A digit amputation with a palpable posterior tibial pulse has what approximate chance of healing?

A digit amputation with a palpable posterior tibial pulse has what approximate chance of healing?

• A. 60%
• B. 75%
• C. 90%
• D. 100%

Answer: (C)

The main idea is that tissue healing after a digit amputation depends heavily on adequate blood flow. A palpable posterior tibial pulse means good arterial inflow to the foot, supplying oxygen and nutrients essential for wound repair, immune defense, and tissue regeneration. With that level of perfusion, the digit has a very high potential to heal, which is typically around 90% in this scenario. In other words, when the pulse is present, healing is very likely but not guaranteed—factors like infection, osteomyelitis, or systemic conditions can still affect outcomes.
