Introduction: When compared with other long bone fractures, femoral fractures are reported to have the highest rates of osteomyelitis and non-union development. Fracture repair using minimally invasive plate osteosynthesis (MIPO) methodology is being used more frequently in veterinary medicine. The objective of this study was to describe non-articular femoral fracture repair in dogs using MIPO methodology, and to compare radiographic measurements between femora receiving MIPO fracture repair and unaffected, contralateral control limbs.

Materials and Methods: Femoral fractures repaired utilizing MIPO methodology were retrospectively reviewed. Orthogonal femoral radiographs were used to quantify femoral length, femoral torsion, anatomical lateral proximal and distal femoral angles (aLPFA and aLDFA), respectively. These values were compared with values of the normal contralateral femur. Healing times and post-operative complications were recorded at scheduled recheck examinations.

Results: Twelve dogs met inclusion criteria. Successful reduction and radiographic union of comminuted femoral fractures was achieved in all dogs. Mean time to follow-up was 69 days and the mean time to radiographic healing was 83 days. Femoral version angles were significantly greater in the MIPO repaired femora when compared with the contralateral femora (p = 0.01). No significant differences were detected in aLPFA, aLDFA, femoral length, or inclination angle between femora receiving MIPO fracture repair and the control limbs.

Discussion/Conclusion: MIPO was used successfully to repair comminuted femoral fractures in all dogs. Pre-operative templating and contouring of the plate helped restore frontal plane alignment and femoral length. We suspect that the reduced exposure to anatomical landmarks affected the ability to restore anatomical version angles.
