Background: This study aimed to determine whether Blumensaat's line, a consistently present radiographic feature delineating the peak of the femoral intercondylar fossa, could be used to assess for cranial tibial subluxation in canine stifles with cranial cruciate ligament disease.
Use of Blumensaat's line for assessment of cranial tibial subluxation in dogs with cranial cruciate ligament deficiency
Treatment of cranial cruciate ligament insufficiency and medial patellar luxation in a small-breed dog with a true spherical osteotomy
A 9-year-old, neutered, male, Cairn terrier dog presented with a 3-year history of progressive pain and lameness of the right hindlimb. After an acute episode of severe pain and non-weight-bearing lameness, the dog was referred to our clinic for evaluation.
The physical examination was unremarkable; the orthopaedic examination revealed a positive cranial drawer sign and medial patellar luxation grade 3/4. Orthogonal radiographs were taken. Chronic degenerative changes consistent with cranial cruciate ligament insufficiency and medial patellar luxation were noted.
Evaluation of a screw insertion landmark for a minimally invasive repair technique in induced bilateral sacroiliac luxation in feline cadavers
Objectives: The aim of this study was to describe an alternative landmark for screw insertion into the body of the ilium with bilateral sacroiliac luxation in cats.
Tibial Tuberosity Transposition Fixation with a Locking Plate during Medial Patellar Luxation Surgery: An Ex Vivo Mechanical Study
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).
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.
