[Traumatic vasculo-orthopedic combined lesions: 18-years retrospective evaluation of epidemiology and risks factors for amputation].

This study was undertaken to assess retrospectively the epidemiology and risk factors for amputation of combined vasculo-orthopaedic traumatic lesions, during a 18-year period, from March 1987 to May 2005, comprising the review of the clinical charts of 149 patients. The series includes a predominance of male patients (84%) with an average age of 34 years. Eighty-five per cent of the lesions resulted from traffic accidents (49% velocipedes, 39% automobiles, 12% trampling), 10% were consequence of falls and 5% resulted from agriculture activities. Orthopaedic lesions include 83 fractures of upper limbs (22 open), 123 of lower limbs (67 open), 21 scapulo-thoracic dissociations and 27 knee dislocations. Vascular lesions include 8 subclavian, 20 axillary, 25 braquial, 10 radial, 6 ulnar and 2 diverse, in the upper limbs; and in lower limbs 4 iliac, 27 femoral, 52 popliteal, 5 tibio-peroneal trunk, 5 anterior tibial, 12 posterior tibial and 12 peroneal. Overall mortality was 3.3% and the amputation rate was 17%. Knee dislocations were responsible for one third of amputations, followed by fractures of bone legs. The association of femur to bone legs fractures from one side and of the knee to bone legs fractures from the other, coursed with high levels of amputation, together with lacerations and crushing of the limbs. The prompt diagnosis of the lesions and the immediate, hierarchic and multidisciplinary approach were considered also as relevant prognostic factors in the management of these most demanding conditions.
