Rupture of the Adductor Muscles

Ruptures of the adductor longus can be partial or complete. Complete ruptures are usually located at the muscle’s insertion into the femur, but can also occur at its origin in the pubic bone. Partial ruptures usually occur in the muscle-tendon junction. A rupture of the adductor longus muscle can occur when the muscles of the adductor group are tense and overused, for example in soccer, when the ball and an opponent’s foot are kicked with the inside of the foot at the same time, or when a fast start, a gliding tackle, or a sudden turn is made.

Symptoms and diagnosis

– Sudden momentary stabbing pain in the groin region is experienced. When attempts are made to restart activity, the pain returns.
– Local bleeding can cause swelling and bruising, which may not appear until a few days after the injury has occurred.
– If the muscle cannot contract there is reason to suspect a total rupture.
– When the rupture is in the muscle-tendon junction a defect can be felt at the site of injury, and the muscle is also most tender there.
– A clinical examination should be performed when the muscle is in a relaxed state as well as in a contracted state with resistive tests.
– An X-ray should always be taken in athletes with groin pain. If a swelling is present, as in complete rupture, an MRI or ultrasound scan should be performed.

Treatment

The athlete should:
– treat the injury immediately with cooling, compression, bandaging, and elevation;
– rest initially (crutches may be helpful);
– avoid pain causing activities;
– start careful exercises and keep up range of motion.

The doctor may:
–A partial rupture will heal with scar tissue and a subsequent
inflammatory reaction after the acute stage;
– operate in cases of complete rupture;
– operate in cases of an incomplete rupture with chronic pain after unsuccessful conservative treatment;

Healing and complications

During the rehabilitation period the injured athlete should continue muscle training, cycling, light jogging, swimming and gradually increased conditioning. Not until the athlete is completely free from
discomfort when the injured muscle group is subjected to a load can regular training be resumed. Its intensity should at first be limited and then increased gradually. Matches and competition should be avoided
until recovery from the injury is complete, and the fully trained athlete has been tested under competition conditions.

Complete rupture of the adductor longus muscle can occur without great discomfort. It can, however, cause the affected individual to suspect the presence of a tumor, as the belly of the muscle increases in size owing to compensatory growth.
