You Kick Like A Girl

Significant differences in knee alignment and muscle activation exist between men and women while kicking a soccer ball, according to a study published in the Journal of Bone and Joint Surgery. Data reveals that males activate certain hip and leg muscles more than females during the motion of the instep and side-foot kicks - the most common soccer kicks - which may help explain why female players are more than twice as likely as males to sustain an anterior cruciate ligament (ACL) injury.

Prior research shows that females are more prone to non-contact ACL injuries than males and though many theories exist, a direct cause for the disparity is unknown. "By analyzing the detailed motion of a soccer kick in progress, our goal was to home in on some of the differences between in the sexes and how they may relate to injury risk, " said orthopedic surgeon Robert H. Brophy, MD, study author and assistant professor of orthopedics, Washington University School of Medicine in St. Louis. "This study offers more information to help us better understand the differences between male and female athletes, particularly soccer players."

The study found that male players activate the hip flexors (inside of the hip) in their kicking leg and the hip abductors (outside of the hip) in their supporting leg more than females. "Since females have less activation of the hip abductors, their hips tend to collapse into adduction during the kick, which can increase the load on the knee joint in the supporting leg, and potentially put it at greater risk for injury, " Dr. Brophy said.

In 2008, the Centers for Disease Control and Prevention published a study that found a new training program called the Prevent Injury and Enhance Performance (PEP) program, was effective in reducing ACL injuries in female soccer players. Developed by the Santa Monica Orthopedic and Sports Medicine Research Foundation and supported by the American Academy of Orthopaedic Surgeons among other medical and athletic associations, PEP is an alternative warm up regimen that focuses on stretching, strengthening and improving balance and movements and can be conducted during regular practice time and without special equipment. "Programs focusing on strengthening and recruiting muscles around the hip may be an important part of programs designed to reduce a female athletes' risk of ACL injury, " said Dr. Brophy.

Carpal Tunnel Syndrome, Part 2

In the last post we discussed how CTS is diagnosed and nonsurgical treatment. Part two discusses the surgical treatment for carpal tunnel syndrome.

Surgical carpal tunnel release remains the standard of care for severe carpal tunnel syndrome or when conservative treatment modalities have failed. Unfortunately, there still seems to be a great deal of fear and misinformation surrounding carpal tunnel surgery. Today carpal tunnel surgery can be performed with local anesthesia, with the patient wide awake, eliminating the need for fasting or an I.V. Many patients who have local anesthesia will come to surgery alone and drive themselves to and from the surgery center. For those patients who are still anxious about being alert during surgery, oral and I.V. sedation can still be made available.

Mini-incision carpal tunnel surgery is performed with the patient lying flat on their back with a small tourniquet on their forearm to prevent bleeding during surgery. A small half inch incision is made at the base of the palm and through this incision the transverse carpal tunnel ligament is divided in half, essentially opening the roof of the carpal tunnel and removing the pressure on the median nerve. Once the ligament is divided, the incision is closed with only one or two stitches. The entire procedure usually takes only 10 to 15 minutes. Following surgery, a light, soft dressing is applied, with no splint, and is worn for four to five days. Once the dressing is removed, a simple band-aid can be used to cover the incision to protect the stitches. After surgery patients are encouraged to move their wrist and fingers frequently and use their hand as tolerated. Many patients return to work and normal activities the day after surgery, although a couple of days of rest and light duty are not uncommon. The stitches are removed 10-14 days after surgery and most patients have significant improvement of their symptoms by the time they are seen for the post-op appointment. Once the carpal tunnel is released, recurrence of carpal tunnel syndrome is rare.

Today both surgical and non-surgical treatment of carpal tunnel syndrome is relatively safe and simple. Surgical treatment has a very high rate of success and patient satisfaction with a low rate of complications and risk. Non-surgical treatments, while not a permanent cure, can provide significant relief of symptoms. If you are one of the millions affected with carpal tunnel syndrome, talk to your doctor about your options or get an opinion for a specialist.

Adult Repetitive Strain Disorders, Part Two

Post provided by Barbara Bergin, MD

In the last post we discussed what repetitive strain disorders are, why we get them, and what you can do about them. Today's post continues with getting back to what you love after getting better and how to prevent repetitive strain disorders.

Once I get well can I go back to doing things like I was before?

- Probably not. Most people get these disorders because they are somehow anatomically predisposed to getting them, or because they are not put together to participate in certain activities. Frankly, most human beings are not put together to perform certain sports activities on a regular or high intensity basis. Our joints just will not tolerate repetitive strain for extended periods of time. Sometimes it is just a matter of conditioning ourselves to participate; like building up to run or swim long distances. But most of the time we get repetitive strain disorders because we are just wearing out our parts. We must make permanent changes. Again, that can mean minor alterations of the way we do things around the house, but it can also mean changing the way we participate in a sport or even discontinuation of that sport. I'm sorry to say this, but it's true. Most of these repetitive strain disorders occur in people who are 40+. I just don't see them in twenty year olds. If you refer to an earlier post, "Having Peace with Your Pain, " you'll understand a little more about my thoughts on that subject.

- Treating these conditions is kind of like treating hypertension. If your doctor says you have to take an anti-hypertensive medication, do you think you can just take that for a short period of time and your hypertension is cured? Can you stop taking the pill? Will your hypertension come back? Are you ever truly cured of hypertension? No. Occasionally there are people who will make major lifestyle changes and can lower their blood pressure but most people have to continue taking the medications for the rest of their lives. This is the same with most of these repetitive strain disorders. They will come back if you go back to doing things exactly the way you were doing them before. If you make 90% of the modifications permanent, you might be able to continue to enjoying some of the activities which previously caused you pain! You can live with that!

How can I prevent repetitive strain disorders?

- Some of them might be unavoidable, but general principles can always be applied: maintain a healthy weight, exercise in moderation, avoid extremes of high impact and high intensity exercises as you age, and maintain flexibility. It's also important to recognize repetitive strain pain and address it early, either by seeing your orthopedic surgeon (that's me) or your primary care physician, or by making the modifications yourself. It's common for people to try to "work through" the pain, thinking that it's better to work it than rest it. This kind of approach to pain probably stems from the idea that you have to "work through" the conditioning pain of getting into a higher intensity exercise like running. The first time you run a half mile, it hurts; your lungs, your feet, your legs. But as you continue to run and run longer distances, it gets better. This is not the philosophy to take with the pain you experience in a tendon or joint as the result of a certain activity or after that activity. Learn to recognize the difference and address it. Rest it. Ice it. Take Aleve or Advil (if your doctor says it's okay). Then modify it!
