Abstract:During open reduction and internal fixation of a midshaft clavicle fracture it is not uncommon that the osteosynthesis plate has to be bent perioperatively to fit the curvature of the clavicle. This takes time and is suboptimal in the sterile environment. To avoid the need for bending the plate we developed a method where the plate is preoperatively bent according the curvature of a plastic replica of the fractured clavicle, created using rapid prototyping. The aim of this study was to test this method. The hypothesis was that this will shorten plate handling time and improve surgical workflow. A non-blinded, prospective cohort study was performed. The control group received conventional operative treatment using standard precontoured clavicle locking plates. The intervention group received operative treatment by means of described method. In both groups four specific proceedings were timed. Eight subjects were included in the control group and seven in the intervention group. A plate handling time reduction of 2:04 minutes (p:0.563) was measured, however this time reduction was associated with a lengthened average surgery time of 9:22 minutes (p:0.132). A good integration of the method in the workflow of the surgical team was accomplished. It is possible to implement this rapid prototyping method in fracture treatment. No significant time reduction can be stated, however the concept of having a preoperatively contoured plate available is dearly appreciated by the surgeons. The method would be more valuable with more complex fracture types.
