Spinal surgery


Dear Dr.
Yang,
My father is seventy years old.
A month ago, he was diagnosed with a liver abscess and received treatment at Kaohsiung Veterans General Hospital.
The bacteria have since infected his spinal cord and eroded a vertebra.
He underwent surgery a week ago to replace the affected vertebra with an artificial bone.
Two days ago, he was able to get out of bed and walk with assistance, but today he is unable to get out of bed due to a gout attack.
I would like to ask the doctor: Is the artificial bone strong? Will it need to be replaced in the future? What dietary and lifestyle considerations should we be aware of given his condition? Thank you for your response!

Dear Kitty,
Liver abscess combined with spinal osteomyelitis is a challenging condition to treat.
If it leads to spinal instability, surgical intervention, as you mentioned, is necessary.
The typical approach involves two surgeries: first, a posterior approach to place spinal screws, followed by an anterior approach to thoroughly debride the infected area and secure bone grafting (usually using the patient's own bone).
The fixation is then reinforced with plates and screws from the anterior approach.

The artificial bone you referred to may be a misnomer for bone cement or autologous bone grafts.
Currently, artificial bone substitutes do not possess sufficient strength to replace the spine, and no physician would use such methods for treatment.
The purpose of placing bone in the thoroughly debrided area is to replace the diseased spine, so there is generally no need for further replacement.
Regarding daily life precautions, in addition to wearing a brace for at least six months, it is important to monitor the status of the liver abscess and consistently follow the physician's medication regimen to effectively manage this condition.

Wishing you a victorious battle!
Best,
Yang Zhengfan

Understanding spinal surgery, particularly when it involves the use of artificial bones, is crucial for patients and their families. Your father's situation, involving an infection that led to the replacement of a vertebra with an artificial bone, is complex and requires careful management to ensure recovery.

Firstly, regarding the strength and durability of artificial bones, modern orthopedic implants, including artificial vertebrae, are designed to be robust and can withstand significant loads. These implants are typically made from materials such as titanium or medical-grade polymers, which are biocompatible and resistant to corrosion. However, the longevity of an artificial bone can depend on several factors, including the patient's overall health, activity level, and adherence to post-operative care. In many cases, artificial bones can last for many years, but there are instances where they may need to be replaced due to wear, loosening, or complications such as infection.

Your father's recent surgery and the fact that he was able to walk with assistance just two days post-operation is a positive sign. However, the occurrence of a gout attack, which is characterized by sudden and severe pain, redness, and swelling in the joints, can complicate his recovery. Gout is often triggered by dietary factors, dehydration, and certain medications, and it can significantly impact mobility. It is essential to manage gout effectively to ensure that it does not hinder his rehabilitation process.

In terms of dietary and lifestyle considerations, here are some recommendations:
1. Hydration: Encourage your father to drink plenty of fluids, as staying hydrated can help prevent gout attacks. Water is the best choice.

2. Diet: A diet low in purines can help manage gout. Foods high in purines include red meat, organ meats, and certain seafood. Instead, focus on a diet rich in fruits, vegetables, whole grains, and low-fat dairy products. Cherries, in particular, have been shown to reduce the risk of gout attacks.

3. Weight Management: Maintaining a healthy weight can reduce the stress on his joints and lower the risk of gout attacks. If he is overweight, gradual weight loss may be beneficial.

4. Medication Management: Ensure that any medications prescribed for gout are taken as directed. Nonsteroidal anti-inflammatory drugs (NSAIDs) can help manage pain during an attack, but it’s important to consult with his healthcare provider regarding the best options.

5. Physical Activity: While it’s essential to engage in physical therapy and rehabilitation exercises as recommended by his healthcare team, he should avoid high-impact activities that could stress the surgical site or exacerbate his gout symptoms. Gentle range-of-motion exercises and walking with assistance can be beneficial.

6. Follow-Up Care: Regular follow-up appointments with his orthopedic surgeon and primary care physician are crucial. These visits will allow for monitoring of the artificial bone's integration and function, as well as management of any ongoing issues related to gout or other health concerns.

In conclusion, while artificial bones are generally strong and durable, the recovery process can be influenced by various factors, including the presence of conditions like gout. By focusing on a healthy lifestyle, adhering to dietary recommendations, and maintaining open communication with healthcare providers, your father can optimize his recovery and improve his quality of life. Always consult with his medical team for personalized advice and adjustments to his care plan.
