Jones Fracture
What is a Jones Fracture?
A Jones Fracture is a break in the proximal diaphysis of the fifth metatarsal, typically occurring near the base of the bone.
- Commonly occurs from an inversion injury of the foot
- Seen frequently in athletes and active individuals
Overview of the Condition
This fracture is notable for its risk of nonunion due to a poor blood supply to the area.
Symptoms
- Pain and swelling over the outer side of the foot
- Difficulty bearing weight or walking
- Bruising around the fifth metatarsal
Causes
A Jones Fracture often results from an acute inversion injury, especially during sports activities.
Diagnosis
Diagnosis is confirmed via X-rays. CT scans may be used in cases where nonunion is suspected.
Treatment Options
- Casting or immobilization for non-displaced fractures
- Surgical fixation with intramedullary screws for displaced fractures or in athletes
Conservative Management
Non-surgical care includes immobilization with a cast or walking boot, along with non-weight-bearing protocols.
Rehabilitation Exercises
- Gradual weight-bearing as healing progresses
- Range of motion and strengthening exercises after cast removal
- Physical therapy to restore normal gait
Surgical Options
Surgery may involve intramedullary screw fixation to promote union, especially in high-demand athletes.
Anatomy Overview
The fifth metatarsal bone, located on the lateral aspect of the foot, is the primary structure involved in a Jones Fracture.
Affected Areas
- Fifth metatarsal
- Lateral aspect of the foot
Frequently Asked Questions
| Question | Answer |
|---|---|
| How long is the recovery period? | Recovery typically takes 6-8 weeks for non-surgical treatment, but may be longer for surgical cases. |
| Can nonunion occur? | Yes, due to the limited blood supply in this area, nonunion is a risk. |
Prevention Strategies
- Use proper footwear during sports
- Incorporate strength and flexibility training
- Practice safe techniques during high-risk activities
