Longitudinal reduction defect of the left radius. This is a congenital condition characterized by an underdeveloped radius bone in the left forearm.
Medical necessity is established by the presence of the congenital defect and its impact on the individual's functional abilities. Treatment, such as surgery or physical therapy, is deemed medically necessary to improve function and quality of life.
Diagnosis and management of this condition typically falls under the purview of pediatricians, orthopedists, and geneticists. They will evaluate the extent of the defect, assess its impact on the child's development, and recommend appropriate treatment strategies.
In simple words: A birth defect where the radius bone in the left forearm is shorter than it should be, which may impact the use of the left hand and arm.
A congenital anomaly where the radius bone in the left forearm is underdeveloped or shortened along its length. This can affect the growth and functionality of the left arm and hand.
Example 1: A newborn infant is examined by a pediatrician and found to have limited movement in their left arm. Radiographic imaging reveals a shortened left radius, consistent with longitudinal reduction defect., A child presents to an orthopedic clinic with a deformed left hand and forearm. After examination and imaging, the physician diagnoses a longitudinal reduction defect of the left radius, a condition present since birth., During a genetic counseling session, a family with a history of skeletal abnormalities is advised about the potential risk of their child being born with conditions such as longitudinal reduction defect of the radius.
Diagnosis requires thorough clinical examination and imaging studies, such as X-rays, to confirm the presence and extent of radial shortening. Documentation should detail the functional limitations observed in the affected limb and any associated anomalies.
** This condition may be associated with other congenital anomalies, including those affecting other limbs or organ systems.
