Aims. Periprosthetic fracture is a significant complication of total
hip and knee arthroplasty. This study aimed to describe the survival
of patients sustaining periprosthetic femoral fractures and compare
this with that of the general population, as well as to identify
the factors that influence survival. Patients and Methods. A total of 151 patients (women: men 116:35, mean

Objectives. Cellular movement and relocalisation are important for many physiologic properties. Local mesenchymal stem cells (MSCs) from injured tissues and circulating MSCs aid in fracture healing. Cytokines and chemokines such as Stromal cell-derived factor 1(SDF-1) and its receptor chemokine receptor type 4 (CXCR4) play important roles in maintaining mobilisation, trafficking and homing of stem cells from bone marrow to the site of injury. We investigated the differences in migration of MSCs from the femurs of young, adult and ovariectomised (OVX) rats and the effect of CXCR4 over-expression on their migration. Methods. MSCs from young, adult and OVX rats were put in a Boyden chamber to establish their migration towards SDF-1. This was compared with MSCs transfected with CXCR4, as well as MSCs differentiated to osteoblasts. Results. MSCs from OVX rats migrate significantly (p < 0.05) less towards SDF-1 (9%, . sd. 5%) compared with MSCs from adult (15%, . sd. 3%) and young rats (25%, . sd. 4%). Cells transfected with CXCR4 migrated significantly more towards SDF-1 compared with non-transfected cells, irrespective of whether these cells were from OVX (26.5%, . sd. 4%), young (47%, . sd. 17%) or adult (21%, . sd. 4%) rats. Transfected MSCs differentiated to osteoblasts express CXCR4 but do not migrate towards SDF-1. Conclusions. MSC migration is impaired by

To compare the early management and mortality of older patients
sustaining major orthopaedic trauma with that of a younger population
with similar injuries. The Trauma Audit Research Network database was reviewed to identify
eligible patients admitted between April 2012 and June 2015. Distribution
and severity of injury, interventions, comorbidity, critical care
episodes and mortality were recorded. The population was divided
into young (64 years or younger) and older (65 years and older) patients.Aims

Using a prospective database of 1309 displaced acetabular fractures gathered between 1980 and 2007, we calculated the annual mean

Several authors have suggested that the final
five weeks of gestation are a critical period for the development
of the hip. In order to test the hypothesis that gestational age
at birth may influence the development of the hip joint, we analysed
the sonographic findings in 1992 hips (in 996 term newborns) with
no risk factor for developmental dysplasia of the hip. The 996 infants
were born at a mean gestational
