Simple and Economical Method to Create Thoracolumbar Burst Fracture in a Calf Spine Model.
CONCLUSIONS: We describe a technique to create thoracolumbar burst fractures in calf spine by a drop weight method using a device that is simple to operate and easy to construct. The method is consistent and produces fractures similar to those occurring naturally, and can be considered as an alternative method for creating burst fractures in biomechanical studies.

Correlation of Vitamin D and Body Mass Index with Modic Changes in Patients with Non-Specific Low Back Pain in a Sub-Tropical Asian Population.
The objective of this study was to assess body mass index (BMI) and investigate vitamin D levels in patients with low back pain (LBP) and study a possible relationship with myopathy-related symptoms and Modic changes. OVERVIEW OF LITERATURE: LBP is a multifactorial problem and the search for its patho-anatomical causes is ongoing. Modic changes seem to be a cause of back pain but the pathological mechanisms underlying this are not completely defined. Hypovitaminosis D and obesity have also been shown to cause chronic musculoskeletal pain. The relationship between vitamin D deficiency and BMI with Modic changes has not ...

Cervical Footprint Anthropometry in Indian Population: Implications on Design of Artificial Disc Replacement Devices.
CONCLUSIONS: This study indicates need for redesign of cervical disc prostheses to match Indian patients. The collected anthropometric dimensions from this study may be used to design and develop indigenous artificial total disc replacement prosthesis and even cervical cages in India. With the present study being a small pilot study, the authors recommend anthropometric CT measurements in larger number of Indian patients in order to validate footprint dimensions for designing better-matched prosthesis.

Total Excision of a Giant Ventral Midline Cervical Spinal Intradural Schwannoma via Posterior Approach.
Authors: Das JM, Peethambaran A Abstract Schwannomas are the most common intradural extramedullary tumors of the spine. They usually occupy a posterolateral or lateral position in relation to the cord. The ventral midline is a very rare location for the origin of a spinal schwannoma. A giant one in such a location causes technical difficulties in excision. Here, we present a giant cervical spinal schwannoma, located ventral to the cord, in a 38-year-old lady who presented with features of myelopathy and bladder involvement. Magnetic resonance imaging was suggestive of an intradural extramedullary lesion extending f...

Navigated Pin-Point Approach to Osteoid Osteoma Adjacent to the Facet Joint of Spine.
Authors: Mori K, Neo M, Takemoto M, Nishizawa K, Imai S Abstract Osteoid osteoma (OO) is a benign osteoblastic tumor. Its curative treatment is complete removal of the nidus, where intraoperative localization of the nidus governs clinical results. However, treatment can be difficult since the lesion is often invisible over the bony surface. Accordingly, establishment of an ideal less invasive surgical strategy for spinal OO remains yet unsettled. We illustrate the efficacy of a computed tomography (CT)-based navigation system in excising OO located adjacent to the facet joint of spine. In our 2 cases, complete and ...

CONCLUSIONS: The spinal column should always be scanned to rule out a secondary or tertiary vertebra fracture in vertebral fractures associated with high-energy trauma.

In MNSF with ≤4 intact vertebra in between, stabilization of one segment should prompt the involvement of the secondary fracture into the system. PMID: 26713121 [PubMed] (Source: Asian Spine Journal)
