Upper limb bones- shoulder/elbow Flashcards
1
Q
Scapula landmarks
A
• Borders = medial, lateral
• Angles = inf and sup
• Fossae = supraspinous, infraspinous, subscapular, glenoid
• Processes = coracoid, acromion, spine
* note labrum = connective tissue deepening glenoid fossa
2
Q
Ligaments of shoulder complex
A
- Sternoclavicular lig
- Coracoclavicular lig
- Acromioclavicular lig
- Coracoacromial lig
3
Q
Glenohumeral ligaments
A
- Superior GH lig
- Middle GH lig
- Inferior GH lig- key stabiliser anteriorly, attaches to labrum and inf. margin of neck of humerous
4
Q
Proximal humerus anterior view
A
- Head
- Anatomical neck
- Greater tubercle- increases mechanical advantage of muscles attaching here
- Lesser tubercle
- Intertubercular groove
- Surgical neck- lower than anat neck
- Deltoid tuberosity- halfway down
- Shaft
5
Q
Proximal humerus posterior view
A
- Head
- Anatomical neck
- Surgical neck
- Radial groove
6
Q
Distal humerus
A
- Lateral epicondyle
- Capitulum (lateral to trochlea)- contributes humeroradial
- Medial epicondyle
- Trochlea (medial to captiulum)- contributes humeroulnar
- Olecranon fossa
- Coronoid fossa
- Radial fossa
7
Q
Ulna
A
- Olecranon (proximal)
- Trochlear notch (medial to radial notch)
- Radial notch (lateral to trochlear notch)
- Ulnar tuberosity
- Shaft
- Head (distal)
8
Q
Radius
A
- Head (proximal)
- Radial tuberosity
- Shaft
- Styloid process
9
Q
Elbow ligaments
A
- Lateral collateral (radial)
- Medial collateral (ulna)
- Annular ligament- encircles head of radius, prevents inferior dislocation
