Idiopathic condylar resorption almost exclusively affects women. Its exact etiology and pathogenesis remain unclear. It has been associated with rheumatoid arthritis, temporomandibular joint internal derangement, condylar fractures, connective tissue or autoimmune diseases, orthodontic treatment, and orthognathic surgery. In most cases, however, there is no identifiable precipitating event, hen...

Dynamic flow losses in the suction chamber are a significant factor in reducing screw compressor efficiency but can only be roughly estimated in compressor design due to the simplified methods of analysis used to account for them. Today, Computational Fluid Mechanics analysis may be used to estimate velocity, pressure, temperature and concentration fields within a screw compressor far more accu...

OBJECTIVE To compare minimally invasive dynamic hip screw (MIDHS) fixation with conventional dynamic hip screw (CDHS) fixation for treatment of intertrochanteric femoral fracture. METHODS Of the 66 participants in this double-blind study, 35 were randomised to MIDHS and 31 to CDHS fixation. Main outcome measurements were wound size, haemoglobin decrease, blood transfusion rate, pain score, an...

AIM Aim of this study was to compare the volume and the shape of mandibular condyles in a Caucasian young adult population, with different skeletal pattern. MATERIAL AND METHODS 200 Caucasian patients (15-30 years old, 95 male and 105 females) were classified in three groups on the base of ANB angle: skeletal class I (65 patients), skeletal class II (70 patients) and skeletal class III (65 pa...

Objectives: In this study we aimed to present our treatment results of intramedullary nailing of femoral shaft fractures with compressive nailing using proximal static hole and only distal dynamic hole with one screw. Methods: Forty-three patients who had a fracture of the femoral shaft were managed between 2005 and 2008 with intramedullary nailing and the use of only one screw for distal inter...

INTRODUCTION Breakage of the screws which may cause non-union or collapse of vertebral structures has been a complication of the pedicle screw fixation at a rate of 3-7 % [1-2]. Recently, flexible rods have been used for dynamic stabilization to avoid complications such as adjacent segment degeneration due to excessive stiffness of the spinal fusion by allowing intersegmental motion at the surg...

OBJECTIVE To determine the effect of reinforced calcium phosphate cement augmentation of the femoral neck defect created after dynamic hip screw removal in a cadaveric model. METHODS The lag screws of dynamic hip screw implants were inserted and subsequently removed in 8 matched pairs of cadaveric, osteoporotic femurs to create a femoral neck defect. One of each pair had the defect augmented ...

The mandibular condyle region which protects the middle cranial fossa from facial and jaw traumas has an excellent osteomuscular structure. Condylar structures reduce or limit the force of trauma. Most importantly, the condylar neck is the weakest part of the mandible and is easily fractured without dislocation. Generally, this mechanism prevents condylar penetration into the middle cranial fos...
