Abstract
Objective
This retrospective study assessed the complications and mid-term outcomes of osteosynthesis
using the String of Pearls Low Profile (SOP-LP) plate system in cats and small dogs
with appendicular fractures.
Methods
Clinical data from April 2018 to June 2021, involving 30 fractures in 29 cases, were
reviewed. Fractures were stabilized using either the 1.5-mm or 2.0-mm SOP-LP plate.
Data included patient signalment, fracture description, repair method, intraoperative
complications and short-term follow-up outcomes. Midterm follow-up was performed by
telephone-based veterinary questionnaires.
Results
Of the 30 fractures, 3 had complications linked to the SOP-LP system. Overall, 7/30
had complications. Major complications (n = 6) included two implant failures, one implant-associated irritation and three Kirschner
wire migrations. Implant failures (n = 2) were with the 1.5-mm plates stabilizing radius/ulna fractures in dogs weighing
over 2.9 kg. Short-term radiographic follow-up demonstrated clinical or radiographic
union in all cases. In all cases available (n = 18) for midterm follow-up, the function was found to be full or acceptable.
Conclusion
The SOP-LP plate can be used successfully for a wide variety of fractures in cats
and small dogs; however, careful case selection is required, particularly when using
the 1.5-mm plate as a single implant in patients weighing over 3 kg.
