Active clinical trials for "Rotator Cuff Injuries"

In accordance with national guidelines surgical repair of rotator cuff tear is the first-line strategy only in young patients, depending on tear size, fatty infiltration of rotator cuff muscles and articular status. In appropriate situations, a satisfactory result is expected in more than 80% of cases with a very good long-term outcome. On the other hand, the first-line strategy in older patients is conservative as the main objective is the treatment of pain and stiffness of the shoulder which can be achieved at least in the short-term with general and local medications and physiotherapy. In addition, poor prognostic factors such as massive tears and muscle fatty infiltration or atrophy, are more frequently present in those patients, leading to poor results of surgical treatment and a high risk of iterative tear after repair. Because of a lack of evaluation, there is currently no identified prognostic factor of medical treatment and on the other hand no clinical situation in which a surgical repair is mandatory. Therefore, investigator designed this study as an observatory with the follow up of patients with a symptomatic rotator cuff tear treated conservatively.

Adequate upper limb function is critically important to maintenance of independence and prevention of disability in older adults. The goal of this work is to identify factors that contribute to rotator cuff rupture and improved outcomes for repair. Ultimately, the investigators seek to identify patients most at risk for rupture and to guide clinicians on optimal surgical and rehabilitation strategies. This pilot study will quantitatively characterize the morphological (muscle volume and fatty infiltration) and functional (shoulder isometric joint strength, movement when performing typical task) changes in the muscles of the rotator cuff following supraspinatus tear and surgical repair. The investigators hypothesize that patients with supraspinatus tear will have reduced muscle volume and increased fatty infiltration of rotator cuff muscles compared to their contralateral arm and age-matched controls, which will increase following surgery. The investigators further hypothesize that isometric joint strength in these individuals will be associated with muscle volume and the degree of fatty infiltration, and that older adults with a rotator cuff tear will use a restricted range of motion to accomplish functional tasks. This study emphasizes muscle function and composition with application to rehabilitation of upper limb function, which complements the theme of the Pepper Center.

The purpose of this project is to provide information which can help us understand what happens over time to rotator cuff tears. In this study, the investigators will follow a population of people with rotator cuff tears that do not hurt (asymptomatic) and to establish the probability that an asymptomatic rotator cuff tear, identified in the context of contralateral symptoms, will become symptomatic over time. To determine with ultrasound the probability that a rotator cuff tear will enlarge over time. To determine if symptom progression correlates with enlargement of the rotator cuff tear and/or degenerative changes on radiographs. In order to obtain data, study subjects will be recalled for follow-up at 1 year time points over a 5 year period. The study subjects will have repeat physical exam, ultrasound and radiographic examinations. A control group of normal patients will also be followed for comparison.

To evaluate the association between rotator cuff tear and the proximal migration of humeral head

This study is aprospective cohort study on the outcome of a combination of bone marrow stimulation and modified suture bridge in the arthroscopic treatment of small and medium rotator cuff tear. The patients with small to medium rotator cuff injuries (less than 3cm in diameter) requiring arthroscopic surgery were collected. The patients were followed up before and 6 weeks, 3 months, 6 months and 12 months after surgery, including pain, functional score, joint range of motion, MRI and CT findings, complications and other quantitative and qualitative indicators. The self-control and intra group analysis were performed to evaluate the treatment effect; and the correlation analysis was performed on the treatment results To determine the important factors affecting the therapeutic effect.

A comprehensive understanding of healthy shoulder motion is a valuable contribution to the academic literature and provides a basis of comparison for various shoulder pathologies and treatments. However, the medical community is primarily interested in how pathology affects shoulder function and the underlying musculoskeletal reasons for impaired function associated with specific pathologies. Rotator cuff tears (RCT) provide an excellent model to study shoulder biomechanics because RCTs can cause significant functional impairment and can be quantified in size and location using standard clinical imaging techniques. Upon completion of this study a comprehensive database of three-dimensional joint angles and EMG patterns of the structures of the shoulder joint complex of dominant and non-dominant during common activities of daily living will be available for healthy subjects and those of subjects whose dominant limbs are impaired by rotator cuff tears. These data will show normal muscle activations and movement patterns required to complete activities of daily living and compare them to the movement, and muscle activation patterns of persons who exhibit muscular and movement dysfunction due to rotator cuff tears.

Through a prospective randomized study the aims of this study is to analyze the impact of 3 types of rehabilitation protocols on the Optimization of the post-operative clinical and anatomic healing of the rotator cuff. After an arthroscopic repair of a stage 1 or 2 supra-spinatus tendon rupture, patients will be included in 3 groups (98 patients per group): strict immobilization for 6 weeks then active rehabilitation, or 3 weeks of immobilization then 3 weeks of passive motion before active rehabilitation, or immediate passive motion for 6 weeks and then active rehabilitation. Patients will be evaluated clinically at 6 weeks, 3 months, 6 months and 1 year and an arthro-CT will be performed at 1 year. The investigators will evaluate: constant score and rate of tendon healing.

The purpose of this study is to evaluate reverse total shoulder arthroplasty patients preoperative objective measurements and operative objective measurements to determine if there is any effect to postoperative outcomes. Patients who were 18 years old or greater at the time of surgery were followed clinically and radiographically to determine best practice and optimal treatment and technique, risk and rate of complication, and postoperative outcomes.

This study aims to evaluate the effect of bone marrow concentration on healing of rotator cuff tear by comparing clinical and imaging outcomes between patients receiving arthroscopic repair with intraoperative bone marrow concentration and those receiving arthroscopic repair only.

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
