Comprehensively understanding the mechanics of loads transmitted to the spine during scoliosis corrective surgery will improve surgical outcome and patient safety. A system consisting of wireless instrumented hooks and screws, and a wireless data acquisition system was developed to measure the loads and moments imposed during scoliosis surgery. From laboratory tests, the maximum error of posterior/anterior...
We studied birefringence as an indicator of collagen fiber orientation in the diaphysis of the equine third metacarpal bone. We had previously shown that tissue from the lateral cortex of this bone is stronger monotonically, but less fatigue resistant, than tissue from the medial and dorsal regions. To learn whether collagen fiber orientation might play a role in this regional specialization, we...
This work determined whether mineral dissolution due to prolonged testing or storage of bone specimens in normal saline would alter their elastic modulus. In one experiment, small pieces of equine third metacarpal bone were soaked in normal saline supplemented with varying amounts of CaCl 2 . Changing Ca ion concentrations in the bath were monitored and the equilibrium concentration was determined...
