-
Chest radiograph of patient with osteosarcoma who died from pulmonary metastatic disease. Note the presence of a pneumothorax as well as radiodense (bone-forming) metastatic lesions.
-
Clinical appearance of a teenager who presented with osteosarcoma of the proximal humerus (same patient as in the following images). Note the impressive swelling throughout the deltoid region, as well as the disuse atrophy of the pectoral musculature.
-
Radiographic appearance (plain radiograph) of a proximal humeral osteosarcoma (same patient as previous image). Note the radiodense matrix of the intramedullary portion of the lesion, as well as the soft-tissue extension and aggressive periosteal reaction.
-
Intense radionuclide uptake of the proximal humerus is noted on a bone scan (same patient as previous 2 images).
-
A comparison bone scan of the involved shoulder (right image) with the uninvolved shoulder (left image) (same patient as previous 3 images).
-
Magnetic resonance image appearance (T1-weighted image) of osteosarcoma of the proximal humerus (same patient as previous 4 images). Note the dramatic tumor extension into the adjacent soft-tissue regions.
-
Core needle biopsy instruments commonly used for bony specimens. Craig needle set.
-
Close-up view of Craig needle biopsy instruments. Cutting cannula with T-handle attached (top) and sheath through which the cutting cannula passes (bottom).
-
Resected specimen of a proximal tibia osteosarcoma. The primary lesion was such that the knee joint was resected with the primary lesion. Note that the previous longitudinal biopsy tract was completely excised with the specimen.
-
Intraoperative consultation with the pathologist, in which the surgeon and pathologist view the microscopic appearance of the biopsy specimen.
-
Intraoperative consultation with the pathologist. A frozen section of the biopsy specimen is being performed.
-

-
Clinical photograph taken at the conclusion of a Van Ness rotationplasty procedure (same patient as previous image). Note that the new "knee" of the operative side (left side) is purposely reconstructed distal to the normal right knee. This is in anticipation of the future growth potential of the unoperated limb.
