Thomas test Synonym: Hip flexion contracture test, Iliacus test, Iliopsoas test Fixed flexion deformity of the hip and anterior pelvic tilt leads to a compensatory hyperlordosis of the lumbar spine to restore the body’s center of gravity. Compensatory hyperlordosis can mask the fixed flexion deformity of hip. Thomas test: With…

Dermatomes : Mnemonic
Note: C1 doesn’t have a sensory branch For the purpose of making learning easier, we divide the remaining dermatomal segments into 4 groups which will be accompanied by analogies and mnemonics. C2-C4 These supply the “hooded cape” region. C2: hood region abutting the trigeminal distribution C3: upper neck C4: lower…

Nerve Conduction Study (NCS) and Electromyography (EMG) : Mnemonic Approach
Nerve Conduction Study (NCS) In the Nerve conduction study, assessment must be done for ABCDEFGH. Action potential Amplitude Measures the height of response in millivolts (mV) for motor nerve and microvolts (μV) for sensory nerve Indicates quantity of axons contributing to action potential Block of conduction CMAP on proximal stimulation…

Handtevy Method : Emergency Drug Dose by Age
To obtain the correct weight for each age, assign each finger a chronological odd number starting with 1, representing the age in years. Now, using the same fingers, count in the multiples of 5, starting with 10 to obtain the corresponding ideal body weight in kilograms. For the even ages,…

Renal Counter-Current Mechanism Made Easy
The term counter-current means flow in opposite direction. The renal counter-current mechanism comprises of: Flow of filtrate in opposite direction in nephron loop (down the descending limb and up the ascending limb of LOH or Loop of Henle) – that functions as a counter-current multiplier Flow of blood in opposite…

Oxygen Hemoglobin Dissociation Curve : Mnemonic
The oxygen hemoglobin dissociation curve is sigmoidal in shape because the binding of 1st oxygen molecule is difficult, however once bound, they facilitate the binding of subsequent molecules until the saturation is reached (plateau). This is called the allosteric interaction (cooperativity). Lets come to the mnemonics now. The curve can…
