Easy Way to Remember Rotator Cuff Muscles
If my dad tells me about the hockey game that led to him tearing his rotator gage one more fourth dimension, I'thou going to tear the residual of his arm off and beat him with it. I'd rather he'd relive his glory days a fiddling less and focus more on being seen by a doctor for his rotator cuff issues. But because he never got adequate help with his rotator gage tear when he was younger, I'm doomed to a lifetime of watching His Stubborness wince every time he scratches the dorsum of his head. Dads. Am I correct? What is the rotator gage, though, and why does an injury to information technology accept such an impact? Read on! If you're my dad, read on so please get see your dr.. The rotator cuff is a group of muscles and tendons that surround the shoulder joint. These muscles continue the top of the upper arm in the shoulder socket by forming a "gage" that not only holds the arm in place merely helps it motion in various directions. The rotator cuff muscles hold the brawl at the top of the humerus firmly in the glenoid fossa. The rotator gage muscles are the supraspinatus, subscapularis, infraspinatus, and teres minor. Origin Insertion Action Subscapularis Subscapular fossa Lesser tubercle of the humerus Medial rotation of the head of the humerus; prevents inductive displacement of the humerus Supraspinatus All of the supraspinatus fossa Greater tubercle of the humerus Assists the deltoid in abducting the arm; stabilizes the glenohumeral joint Infraspinatus Infraspinatus fossa on the posterior surface of the scapula Greater tubercle of the humerus Laterally rotates the upper limb; stabilizes the glenohumeral joint Teres small-scale Lateral edge of the scapula Greater tuberosity of the humerus Lateral (external) rotation of the humerus; helps protect and stabilize the shoulder articulation When my dad was in high school, he played on our hometown hockey squad and concluded up… in a fight? In a dogpile? A ninja boxing? I don't know, I feel similar the story'southward changed over the years. Regardless, he tore his rotator cuff while tending goal and, thanks to our family'southward particular strain of stubbornness, never got it properly checked out. It's been plaguing him e'er since. Tears are typically categorized in two ways: if they have partial thickness or full thickness, and if the tears are traumatic or degenerative. Gradual degeneration, similar repetitive overheard motion of the shoulder (call up of baseball pitchers), or sudden traumatic events (my dad at hockey) tin can tear one of the musculus tendons of the rotator cuff. Information technology'south ordinarily a torn supraspinatus that ends upwards causing the majority of the issues. Rotator cuff tears usually occur at the insertion point on the head of the humerus and then that the tendon will no longer fully attach to the bone. Desire to see information technology in all its gruesome action? You're in luck! We've got a super brusk blitheness almost information technology: Symptoms of a rotator gage injury include pain, decreased range of movement in the shoulder, and muscle weakness. Treating a rotator cuff injury can range from easy (physical therapy being the near common) to invasive (surgery). I've been hounding my dad to have surgery on his shoulder for years, but he hasn't budged however. I'm non sure what he'south waiting for. At that place are several types of surgery to treat the rotator cuff, including open up tendon repair – in which a surgeon reattaches the tendon to the os – and shoulder replacement – in which a surgeon installs the ball office of the bogus articulation onto the shoulder bract and the socket part onto the arm bone (but this is reserved for only the most massive rotator cuff injuries coughdadcough). Small rotator cuff injuries will heal on their own with plenty of ice, rest, and daily shoulder exercises. If y'all exercise end upwardly suffering a more involved injury, do literally the reverse of my dad and accept it evaluated by a doctor. It may be one less story to tell at family unit gatherings, but y'all'll be saving yourself a lifetime of pain. Be sure to subscribe to theVisible Body Blog for more anatomy awesomeness!
