Intramedullary nails are the common treatment options for femoral intertrochanteric fractures. However, aseptic loosening is considered to be one of the primary forms of failure that can be caused by the stress shielding between the bone and implants. The matching in mechanical properties of implant and bone is a key issue to prevent this failure. ⋯ Compared with traditional metal intramedullary nails, PEEK and FG implants might increase von Mises stress along the same path in the proximal femur. The results showed that PEEK and FG intramedullary nails obviously changed the stress distributions in the bone and reduced stress shielding. This finding indicated that PEEK and FG intramedullary nails have the potential to become alternatives to the conventional metal intramedullary nails.

Intramedullary nailing (IMN) is currently considered the gold standard in the surgical treatment of tibial shaft fractures in adult patients. In this case-control comparative study, we aimed to compare the efficacy of minimally invasive plate osteosynthesis (MIPO) and IMN in treating tibial shaft fractures. ⋯ No discrepancy was found in radiological and clinical outcomes between IMN and MIPO for tibial shaft fractures. It can be concluded that both IMN and MIPO are equally effective treatment modalities for tibial shaft fractures.

Early mortality following hip fracture surgery remains a significant issue with a much studied, multifactorial aetiology. This study designed to test the variables affecting 30 day mortality in a socially deprived cohort against national models, and secondarily aimed to uncover and quantify new risk factors. ⋯ This study has confirmed the NHFD casemix adjusted model is a fair barometer for units treating a socially deprived cohort. It also has shown a clear differentiation between risk conveyed by delay to theatre for clinical reasons and suggests delay for non-clinical reasons, although clearly not desired, may not have a significant effect on death rate. Finally, it both amplifies and prompts further investigation into the potential benefit of early mobilisation.

Percutaneous fixation of Lisfranc injuries is potentially less invasive to traditional open techniques but evidence of any clinical benefit is lacking. The aim of this study is to compare the clinical outcomes of percutaneous reduction and internal fixation (PRIF) of low energy Lisfranc injuries with a matched, control group of patients treated with ORIF. ⋯ PRIF of low energy Lisfranc injures is a safe, minimally invasive technique and is associated with better mid-term clinical outcomes compared to ORIF.

The objective of this study was to compare the outcomes and complications of patients who underwent either the calcaneal skeletal traction (CST) or the elastic intramedullary nails (EIN) procedure. ⋯ Both EIN and CST patients showed similar treatment outcomes. Hence, not only the characteristics of the patient and fracture, but also the individual's situation and expectation should be considered when choosing the best approach.
