Elder abuse is common, but many characteristics have not been well-described, including injury mechanisms and weapons in physical abuse. Better understanding of these may improve identification of elder abuse among purportedly unintentional injuries. Our goal was to describe mechanisms of injury and weapons used and their relation to injury patterns. ⋯ Physical elder abuse victims are more commonly assaulted with an abuser's body part than an object, and the mechanisms and weapons used impact patterns of injury.

Traditional tension band wire fixation (TBWF) of olecranon fractures is associated with high revision rates due to implant-related complications. The purpose of the study was to compare the strength of fixation in olecranon fractures between TBWF and an all-suture based technique. ⋯ Basic science study.

Our previous studies have demonstrated the mechanical effect of sclerosis around screw paths on the healing of femoral neck fractures (FNF) after internal fixation. Furthermore, we discussed the possibility of using bioceramic nails (BNs) to prevent sclerosis. However, all these studies were conducted under static conditions as the patient was standing on one leg, while the effect of the stress generated during movement is unknown. The purpose of this study was to evaluate the stress and displacement under dynamic stress loading conditions. ⋯ The presence of sclerosis around screw paths increases the risk of femoral head necrosis. Removal of CS has little effect on the mechanics of the femur after healing of the FNF. BNs have several advantages over conventional CSs after FNF. Replacing all internal fixations with BNs after the healing of FNF may solve the problem of sclerosis formation around CSs to improve bone reconstruction owing to their bioactivity.

Management of fragility ankle fractures in the elderly poses a surgical dilemma. An alternative to open reduction and internal fixation (ORIF) with screw and plate construct in selected elderly patients who may be significantly frail and comorbid is a tibio-talo-calcaneal (TTC) or hindfoot nail. Hindfoot nailing potentially reduces the risk of wound infection and increases likelihood of earlier return to function by allowing earlier weightbearing. The aim of this study was to examine the outcomes and complications of patients who received a hindfoot nail compared to patients who underwent an ORIF. ⋯ Hindfoot nailing was associated with an increased risk of complications and higher risk of return to the operating theatre. Despite the potential attraction of earlier weightbearing, surgeons and patients need to be aware of these potential pitfalls.

Ischemia-reperfusion(I/R) injury is an unavoidable side effect of liver surgery and transplantation. A potentially useful tool for cellular therapy and tissue engineering is adipose-derived stem cells (ADSCs).The process of autophagy is used by the cell to break down inappropriate molecules.The study's goal was to examine the impact of ADSCs on the autophagic pathway after rat hepatic ischemia-reperfusion injury. ⋯ ADSCs reduced the excessive level of autophagy and structural damage to hepatocytes and the pathological alterations in the liver after ıschemia-reperfusion injury.
