Summary Intertrochanteric Fractures are common extracapsular fractures of the proximal femur at the level of the greater and lesser trochanter that are most commonly seen following ground-level falls in the elderly population. Diagnosis is made with orthogonal radiographs of the hip. MRI is most helpful to evaluate occult hip fractures. Treatment is generally operative with sliding hip screw versus cephalomedullary nail depending on fracture stability. Epidemiology Incidence account for ~50% of hip fractures 150,000 intertrochanteric fractures per year in US 500 per 100,000 population per year for elderly female 200 per 100,000 population per year for elderly male Demographics age average ~80 years old typically older age than femoral neck fractures female: male ratio between 2:1 and 8:1 Risk factors proximal humerus fractures increase risk of hip fracture for 1 year osteoporosis advancing age increased number of comorbidities increased dependency with ADLs Etiology Pathophysiology mechanism elderly low energy falls in osteoporotic patients

and also comprises calcar Classification Stability most commonly used and reliable classification two types stable definition intact posteromedial cortex clinical significance will resist medial compressive loads once reduced unstable definition fracture will collapse into varus or shaft will displace medially examples large or comminuted posteromedial cortex i.e. lesser trochanteric fragment reverse obliquity or transtrochanteric fracture line extending from medial cortex out through lateral cortex subtrochanteric extension other considerations lateral wall thickness measured from 3 cm distal from innominate tubercle at 135 degrees to the fracture site <20.5 mm suggest risk of postoperative lateral wall fracture should be treated with cephalomedullary nail (CMN) rather than sliding hip screw (SHS) key role in stabilizing proximal femur by providing lateral buttress AO/OTA Classification 31A -A1 peritrochanteric simple two part intact lateral cortex 31A-A2 pertrochanteric with separate posteromedial fragment intact lateral cortex 31A-A3 fracture extends through lateral and medial cortex Evans classification (based on post-reduction stability) Stable fracture posteromedial cortex intact or minimal comminution able to resist compressive loads Unstable fracture greater comminution of posteromedial cortex can be converted to a stable pattern if medial cortical opposition obtained Reverse obliquity unstable due to medial displacement of femoral shaft due to adductors Presentation History mechanism of injury low-energy most common in elderly higher-energy may be
