Repair of sacral fractures using pins and polymethylmethacrylate (six cases)

Case reports: Sacral fracture repair was accomplished in a cat and five dogs using a composite technique consisting of pins and polymethylmethacrylate (PMMA). In three of the cases, planned traditional iliosacral lag screw fixation was either abandoned or considered inadequate and in the other three, fracture configuration demanded an alternate repair method. All six cases healed uneventfully with no surgery-associated complications. To the author's knowledge, the use of a composite technique has been previously described for vertebral fracture repair, but not in the stabilisation of sacral fractures. Indications for the composite technique include failed iliosacral lag screw repairs, augmentation of a tenuous repair and any sacral fracture configuration not amenable to lag screw fixation. Conclusion: Composite repair is a versatile primary, ancillary or revision technique for sacral fracture fixation
