Objectives: The purpose of this study was to compare the load at failure, stiffness and mode of failure between three types of tibial tuberosity transposition fixation techniques: (a) pin and figure-8 tension band wire (Pin-TBW), (b) locking plate with pin and a tension band wire (Plate-Pin-TBW) and (c) locking plate with a pin (Plate-Pin).
Tibial Tuberosity Transposition Fixation with a Locking Plate during Medial Patellar Luxation Surgery: An Ex Vivo Mechanical Study
Accuracy of a drilling with a custom 3D printed guide or free-hand technique in canine experimental sacroiliac luxations
Objective: To improve the accuracy of drilling during the repair of sacroiliac luxations (SILs) with a 3D-printed patient-specific drill guide (3D-GDT) compared to free-hand drilling technique (FHDT).
Study design: Blinded, randomized, prospective ex vivo study.
Sample population: Sixteen canine cadavers (20-25 kg).
Proximodistal and caudocranial position of the insertion of the patellar ligament on the tibial tuberosity and patellar ligament length of normal stifles and stifles with grade II medial patellar luxation in small-breed dogs
Objective: To assess the role of the proximodistal and caudocranial relative position of the patellar ligament insertion on the tibia and patellar ligament length-to-patellar length ratio (PLL:PL) in small-breed dogs with and without grade II medial patellar luxation (MPL).
Study design: Retrospective study.
Sample population: Dogs weighing ≤15 kg, including 43 stifles with MPL and 34 control stifles.
Morphological Analysis of Bone Deformities of the Distal Femur in Toy Poodles with Medial Patellar Luxation
Objective: The aim of this study was to evaluate the bone deformities of the distal femur of Toy Poodles with medial patellar luxation (MPL) using computed tomography.
Complications and outcomes of cats with coxofemoral luxation treated with hip toggle stabilization using ultrahigh-molecular-weight-polyethylene or nylon (2009-2018): 48 cats
Objective: To report overall rate and type of complications and outcomes of cats with coxofemoral luxation managed with hip toggle stabilization (HTS), to compare rate of postoperative complications and outcomes of cats treated with ultrahigh-molecular-weight-polyethylene (UHMWPE) or nylon, and to identify risk factors for reluxation and non-excellent outcomes.
Study design: Multi-institutional retrospective cohort study.
Despite being one of the most commonly diagnosed causes of canine hind limb lameness, the pathogenesis of medial patellar luxation remains incompletely understood. Most cases are considered developmental with anatomical deformities leading to failure of the stifle extensor mechanism. These include coxa vara, coxa valga, reduced anteversion angle, distal external femoral torsion, excessive distal femoral varus, internal proximal tibial torsion, proximal tibial valgus, tibial tuberosity medialisation, patella alta and shallow trochlear groove.
Case description: A 7.5-year-old 37.8-kg (83.2-lb) sexually intact male German Shepherd Dog (dog 1) and a 2.6-year-old 28.2-kg (62.0-lb) sexually intact male Dutch Shepherd (dog 2), both apprehension police dogs, were admitted for evaluation of left and right thoracic limb lameness, respectively.
Transarticular elastic external skeletal fixator correction of a stifle rotational deformity and patellar luxation in a dog
Objective: To report the preoperative evaluation, treatment with transarticular elastic external skeletal fixation (ESF), and outcome of a dog with bilateral medial patellar luxation (MPL) and stifle rotational deformity.
Animal: One nonambulatory, 2.5-month-old, 7.5-kg mixed-breed intact female dog.
Risk factors for reluxation after toggle rod stabilization for treatment of coxofemoral luxation in 128 dogs
Objective: Evaluate the risk factors for reluxation and outcomes for dogs with a toggle rod construct.
Study design: Retrospective case series.
Animals: One hundred twenty-eight client-owned dogs.
