      - Hypoplastic Thumb
      - Lobster Hand
      - Macrodactyly:

      - Congenital Trigger Thumb
      - Radioulnar Synostosis

- Hemihypertrophy:
    - see macrodactyly:
    - have a significant incidence of Wilms' tumor;
    - for this reason, abdominal ultrasonography should not only be part of initial evaluation but should be performed yearly during the patients' growing years;
    - syndromes associated with hemihypertrophy:
          - Beckwith-Wiedemann syndrome
          - neurofibromatosis
          - Klippel-Trénaunay-Weber syndrome
          - Proteus syndrome

- Brachydactyly:
    - brachydactyly type C:
          - an autosomal dominant disorder with markedly variable penetrance;
          - incomplete gene expression:
                - shortening limited to the middle phalanges and the first metacarpal;
                - elongation of the radial side of the base of the second proximal phalanx;
          - complete gene expression:
                - shortening of all the metacarpals (thumb most affected)
                - brachymesophalangy (shortening of the middle phalanges);
                - shortening of the proximal phalanges of the index and middle fingers, with the proximal phalanges of the ring and small fingers of normal length;
                - elongation of the radial side of the base of the second proximal phalanx resulting in a trapezoidal shaped epiphysis;
                - ulnar deviation at the second and third MP joints and hypersegmentation (extra phalanx) of the index and middle fingers.
