Can Surgical Revision Improve Sensation After Finger Injury?

Post-traumatic suturing

Hello doctor, when I was about 16 years old, I accidentally injured the tip of my index finger while working in a factory, where it got caught in a machine.
I later had it stitched up.
Now, the area that was injured and the stitching site feel different from the rest of my finger.
I would like to know if it is possible to re-cut and re-stitch the area to improve the sensation and the appearance of the stitching site.
Thank you.

Due to the long time elapsed since the injury (16 years old) until now (40 years old), if the nerve in the finger was damaged at the time of the injury, it may no longer be recoverable.
A visit to the plastic surgery outpatient clinic for examination and confirmation is recommended.

More Info

Surgical revision can potentially improve sensation after a finger injury, but the success of such a procedure largely depends on several factors, including the nature of the original injury, the time elapsed since the injury, and the specific techniques used during the revision surgery.
In your case, since the injury occurred approximately 24 years ago, it is crucial to understand that the longer the time since the injury, the less likely it is that full recovery of sensation can be achieved. When a nerve is damaged, it can sometimes regenerate, but this process is slow and may not restore full function, especially if significant time has passed. If the nerve was severed or significantly injured at the time of the accident, the chances of complete recovery diminish over time.
Surgical revision typically involves re-evaluating the area of concern, which may include removing scar tissue, repairing or reconstructing nerves, and possibly re-aligning tendons or other structures that may have been affected. If there are any residual foreign materials, such as glass shards from a previous injury, these should be removed to prevent ongoing irritation and to promote healing.
Before considering surgical revision, it is advisable to consult with a hand surgeon or a plastic surgeon who specializes in hand injuries. They will conduct a thorough examination, which may include imaging studies, to assess the current state of the nerves, tendons, and surrounding tissues. They can provide a more accurate prognosis based on your specific situation.

In addition to surgical options, rehabilitation plays a vital role in recovery. Physical therapy can help improve mobility and function, even if sensation does not fully return. Techniques such as desensitization therapy, where the affected area is gradually exposed to different textures and sensations, can also help improve the perception of touch over time.

If you are experiencing significant discomfort or abnormal sensations, it is essential to seek medical advice. The surgeon may recommend a nerve conduction study to evaluate the function of the nerves in your finger. This information can guide treatment decisions and help set realistic expectations for recovery.

In summary, while surgical revision may offer some improvement in sensation and function after a finger injury, the likelihood of success decreases with the time elapsed since the injury. Consulting with a qualified specialist will provide you with the best options tailored to your specific circumstances.
