Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Halo pin re-tensioning
Treatment: Surgery - Placebo Re-tensioning

Placebo comparator: Control - No fortnightly re-tensioning. Placebo treatment utilises the re-tensioning procedure, pt experiences clicking sensation, however, the pin is not tightened.

Experimental: Treatment (Re-tensioning) Group - Pins are re-tensioned fortnightly back to initial fitting tension of 8lb/inch.


Treatment: Surgery: Halo pin re-tensioning
Re-tensiong every 2 weeks with torque driver. Pins are re-tensioned to 8lb/inch

Treatment: Surgery: Placebo Re-tensioning
Pts undergo re-tensioning procedure with torque driver set at zero to elicit the same clicking sensation with no tightening of the pin.
