Aim To find out if Doppler myocardial imaging (DMI) can detect early signs of left ventricular (LV) dysfunction in a rat model of diabetic cardiomyopathy. Methods Eight control and 12 Streptozotocin (STZ)-induced diabetic rats underwent transthoracic echocardiography with high-resolution technology at baseline and 2, 4, 8, 12, and 16 weeks after STZ injection. Radial function was analysed using...

A Monteggia fracture is a fracture of the proximal ulna coupled with a radial head dislocation. These fractures are an uncommon class of forearm fractures. Numerous classification systems have been developed to characterize these fractures, with the Bado classification being the most common. Elbow radiographs are the primary diagnostic modality, demonstrating dislocation when a line drawn exten...

BACKGROUND We evaluated the radiologic and functional outcomes of patients with radial head fractures managed with open reduction and internal fixation. METHODS Between 1998-2003, 15 patients (7 males, 8 females; mean age 34.1; range 18 to 49 years) with radial head fracture were treated with open reduction and internal fixation. Follow-up time was 54.6 months (42-78). Three fractures were Ma...

Recurrent deformity from centralization and radialization led to the development in 1999 of a new technique by the author called ulnarization. This method is performed through a volar approach in a vascular and physeal sparing fashion. It biomechanically balances the muscle forces on the wrist by dorsally transferring the flexor carpi ulnaris (FCU) from a deforming to a corrective force. The pr...

Using a volar approach to avoid the soft tissue problems associated with dorsal plating, we treated a consecutive series of 29 patients with 31 dorsally displaced, unstable distal radial fractures with a new fixed-angle internal fixation device. At a minimal follow-up time of 12 months the fractures had healed with highly satisfactory radiographic and functional results. The final volar tilt av...

Short and accurate analytic formulas for the Seidel coefficients of gradient-index lenses with arbitrary radial refractive-index distributions have been obtained. Starting from analytic ray-tracing formulas, we have developed a technique for decomposing the two components of the transverse aberration of an arbitrary skew ray in surface and inhomogeneous transfer contributions and a technique fo...

INTRODUCTION The anatomical variations of bones in the hand are common. The existence of exostosis and shortening of metacarpal bones has been described in the literature as part of the hereditary multiple exostosis syndrome but no case has been reported with the co-existence of sesamoid ossicles in the same patient. CASE PRESENTATION We report a case with co-existence of distal ulnar and rad...

Seven children who had partial arrest of the growth plate after neonatal arterial cannulation, developed obvious skeletal changes in adolescence. Cannulation of the femoral artery produced ischaemia which led to four cases of ipsilateral shortening of the lower limb and one of partial arrest of the proximal femoral physis with subsequent coxa valga. The two arrests in the upper limb affected th...
