Can Growth Plates Close and Still Allow for Height Increase? - Pediatrics

The question of whether growth plates can close and still allow for height increase is a nuanced one. Growth plates, or epiphyseal plates, are areas of developing cartilage tissue located at the ends of long bones. They are responsible for the lengthening of bones during childhood and adolescence. Typically, these plates close after puberty, which signifies the end of height growth. For boys, this usually occurs around the ages of 16 to 18, while for girls, it tends to happen a bit earlier, around ages 14 to 16.

When a growth plate closes, it is generally accepted that the potential for further height increase is significantly diminished. This is because the closure of the growth plates indicates that the cartilage has been replaced by bone, thus halting any further elongation of the bone. Therefore, if your left hand's growth plate has closed, it is a strong indicator that you will not grow taller from that particular bone.

However, there are some nuances to consider. Some individuals may experience slight increases in height due to factors such as improved posture or spinal decompression, particularly after sleep. When you wake up in the morning, you may feel taller because the intervertebral discs in your spine have had time to rehydrate and expand overnight, leading to a temporary increase in height. This increase is not permanent, and it does not indicate actual bone growth.

Regarding your question about whether there is still a chance to grow taller even if the growth plates have closed, the consensus in the medical community is that the likelihood is very low. While some anecdotal evidence exists of individuals experiencing slight height increases after the typical age of growth plate closure, these instances are rare and often attributed to factors other than bone growth, such as posture improvement or weight loss.

In terms of physical activities like hanging from a bar (pull-ups), while these exercises can improve posture and strengthen the muscles supporting the spine, they do not stimulate bone growth in closed growth plates. Nutrition, including adequate protein intake, is essential for overall health and can support the body’s natural growth processes during the growth years, but it will not reverse the closure of growth plates.

In conclusion, if your growth plates have indeed closed, it is highly unlikely that you will experience any significant increase in height. However, maintaining good posture, engaging in regular physical activity, and ensuring a balanced diet can contribute to your overall well-being and may help you maximize your height potential during your growth years. If you have concerns about your height or growth, consulting with a healthcare professional or an endocrinologist can provide personalized insights and guidance.
