Study Design. A retrospective review of 34 patients with juvenile idiopathic scoliosis (JIS) treated with a nighttime bending brace. Objective. To determine the effectiveness of part-time bracing in JIS. Summary of Background Data. Although previous bracing studies have focused on adolescent idiopathic scoliosis, no authors have dealt specifically with part-time bracing for JIS. Methods. Twenty...
The utilization of orthotic devices for lumbar degenerative disease has been justified from both a prognostic and therapeutic perspective. As a prognostic tool, bracing is applied prior to surgery to determine if immobilization of the spine leads to symptomatic relief and thus justify the performance of a fusion. Since bracing does not eliminate motion, the validity of this assumption is questi...
In practice, the elastic lateral-torsional buckling of doubly symmetric I-section steel members is analyzed assuming free warping at supports. However, welded stiffeners, bolted end-plate connections or column base plates maintain elastically opposite flange out-of-plane rotations and thus induce substantial restraints. This paper proposes analytical formulations for evaluation critical bending...
THE EFFECTS OF ANTERIOR DISCECTOMY AND INTERPOSITION AL IMPLANT UPON LUMBAR MOTION SEGMENT STABILITY
The cadaver spine motion segment behavior under torsional load was evaluated with the disc intact, with partial anterior discectomy and with spacer insertion. The results of this study explain how anterior lumbar discectomy and interbody fusion (ALIF) affects the torsional stability of the motion segment. The pseudarthrosis rate of the anterior lumbar discectomy and interbody fusion (ALIF)...
