Hand & Upper Extremity Differences

Expert, Compassionate Care for Kids


Little girl is examined for a hand and upper extremity condition.

The “upper extremity” is every part of the arm, from the shoulder to the fingertips. Problems of the upper extremities may also involve the muscles and bones that attach the arm to the rib cage, including the collarbone and shoulder blade. Wrist, elbow, shoulder and hand disorders and differences can have many causes, including injuries, medical conditions or conditions present at birth. No matter what the cause, at Nemours our surgeons, physical therapists and other specialists are here to give your child complete, caring treatment at every step.

Upper extremity and hand disorders can be complex in how they affect the bones, muscles, tendons, nerves and blood vessels. We see a lot of hand and upper extremity conditions — far too many to list here. The conditions we treat vary depending on the location and providers selected. Don’t see a condition listed? Call us.

  • bone or muscle tumors
  • brachial plexus/birth palsies (nerve injuries in the arm that can occur during birth)
  • broken bones and malunions (when bones don’t heal like they should)
  • cerebral palsy (a movement disorder that can cause muscle stiffness or weakness in the hand and arm)
  • congenital radial head dislocation (when a baby is born with a dislocated elbow bone)
  • growth plate injury (damage to the part of a bone that’s growing)
  • Kienbock’s disease (when a bone in the wrist collapses)
