Bone graft expanders: filling the void.
نویسنده
چکیده
Approximately 500,000 bone graft procedures are performed each year in the United States. The surge in the demand for graft material is largely the result of an increase in the number of spinal fusion procedures being performed. In 2001, only 22,000 bone donors existed worldwide, suggesting a shortage of available allograft in the future. This has led to the growing demand for bone graft substitutes.1

Soft tissue expansion with self-filling osmotic tissue expanders before vertical ridge augmentation: a proof of principle study.
INTRODUCTION Post-surgical graft exposition and loss of grafted bone are a common complication of vertical bone augmentation. Soft tissue expansion (STE) by implantation of osmotic self-filling tissue expanders before reconstructive surgery is an effective method for generation of soft tissue. The aim of this study was to investigate the feasibility of STE before bone augmentation with regard t...
متن کاملNon-union in 3 of 15 osteotomies of the distal radius without bone graft
BACKGROUND AND PURPOSE Open-wedge osteotomies of the distal radius create a void that is usually filled with either iliac crest bone graft or bone substitute. Previous studies have suggested that this is unnecessary. We investigated the safety of omitting the filling procedure. PATIENTS AND METHODS We included 15 patients with a dorsal malunion of a distal radius fracture. A palmar approach a...

متن کاملPreliminary documentation of the comparable efficacy of vitoss versus NanOss bioactive as bone graft expanders for posterior cervical fusion
BACKGROUND Laminectomies with posterior cervical instrumented fusions often utilize bone graft expanders to supplement cervical lamina/iliac crest autograft/bone marrow aspirate (BMA). Here we compared posterior fusion rates utilizing two graft expanders; Vitoss (Orthovita, Malvern, PA, USA) vs. NanOss Bioactive (Regeneration Technologies Corporation [RTI: Alachua, FL, USA]). METHODS Two succ...
متن کاملThe effect of void creation prior to vertebroplasty on intravertebral pressure and cement distribution in cadaveric spines with simulated metastases
BACKGROUND For osteoporosis or spinal metastases, percutaneous vertebroplasty is effective in pain relief and improvement of mobility. However, the complication rate (cement extravasation and fat embolisms) is relatively higher in the treatment of spinal metastases. The presence of tumor tissue plays a significant role in intravertebral pressure and cement distribution and thereby affects the o...
