the Risks of Untreated Finger Tendon Injuries

The tendon of the little finger's extensor muscle is ruptured?

Due to a car accident, my right pinky finger struck a wall, resulting in a rupture of the extensor tendon of the pinky.
It took about six months to realize the injury and consult a physician.
The doctor mentioned that surgery is needed for repair and stabilization, but due to the time elapsed, there is concern about tendon atrophy.
If the tendon cannot be sutured, a tendon from the wrist may need to be harvested for the repair of the pinky.

I would like to know what complications might arise if I choose not to undergo surgery for the pinky.
Additionally, if a tendon from the wrist is used to repair the pinky tendon, what potential complications could occur in the wrist? If it is indeed necessary to harvest a tendon from the wrist for the pinky repair, would you recommend proceeding with the surgery, or is it better to leave it untreated? My job requires me to lift heavy objects, and I am concerned about the impact of removing a tendon from my wrist.
I would appreciate your advice, doctor.

Tendon rupture of the finger extensors may lead to issues such as finger pain, decreased strength, and joint flexion contractures, which can affect daily functional activities and quality of life.
Whether surgical treatment is necessary should be discussed on-site between the patient and a qualified physician, taking into account the actual condition, as well as evaluating the pros and cons and assessing the risks.
Although harvesting wrist tendons may cause damage to the wrist, affecting strength and joint stability, the impact can be minimized through proper surgical techniques and subsequent rehabilitation therapy, and there may not be a significant difference compared to the preoperative state.
It is recommended to seek further evaluation and treatment at a qualified orthopedic or rehabilitation clinic nearby.

When it comes to untreated finger tendon injuries, especially in the case of a ruptured extensor tendon in the little finger, there are significant risks and potential long-term consequences that should be carefully considered. In your situation, where the injury occurred due to a car accident and was not addressed for about six months, the implications can be quite serious.

Firstly, if the tendon is not surgically repaired, the little finger may not regain its full range of motion or strength. Tendons are crucial for the proper functioning of fingers, allowing for extension and flexion. Without the ability to extend the finger, you may experience difficulties with grip strength and dexterity, which can severely impact daily activities and job performance, especially if your work involves handling heavy objects. Over time, the lack of movement can lead to stiffness and further complications, such as joint contractures, where the finger becomes permanently bent.

Moreover, the longer the tendon remains unrepaired, the greater the risk of muscle atrophy and tendon retraction. This means that the muscle associated with the tendon may weaken and shrink, making it even more challenging to restore function later on. In some cases, the body may develop compensatory mechanisms, which can lead to overuse injuries in other parts of the hand or wrist due to altered movement patterns.

If surgical intervention is deemed necessary, the option of harvesting a tendon from the wrist to repair the little finger is a common practice. However, this procedure does come with its own set of risks and potential complications. The wrist tendon that is harvested may lead to decreased strength and function in the wrist, particularly in activities that require grip and lifting. Patients often report a feeling of weakness or instability in the wrist post-surgery, which can be concerning if your job involves heavy lifting.

In deciding whether to proceed with surgery, it is essential to weigh the benefits against the risks. If the surgery is successful, you may regain function in your little finger, which could improve your overall hand function and quality of life. On the other hand, if you choose to avoid surgery, you may face long-term limitations in the use of your little finger, which could affect your ability to perform tasks that require fine motor skills or grip strength.

It is crucial to have a thorough discussion with your orthopedic surgeon or hand specialist about your specific situation. They can provide insights based on the severity of the injury, the condition of the tendon, and your overall health and activity level. They may also suggest physical therapy post-surgery to help regain strength and mobility in both the little finger and the wrist.

In conclusion, untreated finger tendon injuries can lead to significant functional impairments and complications. If surgical repair is recommended, it is generally advisable to proceed, especially if you wish to maintain optimal hand function for your work and daily activities. However, ensure that you have a comprehensive understanding of the potential outcomes and rehabilitation process involved in the surgery.
