Data Trace Editor – See: – Avascular Necrosis of Femoral Head: – Blood Supply to Femoral Head & Neck: – Non-Union following Femoral Neck Frx; – Discussion: – when femoral neck frx occurs, intraosseous cervical vessels are disrupted; – incidence of AVN in undisplaced fractures is 11%; … Read more
– Discussion: – local or Split compression frx have centrally depressed fragments; – AVN is diagnosed when serial X-ray show a gradual shrinking of the eleveated fragments until a defect remains; – surgically elevated articular fragments always are avascular; – fortunately most elevated frags regain vascularity before they … Read more
– Discussion: – prognosis: – perhaps the cause of the AVN in the most prognostic feature of whether or not core decompression will work; – an alcoholic who has 100% abstained from drinking might fare better than a transplant patient who requires continuous steroids; – bone grafting: – some type of bone grafting should … Read more

Discussion oral hypoglycemic agent which allows once a day dosing; usual dose is 4 mg PO qd but 8 mg PO qd is required in some cases;
– See: – Frx Dislocations of the Hip – Avascular Necrosis of the Femoral Head – Discussion: – overall incidence between 5-40%; – if reduction is performed w/in 6 hours, incidence of AVN will be less than 10%; – in the study by McKee, et … Read more
– See: AVN in Adults – Discussion: – results from forced attempts at reduction and subsequent disruption of the blood supply to the growing femoral head; – is reported to occur in 6-30% of patients undergoing closed reduction, but in some series the incidence can be as high … Read more

Background By way of background, I performed eight autologous hamstring resurfacing arthroplasties during the later half of 2007 at Franklin Regional Medical Center. This procedure involves harvesting the gracilis and semitendinosus tendons and rigidly oppossing them to the medial femoral condyle using knotless absorbable bone anchors for fixation. The drill holes for the bone anchors serve as a … Read more
