Minimally Invasive Calcaneal Fracture Surgery: Is Waiting for Swelling to Subside Really Necessary? Insights from 155 Cases

A seemingly “routine” calcaneal fracture surgery—Yet it raises a sharp and critical question:

Do we really need to wait 7–14 days for swelling to subside before operating?

Traditional Belief: Surgery Must Wait for the “Wrinkle Sign”

For decades, the standard teaching has been clear:

• Surgery for calcaneal fractures should be delayed

• Wait until soft tissue swelling subsides

• Operate only after the “wrinkle sign” appears (typically 7–14 days)

But is this delay truly beneficial for patients?

Counterintuitive Finding #1: Waiting May Not Improve Outcomes

A study published in the Journal of Clinical Medicine by Rodemund et al. challenges this long-held belief.

Early vs Delayed Surgery

• Surgery on admission day or next day vs Surgery after 7+ days

• AOFAS Score: 87.3 vs 93.4

• p = 0.440 (no statistically significant difference)

In other words, waiting an extra week did not lead to better functional outcomes.

Why Early Surgery Works

Minimally invasive techniques make early intervention feasible:

• Stab incisions (1–2 cm) → minimal soft tissue disruption

• Two-point distraction reduction → no extensive dissection

• Short operative time (average 76.2 minutes)

These factors significantly reduce soft tissue complications—eliminating the need to “wait.”

Counterintuitive Finding #2: Plates May Not Be Necessary

The study utilized a simplified yet effective technique:

Surgical Strategy

• Two-point distraction reduction

• Percutaneous stab incisions

• Screw-only fixation (primarily 7.3 mm fully threaded screws)

What This Means Clinically

❌ No plate required
❌ No large lateral incision
✅ Early functional rehabilitation (starting postoperative day 1)
✅ Easier implant removal (can be done under local anesthesia)

Is Screw-Only Fixation Biomechanically Reliable?

The study is supported by prior biomechanical and clinical evidence:

• Smerek (2008): Comparable strength between screw fixation and plate fixation

• DeWall (2010): No significant difference in loss of reduction

• Baoyou (2016): Meta-analysis shows similar outcomes between cannulated screws and plates

Conclusion: Screw-only fixation is biomechanically sound and clinically effective.

Clinical Outcomes: Data from 155 Patients

This retrospective study analyzed:

• 155 patients

• 168 calcaneal fractures (2015–2020)

Key Results

Minimally invasive screw fixation effectively restores calcaneal height and alignment.

Suitable Even for High-Risk Patients

One of the most clinically relevant findings:

This technique is safe and effective for:

• Elderly patients

• Patients with comorbidities

• Smokers

Groups traditionally considered high-risk for wound complications.

Does Surgical Timing Affect Outcomes?

Functional Outcomes by Timing

• p = 0.440 → No statistical significance

Conclusion: Surgical timing does NOT significantly impact functional outcomes when standardized minimally invasive techniques are used.

Trend Shift: Less Immobilization, Faster Recovery

Follow-up data (2015–2020) show:

• Decreasing use of postoperative plaster immobilization

• Increasing adoption of early functional rehabilitation without fixation

A clear shift toward enhanced recovery protocols (ERAS) in foot and ankle trauma.

Core Insight: Challenging Long-Standing Dogma

This study does not merely introduce a new technique—it challenges old assumptions:

• Do we really need to wait for swelling to subside?

• Is plate fixation always necessary?

• Or are these just practices we follow because “that’s how it’s always been done”?

Evidence suggests it’s time to rethink.

Conclusion

Minimally invasive calcaneal fracture surgery using percutaneous reduction and screw-only fixation offers:

• Comparable functional outcomes

• Lower complication rates

• Faster recovery

• Greater flexibility in surgical timing

Early surgery is not only feasible—it may be the smarter choice.
