Thigh injuries

Injuries to the thigh are relatively common in athletes. Muscle injuries predominate, such as contusion injuries which often occur in soccer. Muscle strains are common in explosive sports such as sprinting, involving especially the hamstring muscles. Other causes of pain are stress fracture, compartment syndromes, and referred pain. Vague pain in the thigh may be […]

Lateral Hip Discomfort Trochanteritis (Inflammation and Calcification of the greater Trochanter)

Some of the large muscle groups of the buttocks have their attachments to the greater trochanter of the femur in the upper, outer (lateral) part of the thigh. An irritant inflammatory condition can be initiated in the muscle attachment of the gluteal muscles in, for example, crosscountry runners and orienteers.

Symptoms and diagnosis

– Pain […]

Hernia

Inguinal and femoral hernias are not uncommon and can be symptomatic producing radiating pain diffusely in the groin area. In athletes with persistent pain, ‘sports hernia’ can be a cause of problems: this is a syndrome of weakness of the posterior inguinal wall causing chronic groin pain, but without a clinically recognizable hernia.

Osteitis Pubis

Some athletes are afflicted by pain located in the anterior aspect of the pubic bone. Inflammation of the pubic bone occurs in soccer, ice hockey and American football players, as well as in long-distance runners and weightlifters. There is usually no trauma involved, instead there is a gradual onset with pain centrally localized in the […]

Rupture of the Upper part of the Rectus Femoris Muscle-Tendon Unit

Pain in the groin can be caused by a rupture in the origin or the upper third of the rectus femoris muscletendon junction. This rupture is usually partial, but complete rupture may occur. The rupture can occur during shooting and tackling in football and also during fast acceleration in general.

Symptoms and diagnosis

– During […]

Overuse Injury of the Iliopsoas Muscle

The iliopsoas muscle is by far the strongest flexor of the hip joint. It arises from the lumbar vertebrae (psoas) and the inner aspect of the hip bone (iliac muscle) and is inserted into the lesser trochanter (the inner aspect of the femoral shaft). Load on the muscle essentially means load on the insertion. Overuse […]

Groin Injuries

Overuse of the adductor muscle-tendon unit

The muscles that draw the leg inwards (adduct at the hip joint) are primarily the adductor longus, the adductor magnus, the adductor brevis, and the pectineus muscles. The gracilis muscle and the lower fibers of the gluteus maximus also work as adductors. However, it is usually the adductor […]

Groin and Thigh

Groin pain

Groin pain in athletes is a common problem: it occurs in soccer in 5–13% of injuries in men and in 4–5% of injuries in women. It is one of the most difficult problems in sports medicine. A groin injury may be acute but if often leads to chronic pain with diffuse symptoms that […]

Symphysitis

SYMPTOMS

There is gradual onset of diffuse or localised exercise-induced pain in both the groin and around the symphysis. The symptoms are often vague and secondary muscular symptoms are very common, misleading the examiner.

AETIOLOGY

This condition is thought to be a stress reaction from excessive jumping or running exercises but the exact […]

Stress Fracture of the Pelvis

SYMPTOMS

There is gradual onset of diffuse or localised exercise-induced pain in the groin or pelvic area in a young anorexic athlete (often a female long-distance runner) or in elderly athletes with osteoporosis.

AETIOLOGY

Stress reaction from excessive jumping or running exercises in fragile athletes. Stress fractures in the flat bones such as […]
