Delayed amputation following trauma increases residual lower limb infection

Area of Science:

• Orthopedic Surgery
• Trauma Surgery
• Infectious Disease

Background:

• Residual limb infection is a severe complication of amputation, leading to delayed recovery and poor functional results.
• Identifying predictors of infection is crucial for managing patients with non-salvageable lower limb trauma.

Purpose of the Study:

• To identify variables that predict residual limb infection after amputation for lower limb trauma.
• To determine the impact of timing and surgical management on infection rates.

Main Methods:

• Prospective database analysis of patients with non-salvageable lower limb trauma over 5 years.
• Correlation of clinical and management variables with the development of deep residual limb infection.

Main Results:

• Forty patients underwent 42 amputations, primarily for severe trauma (Gustilo IIIB/IIIC, degloving injuries).
• Amputation within 5 days of injury and following a single debridement significantly reduced stump infections (p=0.026 and p=0.03).
• Injury type and pre-existing patient conditions did not independently predict infection.

Conclusions:

• Prompt amputation is critical for preventing residual limb infections in non-salvageable lower limbs.
• Optimizing surgical timing and debridement protocols can mitigate infection risk.
