Disc Height Narrowing Could Not Stabilize the Mobility at the Level of Cervical Spondylolisthesis: A Retrospective Study of 83 Patients with Cervical Single-Level Spondylolisthesis

Methods@#The images of 83 patients with cervical single-level spondylolisthesis were studied. We looked at 52 slipped levels for anterior slippage and 31 for posterior slippage. The imaging parameters included slippage in the neutral, flexed, and extended positions, axial facet joint orientation, sagittal facet slope, global cervical alignment, C2–C7 angle, C2–C7 sagittal vertical axis, range of motion (ROM), and slipped disc angle ROM. @*Results@#With the narrowing of the intervertebral disc height, slippage in the flexed position of both anterior and posterior spondylolisthesis increased. However, in both anterior and posterior spondylolisthesis, disc height narrowing did not show stability. The narrowing of the intervertebral disc height was found to be a risk factor for a translation of slippage of 1.8 mm or more in flexionextension motion in anterior spondylolisthesis in multivariate regression analysis. @*Conclusions@#Narrowing the intervertebral disc height did not stabilize the translation of slippage in flexion-extension motion in cervical spondylolisthesis. Instead, narrowing of the disc height was associated with a translation of slippage of 1.8 mm or more in flexion-extension motion in cases of anterior slippage. Therefore, we discovered that degenerative cascade stabilization for cervical spondylolisthesis was difficult to achieve.

<b>Review of 33 Patients in Whom Sokeikakketsuto was Used to Treat Recurrent Cramps of the C</b><b>alf</b> / 日本東洋医学雑誌

<p>Sokeikakketsuto was administered to 33 patients with recurrent cramps of the calf appearing once a week or more and persisting for 2 weeks or more. Treatment response was evaluated 1 month after the start of drug therapy. Patients whose cramps disappeared immediately after starting were regarded as showing a complete response, those with disappearance after 1 month as showing a partial response, those with a reduction to <50% after 1 month as showing a slight response, and those in whom 50% or more of cramps persisted after 1 month as showing no response. A complete response was achieved in 12 patients, a partial response in 11, a slight response in 9, and no response in 1. In 23 (69.6%) of the 33 patients, cramps disappeared within 1 month after the start of drug therapy. In 32 (96.9%), there was a reduction to <50%. In 29 (87.8%) of the 33 patients, cramps disappeared within 3 months, suggesting the efficacy of this drug. Two-package administration in the evening/at bedtime was more effective than 1-package administration for controlling cramps of the calf at night until early in the morning. The intensive pre-attack administration of 2 packages before sleep was the most effective. Sokeikakketsuto may be useful for treating recurrent cramps of the calf.</p>
