Coxa saltans misdiagnosed as functional gait disorder: Two cases

Two unrelated young girls were evaluated for a gait suspected to be functional (video). Hip movements during ambulation were excessive despite normal tone, strength, sensation, and muscle stretch reflexes. Ascertainment of joint hypermobility led to the diagnosis of Ehlers-Danlos syndrome in both. Coxa saltans, also known as “dancer’s hip” or “snapping hip,” may develop among young athletes with clicking joints due to connective tissue disorders.1 The gluteus maximum tendon, iliotibial band, or tensor fascia lata slide back and forth across the greater trochanter during flexion–extension movements in external coxa saltans (figure). Case 1 required bilateral iliotibial band lengthening surgery.2
