M21.9: Acquired deformity of limb, unspecified

The condition known as "Acquired deformity of limb, unspecified" generally refers to a health issue that results in abnormal changes in shape or size of a limb, which has been acquired and not present from birth. It can be caused by various health conditions, infections, injuries or medical interventions. The deformity can present in a range of forms, such as the bending of a limb that deviates from its normal alignment or even changes in length. It may affect the individual's normal function depending on the severity and location. Symptoms can vary widely depending upon the nature of the deformity - from slight discomfort to greater functional disability. These changes can manifest gradually or suddenly, depending on the root cause. The limbs most commonly affected can be arms, legs, hands, or feet.
