- type I: enlarged and dysplastic transverse process (at least 19 mm)
- Ia: unilateral
- Ib: bilateral
- type II: pseudoarticulation of the transverse process and sacrum with incomplete lumbarization/sacralization; enlargement of the transverse process with pseudoarthrosis
- IIa: unilateral
- IIb: bilateral
- type III: transverse process fuses with the sacrum and there is complete lumbarization or sacralization, enlarged transverse process with complete fusion
- IIIa: unilateral
- IIIb: bilateral
- type IV: type IIa on one side and type III on the contralateral side
