Abstract:
The cases of 11 patients with the syndrome of thrombocytopenia and absent radius (TAR syndrome) who presented at two institutions between 1970 and 1996 were reviewed. Knee deformities have been well documented in thrombocytopenia and absent radius syndrome, but an inordinate frequency of other lower extremity problems needing orthopaedic attention was seen. Five of the 11 patients with thrombocytopenia and absent radius syndrome studied had knee deformities, but seven of the 11 had 11 other lower extremity deformities. This article documents all of the lower extremity problems seen in the seven patients with thrombocytopenia and absent radius syndrome with anomalies other than those of the knee.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

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...
