The Shouldr Joint

Rotator cuff surgery may be required to repair re-attach torn tendons to the shoulder. This may be followed by rotator cuff exercises after surgery to promote further healing and return of function.

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 labrum is a rim of soft tissue that makes the socket into more of a bowl-like shape. The labrum transforms the hard, angled surface of the glenoid into a deeper socket that molds to fit the head of the humerus. When the head of the humerus doesn't fit into the socket, this is when one will experience problems. The rotator cuff connects the humerus to

Moreover, the exercises above can help not only pitchers but also hitters, infielders, outfielders and catchers. Catching the ball and swinging the bat can also weaken the shoulders and put strain on your joints as much as throwing. The more flexible your shoulder is the better range of

This paper is going to be over rotator cuff injuries and what to do if this occurs to an athlete. The rotator cuff consists of four muscles which are the Subscapularis, infraspinatus, teres minor, and the supraspinatus and their associated tendons that insert into the Humerus. These groups of muscles are responsible for rotating the arm internally and externally as well as abducting the shoulder. The acronym for the four muscles of the rotator cuff is known as SITS. The best treatment for symptomatic, nontraumatic rotator cuff tears is unknown. The purpose of this trial was to compare the effectiveness of physiotherapy, acromioplasty, and rotator cuff repair for this injury. The way this trial worked was that 180 shoulders with the symptomatic,

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," ).

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.

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.

Instability Impingement. This occurs in younger patients, typically 15-30 years old. The rotator cuff is irritated because the shoulder is loose in the socket. This often happens in baseball pitchers, swimmers, and other throwing athletes. Shoulder instability can be classified into two different types, dislocations and subluxations. Dislocations happen when the head of the humerus completely pops out of the socket. The first few times this happens, it is usually with significant trauma although some people can have these without any injury at all. After that, it can get easier and easier for the joint to dislocate. Most shoulder dislocations are anterior - this means that the ball pops out the front of the socket. Subluxations are the feeling that the shoulder slips slightly out of socket, then immediately comes back in place. This often happens without any major trauma. Sometimes it happens in people who are very "loose-jointed". Sometimes these happen in just one direction like out the front, "anterior", and other times they happen out multiple directions like the front and back,

For the human joint anatomy project, our group decided to research and construct the elbow joint. The following is a report and summary of the project including roles taken, challenges faced, solutions derived, and ultimately, contribution and experiences of both partners.

The shoulder is a ball and socket joint which allows it a flexion and extension motion.

Contrast the major categories of joints, and explain the relationship between structure and function for each category.

A joint is the site where two skeletal elements connect(1). Joints can be classified by both structure and function. Structural classifications are based on the type of connective tissue binding the structures together and whether a joint capsule is present(2, 3). There are three structural classifications of joints; fibrous, cartilaginous and synovial. Functional classifications are based on the amount of movement present(2). There are three functional classifications of joints; synarthroses which are immobile, amphiarthroses which are slightly mobile, and diarthroses which are freely mobile(3).

Introduction: The glenohumeral joint has the most instability but most range of motion when compared to any other joint in the body. It requires the labrum, ligaments and capsule to maintain stability and function. A glenoid labrum tear disrupts this joint leading to pain and instability (Fitzcharles). Tears in the labrum are common in athletes who use repetitive motions of the shoulder, such as football quarterbacks, baseball pitchers and weightlifters. These tears can sometimes be mistaken as glenohumeral join instability, adhesive capsulitis and shoulder impingement (Painful).

The article, “Six-week Physical Rehabilitation Protocol for Anterior Shoulder Dislocation in Athletes”, by Ahmed Gaballah, Mohamed Zeyada, Adham Elgeidi, Eadric Bressel was to find a design physical rehabilitation program with aim to improve joint strength and also range of motion, by using elastic band and resistive exercise as an intervention strategy. The problem of this study were started with one wondering question, “It’s a possible and necessary or not just by need only six week rehabilitation program for individuals diagnosed with first-time shoulder dislocation?”. Based on the abstract of this journal, it’s clearly just not as simple study and require a deep research. The author firstly stated the definition of shoulder dislocation.
