abnormal lateral tibiofibular ratio is reliable way of diagnosing ER rotation stress view. Diagnosis is generally made with MRI studies to evaluate for bone marrow edema or subperiosteal abscess. His bloodwork shows elevated ESR.
MRI of the right foot can be seen in Figure A. A material with either osteoconductive, osteoinductive, and/or osteogenic properties, almost 1 million bone grafting procedures performed in US each year, with a growth of almost 13% per year, healing of fractures, delayed unions, or nonunions, replace bone defects from trauma or tumor, relative resorption rates of bone graft substitutes, calcium sulfate > tricalcium phosphate > hydroxyapatite, retrieval studies are helpful in understanding the body's response to allografts, allograft articular cartilage is completely acellular, Bone graft has aspects of one or more of these three properties, material acts as a structural framework for bone growth, the various three-dimensional makeups of the material dictate the conductive properties, material contains factors that stimulate bone growth and induction of stem cells down a bone-forming lineage, material directly provides cells that will produce bone including primitive, mesenchymal stem cells, osteoblasts, and osteocytes, mesenchymal stem cells can potentially differentiate down any cell line, osteoprogenitor cells differentiate to osteoblasts and then osteocytes, cancellous bone has a greater ability than cortical bone to form new bone due to its larger surface area, autologous bone graft (fresh autograft and bone marrow aspirate) is the only bone graft material that contains live mensenchymal precursor cells, Allograft is a composite material and therefore has many potential antigens (cell surface glycoproteins), Class I and Class II antigens on graft are recognized by host T lymphocytes and elicit an immune response, immunogenic cells are marrow-based, endothelium, and retinacular-activating cells, bone marrow cells elicit the greatest immune response, extracellular matrix also acts as an antigen, type I collagen stimulates both humoral and cell-mediated responses, noncollagenous matrix (proteoglycans, osteocalcin), hydroxyapatite has not been shown to elicit an immune response, primary rejection is cell-mediated related to the major histocompatibility complex (MHC) incompatibility, Rapid incorporation via creeping substitution, Slower incorporation due to need to remodel existing Haversion canals, 25% of massive grafts sustain insufficiency fractures, Technically challenging with quicker union and cell preservation, Examples include: free fibula strut graft (peroneal artery), free iliac crest (deep circumflex iliac arteries), distal radius used for scaphoid fx (1-2 intercompartmental superretinacular artery branch of radial artery), BMP preserved and therefore osteoinductive, Alumina ceramic bonds bind to bone in response to stress and strain, Many prepared as ceramics (heated to fuse into crystals), Examples include: tricalcium phosphate, Norian (Synthes), hydroxyapatitie (tradename Collagraft by Zimmer), MONTAGE, Examples include: OsteoSet (Wright medical), Calcium carbonate skeleton is converted to calcium phosphate via a thermoexchange process (Interpore), Examples include: Biocora (Inoteb, france), Contains: collagen, bone morphogenetic proteins, transforming growth factor-beta, residual calcium, Does NOT contain mesenchymal precursor cells, Bone graft transferred from one body site to another in the same patient, osteogenic, osteoinductive, and osteoconductive, cortical, cancellous, or corticocancellous, source of osteogenic mesenchymal precursor cells, iliac crest and vertebral body most common sites, variable number of cells depending on patient age, provides both cancellous and cortical graft, higher complication rate with anterior versus posterior harvesting, stem cell concentration with posterior harvesting, injury to lateral femoral cutaneous or cluneal nerves, the degree of osteoconduction available depends on the processing method (fresh, frozen, or freeze-dried) and type of graft (cortical or cancellous), cortical, cancellous, corticocancellous, and osteoarticular (tumor surgery), preserved with glycerol or dimethyl sulfoxide (DMSO), cryogenically preserved (few viable chondrocytes remain), tissue-matched (syngeneic) grafts decrease immunogenicity, debridement of soft tissue, wash with ethanol (remove live cells), gamma irradiation (sterilization), dose-dependent higher doses of irradiation kills bacteria and viruses but may impair biomechanical properties, cleansing and processing removes cells and decreases the immune response improving incorporation, rarely used due to disease transmission and immune response of recipient, reduces immunogenicity while maintaining osteoconductive properties, two years for fresh frozen stored at -20 degrees C, five years for fresh frozen stored at -70 degrees C, removes the minerals and leaves the collagenous and noncollagenous structure and proteins, interproduct and interlot variability is common, Various compositions available (see summary above), Level I evidence shows that calcium-phosphate bone substitutes allow for bone defect filling, early rehabilitation, and prevention of articular subsidence in distal radius and tibial plateau fractures, stimulates undifferentiated perivascular mesenchymal cells to differentiate into osteoblasts through, Platelet rich plasma (PRP) (like other BMPs) solely osteoinductive, Provides large volume of bone graft from intramedullary source, femoral shaft fracture due to eccentric reaming, Differentiates from mesenchymal precursor cells, Stimulation of osteoblast and osteoclast function, risk of hepatitis B disease transmission in musculoskeletal fresh-frozen allograft transplantation is 1 in 63,000, risk of hepatitis C disease transmission in musculoskeletal fresh-frozen allograft transplantation is 1 in 100,000, risk of transmission of HIV in fresh-frozen allograft bone is 1 in 1,000,000 to 1,670,000, allografts are tested for HIV, HBV, HCV, HTLV-1, and syphilis, calcium sulfate bone graft substitute associated with increased serous wound drainage.
