Hip Pain in Dancers, Just a Pulled Muscle?

The hip joint is a ball and socket joint and lined with a thin layer of hyaline cartilage. The rim of the hip joint is lined with a special ridge of soft tissue called the labrum that adds stability to the hip joint. Groin sprain and strain are not uncommon in dancers after performing extreme hip movements. While many of these soft-tissue injuries tend to settle over time, there are cases in which the pain may persist and limit the dancing activities. The possible cause for such pain includes underlying labral tear, cartilage lesions or Femoroacetabular Impingement (FAI), also known as hip impingement.
Hip impingement occurs when something prevents the smooth, normal free movement of the ball-and-socket joint. This condition can occur at any age but more frequently in adolescents and young adults. Repetitive grinding of the femoral neck onto the rim of the acetabulum can lead to cartilage and labral failure.
There are two types of hip impingements:
The diagnosis can be made by reviewing the patient’s health history and a physical examination. Other tests may include:
Radiography (X-rays) of the hip
Magnetic Resonance Imaging (MRI) which visualizes the soft tissue cartilage and labrum Computed Tomography (CT) scan
Some patients with mild symptoms can manage with non-operative therapy:
Reduce the level of physical activity
Non-steroids anti-inflammatory (NSAIDs)
In some cases, surgery may be needed to manage the underlying problem. The recent arthroscopic technique in hip surgery has gained a favorable outcome in FAI.
