Finger syndactyly- MedGen UID:
- 65139
- •Concept ID:
- C0221352
- •
- Congenital Abnormality
Webbing or fusion of the fingers, involving soft parts only or including bone structure. Bony fusions are referred to as "bony" Syndactyly if the fusion occurs in a radio-ulnar axis. Fusions of bones of the fingers in a proximo-distal axis are referred to as "Symphalangism".
Short middle phalanx of the 5th finger- MedGen UID:
- 322335
- •Concept ID:
- C1834060
- •
- Anatomical Abnormality
Hypoplastic/small middle phalanx of the fifth finger.
4-5 toe syndactyly- MedGen UID:
- 324891
- •Concept ID:
- C1837836
- •
- Finding
Syndactyly with fusion of toes four and five.
Clinodactyly of the 5th finger- MedGen UID:
- 340456
- •Concept ID:
- C1850049
- •
- Congenital Abnormality
Clinodactyly refers to a bending or curvature of the fifth finger in the radial direction (i.e., towards the 4th finger).
3-4 finger syndactyly- MedGen UID:
- 346463
- •Concept ID:
- C1856889
- •
- Finding
Syndactyly with fusion of fingers three and four.
6 metacarpals- MedGen UID:
- 348337
- •Concept ID:
- C1861360
- •
- Finding
Y-shaped metacarpals- MedGen UID:
- 348341
- •Concept ID:
- C1861373
- •
- Finding
Y-shaped metacarpals are the result of a partial fusion of two metacarpal bones, with the two arms of the Y pointing in the distal direction. Y-shaped metacarpals may be seen in combination with polydactyly.
2nd-5th toe middle phalangeal hypoplasia- MedGen UID:
- 348853
- •Concept ID:
- C1861376
- •
- Finding
Broad hallux- MedGen UID:
- 401165
- •Concept ID:
- C1867131
- •
- Finding
Visible increase in width of the hallux without an increase in the dorso-ventral dimension.
Postaxial foot polydactyly- MedGen UID:
- 384489
- •Concept ID:
- C2112129
- •
- Finding
Polydactyly of the foot most commonly refers to the presence of six toes on one foot. Postaxial polydactyly affects the lateral ray and the duplication may range from a well-formed articulated digit to a rudimentary digit.
Preaxial foot polydactyly- MedGen UID:
- 389171
- •Concept ID:
- C2112942
- •
- Finding
Duplication of all or part of the first ray.
Mesoaxial hand polydactyly- MedGen UID:
- 893020
- •Concept ID:
- C4021606
- •
- Anatomical Abnormality
The presence of a supernumerary finger (not a thumb) involving the third or fourth metacarpal with associated osseous syndactyly.
Contracture of the proximal interphalangeal joint of the 5th finger- MedGen UID:
- 767526
- •Concept ID:
- C3554612
- •
- Finding
Proximal interphalangeal (PIP) flexion deformity of the little finger. That is, the PIP joint of a little finger is bent (flexed) and cannot be straightened actively or passively. It is thus a chronic loss of joint motion due to structural changes in muscle, tendons, ligaments, or skin that prevents normal movement.
