Presentation
-short limb gait

Examination:
-gait
-supine position
-Galleazi test
-Bryan triangle
-measurement:
-true length - square the pelvis
-apparent length - parallel the limb

Common Qs:
1. what is the effect of fixed adduction/abduction deformity?
-apparent shortening/lengthening of the limb.

2.What are the causes of apparent shortening?
-spine and pelvic problem
-spine (eg.scoliosis) pelvis ( eg. fixed adduction deformity)

3.Give example of equal true length but shortening of apparent length?
-# hemipelvis.
-scolisosis

4.How do you manage apparent shortening?
-treat the cause eg treat scolisosis, pelvic fracture etc.

5.How to treat true shortening?
-<2cm - no treatment, compensated by pelvis.
-2-5cm - Shoe raise
->5cm - (Bone lengthening eg,Illizarov fixator, bone grafting )
-in children, consider epiphysiodesis(of the contralateral side)

6.What are the complications of limb length inequality?
-early osteoarthritis of the affected joint
-early low back pain.
