To assess the success of proximal cephalomedullary nailing operations for treating trochanteric fractures, surgeons utilize 2D fluoroscopy to observe the relative positions of the femoral head and the implant. One distance-based risk parameter, observed from the AP and Lateral projections, is the Tip-Surface Distance(TSD) that dictates how close to the outer cortex should the implant tip be residing to avoid post-surgical complications such as cut-out or joint penetration. In this study, the safety and the accuracy of the orthogonal fluoroscopic imaging were evaluated.

A femoral head model was created and the risk zone was defined as a hemispherical shell of 5mm thickness beneath the subchondral cortex, which should not be violated during screw insertion. The remaining hemisphere beneath the risk zone was designated as the safe zone. To assess the effect of head size, each simulation was conducted for 34, 47, and 60mm diameter(D
) femoral heads. The rate of safe zone violation was calculated for all possmay be used to check the security of the implantation.
Depending solely on the orthogonal fluoroscopic images is not a safe and accurate technique for assessing joint penetration risk during proximal femoral fixation due to the spherical geometry of the femoral head. The screw tip can lie completely outside of the femoral head even when it appears inside, in both orthogonal fluoroscopic views. Evidently, when using TSD, more stringent distance limits should be chosen, contrary to the recommended 5 mm limit. find more Our safety maps for TSD combinations may be used to check the security of the implantation.
There has been an increased interest in the role of preoperative posterior tilt, as measured on lateral radiographs, on the outcomes of internal fixation of non-displaced femoral neck fractures (FNF). The goal was to assess the available evidence for this in the literature.

PRISMA guidelines were followed. PubMed, Embase and Cochrane were searched on June 10th, 2020 for studies assessing the role of posterior tilt on outcomes of internal fixation of non-displaced FNF. Primary outcomes were non-union and fixation failure, avascular necrosis (AVN), treatment failure, and reoperation (excluding symptomatic hardware removal). Outcomes were reported in Odds Ratio (OR) with 95% confidence intervals [CI].

Fourteen studies and 3729 patients were included (mean age 76 years, 72% female, mean follow-up 25 months). Moderate evidence was noted for the following patients with greater preoperative posterior tilt had an increased risk of non-union and fixation failure (OR 2.4 [1.3 - 4.3]; p=0.006), no increased risk o (OR 2.4 [1.3 - 4.3]; p = 0.006), no increased risk of AVN (p = 0.550), an increased risk of treatment failure (OR 6.0 [2.2 - 15.9]; p less then 0.001) and reoperation (OR 2.5 [1.4 - 4.4]; p = 0.002). Furthermore, a greater preoperative tilt of 9.0° [4.1° - 13.9°] for treatment failure and 6.1° [3.7° - 8.5°] (p less then 0.001) for reoperation were noted in the unsuccessfully treated groups when compared to the successfully treated groups. Four studies found a threshold for posterior tilt ranging from 7° to 20° CONCLUSION There is moderate evidence that patients with non-displaced FNF and greater tilt have an increased risk of unsuccessful outcomes following internal fixation. Older patients with a preoperative tilt of ≥20° might benefit from arthroplasty surgery, although studies assessing the optimal threshold are needed.Presenting to the fracture clinic carries economic, social and societal consequences. The virtual fracture clinic (VFC) has proven to be a safe, patient-focused, cost-effective means of delivering trauma care, whilst reducing unnecessary clinic attendances. Within our institution, a Satellite VFC was established, so as to accommodate an offsite referring emergency department. The VFC database was accessed to identify the first 500 patients who were referred to the Satellite VFC. The decision made for each patient, the rate of returns to the clinic, and the rate of referrals requiring surgical intervention, following discussion at the VFC, ,were identified. A cost analysis and cost comparison was carried out between the Satellite VFC and the traditional "face to face" fracture clinic. There were 500 patients referred to the Satellite VFC within the study period. Of such patients, 288 (58%) were discharged directly following review at the Satellite VFC, 141 patients (28%) were referred to physiotherapy, 50 (10%) were redirected to the trauma clinic, 11 (2%) were sent directly to hand therapy, and 10 (2%) were sent to the ED review clinic. Patients who returned to the fracture clinic accounted for 3.8% of all referrals, and 0.2% of all referrals necessitated surgical intervention. This pilot initiative saved the Dublin Midlands Hospital Group over €50,000. The Satellite VFC is the first of its kind in the literature. Rural communities worldwide would benefit from remote orthopaedic management of suitable fracture patterns. The true value of the Satellite VFC process comes from its use of robust patient care pathways, rationalising resource use and minimising patient travel, whilst demonstrating reliable outcomes and promoting safety.Implant loosening, bone healing failure, implant-associated infections, and large bony defects remain challenges in orthopedic surgery. Implant surface modifications and coatings are being developed to promote osteointegration, prevent colonization by bacteria, and release bioactive factors. The following mini-review briefly discusses the clinical problem, explains the four "osteos", presents examples of coatings used for different orthopedic indications, and finally raises awareness of the coating and translational requirements.
Ultrasound has been commonly employed for depicting the morphology of the lesions in patients with radial nerve neuropathy, including entrapment, tumor, trauma, and iatrogenic injury. However, few studies have evaluated the efficacy of ultrasound for visualizing radial nerve lesions with coexistent plate fixation of humeral shaft fractures. This study aimed to address this special clinical issue.

We retrospectively examined the efficacy of ultrasound for visualizing radial nerve lesions with coexistent plate fixation of humeral shaft fractures based on intraoperative findings in patients who were treated in our hospital from January 2007 to June 2019.

Forty-six patients were included, and there was a 100% concordance between the ultrasound and intraoperative findings on radial nerve lesions. Ultrasonography revealed four types of lesions radial nerve in continuity in thirty-one patients, neuroma in continuity in four patients, radial nerve stuck under the plate in three patients, and radial nerve transection in eight patients.
