Aly I, Chapman JR, Oskouian RJ, Loukas M, Tubbs RS.Lumbar ribs: a comprehensive review.Childs Nerv Syst. 2016 May;32(5):781-5. doi: 10.1007/s00381-015-2904-2. 

ABSTRACT

BACKGROUND:

To date, no single comprehensive review has been published regarding lumbar ribs. Therefore, the present review was conducted to better elucidate these variant anatomical structures, which can be confused with transverse process fractures or result in miscounting of spine segments for surgical procedures.

METHODS:

Using standard search engines, a review of lumbar ribs was performed.

CONCLUSIONS:

Lumbar ribs are uncommon but can be misinterpreted on imaging or cause confusion during surgery. Mutations of the FGD1 or Hox10 gene may be involved in the development of lumbar ribs. Knowledge of these structures can decrease misdiagnosis when they are present.
