Bilateral transtibial amputation with concomitant thoracolumbar vertebral collapse in a Sichuan earthquake survivor.

The devastating earthquake in Sichuan, China on 12 May 2008 left thousands of survivors requiring medical care and intensive rehabilitation. In view of this great demand, the Chinese Speaking Orthopaedic Society established the "Stand Tall" project to provide voluntary services to aid amputee victims in achieving total rehabilitation and social integration. This case report highlights the multidisciplinary rehabilitation of a girl who suffered thoracolumbar vertebral collapse and underwent bilateral transtibial amputation.

Effect of dexamethasone on cultured human tenocytes and its reversibility by platelet-derived growth factor.

Background: Many cases of tendon rupture after glucocorticoid injections have been reported in the literature. Despite previous studies on the histological and biomechanical changes in tendons after glucocorticoid injections, the role of glucocorticoid in causing tendon rupture still remains controversial. The objective of this study was to determine whether glucocorticoid has deleterious effects on the cellular metabolism and collagen production of cultured human tenocytes and the reversibility of these effects by platelet-derived growth factor-BB (PDGFBB).
