“…Birner et al [ 25 ] performed a randomized analysis of 500 patients treated at 110 hospital centers using retrograde femoral nailing with SFN® for femoral midshaft fractures, determining an incidence of malalignment > 5° in 9.4% of the cases and obtained satisfactory postoperative results in the majority of patients, comparable to use the SSN® in the treatment of femoral midshaft fractures in LIMC.…”

Purpose Femoral fractures are common in low and middle-income countries (LMIC), predominantly caused by high-energy trauma. The surgical implant generation network (SIGN®) program offers two different intramedullary nails in LMIC which are designed to be used without image intensifier free of charge for the patients: the SIGN standard nail (SSN®) and the SIGN Fin nail (SFN®). This study aimed to compare the results of the SSN® and the SFN® for the treatment of middle and distal shaft femoral fractures through a retrograde approach. Material and Methods This was a retrospective, descriptive, and non-experimental study including all consecutive patients who underwent surgical management of middle or distal shaft femoral fracture between January 2017 and May 2022 in an NGO hospital located in Freetown, Sierra Leone. The duration of surgery, type of reduction, complications like screw loosening, implant migration, anterior knee pain and non-union rate at six months of follow up were evaluated. Results A total of 122 patients were included in the study. Group A: 60 patients were managed with SSN® and Group B: 62 patients with SFN®. The mean operative time was 104 min with SSN® and 78 with SFN® (p < 0.001). Open reduction of the fracture was necessary in ten (16.7%) patients with SSN® and 12 (19.4%) patients treated with SFN® (p = 0.69). Non-union was observed in one (1.7%) patient with SSN® and two (3.2%) patients with SFN® (p = 0.57). Conclusions Both options seem equally effective in treating midshaft and distal femoral shaft fractures. The SFN® reduces the surgical time, due to this fact, in polytraumatized patients, patients with bilateral femur fracture or patients with ipsilateral tibia fracture, it can be considered as the best option to be used. There was no statistical difference in the complications presented by the two groups.

This paper presents the experimental position and force testing of a 3-armed 6-DOF Parallel Robot, Robossis, that is specifically designed for the application of long-bone femur fracture surgery. Current surgical techniques require a significant amount of time and effort to restore the fractured femur fragments’ length, alignment and rotation. To address these issues, the Robossis system will facilitate the femur fracture surgical procedure and oppose the large traction forces/torques of the muscle groups surrounding the femur. As such, Robossis would subsequently improve patient outcomes by eliminating intraoperative injuries, reducing radiation exposure from X-rays during surgery and decreasing the likelihood of follow-up operations. Specifically, in this paper, we study the accuracy of the Robossis system while moving in the operational workspace under free and simulated traction loads of ([Formula: see text]–1100[Formula: see text]N). Experimental testing in this study demonstrates that Robossis can reach the most extreme points in the workspace, as defined by the theoretical workspace, while maintaining minimal deviation from those points with an average deviation of 0.324[Formula: see text]mm. Furthermore, the force testing experiment shows that Robossis can counteract loads that are clinically relevant to restoring the fractured femur fragments’ length, alignment and rotation. In addition, we study the accuracy of Robossis motion while coupled with the master controller Sigma 7. The results show that Robossis can follow the desired trajectory in real-time with an average error of less than 1[Formula: see text]mm. To conclude, these results further establish the ability of the Robossis system to facilitate the femur fracture surgical procedure and eliminate limitations faced with the current surgical techniques.

Fractures of the proximal extremity of the femur are some of the most common injuries treated by orthopedic surgeons, often associated with life-threatening polytrauma. Trochanteric fractures have an increased incidence, which is becoming more common due to the aging population. Femoral neck fractures are a particular type of intracapsular hip fracture, and the location of the junction makes the femoral neck prone to fracture. Fractures of the femoral shaft are found in approximately 6-9% of cases of femoral neck fractures. The management of these fractures is interdisciplinary, but in most cases, it requires surgical treatment to allow rapid elevation and recovery of autonomy. The present study is retrospective in which 140 cases of fracture of the upper femur extremity collected at the trauma department of Naousa and Kilkis Hospital over 4 years from December 2018 to December 2022 were analyzed, processed, and reviewed with a minimum follow-up of 6 months. The purpose of this article is to analyze the frequency of various types of fractures of the proximal extremity of the femur and to identify the etiological factors that contribute to these injuries, thus providing a comprehensive understanding of these traumatic events to treat them. The study showed that there is a preponderance of trochanteric fractures, with an increased frequency in the 75-89 age group and a predominance of femoral neck fractures in women, mainly caused by falls. External surgical approaches, standard gamma nail, and bipolar treatment had "excellent/good" functional results reflecting the success of the surgical interventions. The high frequency of anatomical reductions underlines the attention paid to the quality of the procedures.
