Abstract
Hypermobility, or joint hyperlaxity, can result from inherited connective tissue disorders or from micro- or macrotrauma to a joint. The supraphysiologic motion of the hip joint results in capsuloligamentous damage, and these patients have a propensity to develop femoroacetabular impingement syndrome (FAIS) and labral injury. In this review, the recent literature evaluating the definitions, history, incidence, genetics, and histology of hypermobile disorders is investigated. We then review the clinical evaluation, natural history, and resulting instability for patients presenting with a hypermobile hip. Lastly, treatment options and outcomes will be highlighted.
Highlights
Hypermobility is becoming an increasingly recognized source of pain and instability of the hip joint [1,2,3,4]
While hypermobility with or without Ehlers– Danlos syndrome is relatively rare in the general population, it is of particular interest to hip arthroscopists due to the propensity of these patients to develop femoroacetabular impingement syndrome (FAIS) and labral injury [5]
Joint hypermobility can be an especially challenging comorbidity and has been associated with a variety of syndromes that exist on a varying spectrum including hip dysplasia, generalized joint hypermobility (GJH), hypermobile Ehlers–Danlos syndrome, and hypermobility spectrum disorder
