Physiotherapy: The body’s healing process

The Body’s Healing Process

From the moment a bone breaks or a ligament tears, your body goes to work to repair the damage. Here’s what happens at each stage of the healing process:

At the moment of injury: Chemicals are released from damaged cells, triggering a process called inflammation. Blood vessels at the injury site become dilated; blood flow increases to carry nutrients to the site of tissue damage.

Within hours of injury: White blood cells (leukocytes) travel down the bloodstream to the injury site where they begin to tear down and remove damaged tissue, allowing other specialized cells to start developing scar tissue.

Within days of injury: Scar tissue is formed on the skin or inside the body. The amount of scarring may be proportional to the amount of swelling, inflammation, or bleeding within. In the next few weeks, the damaged area will regain a great deal of strength as scar tissue continues to form.

Within a month of injury: Scar tissue may start to shrink, bringing damaged, torn, or separated tissues back together. However, it may be several months or more before the injury is completely healed.

Who Should I See for My Injury?

Although severe injuries will need to be seen immediately in an emergency room, particularly if they occur on the weekend or after office hours, most sports injuries can be evaluated and, in many cases, treated by your primary health care provider.

Depending on your preference and the severity of your injury or the likelihood that your injury may cause ongoing, long-term problems, you may want to see, or have your primary health care professional refer you to, one of the following:
•An orthopaedic surgeon is a doctor specializing in the diagnosis and treatment of the musculoskeletal system, which includes bones, joints, ligaments, tendons, muscles, and nerves.
•A physical therapist/physiotherapist is a health care professional who can develop a rehabilitation program. Your primary care physician may refer you to a physical therapist after you begin to recover from your injury to help strengthen muscles and joints and prevent further injury.

How Are Sports Injuries Treated?

Although using the RICE technique described previously can be helpful for any sports injury, RICE is often just a starting point. Here are some other treatments your doctor or other health care provider may administer, recommend, or prescribe to help your injury heal.1

 

All medicines can have side effects. Some medicines and side effects are mentioned in this publication. Some side effects may be more severe than others. You should review the package insert that comes with your medicine and ask your health care provider or pharmacist if you have any questions about the possible side effects.

Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)

The moment you are injured, chemicals are released from damaged tissue cells. This triggers the first stage of healing: inflammation (see the box “The Body’s Healing Process”). Inflammation causes tissues to become swollen, tender, and painful. Although inflammation is needed for healing, it can actually slow the healing process if left unchecked.

To reduce inflammation and pain, doctors and other health care providers often recommend taking an over-the-counter (OTC) nonsteroidal anti-inflammatory drug (NSAID) such as aspirin, ibuprofen (Advil,2 Motrin IB, Nuprin), ketoprofen (Actron, Orudis KT), or naproxen sodium (Aleve). For more severe pain and inflammation, doctors may prescribe one of several dozen NSAIDs available in prescription strength.3

Immobilization

Immobilization is a common treatment for sports injuries that may be done immediately by a trainer or paramedic. Immobilization involves reducing movement in the area to prevent further damage. By enabling the blood supply to flow more directly to the injury (or the site of surgery to repair damage from an injury), immobilization reduces pain, swelling, and muscle spasm and helps the healing process begin. Following are some devices used for immobilization:
•Slings, to immobilize the upper body, including the arms and shoulders.
•Splints and casts, to support and protect injured bones and soft tissue. Casts can be made from plaster or fiberglass. Splints can be custom made or ready made. Standard splints come in a variety of shapes and sizes and have Velcro straps that make them easy to put on and take off or adjust. Splints generally offer less support and protection than a cast, and therefore may not always be a treatment option.
•Leg immobilizers, to keep the knee from bending after injury or surgery. Made from foam rubber covered with fabric, leg immobilizers enclose the entire leg, fastening with Velcro straps.

Surgery

In some cases, surgery is needed to repair torn connective tissues or to realign bones with compound fractures. The vast majority of sports injuries, however, do not require surgery.

Rehabilitation (Exercise)

A key part of rehabilitation from sports injuries is a graduated exercise program designed to return the injured body part to a normal level of function.

With most injuries, early mobilization—getting the part moving as soon as possible—will speed healing. Generally, early mobilization starts with gentle range-of-motion exercises and then moves on to stretching and strengthening exercise when you can without increasing pain. For example, if you have a sprained ankle, you may be able to work on range of motion for the first day or two after the sprain by gently tracing letters with your big toe. Once your range of motion is fairly good, you can start doing gentle stretching and strengthening exercises. When you are ready, weights may be added to your exercise routine to further strengthen the injured area. The key is to avoid movement that causes pain.

As damaged tissue heals, scar tissue forms, which shrinks and brings torn or separated tissues back together. As a result, the injury site becomes tight or stiff, and damaged tissues are at risk of reinjury. That’s why stretching and strengthening exercises are so important. You should continue to stretch the muscles daily and as the first part of your warm-up before exercising.

When planning your rehabilitation program with a health care professional, remember that progression is the key principle. Start with just a few exercises, do them often, and then gradually increase how much you do. A complete rehabilitation program should include exercises for flexibility, endurance, and strength; instruction in balance and proper body mechanics related to the sport; and a planned return to full participation.

Throughout the rehabilitation process, avoid painful activities and concentrate on those exercises that will improve function in the injured part. Don’t resume your sport until you are sure you can stretch the injured tissues without any pain, swelling, or restricted movement, and monitor any other symptoms. When you do return to your sport, start slowly and gradually build up to full participation.

Rest

Although it is important to get moving as soon as possible, you must also take time to rest following an injury. All injuries need time to heal; proper rest will help the process. Your health care professional can guide you regarding the proper balance between rest and rehabilitation.
