The R3 cementless acetabular system (Smith & Nephew, Memphis, Tennessee, United States) is a modular titanium shell with an asymmetric porous titanium powder coating. It supports cross-linked polyethylene, metal and ceramic liners with several options for the femoral head component. The R3 cup was first marketed in Australia and Europe in 2007. Two recent papers have shown high failure rates of the MoM R3 system with up to 24% (Dramis et al 2014, Hothi et al 2015). There are currently no medium term clinical papers on the R3 acetabular cup. The aim of the study is to review our results of the R3 acetabular cup with a minimum of 5 year follow up.Background

Fractures of the metatarsal bones are the most frequent fracture of the foot. Up to 70% involve the fifth metatarsal bone, of which approximately eighty percent are located proximally. Low-intensity pulsed ultrasound (LIPUS) has been shown to be a useful adjunct in the treatment of delayed fractures and non unions. However, there is no study looking at the success rate of LIPUS in fifth metatarsal fracture delayed unions. The aim of our study was to investigate the use of LIPUS treatment for delayed union of fifth metatarsal fractures.Background
