Retrieval Analysis Of Necropsy Total Hip Replacements: Considerations Beyond The Implant, Julie Alyse Lowell Dec 2017

Retrieval Analysis Of Necropsy Total Hip Replacements: Considerations Beyond The Implant, Julie Alyse Lowell

Theses and Dissertations (ETD)

Introduction. Total hip arthroplasty (THA) surgery is one of the most commonly performed and successful orthopedic procedures in the United States. More than 300,000 primary THAs and 40,000 revision THAs performed in the United States every year. While the need for revision surgeries can stem from a variety of causes, there have been, to the author’s knowledge, no studies attempting to correlate the concentrations of certain inflammatory cytokines to metal ion concentrations found in the tissue surrounding the implant, amount of polyethylene wear, or strength of the interface of the modular taper. The purpose of this study was to begin …


A Novel Distractive And Mobility-Enabling Lumbar Spinal Orthosis For Treating Mechanical Low Back Pain, Daniel Clay Hillyard May 2017

A Novel Distractive And Mobility-Enabling Lumbar Spinal Orthosis For Treating Mechanical Low Back Pain, Daniel Clay Hillyard

Theses and Dissertations (ETD)

Introduction: Lumbar spinal orthoses (LSOs) are often used as non-surgical treatment and serve to support the spine and alleviate low back pain. More recently, dynamic orthoses claiming to decompress the spine have been introduced. Currently, there is an unserved population of people that suffer from mechanical low back pain (LBP) conditions, such as degenerative disc disease or lumbar foraminal stenosis, that would benefit from spinal decompression and mobility. A previously-developed prototype of dynamic mobility orthosis (DMO1) was designed that provided a distractive load across the lumbar spine but required higher sagittal bending moments and was unable to maintain spinal off-loading …


Quantifying Joint Coordination Variability In Anterior Cruciate Ligament-Reconstructed Individuals During Walking, Kylie Davis May 2017

Quantifying Joint Coordination Variability In Anterior Cruciate Ligament-Reconstructed Individuals During Walking, Kylie Davis

Theses and Dissertations (ETD)

The knee is the second most common joint to sustain injury. An estimated 200,000 anterior cruciate ligament (ACL) ruptures occur each year in the United States alone, and about 100,000 ACL reconstruction (ACLR) surgeries are performed annually. There is a significant risk of developing osteoarthritis of the knee after incurring an ACL injury, and the incidence of ipsilateral or contralateral injury is six times greater in individuals who have a surgically repaired ACL. Past studies have analyzed kinetic and kinematic characteristics of individual lower extremity joints to reveal differences between subjects with and without ACLR. Despite reports of altered kinematic …


Design, Validation, And Clinical Testing Of A Novel Fastening Device For A Scoliosis Brace, Cody Keith Bateman May 2017

Design, Validation, And Clinical Testing Of A Novel Fastening Device For A Scoliosis Brace, Cody Keith Bateman

Theses and Dissertations (ETD)

Each year, thirty thousand children in the US were put into a scoliosis brace. The primary function of scoliosis braces was to reduce and prevent progression of the spinal deformity as the patient grew by application of corrective forces to the spine. Straps, often made of Velcro, were attached to the back of the brace that applied forces to the spine when the straps were tightened. Braces were prescribed to be worn up to 23 hours a day. Studies have concluded that discomfort increased with increasing strap tension and pad pressure. They have also shown an increase in strap tension …
