Abstract

Recently it has been postulated that there is an atypical facioscapulohumeral muscular dystrophy (FSHD) phenotype with isolated axial myopathy. Involvement of paraspinal and limb muscles was evaluated in six patients with molecularly proven FSHD and a predominant bent spine phenotype. Consistent with the camptocormia phenotype, the most severely affected muscles in all six patients were the thoracic and lumbar spinal tract together with hamstrings. MRI disclosed severe axial muscle degeneration but mostly subclinical involvement of limb muscles. The involvement of hip extensor muscles in FSHD might considerably contribute to the clinical phenotype of camptocormia due to axial muscle involvement.
