It was believed, however, that this 2% difference was probably not clinically significant in most circumstances. Bed height was significantly longer than standing height by 3.68 cm, but the two measurements were equally precise. Each patient was also weighed and self-reported height, weight, sex, and age were recorded. Patients were divided into four groups based on which of two researchers performed each of the two measurements. Two measurements were performed on 108 ambulatory inpatients: (1) standing height using a standard height-weight scale, and (2) bed height using a flexible tape. This study examined the accuracy of measuring body height in bed in the supine position. Since many patients requiring specialized nutritional support are bedridden, measurement of height for purposes of nutritional assessment or prescription must often be done with the patient in bed. Gray, D S Crider, J B Kelley, C Dickinson, L C At the olisthesicĪccuracy of recumbent height measurement. Multivariate analysis was applied to the following preoperative parameters: intervertebral angle, disc height, intervertebral mobility, sagittal balance parameters, use of osteosynthesis or not. Univariate analysis searched for correlations between variation in disc height and early postoperative function and quality of fusion at last follow-up. Pre- and postoperative (early, one year, last follow-up) radiographic data were recorded: olisthesic level, disc height, intervertebral angle, intervertebral mobility (angular, anteroposterior), and global measures of sagittal balance (thoracic kyphosis, lumbar lordosis, T9 sagittal tilt, pelvic version, pelvic incidence, sacral slope). A dedicated self-administered questionnaire was used to collect data on pre- and postoperative function, the SF-36 quality of life score, and patient satisfaction.
#SAQ PANORAMIC VLF RECEIVER SERIES#
This was a retrospective analysis of a consecutive series of 66 patients with mean 52 months follow-up (range 3-63 months). In order to obtain a homogeneous group of patients, the series was limited to patients undergoing posterolateral arthrodesis for degenerative spondylolisthesis, in combination with radicular release.
The purpose of this work was to investigate the spinal segment immobilized by the posterolateral fusion: height of the anterior intervertebral space, the clinical and radiographic impact of changes in disc height, and the short- and long-term impact of disc height measured preoperatively on clinical and radiographic outcome. Few studies have been devoted to the impact of disc height on the outcome of posterolateral fusion. The stability deficit increases with increasing height of the anterior intervertebral space, which for some warrants the adjunction of an intersomatic arthrodesis in addition to the posterolateral graft. ĭrain, O Lenoir, T Dauzac, C Rillardon, L Guigui, PĮxperimentally, posterolateral fusion only provides incomplete control of flexion-extension, rotation and lateral inclination forces.
