What is the treatment for a proximal fibula fracture?

Treatment of Proximal Fibula Fractures

Most proximal fibula fractures can be managed conservatively with immobilization and appropriate rehabilitation, while surgical intervention is reserved for specific cases with instability or associated injuries. 1

Initial Assessment

• Evaluate for associated injuries, particularly ankle injuries, as proximal fibula fractures may be part of more complex injury patterns such as Maisonneuve fractures (proximal fibula fracture with ankle involvement) 1
• Assess stability of the ankle joint and integrity of the syndesmosis, as this will guide treatment decisions 1
• Obtain appropriate imaging including radiographs to evaluate fracture pattern and location 2

Treatment Options

Conservative Management

• For isolated, stable proximal fibula fractures without syndesmotic disruption or ankle instability, conservative treatment is recommended 1
• Treatment typically includes:
  • Immobilization with a cast or walking boot for 4-5 weeks 3
  • Pain management with appropriate analgesia 4
  • Protected weight-bearing as tolerated 4
• Conservative management has shown excellent outcomes in most cases, with studies reporting good to excellent results in the majority of patients 1

Surgical Management

• Surgical intervention is indicated for:
  • Unstable fractures with complete syndesmotic disruption 1
  • Fractures associated with ankle instability requiring fixation 1
  • Proximal fibula fractures associated with tibial plateau fractures that affect stability 2
• Surgical options include:
  • Open reduction and internal fixation for unstable fractures 1
  • Syndesmotic fixation when indicated 5
  • Positioning screws that may be removed after 6 weeks prior to full weight-bearing 5

Rehabilitation Protocol

• When immobilization is discontinued, progressive motion exercises should be initiated to achieve optimal outcomes 4
• Rehabilitation should include:
  • Early post-fracture physical training followed by long-term balance training and fall prevention 4
  • Individualized rehabilitation goals established before developing the rehabilitation plan 4
  • Careful progression of weight-bearing activities 4
• Avoid overly aggressive physical therapy as it may increase the risk of complications 4

Monitoring and Follow-up

• Regular radiographic assessment to ensure proper bone healing 6
• Monitor for potential complications such as:
  • Chronic instability of the proximal fibula 5
  • Peroneal nerve palsy (particularly important as the peroneal nerve courses around the proximal fibula) 5
  • Snapping or proximal fibular pain 5

Special Considerations

• Pediatric proximal fibula fractures are rare (only 0.09% of all pediatric fractures) but typically heal well with conservative management 3
• High-energy trauma mechanisms should raise suspicion for associated injuries, particularly in the ankle and knee 5
• Proximal tibiofibular joint dislocations associated with tibial shaft fractures require special attention and often surgical management 5

Remember that proper diagnosis and appropriate treatment of proximal fibula fractures are essential to prevent chronic instability and functional limitations.
