I :
hematoma: subcapsular , <10% surface area
laceration: capsular tear <1cm parenchymal depth
II
hematoma: subcapsular , 10-50% surface area , intra-parenchymal <5cm diameter
laceration: 1-3cm parenchymal depth not involving a parenchymal vessel
III
hematoma: subcapsular, >50% surface area or expanding , ruptured subcapsular or parenchymal hematoma , intraparenchymal hematoma >5cm
laceration: >3cm parenchymal depth or involving trabecular vessel
IV
laceration : of segmental or hilar vessels producing major devascularization (>25%of spleen)
