NCT05914298

Brief Summary

the purpose of the present registry is to describe the epidemiology of forearm deformities in patients with Hereditary Multiple Exostoses and to identify, independent predictors of severity of the disease and potential association with genotypic patterns

Outcome Measures

Primary Outcomes (1)

  • proportional ulnar length (PUL)

    proportional ulnar length (PUL) is the ratio between ulnar lenght and the height of the patient

    1 year

Secondary Outcomes (3)

  • genotype

    1 year

  • forearm function

    1 year

  • EuroQol 5D

    1 year

Study Arms (2)

HME group

204 children and adult patients with HME, admitted to our Hospital for diagnosis and treatment. the patients will be stratified by age in four subgroups: * subgroup I (0-7 Years) * subgroup II (8-12 Years) * subgroup III (13-18 Years) * subgroup IV (\>18 Years)

Diagnostic Test: blood and buccal swab genetic testDiagnostic Test: PULDiagnostic Test: Range of motion

healty control group

204 children and adult voluntary healty controls will be stratified in the same manner and matched with the population in study in order to assess normal and pathologic growth.

Diagnostic Test: PULDiagnostic Test: Range of motion

Interventions

blood samples and buccal swabs will be obtained from patients with HME in order to analyze the genotype (EXT1 or EXT2 mutations) and correlate the genotypic pattern with the phenotypic presentation

HME group
PULDIAGNOSTIC_TEST

measurement of ulnar length with anthropometer and patient's height
