STSG Donor Site

– 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

Classification of Acetabular Defects and Bone Grafting Options

– See:       – Total Hip Replacement Menu:             – Acetabular Component Revision              – Femoral Bone Grafting for THR              – Frozen Allograft             – Dysplastic Hip – Discussion:     – in planning of acetabular reconstruction, major goal is to establish … Read more

Chondrocyte

– 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

Articular Cartilage: Injury and Potential for Repair

– See:        – Chondral and Osteochondral Injuries of the Knee        –  Enchondral Ossification         – osteochondral allografting for OCD injuries of the knee Healing of Articular Cartilage in Intra-Articular Fractures in Rabbits.  Viability and apoptosis of human chondrocytes in osteochondral fragments following joint trauma The viability of articular cartilage … Read more

Allograft Bone Patellar Bone Reconstruction

– 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

Allografts

– 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

Acumed Bone Graft System

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
