Objective:

To assess abdominal wall symmetry after reconstruction of traumatic lumbar hernia using the Abdominal Symmetry Index (ASI).

Approach:
  • Study Design: Single-center retrospective comparative study conducted at a tertiary academic referral center.
  • Study Population: Included 50 individuals: 25 with traumatic lumbar hernia (TLH group) and 25 controls without abdominal wall abnormalities.
  • CT Assessment: Abdominal symmetry was assessed using axial CT images, measuring distances from the midline to the lateral abdominal wall contour.
Key Findings:
  • The ASI was defined as the ratio of distances measured on the hernia side to the contralateral normal side.
  • Values closer to 1 indicate greater symmetry.
Interpretation:

Limitations:
  • The study was not designed to demonstrate superiority of the repair technique over others.
  • Patient satisfaction and hernia-specific function were not primary endpoints.
Conclusion:

The study presents ASI as an exploratory morphologic index for assessing abdominal symmetry post-reconstruction.
