Active clinical trials for "Rotator Cuff Injuries"

Arthroscopic repair has become the preferable surgical technique to treat rotator cuff tears in the last decade. Many researches demonstrate equal and even superior outcome with this surgical technique, while others show opposite results. The aim of this study is to estimate the anatomic and functional results of the arthroscopic repair among the patients of the orthopedic department at the Soroka University Medical Center, in order to check the investigators hypothesis that indeed - the arthroscopic repair of the rotator cuff is the better surgical technique. Methods: study population - 80 patients who had had an arthroscopic repair of the rotator cuff between the years 2005-2008 at the SUMC. Inclusion criteria: age over 18 years. arthroscopic rotator cuff repair. date of operation not before 2005. Study design: Data base Collection. Inviting the patients for physical examination + ultrasound examination of the operated shoulder + filling out questionnaires (SF36, CONSTANT SCORE) Statistical analysis Publication

Full-thickness rotator cuff tears (FTRCT), defined as "through-and-through" tears of one of the shoulder tendons, affect up to 32% of the population (mostly individuals older than 50 years) and are one of the most painful and debilitating shoulder diagnoses. One of the primary challenges for clinical decision-making is the poor association between the presence of FTRCT (detected by medical imaging) and pain, as studies have shown that 2/3 of people with FTRCT are asymptomatic. This challenges the notion that FTRCT causes pain, and highlights the fact that symptoms may be explained by other variables. A better understanding of the factors leading to the development of pain in people with FTRCT would optimize clinical care (including prevention). The objective of this study is to identify variables associated with pain in people with FTRCT by 1) comparing people with FTRCT with (Symptomatic Group; n=40) and without pain (Asymptomatic Group; n=40); 2) comparing people who initially have pain-free FTRCT (Asymptomatic Group) who develop pain over a 2-year period to those who do not develop pain; and 3) comparing people who initially have painful FTRCT (Symptomatic Group) who become pain-free over a 2-year period to those who remain symptomatic. All participants will undergo an ultrasound examination to confirm the presence of FTRCT, and information on a number of variables (sociodemographic, anatomical, genetic, psychosocial, pain sensitivity, neuromuscular, biomechanical) will be collected. All participants will then be followed for 2 years before being revaluated for pain. Variables will be analysed to determine those associated with pain. As it is crucial to improve our understanding of the mechanisms leading to pain, this project has the potential to impact the musculoskeletal health of Canadians. By considering multiple variables associated with FTRCT, its results could lead to the development of tangible solutions to optimize prevention and recovery.

This study will try to develop and determine objective and validated criteria for our athletes to safely return to sports after labral repair.

Chronic ankle pain is a common clinical problem with a wide differential diagnosis. Soft-tissue and osseous impingement syndromes are now increasingly recognized as a significant cause of chronic ankle pain. Ankle impingement syndromes are defined as pathologic conditions resulting in chronic, painful restriction to movement at the tibiotalar articulation secondary to soft-tissue or osseous abnormalities. Ankle impingement is classified according to its anatomic relationship to the tibiotalar joint as anterolateral, anterior, anteromedial, posteromedial, or posterior impingement.

The purpose of this project is to extract effusions and damaged tendons during tendon repair therapy in patients with tendon tears. Then, we would analyze tendon-related transcription factors from histology and cytology, and compare changes in tendon with ultrasound images. Helps to understand the mechanism of tendon lesions.

There are two purpose of this study, first is to find whether arthroscopic rotator cuff repair is changing the appearance of supraspinatus muscle atrophy in each and every patient. Second, is to find how much approximate change one can expect depending on age and tendon retraction

The proposed study will be a multi-centre, prospective, observational cohort to determine if psychological well-being has an impact on the outcome of surgical repair for rotator cuff tears.

Identification of biomarkers that can predict the outcome of the surgical treatment (i.e. the rate of re-rupture) of tears in the rotator cuff tendon.

Previous studies used spatial frequency analysis of tendon ultrasound images and considered that the parameters can reflect the micro-structure of the tendon. In this study, we try to recruit and analysis the rotator cuff tendon in healthy adults with different ages and different equipment to explore the the normal range and differences of spatial frequency parameters. The hypotheses of this study are (1) the young and the elderly would have significantly different spatial frequency value; and (2) there would be significant different results between different equipment.

Rotator cuff injury is a common cause of shoulder pain and dysfunction. Finding out patients with suspected rotator cuff injuries through physical examination of the shoulder joints, MRI further assists in the diagnosis, and final surgical diagnosis and treatment are the current standardized procedures. How to apply multiple physical examination programs to make judgments sensitively, efficiently and accurately is a clinical problem that needs to be solved urgently.
