TNF receptor-associated factors (TRAFs) −6 and −3 regulate RANKL and TNF signaling in osteoclast precursors (OCPs), but they can have opposing effects, and it is not known if their functions are inter-dependent. For example, TRAF6 is required for RANKL/RANK-induced osteoclastogenesis, while TRAF3 limits both RANKL- and TNF-induced osteoclastogenesis through proteasomal degradation of NF-κB-inducing kinase; and inhibition of autophagic degradation of TRAF3 by c...

Children with cerebral palsy who are unable to walk independently are prone to lower limb muscle weakness which contributes to pain, deformity and functional loss. As a result of these motor difficulties the children are less physically active than their unimpaired peers and subsequently at greater risk of reduced bone density. This pilot study introduced a novel mobility device, running bikes, to a group of non-ambulant children with cerebral palsy to investigate if it was a ...

Objectives: Children with Perthes disease may present with altered walking patterns even at the healed stage of the disease. The aim of the study was to assess the walking endurance, fatiguability and gait changes of children with healed Perthes disease, and to determine if walking endurance is associated with hip function and quality of life.Methods: Fifty-one children (38 males) aged 8–16 years with >3 years post-diagnosis of Perthes disease c...

Metatropic dysplasia (MD) was first described by Maroteaux et al. in 1966. Its name was derived from the Greek word metatropos which means ‘changing pattern’ because individuals with this diagnosis begin life with a short-limbed dysplasia and a long trunk with narrow chest, and over time their dysplasia becomes short-trunked due to progressive kyphoscoliosis1. It is now recognized that MD is caused by gain-of-function mutations in transie...
