How to Prevent Ski Injury: Tips from Your Orthopedic Surgeon

January 16, 2021

By: Dr. ET Mejia As I returned from our annual family ski vacation, I wondered what my office waiting room would look like, usually packed with patients that stacked up while I was out of the office. It occurred to me that this is the time of the year when I see a flood of winter sports injuries superimposed on the typical seasonal basketball, wrestling, hockey, and other outdoor activities. While skiing in beautiful Big Sky, Montana, I couldn’t help but think of common themes that can contribute to a skiing injury. Some of these injuries include knee ligament tears, meniscus tears, patella dislocations, shoulder dislocations, rotator cuff tears, shoulder separations, and clavicle fractures, among others. One common denominator is an obvious one: less-experienced skiers are more susceptible to a skiing injury. However, there are other contributing factors, such as level of fitness, snow conditions, equipment, etc. I decided to list a few items that can lead to a skiing injury and will hopefully raise awareness to winter enthusiasts as they flock to the ski slopes. I have experienced or witnessed most of these, so I am sure many of you can relate. These tips have nothing to do with skiing techniques, but with simple common sense. Fatigue: This plays a huge role in ski injuries, just as it doe

Etienne (“E.T.”) Mejia, MD Knee pain is one of the most common conditions prompting patients to present to my office. Although there are many causes of knee pain, many people have pain around the front of the knee, or what we call “patellofemoral pain.” The patella is the kneecap. It is a focal area of the extensor mechanism of the knee where many vital structures attach, such as the thigh muscles (the quads), patellar tendon, and the supporting shrouds on either side (retinacula), which function as checkreins to keep the patella centered. The patella glides on a groove on the femur, also known as the “thigh bone.” The patella provides the surrounding muscles a significant mechanical advantage to straighten the knee from a bent position, but also to prevent the knee from collapsing and folding over when weight is applied. It allows us to jump, land, squat, climb and descend stairs. It requires tremendous coordination with hip and ankle muscles for it to work in a chain effect in the lower extremity. Any deviation from the fine coordination in the lower extremity chain can lead to patellofemoral pain. Patients with Knee Pain

By: ET Mejia, MD Frozen shoulder is a common cause of shoulder pain. It is poorly understood, and unfortunately, it is often missed or misdiagnosed and treated inappropriately. The frozen shoulder is characterized by stiffness and loss of shoulder range of motion accompanied by progressive shoulder pain. Sometimes the pain can be quite debilitating and significantly affect function and even sleep. Another term for “frozen shoulder” is adhesive capsulitis, although I believe that arthrofibrosis is a better diagnosis. “Arthro” means joint, and “fibrosis” means scarring or contraction. There are 2 main causes for shoulder stiffness and loss of joint motion: the frozen shoulder and an arthritic shoulder. The distinction is easily made by a simple x-ray. The frozen shoulder looks normal on x-ray, but the arthritic shoulder shows deformities, spurs and loss of normal joint space. The treatments are quite different for either condition, so it is important to get it right. Frozen shoulder commonly presents after a minor event or “tweak” that creates a smoldering discomfort and progressive motion loss, but it can also be a result of a significant shoulder injury, a fracture, or after surgery. Prolonged immobilization can predispose to frozen shoulder, although only some people get it and o

Colleen Dreher is spending the summer of 2020 enjoying the “Lake Life” with her family. The CEO of Dreher Collision Centers steps from the dock into the hull of her boat with ease, hugging two of her 12 grandchildren as she takes a seat next to them. This would not have been possible last summer. While traveling in Chicago eighteen months ago, the active business owner fell out of a pothole, damaging both of her shoulders. The injury was the final blow after years of aggravation from playing golf and hanging from the monkey-bars with her grandchildren. “I had a torn rotator cuff and there was atrophy of the muscle,” says Colleen. “It was difficult to drive to our service locations, which are located about an hour apart. I wasn’t the high-energy leader I wanted to be. It was impacting the relationships I had with my employees and my family.” She had shoulder surgery with another provider after her injury. When her pain persisted, she was told there was nothing more that could be done. She sought a second opinion, which was met with the same conclusion. After struggling through the winter of 2019, Colleen asked her nurse and best friend for advice. They both referred her to the
