The enhanced fixation and improved stability at the pin-bone interface seen with Orthofix OsteoTite Bone Screws with hydroxyapatite coating significantly reduces the incidence of pin loosening and therefore reduces the risk of infection.Orthofix OsteoTite Bone Screws with hydroxyapatite coating may eliminate the need to replace the external fixation system with an alternative treatment for long term therapy.
The hydroxyapatite coating is complemented by the well-established conical design of the Orthofix screws. Each thread cuts a new, slightly larger path in the bone on insertion, providing excellent bone purchase.
Indicated to secure fixation in cortical, cancellous and osteoporotic bone.
- Using a hydroxyapatite surface screw, the bone grows into and onto the hydroxyapatite so that the border between the two materials becomes indistinct
- This biological bond is a strong anchor which will insure long-term stability of the bone-screw construct, allowing it to withstand repetitive loading cycles without loosening of the screw
- No significant difference in insertion torque between hydroxyapatite-coated and uncoated screws
- The extraction torque is significantly greater with hydroxyapatite-coated screws than with uncoated screws
- It is possible to remove the hydroxyapatite-coated screws without the need for hospitalization, sedation or anathesia
- A clinical study demonstrated a significantly lower incidence of pin track infection with hydroxyapatite-coated screws than with uncoated screws
- A significant correlation between pin track infection and implantation in a metaphyseal site was found with uncoated screws, but not with hydroxyapatite-coated screws
