The Shoulder
Cards in this deck (18)
- 1the acromion processAn extension of the spine of the scapula that hooks anteriorly. It is fairly prominent.
- 2the coracoid processcan be found just inferior to the lateral end of the clavicle and is a small hook-like structure
- 3the spine of the scapulaa prominent plate of bone slightly inferior to the superior border of the scapula
- 4medial border of the scapulathe most inner border of the scapula can be found by palpating the spine of the scapula medially until it falls of the end and onto the medial border
- 5lateral border of the scapulaif you move from the inferior angle of the scapula along the superior & lateral bony line. This is the lateral border
- 6superior border of the scapulausing the medial border of the scapula and moving to the superior end we would find the superior angle. then we move medially across the superior border
- 7the claviclewalk your fingers across medially from the acromion
- 8the acromioclavicular jointthis joint line can be found on the lateral end of the clavicle where a small groove can be felt where it articulates with the acromion
- 9the sternoclavicular jointglide fingers medially across the shaft of the clavicle until you reach the sternal end. this is where the sternum articulates with the clavicle.
- 10the deltoid musclescontains anterior, middle and posterior fibres which are responsible for flexion, abduction & extension of the shoulder
- 11the subscapularis musclemain action is medial rotation and is part of the rotator cuff group of muscles
- 12the infraspinatus musclemain action is lateral rotation and is part of the rotator cuff group of muscle
- 13the supraspinatus muscleperforms first 15 degrees of abduction and is part of the rotator cuff group of muscles
- 14the teres minor musclemain action is lateral rotation & is part of the rotator cuff group of muscles. It can be posteriorly
- 15the glenohumeral jointthis is where the superior end of the humeral articulates with the glenoid fossa to form a ball and socket synovial joint giving a large range of movement
- 16measuring flexion & extensionfulcrum is 2 cm inferior to the acromion process
stationary arm runs parallel to the trunk - 17measuring abduction & adductionpatient is in supine
fulcrum is the humeral head
stationary arm is parallel to the trunk - 18measuring external rotationpatient in prone with arm at 90 degrees hanging off plinth
fulcrum placed on the olecranon process
stationary arm should be in line with the ulna styloid process
