Intramedullary nailing is an internal fixation technique mainly used for the surgical management of long bone diaphyseal fractures and more recently, also in metaphyseal and periarticular fractures.
Indications
Indications of intramedullary nailing are the following 1,2:
extra-capsular proxim...

Pelvis (outlet view)
The anteroposterior outlet view is a specialized view part of a pelvic series examining the iliac crest, sacrum, proximal femur, pubis, ischium and the great pelvic ring.
Indications
The outlet view is of considerable importance in the management of severely injured patients presenting to emer...
Article
Coxa vara
Coxa vara describes a deformity of the hip where the femoral neck-shaft angle is decreased, usually defined as less than 120 degrees.
Pathology
It can be congenital or acquired. The common mechanism in congenital cases is a failure of medial growth of the physeal plate 3.

Cam morphology (femoroacetabular impingement)
Cam morphology refers to an abnormal morphology of the femoral head-neck junction interlinked with an osseous asphericity of the femoral head. It is one possible cause of femoroacetabular impingement (FAI).
Terminology
Cam morphology is also commonly referred to as 'cam deformity', 'cam lesion...
Article
Hip (lateral view)
The lateral hip view is a radiographic projection assessing the relationship of the femoral head to the acetabulum.
Indications
This view assesses the hip joint for any potential fractures, dislocations, bone lesions or degenerative diseases (i.e. suspected osteoarthritis of the hip) in an ort...

Atypical femoral fracture
Atypical femoral fractures, also known as bisphosphonate-related proximal femoral fractures, are an example of insufficiency fractures, although the direct causative link remains somewhat controversial 2. The atypical fracture pattern occurs in the femur shaft and may be unilateral or bilateral....
Article
CT hip (protocol)
The CT hip protocol serves as an examination for the evaluation of the hip joint. It is often performed as a non-contrast study. However, it can be combined with a CT arthrogram for the evaluation of chondral and/or labral tears or a femoral neck version scan.
Note: This article aims to frame a...
Article
Dual-energy x-ray absorptiometry
Dual-energy x-ray absorptiometry (DEXA or DXA) is a technique used to aid in the diagnosis of osteopenia and osteoporosis.
Radiographic features
Values are calculated for the lumbar vertebrae and femur preferentially, and if one of those sites is not suitable (e.g. artifact, patient mobility)...
Article
Trochanteric fracture
A trochanteric fracture is a fracture involving the greater and/or lesser trochanters of the femur.
Classification
Fractures in these regions can be classified as:
intertrochanteric fracture
pertrochanteric: intertrochanteric, involving both trochanters
subtrochanteric fracture

Article
Proximal femoral fractures
Proximal femoral fractures are a subset of fractures that occur in the hip region. They tend to occur in older patients, and in those who have osteoporosis. In this group of patients, the fracture is usually the result of low-impact trauma although, in younger patients they are usually victims o...
Article
Osteochondroma
Osteochondromas are a relatively common imaging finding, accounting for 10-15% of all bone tumors and ~35% of all benign bone tumors. Although usually thought of as a benign bone tumor, they may be thought of as a developmental anomaly. They are frequently asymptomatic and have very low malignan...
