Abstract

Abstract:

BACKGROUND: There is no unified method for treatment of intertrochanteric fracture. Previous dynamic hip screw fixation has some shortcomings, and is gradually replaced by intramedullary nail fixation. interTan is a compression interlocking intramedullary nail designed by Smith Nephew in USA according the characteristics of intertrochanteric fracture. Unique design of pressurized screw thread has controllable linear pressure. Moreover, it has the stability of Z-effect anti-rotation.
OBJECTIVE: To analyze the clinical therapeutic effects and superiority of interTan compression interlocking intramedullary nail for intertrochanteric fracture.
METHODS: A total of 60 patients with intertrochanteric fracture undergoing interTan compression interlocking intramedullary nail in the Department of Orthopedics, Beijing Chaoyang Emergency Rescue Center from January 2011 to December 2012 were enrolled in the experimental group. A total of 60 patients with intertrochanteric fractures receiving dynamic hip screw fixation in the Department of Orthopedics, Beijing Chaoyang Emergency Rescue Center from January 2009 to December 2010 were enrolled in the control group.
RESULTS AND CONCLUSION: Peri-operative bleeding volume, postoperative ambulation time, numerical rating scale score, radiographic healing time and weight-bearing time in the experimental group were lower than those of control group. At 3, 6 months and 1 year after fixation, Harris score and hospital for special surgery knee score were higher in the experimental group than in the control group. These data indicated that compared with dynamic hip screw, interTan compression interlocking intramedullary nail has unique stability due to its design. Internal fixation can reduce operation trauma, promote fracture healing and improve joint function, and exhibit good clinical therapeutic effects for intertrochanteric fractures.
