Filter by:The primary objective of this study is to examine whether there is a difference in the level of resting pain following total hip arthroplasty with an anterior approach with use of a psoas compartment block versus a local periarticular anesthetic infiltration
The purpose of this study was to develop a radiological method to measure stem anteversion and to determine its validity and reliability.
The purpose of this study is to describe and to compare the motion analysis parameters, i.e. motion and stability of proximal interphalangeal joints, which were treated with a CapFlex-PIP© implant or silicone implant and to generate basic knowledge about motion analysis of untreated healthy hands.
Purpose: Compare continuous adductor canal block (CACB) to Combined Spinal Epidural (CSE) for total knee arthroplasty in terms of mobility, post-operative pain, and analgesic use. Hypothesis: CACB will provide better mobility than CSE post operatively.
The goal of this retrospective chart review is to evaluate if the implementation of lumbar plexus block placement for postoperative pain and administration of multimodal oral analgesia have improved conditions in the postoperative period for patients undergoing total hip arthroplasty when compared to the placement of epidurals for postoperative pain management.
Short and long term outcomes of total knee arthroplasty patients surgically exposed with patellar eversion are compared to those patients exposed by laterally retracting the patella. It was hypothesized that there would be no difference.
The pupillary pain-meter AlgiScan ® with integrated nociceptive stimulator is a portable, battery-operated device which automatically measures, by means of an infrared camera, pupil diameter. This is measured in response to noxious stimulation produced by a tetanus at a frequency of 100 Hz for 5 seconds. Its intensity varies from 10 to 60 mA. The recording is performed for a period of 13 seconds (3 seconds prior to stimulation, stimulation for 5 seconds, 5 seconds after the stimulation). An interval of 3 minutes is allowed between the two measurements (right and left), which is significantly higher than the time necessary to return to normal (about 20seconds). The pupillary pain index (PPI) ranges from 0 to 10 and is a composite measure of the pupillary diameter reflex to the tetanus stimuli delivered by the AlgiScan device. Smaller scores indicate increased analgesia. The main objective of this study is to determine whether PPI index variation can determine a prognostic threshold of analgesic efficacy of unilateral lower limb sensory nerve block before incision. The measurements are performed after bilateral nociceptive stimulation (blocked side versus non-blocked side) in patients under general anesthesia for major knee surgery.
This study wish to show if the preoperative level of pain, function or activity for hip and knee arthroplasty patients has any predictive value of the time it takes to fulfill the well-defined discharge criteria.
The purpose of this study is to examine the efficacy of a dilute betadine solution in reducing infectious complications in revision total knee arthroplasty. The investigators will enroll patients who are scheduled to undergo a revision total knee arthroplasty. Patients will be randomized into two groups. The treatment group will receive a dilute betadine lavage prior to surgical closure for 3 minutes followed by 2000ml of sterile saline irrigation and the control group will receive the 2000ml sterile saline lavage alone.
Subjects will be consented and then determined randomly whether they will receive antibiotics prior to their surgery or during their surgery. Each patient will have cultures taken before and during their surgery from the infected hip or knee. Results will be compared after completion of the study.
