a joint distraction device for use in an arthroscopic surgery is provided . the device has a joint distraction mechanism , situated in between two bone fixation surfaces , and is capable of changing the relative distance between these two surfaces . the force generated by the mechanism should be sufficient to insert bone spikes affixed to the surfaces into bone , as well as distract the joint to create a sufficient enough gap to allow the intended procedure . with the surfaces and spikes engaged to bone at opposite sites of a joint , an increase in distraction force results in an increase in the relative distance results , hence increasing the space within the joint . embodiments of this invention , compared to fracture table approaches , effectively eliminate the risk of pudendal nerve injury , allow for longer surgical times , and allow for much more controllable joint distraction .
