Ideal fixation technique for unstable fragility fractures of the sacrum
Recently, the management of fragility fractures of the pelvis has gained increasing attention. Rommens and Hofmann have introduced a comprehensive classification of these fracture patterns with increasing instability from grade I to IV[1]. U- and H-shaped fractures of the sacrum (FFP IVb) are the fractures with the highest instability due to a complete spinopelvic dissociation[2]. Non-operative treatment may be associated with impaired walking abilities, chronic pain, and the potential loss of independence. However, different treatment options are still controversially debated. The aim of surgical treatment includes sufficient fracture stability for immediate full weight bearing and good pain control postoperatively. A new surgical treatment algorithm was developed[3], suggesting the surgical fixation of FFP IVb fractures with two transiliac-transsacral screws (TI-TSS) in the first intact corridor cranial to the horizontal fracture pattern or lumbopelvic fracture fixation combined with one TI-TSS. However, the biomechanical stability of the different fixation techniques has not been evaluated.
Tissue Engineering Approaches to Study Tendon Injury, Disease, and Therapy
Join a dynamic research team at the intersection of biomechanics, tissue engineering, and cell biology. This project offers hands-on training in state-of-the-art methods to investigate how tendon tissue responds to injury, disease processes, and mechanical stimulation during exercise-based therapy.
