Abstract
Objective: To compare the efficacy of reduction, time to union, and clinical outcome of radius and ulna fractures stabilized using either minimally invasive plate osteosynthesis (MIPO) or open reduction and internal fixation (ORIF).Study Design: Retrospective, case‐controlled study.Animals: Dogs with radius and ulna fractures stabilized with plates applied usingMIPO(n = 15) orORIF(n = 15).Methods: Dogs in each stabilization group were matched for type and location of fracture, age, and body weight. Outcome measures including surgical time, fracture alignment, gap width, plate length, plate bridging and span ratio, working length and screw density, and time to union were compared between the groups using an unpaired t‐test. Statistical significance was set atP< .05.Results: All fractures obtained radiographic union although infection developed in 1 dog in each stabilization group. Dogs treated withMIPOhad a significant longer plate working length and lesser screw‐density (P< .05). No statistical difference was found in operating time, postoperative alignment, gap width, or time to union (MIPO: 51.9 ± 18.4 days;ORIF: 49.5 ± 26.5 days).Conclusions: Radius and ulna fractures managed withMIPOhad similar alignment, reduction, and time to union as fractures managed withORIF. Future prospective clinical studies are warranted and should assess healing more frequently and in a standardized manner to compareMIPOtoORIFin a larger population of dogs.
