Rotator cuff is a network of four muscles that form a covering of tendon around the head of the humerus. It keeps arm in shoulder socket and helps in lifting and rotating movement of arm. Tearing of one or more of the rotator cuff tendons can lead to partial or complete detachment of rotator cuff to the head of the humerus. This will cause pain and difficulty to the person while performing many daily activities, like combing or getting dressed.
Characteristics of Rotator cuff tear:
Cause: Fall on outstretched arm OR jerk motion while lifting heavy object OR shoulder injuries OR age related wearing down of the tendon OR repetitive stressful activities.
Symptoms: Pain at rest, at night, while lifting arm, while lowering arm along with disability and crepitus or crackling sensation on shoulder movement.
Treatment: Shoulder arthroscopy is recommended in cases where non-surgical management does not relieve the patient. Arthroscopic surgery is performed to repair a torn rotator cuff by re-attaching the tendon to the head of humerus.
