Minimally invasive transiliac anatomical locking plate for posterior pelvic ring injury: A technical trick of the gull wing plate.

Posterior pelvic ring injuries commonly involve sacral fractures, which are difficult to reduce and stabilize. Because conservative treatment requires long-term bedrest and leads to unsatisfactory outcomes, surgical intervention is a beneficial option to protect neurological structures and provide sufficient stability for early mobilization. Several studies have investigated a variety of internal fixation techniques, such as iliosacral screws, transiliac bars, spinal instruments, and transiliac plates. The gull wing plate (GWP) is a pre-contoured anatomical locking plate with two cancellous screws (φ6.5 mm) and four locking screws (φ5.0 mm), the design of which is unique among posterior tension-band plates. The GWP provides reliable stability of the posterior construct of the pelvic ring and accelerates rehabilitation. Compared to alternative surgical techniques for posterior fixation, the simple surgical procedure of the GWP is minimally invasive and highly reproducible, which leads to fewer complications and less radiation exposure.
