A Case of Hypermobility Syndrome Accompanied by Spontaneous Dislocation of Both Shoulders

ABSTRACT

Hypermobility syndrome (HMS) was first described as a disease entity by Kirk et al. in 1967. It presents hypermobility of a joint without hereditary connective tissue disorders such as Marfan syndrome (MFS), EhlersDanlos syndrome (EDS), or osteogenesis imperfecta (OI). Arthralgia is a common symptom, and dislocation may occur with minimal trauma or even spontaneously. This symptom is often ignored or recognized as non-specific chronic pain because the diagnostic criteria for HMS varies among reserchers and because HSM has no typical radiologic and laboratory findings. We report a case of hypermobility syndrome, which was accompanied by spontaneous dislocation of both shoulders, along a review of appropriate literature on the subject.
