Single-stage posterior corpectomy for the management of spinal tumors has been well described. Anterior column reconstruction has been accomplished using polymethylmethacrylate (PMMA) or expandable cages (EC). The aim of this retrospective study was to compare PMMA versus ECs in anterior vertebral column reconstruction after posterior corpectomy for tumors(More)
BACKGROUND Small case series suggest that preoperative transcatheter arterial embolization minimizes bleeding and facilitates surgery for hypervascular metastatic bone tumors. However, control groups would make our confidence in clinical recommendations stronger, but small patient numbers make prospective trials difficult to conduct on this topic. (More)
PURPOSE OF REVIEW In metastatic spine disease, technologic advancements, neurologic recovery, pain relief, cost-effectiveness, and health-related quality of life have all strengthened surgery's and radiation's role in its management.We evaluated different surgical approaches to the spine and the multimodality treatment in the management of these cases.

Extreme lateral interbody fusion (XLIF) is a relatively new procedure for the treatment of degenerative disc disease avoiding the morbidity of anterior approaches. Ipsilateral L2-5 nerve root irritation and injury are well-described complications. We describe two patients with contralateral extremity symptoms, not reported so far. In the first patient the(More)
PURPOSE OF REVIEW To review the current status of vertebral augmentation procedures (VAPs) in the management of symptomatic vertebral compression fractures (VCFs) in cancer patients. RECENT FINDINGS The natural history of VCFs in the cancer setting is presumably different from the one seen with osteoporotic fractures. Factors contributing to the poor(More)
STUDY DESIGN Surgical technique article with retrospective case series. SUMMARY OF BACKGROUND DATA Sacral insufficiency fractures are commonly encountered in oncologic patients and constitute a cause for persistent lower back and pelvic pain. OBJECTIVE The aim of this study is to describe the modified technique of navigated percutaneous sacroiliac (SI)(More)
P53 is the best known tumor suppressor gene. If p53 is mutated, the ability of the cell to sense and repair DNA defects is lost. Failure of this mechanism increases the risk of malignant transformation and tumorigenesis. P53 overexpression is implicated in many carcinomas. P53 alterations appear to be frequent in bone and soft tissue sarcoma and have a(More)
Tumor related fractures of the spine frequently dictate surgical management. The most critical factors influencing the need and type of surgery are degree of epidural cord compression, radiosensitivity of the tumor, presence of spinal instability and patient medical status/ estimated survivorship. There is a wide spectrum of therapeutic options: major en(More)
PURPOSE To determine if differences in safety or efficacy exist between balloon kyphoplasty (BKP), vertebroplasty (VP) and non-surgical management (NSM) for the treatment of osteoporotic vertebral compression fractures (VCFs). METHODS As of February 1, 2011, a PubMed search (key words: kyphoplasty, vertebroplasty) resulted in 1,587 articles out of which(More)
Kyphoplasty (KP) and vertebroplasty (VP) have been successfully employed for many years for the treatment of osteoporotic vertebral fractures. The purpose of this review is to resolve the controversial issues raised by the two randomized trials that claimed no difference between VP and SHAM procedure. In particular we compare nonsurgical management (NSM)(More)
