Key result
Treatment of developmental dysplasia of the hip led to a significant increase in labrum echogenicity and dimensions on ultrasonography.
Why the study?
The study was conducted to verify morphological changes in the labrum in unstable and dysplastic hips during treatment.
Does treatment for developmental dysplasia of the hip improve labrum morphology on ultrasonography?
Observational (n=74)
Does treatment for developmental dysplasia of the hip improve labrum morphology on ultrasonography?
Treatment of developmental dysplasia of the hip leads to increased labrum echogenicity and dimensions on ultrasound, suggesting a stabilizing role.

Supports ultrasonographic labrum assessment during DDH treatment; leaves open whether changes predict clinical outcomes.
The aim of the study was to verify the labrum's morphological changes in unstable and dysplastic hips during treatment. Between January 2013 and April 2015, 74 dysplastic hips were divided into type D (n=12), type III (n=40), and type IV (n=22). The labrum was evaluated on ultrasonography (US) for echogenicity and dimensions with interobserver/intraobserver tests: test 1 (US at diagnosis and control group), test 2 (US at diagnosis and 6 weeks post-treatment), and test 3 (US at diagnosis and at end of treatment). Statistical analysis was performed. The labrum was less echogenic in test 1 and more echogenic in test 3, and the labrum was smaller in test 1 and larger in test 3. The labrum undergoes statistically significant increase of echogenicity and dimensions after treatment, suggesting a stabilizing role.

Pellegrin et al. (2019) conducted an observational in Developmental dysplasia of the hip (n=74). Treatment for hip dysplasia vs. Baseline (at diagnosis) was evaluated on Labrum echogenicity and dimensions. Treatment of developmental dysplasia of the hip led to a significant increase in labrum echogenicity and dimensions on ultrasonography.
