[Purpose] The purpose of this study was to identify postural changes in adults who have adopted the habit of sitting with their legs crossed. [Subjects and Methods] The subjects were 232 adults in their 20s and 30s (84 males and 148 females). They were divided into 0-, 1-, 2-, and 3-hour or more groups by observing how much time per day they sat with their legs crossed while sitting on a chair....

Introduction Total knee replacement (TKR) is the standard treatment for end-stage osteoarthritis when conservative measures have failed. Previous attempts to study coronal plane patellofemoral kinematics have suffered from the patella being obscured by the components and/or metal artefact (1,2). The aims of this study were: 1) To develop an accurate and reliable technique to measure patellofemo...

Bladder duplication is a rare congenital anomaly which occurs in the sagittal or coronal plane and it can be associated with other anomalies. It has been previously classified as complete duplication of the bladder and urethra or incomplete duplication with two bladders and common urethra. However, complete duplication of bladder with a single urethra has been rarely reported. Herein, we presen...

A C-scan imaging facility has recently been added to the ultrasonic system in use at Moorfields Eye Hospital, London. The technique is explained and typical C-scans are presented to demonstrate the normal orbital fat and optic nerve, together with selected pathological conditions in the orbit. The C-scan facility permits imaging of the orbital contents in the coronal plane. This coronal plane i...

The aim of this study was to determine the extent of asymmetry of spinal segment mobility in canoeists. Moreover, the relationship between this parameter and racing speed was analyzed. The study included 18 canoeists with a mean age of 16.4 years. Mobility of cervical, thoracic and lumbar spine, in sagittal, coronal and transverse planes, was measured with the aid of a tensometric electrogoniom...

The aim of this study was to distinguish the individual bundles of the anterior cruciate ligament (ACL) using the Chinese Visible Human (CVH) dataset and images obtained by low-field routine magnetic resonance imaging (MRI) in the oblique and coronal planes. Sectional anatomical data of the knee were selected from the CVH dataset and reconstructed in 3D. MRI of normal knees was performed with a...

Total knee arthroplasty (TKA) is a common procedure with good survivorship and functional results. Optimal results are dependent on proper osseous cuts and soft tissue balancing. Soft tissue tensioning via the polyethylene spacer thickness is an important component of soft tissue balancing. Increased thickness increases soft tissue tension and, therefore, has the potential to increase stability...

INTRODUCTION Coronal plane distal humeral injuries are relatively rare. Numerous classification systems have been proposed as the complexity of these fractures has been realized. We in the present series of ten patients describe the surgical technique of Open Reduction and Internal Fixation of Coronal plane fractures of the distal humerus with headless compression screws performed using the ant...

Periacetabular osteotomy (PAO) is a complex surgical procedure to restore acetabular coverage in the dysplastic hip, and the amount of acetabular rotation during PAO plays a key role. Using computational simulations, this study assessed the optimal direction and amount of the acetabular rotation in three dimensions for a patient undergoing PAO. Anatomy-specific finite element (FE) models of the...

BACKGROUND This study was to assess the accuracy of measuring the tibial and talar components position and to investigate the outlier rate of each component and predisposing factors related to component malalignment after total ankle arthroplasty (TAA) using a conventional method. METHODS One hundred fifty consecutive primary total ankle arthroplasty were performed using the three-component H...
