A thigh strain is an injury caused by damage to a muscle or tendon in the thigh. The damage can take the form of the muscle being stretched beyond its limit (with no tearing of the muscle or tendon). These are commonly referred to as pulled thigh muscles. In other cases, one or more of the thigh muscles or tendons may be partially torn or even completely severed.
Typical symptoms of a thigh strain are sharp initial pain in the area of the damaged muscle followed by continued pain and swelling. The injured individual may also experience contusions over the injured muscle or tendon and may have difficulty placing body weight on the injured leg.
In most cases, thigh strains are treatable at home by resting the injured thigh and keeping weight off it for a period. Ice or a cold compress can also help to ease pain and swelling. If the thigh strain is in the most severe category (a complete severing of the muscle or tendon), surgerir the damage and reattach the muscle or tendon.
There are three muscle groups in the thigh that may be involved in a thigh strain:
Both hamstring and quadricep strains are covered in detail on other pages of this site and these pages are linked to above. Hamstring, quadriceps and adductor strains tend to be more common than strains of other muscles. This is partially because these muscles cross both the hip and knee joints. As a result, they may be subject to greater forces than other muscle groups that cross only one joint.
As with most other types of muscle injuries, thigh strains can be graded as I to III depending on their severity.
Thigh strains are common among soccer and hockey players. They are also frequently seen in football, basketball, figure skating, tennis, baseball and a few other sports.
These injuries are probably most commonly experienced when trying to abruptly change direction. Another common cause is a sudden attempt to accelerate while sprinting. Another, albeit less common, cause is an attempt to jump that puts too much stress on the adductor tendon.
Risk factors for these injuries include the following:
The most typical symptom of a thigh strain (whether it involves the adductor, hamstring or quadriceps muscles) is a sudden onset of severe pain during one of the activities described above (changing direction, sprinting or jumping). It is also possible for the pain of this injury to come on gradually.
The pain of an adductor strain is most commonly felt in the groin or inner thigh regions. A hamstring strain will be felt at the back of the thigh while a quadriceps strain will cause pain at the back of the thigh.
Other possible signs of a thigh strain are:
If you are experiencing these symptoms, we suggest visiting a healthcare professional for medical advice.
Thigh strains, whether involving the hamstring, quadriceps or adductor muscles, are usually treatable conservatively using the R.I.C.E. protocol.
A doctor will usually advise the patient to:
The patient may also be advised to work with a therapist on a program of physical therapy exercises to strengthen the thigh and groin muscles.
If the thigh strain is a grade III injury (i.e. involving a completely severed muscle or tendon), the conservative treatment described above is unlikely to be adequate. Instead, a surgeon will need to operate to repair the damage and reattach the severed tendon or muscle.
