The stiff-person syndrome is a rare and progressive neuromuscular disease which appears to have an immunpathological basis. It is characterised by painful muscle spasms and stiffness in the proximal muscles, especially those attached to the axial skeleton. The precise pathophysiology is still unknown, but several antibodies have been shown to be present in patients and these antibodies are directed against proteins which play a role in the inhibitor synapse linked to gamma-amino-butyrate. In the first part of the article the authors present two cases. In the second part they present a comprehensive review of our current knowledge about this rare disease.

Background And Objectives: Autoantibodies (aAbs) against glycine receptors (GlyRs) are mainly associated with the rare neurologic diseases stiff person syndrome (SPS) and progressive encephalomyelitis with rigidity and myoclonus (PERM). GlyR aAbs are also found in other neurologic diseases such as epilepsy. The aAbs bind to different GlyR α-subunits and, more rarely, also to the GlyR β-subunit.

We describe a woman with stiff-person syndrome (SPS), whose muscle spasms resulted in sequential bilateral femoral neck fractures. Orthopaedic fixation of the first fracture was complicated by increased muscle spasm, fracture nonunion and ultimately metalwork fracture. SPS was diagnosed following the fracture of the contralateral femoral neck, neurology assessment and detection of high-titre antibodies to glutamic acid decarboxylase.
