Module 55, General Orthopaedist Level

This patient is a 14 year and 6 month old black male with a one year history of progressively worsening left knee pain. The scanogram demonstrated a 4 cm leg length discrepancy, with the left shorter than the right .

Question 55A

This leg length difference is probably due to a congenital deformity.

Question 55B

The leg length difference and knee pain are probably not due to the same problem.

Question 55C

Epiphysiodesis of the longer leg is the preferred treatment for this boy.

Question 55D

This problem is usually related to a specific body habitus.

Question 55E

A trial of a 3 centimeter shoe lift would provide a good demonstration of the benefit to lengthening the short leg .
