It's a well-known fact that women athletes injure the anterior cruciate ligament (ACL) of their knees more often than men. Many explanations have been suggested. Perhaps the training of men and women is different enough to increase risk for ACL injury in women. There are gender differences in hormone levels, knee structure, hip width, and the angles at which muscles attach around the knee. However, no single cause or combination of factors has been proven. One of the functions of the ACL is to keep the larger bone in the lower leg (tibia) from sliding forward of the upper leg bone (femur). This movement of the tibia at the knee is called tibial translation . The ACL keeps forward tibial translation in check. Contracting the muscles around the knee increases the stiffness of the knee. This also reduces forward tibial motion and offers additional protection to the ACL. Since scientists haven't been able to pin gender differences on anything within the joint, they decided to test the muscle...
Full Question: Somewhere I read that upper thoracic scoliosis can cause migraines that begin with stiffness in neck and travel up one side of the head. Have you heard of this? Katherine Answer: Dear Katherine; Cause, no. Trigger, absolutely. Any disequilibrium of spinal structures can contribute to Migraines in a given individual; I'd expect the headache to begin at the base of the neck or between the shoulder blades.

About once or
twice a month, I see a young male in his late teens or early 20s who come to me
to evaluate a bump or lesion on his penis. Interestingly, many of these men
have sought evaluation before and STILL don't know what they have.
Here are the
most common causes of this symptom:
grouped lesions on the penis that are painful? Think about genital herpes as the cause. These lesions can also occur on the buttocks or anal area. The
initial outbreak may be associated with fever. Herpes is the most common STD in
and most genital lesions in men are herpes.
Have a bump
that looks like a wart or has a cauliflower appearance? You may have genital
warts. Warts are caused by certain strains of human papillomavirus --
different ones than those that cause cervical cancer in women. In most cases,
the warts do not cause symptoms, but occasionally they can burn, itch or be
tender. They can also produce a discharge. The lesions may be tan, pink or
