Shoulder Morphology

1244 Words5 Pages

A variety of shoulder disorders are associated with the acromin. (GILL, MCIRVIN, KOCHER et al., 2002; TUCKER and SNYDER, 2004; HAMID, OMID, YAMAGUCHI et al., 2012) and its morphology is an important tool in pathology diagnosis. The shoulder is a complex joint that allows movements of flexion, extension, abduction, adduction, external and internal rotations. (Describe the anatomy of the joint- refer last, Grays anatomy)
Variations in the architecture of the acromium is the primary etiologic factor in impingement syndrome’s pathogenesis, leading to potential rotator cuff disease. The volume of the subacromial space is reduced due to differences in the development and morphology of the acromion, the presence of anterior acromial spurs and inferior …show more content…

The anterior tip of the acromion, the coracoacromial ligament, and the coracoid process have been described as sources of impingement. The relationships of the supraspinatus tendon, the biceps tendon, and the greater tuberosity of the humerus with the coracoacromial arch were demonstrated through various arcs of shoulder motion in autopsy subjects. Biceps tendon impingement occurred predominantly against the lateral free edge of the coracoacromial ligament. Impingement of the supraspinatus tendon and greater tuberosity was demonstrated primarily against the acromial end of the coracoacromial ligament and the anterior tip of the acromion during arcs of flexion and internal rotation. Formation of traction osteophytes on the anterior acromion in patients with chronic impingement symptoms may due to stretching of the coracoacromial ligament by the greater tuberosity passing beneath it. This may explain the (Burns and Whipple, …show more content…

In the last 7 years, they have treated 20 patients with a previously undescribed "keeled" acromion. The keel refers to a central, longitudinal, downward sloping spur on the acromial undersurface. Patients with a keeled acromion are at significant risk of bursal-sided as well as full-thickness rotator cuff tears. All patients in this series had significant bursal-sided tears, and 12 of 20 patients (60%) had full-thickness rotator cuff tears associated with an acromial "keel." In addition, patients with a keeled acromion are younger (average age, 52.7 years) than would be expected for patients with rotator cuff disease. Often these patients are misdiagnosed, and effective treatment is delayed. Diagnosis of a keeled acromion relies on a high level of suspicion, as well as knowledge of clinical and radiographic signs consistent with an acromial

In healthy individuals, anterior rotation of the innominate occurs during extension of the freely swinging leg. When the innominate anteriorly rotates, it glides inferiorly down the short arm and posteriorly along the long arm of the SIJ. In non-weights bearing an arthrokinematic glide between the innominate and the sacrum occurs during posterior rotation of the innominate and is physiological (i.e., follows the articular surfaces). In weight bearing, the close-packing of the SIJ precludes this physiological glide. Sacral nutation produces the same relative arthrokinematic glide as posterior rotation of the innominate (inferoposterior motion of the sacrum is the same as anterosuperior motion of the innominate); sacral counternutation produces the same arthrokinematic glide as anterior rotation of the innominate (anterosuperior motion of the sacrum is the same as inferoposterior motion of the

The purpose of this essay is to describe structure and function of the tendon, present a discussion on the process of pathophysiological Tendinopathy and provide a review of known intervention used to manage or treat both acute and chronic tendinopathies. Tendons act to serve a connective tissue linking muscle to bony attachment points and in the case of the intermediate tendons that will act to link a muscle belly to another (Benjamin and Kaiser, et al). Tendons are a uniaxial and assist in force transmission thus being able to withstand external forces from multiple planes and angles (Kannus, 2008). Tendons are also responsible for storage of power and changes in the mechanical energy of the body of which in turn reduces muscular work by

Since the condition required an immediate treatment, Dr. Tehrany recommended and promptly scheduled a shoulder surgery to repair the rotator cuff tear. Later that year, Lt. Scalzo visited Manhattan Orhtopedic Care for a second time, this time for a stiffness and pain in his right shoulder. Since Dr. Tehrany efficiently treated Lt. Scalzo’s left shoulder, there was no doubt that he will be the

Brachialis or Anterior Capsular Elbow Strain With Rehab Brachialis or anterior capsular elbow strain is also known as climber’s elbow. The brachialis muscle is important for flexing the forearm at the elbow joint. This condition occurs when the brachialis muscle in your upper arm is inflamed or when you have a strain in the front of your upper arm (anterior compartment). This condition causes pain in the front of the elbow. This condition is usually an overuse injury that at first causes minimal pain, and slowly progresses.

Symptoms o Shoulder pain o Pain in the outer side of the elbow o Pain in the inner side of the elbow o Pain in the wrist o Pain at the back of the heel Although in most cases the exact reasoning of tendonitis is unknown, when the cause is known it can be one of two reasons either “overuse” or “overload”. Overuse happens when a particular body motion is repeated too often and overload happens when the level of a certain activity e.g. weightlifting.

The general purpose of the surgery is to remove the torn ligament and replace it with a tendon that is used less, most often used is the palmaris(Lasky). The palmaris is a tendon that is found within your wrist(Lasky). The surgery is continually successful, around ninety-seven percent of pitchers return to their previous level of success before being injured (Hoffman et al. 1). It is good that the success rate is high, however that leaves three percent that may never get to play at that level again. Research shows that around seventy major league pitchers’ arms have not worked properly since having the surgery(Apstein).

(WebMD) When these injuries develop in baseball players, in order to assure that they are playing to their full ability a medical procedure is necessary. The procedure calls for a ligament replacement in the elbow which the injury has occurred. The first time this procedure had been done was in 1974, by a man named Dr. Frank Jobe, and it was performed on Los Angeles Dodgers pitcher, Tommy John, who experienced a complete tear of the UCL

In the following essay "Throwing Like a Girl", author James Fallows adresses the issue of stereotypes between men and women. Many people feel as if doing anything "like a girl", is a bad thing. Fallows included photos of the 42nd President of the United Sates, and his wife, Hillary Clinton, throwing a baseball at two different baseball games. The pictures showed Hillary, as he descibed, "Throwing Like a Girl", and her husband Bill, in a perfect position throwing the ball. It was said, by a well-educated woman, that men and women had structural differences in the rotary cuffs of the arms and shoulders.

There's not enough space to actually rotate your joint properly and this frozen shoulder will be the outcome. Commonly this only occurs in the ages of 40 to 60 years old and it can include swelling stiffness and pain in the shoulder area. This joint is prone to inflammation and is common in people who are diabetic and may

4) Compare and contrast somatic and visceral pain. (5 points) 5) Visceral Pain: Visceral pain is pain that is in the internal organs and heart muscle.6 However, not all viscera is sensitive to pain such as liver, lung, and kidney parenchyma.6, 8 This is most likely due to the fact visceral organs are innervated by receptors that do not reach consciousness.8 While this type of pain is poorly localized, visceral pain corresponds to a dermatomal pattern.6 Poor localization of visceral pain is thought to be a result of the few sensory afferent compared to somatic.8 This pain is also associated with an autonomic nervous system response which could result in a change of vital signs, unexplained sweating and skin pallor.6 Somatic Pain:

Physiological Basis: Damage (tearing/stretching) to the ulnar (medial) collateral ligament or radial (lateral) collateral ligament will increase joint-play due to laxity and hypermobility at the joint in the direction of the varus/valgus force. The strength of these ligamentous passive constraints will be jeopardized in resisting tensile forces compared to normal, as evident with excessive varus or valgus motion of the tested elbow compared to the normal contralateral
