Subdural haematoma

Patient: Fall, No LOC
CT-findings: Small dense left subdural haematoma, mass effect with sulcal obliteration with subfalcine herniation.

Findings in subdural hematoma:
  1. 90% supratentorial
  2. cresentic shape
  3. cross suture lines.
  4. does not cross dural reflections
  5. acute - hyperdense, chronic - hypodense.

Definition of dynamisation

Dynamisation: The mechanical load transferred across a fracture locus can be increased, at a certain healing stage, in order to enhance bone formation, or to promote "maturation" of the healing tissues. An example would be the reduction in stiffness of an external fixation, either by loosening some clamps, reducing the number of pins, or moving the tubular construct further from the bone. Early dynamisation, i.e. before solid bridging of the bone, can result in stimulation of callus formation. The value of later dynamisation is debatable.

Pin fixators

Advantage: routine work, stabilises diaphyseal fractures, good wound access.

Disadvantages: requires reduction, limited angulatory and rotatory deformities, no axial loading permitted, high incidence of union or non-union, angulatory deformities in bone lengthing, no progressive correction allowed.

  • Pin: Schanz screw/half-pin,Steinmann pin
  • Clamp
  • Central body
  • Compression and distraction system

Guilty conscience

Hmm I know I'll pass med school. I know I'll make a good doctor given time. But I dont feel confident enough to excel in my current exams. And if I dont, the one overwhelming feeling I would have is guilt towards my parents...then I'll hear my mummy say "Its alright you tried your best". Strange how this guilt far weighs any guilt I have towards my own inadequecies. Gotta get in my head that God controls everything that I'm merely riding a roller coaster. Arh.....Funny how though people all think I know my stuff....work!
