Regarding the sequelae of comminuted fractures of the humerus, in clinical practice, if treatment for humerus comminuted fractures is proactive and patients diligently engage in functional exercises without any nerve damage, most patients will not experience any sequelae. However, if treatment is improper, a series of sequelae can often occur, mainly reflected in the following aspects:

First, if there is accompanying nerve damage that is very severe, it can cause patients to experience sensory disturbances or motor function impairments.

Second, poor repositioning of comminuted fractures can lead to nonunion or malunion of the fracture, affecting normal functions of the patient.

Third, long-term immobilization in the later stages can cause joint stiffness. When patients eventually start exercising, fear of pain may lead to insufficient exercise, resulting in very poor joint mobility, thereby affecting normal functions.
