Filter by:The purpose of this study is to evaluate preoperative objective measurements and operative objective measurements to determine if there is any effect to postoperative outcomes. Patients who were 18 years old or greater at the time of surgery were followed clinically and radiographically to determine best practice and optimal treatment and technique, risk and rate of complication, and postoperative outcomes.
The purpose of the study is to determine if pain management after total shoulder arthroplasty is more efficacious with ultrasound guided, continuous Interscalene block or with local tissue infiltration with liposomal bupivacaine. Traditionally, general anesthesia followed by narcotics has been the primary management of pain control. However, regional anesthesia in the form of an interscalene block (ISB), a perineural local anesthetic infusion, is commonly used and may more effectively control pain during and after shoulder arthroplasty, with fewer side effects than narcotics. Intraoperative benefits include better control of blood pressure and reduced need for general anesthesia and narcotics. Depending on the type of block (single shot vs. continuous) and the type of local anesthetic administered, pain relief may persist for 12-96 hours postoperatively. However, not all patients are candidates for peripheral nerve blocks. Pre-existing pulmonary disease, previous neck surgery, cervical arthritis, neurologic disorders and obesity may preclude ISB placement. As well, interscalene blocks are not completely benign procedures. Systemic complications include clinically significant intraoperative hypotension, pneumothorax, vascular injury, cardiac arrest, respiratory failure, seizure and death. Phrenic nerve paralysis is common, although transient. Peripheral nerve injuries related to mechanical injury, medication neurotoxicity, compression or ischemia are infrequent but may be devastating. The experience and number of blocks performed by the anesthesiologist in addition to adjunctive tools, such as ultrasound and/or nerve stimulators, impacts the success of the procedure. Continuous indwelling interscalene blocks (CISB) may provide substantial and longer pain relief, precluding the need for perioperative narcotics. Earlier discharge post procedure and better early range of motion are other purported benefits. However, premature catheter failure, catheter breakage, infection, over administration of medication and extended diaphragmatic paresis are concerns. In addition, there is a cost associated with these procedures. The anesthesiologist fee, catheter with or without elastomeric pump, local anesthetic, perioperative patient evaluation and treatment of any associated complications all must be considered. . The development of new, long acting local anesthetics, such as liposomal bupivacaine, is potentially important in the management of perioperative pain. Liposomal bupivacaine has been approved by the US Food and Drug Administration for local infiltration for pain relief after bunionectomy and hemorrhoidectomy. This preparation increases the duration of local anesthetic action by slow release from the liposome and delays the peak plasma concentration when compared to plain bupivacaine administration. Studies have shown it to be an effective tool for postoperative pain relief with opioid sparing effects and it has also been found to have an acceptable adverse effect profile.
The purpose of this study is to determine the efficacy of retrieving tissue samples via an x-ray guided needle that is inserted into the infected tissue in the shoulder. The procedure using the guided needle is called a synovial biopsy versus an open tissue biopsy, which is done at the time of surgery. By doing the synovial biopsy prior to a revision surgery, the investigators hope to avoid more invasive intervention if it is not needed. Some patients may appear to have an infection but once the biopsy is taken and the results are read, there may not be an infection and therefore no need for a revision surgery.
The purpose of this study is to determine which medication(s) should be included in the interscalene nerve block (an injection of local anesthetic [numbing medicine] near nerves in the shoulder) for patients undergoing total shoulder arthroplasty (shoulder replacement). The ideal nerve block would reduce pain after shoulder surgery without causing a great deal of muscle weakness.
The proposed study aims to objectively assess 2-year clinical and radiographic results for the rate of glenoid component loosening in total shoulder arthroplasty (TSA). This retrospective radiographic review will provide evidence for equivalence or superiority in curtailing loosening, a known complication in arthroplasty, when a hemostatic agent is utilized in conjunction with cement at the glenoid.
Total shoulder arthroplasty (shoulder replacement) can cause severe postoperative pain. Commonly, patients receive general anesthesia with interscalene block (injection of local anesthetic or numbing medicine near nerves in the shoulder) during surgery. As a result of the interscalene block, patients often experience sensory and motor blockade. The purpose of this study is to determine the effects of the interscalene block on the anterior deltoid muscle and hand grip strength after total shoulder arthroplasty.
