A 62-year-old woman with osteoporosis presents to the emergency department 2 hours after a fall on an outstretched hand. Clinical examination reveals a 'dinner fork' deformity of the right wrist with dorsal angulation. X-rays confirm a Colles fracture with dorsal displacement and angulation. The hand is warm, well-perfused, and sensations are intact. What is the most appropriate immediate next step in management?

Explanation

## Clinical Scenario Analysis This is a **displaced Colles fracture** (dorsal angulation and displacement) in an elderly patient with osteoporosis, presenting acutely within the therapeutic window for reduction. ## Key Point: **Closed reduction is the gold standard for most Colles fractures**, even when displaced, provided there is no neurovascular compromise, open fracture, or intra-articular involvement that mandates surgery. ## Management Algorithm ```mermaid flowchart TD A[Displaced Colles Fracture]:::outcome --> B{Neurovascular intact?}:::decision B -->|Yes| C{Open fracture or severe comminution?}:::decision B -->|No| D[Urgent vascular/nerve assessment]:::urgent C -->|No| E[Closed reduction + immobilization]:::action C -->|Yes| F[ORIF consideration]:::action E --> G[Post-reduction X-ray + cast]:::action G --> H[Review at 1-2 weeks]:::action ``` ## Why Closed Reduction? 1. **Neurovascular status intact** — no emergency indication for immediate surgery 2. **Time-sensitive window** — reduction within 6–8 hours optimizes soft-tissue healing and reduces redisplacement 3. **Age and bone quality** — osteoporotic bone in elderly patients often heals well with conservative management; ORIF is reserved for specific indications (intra-articular fractures, severe comminution, failed reduction) 4. **Anesthesia** — adequate analgesia (hematoma block, procedural sedation, or regional block) is essential before reduction ## High-Yield: **Colles fractures are reduced closed unless:** - Open fracture - Neurovascular compromise - Intra-articular extension with >2 mm step-off - Severe comminution (>3 fragments) in young, active patients - Failed closed reduction (loss of reduction on follow-up) ## Clinical Pearl: **Post-reduction imaging is mandatory** to confirm anatomic alignment before casting. Loss of reduction within 1–2 weeks may necessitate percutaneous pinning or ORIF. ## Immobilization Details | Parameter | Standard Protocol | | --- | --- | | **Cast type** | Plaster or fiberglass, above-elbow (sugar-tong or full cast) | | **Duration** | 4–6 weeks (depends on age and fracture pattern) | | **Follow-up X-rays** | At 1–2 weeks to check for redisplacement | | **Physiotherapy** | Begin after cast removal; emphasize finger, elbow, shoulder ROM | [cite:Rockwood & Green's Fractures in Adults Ch 20]
