Background: Heterotopic ossification (HO) is a rare but known complication of brain and nerve trauma, orthopedic trauma, and burns. Nerve compression due to HO is extremely rare; "bony cubital tunnel syndrome," or compression of the ulnar nerve at the elbow due to HO, is an unusual presentation that requires special considerations for treatment.
Case Presentation: We present a 50-year-old man who presented to our hospital after vehicular polytrauma with associated car fire and prolonged extrication.
