BACKGROUND AND PURPOSE Passing from the supine to the upright position favors cerebral venous outflow into vertebral venous systems rather than into the internal jugular veins. We sought to determine venous connections between dural venous sinuses of the posterior cranial fossa and craniocervical vertebral venous systems. METHODS Corrosion casts of the cranial and cervical venous system were ...
BACKGROUND Femoral component rotation (FCR) is one of the most important factors in total knee arthroplasty. In this prospective study, we used three different techniques for FCR and analyzed their accuracy with postoperative axial computed tomography (CT) images. We also evaluated effect of FCR to clinical outcome. METHODS One hundred sixty-five patients were randomly allocated into three gr...
The aim of this long-term study was to assess the amount and direction of glenoid fossa displacement, condylar growth, and "effective" temporomandibular joint (TMJ) changes (= the sum of glenoid fossa displacement, condylar growth, and condylar position changes in the fossa) in 3 vertical facial-type groups of Class II Division 1 malocclusions treated with the Herbst appliance. A comparison was...
Clinical limitations following closed reduction of an intracapsular condylar fracture include a decrease in maximum mouth opening, reduced range of mandibular movements such as protrusion/lateral excursion, and reduced occlusal stability. Anteromedial and inferior displacement of the medial condyle fragment by traction of the lateral pterygoid muscle can induce bone overgrowth due to distractio...
INTRODUCTION: Correct rotational alignment of the femoral component is one of the most important factors for successful total knee arthroplasty. The rotational position of the femoral component can be determined using bony landmarks, such as the transepicondylar axis, the posterior condylar axis, or the anteroposterior (AP) axis (Whiteside’s line). Rotational alignment of the femoral component ...
PURPOSE To measure the femoral posterior condylar cartilage (PCC) thickness and the posterior condylar offset (PCO) and determine the correlation between the 2 parameters in 530 normal subjects using magnetic resonance imaging (MRI). METHODS Records of 287 male and 243 female patients (mean age, 40.7 years) who underwent MRI for traumatic soft tissue knee injuries not involving the femoral PC...
The treatment of temporomandibular joint ankylosis poses a significant challenge because of the high incidence of recurrence .The only treatment option for TMJ ankylosis is surgical with or without condylar reconstruction. Various grafts are available for condylar reconstruction after removing the ankylotic mass such as costochondral, sternoclavicular, posterior border of mandibular ramus, fibu...
OBJECTIVE The purpose of this study was to evaluate the horizontal changes in the condylar head with bent plate fixation after sagittal split ramus osteotomy (SSRO) with and without a Le Fort I osteotomy. STUDY DESIGN Of 47 Japanese patients with mandibular prognathism, 24 underwent SSRO and 23 underwent SSRO in combination with a Le Fort I osteotomy. A 3-5-mm gap was made between the proxima...
OBJECTIVE To evaluate condylar head remodeling after mandibular set-back sagittal split ramus osteotomy (SSRO) with rigid fixation in skeletal class III deformities. The correlation between condylar head remodeling and condylar axis changes was determined using cone-beam computed tomography (CBCT) superimposition. METHODS The CBCT data of 22 subjects (9 men and 13 women) who had undergone man...
