Comparative Study
The effect of standard and low-modulus cement augmentation on the stiffness, strength, and endplate pressure distribution in vertebroplasty.
Vertebroplasty restores stiffness and strength of fractured vertebral bodies, but alters their stress transfer. This unwanted effect may be reduced by using more compliant cements. However, systematic experimental comparison of structural properties between standard and low-modulus augmentation needs to be done. This study investigated how standard and low-modulus cement augmentation affects apparent stiffness, strength, and endplate pressure distribution of vertebral body sections. ⋯ Augmentation connecting both endplates significantly strengthened and stiffened vertebral body sections also with low-modulus cement. A trend of reduced pressure concentrations above/below the cement was observed with low-modulus cement.

Multicenter Study
Effectiveness of a bone substitute (CERAMENT™) as an alternative to PMMA in percutaneous vertebroplasty: 1-year follow-up on clinical outcome.
The aim of the study was to evaluate the efficacy of an injectable and partly absorbable calcium bone cement (CERAMENT™, Bone Support, Sweden) in the treatment of osteoporotic or traumatic vertebral fractures by percutaneous vertebroplasty. ⋯ Data show that CERAMENT can be a substitute of PMMA in the treatment of osteoporotic and traumatic vertebral fractures, especially in young patients.

Randomized Controlled Trial
Treatment of MM-associated spinal fracture with percutaneous vertebroplasty (PVP) and chemotherapy.
To investigate the effect of treatment of multiple myeloma (MM)-associated spinal fracture with percutaneous vertebroplasty (PVP) and chemotherapy. ⋯ Percutaneous vertebroplasty is a minimally invasive surgery for MM-associated pathologic fracture. PVP had the characteristics of minimal trauma, easy operation and less complication. PVP can achieve long-term analgesic effect, and enhance the spinal stability.

Review Case Reports
Less invasive approaches for the treatment of cervical schwannomas: our experience.
The purpose of our paper is to illustrate our experience with minimally invasive approaches for the treatment of cervical schwannomas. Moreover, a brief review of the literature was conducted. ⋯ Minimal access procedures are increasingly gaining popularity but their use is poorly described in the treatment of cervical tumors. Less invasive approaches may effectively be used instead of traditional laminectomy in the treatment of cervical tumors, especially schwannomas, providing less iatrogenic traumatism and preventing postsurgical spinal instability. Modern neuroimaging allows adequate preoperative planning and microsurgical techniques provide adequate execution of the surgical act. The procedure has to be tailored case by case considering the specific lesional features and the individual anatomical situation.
