Spine
-
A prospective study. ⋯ DSA may be a reliable indicator for predicting the spinal residual growth potential in IS patients, but it should be correlated with menarchal status and chronologic ages.
-
Prospective clinical study. A quantification of volume and hydration variation of the intervertebral discs, using magnetic resonance imaging (MRI), in the lumbar spine before and after surgery performed in adolescent idiopathic scoliosis (AIS). ⋯ This work was the first report dealing with consequences of scoliosis surgery on subjacent disc in term of volume and hydration properties.
-
Prospective longitudinal study. OBJECTIVE.: To investigate, using magnetic resonance imaging (MRI), the influence of bed rest on the lumbopelvic musculature. ⋯ Bed rest resulted in selective atrophy of the multifidus muscle. An increased CSA of the trunk flexor musculature (increases in psoas, anterolateral abdominal, and rectus abdominis muscles) may reflect muscle shortening or possible overactivity during bed rest. Some of the changes resemble those seen in low back pain and may in part explain the negative effects of bed rest seen in low back pain sufferers.
-
A descriptive study of the sacral anatomic orientation (SAO) and its association with pelvic incidence (PI). ⋯ The newly suggested parameter (SAO) may be an important tool in defining the sagittal shape of the spine and understanding its association with spinal diseases.
-
A retrospective study of consecutive ankylosing spondylitis (AS) patients with spinal pseudarthrosis. ⋯ SPO at the level of pseudarthrosis was a safe and effective technique to correct sagittal imbalance without vascular complication. Surgical repair of pseudarthrosis with AIF provided successful fusion and good clinical results. For patients with lumbar hypolordosis, additional PSO was effective in restoration of sagittal balance.
