When it comes to Poland syndrome, many people have never heard of it, but it is relatively common in hand surgery clinics. A few days ago, I received such a small patient who came all the way from Beijing to my clinic. This little baby had Poland Syndrome, with short fingers and syndactyly on the right hand, and usually had a hard time grasping things. Today, with this little baby to see the clinic as a wedge, to answer a few questions that parents are more concerned about: First, what is Poland syndrome? Poland syndrome is a group of congenital upper limb deformity sequence combination with one side of the chest muscle deficiency or dysplasia, upper limb, especially short hand, short fingers or syndactyly as the main clinical manifestations. Second, what are the characteristics of Poland syndrome? Poland syndrome is characterized by the following four main features: 1, unilateral shortness of the show, middle and ring little finger; 2, syndactyly of the affected fingers; 3, hypoplasia of the fingers; 4, hypoplasia or absence of the pectoralis major muscle and clavicle head on the same side. How to treat Poland syndrome? According to the previous definition of Poland syndrome, we suggest that the treatment of Poland syndrome should focus on solving the problems of syndactyly and short fingers of the affected hand. For syndactyly, the affected hand should undergo finger splitting surgery to release the fingers that were originally joined together, so that they can develop. 2, short fingers For babies with short fingers, whether they need to be lengthened or not generally depends on its growth rate and the degree of proportionality of the affected hand. If by a certain age, the baby’s affected hand finger growth rate is relatively normal and the proportion of the affected hand is more coordinated, there is no need to consider doing the extension. If the affected hand does not grow much, and the proportion of the whole hand is not harmonized, this situation can be considered to do lengthening. Can the syndactyly be separated at one time? In the past, the syndactyly of babies with Poland syndrome could only be separated several times. Nowadays, we can separate all the joined fingers at once by adopting the skin-less technique, which reduces the number of surgeries, makes babies suffer less, and allows parents to spend less time caring for their babies. Fifth, after surgery, can the affected hand return to normal? This question is also a concern of many parents of babies, in fact, after surgery, many children’s hand function is better, such as: grasp, grip, brush teeth, chopsticks to eat and so on. However, it is somewhat difficult to return to full normalcy. Sixth, how old is better for the baby’s surgery? Generally speaking, if the child is healthy and has reached the weight standard, it is usually possible to operate when the child is 6-8 months old. Because if the treatment is carried out in this period of time, the skin defect in the process of syndactyly will be smaller, the healing time will be shorter, the quality of healing will be better, and after the functional exercise is followed, the whole recovery effect will be more ideal. What is the duration of surgery? The length of surgery is generally 2.5 hours – 3 hours. What should I pay attention to when I take care of my baby after the surgery? 1.Kirschner’s Needle Since the baby needs to undergo finger splitting surgery, in order to fix the split finger, Kirschner’s Needle will be used for fixation. It is usually removed within 4-6 weeks time after surgery. 2.Bathing It is a little difficult to take the child in the early postoperative period, because the surgical site can not see water before it grows well, and parents must pay extra attention to the process of care in the usual way. Generally speaking, it takes about 6-8 weeks for the wound to grow back. During this time, the wound should not be exposed to water and the baby should be kept as cool as possible to minimize sweating.
