Because the physical examination is so insensitive, ultrasound imaging to assess the size of the spleen at three weeks may be a better guide for determining whether a patient should return to athletics.37 The cost to prevent one traumatic rupture probably is well over $1 million when this strategy is used, given that the risk of rupture overall is one in 1,000, the risk of rupture beyond four weeks is considerably less, about one half of ruptures are atraumatic, and the cost of an ultrasound scan is several hundred dollars.
