Nonunion of Proximal Humeral Fracture

Definition

Nonunion of proximal humeral fracture is a condition where a fracture in the upper part of the humerus (the long bone in the upper arm) fails to heal properly, resulting in persistent pain, limited range of motion, and potential instability in the shoulder joint. This can occur due to various factors, such as inadequate blood supply, infection, or improper immobilization.
