Fecal impaction detection on a bone scan.
and posterior spot views of pelvis were obtained, which revealed the same finding (fig. 1). Horizontal images of computed tomography (CT) (fig. 2) showed a mass in the retrovesical region consistent with fecal impaction in rectum (posterior to the bladder). The zone of absent radiotracer activity in posterior projection images of the pelvis was attributed to attenuation of gamma rays by impacte...
متن کاملMechanical considerations in impaction bone grafting.
In impaction grafting of contained bone defects after revision joint arthroplasty the graft behaves as a friable aggregate and its resistance to complex forces depends on grading, normal load and compaction. Bone mills in current use produce a distribution of particle sizes more uniform than is desirable for maximising resistance to shear stresses. We have performed experiments in vitro using m...
متن کاملEsophageal large fish bone (sea bream jawbone) impaction successfully managed with endoscopy and safely excreted through the intestinal tract.
A 68-year-old man consulted our hospital because of back pain. A chest computed tomography (CT) demonstrated a high-density foreign body in the esophageal wall. There was no evidence of pneumomediastinum. Endoscopic examination demonstrated a large fish bone that was stuck in the esophageal wall. It was dislodged and moved into the stomach. The bone was excreted through the intestinal tract on ...
متن کاملImpaction grafting of the acetabulum with ceramic bone graft substitute
BACKGROUND AND PURPOSE Loss of bone stock remains a challenge in revision hip surgery. Grafting with allograft is well established, but there are problems with availability, cost, infection, antigenicity, reproducibility, and stability of the created construct. BoneSave is a biphasic porous ceramic consisting of sintered 80% tricalcium phosphate and 20% hydroxyapatite. In vitro and in vivo stud...
متن کاملImpaction bone-grafting in revision joint replacement surgery.
The standard graft material for impaction bone-grafting is fresh-frozen femoral head allograft morselized to a particle size as large as is practical to ensure stability and allow new bone formation. The graft must be sufficiently compacted to provide immediate mechanical stability; this requires containment of the graft and substantial impaction energy. Diaphyseal bone fracture and excessive i...
