Ty, MD06/01/201899df5db6-d7ab-419d-bae9-56fd26c29bcdhttps://kidshealth.org/ws/RadyChildrens/en/parents/ulnar-dysplasia.html/<h3>What Is Ulnar Dysplasia?</h3> <p>Babies with ulnar dysplasia&nbsp;(also called <strong>ulnar club hand</strong>) are born with a short or missing ulnar bone.</p> <p>The ulnar <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/bones-muscles-joints.html/">bone</a> is one of the two forearm bones. The short or missing ulnar bone causes the hand and wrist to turn outward toward the pinky side of the forearm. The hand, wrist, and elbow can have changes too.</p> <h3>What Are the Signs &amp; Symptoms of Ulnar Dysplasia?</h3> <p>There are four types of ulnar dysplasia . Signs and symptoms depend on what type of ulnar club hand a child has.</p> <h4>Type I</h4> <p>This is the mildest form of ulnar dysplasia. The ulna is just a little shorter than normal and the wrist only turns out slightly.</p> <h4>Type II</h4> <p>The ulna is much smaller than normal. The other bone of the forearm (the <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/radial-dysplasia.html/">radius</a>) is bowed and the hand turns out more.</p> <h4>Type III</h4> <p>There is no ulna at all. The radius is bowed and the wrist is very turned out.</p> <h4>Type IV</h4> <p>There is no ulna at all. The wrist is very turned out, and the bones of the elbow are fused together so the elbow joint does not move well.</p> <p>In all types, the fingers may be smaller than usual or completely missing. Ulnar club hand can happen on one or both sides.</p> <h3>What Causes Ulnar Dysplasia?</h3> <p>Ulnar dysplasia happens while a baby is developing in the womb. Ulnar dysplasia also can be associated with leg growth differences.</p> <p>Sometimes it can happen as part of a <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/about-genetics.html/">genetic</a> syndrome where there are other medical problems too.</p> <h3>Who Gets Ulnar Dysplasia?</h3> <p>Any baby can be born with ulnar dysplasia. It usually does not run in families.</p> <h3>How Is Ulnar Dysplasia Diagnosed?</h3> <p>A prenatal <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/prenatal-ultrasound.html/">ultrasound</a> might show ulnar dysplasia. Otherwise, doctors diagnose it when a baby is born.</p> <p>X-rays of the bones in the hands and arms will help doctors decide on the best kind of treatment. Other tests might be done to see if the ulnar dysplasia is part of a genetic syndrome.</p> <h3>How Is Ulnar Dysplasia Treated?</h3> <p>Treatment for ulnar dysplasia depends on how severe the changes are. Treatment may include:</p> <ul> <li>exercises</li> <li><a href="https://kidshealth.org/ws/RadyChildrens/en/parents/splints.html/">splinting</a> and <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/casts.html/">casting</a> to help stretch the arm and wrist</li> <li>surgery</li> </ul> <h3>Looking Ahead</h3> <p>Even with challenges, children with ulnar dysplasia are very good about finding ways to use their hands well. Some tasks can be adapted, like having shoes with Velcro instead of laces. Work with the medical team to help your child learn what works best.</p>Displasia cubitalLos bebés con displasia cubital (también conocida como displasia ulnar) nacen con un cúbito más corto de lo normal o sin él. El acortamiento o la ausencia del cúbito hace que la mano y la muñeca se curven hacia fuera, acercando el dedo meñique al antebrazo. https://kidshealth.org/ws/RadyChildrens/es/parents/ulnar-dysplasia-esp.html/6103db7a-36ab-4972-ab8f-dfea9a47e093
Bones, Muscles, and JointsWithout bones, muscles, and joints, we couldn't stand, walk, run, or even sit. The musculoskeletal system supports our bodies, protects our organs from injury, and enables movement.https://kidshealth.org/ws/RadyChildrens/en/parents/bones-muscles-joints.html/53199934-b6d8-4854-8362-8b1dfc45c3f6
Fibular HemimeliaBabies who have fibular hemimelia are born with a short or missing fibula. Experts who treat bone problems have several options to help kids with a hemimelia.https://kidshealth.org/ws/RadyChildrens/en/parents/fibular-hemimelia.html/189e6e5d-f1a1-4c81-834c-b70ecbd77a64
Leg Length DiscrepancyLeg length discrepancy is when someone’s legs are different lengths. For a big difference or one that's likely to get worse, treatment is recommended. https://kidshealth.org/ws/RadyChildrens/en/parents/leg-length-discrepancy.html/4ca63291-1c1d-45ef-95a7-6b7717f6642d
Occupational TherapyOccupational therapy can help improve kids' cognitive, physical, and motor skills and build their self-esteem and sense of accomplishment.https://kidshealth.org/ws/RadyChildrens/en/parents/occupational-therapy.html/e6873992-af60-4bab-82d9-3bd1fe9ad5a3
PolydactylyPolydactyly is when a baby is born with an extra finger on the hand or an extra toe on the foot. It can be on one or both hands or feet.https://kidshealth.org/ws/RadyChildrens/en/parents/polydactyly.html/684055dc-071c-4973-8ce6-9281a43185ae
Radial DysplasiaBabies with radial dysplasia (also called radial club hand) are born with a short or missing radial bone. This makes the wrist turn in.https://kidshealth.org/ws/RadyChildrens/en/parents/radial-dysplasia.html/6fa65f17-f1df-47fb-8f7b-35cb8efeccb5
SymbrachydactylyBabies with symbrachydactyly are born with short often webbed fingers. Some might be missing fingers.https://kidshealth.org/ws/RadyChildrens/en/parents/symbrachydactyly.html/afe1b0ce-964d-477a-a395-e1f81141358c
SyndactylySyndactyly is when a baby is born with two or more fingers or toes joined or "webbed" together. https://kidshealth.org/ws/RadyChildrens/en/parents/syndactyly.html/5edd8317-51f6-443c-b25c-5ec74bd7218b
Thumb DuplicationBabies with thumb duplication (or thumb polydactyly) are born with an extra thumb on one or both hands. Most will have surgery to fix the problem.https://kidshealth.org/ws/RadyChildrens/en/parents/thumb-duplication.html/f0a9cba2-ac76-470e-9d43-4345a6d57493
Thumb HypoplasiaBabies with thumb hypoplasia are born with a thumb that is smaller than normal, or with the thumb missing completely.https://kidshealth.org/ws/RadyChildrens/en/parents/thumb-hypoplasia.html/c8fbf7e7-948b-4209-b1ed-e038838968e2
X-Ray Exam: ForearmA forearm X-ray can help find the causes of pain, tenderness, swelling, or deformity. It can detect broken bones, and after a broken bone has been set, help determine whether it has healed properly.https://kidshealth.org/ws/RadyChildrens/en/parents/xray-forearm.html/3f91e95a-f371-4784-a41f-4ff7e87b91d2
X-Ray Exam: HandA hand X-ray can help find the cause of pain, tenderness, swelling, and deformity. It also can detect broken bones or dislocated joints.https://kidshealth.org/ws/RadyChildrens/en/parents/xray-hand.html/64b6be7e-e187-4bd6-a004-a72afbdf6296
