STUDY DESIGN Matched cohort. OBJECTIVE To compare the unit rod instrumentation (UR) technique with all-pedicle screw (PS) constructs in the surgical care of scoliosis in Gross Motor Function Classification System IV/V non-ambulatory spastic quadriplegic cerebral palsy patients. SUMMARY OF BACKGROUND DATA Over the past 20 years, there has been a transition from the UR technique to the use of...

PURPOSE To implement a time-of-flight MR angiographic technique using the oblique acquisition of thin gradient-echo sections to evaluate the intracranial venous system, and to assess the feasibility of application of this technique in a routine clinical setting. METHODS The MR angiographic technique consisted of a two-dimensional gradient-echo technique with sequential overlapped sections obt...

We have analysed retrospectively the relationship between the axial parameters of alignment of the lower limb and the recurrence of varus deformity after high tibial osteotomy. We studied 29 patients (37 knees) with a mean age at surgery of 66 years. The mean follow-up was for 7.4 years (5 to 10.5). Recurrence of varus deformity was defined as an increase in the femorotibial angle of 3 degrees ...

Abstract We propose a new definition of oblique plate convergence. Our model considers arc-trench curvature on spherical Earth, and defines obliquity as the angle between direction convergence azimuth from central point along arc to center arcuate trench. also show how this may be extended multiple-arc trenches. apply Western Sunda Arc, which has been traditionally considered prime example conv...

[Purpose] Little is known about the effects of biomechanical foot orthoses in scoliosis, as determined by raster stereography. The objective of this study was to investigate the effect of individually manufactured biomechanical foot orthoses on scoliosis angle, trunk imbalance, and pelvic obliquity by comparing them with general insoles by using DIERS formetric 4 dimensional in patients with sc...

BACKGROUND Coronal imbalance of the pelvis is recognized to lead to the development of degenerative lumbar scoliosis. We hypothesized that an abrupt change of pelvic obliquity may show a reproducible trend of coronal compensation in the lumbosacral spine. The aim of the study was to classify the change of coronal alignment of spine after THA. METHODS This is a retrospective study based on the...
