The Fixion nail is an intramedullary nail made of stainless steel, that may be used to treat fractures of the humerus and in the lower limb. This nail is made up of a cylinder that has 4 longitudinal bars which, once inserted in the bone segment, expands via a pressure hydraulic system using physiological solution. The nail may be introduced without reaming(More)
PURPOSE The incidence of trochanteric fractures has increased significantly during the last few decades, especially in elderly patients with osteoporosis. The dynamic/sliding hip screw and the cephalomedullary nail are the most commonly used fixation methods to treat trochanteric fractures. The improvements in the Gamma Nail System (GNS) associated with a(More)
We report on two cases of simultaneous asymmetrical bilateral hip dislocation. Both patients were involved in car accidents. The first case is a 23-year-old man who had a bilateral hip dislocation, anterior on the right side and posterior on the left associated with bilateral femoral head fracture. The second case presented the same dislocations of the hips(More)
One hundred and forty patients underwent 142 brushings and conventional biopsies of suspected malignant lesions of the lung through a fibreoptic bronchoscope. Both samples were taken from the same area. One hundred and three patients showed positive results on brushing and 90 on biopsy. Thirty-nine diagnoses were negative on brushing and 52 on biopsy.

INTRODUCTION Multifocal humeral fractures are extremely rare. These may affect the neck and the shaft, the shaft alone, or the diaphysis and the distal humerus. There is no classification of these fractures in the literature. MATERIALS AND METHODS From 2004 to 2010, 717 patients with humeral fracture were treated surgically at our department. Thirty-five(More)
Nonunion of the subtrochanteric region is usually secondary to incorrect surgical treatment. The main cause of failed osteosynthesis is related to interruption of the medial cortex of the femur. Either a closed method, with intramedullary nailing, or an open method, using cortical osteosynthesis and opposing bone graft, may be used to treat the pathology.(More)
Femoral neck fractures are progressively increasing, due to higher survival rates, particularly among the female population. The gamma nail was created to treat intertrochanteric fracture types 31-A1, 31-A2 and 31-A3 and in some cases basicervical fractures of type 31-B2-1. Complications can be classified as intraoperative and postoperative. The(More)
INTRODUCTION Bleeding associated with pelvic fracture mostly comes from the pre-sacral and lumbar venous plexus, or directly from the fracture site. Bleeding as a consequence of arterial lesion is less common (15-20%), and that resulting from lesion of the external iliac artery (EIA) is extremely rare. The mortality rate associated with iliac artery injury(More)
Posterior wall fracture is the most common acetabular fracture. Comminuted fractures with an impacted segment represent a subtype of this injury. The subchondral bone of the articular zone is compressed and causes a bone defect. The impacted fragment should be isolated, mobilized, and then reduced. A bone graft should be used to fill the gap. The other(More)
Acetabular fractures are often associated with dislocation of the femoral head. When the dislocation is reduced, > or = 1 fragments may remain inside the joint, especially in posterior dislocation. In this kind of dislocation, the fracture of the posterior wall of the acetabulum may be comminuted. The fragments attached to the joint capsule or free may(More)
