A new minimally invasive U-shaped lumbopelvic stabilization technique

Lumbopelvic stabilization is a surgical technique used frequently to treat lumbosacral fractures; however, it can also be used in revision cases, infections, or during deformity correction. However, the related soft tissue complication rates associated with open lumbopelvic stabilization are high. Different authors have recently reported minimally invasive surgical techniques. We developed a rigid minimally invasive technique for lumbopelvic stabilization. We present our technique and also present preliminary results from 10 cases. We did not observe soft tissue-related complications in any patient. Implant removal was performed twice, to release healthy disks and because of implant prominence. One patient required revision surgery because of implant loosening due to osteoporosis, and one patient required revision surgery due to screw cap loosening. Postsurgical mobilization was good in all patients without further injuries; however, polytraumatized patients were limited by additional injuries. Thus, minimally invasive U-shaped lumbopelvic stabilization is a useful technique combining the soft tissue-related advantages of minimally invasive surgical techniques as well as a theoretically very rigid construct caused by strong implants.
