In this study we want to analyse the abduction brace-wearing time using a electronic sensor, which is implanted in the abduction brace. The patient´s will be informed about the sensor after completion of the abduction brace rehabilitation 6 weeks postoperatively.
After arthroscopic reconstruction of a rotator cuff tear the healing depends on a tension free positioning of the reconstructed tendon. Therefore a abduction brace is administered routinely for 6 weeks. The re-rupture rate of rotator cuff reconstruction is about 30%. One of the reason may be mechanical overuse caused by non wearing of the abduction brace. From experience we suggest that the abduction brace wearing behaviour differs among patients. The patient´s wearing compliance has been evaluated by Silverio et al. with a questionary but never with a sensor. In this study we want to analyse the patient´s abduction brace wearing compliance by using an sensor, which is implanted in the abduction brace and monitors the wearing time, which reveals the objective wearing time.
The sensor is a certificated sensor, which measures temperature in °C every 15 min. If the abduction brace is worn by the patient the body temperature can be captured by the sensor. If the measured temperature is over 33°C the sensor capture the time period as a "worn" time. With this measurements the abduction brace wear time should be captured objectively. A similar kind of sensors were used to evaluate the wearing time of scoliosis-braces in patients with adolescent idiopathic scoliosis (Miller DJ eta al., Morton A et al., Takemitsu et al.) With a questionary the patients are asked of the wearing time before they will be informed about the implanted sensor. This answer represents the subjective wearing time.
The first endpoint of the study is the evaluation of the objective and subjective abduction wearing time. The second endpoint is the evaluation of the correlation between compliance and subjective outcome.

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 ...
The overall goal of doing this study is to improve long term patient function and outcomes in the healing rates of Rotator Cuffs. The investigators would also like to see if this method ca...
There are two ways in which surgeons repair rotator cuff tears. An open method involves making an incision (cut) 5-6 inches in length in the skin and repairing the tear with the skin open,...
The cycloergometer is a mechanical device consisting of a bicycle frame fixed on a support base, designed to measure the amount of muscle work performed during exercise and the resistance ...
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 imm...
The major cause of rotator cuff tears in humans is thought to be tendon degeneration. Although some studies have reported chronic rotator cuff tear models in animals, few studies of chronic rat models...
Cellular remodeling in rotator cuff muscles following a massive rotator cuff tear is poorly understood. The aim of the current study was to provide histological evidence to elucidate the mode of muscl...
To evaluate the clinical and functional behavior of patients undergoing cuff tear arthroplasty at different stages of the disease.
Rotator cuff tears are among the most frequent upper extremity injuries. Current treatment strategies do not address the poor quality of the muscle and tendon following chronic rotator cuff tears. Hyp...
Rotator cuff pathology has been proposed to occur through intrinsic and extrinsic mechanisms. Hyperlipidemia has been proposed as a mechanism of intrinsic rotator cuff pathology. This prospective obse...
Compression of the rotator cuff tendons and subacromial bursa between the humeral head and structures that make up the coracoacromial arch and the humeral tuberosities. This condition is associated with subacromial bursitis and rotator cuff (largely supraspinatus) and bicipital tendon inflammation, with or without degenerative changes in the tendon. Pain that is most severe when the arm is abducted in an arc between 40 and 120 degrees, sometimes associated with tears in the rotator cuff, is the chief symptom.

The musculotendinous sheath formed by the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. These help stabilize the head of the HUMERUS in the glenoid fossa and allow for rotation of the SHOULDER JOINT about its longitudinal axis.
The tear-forming and tear-conducting system which includes the lacrimal glands, eyelid margins, conjunctival sac, and the tear drainage system.
A class of statistical procedures for estimating the survival function (function of time, starting with a population 100% well at a given time and providing the percentage of the population still well at later times). The survival analysis is then used for making inferences about the effects of treatments, prognostic factors, exposures, and other covariates on the function.
An alternative to REFRACTIVE SURGICAL PROCEDURES. A therapeutic procedure for correcting REFRACTIVE ERRORS. It involves wearing CONTACT LENSES designed to force corrective changes to the curvature of the CORNEA that remain after the lenses are removed. The effect is temporary but is maintained by wearing the therapeutic lenses daily, usually during sleep.
