Anteroposterior (left) and frog-leg lateral (right) radiographs of the right hip, made in 1993, ten years after the in-situ fixation.



Anteroposterior (left) and frog-leg lateral (right) radiographs of the right hip, made eleven years later, in 2004.



Figs. 2-A through 2-G A twenty-year-old man presented to our institution in 1996 with a one-year history of increasing pain in the right groin.



Anteroposterior (left) and frog-leg lateral (right) radiographs of the right hip, made eight years later, in 2004.



Photomicrograph of the cyst wall, showing membranous fibrous tissue with focal chondroid metaplasia (hematoxylin and eosin staining, ×10).



Intraoperative photograph, taken after arthroscopically assisted mini-open anterior decompression of the hip with débridement and bone-grafting of the cystic cavity.



Anteroposterior (left) and frog-leg lateral (right) radiographs of the right hip, made one year after cyst removal, grafting, and prophylactic stabilization with a dynamic hip screw.



Figs. 3-A, 3-B, and 3-C A forty-six-year-old woman presented to our institution in 2004 with a six-month history of right hip pain after prolonged sitting and activities requiring hip flexion.



Preoperative radial, proton-density-weighted, turbo-spin-echo, fat-suppressed magnetic resonance image of the right hip, made one year later, in 2005.



Anteroposterior (left) and frog-leg lateral (right) radiographs, made of the right hip in 2006, ten months after arthroscopically assisted mini-open anterior decompression, cyst resection, bone-
