Introduction: Commonly spinal cavernous hemangioma (CH) is found in vertebral body at thoracic level. Purely extraosseous epidural CH contributes only 4% of all CH. In addition, these patients usually present in their 3rd-6th decade of life.

Efficacy of less Invasive modified O-arm navigated delta fixation in osteoporotic high-grade spondylolisthesis: "a LIMO delta technique".

Purpose: In 1994, the technique of transdiscal screws fixation in spondylolisthesis was introduced but did not gained popularity as it failed to address problems with spinal sagittal imbalance, retroverted pelvis, pseudoarthrosis, implant failure and neural injury. Majority of problems were due to lack of clear indications; hence, in this study, with modification of traditional technique and use of O-arm navigation for selected group of patients, we have addressed the above problems and given good to excellent functional outcomes.

Methods: We did prospective study on 15 patients with osteoporotic high-grade spondylolisthesis Meyerding grade 3 & 4 admitted in period 2020-2021.

Utility of selected sequence MRI imaging of the axial skeleton in the diagnosis of axial spondyloarthritis.

Background: Whole body MRI has been used to evaluate inflammatory lesions associated with axial spondyloarthritis (SpA). These sequences are extensive, time consuming and add to the cost of the investigation. We aimed to determine the utility of selected sequence MRI imaging of the axial skeleton including spine, pelvis and sacroiliac (SI) joints to identify features of (SpA).

Standalone cage versus anchored cage for anterior cervical discectomy and fusion: a comparative analysis of clinical and radiological outcomes.

Purpose: The use of standalone cages (SAC) and anchored cages (AC) in anterior cervical discectomy and fusion surgery (ACDF) has shown advantage of reduced operative time and lower incidence of dysphagia. However, there is limited literature available comparing the clinical and radiological outcomes of SAC and AC.

Methods: We conducted a prospective study for patients undergoing ACDF for cervical radiculopathy or myelopathy.

A Stepwise Posterolateral Approach for Computed Tomography Guided C2 (Axis) Transpedicular Biopsy: A Technical Note.

Introduction: Minimally invasive percutaneous CT-guided biopsies of the spine are well established. Although, technical difficulties with CT-guided percutaneous intervention of the C2 body present due to the smaller size of the vertebral elements and potential injury of the critical adjacent structures such as Carotid arteries laterally, vertebral artery, and cervical nerve posterolaterally, pharynx and larynx anteriorly, and spinal cord in the cervical spinal canal. Routinely transoral approach is used for the percutaneous intervention of the C2 body.

A Polyostotic Paget's Disease Involving Lumbar Spine Presenting with Cauda Equina Syndrome: An Unusual Entity.

Introduction: Paget's disease of bone (PDB) is a metabolic bone disease presenting as polyostotic or monostotic lesions of the spine. Although common in the Anglo-Saxon population, it is rare on the Indian subcontinent. Neurological complications though infrequent can be severe in pagetic spine.

Recurrent solitary bone plasmacytoma: A case report.

Background: Plasmacytoma is an hematological malignancy that originates in bone. It may involve a single skeletal location. Notably, these lesions can progress to involve multiple segments in 50% of cases, at which point they are classified as having multiple myeloma (MM).

Gene Xpert/MTB RIF assay for spinal tuberculosis- sensitivity, specificity and clinical utility.

Background: Xpert MTB/RIF assay is a rapid automated molecular test with excellent reported sensitivity, specificity for diagnosis of pulmonary and extrapulmonary Mycobacterium (MTB) infections. However, the clinical utility and accuracy in STB is not well established. A study was conducted to report on the sensitivity, specificity and clinical utility of the Xpert MTB/RIF assay in spinal tuberculosis (STB).

Clinical and radiological factors associated with postoperative shoulder imbalance and correlation with patient-reported outcomes following scoliosis surgery.

Background: Shoulder balance (SB) is an important cosmetic concern and is a determinant to assess outcomes following scoliosis surgery. Shoulder imbalance (SI) has been studied predominantly in idiopathic scoliosis with limited literature on other etiologies.

Purpose: To assess SB following scoliosis surgery and correlate SRS-30 self-image scores with radiological shoulder imbalance SI.
