|
|
Term
|
Definition
| a bony process projecting from the scapula toward the sternum. Several ligaments attach to the coracoid, as do the tendons of the coricobrachialis muscle and the short head of the biceps |
|
|
Term
|
Definition
| a muscle with origin from the lateral third of the clavicle, the lateral border of acromion process, and the lower border of spine of scapula, with insertions to the side of the shafte of the humerus, with nerve supply from the axillary nerve from the 5th and 6th cervial nerves throught the brachial plexus, and whose action causes the abducation, flexion, extenstion, and rotation of the arm. |
|
|
Term
|
Definition
| displacment of a body part, especially the temporary displacement of a bone from its normal position within a joint. |
|
|
Term
|
Definition
| a term that is commonly used to fefer to the infraspinatus and teres minor muscles which affect external rotation of the shoulder. |
|
|
Term
|
Definition
|
|
Term
|
Definition
| the articular depression of the scapula entering into the formation of the shoulder joint |
|
|
Term
|
Definition
| the smooth round articular surface of the proimal humerus bone |
|
|
Term
|
Definition
| the bone of the arm, articulating with the scapula above and the radius and ulna below. |
|
|
Term
|
Definition
| term used when referring to the shoulder to describe the concept of pathologic pressure on the rotator cuff from part of the shoulder blade as the arm is lifted. |
|
|
Term
|
Definition
| an intrinsic (scapulohumeral) muscle fo the shoulder joint. The tendon of this muscle contributes to the formation of the rotator cuff; origin - infraspinous fossa of scapula; insertion- middle facet of greater tubercle of humerus; action- extends arm and rotates laterally; its tonic contraction helps to hold the head fo the humerus in the shallow glenoid fossa; nerve supply-suprascapular(5th/6th crevical spinal nerve |
|
|
Term
|
Definition
| refers to the subscapularis muscle which affects internal rotation of the shoulder. |
|
|
Term
|
Definition
| a rim or cup of cartilage that contributes to shoulder stability by deepening and increasing the glenoid surface area, providing attachments for the shoulder capsule and various ligaments and tendons. |
|
|
Term
| multidirectional instability (MDI) |
|
Definition
| shoulder instability in patients who have generalized looseness of the supporting ligaments that surround the shoulder's glenouhumeral joint. Laxity can be a congential condition or a condition that developed over time from repetitive activities that stretch the shoulder capsule such as overhead sports. |
|
|
Term
osteonecrosis
avascular necrosis |
|
Definition
| necrosis of bone tissue due to impaired or disrupted blood supply marked by severe pain in the affected region and by weakended bone that may flatten and collaps. |
|
|
Term
|
Definition
| exercise that emphasizes maintaining range of motion rather than strengthening. During a passive shoulder exercise the surgical shoulder and arm remain loose while the unaffected arm provides the power to take the shoulder through a range of motion. |
|
|
Term
|
Definition
| a supporting and strengthening structure of the shoulder joint that is made up of part of its capsule blended with tendons of the subscapularis, infraspinatus, suprasspinatus, and teres minor muscles as they pass to the capsule or across it to insert on the humerus. |
|
|
Term
|
Definition
| either two large flat triangular bones forming the back part of the shoulder |
|
|
Term
|
Definition
| rare condition caused by nerve injury or another disorder affecting the shoulder, "winging" abnormal protrusion of a part of the scapula. (Da shoulder's blades) |
|
|
Term
|
Definition
| a tear of the superior labrum of the shoulder. SLAP = Superior Labrum Anterior Posterior. The arm is forcefully bent inward at the shoulder, the humerus acts as a lever and tears the long head of the biceps tendon and labrum cartilage from the glenoid cavity in a front to back direction (anterior-posterior) |
|
|
Term
|
Definition
| 1/4 rotator cuff muscles. Located on the undersurface of the scapula and connects at an area on the proximal humerus bone called the lesser tubercle. Responsible for internal rotation of the arm at the shoulder. |
|
|
Term
|
Definition
| 1/4 of rotator cuff muscles. Sits on the superior posterior scapula in an area known as the supraspinatus fossa connects to the proximal humerus bone at the greater tubercle. Contributes to stabilization of glenohumeral joint. Most often injured rotator cuff muscle. |
|
|
Term
|
Definition
| 1/4 of rotator cuff muscles, originates from the lateral border of the scapula and inserts into the proximal humerus at the greater tubercle contributes to the shoulders external rotation strength. |
