Localized constrictive radial neuropathy in the absence of extrinsic compression: three cases
Abstract:
Three patients, one with bilateral disease, experienced spontaneous onset of radial nerve dysfunction. Each demonstrated significant motor paralysis and had surgical exploration 3 weeks to 3 months after symptoms were first noted. All three patients showed well-localized hourglass constrictions of the radial nerve that could not be attributed to extrinsic compression. Each subsequently required tendon transfers for a persistent radial nerve palsy. Each showed electrical evidence of late recovery, although this was incomplete in two out of three.

Assessment of the Cardiovascular System III: Palpation
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
