When a person has a hunchback, the spine protrudes?


Hello doctor, when I stand upright, the flesh above my spine sinks in, but when I bend over, my spine protrudes, and I can feel the individual vertebrae.
When I touch it, there is no obvious scoliosis.
Is this a problem with my spine or am I just too thin? (Weight: 55 kg / Height: 169 cm)

Guo Tongxue, 10~19 year old female. Ask Date: 2023/05/22

Dr. Shi Guozheng reply Orthopedics


It is possible that being too thin could be a factor.
To determine if there is an issue, it is best to get an X-ray of the spine for evaluation.

Understanding spinal protrusion and its implications for health can be quite complex, especially when considering factors such as body composition, posture, and underlying spinal conditions. Based on your description, it seems you are experiencing a phenomenon where your spine appears to have a different contour when standing straight versus bending forward. This could be attributed to several factors, including your body fat percentage, muscle tone, and spinal alignment.

Firstly, it is essential to understand that the spine is a dynamic structure composed of vertebrae, intervertebral discs, ligaments, and muscles. When you stand upright, the alignment of these components can create a smooth contour. However, when you bend forward, the natural curvature of the spine may become more pronounced, leading to a protrusion effect. This is not uncommon and can be influenced by your overall body composition. At a height of 169 cm and a weight of 55 kg, your Body Mass Index (BMI) is approximately 19.2, which is considered within the normal range but on the lower end. Being underweight can lead to reduced muscle mass and fat, which might make the bony structures of your spine more prominent.

In terms of health concerns, the absence of noticeable scoliosis (sideways curvature of the spine) when palpating your spine is a positive sign. However, if you are experiencing discomfort or pain, it may be worth investigating further. Conditions such as spinal protrusion or herniation can occur without significant symptoms, but they can lead to issues if they compress nearby nerves or affect spinal stability. Given that you do not report any significant pain or discomfort, it is likely that your spinal appearance is more related to your body composition rather than a serious health issue.

To ensure your spinal health, consider the following recommendations:
1. Strengthening Exercises: Incorporate exercises that strengthen your core muscles, including the abdominal and back muscles. A strong core supports the spine and can help maintain proper posture.

2. Posture Awareness: Pay attention to your posture throughout the day. Maintaining a neutral spine position while sitting, standing, and walking can prevent undue stress on the spinal structures.

3. Flexibility Training: Engage in regular stretching or yoga to improve flexibility and promote spinal health. This can help alleviate any tension in the muscles surrounding the spine.

4. Nutrition: Ensure you are consuming a balanced diet that supports muscle health. Adequate protein intake is crucial for muscle maintenance, especially if you are on the lower end of the weight spectrum.

5. Regular Check-ups: If you have concerns about your spinal health or if you begin to experience pain, consider consulting a healthcare professional. They may recommend imaging studies or physical therapy to assess your spine's condition more thoroughly.

In conclusion, while your spinal appearance may raise questions, it does not necessarily indicate a health concern, especially in the absence of pain or discomfort. However, maintaining a healthy lifestyle that includes strength training, flexibility exercises, and proper nutrition is vital for overall spinal health. If you have further concerns or experience any changes in your symptoms, it is always best to consult with a healthcare provider for personalized advice and assessment.
