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

1. Gradual range-of-motion exercises after cast removal
2. Strengthening exercises for the wrist
3. 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

QuestionAnswerWhat 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

Additional Treatments

Post-cast rehabilitation is crucial for restoring wrist function.
