M21: Other acquired deformities of limbs

M21.5: Acquired clawhand, clubhand, clawfoot and clubfoot

Acquired clawhand, clawfoot, clubhand, and clubfoot refer to deformities of the extremities that can develop due to numerous medical conditions, such as nerve damage, injuries, or underlying health disorders. Specifically, acquired clawhand and clubhand affect the hand and are characterized by abnormal positioning or curvature, often preventing normal use. Typically, individuals with these conditions find the fingers bending improperly or being held in a bent position. On the other hand, acquired clawfoot and clubfoot concern the foot and ankle, with abnormal curvatures that can interfere with standing, walking or running. These deformities vary in severity and can develop gradually over time. Usually, individuals with these deformities may experience discomfort, difficulty in movement or grasping objects, changes in the appearance of the foot or hand, or even loss of function in severe cases. It's important to note that these conditions are not contagious as they result from bodily changes or damage, not infections.
