Factors Affecting The Outcomes In Bilateral Total Knee Arthroplasty: A Case Report, Laura K. Parry

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The purpose of this case study was to determine the effects of femoral nerve block use during total knee arthroplasty on the return of quadriceps activation and functional outcomes in a single patient. This case study focused on an individual case consisting of simultaneous bilateral knee replacement. The individual received a femoral nerve block in one knee and traditional anesthesia in the other. We considered the improvement in functional outcomes following surgery. It was expected that the femoral nerve block will delay the activation of the quadriceps muscle and the return of functional measures. However, the femoral nerve block will …

A Comparison Of Upper Extremity Function Between Female Breast Cancer Survivors And Healthy Controls: Typical Self-Report Of Function, Motion, Strength, And Muscular Endurance, Mary Insana Fisher

Physical Therapy Faculty Publications

Many women who have experienced breast cancer (BC) report continued impairments in upper extremity (UE) function beyond the time required for normal healing after surgical treatment. Most research supporting this has not made comparisons between survivors of breast cancer (BCS) to a sample of healthy women. This lack of comparison to a healthy cohort prevents an understanding of whether continued deficits in UE function are due to normal aging or the BC treatment.

The purpose of this research was to compare quality of life (QOL) and UE function among long term breast cancer survivors and similar aged women without cancer. …

Antibiotic-Like Actions Of Vitamin D, Franklin D. Shuler Md, Phd, Josh Hendrix, Adam Short, Sammy Hodroge

Orthopaedics

Vitamin D is a secosteroid hormone that has expanding importance for a healthy lifestyle and disease prevention. A multitude of studies have highlighted that vitamin D acts not only in bone and calcium homeostasis but is critically important for human immunity. The discovery that the storage form of vitamin D (25-hydroxyvitamin D3) can be locally converted to the active form (1,25-hydroxyvitamin D3) in immune cells, epithelial cells and numerous other non-renal tissues highlights the importance of maintaining sufficient stores. When responding to a specific external stimulus, like bacterial invasion, intracrine synthesis of active vitamin D has the ability to regulate …

Effect Of Doping On Β-Tricalcium Phosphate Bioresorbable Bulk Material And Thin Film Coatings, Suhaila Abdalla

Dissertations

Magnesium has emerged as a revolutionary biodegradable metal for use as an orthopedic material, it has several advantages over the permanent metallic materials currently in use, including eliminating the effects of stress shielding, improving biocompatibility and degradation properties, thus removing the requirement of a second surgery for implant removal. Due to the rapid degradation of magnesium, it is necessary to control the corrosion rates of the materials to match the rates of bone healing. This dissertation reports on the effect of doping on the properties of β-tricalcium phosphate (β-TCP). It also reports on its application as a thin film coating …

Infections In Anterior Cruciate Ligament Reconstruction, C. Stucken, D.N. Garras, J.L. Shaner, Steven B. Cohen

Rothman Institute Papers

Context: Anterior cruciate ligament (ACL) reconstruction is a safe, common, and effective method of restoring stability to the knee after injury, but evolving techniques of reconstruction carry inherent risk. Infection after ACL reconstruction, while rare, carries a high morbidity potentially resulting in poor clinical outcome.

Evidence Acquisition: Data were obtained from previously published peer-reviewed literature through a search of the entire PubMed database (up to December 2012) as well as from textbook chapters.

Results: Treatment with culture-specific antibiotics and debridement with graft retention is generally more effective than graft removal, but with persistent infection consideration should be given to graft …

The Effects Of A Semi-Rigid Ankle Brace On A Simulated Isolated Subtalar Joint Instability, Julie Choisne, Matthew C. Hoch, Sebastian Bawab, Ian Alexander, Stacie I. Ringleb

Mechanical & Aerospace Engineering Faculty Publications

Subtalar joint instability is hypothesized to occur after injuries to the calcaneofibular ligament (CFL) in isolation or in combination with the cervical and the talocalcaneal interosseous ligaments. A common treatment for hindfoot instability is the application of an ankle brace. However, the ability of an ankle brace to promote subtalar joint stability is not well established. We assessed the kinematics of the subtalar joint, ankle, and hindfoot in the presence of isolated subtalar instability, investigated the effect of bracing in a CFL deficient foot and with a total rupture of the intrinsic ligaments, and evaluated how maximum inversion range of …
