Q72: Reduction defects of lower limb

Reduction defects of lower limb, classified under the Q72 ICD-10 code range, include a group of medical conditions characterized by the underdevelopment or absence of one or more parts of the lower extremity. These conditions are congenital, meaning they are present from birth, and result from disruptions in the normal development process during the early stages of pregnancy. The specific cause of these defects is typically unknown but may be related to genetic, environmental, or maternal health factors. Symptoms vary broadly based on the specific type and severity of the reduction defect but generally include functional and mobility impairments due to the abnormalities in the legs, feet, or toes. Over time, the condition may progress, and symptoms may change or worsen based on growth, development, and the physical demands placed on the affected limb. Reduction defects primarily affect the musculoskeletal system, particularly impacting bone structure and muscle function.
