Sarah Gill's Clinical Anatomy Lectures Flashcards
Give the three functions of the upper limb
Protection
Action and dexterity
Mobility
What is the shoulder girdle?
Everything from the sternoclavicular joint to the acromion and onto the scapula to the humeral head and proximal humerus
Name the three joints in the shoulder girdle
Sternoclavicular
Acromioclavicular
Glenohumeral
Give an alternative name for the shoulder girdle
Pectoral girdle
Where does the biceps groove run?
Along the humerus.
In a patient of any size you should always be able to palpate which boney landmark in the shoulder girdle?
The lateral corner of the acromion process.
The radial head is the proximal/distal end of the radius
Proximal
the radial head articulates with the humerus/carpal bones
Humerus
The acromioclavicular joint is most likely to dislocate in which group of people?
Young people
People who play sport (particularly rugby)
Name the ligaments which try to prevent dislocation of the acromioclavicular joint
The coracoclavicular ligaments
Treatment of an acromioclavicular joint dislocation is always steroid injections and anaesthetic. True/false
False it is usually conservative.
Steroids and local anaesthetic may be considered if it is not healing
What two conditions can affect the acromioclavicular joint?
Dislocation
Osteoarthritis
Where does the trapezius muscle originate?
all of the spinous processes down to T12
Where does the trapezius muscle insert
Occiput
Spine of Scapula
Name the two different necks of the humerus
Anatomical and surgical neck
the anatomical/surgical neck of the humerus is more likely to fracture
Surgical
Fracture of the anatomical neck of the humerus is almost always/never pathological
Almost always
Why is the glenohumeral joint less stable than the hip joint?
The humeral head is less well captured by the glenoid process
It sacrifices stability for mobility
Which two boney landmarks does the capsule of the glenohumeral joint run between?
the greater tuberosity of the humerus and the coracoid process of the scapula.
Adhesive capsulitis is a stiffness of the glenohumeral joint capsule. True/false
True
Adhesive capsulitis is not related to injury or trauma. True/false
False it is often caused by injury
Adhesive capsulitis is treated by surgery. True/false
False - first line treatment is physiotherapy. Surgical debridement is an option if it doesn’t resolve with physio (little evidence supporting this)
The labrum is a bony protrusion which helps to better capture the humeral head in the glenoid process - true/false
False - its a soft tissue protrusion which helps to better capture the humeral head in the glenoid process
