The pelvic girdle was characterized by large, transversely-placed ilial wings. The femur was the longest bone of the skeleton and its fovea capitis was situated caudomedially between the epiphyseal line and the articular surface of the femoral head. A wedge-shaped patella articulated with the femoral trochlea. The bones of the crus were approximately half as long as the femur and consisted of t...

An oblique fracture of the distal third of the right metatarsus in a three-year-old dromedary heifer weighing about 300 kilograms was immobilized with a 4.5 mm broad-webbed 12-hole dynamic compression bone plate and two interfragmental compression screws. The animal showed slight lameness after 16 weeks of surgery that disappeared after removal of the plate. The result was quite encouraging and...

Laboratory mice provide a versatile experimental model for studies of skeletal biomechanics. In order to determine the strength of the mouse skeleton, mechanical testing has been performed on a variety of bones using several procedures. Because of differences in testing methods, the data from previous studies are not comparable. The purpose of this study was to determine which long bone provide...

When subjected to strains or strain rates higher than usual, the bone remodels to repair microdamage and to strengthen itself. During the initial resorption phase of remodeling, the bone is transitorily weakened and microdamage can accumulate leading to stress fracture. To determine whether short-term suppression of bone turnover using bisphosphonates can prevent the initial loss of bone during...

Freiberg's disease is a relatively rare condition with a multifactorial cause in which trauma and circulation must play a major but not solitary role. Once the condition presents itself, early treatment is geared toward reducing its symptoms and preventing progression. If conservative measures fail, many surgical options are available. One of these, the dorsiflexion osteotomy of the metatarsal ...

BACKGROUND Delayed unions or refractures are not rare following surgical treatment for proximal fifth metatarsal metaphyseal-diaphyseal fractures. Intramedullary screw fixation with bone autografting has the potential to resolve the issue. The purpose of this study was to evaluate the result of the procedure. METHODS The authors retrospectively reviewed 15 athletes who underwent surgical trea...

INTRODUCTION Freiberg's infraction is an osteonecrosis affecting the metatarsal head whose pathogenesis is not fully understood, although stress overloading by multiple microtraumas remains the most widely accepted cause. Operative treatment, by different techniques, is necessary when conservative treatment fails. PRESENTATION OF CASE A 31-year old woman presented with left foot severe pain, ...
