50 Clinical Trials for Various Conditions
This study, titled "Mixed-Methods Evaluation of Short-, Medium-, and Long-Term Outcomes Following Hip Treatment," aims to assess the long-term effectiveness of treatments for pediatric hip conditions, including hip dysplasia, Legg-Calve-Perthes disease, SCFE, and avascular necrosis.
The goal of this observational study is to compare postoperative results between patients who had total hip arthroplasty (THA) with and without the use of a computer navigation program. The main questions this study aims to answer are: * Can using computer navigation produce better THA implant placement? * Can using computer navigation make surgery more efficient? Participant data collected include their postoperative x-rays and total operative time.

This study evaluates the feasibility and utility of contrast-enhanced ultrasound to provide real-time assessment of blood flow to the femoral head in infants undergoing surgical reduction for developmental dysplasia of the hip.
Two-year (2 year) information regarding the performance of the commercially available Actis™ Total Hip System in order to obtain and evaluate the clinical outcomes on a series of cementless primary total hip arthroplasty (THA) and hemi-hip arthroplasty procedures using clinical, radiographic and device and procedure related adverse event assessments.
The purpose of this study is to determine how effect lacosamide is in reducing the amount of pain medication needed following a total hip arthroplasty. The study team hypothesizes that a single dose of lacosamide will reduce the amount of pain medication required after surgery. The study team plans to evaluate the amount of pain medication needed and quality of pain control during a subject's hospital stay and at their three month follow-up visit following their surgery.
This study is intended to gather medium (5- to 7-years) and long-term (minimum 8- to 10-years) information regarding the performance and safety of the commercially available 36mm CERAMAX® Ceramic on Ceramic (COC) Total Hip System from a cohort of study subjects that were previously enrolled in the IDE study. (COC = 36mm ceramic acetabular bearing insert component that articulates with a ceramic femoral head in the COC total hip replacement system)
Hip replacement is a common surgical procedure performed to relieve the pain and disability. In general, the surgery consists of replacing the diseased or damaged joint surfaces of the hip with metal and plastic components shaped to allow continued motion of the hip. Surgeons may perform this operation in several different ways. The purpose of this study is to compare two different methods of performing total hip replacement. The investigators hypothesize that subjects treated with the anterior approached may show improved function during the early postoperative period, but that no differences in pain or function will be present after the first postoperative year. In this study, patients that have elected to have hip replacement and consented to participate in the study will be randomized to have his or her hip replaced using one of two surgical techniques. Subjects will be randomized to be implanted using either an anterior or posterior approach. With the anterior approach, the study surgeon will use an incision that is on the front of the hip, and with the posterior approach, the incision will be more on the backside of your hip. The study surgeon has done more than 300 total hip replacements with both of these techniques. A baseline assessment will be conducted before hip replacement surgery that includes x-rays, functional tasks like getting up from a chair and stepping down a step, and three questionnaires about the hip, the subject's general health, and how well the subject is able to function. Also, subjects will be required to return to the clinic at several time points after surgery for follow-up visits. Follow-up visits will include hip assessments and questionnaires, as well as follow-up hip x-rays. The follow-up visits will be 6 weeks, 3 months, 1 year, 2 years, 5 years, 7 years, and 10 years after hip replacement surgery. These follow-up visits are part of the study surgeon's normal routine for hip replacement patients, and are not extra visits as a part of this study.
This study is intended to gather medium (0-5 years) and long-term (6-10 years) information regarding the performance and safety of the commercially available Ceramax™ Ceramic on Ceramic Total Hip System. This is a two-phased study consisting of a clinical follow-up phase and a clinical outcomes phase. In Phase One (0-5 years), diagnostic, demographic and operative information will be gathered for each subject enrolled in this study. In addition, Harris Hip Evaluations, subjective evaluations and radiographs will be completed annually. In Phase Two (6 - 10 years), a subjective outcomes questionnaire and a SF-12 Health Survey will be mailed to subjects annually.
