T - shape fracture is transverse fracture associated with vertical fracture line breaking the obturator foramen. It breaks the innominate bone into 3 pieces, The Ilium, The Ischium and The Pubis.

It is to be differentiated from fracture of both the columns.

Surgery may either be carried out by anterior Ilio inguinal approach or Kocher Langenbeck approach. Some cases may require simultaneous anterior and posterior approaches.

In this patient the fracture was treated surgically by Posterior Kocher Langenbeck approach. The mode of fixation was interfragmentary screw and reconstruction plate used in neutralisation mode.
