Abstract

Purpose
To retrospectively compare the fixation methods for reattaching a trochanteric fragment in a pertrochanteric fracture treated with bipolar hemiarthroplasty. Materials and methods: Forty cases of an unstable femur pertrochanteric fracture were analyzed and followed up for average of 19(6~40) months. There were 18 cases fixed with tension band wiring (group 1), 7 cases treated using modified tension band wiring with K-wires (group 2) and 15 cases treated with the GTRD (Greater Trochanteric Reattachment Device) (group 3). Result: Group 1 was treated with simple a surgical procedure and the results were good. The second group had firm fixation postoperatively but required additional surgery in two cases to remove the K-wires because of wire migration after ambulation. Group 3 had relatively good results but required more dissection and a longer operating time. Conclusion: Tension band wiring or GTRD are good fixation methods for reattaching trochanteric fragments in pertrochanteric fractures. Moreover, tension band wiring is recommended for old osteoporotic patients due to a simple procedure and firm fixation. The use of modified tension band wiring using K-wire or a Steinmann-pin should not be used due to the possibility of distant migration.
