A comparative biomechanical study of proximal femoral nail (InterTAN) and proximal femoral nail antirotation for intertrochanteric fractures

Abstract

Comparison of the treatment of intertrochanteric fractures with InterTAN and PFNA internal fixation showed that the InterTAN yielded improvement relative to the PFNA. InterTAN has a firmer and biomechanically superior performance and is therefore an ideal internal fixation method for treating intertrochanteric fractures. Additional research in osteopenic bone is necessary to comprehensively characterize the effects of the design enhancements of these two implants.

Comparison of Two Types of Proximal Femoral Nails in the Treatment of Intertrochanteric Femur Fractures

“…[19] In the biomechanical study of Huang et al, femoral strength, stability, and bearing capacity have been higher in the InterTAN group than in the PFNA group. [22] Lin has reported that the use of PFNs with two lag screws is effective to treat AO OTA A1-A2-A3 ITF. [17] In the study by Erturer et al, union has been achieved in all thirty-two patients treated using Profin PFNs, although two patients have undergone revision surgeries because of poor fracture reduction.…”

Prospective randomised controlled trial of an intramedullary nail versus a sliding hip screw for intertrochanteric fractures of the femur

“…The use of cephalomedullary nails has overtaken the use of sliding hip screws in the treatment of intertrochanteric fractures during the past decade [5,15,17,26]. This trend seems unjustified, as extensive meta-analyses of randomised trials fail to demonstrate the relative benefit of intramedullary devices [40].…”

Loss of offset after pertrochanteric hip fractures affects hip function one year after surgery with a short intramedullary nail. A prospective cohort study

“…This may be due to better early pain relief and mobilisation, but there is also a possibility of the compression being less and the offset thus being less affected. Even without additional components improvements could possibly be achieved through better perioperative fracture reduction [31,32].…”
