Sequelae of an undiagnosed unilateral congenital fixed anterior shoulder dislocation in a 40-year-old female.

Congenital shoulder dislocation is a rare condition. A review of the literature showed that 0.018-0.07% of newborns suffer from shoulder dislocations. There have been only few reports about this entity, clinic and radiologic features, treatment, and etiology of this condition remains unclear. We report a case of undiagnosed unilateral congenital fixed anterior shoulder dislocation in a 40-year-old female, which affected the day quality of life. Pediatrists and orthopaedic surgeons should know this rare condition and the importance of a proper diagnosis in the early childhood when an appropriate treatment could be performed.
