A 28-year-old male laborer presents with pain and swelling over the dorsal wrist following a fall on an outstretched hand (FOOSH). Anatomical snuffbox tenderness is present. Plain radiographs are normal. Regarding the management and complications of scaphoid fractures, all of the following are correct EXCEPT:

Explanation

## Scaphoid Fracture Management: Operative vs. Conservative Approach ### Clinical Scenario Context This patient has classic signs of scaphoid fracture (FOOSH mechanism, snuffbox tenderness) but negative plain radiographs—a common diagnostic dilemma in orthopedic practice. ### Key Point: Operative Fixation is NOT Routine for All Fractures **Key Point:** Early operative fixation with percutaneous screw placement is NOT indicated for all acute scaphoid fractures. It is reserved for: - Displaced fractures (>2 mm) - Fractures in high-demand athletes or laborers (to allow early mobilization) - Nonunions or established AVN - Specific proximal pole fractures Undisplaced fractures in compliant patients are managed conservatively with immobilization. ### High-Yield: Diagnostic Algorithm **High-Yield:** When clinical suspicion is high but plain films are negative: 1. Perform MRI (gold standard for early diagnosis) or CT 2. If confirmed, immobilize immediately 3. Repeat plain films in 10–14 days (fracture line may become visible) ### Management Principles by Fracture Type | Fracture Type | Treatment | |---|---| | Undisplaced, distal/middle third | Thumb spica cast 8–12 weeks | | Undisplaced, proximal third | Thumb spica cast 12–16 weeks (longer healing) | | Displaced (>2 mm) | Percutaneous screw fixation | | Nonunion | Operative fixation + bone graft | | AVN | Scaphoid reconstruction or arthrodesis | ### Clinical Pearl: Why Conservative Treatment Works **Clinical Pearl:** Undisplaced scaphoid fractures heal reliably with immobilization alone in >95% of cases when compliance is good. Operative fixation in these cases adds cost and morbidity without improving outcomes—it is NOT a universal solution. ### Correct Answer Rationale Option 4 is **FALSE** because: - Not all acute scaphoid fractures require operative fixation - Undisplaced fractures heal well with conservative management - Operative fixation is reserved for displaced, nonunion, or high-demand cases - The statement's claim of "reliable prevention" of nonunion in ALL fractures is an overstatement not supported by evidence ### Mnemonic: Scaphoid Management Decision **Mnemonic:** **CAST** = **C**onservative for undisplaced, **A**dvanced imaging if plain films negative, **S**crew fixation for displaced, **T**humb spica immobilization.
