Study Notes
Reading an Image
- IDS (Image Detail Score): Reflects how well body positioning penetrates contrast artifacts.
- Compare to previous studies, noting identification and date.
- The correct view depends on the direction of waves.
- Position the area of interest closest to the plate for clarity.
- PA (Posterior-Anterior): Preferred for heart and chest X-rays; provides better heart definition.
- AP (Anterior-Posterior): If checking vertebrae is desired
- Note:
- The white rays project through the body to the white plate.
- The item directly on the plate is the most visible.
- Objects further from the plate appear larger, and objects closer appear the correct size and darker.
- Know patient sides for reference: Left (L) and Right (R)
Radial and Ulnar Fractures
- Monteggia Fracture Dislocation aka Night-Stick Injury: Fracture of the ulna with radial head dislocation.
- Occurs in children receiving a blow to the forearm while trying to protect themselves; a visible deformity is common.
- Impacts the Posterior Interosseous Nerve (PIN), potentially damaging the radial nerve, affecting thumb & wrist extensors.
- X-rays include elbow+distal views AP and lateral axes.
- Usually, dislocation of radial head is anterior.
- Galeazzi Fracture Dislocation: Fracture of the distal radius with dislocation or subluxation of the distal radio-ulnar joint (DRUJ) at wrist +AP/LAT X-Rays.
- FOOSH is a MOI & presents with wrist deformity.
- Distal radius fracture + dislocation or subluxation at the wrist.
- Radius = ulner head at the wrist.
Wrist Anatomy
- Wrist & Hands: Proximal is proximal to the Distal row of carpals
- Acronym: "Some Lovers Try Positions That They Can't Handle"
- Lateral vs. PA: Key anatomical structures include radial styloid, ulna styloid etc
- Lunate = Saucer, Capitate = Cup
Wrist series (X-rays)
- PA hands for hand series.
- Oblique
- Lateral views are essential.
- PA oblique hand demonstrates joint spaces
- AP oblique hand captures ball-catcher’s position;
-
PA oblique highlights **Metacarpals**
Wrist Fractures
- Colles' Fracture: Distal radius fracture with dorsal angulation; the most common wrist fracture.
- Result of FOOSH (falling on outstretched hand), common in older women with osteoporosis.
- Leads to a "dinner fork" deformity.
- X-rays show distal radius fracture with dorsal angulation.
- Smith's Fracture: Distal radius fracture with palmar angulation, the opposite of Colles' fracture.
- Less dangerous because there are Nerovascular structures.
- Results from falling backward.
- Often seen in young male patients.
- Leads to “garden space” deformity.
- Barton's Fracture: Intraarticular fracture involving the distal radius.
- Volar: Maintains relationship with carpus & both and displaced proximally.
Scaphoid Fractures
- FOOSH injury that causes anatomic snuff box tenderness.
- The most fractured carpal bone, with fractures usually occurring at the waist.
- Risk of avascular necrosis due to distal-to-proximal blood supply.
- X-rays include PA, lateral, and oblique views.
- Often missed on X-ray, consider MRI/bone scintigraphy if suspected.
- Manage by putting a thumb on the spica splint
- Goes on hand & Then Back
- Can't always be seen; Need to be tested for
- Need to be check with both
Wrist Dislocations
- Wrist dislocations are caused by FOOSH with ulnar deviation and dorsiflexion (hyperextension).
- Always watch for median nerve injury, radial and ulnar fractures.
- Best diagnosed with PA & lateral radiographs.
- Lunate cup is used to refer to capitate and saucer
Carpal Dislocations
- Perilunate Dislocation: Dorsal dislocation of the capitate bone (displaced laterally).
- Best diagnosed with the lateral view
- Capitate and phalanx are not in line, the lunate and the radius ulna are.
- Dont see spaces should in space
Other Wrist dislocations
- Lunate Dislocation.
- Lunate: trianglular view Due anteriorerly
Intra articular fracturess
- Hand xrays histories, where is the following Bennetts VS. Rolands
- Fractures for Both bennetts And Rolansid
- Look for Other Fx's injuries, Axial, Loading on Palm, Or fully Flexed
- Bennett's Fracture
- single intraarticular fracture base one metacarpal to see if you can distingis that
