Most children with symbrachydactyly have excellent function in daily activities. Due to the length of their arm, they do not qualify for most artificial limbs. However, some adaptive prosthetics and equipment for sports and leisure activities may be helpful when the child is older. Children who demonstrate some functional movement in their remaining fingers and within the palm are evaluated for possible surgery such as toe transfers.

If a contracture is less than 30 degrees, it may not interfere with normal functioning. The common treatment is splinting and occupational therapy. Surgery is the last option for most cases as the result may not be satisfactory.

There is no standard treatment for the hand malformations in Apert due to the differences and severity in clinical manifestations in different patients. Every patient should therefore be individually approached and treated, aiming at an adequate balance between hand functionality and aesthetics.

However, some guidelines can be given depending on the severity of the deformities.

In general it is initially recommended to release the first and fourth interdigital spaces, thus releasing the border rays.

This makes it possible for the child to grasp things by hand, a very important function for the child's development. Later the second and third interdigital spaces have to be released.

Because there are three handtypes in Apert, all with their own deformities, they all need a different approach regarding their treatment:

- Type I hand usually needs only the interdigital web space release. First web release is rarely needed but often its deepening is necessary. Thumb clynodactyly correction will be needed.

- In type II hands it is recommended to release the first and fifth rays in the beginning, then the second and the third interdigital web spaces have to be freed. The clynodactyly of the thumb has to be corrected as well. The lengthening of the thumb phalanx may be needed, thus increasing the first web space. In both type I and type II, the recurrent syndactyly of the second web space will occur because of a pseudoepiphysis at the base of the index metacarpal. This should be corrected by later revisions.

- Type III hands are the most challenging to treat because of their complexity. First of all, it is advised to release the first and fourth webspace, thus converting it to type I hand. The treatment of macerations and nail-bed infections should also be done in the beginning. For increasing of the first web space, lengthening of the thumb can be done. It is suggested that in severe cases an amputation of the index finger should be considered. However, before making this decision, it is important to weigh the potential improvement to be achieved against the possible psychological problems of the child later due to the aesthetics of the hand. Later, the second and/or third interdigital web space should be released.

With growing of a child and respectively the hands, secondary revisions are needed to treat the contractures and to improve the aesthetics.

Because neither of the two thumb components is normal, a decision should be taken on combining which elements to create the best possible composite digit. Instead of amputating the most hypoplastic thumb, preservation of skin, nail, collateral ligaments and tendons is needed to augment the residual thumb. Surgery is recommended in the first year of life, generally between 9 and 15 months of age.

Surgical options depend on type of polydactyly.

Because newborns can breathe only through their nose, the main goal of postnatal treatment is to establish a proper airway. Primary surgical treatment of FND can already be performed at the age of 6 months, but most surgeons wait for the children to reach the age of 6 to 8 years. This decision is made because then the neurocranium and orbits have developed to 90% of their eventual form. Furthermore, the dental placement in the jaw has been finalized around this age.

The most common problem with syndactyly correction is creeping of the skin towards the fingertip over time. This is likely due to tension at the site of the repair between the digits. Additional surgery may be required to correct this. One critique of using skin grafts is that the grafts darken in the years after surgery and become more noticeable. Also, if the skin grafts are harvested from the groin area, the skin may grow hair. Finally, the fingers may deviate after surgery. This is most commonly seen in complex syndactyly (when there has been a bony joining of the fingers).

Because the circumference of the conjoined fingers is smaller than the circumference of the two separated fingers, there is not enough skin to cover both digits once they are separated at the time of surgery. Therefore, the surgeon must bring new skin into the area at the time of surgery. This is most commonly done with a skin graft (from groin or anterior elbow). Skin can also be used from the back of the hand by mobilizing it (called a "graftless" syndactyly correction), which requires planning over a period of months prior to surgery.

This type of procedure is recommended for Wassel types 1 and 2 (in which both thumbs are severely hypoplastic) by some congenital hand surgeons. The technique contains a composite wedge resection of the central bone and soft-tissue. This will be achieved with approach of the lateral tissue of each thumb. The goal is to achieve a normal thumb, what concerns the size, which is possible. If the width of the nail bed is greater than 70% of the contralateral thumb, it may be split. Then the nail bed will be repaired precisely.

Overall prognosis for children with amyoplasia is good. Intensive therapies throughout developing years include physical therapy, occupational therapy and multiple orthopedic procedures. Most children require therapy for years, but almost 2/3 are eventually able to walk, with or without braces, and attend school.

Surgery may be necessary to address the congenital deformities frequently occurring in conjunction with arthrogryposis. Surgery on feet, knees, hips, elbows and wrists may also be useful if more range of motion is needed after therapy has achieved maximum results. In some cases, tendon transfers can improve function. Congenital deformities of the feet, hips and spine may require surgical correction at or about one year of age.

Treatment for Klippel–Feil syndrome is symptomatic and may include surgery to relieve cervical or craniocervical instability and constriction of the spinal cord, and to correct scoliosis.

Failing non-surgical therapies, spinal surgery may provide relief. Adjacent segment disease and scoliosis are two examples of common symptoms associated with Klippel–Feil syndrome, and they may be treated surgically. The three categories treated for types of spinal cord deficiencies are massive fusion of the cervical spine (Type I), the fusion of 1 or 2 vertebrae (Type II), and the presence of thoracic and lumbar spine anomalies in association with type I or type II Klippel–Feil syndrome (Type III).

Adjacent segment disease can be addressed by performing cervical disc arthroplasty using a device such as the Bryan cervical disc prosthesis.

The option of the surgery is to maintain range of motion and attenuate the rate of adjacent segment disease advancement without fusion.

Another type of arthroplasty that is becoming an alternate choice to spinal fusion is Total Disc Replacement. Total disc replacement objective is to reduce pain or eradicate it.

Spinal fusion is commonly used to correct spinal deformities such as scoliosis. Arthrodesis is the last resort in pain relieving procedures, usually when arthroplasties fail.

Structural nasal deformities are corrected during or shortly after the facial bipartition surgery. In this procedure, bone grafts are used to reconstruct the nasal bridge. However, a second procedure is often needed after the development of the nose has been finalized (at the age of 14 years or even later).

Secondary rhinoplasty is based mainly on a nasal augmentation, since it has been proven better to add tissue to the nose than to remove tissue. This is caused by the minimal capacity of contraction of the nasal skin after surgery.

In rhinoplasty, the use of autografts (tissue from the same person as the surgery is performed on) is preferred. However, this is often made impossible by the relative damage done by previous surgery. In those cases, bone tissue from the skull or the ribs is used. However, this may give rise to serious complications such as fractures, resorption of the bone, or a flattened nasofacial angle.

To prevent these complications, an implant made out of alloplastic material could be considered. Implants take less surgery time, are limitlessly available and may have more favorable characteristics than autografts. However, possible risks are rejection, infection, migration of the implant, or unpredictable changes in the physical appearance in the long term.

At the age of skeletal maturity, orthognathic surgery may be needed because of the often hypoplastic maxilla. Skeletal maturity is usually reached around the age of 13 to 16. Orthognathic surgery engages in diagnosing and treating disorders of the face and teeth- and jaw position.

The complete or partial absence of the pectoralis muscle is the malformation that defines Poland Syndrome. It can be treated by inserting a custom implant designed by CAD (computer aided design). A 3D reconstruction of the patient's chest is performed from a medical scanner to design a virtual implant perfectly adapted to the anatomy of each one. The implant is made of medical silicone unbreakable rubber. This treatment is purely cosmetic and does not make up for the patient's imbalanced upper body strength.

The Poland syndrome malformations being morphological, correction by custom implant is a first-line treatment. This technique allows a wide variety of patients to be treated with good outcomes. Poland Syndrome can be associated with bones, subcutaneous and mammary atrophy: if the first, as for pectus excavatum, is successfully corrected by a custom implant, the others can require surgical intervention such as lipofilling or silicone breast implant, in a second operation.

The surgery takes place under general anaesthesia and lasts less than 1 hour. The surgeon prepares the locus to the size of the implant after performing a 8-cm axillary incision and inserts the implant beneath the skin. The closure is made in 2 planes.

The implant will replace the pectoralis major muscle, thus enabling the thorax to be symmetrical and, in women, the breast as well. If necessary, especially in the case of women, a second operation will complement the result by the implantation of a breast implant and / or lipofilling.

Lipomodelling is progressively used in the correction of breast and chest wall deformities. In Poland syndrome, this technique appears to be a major advance that will probably revolutionize the treatment of severe cases. This is mainly due to its ability to achieve previously unachievable quality of reconstruction with minimal scaring.

There is no known cure. In selected patients orthopaedic surgery may be helpful to try to gain some functionality of severely impaired joints.

Studies suggest that prenatal care for mothers during their pregnancies can prevent congenital amputation. Knowing environmental and genetic risks is also important. Heavy exposure to chemicals, smoking, alcohol, poor diet, or engaging in any other teratogenic activities while pregnant can increase the risk of having a child born with a congenital amputation. Folic acid is a multivitamin that has been found to reduce birth defects.

In rare cases, if diagnosed in utero, fetal surgery may be considered to save a limb which is in danger of amputation or other deformity. This typically would not be attempted if neither vital organs nor the umbilical cord were affected. This operation has been successfully performed on fetuses as young as 22 weeks. The surgery took place at Melbourne's Monash Medical Centre in Australia and is believed to be the earliest surgery of its type, as surgeons usually hold off on operating until the woman is in week 28 of gestation. There are also several facilities in the United States that have performed successful amniotic band release surgery.

Treatment usually occurs after birth and where plastic and reconstructive surgery is considered to treat the resulting deformity. Plastic surgery ranges from simple to complex depending on the extent of the deformity. Physical and occupational therapy may be needed long term.

Prosthetics may help some ABS sufferers to live more functional lives. The price and complexity of these prosthetics vary dramatically, but advances in 3-D printing have helped to increase the availability of artificial fingers while reducing their cost of production.

At the beginning of the surgery a tourniquet will be applied to the limb. A tourniquet compresses and control the arterial and venous circulation for about 2 hours. The constriction band must be dissected very carefully to avoid damaging the underlying neurovasculature. When the constriction band is excised, there will be a direct closure. This allows the fatty tissue to naturally reposition itself under the skin.

“With complete circumferential constriction bands, it is recommended that a two-stage correction approach be used. At the first operation, one-half of the circumference is excised and the other one-half can be excised after three to six months. This will avoid any problems to the distal circulation in the limb, which may already be compromised. Lymphedema, when present, will significantly improve within a few weeks of the first surgery.”

For the direct closure of the defect after dissecting a constriction band there are two different techniques:

1. Triangular flaps; For this technique the circumference between the two borders must be measured. Depending on the difference the number of triangular flaps can be decided. With a triangular flap you can create more skin.

2. Z/W-plasty; “Z-plasty is a plastic surgery technique that is used to improve the functional and cosmetic appearance of scars. It can elongate a contracted scar or rotate the scar tension line. The middle line of the Z-shaped incision (the central element) is made along the line of greatest tension or contraction, and triangular flaps are raised on opposite sides of the two ends and then transposed.”

In rare cases, if diagnosed in utero, fetal surgery may be considered to save a limb that is in danger of amputation or other deformity. This operation has been successfully performed on fetuses as young as 22 weeks. The Melbourne's Monash Medical Centre in Australia, as well as multiple facilities in the United States of America, have performed successful amniotic band release surgery.

Surgical correction is recommended when a constriction ring results in a limb contour deformity, with or without lymphedema.

The heterogeneity of the Klippel–Feil syndrome has made it difficult to outline the diagnosis as well as the prognosis classes for this disease. Because of this, it has complicated the exact explanation of the genetic cause of the syndrome.

The prognosis for most individuals with KFS is good if the disorder is treated early on and appropriately. Activities that can injure the neck should be avoided, as it may contribute to further damage. Other diseases associated with the syndrome can be fatal if not treated, or if found too late to be treatable.

To treat the trigonocephaly, expanding the distance between orbits using springs seems to work. It allows enough space for the brain to grow and it creates a normal horizontal axis of the orbits and supraorbital bar. The endoscopic surgery started to become popular since the early 90's, but it has some technical limitations (only strip cranictomy is possible). There have been few attempts to go beyond the limits.

Aesthetic outcomes of metopic surgery have been good. Surgery does not have a perfect outcome because there will most likely be minor irregularities. Sometimes reoperations are needed for the severe cases. Trying to hollow out the temporal, and the hypoterlorism are very hard to correct. The hypotelorism usually stays not corrected and in order to correct the temporal hollowing, a second operation is most likely needed.

The physical abnormalities resulting from SCS are typically mild and only require a minor surgical procedure or no procedure at all. One of the common symptoms of SCS is the development of short (brachydactyly), webbed fingers and broad toes (syndactyly). These characteristics do not cause any problems to the function of the hands or feet, and thus, no medical procedure is required to fix the abnormalities, unless the patient requests it. Webbing of the fingers may affect the base of the fingers, resulting in delayed hand growth during childhood, but this contributes no functional impairments. Sometimes, individuals with SCS develop broad toes because the bones at the ends of the toes are duplicating themselves. This is especially seen in the big toe, but requires no surgical intervention because it doesn't negatively affect the overall function of the foot. Individuals with these toe abnormalities walk normally and can wear normal footwear.

In more severe cases, frequent surgeries and clinical monitoring are required throughout development. A child born with asymmetrical unilateral coronal synostosis should undergo cranioplasty within its first year of life in order to prevent increased intracranial pressure and to prevent progressive facial asymmetry. Cranioplasty is a surgical procedure to correct prematurely fused cranial bones. The surgery acts to reconstruct and reposition the bones and sutures in order to promote the most normal growth. Cranioplasty is necessary in order to continue to grow and is important for two main reasons. First of all, the skull needs to be able to accommodate the growing brain following childbirth, which it can't because the skull doesn't grow as fast as the brain as long as the sutures remain fused. This results in an increase in pressure surrounding the brain and inhibits the brain from growing, causing the individual to experience significant problems, and if left untreated can eventually lead to death. Secondly, cranioplasty may be required for appearance purposes. This is especially the case in individuals with asymmetrical unilateral coronal synostosis, which requires reconstructive surgery of the face and skull. If cranioplasty is not performed, especially in individuals with unilateral coronal synostosis, then facial asymmetry will get worse and worse over time, which is why cranioplasty should be performed as soon as possible.

Surgery may also be required in individuals with vision problems. Vision problems usually arise due to a lack of space in the eye orbit and skull because of the abnormal bone structure of the face. Decreased space may also lead to abnormal or missing tear ducts and nerve damage. Reconstructive surgery is usually required in order to increase cranial space, correct tear duct stenosis, and/or correct ptosis of the eyelids in order to prevent amblyopia (lazy eye).

Midfacial surgery may also be required during early childhood to correct respiratory problems, dental malocclusion, and swallowing difficulties. A cleft palate is also corrected with surgery, and may involve the use of tympanostomy tubes. If needed, an individual will undergo orthognathic treatment and/or orthodontic treatment after facial development is complete. Since hearing loss is frequently associated with SCS, it is recommended that audiology screening persist throughout childhood.

After cranial reconstructive surgery, a child may be required to wear a molding helmet or some other form of head protection until the cranial bones set into place. This typically takes about three months and depends on the child's age and the severity of the condition. Following recovery, individuals with SCS look and act completely normal, so no one would even be able to tell that they have SCS.

Surgery is needed to prevent the closing of the coronal sutures from damaging brain development. In particular, surgeries for the LeFort III or monobloc midface distraction osteogenesis which detaches the midface or the entire upper face, respectively, from the rest of the skull, are performed in order to reposition them in the correct plane. These surgeries are performed by both plastic and oral and maxillofacial (OMS) surgeons, often in collaboration.

There is no known cure for Ehlers–Danlos syndrome. Treatment is palliative. Close monitoring of the cardiovascular system, physiotherapy, occupational therapy, and orthopedic instruments (e.g., wheelchairs, bracing, casting) may be helpful. This can help with stabilizing the joints and prevent injury. Orthopedic instruments are helpful for the prevention of further joint damage, especially for long distances, although it is advised that individuals not become entirely dependent on them until there are no other options for mobility. One should avoid activities that cause the joint to lock or overextend.

A physician may prescribe casting to stabilize joints. Physicians may refer a patient to an orthotist for orthotic treatment (bracing). Physicians may also consult a physical and/or occupational therapist to help strengthen muscles and to teach people how to properly use and preserve their joints.

There are different types of physiotherapy. Aquatic therapy promotes muscular development and coordination. With manual therapy, the joint will be gently mobilized within the range of motion and/or manipulations.

If conservative therapy is not helpful, surgical repair of joints may be necessary. Medication to decrease pain or manage cardiac, digestive, or other related conditions may be prescribed. To decrease bruising and improve wound healing, some patients have responded to ascorbic acid (vitamin C). Special precautions are often taken by medical care workers because of the sheer amount of complications that tend to arise in EDS patients. In Vascular EDS, signs of chest or abdominal pain are to be considered trauma situations.

In general, medical intervention is limited to symptomatic therapy. Before pregnancy, patients with EDS should have genetic counseling and familiarize themselves with the risks to their own bodies that pregnancy poses. Children with EDS should be provided with information about the disorder so they can understand why contact sports and other physically stressful activities should be avoided. Children should be taught early on that demonstrating the unusual positions they can maintain due to loose joints should not be done as this may cause early degeneration of the joints. Patients may find it hard to cope with the drawbacks of the disease. In this case, emotional support and behavioral and psychological therapy can be useful. Support groups can be immensely helpful for patients dealing with major lifestyle changes and poor health. Family members, teachers, and friends should be informed about EDS so they can accept and assist the child.

Depending on the severity of the deformities, the treatment may include the amputation of the foot or part of the leg, lengthening of the femur, extension prosthesis, or custom shoe lifts. Amputation usually requires the use of prosthesis. Another alternative is a rotationplasty procedure, also known as Van Ness surgery. In this situation the foot and ankle are surgically removed, then attached to the femur. This creates a functional "knee joint". This allows the patient to be fit with a below knee prosthesis vs a traditional above knee prosthesis.

In less severe cases, the use of an Ilizarov apparatus can be successful in conjunction with hip and knee surgeries (depending on the status of the femoral head/kneecap) to extend the femur length to normal ranges. This method of treatment can be problematic in that the Ilizarov might need to be applied both during early childhood (to keep the femur from being extremely short at the onset of growth) and after puberty (to match leg lengths after growth has ended). The clear benefit of this approach, however, is that no prosthetics are needed and at the conclusion of surgical procedures the patient will not be biologically or anatomically different from a person born without PFFD.
