Abstract:
Ischiofemoral impingement syndrome (IFIS) is an unusual cause of hip pain. Certain strenuous sports can cause this impingement, such as dancing. We report the case of an 11-year-old ballet dancer with bilateral IFIS secondary to overtraining and hypertrophy of the quadratus femoris. This syndrome is frequently evoked in the field of orthopedics following hip replacement. Bilateral IFIS is rare and should be sought in the context of an intense sport such as dance when any other cause has been eliminated.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
