RCT is a common disease. According to general population surveys, the prevalence of rotator cuff tear is 25 % in those older than 50 years of age and 20 % in those older than 20 years of age (1). The rotator cuff is a group of 4 muscles and their tendons supraspinatus, infraspinatus, teres minor, and subscapularis (2). These muscles connect the upper-arm bone, or humerus, to the shoulder blade. The important job of the rotator cuff is to keep the shoulder joint stable. RCT can be caused by degenerative changes, repetitive micro-traumas, severe traumatic injuries, and secondary dysfunctions. Falling on an outstretched hand, unexpected force when pushing or pulling or during shoulder dislocation can cause traumatic injury to the rotator cuff. …show more content…
Dynamic scapular dyskinesis is detected by asking the patient to raise and/or abduct both arms repeatedly in a rhythmic motion, until fatigue of the scapular stabilizers results in failure to keep the scapula well positioned in relation to the thoracic wall. Active scapular retraction and elevation are checked. The next step is to look for muscle atrophy and remember active and passive range of motion should be examined and compared with the non-injured shoulder. It is easy to detect muscle atrophy of the infraspinatus viewing from the back of the patient, whereas the supraspinatus is covered by the trapezius. Atrophy of the shoulder muscles is a common finding in patients with rotator cuff tears. c- Palpation: Palpation of the cuff tendon defect is a very useful examination. Rent Test, which is placing the tip of the finger just anterior to the acromion to palpate the defect of the cuff tendon. At the same time extend patients arm and internally and externally rotates to palpate rotator cuff tendons. The sensitivity and specificity of this palpating of the cuff tendon defect for the diagnosis of full-thickness rotator cuff tears were 96 and 97%, respectively, which were equivalent to the sensitivity and specificity of magnetic resonance imaging (MRI) or ultrasonography
2. During inspection of the patient’s affected shoulder, name at least three key clinical aspects that you need to observe on both shoulders that would suggest any pathology or abnormality on the shoulders. From the three clinical aspects that you observed, explain what each of the findings would indicate concerning the pathology of the shoulder. For example if the shoulder is
Your rotator cuff consists of four muscles in your shoulder that allows you to move your arm away from your body. These muscles have tendons, which connect them to the head of your upper arm bone or humerus. When a tear occurs in these muscles, you will experience extreme pain on motion. A rotator cuff tear is also extremely painful at night. If left untreated, it may result in arm weakness.
Walch et al first described the internal impingement as an intraarticular impingement of the rotator cuff in the abducted and externally rotated shoulder. With 90 degrees of both abduction and external rotation, the articular surface of the posterior superior rotator cuff becomes pinched between the labrum and the greater tuberosity.5 The authors separated the labral lesions from SLAP lesions which extended anteriorly to the biceps anchor at the supraglenoid tubercle, concluding that internal impingement may be responsible for a subset of patients with isolated posterior SLAP tears.5
Baseball is America's pastime. Everyone in this country knows a person who plays the game and the struggles they face throughout their entire baseball endeavors. Baseball is an overhead throwing sport that requires countless amount of repetition in order to perfect the art of throwing a baseball with different spins and velocities. Because baseball has become a non-season based sport in this modern era, it has risen health risks to the elbows of athletes that play continuously. The Ulnar Collateral Ligament, commonly coined as the Tommy John Ligament, is the
Four muscles that are attached to the shoulder blade make up the rotator cuff. These muscles work together to ensure the shoulder moves and rotates properly. If the muscles become inflamed or torn, you will struggle
The rotator cuff refers to the group of muscles and tendons in your shoulder that connects your shoulder blade to your upper arm.
Damage to any of these muscles and the ligaments that attach these muscles to the bone can occur because of multiple different reasons. These reasons could be an acute injury, chronic overuse, or gradual aging. The damage can cause a lot of pain and disability with decreased range of motion and use of the shoulder. The shoulder is made up of a ball and socket joint that allows the arm to move in many different directions. When the rotator cuff is hurt a lot of different things could occur things including; Pain and spasm limit the range of motion of the shoulder, Fluid build up within the joint due to inflammation limits movement, Arthritis and calcium deposits that form over time which could limit the range of motion. The main thing that causes rotator cuff injuries is injuries to muscle tendon units which are called strains, and these are classified by the amount of damage to the muscle or tendon fibers. There are a few grades of this injury which include grade 1 which involves stretching of the fibers without tearing. Grade 2 involves injuries of partial muscle or tendon tearing, while grade 3 which is the worse is a complete tear of a muscle or tendon. An acute rotator cuff tear can happen from a sudden raising of the arm against resistance or example like when your falling and you put your arm out to try and catch yourself, this type of injury requires a significant
There are many more terms and concepts in throwing a baseball then the wind-up, cocking, acceleration, and the follow through. There is also the stride, your pelvis, rotation, deceleration, force, gravity, resistance and speed. (Maranowski). Within the shoulder, there are three major bones used. They are the clavicle, humerus, and the scapula. Another major component of the shoulder while throwing is the rotator cuff. The rotator cuff is made up of four small muscles which are the subscapularis, supraspinatus, infraspinatus, and the teres minor. The main responsibility of the rotator cuff is for the stability of the shoulder joint. It holds the humeral head in the glenoid socket during early abduction while throwing. (" biomechanics of," ).
Inspection of the right shoulder joint reveals atrophy. Movements are restricted with flexion to 90 degrees limited by pain and abduction to 75 degrees limited by pain. Hawkin’s test, Neer’s test, Shoulder crossover test, Empty Cans test, Lift-off test, and Apprehension test is positive. On palpation, tenderness is noted in the acromioclavicular joint and subdeltoid
Millions of people across the United States suffer from either Bursitis or a rotator cuff injury every year. Although sometimes the two can be misconceived, they are very different in all actuality. Bursitis is the inflammation or irritation of the bursa. A bursa is a fluid-filled sac used as a bumper near the joints to reduce friction. There are many bursae located in your body, some of which being in the hip, shoulder, wrist, and elbow. However, a rotator cuff injury only affects the shoulder area of the body. The “rotator cuff” is composed of the supraspinatus, infraspinatus, subscapularis, and teres minor muscles. There is only one main way to be diagnosed with Bursitis and it happens when you overuse a joint in sports or on the job. You can put the bursa under pressure for a long time, thus causing the bursa to become inflamed.
The rotator cuff is a group of 4 muscles, the supraspinatus, infraspinatus, subscapularis, and the teres minor. These muscles helps to lift your shoulder up over your head and also rotate it toward and away from your body. Unfortunately, it is also a group of muscles that is frequently injured by tears, tendonitis, impingement, bursitis, and strains. The major muscle that is usually involved is the supraspinatus muscle. Rotator Cuff Injuries are usually broken up into the following categories.
*insert article *attachedBesides being able to see the inside of a shoulder, doctors use different physical tests to evaluate the shoulder in order to determine what type of injury and how severe an injury may be. One such test was recently developed by Dr. Carl J. Basamania at the Womack Army Medical center in Fort Bragg, N.C. The test was developed to evaluate shoulder instability in a patient. During the test the Dr. or examiner stands next to the patient who is to lay flat on his/her back. The hand of the examined should is held firmly by the examiner. The examiner then pushes against the clavicle to stabilize th scapula, while they also gently hold the pectoral muscle with their thumb in order to be able to assess relaxation. The examiner then rotates the arm form neutral to full external rotation. If the patient has AIGHL incompetence there is a lack of tightening as the arm reaches full external rotation. The test has appeared to be highly accurate and may be of value to Dr.'s and surgeons alike. After doctors have determined what type and what degree of injury a patient has sustained using various tests it is on to the next step, rehabilitation.
The purpose of this study was to discuss the disable throwing shoulder with a focus on the SICK scapula, scapular dyskinesis, the kinetic chain, and rehabilitation. SICK stands for Scapular malposition, Inferior medial border prominence, coracoid pain and palposition, and dykinesis of scapular movement. Appearing on examination as if one shoulder is lower than the other, SICK is asymmetric malposition of the scapula in the dominant throwing shoulder. They are grouped into 3 clinically recognizable patterns of scapular dyskinesis. Type I which is inferior medial scapular border prominence and type II, medial scapular border prominence. While those are 2 most commonly associated with labral pathology, type III is towards impingement and rotator
A shoulder is one of the most complex joints of the body. The anatomy of the shoulder starts where the humerus fits into the scapula almost as if it were mimicking a ball and socket. The scapula has a little tip of itself overlooking the tendons of the shoulder called the acromion and a bit of itself fanning out, a part called the coracoid. Also connected to the scapula is the clavicle or collarbone. Another very important component to the shoulder is the rotator cuff, this is the most vital part to rotator cuff tendonitis. It is composed of four muscles and of various tendons that surround the shoulder socket that allow it to connect the upper arm and the shoulder blade together. Protecting the rotator cuff is is a small sac of fluid called a bursa. The humerus fits relatively loosely into the shoulder joint. This gives the shoulder a wide range of motion, but also makes it vulnerable to injury.
The most common muscle to rupture is in the group of muscles of the rotator cuff. The rotator cuff is a part of the shoulder that is composed of four muscles which keep the head of the humerus in the shoulder socket. The four muscles that make up the rotator cuff are: the supraspinatus (which is the most common muscle to rupture), infraspinatus, teres minor, and subscapularis. There are four levels of a rotator cuff tear: a grade one, a small and partial tear (less than 1cm deep); a grade two, a medium and partial tear (1-3cm deep) which does not exceed one-half of the tendon thickness; a grade three, a large but partial tear (3-5cm); and a grade four, a massive and partial or complete tear (greater than 5cm deep). The symptoms of a rotator cuff tear are: pain at rest and at night, particularly if weight is on the affected shoulder, pain when lifting and lowering the arm or with specific movements and a change in the range of motion. There will be weakness when lifting or rotating the affected arm with possible crepitus or crackling sensation. Although there are multiple degrees of a rotator cuff tear, the symptoms are relatively similar with the intensity of the pain varying throughout the extent of the injury. Unlike the previous injuries, this injury is normally treated with surgery. Whether the
