Fifth Metatarsal Fractures: Recovery and Rehabilitation Insights - Orthopedics

More Info

---

Fifth metatarsal fractures are common injuries, particularly among athletes and active individuals. They can occur due to various reasons, including twisting injuries, direct trauma, or overuse. In your case, you experienced a complete transverse fracture with some displacement, which is significant but not uncommon. The treatment approach of using a cast for six weeks is standard for this type of fracture, especially when surgery is not deemed necessary.

After the cast was removed, it is not unusual to experience stiffness, swelling, and difficulty in bearing weight on the affected foot. The stiffness in your ankle, foot muscles, and heel can be attributed to a combination of immobilization during the healing process and the body's natural response to injury. When a limb is immobilized, the surrounding muscles can weaken and shorten, leading to stiffness and decreased range of motion. This is often referred to as "disuse atrophy."
Regarding your concern about the timeline for recovery, it is essential to understand that healing times can vary significantly based on several factors, including the severity of the fracture, your overall health, age, and any previous injuries. In general, most fifth metatarsal fractures heal within 6 to 8 weeks, but complete recovery, including regaining full strength and range of motion, can take several months. Given that you are now 10 weeks post-injury and still experiencing difficulties, it is crucial to engage in a structured rehabilitation program.

Rehabilitation typically involves several phases:
1. Initial Phase (0-6 weeks post-cast removal): Focus on reducing swelling and regaining range of motion. Gentle range-of-motion exercises for the ankle and foot can be beneficial. Ice and elevation can help manage swelling.

2. Strengthening Phase (6-12 weeks post-cast removal): As swelling decreases, you can begin to incorporate strengthening exercises for the foot and ankle. This may include resistance bands, toe raises, and balance exercises. Gradually increasing weight-bearing activities is essential, but it should be done cautiously to avoid re-injury.

3. Functional Phase (3-6 months post-injury): This phase focuses on returning to normal activities and sports. You may engage in more dynamic exercises, including walking, jogging, and sport-specific drills, depending on your comfort and the advice of your healthcare provider.

Given your history of an open fracture in the same ankle 20 years ago, there may be some residual effects, such as altered biomechanics or chronic stiffness, that could influence your current recovery. It is essential to communicate this history to your healthcare provider, as they may recommend specific rehabilitation strategies to address any underlying issues.

In terms of when you can expect to walk normally again, many individuals can return to regular walking within 12 weeks post-injury, but this can vary. Full recovery, including the ability to engage in sports or high-impact activities, may take anywhere from 3 to 6 months or longer, depending on your progress and any complications.

If you continue to experience significant stiffness, swelling, or pain, it may be beneficial to consult with a physical therapist or your orthopedic specialist. They can provide tailored exercises and modalities to help improve your recovery. Additionally, if you have not already done so, consider discussing the possibility of imaging studies (like an X-ray or MRI) to rule out any complications, such as non-union or malunion of the fracture.

In summary, while your current symptoms may be concerning, they are not uncommon following a fifth metatarsal fracture. A structured rehabilitation program, patience, and regular follow-up with your healthcare provider will be key to your recovery.
