OBJECTIVE To establish an optimal single hinge axis position for application of hinged external fixation to the elbow joint. DESIGN Cadaveric biomechanical investigation. SETTING A customized motion transducer applied passive elbow motion to six cadaveric upper extremities. The instant rotation axis of the humero-ulnar articulation was determined from three-dimensional kinematic data acquir...
BACKGROUND Positive spinal regional and global sagittal malalignment has been repeatedly shown to correlate with pain and disability in thoracolumbar fusion. OBJECTIVE To evaluate the relationship between regional cervical sagittal alignment and postoperative outcomes for patients receiving multilevel cervical posterior fusion. METHODS From 2006 to 2010, 113 patients received multilevel pos...
Background. Since the introduction of robot-assisted navigation in primary total knee arthroplasty (TKA), there has been little research conducted examining the efficiency and accuracy of the system compared to computer-assisted navigation systems. Objective. To compare the efficiency and accuracy of Praxim robot-assisted navigation (RAN) and Stryker computer-assisted navigation (CAN) in primar...
OBJECTIVE The aim was to define the long term prognosis of isolated ventricular septal defect (VSD) with anteriorly malaligned outlet septum. DESIGN Cohort study. SETTING University hospital, tertiary medical care centre. PATIENTS Between July 1986 and June 1993, 63 patients were studied with an isolated VSD and anteriorly malaligned outlet septum (59 perimembranous; 4 muscular outlet). ...
Preoperative Performance of PROMIS in Patients With Patellofemoral Malalignment and Chondral Disease
BACKGROUND There have been a few reported cases of congenital great toenail dystrophy (GTND), described as a congenital malalignment of the great toenails. However, acquired GTDN is rare, and has not been documented extensively. This study aimed to describe the clinical features of 21 patients with acquired GTND. METHODS Twenty-one patients with acquired GTND who visited Yeouido St. Mary's Ho...
UNLABELLED BACKGROUND The purpose of this study was to assess the concurrent validity of alternative measures of frontal plane knee alignment, namely the radiographic anatomic axis and two clinical measures in patients complaining of knee malalignment as compared with the mechanical axis on full-length radiograph of lower limbs. METHODS The knee-alignment angle was measured in 100 knees of...
CONTEXT Although disorders of the patellofemoral joint are common in the athlete, their management can be challenging and require a thorough physical examination and radiologic evaluation, including advanced magnetic resonance imaging techniques. EVIDENCE ACQUISITION Relevant articles were searched under OVID and MEDLINE (1968 to 2010) using the keywords patellofemoral joint, patellofemoral p...
A standard skeletal traction technique was applied to each major segment of the appendicular skeleton of ten fresh dog cadavers. Opposition points and anchorage points for the application of traction were determined for each skeletal segment. Traction was exerted by means of a micrometric traction stand, connected to the limb by bands or a stirrup. Traction was applied to the antebrachium and t...
