Table 2.

Occurrence of surgical amputations in the lower limb group stratified by ISS groups and ISS distribution. ISS arbitrarily grouped. The most common injury mechanisms in the amputation group (n = 415, 7 missing) were MVA with motor bicycles (38.6%), followed by pedestrian accidents (17.1%). More than half of the patients (n = 281) had a traumatic amputation, of which 180 (64.1%) were, in addition, surgically amputated. Most patients were amputated on the day of admission according to damage control principles (n = 338, 80.1%).
