Hypothesis
Can the peritubercle lucency sign on radiographs predict slipped capital femoral epiphysis in the contralateral hip?
Conclusion
The peritubercle lucency sign can be a useful tool for early diagnosis of slipped capital femoral epiphysis.
Supporting Evidence
- The peritubercle lucency sign was observed in 21 of the 30 patients who developed SCFE in the contralateral hip.
- The sign was present in 95% of cases on lateral views and 85% on AP views.
- Interobserver reliability was measured using the Kappa test with a value of k=0.0801.
- The average follow-up period was 32.8 months.
Takeaway
Doctors can look for a special sign on X-rays to help catch a hip problem early in kids.
Methodology
Retrospective review of patients diagnosed with unilateral SCFE, assessing radiographs for the peritubercle lucency sign.
Limitations
Limited access to previous radiographs and incomplete medical records.
