Study Notes
Small Bowel Obstruction
- Occurrence: More common
- Causes: Adhesions, hernia, malignancy, diverticular disease, volvulus (twisting of the bowel)
- Symptoms: Abdominal pain, nausea, vomiting, distention
- Imaging: Abdominal X-ray (AXR) can be used as a screening tool, often replaced by CT
- Appearance on AXR (CT): Dilated loops of bowel, well-defined, width exceeds the size of the pacemaker
Extremities
Fractures
- Definition: Disruption of bone caused by mechanical forces
- Appearance on X-ray: Radiolucent line crossing the bone, disrupting the cortical outline
- Soft tissue signs: Joint effusion, swelling and oedema
Types of Fractures
- Greenstick: Incomplete fracture, common in children
- Torus: Buckling of the bone, common in children
- Colles: Fracture of the distal radius, causes "Dinner fork deformity"
- Boxers: Fracture of the 5th metacarpal bone
- Avulsion: Fracture caused by forceful pulling of a tendon
- Monteggia: Fracture of the ulna, often accompanied by dislocation of the radial head
- Galeazzi: Fracture of the radius, often accompanied by dislocation of the distal radioulnar joint
Treatment
- Conservative: Casting, splinting, physical therapy
- Closed reduction: Manual manipulation to realign the bone
- Open reduction/Internal fixation (ORIF): Surgical procedure involving bone fixation with plates or screws
- External fixation: External frame attached to the bone to stabilize it
Osteoarthritis (OA)
- Definition: Degenerative joint disease characterized by cartilage breakdown and bone spurs
- Appearance on X-ray: Severe degenerative change, irregular bone formation
Summary
- Chest: Pneumothorax, Pleural effusion, Pneumonia
- Abdomen: Kidney Stones (Urolithiasis), Gallstones (Cholelithiasis), Bowel obstruction
- Clavicle: Fractures
- Hand/Wrist: Fractures, Osteoarthritis
Imaging Anatomy
- Key concepts: Specificity is important (left/right, aspect), using correct terms, identifying bony and soft tissue structures
- Chest: Sternum, clavicle, scapula, ribs, lungs
- Abdomen: Diaphragm, liver, stomach, kidneys, psoas muscle, bladder
- Clavicle: Medial (sternoclavicular), lateral (acromioclavicular)
- Wrist/Hand: Carpal bones (scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, hamate), metacarpals, phalanges
Imaging Pathology
- Key concept: Relating radiographic appearances to potential pathologies
- Chest: Pneumothorax, pleural effusion, pneumonia
- Abdomen: Kidney stones, gallstones, bowel obstruction
