Answer the following questions related to the scenario (33 marks).
1. What tissue is the shoulder joint capsule made of and how does this change in a frozen shoulder? (2 marks) The shoulder joint capsule is composed of connective tissue. It’s role is to provide strength, support and a wide range of motion. This changes in a frozen shoulder as the capsule becomes thick and stiff whilst restricting movement at the shoulder joint.
2. What is a bone spur and how does it occur? (1 mark)
Bone spurs are bony protrusions that develop along the bone. Bone spurs often form when bones meet each other. Bone spurs occur when there is inflammation. This includes problems such as tendonitis or arthritis.
3. Explain what is meant by external rotation of a limb joint? Which muscles produce this in the arm? (2 marks) External rotation is outward movement or turning away from the midline of the body. For example, when the leg is externally rotated, the toes are pointed outwards away from the body. Muscles that produce external rotation of the arm include the infraspinatus, supraspinatus, and the teres minor.
4. Define the term dermatome and state along which spinal dermatome does the pain radiate towards the hand (2 marks) A dermatome is the area of the skin supplied by nerves from a single spinal root. The C5-C6 spinal dermatome nerves are responsible for

What structure passes through the region outlined by the yellow arrow and how does it contribute to the pain experienced in the anterior compartment of the arm by Bruce? (3 marks) The structure passing through the yellow arrow is the humerus. It contributes to the pain at the anterior compartment of the arm by the long head tendon of the biceps muscle grinding against the scapular muscle. This leads to the ongoing instability of the humerus giving Bruce a large chance of a subluxated humerus. The superior labrum will also grind up against his inflamed bursa which is why Bruce has decreased range of motion and lots of
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
Once inside the elbow the unlar nerveis recognized, lifted out, and moved to provide greater access to the joint. This is the "funny bone" nerve and it runs inside the ulnar groove.
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,
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.
The baseball star, David Wright, is having another setback in his game because the newly diagnosed right shoulder impingement that requires immediate care and treatment. According to Mets General Manager, Sandy Alderson, Mets third baseman will have to sit out the games for the following few weeks and concentrate on the complete recovery.
The elbow joint moves in the saggital plane frontal axis of the body. This axis only allows the movement of flexion and extension of the elbow.
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.
Rotator cuff surgery affects the function of the shoulder. It is very painful injury and there is loss in strength. If the rotator cuff tendon becomes inflamed or is partially torn, it can be painful and will most limit shoulder movement. This injury occurs from a sudden impact, like falling on your arm which might accrue in motocross, snowboarding, playing football, and similar collision sport. Activities that might cause overload to the tendon have a possibility to tear the tendon. Other ways a rotator cuff can tears is from old age and over use over the years.
There are about 600 muscles in the body working together to create movement. Muscle contractions pull both ends of the muscle towards one another. One bone attached to each muscle is always more stabilized than the other. The less stabilized bone moves during muscle contraction due to the weaker stability. The points of attachment determine which bone will move. The least movable part is called the origin; it is the part that attaches closer to the midline of the body. This leaves the most movable part called the insertion. Each of these points can be identified in individual muscles to assist trainers in understanding how the muscles and joints work together to create motion.
The left shoulder abduct concentrically by the deltoids to provide balance for the body. The cervical spine flex laterally sternocleidomastoid. The lumbar spine of the body flex laterally by concentric contractions of the rectus abdominis. The shoulder girdle adducted by isometric contractions of the middle trapezius, upper trapezius, and rhomboids. The elbow extends and flex by isometric contractions of the triceps brachii and biceps brachii on both sides. The wrist extends concentrically by the extensor carpi radialis longus, extensor carpi radialis brevis, extensor pollicis longus, extensor digiti minimi, extensor indicis, extensor digitorum, and extensor carpi ulnaris. The metacarpophalangeal and interphalangeal are extended by concentrically by extensor pollicis brevis, extensor pollicis longus, extensor digiti minimi, extensor indicis, and extensor digitorum on left and right side of the
The shoulder is made up of two bones: the ball end called the humerus and the socket end called the scapula. It is held together by a semi complex series
Shoulder pain can range from mildly unpleasant to completely debilitating. It can be easy to put off treatment if you don't live within close proximity to a skilled shoulder doctor, but by doing so, you run the risk of having the condition worsen. Founded by Dr. Robert E. McLaughlin, North Shore Shoulder offers world-class orthopedic shoulder care. The facility is based in Beverly, MA, but if you need help with shoulder pain and aren't close enough to come in for an initial consultation, you can send your X-rays, CAT scans, or MRIs in to Dr. McLaughlin for a complimentary review. When doing so, keep the following guidelines in mind:
Your arm is brought back to your ear by your posterior deltoid horizontally adducting your glenohumeral joint which causes your anterior deltoid to be stretched in order to slow the external rotation and your pectoralis major is also stretched to slow the horizontal adduction, your body is turned by your back extensors and obliques.
