Overview
- What this topic teaches you
Anatomy of the proximal ulna
- The big picture: why proximal ulna fractures matter
- The half-moon notch and the goals of treatment
- The elbow's extension engine: the triceps
- How triceps efficiency changes with elbow angle
- Why triceps power varies with elbow position
- The coronoid process: a small beak with big jobs
- Coronoid process anatomy and soft-tissue attachments
- Notch length and opening angle set elbow stability
- Notch length, opening angle and elbow stability
- How much the bony notch contributes to stability
- The shape of the notch resists side-to-side tilt
- Fixation methods: what works and what was abandoned
- Tension band versus plate: choosing the tool
- Three fixation strategies for olecranon fractures
- A biomechanical caution about tension bands
How proximal ulna fractures happen
- Direct violence: a blow to the point of the elbow
- Olecranon fracture-dislocation from a direct blow
- Elbow position steers the direct-injury pattern
- Indirect violence: force travelling up from the hand
- Posteromedial rotation injury of the elbow
- Posteromedial rotation injury mechanism
Classifying the fractures
- Schatzker classification of olecranon fractures
- Reading the Schatzker types
- Schatzker classification of olecranon fractures
- Regan and Morrey classification of coronoid fractures
- Regan and Morrey classification of coronoid fractures
- O'Driscoll classification: location, not just size
- O'Driscoll classification of coronoid fractures
Assessing the injured elbow
- Clinical assessment at the bedside
- Do not miss the neighbours: nerves and the forearm
- Imaging: X-ray first, then CT for the hidden pieces
- Imaging an easily missed anteromedial coronoid fracture
- Why CT earns its place here
Surgical treatment of the olecranon
- When to operate and what surgery aims for
- Positioning and preparation
- Patient positioning for olecranon surgery
- Incision and surgical approach
- Posterior elbow incision
- Exposing and inspecting the olecranon fracture
- Matching fixation to Schatzker type (A-C)
- Fixation for the harder patterns (D, E, F)
- The Kirschner-wire tension band, step by step
- Kirschner-wire and tension band fixation technique
- Kirschner-wire and tension band fixation, continued
- Finishing the tension band cleanly
- Tension band fixation, Schatzker C case
- Wire-tightening pearls and common failures
- Correct even tightening of tension-band wires
- The elderly, osteoporotic olecranon
- Fragment excision and triceps reconstruction principle
- Plate and screw fixation technique
- Plate-screw fixation of a proximal ulnar fracture
- Plate-screw fixation, case example
- Fixing butterfly and comminuted patterns
- Tension band and plate for a butterfly fragment
- Bridging plate for badly comminuted fractures
- Bridging plate for a comminuted olecranon fracture
- Schatzker D fracture with anterior dislocation, fixed
- Postoperative care and rehabilitation
Surgery for the coronoid process
- Regan-Morrey type I: often conservative
- Regan-Morrey type II and III
- O'Driscoll type II: the anteromedial trap
- Choosing the surgical approach (1)
- Choosing the surgical approach (2)
- Olecranon plus coronoid: sequence is everything
- Olecranon fracture with coronoid fracture, case
- Olecranon with coronoid fracture, follow-up
- Anteromedial coronoid fracture with LCL rupture
- Anteromedial coronoid plate fixation
- Anteromedial coronoid repair, case
Complications and prevention
- Complications of the K-wire tension band
- Why plain intramedullary nails go wrong here
- Why an intramedullary nail malaligns the proximal ulna
- Persistent elbow instability
- Elbow complex fracture: coronoid and radial head
- Heterotopic ossification
- Heterotopic ossification after complex elbow fixation
