Active clinical trials for "Joint Diseases"

The primary objectives of this clinical study include: Assess the rate of dislocation and fracture of THA using the new (the 4th generation) ceramic implants. Evaluate the survival rate of THA using the new alumina-zirconia (the 4th generation) composite ceramic bearing. Investigate the performance of the 4th generation ceramic implants mostly in patients younger than 50 years. Compare the preoperative and postoperative scores of Harris Hip Score, UCLA Activity Score and WOMAC.

This investigation describes a novel complex of structural degradation proteins that is associated with pain in individuals with meniscal pathology undergoing arthroscopic partial meniscectomy. The presence of the complex in the synovial fluid of the knee is sensitive and specific for the painful state compared with similar aged controls. The absence of the complex in asymptomatic controls makes it a useful biomarker for the disease state.

The overall purpose of this study is to develop an improved gait analysis system for the real time acquisition, calculation and interpretation of joint kinematic and kinetic information using linked segment body model animation to display and visually depict deviations from normal motion and joint function. Patients referred to the laboratory for clinical gait analysis are invited to participate in the project. If interested, subjects are informed by a study investigator of the study goals, procedures, risks and any benefits. A study investigator is responsible for obtaining informed consent. Data from normal subjects are used to establish a normative database. Data from other subjects contributes to the relevant databases of different disorders.

The aim of the present investigation was to perform the content and construct validation of the diagnostic criteria for TMD (DC/TMD) Axis I, for children 7 to 11 years old. A Delphi process was used to perfom the content validity of the DC/TMD Axis I. 189 7-11 years old children were assessed with the adapted instrument. Confirmatory factor analysis (CFA) was used to investigate construct validity of the DC/TMD for children. A baseline one-factor model was compared against a two-factor (Model 2) and a seven-factor (Model 3) models based on the original DC/TMD. Root-mean-squared error of approximation (RMSEA), comparative fit index (CFI), chi-square, change in chi-square and Cronbach's Alpha were used to analyze the data. All analysis were performed in STATA© version 13.0.

The aim of the study was to evaluate any relation between elongated styloid process (ESP) and type of Temporomandibular Joint Disorders (TMD).

This study is to determine the relevancy of clinical scales for outcome measures as compared to flexion angle and other gait measures. Clinical outcomes measures in the form of the Knee Society Score and the WOMAC Score will be obtained from patients. Gait data will also be obtained from total knee replacement (TKR) patients at pre-operative and post-operative times. Gait data will be measured on unaffected normal controls as a second baseline. The hypothesis is that the subjects clinical outcome measures do not accurately reflect gait dependent outcomes amd functional performance of the total knee replacement.

It was proposed in this study to evaluate the prevalence of TMD signs and symptoms in State University of West of Parana's dental students with natural dentition, in patients with removable partial dentures and double complete dentures.

This study provides a mechanism for evaluating patients for possible participation in NIDCR clinical research studies. NIDCR studies involve three major areas-pain, neurosensory mechanisms, and pain-relieving drugs-all of which have specific requirements and patient characteristics. No treatment is offered under this protocol; it is intended to facilitate patient recruitment into NIDCR studies. Patients with unusual or unknown conditions that have or have not been diagnosed may be eligible for this screening study. Specific medical criteria for enrollment vary with the particular protocol for which the individual is being screened. Medical and dental histories will be obtained and participants will have a dental examination. Diagnostic procedures will be done in accord with standard medical and dental practice and may include X-rays, blood tests, and routine urinalysis, as appropriate. Participants found eligible for an active study may enroll in that study. Those who are not eligible for a current study may be re-evaluated for future studies within a year if they wish. After 1 year, participants for whom no appropriate studies are identified will be referred back to their primary doctor or referring physician or dentist.

vacuum formed retainer act as bite raiser that increase vertical dimension which may affect Tempromandibular joint and aim of this study is to perform clinical and radiographic evaluation of different thickness of vacuum formed retainer (Essix retainer) during retention phase after orthodontic treatment

Reverse total shoulder arthroplasty has been widely used in the treatment of rotator cuff arthropathy. Follow-up has historically focused on the glenoid component because of problems with fixation and scapular notching leading to functional failure. Fixation of the humeral component has evolved from cemented to mostly uncemented with diaphyseal of metaphyseal press-fit stems. Bony changes around the stem reflect the bone-implant interface; research to evaluate and interpret these changes is insufficient at this moment. Since several patients have shown cortical thinning of the proximal lateral humeral cortex during follow-up, further research is recommended to evaluate the cause and clinical impact of these radiographic changes. The goal of this study is to collect long-term radiographic and clinical data in order to facilitate the identification of risk factors.
