The High V+ is indicated for the fixation of pathological fractures of the vertebral body using vertebroplasty or kyphoplasty procedures.
Painful vertebral compression fractures of the vertebral body may result from osteoporosis, benign lesions (hemangioma), or malignant lesions (metastatic cancers, myeloma).
Immediately after mixing phase, viscosity of High V+® Radiopaque bone cement reaches a very high level (circa 1300 Pa.s) compared to low vertebroplasty bone cements with initial viscosity around 5-10 Pa.s or medium ones with initial viscosity around 100 Pa.s. As a consequence, risks of leakages, the most encountered problem encountered in vertebroplasty are highly reduced.
Even if viscosity is high in first stage, the injection time remains long enough to permit a safe injection: viscosity increases more slowly afterward. With High V+® Radiopaque bone cement, procedure of vertebroplasty and kyphoplasty becomes easier for the operator and safer for the patient.
High V+® has a high rate of barium sulfate opacifier associated with hydroxyapatite(36.4%) for an ideal and maximum visibility during the whole procedure.It can be used either under fluoroscopy or CT scan.
HARDENING / MECHANICAL PROPERTIES :
The maximum temperature reached during hardening of High V+® around 56°C is far below the ISO 5833 standard, then reducing the risk of thermic necrosis. Hardening time(min) at 20°C : 16 min
Mechanical properties of High V+® are also consistent with standard ISO 5833 norms.
