Madelung's deformity

 

 

madelungs

 

Definition

 

Growth arrest of the ulna and volar aspects of the distal radius

 

Progressive ulnar and volar tilt of distal radial surface

 

Epidemiology

 

Rare

 

Autosomal dominant with incomplete penetrance

- more common in females

- usually bilateral

 

Etiology

 

Volar-ulnar radial physeal arrest

 

Carpal tether / Vicker's ligament

 

Vicker's ligament

 

Vickers ligament

 

Anatomical variant of volar radiocarpal ligament

- thick cord / fibrous band

- radial metaphysis proximal to radial epiphysis

- attaches to lunate and TFCC

 

Farr et al J Hand Surg Eur 2021

- 75 operative cases of Madelung's

- Vicker's ligament present in 85%

 

Association

 

Turner's Syndrome (45 X / XO)

 

DIfferential diagnosis

 

Post traumatic distal radial growth arrest

Enchondromatosis (Ollier's)

Hereditary Multiple Exostoses

 

Clinical

 

Palmar inclination of the wrist with prominent ulna

 

Not apparent in childhood - becomes obvious after adolescent growth spurt

 

Reduced dorsiflexion +/- rotation

 

Commonly asymptomatic with good function

 

X-ray

 

 

madelungs

 

Increased obliquity of the distal radius

Dorsal subluxation of ulna 

Inverted triangle shape of proximal carpal row

Lunate subluxed between radius and ulna

 

MRI

 

Vicker's ligament

 

Operative management

 

Indications

 

Pain / reduced function

 

Cosmetic deformity 

 

Options

 

Skeletally immature

 

Excision Vicker's ligament + Epiphysiolysis of fused physis with fat graft

Epiphysiodeses of distal ulna

 

Otte et al J Hand Surg Am 2019

- 12 wrists with Madelung's deformity

- mean age 7.5 years

- Vicker ligament release and radial physiolysis

- 83% improvement radial inclination

- no worsening deformity 

 

Skeletally mature

 

Distal radius osteotomy +/- ulna shortening osteotomy

 

Harley et al JBJS Am 2000

- dome osteotomy + ligament release in 26 Madelung's deformity

- mean age 13

- improvement in pain, cosmetic appearance, and range of motion
