A modified stoppa (technique) approach for treatment of pediatric acetabular fractures

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

BACKGROUND

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.

METHOD

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.

RESULTS

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.

CONCLUSION

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.

Modified Stoppa Approach for Acetabulum Fracture: A Review

Fracture acetabulum is a grave injury and a challenge for orthopedic surgeons. Anterior and posterior approaches have been described for fixation of acetabulum fractures. The modified Stoppa approach is considered an alternate to anterior approach, which provides access to pelvis from inside the cavity. The purpose of this article is to review the available literature on use of the modified Stoppa approach in acetabulum fractures. The available data suggest that modified Stoppa approach is useful in anterior acetabulum fractures and some posterior acetabulum fractures, especially where buttressing of medial wall is required.
