Herbert Screw Fixation of Scaphoid Fractures
Summary
Herbert screw fixation for scaphoid fractures effectively achieves union in most cases. While generally successful, outcomes depend on fracture stability and avoiding complications like screw protrusion for optimal results.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- Scaphoid fractures are common wrist injuries.
- Unstable scaphoid fractures require surgical intervention for optimal healing.
- The Herbert screw is a common fixation device for scaphoid fractures.
Purpose of the Study:
- To evaluate the outcomes of open reduction and internal fixation using the Herbert screw for scaphoid fractures.
- To assess union rates and functional results based on fracture type and complications.
Main Methods:
- Retrospective review of 44 scaphoid fractures treated with Herbert screw fixation.
- Fracture classification using the Herbert system (Types B, C, D).
- Assessment of radiological union and functional outcomes using the Mayo wrist score.
Main Results:
- Sound radiological union was achieved in 42 out of 44 cases (95.5%) at an average of 3.2 months.
- Excellent or good results (Mayo wrist score) were reported in 36 out of 44 patients (81.8%).
- Complications included nonunion in 2 cases, requiring revision grafting, and screw protrusion in 1 case.
Conclusions:
- Herbert screw fixation is an effective treatment for scaphoid fractures, achieving high union rates.
- Functional outcomes are generally good, but complications such as nonunion and screw protrusion can impact results.
- Careful patient selection and surgical technique are crucial for successful outcomes in scaphoid fracture fixation.
