A young adult presents with proximal weakness of upper limbs, features of facial palsy and winging of scapula. The most likely diagnosis is:
| A |
Facio-Scapulo-Humeral Dystrophy |
|
| B |
Limb-Girdle Dystrophy |
|
| C |
Scapuloperoneal Dystrophy |
|
| D |
Duchene Muscular Dystrophy |

Limb-Girdle Dystrophy |
|
| C |
Scapuloperoneal Dystrophy |
|
| D |
Duchene Muscular Dystrophy |
Answer is A (Facio-Scapulo-Humeral Dystrophy):
Weakness preferentially affecting the facial and shoulder girdle (proximal weakness of upper limb) together with winging of scapula in a young adult suggests a diagnosis of facio-scapulo-humeral dystrophy.
- Autosomal Dominant (Positive Family History(2)
- Abnormal gene 4q (4q35 deletion)
- Childhood to young adulthood (may be delayed to 5th decade)
- Mild 1st CPK (Normal Dystrophy)
Winging of scapula which muscle is affected
| A |
Teres minor |
|
| B |
Latissimus dorsi |
|
| C |
Subscapularis |
|
| D |
Serratus anterior |
Winging of scapula which muscle is affected
| A |
Teres minor |
|
| B |
Latissimus dorsi |
|
| C |
Subscapularis |
|
| D |
Serratus anterior |
Ans. is ‘d’ i.e., Serratus anterior
Winging of scapula
- In this condition the vertebral border of scapula becomes more prominent when patient tries to push against wall.
- It occurs in paralysis of the serratus anterior muscle in long thoracic nerve palsy.
Winging of scapula is due to which of these conditions?
| A |
Long thoracic nerve palsy |
|
| B |
Thoraco-dorsal nerve palsy |
|
| C |
Erb’s palsy |
|
| D |
Klumpke’s palsy |
