Summary
Major lower limb amputation carries significant mortality, with 1-year survival at 21.1%. Risk factors include peripheral vascular disease and older age, emphasizing the need for preventative strategies to reduce amputation rates.
Area of Science:
- Surgical outcomes
- Public health
- Epidemiology
Background:
- Major lower limb amputation is a last resort for end-stage pathology.
- Previous treatments often fail before amputation is considered.
Purpose of the Study:
- Determine 30-day and 1-year mortality rates for nontraumatic major lower limb amputations.
- Identify risk factors for poor outcomes.
- Assess rates of previous minor and subsequent major amputations.
Main Methods:
- Retrospective review of 147 nontraumatic major lower limb amputations over 18 years.
- Mortality data sourced from the Queensland Registry of Births, Deaths and Marriages.
- Kaplan-Meier analysis used for survival assessment.
Main Results:
- Overall 30-day mortality was 4.1%; 1-year mortality was 21.1%.
- Indigenous patients had a 30-day mortality of 10%.
- Risk factors for mortality included peripheral vascular disease, ASA score of 4, and age >65.
Conclusions:
- Major lower limb amputation is associated with substantial morbidity and mortality.
- Preventative measures are crucial to reduce future amputation incidence.

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
