The Blue Bulge Sign. Arthroscopic Tips to Identify and Decompress an Atypical Hip Paralabral Cyst

Abstract

We present the case of a 49-year-old woman who developed gradual left hip pain, both mechanically and at rest. She was subsequently evaluated for the presence of a large, atypical, anterior inferomedial paralabral cyst in addition to the conventional features of hip femoroacetabular impingement. Her persistent symptoms were successfully treated via hip arthroscopy. Technical details for identifying and locating this paralabral cyst as well as decompression of its contents are discussed in greater detail in this article, as are intraoperative arthroscopy images.
