ICD-10: Q78.5

Metaphyseal dysplasia, classified under ICD-10-CM code Q78.5, is a rare skeletal disorder characterized by abnormal development of the metaphysis, the region of long bones where growth occurs. This condition can lead to various skeletal deformities and may affect the overall growth and development of affected individuals.

Clinical Description

Definition and Characteristics

Metaphyseal dysplasia refers to a group of disorders that primarily affect the metaphyseal region of bones, leading to a range of skeletal abnormalities. The condition is often associated with a variety of clinical features, including:

• Bone Deformities: Patients may exhibit bowing of the long bones, particularly in the legs, which can lead to difficulties in mobility and increased risk of fractures.
• Short Stature: Individuals with metaphyseal dysplasia often present with shorter than average height due to impaired growth at the growth plates.
• Joint Problems: There may be associated joint issues, including osteoarthritis, due to abnormal bone structure and alignment.

Genetic Factors

Metaphyseal dysplasia can be caused by genetic mutations that affect bone growth and development. Some forms of the condition are inherited in an autosomal dominant pattern, while others may arise sporadically. Genetic counseling may be beneficial for affected families to understand the inheritance patterns and risks for future offspring[1][2].

Associated Conditions

In some cases, metaphyseal dysplasia may be part of a syndrome that includes other systemic features, such as intellectual disabilities or conductive hearing loss. For instance, certain forms of metaphyseal dysostosis are linked to additional neurological or sensory impairments[3][4].

Diagnosis

Clinical Evaluation

Diagnosis typically involves a thorough clinical evaluation, including:

• Medical History: Gathering information about growth patterns, family history of skeletal disorders, and any associated symptoms.
• Physical Examination: Assessing for physical signs of skeletal deformities, joint issues, and overall growth parameters.

Imaging Studies

Radiological imaging, such as X-rays, is crucial for diagnosing metaphyseal dysplasia. X-rays can reveal characteristic changes in the metaphyseal regions of bones, including:

• Widening or irregularity of the metaphysis
• Changes in bone density
• Alterations in the shape of the long bones

Genetic Testing

In cases where a genetic cause is suspected, genetic testing may be performed to identify specific mutations associated with the condition. This can aid in confirming the diagnosis and guiding management strategies[5][6].

Management and Treatment

Multidisciplinary Approach

Management of metaphyseal dysplasia often requires a multidisciplinary approach, involving:

• Orthopedic Intervention: Surgical options may be considered to correct significant deformities or to address joint problems.
• Physical Therapy: Rehabilitation services can help improve mobility and strength, enhancing the quality of life for affected individuals.
• Regular Monitoring: Ongoing assessment of growth and skeletal development is essential to manage potential complications effectively.
