I. Failure of formation of parts (arrest of development)
A. Transverse arrest (common levels are upper third of
forearm, wrist, metacarpal, phalangeal)
B. Longitudinal arrest (including phocomelia, radial/ulnar club
hands, typical cleft hand, atypical cleft hand otherwise
referred to as part of the spectrum of symbrachydactyly)

III. Duplication
IV. Overgrowth
V. Undergrowth (thumb hypoplasia, Madelung's deformity
(abnormal distal radial growth)
VI. Congenital constriction band syndrome
VII. Generalised skeletal abnormalities.
9. Diagnosis before birth
Antenatal diagnosis by ultrasound is increasingly possible,
particularly in cases of aplasia.
This will prepare the parents for the deficiency before birth.
10. CLUB HAND
• Club hand deformites are classified into two main
categories radial and ulnar.
• Radial club hand
• Ulnar club hand
12. RADIAL CLUB HAND
• Radial club hand includes a wide spectrum of disorders that
encompass absent thumb, thumb hypoplasia, thin first
metacarpal and absent radius.
• Radial club hand is frequently syndromatic
• 1733
13. RADIAL CLUB HAND
Well-developed arm bud - 28-30 days
males : females (3:2)
1:55000 to 1:100000 live births
maternal drug exposure, compression of the uterus,
vascular injury, Apical Ectodermal Ridge (AER)
15. RADIAL CLUB HAND
Type I: Short distal radius - mildest type,
Type II: Hypoplastic radius,
Type III: Partial absence of radius,
Type IV: Total absence of radius - most common variant.

19. RADIAL CLUB HAND
TREATMENT :
slow distraction by external fixation
hand can be aligned on the forearm
preserve some wrist movement
index finger is pollicised.
20. Ulnar club hand
• Ulnar club hand is much less frequent than radial club hand
• ranges from mild deviation of hand on the ulnar side of
forearm to complete absence of ulna.
• ulnar club hand is usually isolated anomaly
22. Madelung deformity
A growth disturbance in the
volar-ulnar distal radial physis
volar and ulnar tilted distal radial
articular surface,
volar translation of the hand and
wrist,
a dorsally prominent distal ulna.
24. Madelung deformity

pain, decreased range of motion, and deformity.
genetic etiology and is associated with mesomelic dwarfism
and a mutation on the X chromosome.
Surgery addressing the deforming bony and ligamentous
lesions, correcting the abnormal position of the radial
articular surface, and equalizing the longitudinal levels of
the distal radius and ulna
27. Apert's syndrome
• Apert syndrome is a form of acrocephalosyndactyly, a
congenital disorder characterized by malformations of the
skull, face, hands and feet.
• It is classified as a branchial arch syndrome, affecting the
first branchial (or pharyngeal) arch, the precursor of the
maxilla and mandible
• Disturbances in the development of the branchial arches in
fetal development create lasting and widespread effects.
31. CLEFT HAND
• Typical cleft hand is usually bilateral, often affecting the
feet as well
• AD
• The deficiency is maximal on the ulnar size, leaving in
severe cases only a hypoplastic thumb.
37. THUMB HYPOPLASIA AND APLASIA
• no trapezium or trapeziometacarpal joint.
• Hypoplastic thumbs can be
stabilised and given more
movement by tendon
transfers.
• The operation of choice is to
pollicise the index finger
