Giza, Egypt SUMMARY The orthopedic hind limb affections in dogs constituted 31.99 % of the admitted cases to the Surgery clinic, Faculty of Vet. Med. Cairo univ., while the corresponding percentage in cats was 11.70 % during the period from October 2010 to April 2013. Pelvic limb fractures accounted for 50.60 % of the orthopedic dog patients, whereas, pelvic limb fracture in cats represented 69.39%. Femoral fracture in dogs constituted 56.80% of pelvic limb fractures, whereas, femoral fracture in cats comprised 59.80 %. The highest proportion in femoral fracture in dogs was in midshaft fracture (46.10 %), while in cats was the supracondylar fracture (57.41 %). INTRODUCTION Orthopedic affections constituted a major problem among dogs and cats (Senna, 2001; Harari, 2002 and Ben Ali, 2013). The most common type of fractured long bones in dogs and cats was the femur and tibia (Harasen, 2003). Femoral fractures were traumatic in origin due to automobile accidents and occasionally pathologic as a result of primary or metastatic bone tumors (Ozsoy and Altunatmaz, 2005) . Femur fractures represented 45% of all long-bone fractures, a rate which was more than double that of other bones (Unger, Montavon and Heim, 1990 and Brinker, Piermattei and Flo's, 2006). The percentage of femur fracture was 29.94 %. Distribution of femur fractures according to anatomic regions were diaphyseal (73.21%), supracondylar (19.64 %), caput femoris (3.57 %), trochanter major (1.78 %) and collumn femoris (1.78%) as reported by Tercanlioglu and Sarierler (2009). The majority of femoral fractures (69 %) occurred at or below two years old (Kolata and Johnston, 1975; Braden, Eicker, Abdinoor and Prieur, 1994). The most common breeds of cats affected with bone disorders were Siamese, Egyptian Mau and
