Surgery for Benign Biliary Tract Disease : An Analysis of 310 Cases from Smaller Hospitals
… the mean mortality, 2.4% among 25 reports of surgical mortality for gall stone disease found in the literature. The maximum number of cases came to surgery during the 6th decade. The highest relative incidence of elective biliary tract surgery was also during the 6th decade. The highest …

Development of a Descriptive Model of Flow Disruption Effect on Bypass Time in a Cardiovascular Operating Room
… interest is bypass time which is a critical surgical phase, the length of which has been linked to post-operation complications such as hospital-borne infections and readmission. By developing a model that predicts bypass time, the present research can determine the impact by types of flow …

Retrieval Analysis of Necropsy Total Hip Replacements: Considerations Beyond the Implant
… 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, …

Multimodality Somatostatin Analog For Fluorescence-Guided Surgery In Cancer
… are widely used during the pre- and postoperative stages, but intraoperative disease recognition relies on direct visual inspection and the hands of surgeons. The limited number of clinical tools for real-time intraoperative visual feedback restricts the ability to remove the complete …

Antibiotics and the Wasting Disease in Neonatally Thymectomized Rats
… with infections acquired in the immediate post-operative period, These results corroborate the conclusions of Azar (1964) relative to the efficacy of antibiotic administration in preventing the wasting disease, and also are in accord with the findings of Miller (1964) that germ free …

Factors Influencing Uptake of Risk-Reducing Salpingo-Oophorectomy By Brca1 and Brca2 Mutation Carriers
<p>Germline mutations in the <em>BRCA1</em> and <em>BRCA2</em> genes are associated with significantly increased risks for ovarian cancer. The National Comprehensive Cancer Network (NCCN) currently recommends that female BRCA mutation carriers undergo risk-reducing salpingo-oophorectomy (RRSO) …

Biomechanical Comparison of Lumbar Disc Replacements
<p>Surgical options for lumbar spinal disorders are rapidly expanding. One seemingly promising area is the lumbar disc replacement. Design specifications vary among the manufacturers based upon differing perceptions of ideal motion. Comparison studies are important in quantifying different features …

Total Knee Arthroplasty Wear Is Caused by Malrotation and Excessive Laxity
… which combines specially designed components and surgical processes to treat cartilage degeneration and alleviate pain in arthritic knees. However, this technique is limited by component design and surgical precision. Due to these limitations, knee arthroplasty components will eventually wear out, …

Determination of the Functional Relationship Between Lumbar Lordosis and Pelvic Tilt
<p>Americans are undergoing spinal fusion surgery (SFS) at an ever increasing rate; in 2008 over 400,000 Americans underwent SFS with a national cost of approximately $33.9 billion. During SFS it is difficult for the surgeon to properly align the spine’s s-shape, as viewed from the patient’s side. …

Kinematic Demands of Nucleus Arthroplasty Technology
… technologies have fostered growth in alternative surgical procedures to fusion surgery for treatment of early stages of degenerative disc disease. One application of immediate interest is that of nucleus arthroplasty (NA). Novel materials are being developed to better match the nonlinear …

Biomechanical Testing of Two-Level Cervical Disc Arthroplasty
<p>In vitro biomechanical studies comparing two-level cervical disc arthroplasty with two-level fusion were completed using an established cadaveric cervical spine model. Three conditions were tested: non-instrumented, instrumented with two-level fusion (C5-C6 and C6-C7), and instrumented with …

Iatrogenic Electrocautery Damage and Cellular-Based Corrosion of Total Joint Arthroplasty Biomaterials
<p><strong>Introduction.</strong> The number of patients undergoing a Primary Total Knee Arthroplasty (PTKA) has been increasing steadily each year. Of those PTKA patients, 20% report long-term pain and/or some functional deficit. Cobalt-Chromium-Molybdenum (CoCrMo) alloy is one of the most used …

Failure of Primary Total Knee Arthroplasty: Establishing a Baseline for Retrieval Analysis Using Well-Functioning Necropsy Specimens
<p><strong>Introduction</strong>. Total knee arthroplasty (TKA) is an effective treatment for end-stage osteoarthritis of the knee. While many patients have positive functional and pain outcomes following primary TKA, a subset of patients have suboptimal outcomes, such as unexplained pain or …
