According to Tronzo and Evans classification, there were 2 cases of type, 9 of type, 7 of type, and 1 of type. Nine patients were of grade 3 or below according to Singh grading (obvious osteoporosis). All patients were treated with INTERTAN. The internal fixation time, Harris hip score, fracture healing and perioperative complications were recorded. All 19 patients were followed up for 6.2 months (ranging 58 months). The average surgical time was 65 minutes (ranging 45126 minutes). A total of 13 patients restored to their prefracture level. The Harris score at the final follow up was 77.6 scores (ranging 30-92), including 5 cases of excellent, 9 of good, 3 of fair, 2 of poor with the good and excellent rate of 74%. The pain in 95% of the patients was relieved over a short period of time after surgery. All fractures healed on the radiographs within the average of 2.6 months (ranging 24 months). There was one collapse of the neck, no varus malposition, femoral shaft fracture, or implant failures were found. The new intertrochanteric antegrade nail of INTERTAN can be used to treat various femoral intertrochanteric fractures with good clinical outcomes, high union rate, and rare complications.
