Which defect includes missing parts but retains some distal structure?

Incomplete phocomelia refers to a condition where there is a significant reduction of limb structure, but some of the distal elements remain intact. This means that while parts of the limb may be missing or severely underdeveloped, there is still a recognizable distal part, such as a hand or foot, present. This distinguishes it from complete phocomelia, where the limb is essentially absent or appears as a small, rudimentary structure without any distal components.

Understanding this condition is crucial for designing appropriate prosthetic solutions and rehabilitation strategies, as the presence of distal structures can impact function and the type of orthotic or prosthetic interventions that may be beneficial. Incomplete phocomelia often requires careful planning and customization, highlighting the importance of thorough assessment and collaboration with healthcare professionals in the field to optimize patient outcomes.
