Abstract
This practical talk covers a range of bone specimens handled and reported at Middlemore Hospital, the site of the New Zealand Bone and Soft Tissue Tumour Registry. A variety of techniques and approaches for the gross handling of the specimens and equipment is discussed. This includes dealing with a large limb amputation specimen, to a limb salvage specimen comprising a wide excision of bone and soft tissues, to smaller excision specimens, curettings of bony tissue and finally undecalcified bone specimens for quantitative histomorphometry. The use of band saws, desk top skill saws, and hand saws is illustrated. Principles of decalcifying bone are also discussed. Cases that have been selected to demonstrate this range of techniques include synovial chondrosarcoma, pleomorphic undifferentiated sarcoma, conventional osteosarcoma, post-radiation osteosarcoma, degenerative joint disease, osteomyelitis, and hypophosphatasia concurrent with renal bone disease.
