Excellent! I have all the diagrams and content needed. Here is a thorough, well-organized answer:
Anatomy Viva & Osteology Practical - Complete Preparation Guide
(Source: Gray's Anatomy for Students)
PART 1: VIVA TIPS - How to Excel
Before the Exam
- Revise using the ABCN formula for every structure: Artery, Borders/relations, Clinical points, Nerve supply
- For each bone, know: name, type, side, identify by a unique feature, attachments, articulations, and clinical relevance
- Practice describing bones out loud - saying it aloud is very different from just reading
At the Viva Table
Bone identification - do this every time:
- Pick it up correctly - hold it confidently
- State the name - "This is the right femur"
- State how you identified it - give 2-3 distinctive features
- Side determination - explain your reasoning (e.g., "the head is medial, the greater trochanter is lateral")
- Orient it anatomically - hold it in the correct position
When asked about attachments:
- Go region by region (proximal to distal)
- Name the muscle + its action
- The examiner loves when you link the muscle action to the attachment site
Clinically impress the examiner:
- Always connect fractures to nerves at risk (e.g., surgical neck of humerus - axillary nerve)
- Mention "clinically important" features unprompted
Communication tips:
- If you don't know, say "I'm not sure of the exact detail, but I know that..." - never stay completely silent
- Use proper anatomical terms: "superior", "medial", "proximal" - not "up", "inside", "top"
- Think step by step out loud - examiners give credit for reasoning
PART 2: KEY BONES FOR OSTEOLOGY
HUMERUS (Upper Limb - Most Common Viva Bone)
How to identify the side: Head points medially + greater tubercle is lateral
Rotator Cuff Attachments on Greater Tubercle (remember: SIT on the greater - Supraspinatus, Infraspinatus, Teres minor):
| Facet | Muscle |
|---|---|
| Superior facet | Supraspinatus |
| Middle facet | Infraspinatus |
| Inferior facet | Teres minor |
Lesser Tubercle: Subscapularis (the 4th rotator cuff muscle - the only one on the anterior/lesser side)
Intertubercular (Bicipital) Groove:
- Lateral lip - Pectoralis major
- Floor - Latissimus dorsi
- Medial lip - Teres major
- Tendon of long head of biceps passes through the groove
Shaft landmarks:
- Deltoid tuberosity (lateral, midshaft) - attachment for deltoid
- Coracobrachialis attaches on the medial surface at roughly the same level
Surgical neck - radial nerve runs in the spiral groove; axillary nerve and posterior circumflex humeral artery pass posteriorly to the surgical neck - fracture here can injure the axillary nerve (test deltoid and skin over lateral shoulder)
(Gray's Anatomy for Students, p. 822-823)
SCAPULA (Frequently Asked)
Key features to know:
- Spine divides posterior surface into supraspinous fossa (supraspinatus) and infraspinous fossa (infraspinatus)
- Acromion - articulates with clavicle; arches over glenohumeral joint
- Coracoid process - hook-like, projects anterolaterally; attachment for short head of biceps, coracobrachialis, pectoralis minor
- Suprascapular notch - suprascapular nerve passes through (but artery passes over - "lawyers pass under the bridge, soldiers pass over")
- Subscapular fossa (anterior/costal surface) - subscapularis muscle
- Glenoid cavity - articulates with head of humerus
- Supraglenoid tubercle - long head of biceps origin
- Infraglenoid tubercle - long head of triceps origin
- Lateral border is thick and strong (muscle attachment); medial border is thin and sharp
(Gray's Anatomy for Students, p. 821-822)
FEMUR (Lower Limb - Most Common Viva Bone)
How to identify the side: Head is medial + greater trochanter is lateral; lesser trochanter is posteromedial (visible from behind)
Neck angle: ~125 degrees to the shaft (abnormal = coxa vara/valga)
Greater Trochanter attachments:
- Gluteus medius - posterolateral ridge
- Gluteus minimus - anterolateral ridge
- Obturator externus - oval depression in trochanteric fossa
- Obturator internus + gemelli - medial aspect, just above trochanteric fossa
- Piriformis - just above and behind obturator internus
Lesser Trochanter: Iliopsoas (psoas major + iliacus) - the prime hip flexor
Intertrochanteric line (anterior surface) - iliofemoral ligament (strongest ligament in the body) attaches here
Intertrochanteric crest (posterior surface) - quadratus femoris attaches to the quadrate tubercle on this crest
Clinical: Femoral neck fractures can disrupt blood supply to the femoral head (mainly from medial circumflex femoral artery) causing avascular necrosis - a classic viva question!
(Gray's Anatomy for Students, p. 657)
PART 3: HIGH-YIELD OSTEOLOGY VIVA Q&A
| Question | Key Answer |
|---|---|
| Which nerve is at risk in surgical neck of humerus fracture? | Axillary nerve |
| Which nerve is at risk in mid-shaft humerus fracture? | Radial nerve (in spiral groove) |
| What passes through the bicipital groove? | Tendon of long head of biceps |
| Which is the weakest part of the humerus? | Surgical neck |
| What attaches to lesser trochanter? | Iliopsoas (psoas major + iliacus) |
| What is the angle of femoral neck? | ~125 degrees |
| What passes through suprascapular notch? | Suprascapular nerve (not artery) |
| Which tubercle is for long head of biceps origin? | Supraglenoid tubercle |
| Which tubercle is for long head of triceps origin? | Infraglenoid tubercle |
| Blood supply to femoral head (main)? | Medial circumflex femoral artery |
PART 4: QUICK REVISION STRATEGY FOR TUESDAY
- Sunday (today): Upper limb bones - clavicle, scapula, humerus, radius, ulna
- Monday: Lower limb bones - hip bone (ilium, ischium, pubis), femur, tibia, fibula; revise nerve injuries
- Monday night: Do 1 full practice run - pick up each bone, state name, side, 3 features, and 3 muscle attachments out loud
The golden rule: Every examiner asks "What is the clinical importance?" after you identify a feature. Have a clinical point ready for every major landmark.
Good luck on Tuesday - you've got this!
