Lateral compression type 1 (LC-1) pelvic fractures represent a heterogeneous collection of injuries. There exists little agreement amongst traumatologists with respect to treatment in the middle of the stability spectrum. This has lead some authors to suggest a role for manipulation under anesthesia to determine which injuries are best treated with fixation and those best treated without. There exist no objective criteria with respect to displacement or force to guide operative decision to surgically stabilize the pelvis or not. We hypothesize that there is exists a force displacement relationship that surgeons use to determine stability. Using a force sensor and a background reference grid we seek to objectively characterize this force/displacement relationship.
