Calcaneus fractures trauma orthobullets provide a concise, high-yield overview for managing complex heel injuries in acute settings. These summaries emphasize mechanism, imaging, and initial stabilization strategies that align with advanced trauma life support principles.
Orthopedic teams rely on structured references to streamline decision-making and reduce variability in care. The following sections organize key concepts into focused sections and a quick-reference table for rapid clinical retrieval.
| Feature | Details | Clinical Relevance | Initial Action |
|---|---|---|---|
| Mechanism | Axial loading from falls, motor vehicle collisions, or crush injuries | Predicts associated injuries and energy of impact | Assess for spinal, chest, and long-bone injury |
| Imaging | Weight-bearing CT, ankle views, Bohler angle assessment | Guides surgical planning and detects subtalar involvement | Obtain plain films first, then CT if indicated |
| Soft Tissue | High risk of wound complications, compartment syndrome | Impacts timing of definitive fixation | Monitor pressures, avoid premature reduction |
| Surgical Goals | Restore height, correct varus, joint congruity, stable construct | Improves posttraumatic arthritis risk and function | Plan reduction and approach based on fracture pattern |
Anatomy and Injury Patterns of the Calcaneus
The calcaneus is the largest tarsal bone and forms the foundation of the rearfoot. Its complex geometry and cancellous architecture make it susceptible to comminution under high-energy loads, often producing intra-articular involvement of the subtalar joint.
Trauma orthobullets highlight that intra-articular fractures frequently disrupt the posterior facet, leading to loss of height and varus malalignment. Recognizing the arc of Böhler is essential when evaluating subtle displacements on lateral radiographs.
Initial Assessment and Imaging Protocol
Clinical Evaluation
Primary and secondary surveys must rule out life-threatening injuries before focused orthopaedic assessment. Pay particular attention to neurovascular status of the posterior tibial nerve and peroneal tendons, which can be compromised by fracture displacement or compartmental changes.
Imaging Strategy
Standard trauma imaging includes ankle anteroposterior, mortise, and lateral views, with the calcaneus best seen on the lateral projection. Advanced trauma life support–style orthobullets recommend weight-bearing CT early to evaluate joint step-off and guide definitive management.
Surgical and Nonsurgical Management Options
Operable high-displacement fractures, especially those with significant articular incongruity or loss of Bohler height, typically benefit from open reduction and internal fixation. Minimally invasive techniques and limited-incision approaches aim to reduce wound complications while achieving stable fixation.
In selected low-displacement or nonoperative candidates, immobilization in a neutral position with non-weight-bearing for several weeks may be considered. However, malunion risk and chronic pain often favor anatomical restoration when soft tissue conditions permit early intervention.
Complications and Prognostic Factors
Posttraumatic arthritis remains the most common long-term complication, influenced by initial joint depression, residual varus, and secondary subtalar arthritis. Wound problems, deep infection, and complex regional pain syndrome are more likely in high-energy injuries with significant soft tissue damage.
Functional prognosis depends on fracture displacement, articular involvement, timing of reduction, and patient comorbidities. Early multidisciplinary care, including orthopaedic, plastic, and rehabilitation services, improves outcomes and reduces length of stay.
Key Takeaways for Clinical Practice
- Recognize axial loading patterns and screen for associated trauma.
- Use weight-bearing CT to evaluate subtalar joint involvement.
- Individualize surgery versus nonoperative care based on displacement and soft tissue status.
- Anticipate and mitigate wound complications with careful surgical planning.
- Monitor alignment and joint space during follow-up to detect posttraumatic arthritis early.
FAQ
Reader questions
What defines a high-energy calcaneus fracture requiring surgical fixation?
Significant displacement, loss of Bohler angle, intra-articular involvement, concurrent subtalar dislocation, or open fractures typically warrant operative management to restore joint congruity and prevent malunion.
How do you reduce wound complications after calcaneus fracture surgery? Use meticulous soft-tissue handling, limited approaches when appropriate, staged procedures if edema is severe, and close monitoring of tissue perfusion to minimize infection and necrosis risks. When is weight-bearing allowed after calcaneus fixation?
Gradual progression is common once radiographic evidence of healing and sufficient construct stability are confirmed, often starting with partial weight-bearing and advancing to full load over several weeks.
What imaging protocol is recommended for follow-up?
Serial radiographs at standard intervals, supplemented by CT when assessing articular reduction or suspected hardware failure, help guide decisions on weight-bearing progression and additional interventions.
