Instability of the posterior pelvic ring: introduction of innovative implants

BACKGROUND: Increasing numbers of posterior pelvic ring fractures, especially in elderly patients, demonstrate the need for soft tissue protecting surgical techniques. Standard of care is iliosacral screw osteosynthesis. This type of osteosynthesis has its limitations especially in patients with reduced bone properties. Therefore, the development of new and straightforward surgical techniques and implant designs is favorable. METHODS: Introducing this modular system for the posterior pelvic ring, known complications of iliosacral screw osteosynthesis, such as implant loosening and malpositioning may be reduced, due to innovative mechanical characteristics. RESULTS: The shown cases demonstrate the potential benefits of the system with a wide range of treatment options due to its modularity. CONCLUSION: The modular implant system presented here can significantly facilitate and improve the stabilization of posterior pelvic ring instabilities.
