Nerve transfer from the median to musculocutaneous nerve to induce active elbow flexion in selected cases of arthrogryposis multiplex congenita.

Microsurgery 2019 Mar 19. Epub 2019 Mar 19.

Department of Pediatric Neurosurgery, Altona Children's Hospital, Hamburg, Germany.

Background: Arthrogryposis multiplex congenita (AMC) is a rare disease which affects mainly upper and lower extremities. Affected patients are not able to eat unassisted due to elbow contracture and nonexistent active elbow flexion. In traumatic brachial plexus palsies, a nerve transfer from either median or ulnar nerve to the musculocutaneous nerve has proved to induce active elbow flexion, and we report our results of such a procedure in a nontraumatic condition, that is, arthrogryposis.

Unusual anatomic variant of the axillary nerve challenging the deltopectoral approach to the shoulder: a case report.

Patient Saf Surg 2019 14;13. Epub 2019 Feb 14.

1Division of Orthopaedic Trauma & Complex Adult Reconstruction, Department of Orthopaedic Surgery, Jersey City Medical Center - RWJBarnabas Health, 377 Jersey Ave, Suite 280A, Jersey City, NJ 07302 USA.

Background: The deltopectoral approach is a well-described surgical approach to the proximal humerus and glenohumeral joint. One of the structures at risk during this approach is the axillary nerve. Typically, the axillary nerve arises off the posterior cord of the brachial plexus and courses lateral to the proximal humerus and inferior to the glenohumeral joint, exiting the axilla through the quadrangular space.

Microglia exit the CNS in spinal root avulsion.

PLoS Biol 2019 Feb 22;17(2):e3000159. Epub 2019 Feb 22.

Department of Biological Sciences, University of Notre Dame, Notre Dame, Indiana, United States of America.

Microglia are central nervous system (CNS)-resident cells. Their ability to migrate outside of the CNS, however, is not understood. Using time-lapse imaging in an obstetrical brachial plexus injury (OBPI) model, we show that microglia squeeze through the spinal boundary and emigrate to peripheral spinal roots. Read More

LINGO-1 shRNA loaded by Pluronic F-127 promotes functional recovery after ventral root avulsion.

Tissue Eng Part A 2019 Feb 22. Epub 2019 Feb 22.

Dongguan, China ;

Spinal root avulsion typically leads to massive motoneuron death and severe functional deficits of the target muscles. Multiple pathological factors such as severe neuron loss, induction of inhibitory molecules, and insufficient regeneration are responsible for the poor functional recovery. LINGO-1, a CNS-specific transmembrane protein that is selectively expressed on neurons and oligodendrocytes, serves as a potent negative mediator of axonal regeneration and myelination in CNS injuries and diseases.

Stereotactic body radiotherapy for centrally located stage I non-small cell lung cancer.

Transl Lung Cancer Res 2019 Feb;8(1):58-69

Department of Radiation Oncology, University of Toronto, Toronto, Canada.

Stereotactic body radiotherapy (SBRT) has become the standard of care for the treatment of early stage non-small cell lung cancer in high risk or medically inoperable patients. It is very well tolerated when given to peripherally located tumors and is associated with high rates of local control. Centrally located tumors represent a bigger challenge as they are closer to a number of critical structures, namely the major bronchi, esophagus, large vessels and brachial plexus, that can be damaged by the high ablative doses of SBRT needed for optimal tumor control.

Utility of MRI neurography in neurofibromatosis type I: Case example and review of MRI neurography literature.

Surg Neurol Int 2019 25;10:12. Epub 2019 Jan 25.

Department of Neurosurgery, University of Arkansas for Medical Sciences, Little Rock, AR, USA.

Background: Neurofibromatosis is an autosomal dominant disorder of the nerves, resulting in café-au-lait spots, axillary freckling, macules, and neurofibromas throughout the nervous system. Diagnosis of this condition has in the past been mainly clinical, but the usage of magnetic resonance imaging neurography (MRN) is a new diagnostic modality. Here, we report on a case of neurofibromatosis type I (NF-1) that was diagnosed using MRN after a protracted clinical course. Read More

Prone position surgery for a professional sumo wrestler with thoracic ossification of the posterior longitudinal ligament resulting in intraoperative brachial plexus injury by hypertrophic pectoral muscles.

J Clin Neurosci 2019 Feb 15. Epub 2019 Feb 15.

Department of Orthopedic Surgery, Graduate School of Medical Sciences, Kyushu University, Japan.

Surgery in the prone position is associated with a variety of complications due to the positioning, including the widely recognized peripheral nerve compression injuries and brachial plexus neuropathy. Previous studies have reported that thin body habitus is a predisposing risk factor for the compressive peripheral nerve injuries due to the prone position surgery. However, prone-position-related brachial plexus injury in patients who are overweight due to hypertrophic muscles have never been reported. Read More
