In recent years, with the aging of the population, the incidence of proximal femoral fractures has been increasing year by year. According to incomplete statistics, there were approximately 1.66 million osteoporosis related hip fracture patients worldwide in 1990, and this number is expected to reach 6.26 million by 2050.
Elderly patients with proximal femoral fractures face a high mortality rate due to physical conditions and various complications. Among them, the mortality rate of intertrochanteric fractures is as high as 15%–20%.
Intertrochanteric fracture is a common type of hip fracture in elderly patients, especially those with osteoporosis. In contrast, young patients mostly suffer from high-energy traumatic injuries.
Surgical treatment of intertrochanteric fractures includes various options:
Extramedullary fixation, such as dynamic hip screw (DHS), dynamic condylar screw, etc.
Intramedullary fixation, such as Gamma Nail, Proximal Femur Nail (PFN), proximal femoral nail antirotation (PFNA), Intertan, and so on.
Today we want to introduce the Interlocking Intramedullary Nail technology.
The greatest advantage of Titanium Femoral Nail lies in their intramedullary position, which provides mechanical intramedullary support and prevents excessive collapse, and this is almost independent of whether the lateral cortex has supportive capacity.
In addition, the intramedullary location with a shortened moment arm theoretically offers biomechanical advantages and can reduce the incidence of fatigue failure of internal fixation devices. Meanwhile, the intramedullary fixation system is less prone to coxa vara even when the medial cortex loses support. Therefore, separate reduction and fixation for displaced lesser trochanter fractures are generally not recommended.
PFNA Intramedullary Nail
The head nail of PFNA adopts a spiral blade locking mechanism.The blade features a large surface area and a gradually increasing core diameter.When impacted into the bone, the spiral blade can self-rotate, exerting a compression effect on the bone stock, thereby preserving bone mass and achieving close contact between the blade and the bone.
This enhances the anchoring strength of the spiral blade. Meanwhile, it provides anti-rotation and angular stability, which can reduce the incidence of deformities such as coxa vara.
Interzan Intramedullary Nail
Intertan is a new generation of Intramedullary Femoral Nail specifically designed for intertrochanteric femoral fractures.Its proximal cross-section is trapezoidal, imitating the structure of the proximal part of joint prostheses,allowing the nail to better match the medullary cavity and conform to the biomechanical characteristics of the proximal femur.
Meanwhile, Intertan Femoral Nail can maximally preserve the bone stock of the lateral wall of the greater trochanter during surgeryand enhance the ability to resist rotation and contralateral stress.
Both types of intramedullary nails adopt a distal forked design, which can more effectively disperse stress. The distal locking screws are positioned relatively far from the distal end of the main nail,thereby reducing the risk of distal femoral fractures.
