In a prospective, consecutive, randomized study of the treatment of
unstable intertrochanteric fractures of the hip, the use of Ender pins was
compared with the use of the compression hip-screw. There were more than
100 patients in each treatment group. The patients who were alive six
months postoperatively were evaluated. The number of secondary operations
was much higher in the patients who were treated with Ender pins, and a
considerably higher number of those patients had loss of fixation. The use
of Ender pins that were too long and a history of a fracture before the
operation in which Ender pins were used were statistically significant
predictors of secondary operations.
