“…A composite technique utilising multiple pins secured to antibiotic-impregnated PMMA has been reported and provides a strong, stable, and highly versatile repair that can be employed for any sacral fracture configuration (Wilson, 2015). However, this construct is bulky and often prohibits complete closure of the epaxial musculature as well as forming a visible or palpable structure dorsally; while curing of the PMMA presents a risk for thermal injury to exposed nerve roots (Wilson, 2015). The implant bulk and impaired soft tissue closure theoretically increases the risk of postoperative infection (Wilson, 2015).…”

“…Current guidelines are particularly lacking in regard to the indication for surgical stabilisation of sacral fractures. Anecdotally, conservative therapy including analgesia and strict confinement may be appropriate in minimally displaced fractures or in Anderson type I or IV fractures due to their abaxial position and reduced risk for neurologic injury (Anderson & Coughlan, 1997; Wilson, 2015). Conversely, the presence of severe pain, neurologic deficits, an unstable fracture configuration, other injuries requiring surgical stabilisation and pelvic canal collapse represent strong indications for surgical stabilisation of sacral fractures in small animals (Wilson, 2015).…”

ObjectivesTo describe the clinical presentations, outcomes and complications associated with the use of dorsal transiliac locking plates to stabilise sacral fractures in dogs and cats.Materials and MethodsA single‐centre retrospective analysis of all patients that presented with sacral fractures between February 2017 and February 2023 that were managed surgically using paired dorsal transiliac locking plates. Twelve animals met the criteria for inclusion in a retrospective clinical case series. An owner questionnaire was employed to assess long‐term outcomes.ResultsEleven dogs and one cat with a mean age of 3.1 years (range 0.6 to 8.8) were included. Eleven patients presented following a motor vehicle accident and most were either non‐ambulatory (n=8) or displayed severe unilateral hindlimb lameness (n=4). Nine sacral fractures were considered Anderson type II and three Anderson type V. The plate fixation was augmented with additional surgical stabilisation in 11 cases. Eleven patients were ambulatory at discharge and all cases healed uneventfully without major surgical or postoperative complications. Long‐term follow‐up (>60 days) was available in 10 animals at a mean of 694 days (range 65 to 1805) and owner‐assessed outcomes via questionnaire were reported as good to excellent in all cases.Clinical SignificanceThe application of transiliac locking plates provided sufficient stability to facilitate sacral fracture healing with minimal clinical complications. This method represents a robust and safe option to stabilise sacral fractures in dogs and cats, offering an alternative to iliosacral lag screw fixation.

“…Treatment recommendations for this type of fracture depend on the clinical picture, fracture configuration and stability, and neurological dysfunction. A case series describes the repair of complex sacral fractures in five dogs and a cat using a composite technique whereby multiple large fixation pins were placed into readily available, relatively dense bone stock and secured with polymethylmethacrylate . This technique has been previously described for vertebral fracture repair, but not in the stabilisation of sacral fractures for which iliosacral lag screw fixation is traditionally used.…”

“…While the structure of the bone healing is unstable, the intramedullary nail has long been used as a fracture fixation device for tibia shaft fracture. The intramedullary nail is still being used in the veterinary field as needed [1, 2]. The widespread use of stainless steel, titanium, and other nondegradable metal materials is still regarded as the golden standard for the orthopedic implant.…”

A stable repaired fracture is the key factor responsible for the recovery of a damaged bone. The iron-based implant is one of the biodegradable metals that have been proven safe as a fracture fixation device. The objective of our experimental approach was to examine the potential of the iron-based implant as a biodegradable metal in tibia shaft fracture in sheep chronically. The samples used for this experiment were iron-based and stainless steel implants. Each had a diameter of 5 mm. These samples were analyzed through 3 phases which are material characterization, in vitro and in vivo examination. The samples were examined using a scanning electron microscope with energy dispersive spectrometer and X-ray diffraction. Based on the analysis carried out, the samples contained 90,02% and 60,81% Fe for iron-based implant and stainless implant, respectively. Both implants maintained high viability when being in contact with calf pulmonary artery endothelial cells, indicating that both implants had a minimum response to the cell in a hemocytometer and methyl tetrazolium (MTT) assay. The systemic effect of the implants was observed using hematology and blood chemistry examination. Data collection also shows that both implants also had a minimum response to the erythrocytes, leucocytes, blood chemistry, and blood mineral during the period of observation. Therefore, it could be concluded that the iron-based implant is tolerable for a period of 9 months. It also has the potential to be used as a biodegradable orthopedic implant.
