143 Possible Causes for Coronal Cleft of Vertebrae, Percussion Myotonia

  • Schwartz-Jampel Syndrome

    Further investigation showed some typical facial features of the syndrome, percussion myotonia and abnormal EMG pattern characterized by continuous muscle activity at rest[] cleft vertebrae 0003417 Joint contracture of the hand 0009473 Kyphoscoliosis 0002751 Low-set ears Low set ears Lowset ears [ more ] 0000369 Lumbar hyperlordosis Excessive[] He had diffuse muscular hypertrophy and stiffness with eyelid myotonia, tongue myotonia, percussion myotonia at thenar eminence [Figure 2] and forearm muscles.[]

  • Paramyotonia Congenita

    They experience neither grip nor percussion myotonia during warm weather, whereas myotonia is provoked by cold. Her younger son has no symptoms.[] Also of diagnostic importance are the myotonic reactions inducible at room temperature, such as percussion myotonia, active myotonia and paradoxical myotonia.[] Percussion myotonia of the tongue and thenar muscles could be elicited at room temperature. Myotonia was aggravated by cold.[]

  • Generalized Myotonia of Thomsen

    On examination he showed percussion myotonia. There was no grip myotonia or eyelid myotonia. Nerve conduction studies were normal.[] Secondary outcomes: (1) clinical relaxation time; (2) electromyographic relaxation time; (3) stair test; (4) presence of percussion myotonia; and (5) adverse events.[] Proband shows percussion myotonia of the tongue.[]

  • Kniest Dysplasia

    Two key features to look for in a patient with Kniest dysplasia is the presence of dumb-bell shaped femur bones and coronal clefts in the vertebrae.[] In infancy, coronal clefting may be seen in the lumbar vertebrae. The ilia are broad with hypoplastic basilar portions.[]

  • Rhizomelic Chondrodysplasia Punctata Type 1

    clefting of the vertebrae, dwarfism with rhizomelic shortening of the limbs, joint contractures, congenital cataracts, ichthyosis, and mental retardation.[] The vertebrae have coronal clefting. The cartilage abnormalities result in defective bone growth with severe growth retardation, short stature, and joint contractures.[] (Conradi-Hünermann syndrome), and a milder X-linked form. chon·dro·dys·pla·si·a punc·ta·'ta [MIM*215105] a developmental disorder characterized by epiphysial stippling, coronal[]

    The diagnosis were based upon family history, clinical findings of percussion myotonia, had grip myotania, prominent muscular hypertrophy and confirmed by electromyographic[] Distribution/anatomy Time course Onset/age Myotonia is usually mild, approximately 50% may have percussion myotonia.[] On examination he showed percussion myotonia. There was no grip myotonia or eyelid myotonia. Nerve conduction studies were normal.[]
