Hip injuries are common even amongst the most active. This week Kirstie Tyson looks into how hip impingement affects dancers and their ability to perform their best.

FAI diagnosis.

Hip impingement in dancers can be a source of stiffness, muscle pain and decreased performance. If left untreated, it can lead to the end of a sporting or dance career.

This is especially true for dancers, who often present for assessment months, or years, after the initial onset of pain.

The most common form of hip impingement injury, is a diagnosis of Femoroacetabular impingement (FAI).

FAI is the change in hip morphology around the ‘ball and socket’ joint. This impingement generally manifests in stiffness, pain and muscle weakness or atrophy.

There are three main types of FAI:

  • Cam Lesions refer to a change in morphology of the femoral head (the highest part of the thigh bone). This leads to the development of a bump around the femoral neck, which means the femoral head bone can no longer rotate smoothly within the joint.
  • Pincer Lesions refer to when extra bone (spurring) is seen extending over the acetabular rim. The acetabular rim is the socket that meets the femoral head in the hip joint.
  • Combined Lesions refer to a combination of both Cam and Pincer Lesions seen in the hip joint.

FAI is considered to be a major contributor for a variety of hip pathologies. However, this injury exhibits itself differently in dancers vs. general athletes. This may be due to the increased range of motion and stress placed on the joint at high range.

Symptoms of hip impingement can include:

  • Deep aching pain in the anterior groin.
  • Night pain.
  • Mechanical symptoms – clicking, catching and giving way.

The difference with dancers.

Dancers tend to experience symptoms of FAI, despite normal hip morphology. There is also increased incidences of superior and postero-superior labral tears or impingement. This contrasts with the general population, who usually develop tears in the anterior or antero-superior labrum.

The injuries incurred by dancers are both distinct and more common – with impingement and labral tears in dancers being as high as 23.5%, compared to only 5-6% of the general population experiencing these injuries.

The major causes of labral injuries are trauma, FAI, capsular laxity, hip dysplasia and degeneration. It has been suggested that up to 85% of dancers with labral tears also exhibit concomitant cartilage abnormalities.

Charbonnier et al (2009) found that during dance positions such as, grand écart facial, grand écart latéral, développé à la seconde and grand plié, a large amount of stress is placed on the hips of the dancer.

They also reported that the highest frequency of hip impingement occurs in grand écart latéral in the front (flexed) leg, whilst développé à la seconde, grand écart facial and grand pliés have an increased frequency of subluxation of the hip joint. As a result, it is generally advised that repetition of these movements is restricted.

We’re here to help.

Treatment for hip impingement generally includes manual therapy to improve joint range of motion and reduce muscular tension.

Treatment also includes retraining of the muscles which have shown signs of weakness or atrophy, and technique analysis and correction under advice from a dance teacher or dance company director.
