Filter by:1. Interscalene continuous catheter is a very effective way of controlling pain in total shoulder arthroplasty. To ensure proper placement, nerve stimulating catheter is quite often used. 2. Ultrasound can help proper placement of catheter without relying on nerve stimulation. 3. The plan of the study is to compare two techniques head to head to see if they are equally effective or one is better than others.
The purpose of this study is to investigate the cardiovascular changes during early postoperative mobilization of hip arthroplasty patients.
The main purpose of this prospective randomized controlled trial is to compare the concentrations of metal ions in the blood and urine of patients receiving implants that are identical except for the acetabular component: one is a monoblock and all cobalt chrome, and the other is modular with a titanium acetabular shell with a polyethylene insert.
The purpose of this study is to determine whether a higher threshold for transfusion with red blood cells improves the postoperative ambulation.
Post-Approval Study (PMA CoA) in Order to Obtain Additional Long Term Safety and Effectiveness Data [PMA P020016]
Basic Protocol 1. Identify participant(s) 2. Request patient participation/Acquire Consent 3. Register patient at www.stabilityplus.net through the LOGIN tab - Patient ID (Name/Initials/SSN or any combination thereof) - Gender - Age - Surgical Procedure - Date of Surgery - Select Basic Exercise Program that corresponds with Surgical Procedure 4. Perform Initial Assessment using Basic Exercises for the Surgical Procedure 5. Enter Assessment Data at www.stabilityplus.net (through the LOGIN tab/Portal) 6. Within portal, modify Basic Exercise Program to create customized Stability Plus prescription for the patient 7. Monitor patient progress through Stability Plus portal.
Evaluate the efficacy, safety and tolerability of a single intraoperative dose of 4975 in patients undergoing total hip replacement
Ten patients 70 years and older having elective total hip/knee replacement surgery will be recruited to receive a continuous IV infusion of naloxone and oral tramacet for analgesia. Postoperative analgesia, satisfaction, side effects, need for rescure analgesia, and length of stay.
The purpose of this study is to describe the 3D joint biomechanics of the lower extremities of patients having had a total hip replacement or hip resurfacing surgery as compared to a healthy age and weight matched control group during level walking, stair ascent and descent, and entering and exiting the front seat of a car.
The aims of the study are to determine whether pamidronate applied locally causes diminished periprosthetic bone loss and decreased rate of bone turnover compared to patients receiving placebo after cemented total hip arthroplasty (THA). The study design will be prospective, randomized, and blind. Periprosthetic bone mineral density (BMD) will be measured with dual energy X-ray absorptiometry (DXA) at the total periprosthetic area as well as at seven Gruen zones or regions of interest. DXA scans will be performed at one week (baseline), three months, and six months postoperatively. Mean values of biochemical markers of bone turnover, BMD, and baseline-normalized BMD values will be compared between the bisphosphonate and placebo groups at each time point. For all temporal measurements including bone markers, BMD and normalized BMD, mean values will be compared across each time point within a given group.
