Abstract

The EULAR Executive Committee defined eight overall objectives for EULAR to achieve by 2012. The first of these objectives is to strengthen activities in areas that are currently less prioritized, such as non-inflammatory and orphan diseases. This study aims to increase awareness of rheumatologists towards rare hereditary musculoskeletal disorders, by describing their genetics, pathogenesis, and typical clinical and radiological features. We analyzed patient charts from the recent 5 years from the Rheumatology Outpatient Department of the University Erlangen-Nuremberg and of two rheumatologic practices, all joined in a regional network (“Rheumazentrum Erlangen”) retrospectively for hereditary musculoskeletal disorders other than hemochromatosis, autoinflammatory syndromes, lysosomal storage diseases, and hypermobility syndromes. We were able to identify four patients with trichorhinophalangeal syndrome type I, multiple exostoses, Kirner’s deformity, and osteopoikilosis. In addition, a PubMed and OMIM (“Online Mendelian Inheritance in Man”) database search was carried out using these as key words and all relevant articles were reviewed for each of these diseases. Our findings show that rare hereditary musculoskeletal disorders occur in a routine rheumatological setting and that rheumatologists should know the clinical and radiological features of these diseases in order to adequately counsel the patient.
