Pneumothorax
Pneumothorax, commonly abbreviated to PTX, (plural: pneumothoraces) refers to the presence of gas (often air) in the pleural space. When this collection of gas constantly enlarges with resulting compression of mediastinal structures, it can be life-threatening and is known as a tension pneumotho...

Essex-Lopresti fracture-dislocation
Essex-Lopresti fracture-dislocation is characterized by a fracture of the radial head, dislocation of the distal radioulnar joint and rupture of the antebrachial interosseous membrane 3.
Epidemiology
As little as 20% of Essex-Lopresti fracture-dislocations are recognized at the time of initial...

CT cystography
CT cystography is a variation of the traditional fluoroscopic cystogram. Instead of anterograde opacification of the urinary collecting system (as with CT urography), contrast is instilled retrograde into the patient's bladder, and then the pelvis is imaged with CT.
Indications
suspected bladd...

Brachial plexus injuries
Brachial plexus injuries are a spectrum of upper limb neurological deficits secondary to partial or complete injury to the brachial plexus, which provides the nerve supply of upper limb muscles.
Clinical presentation
Trauma, usually by motor vehicle accidents, involves severe traction on the ...

Lateral humeral condyle fracture
Lateral humeral condyle fractures also referred to simply as lateral condyle fractures (in the appropriate context), are relatively common elbow fractures that predominantly occur in children. They may be subtle but are hugely important to diagnose promptly because if they are missed, they tend ...

Physiological pelvic intraperitoneal fluid
Physiological pelvic intraperitoneal fluid refers to the presence of a small volume of free fluid in the pelvis, particularly the pouch of Douglas. It occurs in young females of reproductive age and can be a mimic of traumatic free fluid in abdominal trauma.
Unfortunately, pelvic free fluid may...

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

Penetrating thoracic trauma
Penetrating thoracic trauma, namely gunshot and stab injuries, vary widely in incidence globally but nevertheless result in high mortality and serious morbidity. CT is the modality of choice in imaging these patients and can reduce the need for surgical exploration.
Pathology
Penetrating thor...
Article
Penetrating abdominopelvic trauma
Penetrating abdominopelvic trauma usually occurs in the setting of gunshot and stab injuries and is associated with high morbidity and mortality. CT is the modality of choice in imaging if the patient is stable enough before surgery. The most common injuries include small bowel, large bowel, liv...
Article
Lisfranc injury
Lisfranc injuries, also called Lisfranc fracture-dislocations, are the most common type of dislocation involving the foot and correspond to the dislocation of the articulation of the tarsus with the metatarsal bases.
Pathology
Anatomy
The Lisfranc joint articulates the tarsus with the metatar...
Article
Diffuse axonal injury (grading)
Grading of diffuse axonal injury due to trauma is described according to the anatomic distribution of injury. Contrary to the implication of the word "diffuse," diffuse axonal injury has a topological predilection for focal involvement of certain sites in the brain. These sites, in turn, vary in...
Article
Trauma
The term trauma (plural: traumas) or traumatic injury refers to damage or harm of sudden onset caused by external factors or forces requiring medical attention.

Article
Avulsion fractures of the knee
Avulsion fractures of the knee are numerous due to the many ligaments and tendons inserting around this joint. They include 1:
anterior cruciate ligament avulsion fracture
posterior cruciate ligament avulsion fracture
avulsion of the medial collateral ligament
origin of MCL avulsion fracture...

Pneumorrhachis
Pneumorrhachis refers to the presence of gas within the spinal canal (either intra- or extradural). It is rare.
Clinical presentation
Patients can often be asymptomatic 3.
Pathology
Etiology
Pneumorrhachis can result from a number of causes:
trauma (traumatic pneumorrhachis): can occur in ...
Article
Knee (horizontal beam lateral view)
The horizontal beam lateral view (cross-table lateral) is an orthogonal view of the AP view of the knee requiring little to no patient movement and is hence the lateral projection of choice for acute knee injuries.
Indications
This view is the ideal projection to assess the presence of knee jo...

Modified Memphis criteria for blunt cerebrovascular injury
The modified Memphis criteria are a set of screening criteria for blunt cerebrovascular injury (BCVI) in trauma. The presence of one or more of these criteria makes necessary a complementary CTA or DSA study to exclude a BCVI.
The screening protocol criteria for BCVI are:
base of skull fractur...
Article
High-velocity penetrating brain injury
High-velocity penetrating brain injuries, in practical terms most often due to cranial gunshot injuries, are a form of penetrating traumatic brain injuries, which are much less common than blunt traumatic brain injuries and distinguished from low-velocity penetrating brain injuries (such as stab...
Article
Finger pulley injury
Finger pulley injuries can occur at any one of the five flexor tendon pulleys of the fingers, but most commonly affects the A2 pulley.
Clinical presentation
These are overwhelmingly the result of a discrete trauma occurring with the hand in a finger grip position. They are most frequently see...
Article
Chalk stick fracture
Chalk stick, also known as carrot stick fractures, are fractures of the fused spine, classically seen in ankylosing spondylitis.
Terminology
Some authors define the chalk stick fracture as a fracture through a Pagetoid long bone (see Paget disease) 3.
Pathology
They usually occur through the...
