Metacarpal fracture


Hello doctor, I was in a car accident last Thursday, and the X-ray diagnosis showed fractures of the 3rd, 4th, and 5th metacarpal bones in my right hand.
I would like to know if it is possible to just use a cast without surgery.
I am mainly concerned about the potential complications from surgery, incomplete rehabilitation, whether my hand will be unable to fully extend, and if there will be any scarring after the operation.

Dr. Chen Bochen reply Orthopedics


Hello Jean, if a scaphoid fracture is non-displaced or has a displacement of less than 2mm, surgery may not be necessary.
However, if the angulation is greater than 10 degrees or the displacement exceeds 2mm, surgery is recommended to prevent future impairment of hand function.
There will be some scarring from the surgery, but you can ask the doctor to use cosmetic sutures or scar reduction mesh.

Metacarpal fractures, particularly those involving the third, fourth, and fifth metacarpals, can often be treated without surgery, depending on the specific characteristics of the fracture. In your case, since you mentioned that your X-ray diagnosis indicates fractures of the right hand's third, fourth, and fifth metacarpals, it's essential to consider several factors before deciding on a treatment plan.

1. Type and Severity of the Fracture: The treatment approach largely depends on whether the fractures are displaced or non-displaced. Non-displaced fractures, where the bone fragments remain aligned, can often be treated conservatively with immobilization in a cast or splint. Displaced fractures, where the bone fragments have shifted out of alignment, may require surgical intervention to realign the bones properly.

2. Conservative Treatment: If your fractures are non-displaced, immobilization with a cast or splint is a common and effective treatment. This method allows the bones to heal naturally while minimizing the risk of complications. The immobilization period typically lasts around 4 to 6 weeks, during which you should avoid using the affected hand for any activities that could stress the fracture site.

3. Concerns About Surgery: Your concerns regarding surgery are valid. Surgical intervention can lead to complications such as infection, scarring, and stiffness. However, if surgery is necessary to ensure proper alignment and healing, the benefits often outweigh the risks. It's crucial to discuss these concerns with your orthopedic surgeon, who can provide insights based on the specifics of your fracture.

4. Rehabilitation: Regardless of whether you choose conservative treatment or surgery, rehabilitation is essential for restoring function and strength to your hand. If you opt for non-surgical treatment, physical therapy may begin once the cast is removed. This therapy will focus on regaining range of motion, strength, and function. If surgery is performed, rehabilitation may start earlier, depending on the surgeon's recommendations.

5. Long-term Outcomes: Many patients who undergo conservative treatment for metacarpal fractures achieve excellent outcomes, with full recovery and no long-term complications. However, some may experience stiffness or difficulty fully extending their fingers, particularly if the fracture was more complex or if there was a delay in seeking treatment. Regular follow-ups with your doctor will help monitor your healing progress.

6. Scarring: If surgery is performed, there may be some scarring, but this can often be minimized with proper surgical techniques and post-operative care. Non-surgical treatment typically results in no visible scars, as the skin is not incised.

7. When to Seek Further Evaluation: If you notice increased pain, swelling, or any signs of complications (such as numbness or inability to move your fingers), it's essential to seek medical attention promptly.
In conclusion, it is possible to treat metacarpal fractures without surgery, especially if they are non-displaced. However, the decision should be made in consultation with your orthopedic surgeon, who can assess the specifics of your injury and recommend the best course of action. Rehabilitation will be crucial in ensuring that you regain full function of your hand, regardless of the treatment method chosen.
