Randomized Controlled Trial
The application of a computer-assisted thermoplastic membrane navigation system in screw fixation of the sacroiliac joint--a clinical study.
We inserted iliosacral screws with the aid of a computer-assisted thermoplastic membrane navigation (CATMN) system which is widely used for the accurate and repeatable location tumour in radiation therapy. We hypothesised that application of the CATMN system on IS screws' insertion will provide a superior result to conventional fluoroscopic imaging with less operative time, more accuracy and lower complication rates. ⋯ Application of CATMN system has high accuracy in treating sacroiliac joint dislocations and provides a new alternative method for guidance of the IS screw placement.
