JBJS Case Connector 12(4):e22.00401, October-December 2022. | DOI: 10.2106/JBJS.CC.22.00401 Buy Metrics Abstract Case: Large acetabular paralabral cysts can cause compression of the surrounding neurovascular structures leading to sensory and motor deficits. We present a 68-year-old man with obturator nerve denervation from a paralabral cyst secondary to a labral tear associated with femoroacetabular impingement syndrome. Resolution of symptoms and return to full activities were achieved at 3 months and maintained beyond 1 year through open cyst excision, obturator neurolysis, arthroscopic femoral osteoplasty, and labral repair in the same surgical setting. The patient had a successful clinical outcome, with pain and dysfunction resolution. Conclusion: Large paralabral cysts may cause obturator nerve compression, which can be successfully treated with open nerve decompression and arthroscopic treatment of labral pathology.
