An old brick has a natural cavity on one side, providing a cool daytime slug hiding place. Look under any you have around the garden and dispose of the slugs found sheltering. Purposely position a few to create slug shelters, and check daily. A brick also makes a handy squishing implement.
Q Angle of the Knee. The Q angle of the knee is a measurement of the angle between the quadriceps muscles and the patella tendon and provides useful information about the alignment of the knee joint.
Problems with Measuring 'Q' Angle. Problem with using the Q angle as a measure of the lateral pull on the patella is that the line between the ASIS and the midpatella is only an estimate of the line of pull of the quadriceps and does not necessarily reflect the actual line of pull in the patient being examined.
