TENS for surgical stabilisation of acetabular fracture in the skeletally immature: A novel technique.

<bold>Background: </bold>Acetabular fractures in childhood are rare and the literature is scarce to describe a standard protocol in surgical management of these injuries. As the patient is still growing, it warrants a detailed assessment with a sound surgical plan if operative intervention is deemed necessary to prevent late complications. Throughout literature, most fixation rely on using pins, screws, plates or combination of the three which require large surgical exposure and risk of secondary physeal injury, hence we come up with a method of using the Titanium Elastic Nail System (TENS) to overcome this issue. We describe a novel technique in managing acetabular fractures in this group of patients using the TENS.<bold>Method: </bold>An 8 year old girl with a diagnosis of right anterior column posterior hemitransverse acetabular fracture was fixed with 3 TENS for supra-acetabular, anterior column and posterior column fragments. Surgery was performed in a minimally invasive manner. No drilling was performed during the surgery and implant insertion is done manually.<bold>Results: </bold>Advantages of this procedure include minimally invasive surgery with smaller wounds, minimal intraoperative bleeding and theoretically reduces the risk of premature fusion of the triradiate cartilage. Patient is allowed early rehabilitation with this method.<bold>Conclusion: </bold>This novel method provides an alternative to traditional usage of wires, pins, plates and screws as is described in most literature. However, it requires the surgeon to appreciate that the safe corridors for the implant are much narrower than adults. We recommend this technique for fractures that are deemed suitable for intramedullary fixation and further research in the future will be needed. [ABSTRACT FROM AUTHOR]
