Happy easter quiz _Part 2: Microinstability of the hip
Did you think about instability of the hip joint?
No, because the hip joint is a stable ball and socket joint. How can this joint be instable, beside traumatic dislocation or subluxation?
Subtle anatomic abnormalities in the presence of repetitive hip joint rotation and axial loading as seen in sports such as gymnastics, ballet, football, golf, figure skating, tennis and baseball can lead to micorinstability of the hip (1,2). In addition, inherent ligamentous laxity and/or peri-articular muscular weakness may be a predisposing factor for microinstability of the hip.
Since a few years symptomatic hip micorinstability has gained more attention. It is now recognized as a potential cause of pain and disability in young patients (3).
The diagnosis of hip microinstability is based mainly on a thorough subjective and physical examination. In addition, radiographic examination may be used to confirm the hypothesis.
