An adjustable support arm for an operating room table includes an attachment, a support rod having an end pivotally attached to the attachment and pivotable about a lithotomy axis, and a lithotomy locking cylinder operably attached to the support rod. The lithotomy locking cylinder can be unlocked to raise or lower the support rod about the lithotomy axis and locked to retain the support rod in the desired lithotomy position. The lithotomy locking cylinder is infinitely adjustable over a range and can provide an assisting lift force. The support rod can also be pivotable about an abduction axis with an abduction locking cylinder operably attached to the support rod. The abduction locking cylinder can be unlocked to laterally pivot the support rod about the abduction axis and locked to retain the support rod in the desired abduction position. The abduction locking cylinder is infinitely adjustable over a range and can provide a bias force to a minimum abduction position.
