Filter by:The purpose of the study is to investigate the efficacy of sleep medicine in the recovery of orthopaedic shoulder arthroplasty patients. The investigators hypothesize that a multimodal sleep pathway including non-pharmacological sleep hygiene interventions and the use of zolpidem can improve patient sleep, pain control, and subsequent recovery after undergoing total shoulder arthroplasty.
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 purpose of this study is to assess the early outcomes following Reverse Shoulder Arthroplasty (RSA) in patients sixty years or younger for the purpose of characterizing these patients, evaluating their clinical outcomes and radiographic appearance.The investigators would like to know how quickly they are healing and returning to their baseline activities of daily living and ability to work. This will help when counseling patients prior to surgery as it will give us a better defined and study supported understanding of the post-operative recovery timeline in the younger population.
Total shoulder replacement is associated with considerable postoperative pain. A common method to treat and prevent this post operative pain is to place a catheter in the neck and leave it in place for up to 48 hours. The catheter delivers a medication called ropivacaine directly to a major nerve near your shoulder. It is very effective at stopping pain. In addition to preventing pain, it also prevents movement of the arm because it blocks the nerve completely. A newer method of treating post operative pain uses only a series of small injections into the joint, skin, and muscles of the shoulder near the end of the surgery. This medication, liposomal bupivacaine (Exparel), potentially provides analgesia for greater than 48 hrs but does not require a catheter to remain in place and does not prevent patients from moving their arm after surgery because it only blocks the pain portion of the nerve. Both methods also frequently include the addition of oral and injected pain medicines like narcotics to effectively control the pain. Ropivacaine and Exparel both work well for postoperative pain after total shoulder replacement. It is not known, however, if one method is superior in its ability to treat/prevent pain or which method may have fewer side effects. The purpose of this study is to randomly assign patients to receive either a catheter with ropivicaine or Exparel injections to help determine if one method is superior in pain relief and if either method has fewer side effects.
Continuous interscalene brachial plexus block consists of inserting a catheter directly within the brachial plexus in the interscalene groove, between the middle and anterior scalene muscles, which is then infused with local anesthetic. This technique provides potent and site-specific analgesia for several days after major shoulder surgery, along with increased shoulder range of motion. A major side-effect of this procedure is the paralysis of the ipsilateral diaphragm, which is the main muscle of the respiration. This paralysis occurs at a rate of 90 to 100%, and is due to the spread of the local anesthetic towards the phrenic nerve, lying anteriorly to the plexus, between the sternocleidomastoid and anterior scalene muscles. Therefore, many patients suffering from respiratory syndromes, such as chronic obstructive pulmonary disease, will not have a continuous interscalene brachial plexus block, thus forfeiting some, or all, of the aforementioned benefits associated regional anesthesia. It is conventionally taught to place the needle tip between the nerve roots of the brachial plexus to obtain an effective block (intra-plexic injection). Recently, we have published a new technique of single-shot injection for interscalene brachial plexus block where the needle tip was positioned at a distance of 4 mm of the lateral part of the brachial plexus (extra-plexic injection) and resulted in a reduction rate of 70% of hemidiaphragmatic paresis and a preservation of spirometric values, while providing similar analgesia, when compared to a conventional injection. Contrary to single-shot injections where high volume and high concentration of local anesthetics are injected (eg, ropivacaine 0.5%, 20 mLs), continuous blocks required low volume and low concentration (eg, ropivacaine 0.1-2%, 2-6 mLs/h) and therefore the aforementioned concept of extra-plexic technique might not be suitable. Recently, new catheter-over-the needle (Contiplex® C; B. Braun Melsungen AG, Germany) have been released on the market and allows the physician to place the catheter tip exactly where he desires, contrary to the previous generations where the catheters were inserted blindly, despite the use of ultrasound. The first objective of that randomised controlled trial is to demonstrate that an extra-plexus catheter placement produces less respiratory complications than an intra-plexus catheter placement. The second objective is to confirm that both techniques provide similar analgesia.
The purpose of our study is to evaluate the effect of tramadol as an adjunct to ropivacaine local anesthetic solution in interscalene brachial plexus block for shoulder surgery.
