Hypermobile Hip Syndrome

Hypermobile hip syndrome is defined as the triad of symptoms (pain and instability), physical examination findings (confirms the subjective history), and imaging findings (corroborates the subjective and objective examination) consistent with hip instability, manifest along a spectrum from microinstability to dislocation. Soft tissue (capsule and labrum) and osseous (coverage, rotational profiles) structures may contribute. Imaging may reveal unique findings, include an anterior or anterolateral hypermobile hip crevasse. Surgical management must ensure anatomical corrections of pathomorphology, labral preservation, and routine complete capsular closure, with variable degrees of plication and shift able to be achieved with modern instrumentation. Postoperative care with physical therapy and medical management optimizes outcomes.
