MADELUNG DEFORMITY:

MADELUNG DEFORMITY

Slide 2:

In this deformity the lower radius curves forwards, carrying with it the carpus and hand but leaving the lower ulna sticking out as lump on the back of the wrist. It may be congenital or post-traumatic.

Slide 3:

The congenital disorder may appear as an isolated entity or as part of a generalized dysplasia; although the abnormality is present at birth, the deformity is rarely seen before the age of 10 years, after which it increases until growth is complete. Function is usually excellent.

TREATMENT:

TREATMENT If deformity is severe the lower the lower end of the ulna may be excised (Darrach’s procedure) this is sometimes combined with osteotomy of the radius. Excision of the physeal tether and replacement with a free fat graft is an alternative.
