“…Cortical Thickness Index is the ratio between the endosteal and outer diameters of the proximal femur at 10 cm below the lesser trochanter (Figure 3). It showed a strong correlation with the T score (r = -0.71, P<0.001) and the best overall performance in diagnosing osteoporosis (18). Finding a hip radiography with Cortical Thickness Index value ≤ 0.40 should be a caution to recommend referral for osteoporosis evaluation and bone mineral density testing (19,20).…”

SummaryOsteoarthritis is one of the most common joint disorder. For treatment of hip symptomatic osteoarthritis, when conservative medical therapy has failed, total hip arthroplasty (THA) is a successful orthopaedic procedures that reduces pain and improves function and quality of life. Incidence of osteoarthritis is constantly increasing with raising life expectancy. This aging process also has led to an increasing number of patients with osteoporosis who need hip replacement for osteoarthritis. Osteoporosis have 3 major potential complications in total hip arthroplasty: perioperative fracture, an increased risk of periprosthetic fracture, and late aseptic loosening. The purpose of the present study was to examine the effects of osteoporosis on total hip replacement procedure outcome and highlight the importance of adequate study of calcium-phosphorus metabolism in patient candidate for hip surgery, and the need to start a suitable therapy to recover the bone mass before surgery. Bone quality of the hip joint has become an important risk factor limiting the durability of THA.KEY WORDS: total hip replacement; bone metabolism; perioperative and periprosthetic fracture.

“…Other side cortical thickness is an important factor to proper canal preparation (Peck and MarcellinLittle., 2013) In studies about THA, the cortico-medullary index is generally calculated only at the midshaft or at the ishtmus regions and at the medio-lateral direction (Baharuddin et al, 2014;Noble et al, 2003;Palierne et al, 2006;Palierne et al, 2008;Umer et al, 2010;Yeung et al, 2006).

“…They are the most useful data for preoperative planning or postoperative evaluating of the femoral implant on THA studies. They are also easy to use to evaluate objectively proximal femoral geometry (Abadie et al, 2010;Breusch, 2005;Noble et al, 1988;Palierne et al, 2006;Palierne et al, 2008) as well as to assess cortical bone quality (Baumgartner et al, 2015;Yeung et al, 2006).…”

“…There have been some studies about race variances in human proximal femoral canal (Rawal et al, 2012;Tawada et al, 2015;Umer et al, 2010;Yang et al, 2014;Yeung et al, 2006), however, there is no adequate studies about it in dog breeds. Because of the great number of dog breeds the studies about breed-specific comparison may not possible for each breed (Palierne et al, 2008).…”

“…To the best of our knowledge there are incomplete data to evaluate variations in the geometry of the medullary canal of proximal femur in dog. The isthmus position index (IPI), the corticomedullary index (CMI) and the canal flare index (CFI) are the most useful bone indices to evaluate objectively proximal femoral geometry in respect to THA (Abadie et al, 2010;Breusch, 2005;Noble et al, 1988;Noble et al, 2003;Palierne et al, 2006;Palierne et al, 2008;Rawal et al, 2012;Umer et al, 2010;Yeung et al, 2006;Yang et al, 2014). The isthmus position is measured in human femur studies (Noble et al, 1998;Noble et al, 2003;Rawal et al, 2012;Sugano et al, 1998;Umer et al, 2010;Yang et al, 2014).…”

The proximal femur has morphological variability that is related to its functional and biomechanical properties. Therefore, researchers have long been interested in these variations especially associated with the femoral implant design and implantation in total hip arthroplasty. The positions of the femoral head and the geometrical variations in the medullary canal are evaluated in particular to understand the proximal femoral morphology. The position of head or neck of the dog has already been studied in detail. There are incomplete data to evaluate variations in the geometry of the medullary canal of proximal femur in dog. Proximal femoral morphology of the medullary canal has been evaluated only at the coronal plane in dog studies using plain radiography. The morphometric data on the sagittal plane are also need to innovations in femoral implants. The purpose of this study is to indicate the detailed geometric data about proximal femoral canal of dog using threedimensional morphometric methods to provide a database for the orthopedic studies. The effect of the breed with different pelvic limb conformation was also studied in this study. The cleaned femora from 16 German shepherd and 16 Kangal dogs were used. The threedimensional images were reconstructed from the computed tomographic images. The femoral length, the anteversion angle and neck angles, the isthmus position and the widths on medio-lateral and cranio-caudal directions of the cross-sections of proximal femur were measured. The cortico-medullary indices, the isthmus position index and the canal flare indices were also calculated to detailed investigation of medullary canal of the proximal femur. According to our study results, it must be considered in stem design that the level of the isthmus might change in response to different conformations of the dog breeds, whilst the flare indices are similar in the dogs. The flare of the medullary canal was firstly evaluated with the cranio-caudal diameters on the three-dimensional images in this study. The corticomedullary index shows some variation between the dog breeds across the levels and the directions of the cross-sections of the proximal femur. Nowadays, three-dimensional images can be acquired and morphometric measurements can be done easily by tomography in a lot of veterinary clinics. The data from three-dimensional morphometric analysis may contribute to the optimization of the design and preoperative selection of femoral implants by surgeons.
