What is indicated by the presence of verrucous hyperplasia on the distal end of a limb?

The presence of verrucous hyperplasia on the distal end of a limb typically indicates a lack of total contact between the socket and the residual limb. This condition arises when there are areas of high pressure or shearing forces, which can occur when the surface of the socket does not fully engage with the limb. As a result of these uneven pressures, the skin can respond by developing verrucous hyperplasia, which is characterized by thickened, wart-like lesions.

Achieving total contact in a prosthetic socket is crucial for ensuring even distribution of forces throughout the residual limb, minimizing the risk of pressure sores and skin changes. When the socket design does not accommodate the entire limb properly, it can lead to specific skin issues, such as verrucous hyperplasia, reinforcing the importance of proper socket fit and alignment in prosthetic practice.
