Background Regional performance of the hypertrophied left ventricle (LV) in hypertrophic cardiomyopathy (HCM) is still incompletely characterized with studies variably reporting that the hypertrophied myocardium is hypokinetic, akinetic, or has normal function. Different imaging modalities (M-mode or two-dimensional echocardiography) and methods of analysis (fixed or floating frame of reference...

PURPOSE Multiple hereditary exostoses of the forearm typically form in the distal ulna, causing disturbances in the growth of the ulna and functional disability. Multiple hereditary exostoses inhibit the growth of the ulna, leading to an acquisition of a varus deformity in the radius, which sometimes leads to dislocation of the radial head, the development of limitations in the pronation-supina...

PURPOSE To identify factors that affect functional outcome one year after distal radial fracture treatment. METHODS 521 women and 121 men aged 16 to 92 (mean, 59) years with distal radial fractures underwent external fixation (n=123), open reduction and internal fixation (n=63), a combination of both (n=10), distal radial osteotomy for symptomatic malunion (n=90), or casting with (n=194) or w...

We used the Ilizarov method in seven patients with severe congenital radial club hands who had had previous wrist surgery, to correct residual shortening and bowing of the ulna together with recurrent wrist deformity. The mean age at operation was 6.5 years. The mean ulnar shortening was 5.3 cm and the mean angular deformity 42 degrees. The mean length gained was 51% of the original ulna. The m...

OBJECTIVE Considering that global left ventricular systolic radial strain is a sensitive technique for the early detection of left ventricular dysfunction due to antineoplastics and the analysis of segmental myocardial contractility, we evaluated this technique for early detection of trastuzumab-related cardiotoxicity by comparing it with cardiac structural damage. METHODS Groups of six mice ...

Radial longitudinal deficiency, also known as radial club hand, is a congenital deformity of the upper extremity which can present with a spectrum of upper limb deficiencies. The typical hand and forearm deformity in such cases consists of significant forearm shortening, radial deviation of the wrist and hypoplasia or absence of a thumb. Treatment goals focus on the creation of stable centraliz...

OBJECTIVE To determine the radiographic outcome in fractures of the distal radius treated with closed reduction and external fixation. DESIGN A retrospective study. SETTING The orthopedic department of National Taiwan University Hospital. PATIENTS Eighty-five consecutive patients (36 female, 49 male), average age 48 years, with fractures of the distal radius seen between March 1995 and Ju...

BACKGROUND Three previous studies have investigated the long-term outcome of radial osteotomy in the treatment of Kienböck disease. However, none used patient-based assessment. The purpose of this study was to investigate the long-term clinical and radiographic outcomes of this osteotomy, including the subjective evaluation of the patient with use of the Disabilities of the Arm, Shoulder and Ha...
