Pediatric Voluntary Habitual Hip Dislocation: Clinical Characteristics, Family Dynamics, and Long-Term Outcomes-A...

Background/Objectives: Recurrent hip dislocations are a rare occurrence in pediatric patients. As there are few cases of voluntary habitual dislocation documented in the literature, there is a paucity of information available regarding its pathogenesis, risk factors, and classification. The prognosis for these patients is generally good. A long-term follow-up duration of two years was conducted to evaluate outcomes. Statistical analysis was performed to assess the impact of family structure and treatment approaches on outcomes. Methods: From January 2010 to December 2022, patients with voluntary habitual hip dislocation were retrospectively identified through the hospital information system. Data regarding demographic characteristics, clinical findings, and treatment outcomes were analyzed. A total of 13 patients (14 hips) met the inclusion criteria. Conservative treatment methods, including orthosis and family therapy, were applied. Statistical analysis was performed to assess the impact of family structure and treatment approaches on outcomes. Results: The mean age at diagnosis was 48.7 months, with 77% of cases being female. Posterior dislocation was observed in all cases, and no underlying bone pathology was detected on imaging. The prognosis for these patients is generally good. At the one-year follow-up, 85% of patients achieved a complete resolution of dislocations, increasing to 100% by the two-year follow-up. Patients from larger families demonstrated significantly slower recovery rates at the first- and sixth-month evaluations (p = 0.033 and p = 0.048, respectively), but outcomes were comparable by one year. A unique aspect of this study is the emphasis on family dynamics, which significantly influenced treatment adherence and recovery. Statistical analysis was performed to assess the impact of family structure and treatment approaches on outcomes. Conclusions: Voluntary habitual hip dislocation is a rare condition with good long-term outcomes under conservative management. This study highlights the importance of addressing family dynamics in the treatment plan, especially in larger families, where attention and psychological factors may play a significant role in delayed recovery.
