Delayed union, a fracture healing failure, often occurs because the exact cause is unknown. This review explores the pathophysiology of delayed healing, considering patient and injury factors.

Area of Science:

  • Orthopaedic surgery
  • Bone healing pathophysiology

Background:

  • Delayed union is a common complication in fracture management.
  • The underlying reasons for delayed healing are frequently unclear, hindering effective treatment.

Purpose of the Study:

  • To review the limited available literature on the pathophysiology of delayed fracture healing.
  • To identify key factors contributing to the failure of bone repair.

Main Methods:

  • Literature review focusing on the pathophysiology of delayed union.
  • Analysis of systemic, local, and treatment-related factors affecting fracture healing.

Main Results:

  • Factors influencing delayed healing include patient's systemic status, pre-injury limb condition, injury characteristics, host response, orthopaedic care, and pharmacologic variables.

  • Understanding these multifactorial elements is crucial for addressing non-union complications.

    • Conclusions:

    • Delayed union results from a complex interplay of patient-specific, injury-related, and treatment-associated factors.
    • Further research into the precise pathophysiology is needed to improve fracture management outcomes.
