A 70-year-old patient came with complaints of left hip pain for 4 days which occurred after sustaining a fall from height.
The pain was sudden in onset progressive in nature. The pain was sharp, shooting in nature which increased on movement and decreased on rest.

CLASSIFICATION OF INTERTROCHANTERIC FRACTURE: Intertrochanteric (IT) fractures are commonly witnessed.
The classification of the IT fractures is important as it helps us choose from an array of implants for a better outcome and management protocols.
Few classifications focus on the anatomical pattern (Evans; Ramadiers; Decoulx and Lavarde) while others on maintaining reduction of various types (Jensen’s modification of Evan’s Ender, Tronzo , AO). 
Intertrochanteric fracture is the most common of the extracapsular hip fractures many of which may be associated with a varus deformity. Comminuted fractures may occur which may also manifest as separate fragments of either one trochanter or both of the lesser and greater trochanter.
Fracture Healing occurs by callous formation and can occur by primary or secondary union.
Healing by Primary Union: here the ends of the fractures are approximated by application of surgical clamps, metal plates. Herein the bony union occurs with the formation of medullary callous without the formation of periosteal callous.
Healing by Secondary Union: It is more common and occurs upon application of plaster to the broken bone, the steps involved are:
Procallous Formation: Hematoma that has occurred due to bleeding of blood vessels has blood and fibrin which forms granulation tissue. Local inflammatory response occurs which clears away the dead tissue and debris. Ingrowth of the granulation tissue occurs causing formation of callous composed of bony and cartilaginous material.
Osseous Callous Formation: The procallous formed earlier acts as a scaffolding over which forms the osseous callous, the woven bone is taken over by formation of lamellar bone.
Osteoblastic and osteoclastic activity occurs in the bone helping it remodel in such a way that after sometime the new bone formed looks indistinguishable from the normal bone.
