High fat-sucrose (HFS) diets can reportedly produce glucose intolerance and hyperinsulinemia that may indirectly have deleterious effects on bone. The effects of a high-fat diet on calcium absorption, bone calcium content, and bone mechanical properties, however, remain controversial. Thus, we examined the morphological and biomechanical adaptations in limb(More)
STUDY DESIGN An in vitro biomechanical study of the stabilizing effects of the body augmenter and posterior instrumentation on experimental thoracolumbar fractures with vertebral defects. OBJECTIVE To evaluate the effects of the body augmenter and instrumentation on the stability of the spine-device construct. SUMMARY OF BACKGROUND DATA Posterior(More)
STUDY DESIGN An in vitro biomechanical study of the stabilizing effects of a different combination of cages and transpedicular instrumentation on experimental degenerative disc disease. OBJECTIVES To evaluate the biomechanical efficacy of the interbody fusion cage and unilateral posterior instrumentation on the stability of the spine-device construct. (More)
The efficiency of short-segment fixation with transpedicle body augmenter (a titanium spacer with bone-ingrowth porous surface, TpBA) to treat Kümmell’s disease with cord compression (stage III) was retrospectively evaluated. No laminectomy or instrumentation reduction was done. Inclusion criteria included Frankel CDE, single-level within T10–L2. FU rate(More)
Osteoporotic compression fractures (VCFs) can result in progressive kyphosis and chronic pain. Polymethylmethacrylate has been used for augmentation of VCFs; however, there are cement complications, and long-term fracture healing is unknown. The transpedicle body augmenter (TpBA), a porous titanium spacer, has been reported as an internal support to(More)
STUDY DESIGN Transpedicle body augmenter vertebroplasty of painful vertebral tumor was retrospectively evaluated. OBJECTIVE Transpedicle body augmenter vertebroplasty was designed to treat spinal tumor with intractable pain refractory to conservative management, deformity, biomechanical impairment, and neural deficits. SUMMARY OF BACKGROUND DATA(More)
STUDY DESIGN Retrospective. OBJECTIVE To evaluate the clinical and radiographical results. SUMMARY OF BACKGROUND DATA The evolution of posterior approach for burst fractures was from long-segment to short-segment and then to monosegmental fixation. Decompression of the spinal cord is performed by anterior or posterior approaches. The technique attempts(More)
BACKGROUND Short-segment fixation alone to treat thoracolumbar burst fractures is common but it has a 20-50% incidence of implant failure and rekyphosis. A transpedicle body augmenter (TpBA) to reinforce the vertebral body via posterior approach has been reported to prevent implant failure and increase the clinical success rate in treating burst fracture.(More)
Dear Sirs: I appreciate your interest and comments regarding the article by Li et al. [1]. I received numerous comments about this paper. I and the other authors of that article believe more discussion and critical review will aid progress. In response to your concerns, first, delaying mobilization is against our principles. Our postoperative protocol is(More)
BACKGROUND Multiple osteoporotic vertebral compression fractures (VCFs) have been treated with polymethylmethacrylate augmentation; however, there are cement complications and long-term fracture healing that are unknown. Transpedicle body augmenter (a porous titanium spacer) has been reported as an internal support to reconstruct the vertebral body(More)
