ICD-10: Q71.43

The ICD-10 code Q71.43 refers to a specific congenital condition known as the longitudinal reduction defect of the radius, which occurs bilaterally. This condition is classified under the broader category of congenital malformations of the musculoskeletal system.

Clinical Description

Definition

A longitudinal reduction defect of the radius is characterized by an abnormality in the development of the radius bone, which is one of the two long bones in the forearm. In this condition, the radius is either shortened or malformed, leading to functional impairments in the affected individual. When the defect is bilateral, it means that both forearms are affected, which can significantly impact the patient's mobility and functionality.

Etiology

The exact cause of longitudinal reduction defects is often unknown, but they are believed to arise during the early stages of fetal development. Genetic factors, environmental influences, or a combination of both may contribute to the occurrence of this defect. It is important to note that these defects can be associated with other congenital anomalies, which may complicate the clinical picture.

Clinical Features

Patients with bilateral longitudinal reduction defects of the radius may present with several clinical features, including:
