6 Clinical Trials for Various Conditions
The objective of the study is to evaluate the efficacy of preoperative treatment with a novel, wireless, low-level microcurrent-generating antimicrobial device (brand name: JumpStart) in preventing the spread of Propionibacterium acnes in patients receiving open or arthroscopic shoulder surgery.
The purpose of this study is to compare range of motion between a structured home exercise program to supervised physiotherapy post-operatively after Reverse Total Shoulder Replacement is performed for rotator cuff tear arthropathy/massive cuff tear through a single-center, assessor-blinded, randomized clinical trial.
Deep periprosthetic infection following total joint arthroplasty is a major complication. Although it only occurs in a small percentage of patients (\~1%), it results in substantial morbidity and a decline in functional outcome. A two stage revision and exchange is commonly required in order to clear the infection and provide the best opportunity for prosthetic replantation. Following removal of the infected components, a minimum course of six weeks of parenteral antibiotics is given and resolution of the infection confirmed through the ESR, CRP, and repeated aspiration of the joint. In most instances a temporary spacer of antibiotic-loaded cement is inserted at the first stage and removed at the second operation. Propionibacterium Acnes is a gram-positive, non-spore-forming, anaerobic bacillus found in lipid-rich areas, including hair follicles, sebaceous glands, and moist areas of the shoulder and axilla. Because of its low virulence, infections caused by P. acnes typically have a low-grade, indolent course, with shoulder pain often the only presenting symptoms after prosthetic replacement. P. acnes is particularly challenging to both diagnose and to eradicate, and is a substantial source of morbidity with shoulder arthroplasty. JumpStart™ is a wireless, advanced microcurrent generating, dressing used for the management of surgical incision sites. Microcell batteries made of silver and zinc, generate an electrical current when activated by conductive fluids, such as saline, hydrogel or wound exudate. These microcells create low voltage electrical fields to stimulate the surrounding area and to provide antimicrobial protection to assist with wound healing. JumpStart has demonstrated superior broad spectrum bactericidal activity of a wound dressing against antibiotic-resistant strains of wound isolates within 24 hours. The use of JumpStart as a prophylactic preoperative dressing to alter the skin flora and thereby decrease the risk of prosthetic infection has not been investigated to-date. Given the morbidity of a prosthetic infection, this would be a remarkably valuable intervention for any joint replacement procedure.
The objective is to compare two types of wound closure after total shoulder arthroplasty to determine which closure is faster, and subsequently if there are different outcomes between the two types of closures. The objective of this study is to compare two types of wound closure after total shoulder arthroplasty procedures. A single fellowship trained shoulder surgeon will perform all procedures. It is hypothesized that participants who undergo an 2-Octyl Cyanoacrylate (OCA) mesh closure will have a faster closure time, lower cost, non-inferior complication rate, and non-inferior satisfaction scores with respect postoperative follow up and scar appearance. Participants in the OCA mesh cohort will be compared to participants who have a closure with a running monocryl suture and dermabond. This investigation seeks to determine if OCA closure mesh closure is non-inferior to monocryl suture and dermabond in terms of operative time, cost, complications, and aesthetic appearance. If the hypothesis is confirmed, this study will suggest that a OCA mesh closure may be used for total shoulder arthroplasty surgeries as an alternative to current conventional closures and may provide a cost benefit.
Participants who choose to participate in this study, will either have their tendon repaired to tendon, so-called tenotomy repair, or tendon repaired to bone, so-called peel repair.
There is currently no consensus amongst orthopedic specialists on the best way to treat 3- and 4-part proximal humerus fractures. No surgery and surgery with a type of shoulder replacement called a reverse total shoulder arthroplasty are two options that many orthopedists use. This study is being performed to evaluate the differences in short- and long-term pain and functional outcomes between patients who are treated with these two different options.
