An independent test laboratory (Applus+ LGAI Technological Center; www.applus.com) performed mechanical tests on human cadaveric skulls in order to evaluate Cranial LOOP’s load-bearing properties, following the experimental set-up described in a previously published article (Lerch KD. Neurosurgery. 1999 Apr;44(4):902-5). Cranial LOOP’s results were obtained on an Instron stress-loading apparatus, at a defined displacement of 5mm/min.

The following graph shows the load-bearing behavior of five different cranial fixation systems. Results represent the load that is required to sink the bone flap 0.5, 1 or 2 mm, which is the maximum impression depth that should be tolerated in vivo. Cranial LOOP’s result corresponds to the lowest reading among the eight tests performed by the independent laboratory.

The results of this study show that Cranial LOOP’s load-bearing properties are equivalent to those of other cranial fixation devices.
