Atraumatic hip fracture due to stiff person syndrome: Case report and literature review

Stiff person syndrome (SPS) is a rare autoimmune disorder that affects the central nervous system. Patients with this condition may experience sudden muscle spasms, leading to falls and subsequent fractures. Diagnosis is based on clinical presentation, the presence of anti-GAD antibodies, and electromyography (EMG) findings that show continuous motor unit activity. However, there have been few reports of atraumatic fractures in these patients.
