“…Based on general orthopaedic principles, the maximum acceptable bone segment translation should leave at least 50% bone segment apposition at the level of the osteotomy line in the frontal plane to facilitate acceptable bone healing. 15 The mean APP value in groups K5O4, K10O4 and K10O6 was higher than 50%, while mean APP in group K5O6 was 39%. The less than 50% apposition documented in group K5O6 represents excessive translation of the proximal segment which might compromise bone healing in a clinical patient.…”

Objective The main aim of this study was to determine the effective magnitude of proximal tibial segment medialization achievable during tibial plateau levelling and medialization osteotomy (TPLO-M) with Fixin 1.9-2.5 mm pre-contoured T plates with three different offsets. Methods In this in vitro study, 36 tibia bone models reconstructed using stereolithography from hindlimb CT scans of a 5 kg dog and a 10 kg dog without orthopaedic disease were used. TPLO-M was performed using plates with three different offsets (2, 4 and 6 mm). Post-osteotomy radiographic and bone models measurements were performed. Results Regardless of patient weight, the +4 mm offset plates provided a translation of 2.93mm (± 0.51) while the +6 mm offset plates provided a translation of 5.03mm (± 0.47). In the 5kg dog bone model group limited bone contact at the osteotomy site was documented when using the +6mm offset plate. Conclusion The +4mm and +6mm offset Fixin plates may be considered for TPLO-M in dogs weighing between 5 and 10 kg. The +6mm offset plate should be used cautiously in dogs weighing less than 10 kg since this plate may result in insufficient postoperative bone apposition at the osteotomy site.

“…Although a more distal CORA is common in dogs with medial luxation, 24 the juvenile patients described here showed a more proximal CORA, preventing the closing wedge from conflicting with the physeal line of growth, which could potentially interfere with subsequent bone development. 8 Nevertheless, the osteotomy could be planned more proximally, with modifications related to the union of the bone fragments, 25 although there was no such need in our five patients.…”

Objective The aim of this study was to analyse a series of five cases of early surgical treatment in juvenile canine patients with high-grade medial patellar luxation. Study Design Canine patients, with immature skeleton, affected by grade III or IV medial patellar luxation and treated by multimodal surgical techniques were selected. Results Five dogs of different breeds, mean age 7.2 ± 3.0 months, met the inclusion criteria. Simultaneous distal femoral varus and external tibial torsion were identified in three of the five cases, whereas in the others, femoral varus with associated tibial valgus and isolated external tibial torsion were observed. Four of the five patients were treated surgically with closing wedge osteotomy of the distal femur, and three of them underwent tibial tuberosity transposition simultaneously. Only two animals required trochleoplasty. Mean time to beginning of weight bearing was 9.8 ± 5.5 days, whereas time to bone healing was 55 ± 24 days. Bone realignment of the extensor apparatus and return to limb support were achieved in all cases. Postoperative reintervention was needed in one patient; however, it was not linked to the initial surgery. Patients were followed up to 1 year postoperatively, with maintenance of extensor alignment and no late complications. Conclusion The early surgical approach has been shown to be effective in the definitive treatment of juvenile dogs affected by high-grade medial patellar luxation.

“…The determination of angular values helps in the characterization of orthopedic conditions 12 . In veterinary medicine, radiographic measurements have been applied mainly to dogs and cats, 13–15 but also wildlife such as crab‐eating foxes, 16 maned wolves, 17 capybaras, 18 and marmosets, 19 among others.…”

nigritus. 1 These are diurnal, medium-sized primates, with weights ranging from 1.4 to 4.8 kg and a semi-prehensile tail used during foraging, and capable of supporting body weight for short periods. 2,3 Locomotion is done by quadrupedal walking, climbing, and running. 3 Capuchin monkeys are considered the most intelligent primate of the Americas, with curious behavior while moving, removing, and breaking things. 4 Several imaging methods have been used in humans for investigating the dimensions of the maternal pelvis, but radiation exposure during x-ray pelvimetry is a concern. 5,6 The technique has been performed in some species of Neotropical monkeys to establish normal ranges and thus facilitate reproductive management and predict obstetric risks. [7][8][9] Plain radiographic images have also been used in humans to define and measure the alignment of the pelvic limbs through their physiological axes and mechanical and anatomic angles. 10,11 The determination of angular values helps in the characterization of orthopedic conditions. 12 In veterinary medicine, radiographic measurements have been applied mainly to dogs and cats, [13][14][15] but also
