Theory of Bowstring Disease: Diagnosis and Treatment Bowstring Disease.

Orthop Surg 2019 Feb;11(1):3-9

Department of Orthopedic Surgery, Spine Center, Changzheng Hospital, Second Military Medical University.

Bowstring disease (BSD) is a new classification of spine disease caused by axial stretched lesion on nerve roots and the spinal cord, which is differentiated from disc herniation and canal stenosis in that it is caused by nerve compression lesions. BSD could be caused by mismatched growth rates between the spine and nerve roots (the juvenile type), or by imbalanced degenerative rates between the spine column and nerve roots (degenerative type). Here, we propose that there are several self-adjust mechanisms to relieve axial nerve tension: (i) nerve growth; (ii) posture adjustment and low back pain; (iii) autogenous degeneration of intervertebral disc; and (iv) idiopathic and degenerative scoliosis.

[Lumbar spinal stenosis].

Ugeskr Laeger 2019 Feb;181(9)

Lumbar spinal stenosis is a clinical diagnosis of pain in the buttocks or lower extremities, with or without back pain. Symptoms increase with walking, and patients find relief when sitting or flexing the spine. Clinical care and research are complicated by the heterogeneity of the condition and high rates of anatomic stenosis on imaging studies in older people, who are completely asymptomatic. Read More

Current concepts and recent advances in understanding and managing lumbar spine stenosis.

F1000Res 2019 31;8. Epub 2019 Jan 31.

Neurosurgery, University of Texas Southwestern Medical Center at Dallas, Dallas, TX, USA.

Lumbar spinal stenosis is a degenerative process that is extremely frequent in today's aging population. It can result in impingement on the nerves of the cauda equina or on the thecal sac itself, and lead to debilitating symptoms such as severe leg pain, or restriction in the perimeter of ambulation, both resulting in dependency in daily activities. The impact of the disease is global and includes financial repercussions because of its involvement in the active work force group. Read More
