There is no bone in the human body that never heals. While some fractures may take a longer time to heal or may not heal properly, with the right treatment and care, bones can heal even in cases of delayed union or nonunion.
A nonunion occurs when the broken ends of a bone do not join together, while a delayed union indicates that the healing process is significantly slower than expected. These complications are more common in certain bones, such as the humerus (upper arm) and the tibia (lower leg), and can be influenced by factors like the severity of the fracture, the presence of infection, or poor blood supply.
It is important to note that while there's no bone that never heals, some fractures can be more challenging to treat and may require additional procedures like surgery or bone grafting to promote healing.
