Abstract
Background
: Hip dysplasia is present in approximately 1-4% of the adult population and is associated with pain and eventually osteoarthritis. Despite the high prevalence of hip dysplasia, there is little known about the heritability and the factors associated with developing pain and disability. The aim of this study was to document the prevalence of hip dysplasia in parents of young adults treated with periacetabular osteotomy (PAO) for hip dysplasia and determine risk factors for pain, osteoarthritis, and total hip arthroplasty in these parents.
Methods
: Parents of young adults from age 13-27 years old with hip dysplasia indicated for PAO at our institution were enrolled. Both biologic parents were required to participate for eligibility. Study participants completed the international Hip Outcome Tool (iHOT), family and personal history of hip pain, disability, treatment, and history of youth sports participation. Standing AP pelvis and bilateral Dunn lateral radiographs were completed for each enrolled parent. Radiographic dysplasia was defined as lateral center of edge angle (LCEA) <25 or Tönnis angle >11. Composite hip failure was defined as iHOT <63 Tönnis grade >2, or total hip arthroplasty. Categorical variables were summarized as frequencies (percentages) and continuous variables as means(standard deviations) with chi-square and independent t-tests used for group comparisons, respectively.
Results
: There were 25 sets of parents that completed surveys and radiographs. Mothers versus fathers did not significantly differ in average iHOT scores (82.2±17.3 vs 88.1±18.1, p=0.248), prevalence of dysplasia (36% vs 48%, p=0.390) or composite failure (72% vs 88%, p=0.157). In the maternal cohort, there was a significantly higher frequency of composite hip joint failure with dysplastic (100%) vs non-dysplastic hips (56%, p=0.027). In the paternal cohort, however, rates did not significantly differ (92% vs 85%, p=1.000)
Conclusions
: Radiographic hip dysplasia was very common in parents of young adults treated for hip dysplasia with PAO. Despite a lower prevalence of hip dysplasia compared with fathers, a significant relationship between radiographic hip dysplasia and composite hip joint failure was only detectable in mothers. These results suggest that female hip joints are more sensitive to reduced lateral coverage seen in hip dysplasia.
