Delayed union
Delayed Union
Delayed union is a term used in Orthopedics to describe a state where the healing process of a fracture is slower than usual.
Pronunciation
De-lay-ed U-nion
Etymology
The term is derived from the English words "delayed", meaning postponed or deferred, and "union", referring to the process of joining together. In this context, it refers to the postponed joining or healing of a fracture.
Definition
A delayed union is defined as a fracture that has not united in the expected time frame, typically within 3 to 4 months after the fracture. This condition is different from a nonunion, where the fracture fails to heal without intervention.
Causes
Delayed union can be caused by several factors including poor blood supply, infection, inadequate immobilization, and systemic conditions such as diabetes or osteoporosis.
Treatment
Treatment for delayed union may involve bone grafting, electrical stimulation therapy, or surgery to stabilize the fracture. Medications such as bisphosphonates may also be used to promote bone healing.
