Indications and Contraindications

Indications

USS II Polyaxial is indicated for use in the thoracic and lumbar
spine, as well as for ilio-sacral fixations (T1–S2). It is  indicated
for the posterior treatment of:

– Degenerative diseases 
– Deformities in combination with USS II or USS Low Profile

pedicle screws

– Fractures and tumours with sufficient anterior support

when using USS II Polyaxial as a stand-alone device for
 posterior fixation

Contraindications

– In fractures with severe anterior vertebral body disruption,

an additional anterior support or column reconstruction is
 required.

Precautions

For patients with osteoporosis, the use of cancellous bone
screws is recommended.
