A man in his early 40s had revision reconstructive surgery on his left shoulder while in a right lateral decubitus position. The prolonged surgery (7 hours) caused acute compartment syndrome (ACS) in the contralateral (right) thigh. Moderate pain and swelling of the contralateral thigh (‘well limb’) was first noted in the recovery room. After progression to severe swelling and numbness in his right toes, fasciotomies of the right thigh were performed, confirming ACS. Thirteen months later he returned to his prior work without lower extremity discomfort or limitations, and he reported a good result from the revision shoulder surgery. Non-traumatic ACS of a well limb is a rare complication of surgery performed in the lateral decubitus position. We suggest that moving the patient temporarily, or to a new position (eg, beach chair), should be considered when the duration of surgery approaches 4.5 hours.
