BACKGROUND CONTEXT Most previous studies have investigated ligament mechanical properties at slow elongation rates of less than 25 mm/s. PURPOSE To determine the tensile mechanical properties, at a fast elongation rate, of intact human cervical anterior and posterior longitudinal, capsular, and interspinous and supraspinous ligaments, middle-third disc, and ligamentum flavum. STUDY DESIGN/S...

Purpose Little is known about the natural history of spinal deformities in Coffin-Lowry syndrome (CLS). Our goal was to evaluate the spinal deformity progression and clinical impact. Methods In this institutional review board-approved study, we performed a multinational retrospective review of six male CLS patients, aged 13 to 22 years at final follow-up, for a mean of 7.25 years (3 to 13). ...

PURPOSE To evaluate the clinical feature, operative method and prognosis of thoracic ossification of ligamentum flavum caused by skeletal fluorosis. METHODS All the patients with thoracic OLF, who underwent surgical management in the authors' hospital from 1993-2003, were retrospectively studied. The diagnosis of skeletal fluorosis was made by the epidemic history, clinical symptoms, radiogra...

Figure 1: MRI showing cervical disc prolapse (C5–6) and hypertrophied ligamentum ß avum middle and ring fingers, which had been mistakenly attributed to scabies by another dermatologist and given topical parasiticidal medication in vain. The localized pruritus used to come in bouts (not seasonal) and had significantly disturbed the patient over many months. The patient’s past medical history wa...

STUDY DESIGN Cross-sectional study. PURPOSE To investigate the relationship between ligamentum flavum (LF) thickening and lumbar segmental instability and disc degeneration and facet joint osteoarthritis. OVERVIEW OF LITERATURE Posterior spinal structures, including LF thickness, play a major role in lumbar spinal canal stenosis pathogenesis. The cause of LF thickening is multifactorial and...
