[Case-control study on InterTan intramedullary nail in treating coronal femoral intertrochanteric fracture in elderly].

OBJECTIVE

To compare clinical effect of closed reduction and limited open reduction and internal fixation with InterTan intramedullary nail in treating elderly patients with coronal femoral intertrochanteric fracture.

METHODS

From January 2013 to December 2015, 23 elderly patients with coronal femoral intertrochanteric fracture were divided into two groups according to different ways of reduction to be retrospectively analyzed. There were 12 cases with closed reduction and internal fixation with InterTan intramedullary nail group (closed reduction group), including 7 males and 5 females with an average age of(63.6±12.1) years old; while 11 cases with limited open reduction and internal fixation with InterTan intramedullary nail group(limited reduction group), including 6 males and 5 females with an average of (60.8±12.5) years old. Intraoperative blood loss, fluoroscopy, operative time, postoperative complications, hospital stays and bone healing time were observed and compared. Harris score of hip joint at 1 year after operation was compared between two groups.

RESULTS

The incisions between two groups were healed well at stage I, and no complications occurred. One case was died during following-up, and 22 cases were obtained following-up from 12 to 23 months with an average of 13.6 months. There were significant difference in operative time, intraoperative blood loss and fluoroscopy(P<0.05); while no difference in hospital stays, postoperative complications(P>0.05). Harris score at 1 year after operation in open reduction group was(83.9±8.9), and(83.4±9.1) in closed reduction group without significant difference between two groups(P>0.05).

CONCLUSIONS

Closed reduction and limited open reduction with InterTan intramedullary nail internal fixation for the treatment of intertrochanteric femoral coronal fractures could achieve good clinical effects, the former to receive more radiation dose, with less trauma;while the latter has disadvantages of long blood bleeding and operative time, but could obtain high quality of reduction.
