Abstract
Objective
Our study aims to describe the surgical technique for temporary transarticular immobilization
of the stifle joint using a locking plate and evaluate complications and outcomes.
Methods
The medical records of dogs and cats that underwent transarticular immobilization
of the stifle joint using a locking plate in two institutions from August 2018 to
January 2024 were retrospectively evaluated.
After managing the primary injury, a locking plate was contoured to fit the medial
surface of the distal femur and proximal tibia, limiting the implant to the distal
third of the femur and proximal third of the tibia, with immobilization at a 135 to
145-degree angle.
Results
Temporary transarticular immobilization of the stifle joint was performed in 16 stifle
joints in 14 patients, with two dogs undergoing bilateral surgery. The transarticular
implants were removed at a mean time of 55,86 ± 18,05 days postoperatively (median:
58, range: 27–96 days). No intraoperative complications were recorded. One major complication
was recorded in a Galgo Espanol with a patellar fracture and patellar ligament lesion
in which plate breakage was recorded 19 days after surgery, requiring early plate
removal and application of an orthosis for 3 weeks. Four minor complications were
recorded.
Clinical significance
Preliminary results suggest that a transarticular locking plate is effective for temporary
stifle immobilization, with a low morbidity and complication rate. Dedicated implants
should be developed to decrease the risk of plate failure.
