PURPOSE To report the short-term outcome of the low contact stress (LCS) patellofemoral prosthesis in 51 knees. METHODS 12 men and 37 women aged 23 to 79 (mean, 53.4) years underwent 51 consecutive LCS patellofemoral replacements. All patients had symptomatic isolated arthritis in the patellofemoral joint with well-preserved tibiofemoral compartments. All(More)
The management of Achilles tendon rupture is a much-debated subject. In recent years, there has been much interest in early postoperative mobilization. We present the results of our Achilles tendon repair technique and accelerated rehabilitation program. The technique we propose uses the strength of a 1-loop polydioxanone "suture frame" to enable(More)
Rats were trained to respond under a cyclic-ratio schedule of reinforcement composed of an ascending, followed by a descending, sequence of ratio values. Subjects were trained while exposed to 70 dB white noise, then tested while exposed to 70 or 90 dB white noise. Exposure to 90 dB white noise elevated the response function (p<.02). Naloxone was then(More)
The current study reports on the colloidal stabilities and emission properties of CdSe/ZnS quantum dot (QD) optical probes capped with a variety of thin, hydrophilic surface coatings as studied using confocal fluorescence correlation spectroscopy. These coatings are based on mercaptoethanol, mercaptopropionic acid (with and without conjugated(More)
BACKGROUND Open dislocations are infrequent, often associated with damage to the neuro vascular structures. We present an unusual case of an open antero-lateral dislocation of the elbow, which was not associated with any vascular or neural injury. CASE PRESENTATION A 34 year female dance instructor sustained an open dislocation of her elbow. Surgical(More)
A 6-year-old Asian boy, with propionic acidaemia, presented feeling unwell and complaining of pain in the right thigh. There was no history of trauma, but plain radiographs of the right knee (Fig. 1) demonstrated a transverse supracondylar femoral fracture, through osteopenic bone. The question of non-accidental injury (NAI) was raised; a skeletal survey(More)
