Index finger pollicization is the classic surgical procedure for Type V thumb hypoplasia, and it is also an option for some cases of floating thumb. Many people may already have some understanding of this procedure from previous educational materials. Today, we will talk about several questions that parents are most concerned about, hoping to help families who may need this information.
Congenital Absence of the Thumb
Changes before and after surgery
How is the index finger shortened during pollicization?
Some people are curious about how the index finger can be transformed into a thumb. In fact, this involves specific surgical techniques used in pollicization. Simply put, part of the bone segment of the index finger is removed to shorten it. However, the key point is creating a suitable angle between the reconstructed metacarpal and the middle finger's metacarpal, which allows the new thumb to perform opposition. With this proper angle, the child will be able to carry out the thumb-to-finger opposition movement after surgery.
Changes before and after surgery
Why are there still only four fingers after the surgery? Was the surgery pointless?
Some parents may wonder: if there are still four fingers after pollicization, why does the child's hand function improve?
This is because the thumb plays an extremely important role in human hand function. Without a thumb, many everyday tasks become difficult or impossible-for example, twisting a towel or holding a pen to write. Without a thumb, the overall function of the hand is significantly reduced.
After pollicization, the child essentially gains a functional thumb. This makes the hand function much more complete and allows the child to perform tasks that would otherwise be impossible without a thumb. Therefore, the surgery is far from pointless-in fact, it is very meaningful for the child's functional development.
Changes before and after surgery
I believe that now everyone has gained a new understanding of index finger pollicization. In general, pollicization can compensate for some of the lost thumb function and appearance in children with thumb absence. In the long run, it is an option that can help change the child's current situation and give them a better future.
