Surface marking of Spleen

Spleen is situated behind 9th, 10th and 11th ribs with its long axis along the line of 10th rib; anteriorly it extends to mid axillary line while posteriorly its superior angle is 4 cm  lateral to 10th thoracic spine. It is separated from 9th, 10th and 11th ribs by the diaphragm.
Surface marking of spleen can be done by joining 3 points
  • 9th Left intercostal space – midclavicular line.
  • 1.5" to the left of 10th spine
  • 3.5" to the left of 1st lumbar spine
