Osteoporosis and metastasis may weaken the vertebrae to such a point that they fracture by effect of the compression generated by normal everyday activities, causing pain and difficulty of movement in the patients.
Compared to vertebroplasty, which is aimed solely at symptomatic treatment of pain, kyphoplasty also encourages restoring the height of the vertebral body. This is a minimally invasive percutaneous procedure whereby a balloon catheter is inserted into the vertebra to be treated through a channel created with a small-gauge cannula. The balloon is then filled with liquid containing the contrast medium in order to create a cavity and restore the height of the collapsed vertebral body, bringing it back to its natural position. After removing the balloon, the same cannula is used to inject a specific cement into the cavity, in order to stabilize and consolidate the shape of the vertebra.
The Winch™ series includes the instruments necessary for execution of the kyphoplasty procedure with both the conventional and the direct access method, also in the small-gauge versions. It is recommended to use them in combination with G21’s bone cements for vertebral consolidation.
