Active clinical trials for "Rotator Cuff Injuries"

Rotator cuff tears (injury to the muscle or tendons which stabilise the shoulder) are one of the most common conditions affecting the shoulder. Small and medium sized rotator cuff tears can be managed with arthroscopic or keyhole surgery. Very large or massive tears are difficult to operate on and often have poor rates of healing. As a result surgeons have investigated the use of products to improve the outcome of surgery on massive tears. The product that the investigators are currently using to try to improve the outcome of surgery for massive rotator cuff tears is called a patch. The patch provides a scaffold to support the muscles of the rotator cuff. Studies of rotator cuff surgery using similar patches have found that recovery is improved and there is a lower rate of postsurgical problems. The aim of this study is to look at whether using the patch improves pain and the clinical function of the shoulder after surgery. In addition, the investigators would like to understand how the patch works. To do this the investigators will scan (take images of) the shoulder using magnetic resonance imaging to look at the muscle damage in the shoulder before and after surgery.

The optimal timing for surgical repair of traumatic rotator cuff tears is controversial. Today there are no prospective studies investigating the short to mid-term outcome after early arthroscopic repair of traumatic rotator cuff tears and the Swedish National Musculoskeletal Competence Centre requests more research to this subject. The investigators will follow 60 patients with acute rotator cuff tear undergoing early rotator cuff repair during the first year after surgery. The investigators hypothesise that the outcome after rotator cuff repair is good.

Patients undergoing surgery in beach chair position (BCP) are at risk for cerebral ischaemia. The impacts of arginine vasopressin (AVP) on haemodynamics and cerebral oxygenation are evaluated during surgery in BCP.

Patients diagnosed with partial thickness tears of the rotator cuff are sometimes surgically repaired, while other cases are not. It is unknown how patients fare over time without electing surgical repair and how outcomes differ by type of injury.

The purpose of this study is to determine whether the immobilization period is helpful for the better healing of repaired rotator cuff. The investigators hypothesis is that the longer immobilization after rotator cuff repair will help the healing of rotator cuff.

the aim of this study is to evaluate the duration of analgesia when either morphine or nalbuphine or both are used as adjuvants in sonar guided interscalene brachial plexus block for arthroscopic rotator cuff repair.

Objective: The relationship between rotator cuff tears and morphological features of the shoulder joint has not been fully explained. The earlier studies are usually done with two-dimensional radiography images, but joint positions and bone formations could not be fully evaluated in two-dimensional images. This study aims to evaluate the relationship between rotator cuff tears and critical shoulder angle (CSA) and acromial index (AI) values in three dimensions. Methods: This study examined computerized tomography of 24 rotator cuff tears (rotator cuff tear group) and 20 Bankart lesions, and no rotator cuff tears (control group). CSA and AI were measured on three-dimensional glenohumeral joint models obtained by three-dimensional reconstructions of computed tomography examinations. The investigators anticipate results of this study will guide clinicians in revealing the etiology of rotator cuff degeneration and determining the surgical method to be used for treatment.

The purpose of this study is to show that an augmentation with the DX Reinforcement Matrix from Arthrex is possible with the arthroscopic technique.

The hypothesis is that computer simulated bony impingement of the bone surrounding the spherical glenoid implant (the glenosphere) along the scapular neck on three-dimensional (3-D) computed tomography (CT) imaging analysis is predictive of the location of clinical scapular notching that develops following reverse total shoulder arthroplasty (TSA).

Few studies are considering acute traumatic rotator cuff tears in previously asymptomatic patients. The purpose of the current study was to investigate if delay of surgery, age at repair and the number of cuff tendons involved affected the structural and clinical outcomes.
