Effects Of Playing Surface And Shoe Type Of Acl Tears In Soccer Players, Melissa Mansfield
Honors Theses
Anterior Cruciate Ligament injuries have become more common in athletes over the past decade which is believed to result from playing on more artificial turf surfaces. This study tested the playing surface theory by building upon a previous study conducted with Albany Medical Center which tested surface samples using an axial-torsion load frame located at Union College. The motion that causes most ACL noncontact injuries is replicated by the load frame which pushes and rotates a shoe against the playing surface and measures the torque it experiences. The foot position, normal load, degree of rotation and rate of rotation were …

Metastatic bone cancer often arises in the long bones of the body. Taking a patient specific approach by utilizing a customized implant is a superior method of treatment compared to today’s solutions, which often includes amputation. A titanium-alloy femur implant has been optimized by varying pore size, pore pattern, and porosity in order to maximize osseointegration. By maximizing osseointegration, the implant will remain firmly in place for a longer period of time because bone will grow throughout the implant, securing it. In addition, it is important for the bone to behave mechanically like bone. This requires the global elastic modulus …

Analysis Of Degenerative Cervical Spondylolisthesis And Corrective Orthopaedic Implants, Tyler Heck
Honors Theses
Back pain is often due to the degeneration of intervertebral discs, which can lead to a condition known as spondylolisthesis, whereby a vertebra slips out of position in the anteroposterior direction. There are numerous orthopaedic implants which are used by surgeons to correct this condition; however, there has been no conclusive research conducted in comparing the efficacies of these implants. In the cervical spine, this condition most commonly occurs over two levels. For the purposes of this study, an implant’s efficacy depends on its ability to return the slipped vertebra back into natural position immediately after surgery. To test these …
