– See: Total Hip Replacement Menu: and see total knee replacement infections – Diagnosis: – diagnosis of septic loosening is initially based on history, x-ray findings, and elevated sed rate; – clincially patients may note increasing pain at both rest and with activity; – despite the variety of tests available, it may be difficult to distinguish … Read more
– Age: – physiologic age < 60 yrs in an athlete, laborer, or anyone who needs to knee down such as for gardening (remember that a TKR will generally not allow the patient to kneel); – Angular Deformity: – less than 15 deg of fixed varus deformity (often patients will … 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 oppossing them to the medial femoral condyle using knotless absorbable bone anchors. The drill holes for the bone anchors serve as a source for hematopoetic … Read more
– Discussion: – a common benign but locally aggressive lesion of unknown etiology; – occurs chiefly in men between 20-50 yrs (after epiphyseal closure); – tumor is expansile lytic lesion that involves the epiphysis & metaphysis; – tumor may enlarge to occupy most of epiphysis & adjacent metaphysis; … Read more
– Discussion: – Fibular Harvest: – Hip Preparation: Various methods have been advocated for the treatment of acascular necrosis of the hip in the young patient. From the literature an operative treatment for the symptomatic hip is the conservative method of management. Reports on core decompression, osteotomies, electrical stimulation, and bone grafting have been difficult … Read more

– Discussion: – results from a defect is somatic mutation in the gene coding for alpha subunit of Gs, the G protein that stimulates cAMP formation; – overproduction of cAMP, causes overexpression of c-fos, which regulates proliferation and differentiation of osteoblasts and osteoclasts; – results in … Read more
– See: TKR Menu / Supracondylar Femur Frx – Discussion: – known risk factors include notching of the femur, osteoporosis, and excessive polyethylene wear (w/ subsequent osteolytic defect) – other risk factors include osteonecrosis of the femur; – ref: Morphologic analysis of periprosthetic fractures after hip resurfacing arthroplasty. – Radiographs: – often oblique radiographs are needs … Read more
– See: – Total Hip Replacement Menu: – Acetabular Bone Grafting: – Allografts – Discussion: – indicated for pts w/ severe osteolysis or for femoral shaft fractures; – in younger pts, structural allografting may eventually allow some … Read more
