Treatment for a Displaced Great Toe Fracture
For displaced great toe fractures, surgical fixation is indicated when displacement exceeds 2mm, particularly for intra-articular fractures, to prevent interphalangeal joint arthritis and functional impairment 1.
Initial Assessment and Imaging
Start with weightbearing AP, lateral, and sesamoid axial radiographs of the foot 2. These views will determine:
- Degree of displacement (>2mm threshold for surgery)
- Intra-articular involvement
- Joint congruency
- Presence of malrotation or malangulation
Treatment Algorithm
Surgical Indications (Choose Surgery If ANY Present):
- Intra-articular fractures with >2mm displacement 1
- Metadiaphyseal fractures with malrotation or malangulation 1
- Open fractures 1
- Unstable fractures 1
- Joint incongruence 3
Surgical Approach Options:
For intra-articular fractures of the interphalangeal joint:
- Use a dorsomedial approach along the medial border of the extensor hallucis longus tendon 3
- This minimizes soft tissue injury while allowing rigid fixation
- Enables early weightbearing and range of motion 3
Fixation methods (in order of preference for rigid fixation):
- Screw fixation - provides strongest construct, allows early mobilization 4, 5
- Modified extension block technique with K-wires - effective for articular fragments without residual hardware 6
- K-wire fixation alone - for simpler fracture patterns 3
Conservative Management (Only If ALL Criteria Met):
- Displacement <2mm
- No joint incongruence
- Stable fracture pattern
- Non-articular or minimally articular involvement
Use extension splinting for 4-6 weeks 5.
Critical Pitfalls to Avoid
Nonoperative treatment of displaced fractures leads to:
- Degenerative arthritis of the interphalangeal joint 3
- Chronic pain and range of motion limitation 3
- Valgus deformity 1
- Gait disturbances and weightbearing difficulties 3
The key error is underestimating displacement - fractures appearing "minimally displaced" on initial radiographs often have >2mm displacement requiring surgery 1.
Postoperative Protocol
- Interphalangeal joint immobilization with K-wire for 4 weeks if used 4
- Weightbearing allowed at 4-5 weeks postoperatively 4
- Full recovery typically achieved by 3 months with appropriate surgical fixation 5
Use rigid implants (screws preferred) to maintain alignment during healing and minimize reduction loss 1. The evidence strongly supports surgical intervention for displaced fractures to prevent long-term complications that significantly impact quality of life.
