During a 10-year period (1978-1988), 565 patients, aged greater than or equal to 70 years, who sustained a fresh pertrochanteric fracture, were treated in the Department of Traumatology at the University Hospitals of Leuven, Belgium. Three hundred eighty-eight fractures were complex and unstable, according to the Evans-Jensen system and the AO system. Special attention was given to the 324 cases of type IC and ID in Evans' system, type A2 in the AO system. The method of treatment changed greatly during the period of study. All patients were followed prospectively during 1 year. Our study showed that for these unstable fractures, fixation with an angled plate or Ender nails should be forsaken. The overall results of the compression hip screw treatment were good (reoperation rate 2%, good functional results in 64%), but as this treatment has a risk for serious collapse and pain in about 80% of all type ID fractures, one could suggest treating these complex multifragment fractures primarily with an endoprosthesis. This treatment need no longer be considered severe intervention, as the danger of mechanical complications is minimal (less than 1%).
