Garrett Jr MD PhD Abstract Muscle strain is a very common injury. Muscles that are frequently involved cross two joints act mainly in an eccentric fashion and contain a high percentage of fast-twitch fibers. Muscle strain usually causes acute pain and occurs during strenuous activity. In most cases the diagnosis can be made on the basis of the history and physical examination. Magnetic resonance imaging is recommended only when radiologic evaluation is necessary for diagnosis. Initial treatment consists of rest ice compression and nonsteroidal antiinflammatory drug therapy. As pain and swelling subside physical therapy should be initiated to restore flexibility and strength. Avoiding excessive fatigue and performing adequate warm-up before intense exercise may help to prevent muscle strain injury. The long-term outcome after muscle strain injury is usually excellent and complications are few. J Am Acad Orthop Surg 1999 7 262-269 Muscle injuries are very common in persons who participate in sports. In addition to the inconvenience and discomfort associated with such injuries they also have a significant economic impact if the work-related costs are considered. The spectrum of these injuries is wide and includes contusion laceration delayed-onset muscle soreness and muscle strain. Contusion is caused by a direct blow to the muscle and is treated with a three-phase treatment program involving 1 a short period of immobilization with the muscle in a lengthened position 2 passive and active range-of-motion exercises and 3 strengthening. Laceration is uncommon and is seen more often after trauma than after sports accidents. Treatment includes thorough irrigation and debridement followed by suture repair of the fascia if possible. Completely lacerated muscles recover approximately 50 of their strength and 80 of their ability to shorten. Delayed-onset muscle soreness is defined as muscular pain
