Olecranon Fracture Flashcards
In which age group are olecranon fractures more common
Older people following low energy indirect injuries.
What does the olecranon articulate with
Trochlea of the distal humerus
Which muscles insert into the olecranon
Triceps
How do olecranon fractures usually occur in older Patients
Indirect trauma - FOOSH which results in a sudden pull of the triceps and brachialis muscles
How do olecranon fractures occur in younger patients
Associated with direct trauma that are high energy injuries
Normally associated with other forearm injuries
What are the clinical features of olecranon fractures
History of FOOSH Elbow pain Swelling Lack of mobility Tenderness Inability to extend elbow
Shoulder and wrist should be examined aswell ( joint above and below)
Which lab tests must be carried out when admitting a patient
Routine bloods including clotting screen and group and save
What is the initial imaging investigations
Plain AP and lateral radiographs of the joint affect and joint above and below too
CT if complicated fracture
What are some classification systems used for olecranon fractures
Mayo classification
Schatzker classification
How do you resuscitate patients prior to management
Adequate analgesia
When is non operative management of olecranon fractures indicated
Degree of displacement is less than 2mm
What is the non operative management
Immobilisation in 60-90 degrees elbow flexion and early introduction to movement in 1-2 weeks following fracture
When is operative management indicated
Displacement of 2mm or more
what is the operative management
Tension band wiring - if fracture is proximal to coranoid process
Olecranon plating - if fracture is distal to the coranoid process
