ABSTRACT
Purpose: Show that the recreation of the up-straight position by means of gravitational sequence is key to assessing lumbar pain with neuroforaminal origin.Material and Methods: A total of 20 subjects (eleven women and nine men) were assessed, chosen between July 15 and September 30, 2004; ages between 26 and 54 years, with a mean of 42 years old. All patients presented clinical lumbar pain, with or without irradiation, as well as paresthesias. Images were obtained from a 1.5T Signa EchoSpeed Twin (General Electric) equipment using a surface antenna, and collecting sagittal and axial images, before and after the placement of the gravitational simulator, in T1 and T2 sequences.
Results: Of the 20 subjects, 12 show significant changes after applying the gravity simulating sequence, which includes the increase of the disk protrusion and a higher sacral dural compromise and the emergence of roots (five patients) (25%); convex form of the fibrous ring and contact with nerve origins (4 patients) (20%); and convex form of the disk ring (3 patients) (15%).
Conclusion: As with other series performed, it is shown that when recreating the supine position by means of a gravitational simulator, the neuroforaminal pathology is greatly increased compared to traditional sequences, observing that in 20% of all our patients, while no alteration was observe with conventional studies. The findings with the gravitational sequence were conclusive.
