We analysed the short-term outcome after varus osteotomy for Perthes' disease in 48 older children from south-west India, comparing them with 30 historical controls. The children were between 7 and 12 years of age at the onset of the disease. All had stage-I or stage-II disease, with half or more of the epiphysis involved. The operated children had an open-wedge subtrochanteric varus osteotomy ...

PURPOSE The aim of this study was to determine differences in bat swing kinematics in baseball hitters of varying ability. METHODS Kinematic data for the upper and lower body were collected from 20 trained male baseball players (22.3 ± 5.3 yr, 1.82 ± 0.07 m, 83.5 ± 10.9 kg), using three-dimensional computerized motion-analysis techniques. Participants were ranked before testing based on a nov...

A rare combination of an ulnar fracture with posterior dislocation of the head of the radius and fracture of the radius shaft concomitant with an ipsilateral scaphoid fracture is presented. To the best of our knowledge, no such case has been reported. The mechanism of this fracture combination is discussed with respect to its role in producing the Monteggia type II fracture. Treatment consisted...

BACKGROUND Surgical excision of the radial head is frequently required after a comminuted fracture of the radial head. The outcome of this procedure is often unpredictable, with some patients experiencing ulna-sided pain in the wrist secondary to proximal migration of the radius. Insertion of a radial head prosthesis could prevent proximal radial migration and restore normal load-sharing at the...

This article reviews acute dislocations of the distal radioulnar joint (DRUJ) and distal ulna fractures. Acute dislocations can occur in isolation or in association with a fracture to the distal radius, radial metadiaphysis (Galeazzi fracture), or radial head (Essex-Lopresti injury). Distal ulna fractures may occur in isolation or in combination with a distal radius fracture. Both injury patter...

BACKGROUND AND AIM Permeation of a vein or lymphatic vessel by a tumor is a key risk factor for lymph node metastasis. We examined the features of colorectal tumor vessel permeation using endocytoscopy, an ultra-high magnifying endoscopic system combined with a narrow-band imaging capability (EC-NBI). PATIENTS AND METHODS We examined 188 colorectal lesions using EC-NBI before treatment was st...

Research into the genetic effects and specific genes associated with retinal vascular caliber, a risk marker of cardiovascular diseases, may provide new insights into the genetic contribution of early microvascular disease. A combined 374 monozygotic and 536 dizygotic twin pairs and 322 siblings from the Twins Eye Study in Tasmania and the Brisbane Adolescent Twin Study underwent complete ophth...

PURPOSE Subtle changes in retinal vascular caliber have been shown to predict diabetic retinopathy and other diabetic complications. This study was undertaken to investigate whether retinal vascular caliber correlates with light-flicker-induced retinal vasodilation, a measure of endothelial function. METHODS The participants were 224 persons with diabetes (85 type 1 and 139 type 2) and 103 pe...

The humeral head articulates with the glenoid fossa of the scapula. The anatomical neck separates the greater and lesser tuberosities from the humeral head. The long head of biceps runs between the tuberosities in the bicipital groove, and the surgical neck is just below the greater and lesser tuberosities. The radial nerve runs posteriorly around the middle third of the humeral shaft in the sp...
