The paraspinal muscle-tendon system: Its paradoxical anatomy.

PLoS One 2019 8;14(4):e0214812. Epub 2019 Apr 8.

Complexité, Innovations, Activités Motrices et Sportives, CIAMS (EA4532), Paris-Sud University, Paris-Saclay University, Orsay, France.

Anatomy of the muscle-tendon system is an important component to musculoskeletal models. In particular, the cross-sectional area of belly (mCSA) and tendon (tCSA) provides information about the maximum force that a muscle may exert. The ratio of mCSA to tCSA (rCSA) demonstrates how muscle force is related to the ability to resist/transmit the force to bone. Read More

Dynamic Cervical Cord Compression Post-laminectomy Visualized by Flexion-extension Magnetic Resonance Imaging: Case Report.

Cureus 2019 Jan 14;11(1):e3878. Epub 2019 Jan 14.

Neurosurgery, The Icahn School of Medicine at Mount Sinai, New York, USA.

Flexion-extension magnetic resonance imaging (MRI) in the cervical spine is not universally used in cervical spine surgery. However, flexion-extension MRIs can identify previously undetected spinal stenosis, improve surgical decision-making, and maybe a better tool to evaluate postoperative outcomes. One uncommon complication after laminectomy, to treat cervical spinal stenosis, is muscle weakness due to subsequent dynamic cord compression by posterior paraspinal musculature. Read More

Percutaneous Endoscopic Transforaminal Approach for Far Lateral Lumbar Discectomy: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2019 Mar 19. Epub 2019 Mar 19.

Department of Neurosurgery, Nanoori Incheon Hospital, Incheon, Republic of Korea.

The conventional surgical approach to far lateral lumbar disk herniations is a paraspinal Wiltse approach. During the Wiltse approach, it is sometimes necessary to resect some of the facet or pars interarticularis to achieve an adequate exposure. The endoscopic transforaminal route can be of benefit in far lateral disk herniations due to direct access to the epidural space through Kambin's triangle, without the need for any bony removal or nerve retraction.

Systemic manifestations of extraskeletal myxoid chondrosarcoma associated with a novel t(2;22)(q34;q12) EWS translocation in a child and a review of the literature.

Pediatr Hematol Oncol 2018 Oct - Nov;35(7-8):434-441. Epub 2019 Feb 18.

b The Children's Hospital at Montefiore , Bronx , New York , USA.

Extraskeletal myxoid chondrosarcoma (EMC), a soft-tissue sarcoma with unique clinicopathologic features and characteristic chromosomal translocations, is extremely rare in the pediatric population. We, herein, present the case of a 7-year-old boy with profound microcytic hypochromic anemia, poor weight gain and a mid-thoracic paraspinal mass that was identified as EMC. Systemic manifestations of localized, nonmetastatic EMC have never been described in the pediatric population, yet our patient's anemia and poor weight gain resolved after successful surgical resection of the tumor, suggesting that localized EMC can present with systemic manifestations.

Development of a New Coupled Cobb-Suction Instrument for Posterior Spinal Approaches: Technical Note.

World Neurosurg 2019 Feb 15. Epub 2019 Feb 15.

Federal University of the State of Rio de Janeiro (UNIRIO) - Rio de Janeiro/RJ, Brazil.

During dissection of paraspinal muscles in posterior surgical approaches, the spine surgeon usually holds a subperiosteal (Cobb) elevator in one hand and a monopolar cautery in the other hand. In such a scenario, both the surgical smoke generated by the monopolar as well as eventual bleedings constitute a significant hindrance to simultaneous bilateral dissection of the paraspinal muscles by two surgeons. In order to address the identified shortcomings in the currently available instrumentation the authors initially analyzed the most common surgical techniques employed by residents and fellows at our institution for paraspinal muscle dissection during posterior spinal approaches.
