The purpose of this study was to investigate glenohumeral translation in-vivo during active shoulder abduction in the scapular plane. Three-dimensional (3D) models of 9 shoulders were created from CT scans. Fluoroscopic views aligned to the plane of the scapula were recorded during active arm abduction with neutral rotation. 3D motions were determined using(More)
BACKGROUND Spontaneous healing potential and progression of osteochondritis dissecans of the capitellum have been unclear. HYPOTHESIS Healing potential is high in the early stage of osteochondritis dissecans and low in the advanced stage. STUDY DESIGN Case series; Level of evidence, 4. METHODS This retrospective study examines 39 patients with(More)
BACKGROUND Fractures of the proximal humerus are common and the repair of displaced fractures generally requires an operative approach. In elderly patients, osteoporosis makes internal fixation problematic and frequently contributes to failed fixation and poor clinical results. We have developed a new intramedullary nail (pin lock nail) for the repair of(More)
We studied femoral head lesions resulting from applying excessive mechanical stress to the hip joints of ordinary growing Wistar Kyoto rats by forcing them to stand. Twenty rats were fed in high and low cages 5-15 weeks after birth. High rat cages were prepared with the feeding apparatus placed up high so that the rats had to stand on their hindlimbs to(More)
OBJECTIVE It has been shown that dietary whey protein accelerates glucose uptake by altering glycoregulatory enzyme activity in skeletal muscle. In the present study, we investigated the effect of dietary whey protein on endurance and glycogen resynthesis and attempted to identify plasma proteins that reflected the physical condition by a comprehensive(More)
BACKGROUND Surgical treatments have been selected to treat advanced osteochondritis dissecans (OCD) of the humeral capitellum. PURPOSE To evaluate the clinical results of surgical treatments for advanced capitellar OCD lesion and to clarify problems of poor clinical results. METHODS Cases were reviewed for 27 patients with advanced OCD lesions treated(More)
Osteonecrosis of the epiphyseal nucleus of the femoral head, which resembles that in Perthes' disease in children, was studied in spontaneously hypertensive rats (SHRs) and ordinary Wistar Kyoto rats (WKYs). The SHRs were kept in ordinary cages and the WKYs in custom-made high cages from 5 weeks to 15 weeks after birth. The WKYs had to stand on their hind(More)
Scapula-45 is an original roentogenographical technique to clarify objectively the function of the rotator cuff and scapulothoracic joint. This examination enables assessment of the function of the rotator cuff and scapulothoracic joint utilizing the radiographs of the glenohumeral joint. However, in the former technique, it was difficult for the technician(More)
