13 Possible Causes for Hypertonicity of the Lower Limbs, Malocclusion

  • Cerebral Palsy

    We looked for a possible association between overall functional impairment and malocclusion in this population.[ncbi.nlm.nih.gov] All had spasticity affecting predominantly the lower limbs, although 2 also had mild hypertonia and ataxia of the upper limbs.[ncbi.nlm.nih.gov] This article reports the treatment of a 12-year-old girl with ataxic cerebral palsy; she had a dental and skeletal Class II malocclusion, maxillary transverse deficiency,[ncbi.nlm.nih.gov]

  • Osteogenesis Imperfecta Type 13

    This occlusal observation is significant as it often tends to progress to an adult Class III dental malocclusion and a potential skeletal Class III malocclusion.[nature.com] Apart from mild hyperreflexia, the upper limbs were normal. However, the lower limbs were markedly hypertonic with brisk reflexes and sustained ankle clonus.[jnnp.bmj.com] […] appearance of small deformed teeth and which are opalescent due to a higher ratio of transparent enamel to opaque dentin is called dentinogenesis imperfecta and along with malocclusion[ijem.in]

  • Osteogenesis Imperfecta Type 3

    This occlusal observation is significant as it often tends to progress to an adult Class III dental malocclusion and a potential skeletal Class III malocclusion.[nature.com] Apart from mild hyperreflexia, the upper limbs were normal. However, the lower limbs were markedly hypertonic with brisk reflexes and sustained ankle clonus.[jnnp.bmj.com] […] appearance of small deformed teeth and which are opalescent due to a higher ratio of transparent enamel to opaque dentin is called dentinogenesis imperfecta and along with malocclusion[ijem.in]

  • Warburg Micro Syndrome 3

    ASD, VSD, valvular malformations - moderate facial dysmorphism: wide frontal bossing, triangular face in childhood but oval later; downslanting palpebral fissures - dental malocclusion[sites.uclouvain.be] , hypertonic lower limbs with contractures, myoclonic seizures, and hypoplastic labia minora and clitoral hypoplasia.[bio2rdf.org] Upper limbs are hypotonic and lower limbs hypertonic. Deep tendon reflexes are brisk. Pupil is atonic [Figure 2] .[pediatricneurosciences.com]

  • Spastic Paraplegia Type 2

    FACIES, AND PSYCHOMOTOR RETARDATION 1 Macrocephaly with Multiple Epiphyseal Dysplasia and Distinctive Facies 1 Macrocephaly, Macrosomia, and Facial Dysmorphism Syndrome 1 Malocclusion[rgd.mcw.edu] limb hypertone.[slideheaven.com] The lower limb spasticity is the prominent finding on examination, particularly in the hamstrings, quadriceps, and ankles.[jnnp.bmj.com]

  • Brooks Wisniewski Brown Syndrome

    Loucks-Innes Syndrome Lowry Maclean syndrome Lowry Wood Syndrome Macrocephaly, Macrosomia, and Facial Dysmorphism Syndrome Macrosomia Adiposa Congenita Madelung Deformity Malocclusion[rgd.mcw.edu] There was also a tendency to hypertonicity with deLange sign (crossing of lower limbs).[documents.tips] Constriction of peripheral visual field Cutaneous syndactyly Increased intracranial pressure Anosmia Increased bone mineral density Finger syndactyly Overgrowth Tall stature Dental malocclusion[mendelian.co]

  • Cataract - Ataxia - Short Stature - Mental Retardation (CASM)

    Ocular Abnormalities Madelung Deformity Male Hypogonadism with Mental Retardation and Skeletal Anomalies Male Pseudohermaphroditism/Mental Retardation Syndrome, Verloes Type Malocclusion[rgd.mcw.edu] […] of the lower limbs NEUROLOGIC: [Central nervous system]; Delayed psychomotor development; Mental retardation, mild to severe; Spasticity, more apparent in the lower limbs[findzebra.com] Prognathism with a prominent lower lip and dental malocclusion reinforce this appearance. Seizures beginning in early childhood may be difficult to control.[disorders.eyes.arizona.edu]

  • Cerebro-Oculo-Facio-Skeletal Syndrome 1

    Intraoral examination revealed a Class III malocclusion with a negative over jet and deep overbite.[jomfp.in] Upper limbs are hypotonic and lower limbs hypertonic. Deep tendon reflexes are brisk. Pupil is atonic [Figure 2].[pediatricneurosciences.com] Due to the discrepancy between the size of the jaws and the teeth, malocclusion and crowding are frequent.[ojrd.biomedcentral.com]

  • Al-Gazali-Dattani Syndrome

    […] deficiency Large hands Motor delay Dental crowding Recurrent skin infections Sacral dimple Accelerated skeletal maturation Pointed chin Long eyelashes Renal dysplasia Dental malocclusion[mendelian.co] All had spasticity affecting predominantly the lower limbs, although 2 also had mild hypertonia and ataxia of the upper limbs.[findzebra.com] […] failure and Abnormality of the pinna, related diseases and genetic alterations Fever and Ambiguous genitalia, related diseases and genetic alterations Hydrocephalus and Dental malocclusion[mendelian.co]

  • Autosomal Dominant Microcephaly

    Dental malocclusion becomes apparent in early childhood and persists into adulthood, affecting the permanent dentition as well.[ncbi.nlm.nih.gov] He had a high arched palate, prominent large ears, pointed chin, spasticity and atrophy of the upper and lower limbs, right-side cryptorchid testis and bilateral overlapping[scielo.br] […] clitoris and labia majora), dysmorphic facial features (widely spaced and prominent eyes, frontal bossing, anteverted nares, midface retrusion), dental abnormalities (including malocclusion[ncbi.nlm.nih.gov]
