The key to preventing injury is to maintain good strength, muscle balance and flexibility. Here are a few tips that you may find valuable:
- Warm-up before doing exercises, playing sports, or participating in any vigorous activities
- Participate in a conditioning program to build muscle strength
- Develop a daily ritual of stretching exercises
- Listen to your body: never run if you experience pain in the foot, ankle or knee, or you feel fatigued
- Pay attention to walking, running or working surfaces
- Wear protective equipment appropriate for the sport or activity that you’re engaged in
- Replace your athletic shoes as soon as the tread or heel wears out
- Be sure that all of your shoes fit properly
- Repetitive motion injuries can be avoided through rest breaks, exercise, proper posture, correct technique, use of protective equipment, and properly designed working environments.
A strain occurs when a muscle is stretched or torn. A sprain occurs when a ligament is stretched or torn.
Strains are often the result of overuse or improper use of a muscle, while sprains typically occur when a joint is subjected to excessive force or unnatural movements (e.g., sudden twists, turns, or stops). Sprains can be categorized by degree of severity:
- A first-degree sprain stretches the ligament but does not tear it. Symptoms include mild pain with normal movement.
- A second-degree sprain is characterized by a partially torn ligament, significant pain and swelling, restricted movement, and mild to moderate joint instability.
- X-rays are a type of radiation, and when they pass through the body, dense objects such as bone block the radiation and appear white on the X-ray film, while less dense tissues appear gray and are difficult to see. X-rays are typically used to diagnose and assess bone degeneration or disease, fractures and dislocations, infections, or tumors.
- Organs and tissues within the body contain magnetic properties. MRI, or magnetic resonance imaging, combines a powerful magnet with radio waves (instead of X-rays) and a computer to manipulate these magnetic elements and create highly detailed images of structures in the body. Images are viewed as cross sections or “slices” of the body part being scanned. There is no radiation involved as there is with X-rays. MRI scans are frequently used to diagnose bone and joint problems.
- A computed tomography (CT) scan (also known as CAT scan) is similar to an MRI in the detail and quality of image it produces, yet the CT scan is actually a sophisticated, powerful X-ray that takes 360-degree pictures of internal organs, the spine, and vertebrae. By combining X-rays and a computer, a CT scan, like an MRI, produces cross-sectional views of the body part being scanned. In many cases, a contrast dye is injected into the blood to make the structures more visible. CT scans show the bones of the spine much better than MRI, so they are more useful in diagnosing conditions affecting the vertebrae and other bones of the spine.
The Achilles tendon is the largest tendon in the body. It connects the muscles in the lower leg (calf) to the heel bone. With every movement of the foot, the Achilles tendon stretches and tightens. Because it is under so much stress, it can partially or completely tear (rupture) from excess force or overuse. Ruptures usually occur about two inches above where the tendon attaches to the heel bone.
An Achilles tendon rupture is most common in middle-aged “weekend warriors” who are not conditioned for athletics and who neglect to properly warm up and stretch prior to exercise. Ruptures frequently occur from sudden movements that stress the calf muscles, such as jumping or quick stops; from overstretching; from vigorous exercise after a long period of inactivity; or from untreated Achilles tendinitis/tendinosis (overuse).
Stenosis refers to a narrowing of the spinal canal, usually in the lower back (lumbar) region. This narrowing is often a result of the normal degenerative aging process. It occurs as the disks of cartilage that separate the spine’s vertebrae lose water and the space between the vertebrae become smaller, causing friction between the bones. The loss of water in the disks makes them less flexible and unable to act as shock absorbers in the spine. Daily wear and tear on the spine becomes more significant without these shock absorbers.
As the disks degenerate, vertebrae may shift, causing the spinal canal to narrow. In some cases, the nerves that travel through the spinal column to the legs become squeezed. This can cause back and leg pain, and even leg weakness. Arthritis and falls also contribute to the narrowing of the spinal canal, compressing the nerves and nerve roots and causing pain and discomfort.
Degenerative disk disease is a general term applied to back pain that has lasted for more than three months. It is caused by degenerative changes in the intervertebral disks in the spine and can occur anywhere in the spine: low back (lumbar), mid-back (thoracic), or neck (cervical).
Under the age of 30, these disks are normally soft, and they act as cushions for the vertebrae. With age, the material in these lumbar disks becomes less flexible and the disks begin to erode, losing some of their height. As their thickness decreases, their ability to act as a cushion lessens. The less dense cushion now alters the position of the vertebrae and the ligaments that connect them. In some cases, the loss of density can even cause the vertebra to shift their positions. As the vertebrae shift and affect the other bones, the nerves can get caught or pinched and muscle spasms can occur.
Degenerative disk disease is primarily a result of the normal aging process, but it may also occur as a result of trauma, infection, or direct injury to the disk. Heredity and physical fitness may also play a part in the process.
Impingement syndrome is a common disorder of the shoulder that refers to an improper alignment of the bones and tissues in the upper arm. Inflammatory conditions such as tendinitis, bursitis, and arthritis are all closely related to impingement syndrome, as are tears to the rotator cuff tendons.
If the rotator cuff becomes inflamed from overuse or there is a bone deformity or spur on the end of the shoulder blade, then the space between the upper arm bone and tip of the shoulder blade is narrowed, causing the rotator cuff and its fluid-filled bursa to be squeezed or pinched. This impingement causes irritation and pain to the rotator cuff when the shoulder is raised.
There are four ligaments in the knee: the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial collateral ligament (MCL), and lateral collateral ligament (LCL). The ACL and PCL stabilize front-to-back knee movements, while the MCL and LCL stabilize side-to-side movements.
The ACL can be sprained or torn if the knee is straightened beyond its normal limits (hyperextended), twisted, or bent side-to-side. A sprained or torn ACL is common in sports and usually results from a hard stop or aggressive twisting of the knee. The PCL is the least common ligament to be injured.
The MCL is injured when a force is exerted on the outside of the knee, pushing it inward, while the LCL is injured by a force exerted on the inside of the knee that pushes it outward. This type of hit is frequent in contact sports like football or hockey.
A torn knee ligament is usually accompanied by feeling or hearing a pop in the knee at the time of injury, severe pain and swelling, and joint instability.
A stress fracture is a microscopic crack in a bone that occurs from overuse. Muscles normally absorb the shock of physical activities, but when they become too fatigued to do so, they transfer the stress to the bones which results in a hairline-sized fracture.
Stress fractures usually develop in the weightbearing bones of the feet and lower legs, often after a rapid increase in the duration or intensity of exercise or from wearing improper or worn out athletic shoes.
The spinal vertebrae are separated by flexible disks of shock absorbing cartilage. These disks are made of a supple outer layer with a soft jelly-like core (nucleus). If a disk is compressed, so that part of it intrudes into the spinal canal but the outer layer has not been ruptured, it may be referred to as a “bulging” disk. This condition may or may not be painful and is extremely common.
Herniated disks are often referred to as “slipped” or “ruptured” disks. When a disk herniates, the tissue located in the center (nucleus) of the disk is forced outward. Although the disk does not actually “slip,” strong pressure on the disk may force a fragment of the nucleus to rupture the outer layer of the disk.
If the disk fragment does not interfere with the spinal nerves, the injury is usually not painful. If the disk fragment moves into the spinal canal and presses against one or more of the spinal nerves, it can cause nerve impingement and pain.
If the injured disk is in the low back, it may produce pain, numbness, or weakness in the lower back, leg, or foot. If the injured disk is in the neck, it may produce pain, numbness, or weakness in the shoulder, arm, or hand.
When a physician has completed an orthopedic residency and/or fellowship training, the American Board of Orthopaedic Surgery offers a written test to become board eligible. If the written test is passed, the physician becomes “eligible” to take the oral test, after two years in practice. When the physician passes the oral exam, the physician becomes “board certified” and is considered a Diplomate of the American Board of Orthopaedic Surgery.
The intent of the certification process, as defined by the board members of the American Board of Medical Specialties, is to provide assurance to the public that a certified medical specialist has successfully completed an approved educational program and an evaluation, including an examination process designed to assess the knowledge, experience, and skills requisite to the provision of high quality patient care in that specialty.
