“…The improper length of stem can lead to loosening or displacement of the cement plug into distal medullary canal (Noble et al, 1988). The postoperative fracture risk also may increase with misplacement of the tip of stem because femoral fractures associated THA are mostly occurred near the stem tip related incorrect loading of this region (Liska, 2004). The isthmus was placed between 42.72% and 45.36 % below the top of dog femora in present study.…”

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. Özet Kangal ve Alman Çoban Köpeklerinin Proximal Femur Bölümünde Cavum Medullare'nin Geometrik ÖzellikleriProximal femur, fonksiyonel ve biyomekanik özellikleri nedeniyle morfolojik varyasyonlar gösterebilir. Bu varyasyonlar, total kalça protezinin femoral implant uygulamaları ve tasarım çalışmalarında araştırıcılar için önemlidir. Proximal femur'un morfolojik özelliklerine ilişkin olarak, caput femoris pozisyonu ve cavum medullare'nin geometrik varyasyonları öncelikli olarak incelenir.

“…These fissures were due to the proximal diameter stem incompatibility to the proximal diameter of the femur; canine latin prostheses even cemented have a larger proximal stem diameter than other commercial models leading to overpreparation of the femur canal by the surgeon, thus leading to microfissure formation. Other studies (Olmstead et al, 1983;Massat and Vasseur, 1994;Liska, 2004) report observation of the same fracture localizations and postoperative time of presentation. In this study, incidence of fractures and fissures were presented in either cemented or cementless systems with the same rate, which is in opposition to the report from Montgomery et al (1992).…”

“…It might be useful in resolution and revision cases of total hip prosthesis femoral fracture (Liska, 2004), in such cases where it is not possible to position a plate with bicortical screw insertion because of the presence of the stem inside the canal impeding the insertion of the screws (Murphy et al, 1997;Liska, 2004). This study opened the possibility for using the locking prosthesis in cases which processes of osseous resorption, aseptic loosening and fractures are the main issues.…”

The aim of this study was to modify canine coxofemoral prostheses and the clinical evaluation of the implantation. Fifteen canine hips and femora of cadavers were used in order to study the surface points of modification in prostheses and develop a perforation guide. Femoral stems and acetabular components were perforated and coated with biphasic calcium phosphate layer. Twelve young adult male mongrel dogs were implanted with coxofemoral prostheses. Six were operated upon and implanted with cemented canine modular hip prostheses, establishing the control group. The remaining six were implanted with a novel design of cementless porous tricalcic phosphate-hydroxyapatite coated hip prostheses. Clinical and orthopedic performance, complications, and thigh muscular hypotrophy were assessed up to the 120 th post-operatory day. After 120 days, animals with cementless prostheses had similar clinical and orthopedic performance compared to the cemented group despite the increased pain thigh hypotrophy. Animals that underwent cementless hip prosthesis evidenced more pain, compared to animals with cemented hip prosthesis that required longer recuperation time. No luxations, two fractures and two isquiatic neurapraxies were identified in the course of the study.

“…Both studies reported that elderly dogs undergoing THR may be at an increased risk of femoral fractures. According to Liska (2004) old dogs with osteopathies, previous hip surgery and iatrogenic fissures created during reaming are predisposing factors for femur fracture after THR. The overall incidence of femur fracture after THR was 2.9%.…”
