    Talus fractures are uncommon injuries. This study found avascular necrosis and osteoarthritis in 33% of talar lesions, though non-union was absent.

    Area of Science:

    • Orthopedic Surgery
    • Traumatology
    • Bone Healing

    Background:

    • Talus injuries represent a rare but complex subset of lower extremity trauma.
    • These fractures often involve significant soft tissue damage and pose challenges in management.
    • Understanding complication rates is crucial for optimizing patient outcomes.

    Purpose of the Study:

    • To retrospectively analyze the complications associated with a large cohort of talar lesions.
    • To identify the incidence of secondary displacement, infection, non-union, avascular necrosis, and osteoarthritis.
    • To evaluate factors influencing complication rates, such as accurate fracture reduction.

    Main Methods:

    • Retrospective review of 359 cases with talar lesions.
    • Data collection on fracture patterns, injury severity, and treatment interventions.

  • Assessment of short-term and long-term complication rates including infection, non-union, avascular necrosis, and osteoarthritis.

    • Main Results:

    • Secondary displacement was observed in 8% of cases.
    • Bone infection rates were low despite frequent primary skin injuries (20%).
    • Avascular necrosis (body or trochlea) occurred in 33%, potentially preventable by accurate reduction.
    • Osteoarthritis developed in 33% of patients.
    • Bone fusion was consistently slow, but no non-unions were recorded.

    Conclusions:

    • Talus fractures exhibit a significant risk of avascular necrosis and osteoarthritis.
    • Accurate reduction of talar fractures is critical for mitigating avascular necrosis.
    • While bone fusion may be delayed, non-union appears to be rare in talar injuries.
