Abstract: Objective To compare the surgical efficacy between INTERTAN intramedullary nail and sliding hip screw in treating intertrochanteric or subtrochanteric fracture of old people. Methods From Jan 2010 to Jan 2012, 120 patients with Intertrochanteric or subtrochanteric Fractures were treated by INTERTAN intramedullary nail ( n=67) and sliding hip screw (n=53). Operation time, bleeding volume, amount of drainage, visual analogue scale (VAS) pain score, Harris hip score, SF-36 score and complications were recorded at each time points. Results Among all the patients, 111 patients (INTERTAN group: 64 cases; DHS group: 47 cases) were followed up for more than 1 year successfully. Bleeding volume and amount of drainage in INTERTAN group were larger than in DHS group. VAS score in INTERTAN group 3 days after operation was better than in DHS group, and there was no difference between the two groups 3 and 12 months after operation. There was no difference between the two groups in operation time, Harris hip score, SF-36 score and complications during the time of follow-up. Conclusion INTERTAN nails and sliding hip screws are similar in terms of pain, function, and comlications rates in treating intertrochanteric or subtrochanteric fractures.

Key words: INTERTAN intramedullary nail, Sliding hip screw fracture, Intertrochanteric fracture, Subtrochanteric fracture
