Area of Science:

Pediatric Orthopedics
Developmental Psychology

Background:

Congenital hip dislocation is a known condition, but voluntary dislocation is exceedingly rare.
Habitual dislocation of the hip typically presents with underlying joint laxity or instability.

Observation:

A 2-year-old female child presented with the unique ability to voluntarily dislocate her right hip.
No other congenital abnormalities or signs of joint hypermobility were noted in the patient.

Findings:

The voluntary hip dislocation in this pediatric case resolved completely after two years of psychological treatment.
This case adds to the scarce literature, with only eight similar instances of habitual hip dislocation previously documented worldwide.

Implications:

Psychological interventions may be a viable treatment for rare cases of voluntary pediatric hip dislocation.
Further research into the neuro-psychological underpinnings of habitual joint dislocation is warranted.
