Acetabular fractures in skeletally immature rugby players

Since the introduction of professionalism to the sport of rugby union, an increasing rate of injury has been noted in the playing population. In addition, overall participation numbers have increased globally, with more amateurs and young people involved in the sport. Acetabular fractures are generally seen after violent trauma and can be associated with poor long-term outcomes. We have previously described two acetabular fractures in young patients (16 and 24 years of age) sustained during rugby matches. We present a case series of four closed, isolated acetabular fractures in three skeletally immature male patients (13–16 years of age), two of which required open reduction and internal fixation. Three of these fractures occurred in conjunction with hip dislocations. All injuries were sustained while engaged in playing rugby union, two during seasonal match play and one during a training drill.
