Muscle imbalance as a cause of scoliosis: a study in a fetal lamb abdominal wall defect model

This fetal lamb study demonstrates that unilateral abdominal wall defects create muscle imbalance leading to ipsilateral scoliosis, with 80% of lambs with organ prolapse developing curves averaging 41-60° Cobb angle. The findings suggest muscle asymmetry may be an underrecognized contributor to scoliosis development in gastroschisis patients.
