Preoperative pars defect length predicts bone union after direct repair for lumbar spondylolysis using the modified smiley face rod technique: a retrospective cohort study
Bone union following the mSFR technique may be influenced by the pars defect length, with larger preoperative defects potentially hindering bone union. The technique is most effective when the preoperative defect length is ≤3.8 mm.
