Scaphoid Fracture
What is a Scaphoid Fracture?
A scaphoid fracture is a break in one of the small bones in the wrist, known as the scaphoid bone, often resulting from a fall onto an outstretched hand.
- Common in young adults
- Risk of nonunion due to limited blood supply
Overview of the Condition
Prompt diagnosis and treatment are important to prevent complications such as avascular necrosis.
Symptoms
- Wrist pain, especially in the anatomical snuffbox
- Swelling and tenderness
- Difficulty bearing weight on the hand
Causes
Typically caused by a fall on an outstretched hand or direct trauma to the wrist.
Diagnosis
Diagnosis is confirmed with X-rays; CT or MRI may be used in cases of occult fractures.
Treatment Options
- Casting or splinting for non-displaced fractures
- Surgical fixation for displaced or unstable fractures
Conservative Management
Immobilization in a cast or splint is the primary treatment for non-displaced scaphoid fractures.
Rehabilitation Exercises
- Gradual range-of-motion exercises after cast removal
- Strengthening exercises for the wrist
- Physical therapy to restore function
Surgical Options
Surgery is considered for displaced fractures and may involve internal fixation using a screw.
Anatomy Overview
The scaphoid is one of the carpal bones located in the anatomical snuffbox of the wrist.
Affected Areas
- Wrist, specifically the anatomical snuffbox
- Adjacent carpal bones
Frequently Asked Questions
| Question | Answer |
|---|---|
| What is the risk of nonunion? | Due to limited blood supply, nonunion is a known risk. |
| How long is the immobilization period? | It typically lasts 6-12 weeks depending on fracture severity. |
Prevention Strategies
- Use proper techniques during falls
- Wear wrist guards during high-risk activities
