– Discussion: – determine required thickness for the STSG: – since a thick STSG graft harvested from donor site w/ a thin dermal thickness, may lead to a full thickness wound, as well as causing hyperpigmentation of the transplanted STSG; – thick donor sites: posterolateral … 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
– Discussion: (see fracture healing and management of tibial bone defects) – autograft: bone graft harvest techniques – allografts – induced membrane technique – bone marrow aspirates: – in order to maximum the concentration of osteoblast precursors, no more than 2 cc should be … Read more

– Discussion: (see cartilage menu) – chondrocytes occupy lacunae distributed through the matrix; – chondrocytes are spherical in deep portion, but are flattened toward the periphery of cartilage; – peripheral lacuna may house a single chondrocyte; – deeper lacunae may contain two or more … Read more
– See: Skin Prep – Discussion: (chloroprep) – kills cells by disrupting their cell membranes and precipitating cell contents; – it has extremely low toxicity even when used on the intact skin of new borns; – in comparison to alcohols, antibacterial activity of chlorohexidine gluconate is not as rapid, but the drug remains … Read more

– Discussion: – general discussion of allograft tissue: – as pointed out by Harner et al. (1996), subjective knee scores were slightly better for knees having ACL – bone patellar bone allograft (as compared to BPB autograft patients) – objective ratings included normal (or nearly normal) … Read more
– see bone graft menu – Discussion of Allografts: – see autograft menu and bone healing: – allografts are most indicated when bone grafting is required along with need for mechanical structural support; – morselized bone graft: – structural bone grafts: – fresh allografts – generally … Read more
Autogenous bone graft remains the most effective treatment for fracture non unions, pseudoarthroses and for optimizing the success rate of arthrodesis. It is safer and more effective than artificial hydroxyapatite materials or allograft. The Acumed bone graft harvesting instruments facilitates safe, rapid harvest of morsellized autogenous graft through a small skin incision which minimizes the … Read more
