Plain-English summary
A dog with a broken leg underwent surgery to fix a tibial fracture using a new method involving a custom 3D-printed guide. This technique, called minimally invasive plate osteosynthesis (MIPO), allowed for a quicker surgery and less use of X-ray imaging compared to traditional methods. Although the planning took longer before surgery, the actual operation was faster, and both methods resulted in similar healing outcomes. The dog recovered well, showing no significant differences in leg alignment or length after surgery.

Abstract
OBJECTIVE: To compare the efficacy and clinical outcomes of computed tomography (CT)-based virtual surgical planning (VSP) and a three-dimensional (3D)-printed, patient-specific reduction system to conventional indirect reduction techniques for diaphyseal tibial fractures stabilized using minimally invasive plate osteosynthesis (MIPO) in dogs. STUDY DESIGN: A prospective clinical study with a historic control cohort. SAMPLE POPULATION: Dogs undergoing MIPO stabilization of diaphyseal tibial fractures using a custom 3D-printed reduction system (3D-MIPO; n = 15) or conventional indirect reduction techniques (c-MIPO; n = 14). METHODS: Dogs were prospectively enrolled to the 3D-MIPO group and CT scans were used to design and fabricate a custom 3D-printed reduction system to facilitate MIPO. Medical records were searched to identify dogs for the c-MIPO group. Pre-, intra- and postoperative parameters were compared between groups. RESULTS: The duration from presentation until surgery was 23 h longer in the 3D-MIPO group (p = .002). Fewer intraoperative fluoroscopic images were acquired (p < .001) and mean surgical duration was 34 min shorter in the 3D-MIPO group (p = .014). Median postoperative tibial length, frontal alignment, and sagittal alignment were within 4 mm, 3° and 3°, respectively, of the contralateral tibia in both groups and did not differ between reduction groups (p > .1). Postoperative complications occurred in 27% and 14% of fractures in the 3D-MIPO and c-MIPO groups, respectively. CONCLUSION: Both reduction methods yielded comparable results. Although the preoperative planning and guide preparation was time consuming, surgery times were shorter and fluoroscopy use was less in the 3D-MIPO group. CLINICAL SIGNIFICANCE: VSP and the custom 3D-printed reduction system facilitated efficient MIPO.
