“…The study was directed at investigating the stress state arising at the contact between the expansion flanges and the medullary canal, defining the properties of the bone-implant contact zone and quantifying the stresses. The results highlighted that the stress peaks due to the contact were detectable at limited points on the extremities of the flanges and the stress state was very high on the internal part section of bones, which explained why the bone-implant contact was inefficient in the distal expansion system [ 77 ]. For the clinical practices, they suggested that the intramedullary nail being chosen should be compatible with the length of the humerus being treated.…”

Proximal humeral fractures are common and most challenging, due to the complexity of the glenohumeral joint, especially in the geriatric population with impacted fractures, that the development of implants continues because currently the problems with their fixation are not solved. Pre-, intra-, and postoperative assessments are crucial in management of those patients. Finite element analysis, as one of the valuable tools, has been implemented as an effective and noninvasive method to analyze proximal humeral fractures, providing solid evidence for management of troublesome patients. However, no review article about the applications and effects of finite element analysis in assessing proximal humeral fractures has been reported yet. This review article summarized the applications, contribution, and clinical significance of finite element analysis in assessing proximal humeral fractures. Furthermore, the limitations of finite element analysis, the difficulties of more realistic simulation, and the validation and also the creation of validated FE models were discussed. We concluded that although some advancements in proximal humeral fractures researches have been made by using finite element analysis, utility of this powerful tool for routine clinical management and adequate simulation requires more state-of-the-art studies to provide evidence and bases.

“…Specifically, such mechanisms imply the expansion of the device which gets in contact with the inner surface of the medullary canal, thus providing the distal locking. Among the used expansion mechanisms deserving to be mentioned there are: the releasing, by means of a sliding nut, of the distal ends of a bundle of curved elastic rods which constitute the nail body (see the Marchetti-Vicenzi nail, Anastopoulos et al, 2001); the spreading out of a series of anchoring flanges, controlled by the tightening of a bolt located at the distal end of the nail (see the Seidel nail, Giudice et al, 2006); the expansion of the whole nail body, consisting of a folded stainless steel shell, through the injection of a pressurized saline solution (see the Fixion nail, CarboFix Orthopedics Ltd., Herzliya, Israel). A few works dedicated to study these nails are reported in literature, most of them refer to Marchetti-Vicenzi nail (Tennant et al, 2001;Madan et al, 2003;Martínez et al, 2004) or other fixation systems (Rose et al, 2013).…”

“…For these reasons some alternative devices have been developed basing on the expansion of anchoring fins or flanges [14][15][16]. Also these solutions, nevertheless, have shown some problems related to the system stability and high stress peaks at the bone-nail interface [17].…”

In this work a new distal interlocking system has been developed which is easy to use, allows a reduction of the operating time and consequently the exposure to radiations both for surgeon and patient. The main goal of this study has been the design of a new intramedullary nail for tibial fractures able to simplify and speed up the distal locking operation phases. After a preliminary stage during which several candidate concepts have been proposed and analysed, the best solution has been developed and deeply investigated. The new system, called "expansion nail", has been firstly modelled by setting up a full parametric CAD model and, then, tested by running non linear FEM analyses to evaluate stresses and stability of the joining during normal working conditions. The new design has shown very high mechanical stability in the axial compression and torsional load cases. Since its very simple self-locking system, the new expansion intramedullary nail would reduce the operating time and the exposure to radiations for the surgeons as well as the patients.
