There are
various factors that affect the fracture healing process. These factors are separated
into two categories - local variable and systematic variables .Both of them
affect the rate and the degree of the healing of broken bones. When the
fracture healing process takes more time than it usually takes, it is called as
delayed union. If the bones do not join, it is termed as non-union. Certain
factors are responsible for these problems, including the following:
1. Systemic factors
*Age - Age is a major factor in the
healing process of any broken bone. It is faster in children than in adults.
The bones of a baby are made of cartilages also they have ability to repair and
heal at a faster rate.
*Nutrition - Sufficient amount of
nutrients are essential for the healing of broken bones. Nutrients like
carbohydrates and proteins are required in adequate quantity. Vitamin C helps
calcium to absorb calcium from blood.
*Systemic diseases-A person having diabetes
will likely experience delay in healing.
*Hormones - Hormones such as calcitonin
and thyroid also play a vital role during the treatment of fractures.
2. Local variables.
*Type of
bone - Different bones take different time to heal.
*Degree of
trauma - If the injury is severe and it has damaged the surrounding tissues, it
will take more time to heal.
*Vascular
injury - Due to vascular injury, blood supply is affected, which may result in
delayed healing.
*Degree of
immobilization - Immobilized fractured parts heal faster. If the fractured bone
keeps moving, this may cause further injury.
The healing
of fractures is influenced by multiple variables.
