Intramedullary and extramedullary fixation methods are widely used to treat unstable femoral intertrochanteric fractures, but the optimal surgical method remains controversial. The aim of this study was to estimate the outcomes of intramedullary fixation versus extramedullary fixation in treating unstable femoral intertrochanteric fractures. ⋯ Our meta-analysis of 11 prospective randomized controlled trials suggested: no obvious discrepancies were found in adverse events, operative time, blood transfusion, and hospital stay between intramedullary and extramedullary fixations. Given the better results of intramedullary fixation in terms of functional scores and blood loss, we recommend the intramedullary fixation technique in treating unstable femoral intertrochanteric fractures. Large multi-center RCTs, which focused on unstable femoral intertrochanteric fractures, are needed to evaluate the efficiency of alternative internal fixation strategies in the future.

The purpose of this study was to describe and evaluate the clinical application of the technique of interlocking intramedullary (IM) nailing via an entry point at the tip of greater trochanter using a specially designed femoral hollow trephine to stabilize diaphyseal fractures of the femur. ⋯ These results indicate that the technique of use of IM nailing with the femoral hollow trephine significantly decreases the occurrence of nonunion in femoral shaft fractures.

The treatment of large bone defects represents a significant challenge for orthopaedic surgeons. In recent years, biologic agents have also been used to further improve bone healing. Among these, platelet-rich plasma (PRP) is the most exploited strategy. The aim of the present study was to systematically review the available literature to identify: 1) preclinical in-vivo results supporting the rational of PRP use for bone healing; 2) evidence from the clinical practice on the actual clinical benefit of PRP for the treatment of fractures and complications such as delayed unions and non-unions. ⋯ Overall, the available literature presents major limitations in terms of low quality and extreme heterogeneity, which hamper the possibility to optimize PRP treatment and translate it into a real clinical benefit despite positive preclinical findings on its biological potential to favour bone healing.

A correlation between soft tissue thickness and osteoporosis has been suggested. We aimed to estimate if a low body mass index (BMI) and/or a decrease of skin thickness could estimate the risk of contra-lateral hip fracture. ⋯ A low BMI and a decreased skin thickness increase independently the risk of fractures by three times. When associated, they increase the risk of fracture risk by five times. This combination had a sensitivity at 71 % and a specificity at 90 % for predicting hip fracture.

Early stage adult acquired flatfoot deformity (AAFD) is traditionally treated with osteotomy and tendon transfer. Despite a high success rate, the long recovery time and associated morbidity are not sufficient. This study aims to evaluate the functional and radiological outcomes following the use of the arthroereisis screw with tendoscopic delivered PRP for early stage AAFD. ⋯ This study elucidates the successful implementation of a less invasive approach to stage IIa AAFD. Through the use of a subtalar arthroereisis screw, PTT tendoscopy, and PRP injection, clinical and radiographic outcomes were improved.
