“…For this reason, the geometry of proximal tibia has been studied in detail (Selmi and Filho 2001;Baroni et al 2003;Reif and Probst 2003;Reif et al 2004;Osmond et al 2006;Dismukes et al 2007 andBuote et al 2009). However, there is limited data on the geometry of the distal femur focusing on the intercondylar fossa Montgomery et al 1995;Comerford et al 2006;Sellmeyer et al 2007;Lewis et al 2008).…”

The stifle joint is one of the most important joints in dogs from the orthopaedic point of view. The aim of this study was to document the morphometric values of femoral condyles, given the close relationship between the shape and function of an anatomic structure. The left femora of 16 mid-sized dogs were used, and diameter and nine radii as well as cranial and caudal bow lengths from each condyle were measured. The photographs were taken of the distal femora from both sides. All measurements were obtained from these images by using software. Additionally, the rotation angle was calculated from the intercondylar distance and the difference between lateral and medial bow lengths. In addition to the rotation angle, the difference of diameter and nine radii between the lateral and medial condyles was determined. All radii except getting at 90° were significantly different between the medial and lateral condyles. The greatest values were determined in the caudal part of the medial condyle. This results the smaller contact area and a greater pressure on the underlying surface, and therefore the meniscus and articular cartilage of the caudal part of the medial side suggests the possibility of a risk of injury as the stifle joint flexes. The mean rotational angle of the femur was also calculated to be 2.18° laterally and 1.02° medially in the caudal and cranial parts of condyles, respectively. The result of this study showed that the lateral and medial condyles had different shapes in canine femur.

“…The distance between the medial surface of the calcaneal tuber and distal intermediate ridge of the tibia on the CC projection was measured. This distance was divided by the distance between the most proximal points of the 2 arciform grooves of the cochlea tali of the tibia and multiplied by 100 to give percentage distal tibial rotation (DTR) (Dismukes et al, 2007;Swanson et al, 2012). Values greater than 50% were considered to denote excessive rotation of the limb (positional or TT).…”

“…Apposition was recorded as good, adequate or unacceptable when dispersion was <50%, 50 -100% or >100% respectively. Alignment in the frontal plane was assessed by calculation of the mechanical medial proximal tibial angle (mMPTA) and mechanical medial distal tibial angle (mMDTA) (Dismukes et al, 2007) (Figure 2). Using these values the tibial varus-valgus angle (TVA) was calculated as previously described where TVA = [mMPTA + mMDTA] -180 (Guiot & Déjardin, 2011).…”

Objective: Describe the clinical findings and management of tibial fractures in cats in which plate osteosynthesis failed due to plate bending.Study Design: Multicentre, retrospective clinical study. Methods:Clinical histories and radiographs of 10 cats that suffered plate bending following plate or plate-rod fixation of tibial fractures were reviewed for signalment, fracture configuration and repair, post-operative and post-failure tibial alignment, ultimate treatment and outcome. Tibial alignment post-operatively and post-failure was compared using a paired T-test.Results: Mean age was 5.3 years and mean body weight was 5.0kg. All ten cats sustained complete fracture of the tibia with an accompanying fracture to the fibula. Tibial fractures were generally oblique (4/10) or spiral (4/10) with mild comminution (8/10) and located in the middle (3/10) or distal (6/10) third of the tibia. Initial fracture stabilisation was with a plate (6/10) or plate-rod combination (4/10) with the plate applied to the medial tibial surface. Non-reduced, lateral tibial wedge fragments were present in 5 fractures. Mean time to implant failure was 24 days. Mean tibial valgus angle increased from 12.9° to 30.9°

“…O emprego de radiografias em projeção ventrodorsal possibilita aferir os eixos mecânico e anatômico de ossos longos e seus ângulos de orientação articular, que são medidas importantes nos casos de deformidades ósseas em cães (FOX et al, 2006;DISMUKES et al, 2007). Na medicina felina, poucos são os estudos referentes a este tipo de metodologia, dificultando o aprofundamento dos cirurgiões na planimetria de procedimentos ligados a defeitos angulares nessa espécie (SWANSON, 2012).…”
