Abstract
Subtrochanteric fractures are a subtype of proximal femur fractures found between the lesser trochanter and 5 cm distal to it. Due to its muscle insertions, the subtrochanteric region of the femur is susceptible to several deforming stresses and is an area of high stress concentration. Due to the prevalence of cortical bone, the subtrochanteric area has a more fragile vascularization than the trans-trochanteric zone, making it more difficult to consolidate fractures. Implant-related problems and fracture non-union are found to be prevalent in proximal femur fractures with a high reoperation rate. The bimodal occurrence of subtrochanteric fracture in young and elderly patients poses a problem when selecting the optimal implant to restore function with the lowest risk of surgical and medical problems.
The undamaged medial and lateral cortex under the lesser trochanter offers a buffer to fracture impaction following fixation, hence preventing its collapse. The degree of comminution of the posteromedial cortex and osteoporotic bone increases the degree of instability. Increased comminution reduces axial loading support via cortical contact. A fracture is rendered unstable if any of these cortical areas is deficient.
Implant fixation aims to produce stable reduction and fixing of the fracture, allowing for rapid mobilization. The orthopaedic community continues to discuss the reasoning for the design of extramedullary fixation for subtrochanteric fractures of the femur. Subtrochanteric fractures have been treated using intramedullary devices (SHS, condylar blade plate, and proximal femoral locking plate) rather than extramedullary implants (SHS, condylar blade plate, and proximal femoral locking plate) over the last 25 years. This chapter discusses the reasons for and suggestions for implant changes, as well as the implant of choice currently in use.
