Rotator Cuff Muscles

 

Remember them with the mnemonic SITS (Supraspinatus, Infraspinatus, Teres Minor, Subscapularis).
Also remember the "Empty can supraspinatus test" used to evaluate this muscle asking the patient to abduct his/her arm to 90 degrees and flex the arm from that position 30 degrees (horizontally) with thumbs pointing to the floor, then apply downward force to his/her arms. This maneuver will elicit pain and weakness on the affected side due to impingement of the supraspinatus tendon (the most commonly affected structure in Rotator cuff Sd) between the acromion and the head of the humerus.

Nerves and Muscles responsible for abduction of the arm:

• Initiates arm abduction (initial 10 degrees) → Supraspinatus muscle <Suprascapular nerve>
• Abduct arm beyond 10 degrees → Deltoid muscle <Axillary nerve>
• Raise arm above horizontal → Serratus ant & Trapezius muscles <Long thoracic & Spinal acc nerves>

Colle's Fracture

Here another example of Colle's fracture.

Urinary System

Cholinomimetics

Some Cholinergic agonists and their functions

Neostigmine → Myasthenia Gravis, PO & neurogenic ileus and urinary retention, Reversal of NM junction blockage

Pyridostigmine → Myasthenia Gravis (long acting)

Edrophonium → Myasthenia Gravis Diagnosis (extremely short acting)

Physostigmine → Glaucoma (crosses BBB), and atropine overdose

Echothiopate → Glaucoma

Galantamine/ Donepezil / Rivastigmine/ Tacrine → Alzheimer's

Anterior Shoulder dislocation

Structures @ risk for injury with an anterior shoulder dislocation?

• Axillary nerve and posterior circumflex artery   (Runs together)
• Supraspinatous tendon
• Anterior glenohumeral ligaments and glenoid labrum separation from the articular surface of the anterior glenoid neck (AKA Bankhart lesion)
• Posterolateral humeral head defect (due to abrasion against the anterior rim of the glenoid) (AKA Hill-Sack lesion)

Craniopharyngioma

MRI in lateral view. Large cystic craniopharyngioma in an adult with severe hormonal deficiency, drowsiness and visual deficit. The yellow arrow points to the small solid part, the red to the large cyst.
Remember Craniopharyngiomas typically have 3 components SOLID, CYSTIC, and CALCIFIED
