Background/Objectives: Femoral neck fractures are a growing concern due to their increasing incidence in both elderly and younger populations. Preoperative CT scan evaluation is often used for better understanding of fracture patterns of femoral neck fractures that need to be treated using cannulated screws. Methods: The present study retrospectively analyzed 55 patients treated with cannulated screw fixation over seven years. Preoperative CT scans, fracture classification (Garden and Pauwels), and surgical timing were evaluated. Results: All 55 patients were treated with three cannulated screws by nine fellowship-trained surgeons. The average age of the CT-yes group was 54.44 years (SD 15.45), while the average age of the CT-no group was 56.93 (SD 14.95). Differences in age among the two groups were not statistically significant. In 4 patients, the treatment with cannulated screws failed, leading to a subsequent total hip arthroplasty for avascular necrosis (AVN). Three of them belonged to the CT-yes group, while only one belonged to the CT-no group. A statistical analysis showed no significant differences between patients who underwent a CT scan and those who did not have a CT scan and their results (p = 0.282).Results indicate no statistically significant difference in outcomes between patients who underwent a CT scan before the surgical treatment and those who did not, while a well-conducted X-ray assessment is essential and can be sufficient to fully understand and treat most of the fractures. Conclusions: The risks of avascular necrosis and non-union must be considered in the decision-making process regarding the suitable treatment. Early surgery did not significantly improve treatment results, but it is recommended. Fixation with cannulated screws remains a good treatment, especially for some patterns of fractures and younger patients. Given the study’s limitations, including the small sample size and retrospective nature, prospective multicenter studies are warranted to better understand the role of CT scans in optimizing surgical planning and improving patient outcomes.

Background/Objectives: Proximal femur fractures are common in the older population and are related to bone quality. Our work evaluates bone parameters from pelvic anteroposterior (AP) radiographs in patients with trochanteric and sub-capital fractures to determine if there are predictive morphology parameters for each fracture type. Methods: Data from 237 medical records were extracted from patients who arrived at our hospital with trochanteric and sub-capital femoral fractures. Descriptive data and radiological evaluation of the calcar-to-canal ratio (CCR), cortical thickness index (CTI), and Dorr classification were measured by two observers and statistically evaluated. Results: A total of 202 patients were found to be eligible for the study. The mean patient age was 81.41 ± 7.27 years old. The mean age of the trochanteric group was significantly higher than that of the sub-capital group (p = 0.005). There were no statistically significant differences in gender and comorbidities. The CCR showed significance, but the CTI and Dorr classification did not show a significant difference (p = 0.001, p = 0.78, and p = 0.98). A high degree of reliability was shown for all measurements. The ICC for CTI and CCR was p = 0.791 and p = 0.770 (p < 0.001), and Cronbach’s alpha was 0.815 and 0.796, respectively. Logistic regression was found to be significant in predicting 60.4% of correct forecasts with an odds ratio of 0.011 and 95% confidence interval (p = 0.001). For CTI, the correct forecasting rate was 48%, with an odds ratio of 0.615 (p = 0.78). Conclusions: We found that, out of the measured parameters, the CCR stood out as important, showing that higher CCR levels are linked to an increased likelihood of trochanteric fractures.

Background/Objectives: Osteoporotic fractures, particularly subcapital hip fractures (SCF), pose a significant healthcare and economic burden. The routine pathological examination of resected femoral heads in such cases is common practice, aimed at identifying malignancies that may have contributed to bone fragility. This study evaluated the cost-effectiveness and clinical utility of routine femoral head pathology in patients undergoing surgical treatment for SCF. Methods: A retrospective cohort study was conducted at a university-affiliated, tertiary care hospital. Patients undergoing surgical treatment for SCF between 2015 and 2018, with available femoral head pathology reports, were included. Data on demographics, prior or active malignancies, surgical procedures, and pathology results were analyzed. Results: The study included 230 patients with a mean age of 82.4 ± 14.1 years, of whom 57% were female. A total of 72 (31%) patients had a history of malignancy at the time of surgery. Pathological examination identified malignancies in eight patients (3.4%), all of whom had active malignancies at the time of admission. The most common malignancies detected were breast cancer and multiple myeloma (three cases each). None of the findings led to changes in patient management. Conclusions: The routine pathological examination of femoral heads following SCF provided a limited diagnostic yield and did not alter clinical management in this cohort. These findings suggest that routine pathology may not be cost-effective and support the adoption of selective screening approaches based on clinical risk factors such as a history of malignancy or atypical fracture presentations.

Background and Clinical Significance: Femoral neck fracture frequently occurs in the elderly population but may also present in patients diagnosed with primary cancer or bone metastases. A pathological, oligosymptomatic fracture associated with epithelioid haemangioendothelioma (EHE), a rare endothelial cell-derived sarcoma, is uncommon. Case Presentation: A 44-year-old patient underwent biopsy procedures three times (2010, 2012, 2013) for a focal lesion of the left ischium, none confirming its malignant nature. The last biopsy revealed a neoplastic tissue with features of discrete dysplasia. The lesion did not undergo medical follow-up for seven consecutive years. In August 2020, the patient presented with right lower limb pain. A CT scan, PET/CT scan, and biopsy confirmed EHE with spindle/sarcomatous features. In November 2020, chemotherapy (5xADIC) started (PET/CT confirmed a partial response). After its completion in July 2021, bone progression occurred and sirolimus-based therapy was started. After 3 months, a small liver metastasis was visualized on PET/CT, which did not result in the termination of treatment. In December 2021, pamidronate-based antiresorptive therapy was started. Liver metastasis remained stable in follow-up CT scans. Due to pelvic and spinal lesions, the patient was assisted by elbow crutches and underwent radiotherapy, remaining professionally active. The patient did not report any trauma, but in August 2023, a subsequent CT scan revealed a subcapital fracture of the left femoral neck in the fusion phase. Due to pelvic changes and the stable nature of the fracture, surgical treatment was abandoned. Conclusions: An oligosymptomatic femoral neck fracture, not requiring medical intervention is considered a rare complication of bone cancer. Full article

We report two rare cases of femoral neck fracture resulting from osteonecrosis of the femoral head (ONFH) that was undiagnosed at the patients’ initial visits. The patient in the first case had sequential bilateral displaced femoral neck fractures. Because no osteonecrosis of the femoral head was visible on X-ray film and the data of liver function tests were normal, ONFH was not diagnosed. In addition, because the patient was a 55-year-old man with normal everyday functioning, closed reduction with cannulated screws was performed at both visits. Nine months later, he came to our outpatient department with bilateral hip pain; X-rays revealed nonunion and implant failure at both hips. The patient subsequently underwent bilateral total hip arthroplasty (THA) and had a satisfactory outcome at his 4-year follow-up. The patient in the second case had a left displaced femoral neck fracture after trivial trauma two months prior. ONFH was not diagnosed upon examination of X-ray findings. The patient was 52 years old with liver cirrhosis and had bipolar hemiarthroplasty performed because of a chronic displaced fracture and poor general condition. After 2 years, she began to have right hip pain. X-rays revealed massive necrosis and sclerosis of the femoral head. Computed tomography scans for ONFH staging revealed impending fracture lines at the subcapital site of the patient’s previous left femoral neck fracture. Right THA was then performed, and the outcome was satisfactory. Full article

Purpose: Bilateral fatigue femoral fractures (BFFF) represent an extremely rare clinical entity. The present study introduces a novel classification, in order to categorize the BFFFs and provide a thorough review of all these, so far in the literature, reported cases. Methods: The BFFF were classified taking into account the anatomical region of the femoral fracture; (fh): femoral head, (sc): sub-capital, (pt): peri-trochanteric, (st): sub-trochanteric, (s): shaft, (d): distal femur and the fracture type (complete or incomplete); type I: bilateral incomplete fractures, type II: unilateral incomplete fracture, and type III: bilateral complete fractures. Type III was further subdivided into type IIIA: bilateral non-displaced fractures, type IIIB: unilateral displaced fracture, and type IIIC: bilateral displaced fractures. Furthermore, a meticulous review of the PubMed and MEDLINE databases was conducted to locate all articles reporting these injuries. Results: A total of 38 patients (86.8% males), with a mean age of 25.3 years, suffering BFFFs were identified from the literature search. The mean time interval from symptoms’ onset to diagnosis was 54 days. According to the proposed classification, 2.6% of the fractures were categorized as type I (h), 36.8% as type I (sc), 2.6% as type I(st/s), 7.9% as type I (s), 2.6% as type I (d), 5.4% as type II (fh), 26.3% as type II (sc), 2.6% as type IIIA (st), 2.6% as type IIIA (d), 5.4% as type IIIB (sc), 2.6% as type IIIB (d) and 2.6% as type IIIC (sc). Surgery was performed in 52.6%, while non-operative treatment was followed in 47.4% of the population. Regarding the fracture type, 75% of type I fractures were conservatively treated, while 91.7% and 66.6% of type II and III fractures were surgically treated. For patients treated conservatively, the mean time from diagnosis to return to previous status was 260 days, while for patients treated surgically, 343 days. Conclusions: BFFFs, although rare, may pose a diagnostic and therapeutic challenge. The present classification offers valuable information and may act as a guide for the management of these patients.

Bone pathologies such as osteoporosis (OTP) and osteoarthritis (OA) are rising in incidence with the worldwide rise in life expectancy. The diagnosis is usually obtained using imaging techniques such as densitometry, but with both being multifactorial diseases, several molecular mechanisms remain to be understood. Metabolomics offers the potential to detect global changes which can lead to the identification of biomarkers and a better insight in the progress of the diseases. Our aim was to compare the metabolic profiles of a cohort of 100 postmenopausal women, including subcapital hip fragility fracture patients, women with severe OA of the hip that required the implantation of a hip prosthesis and controls, to find altered metabolites and networks. Nuclear magnetic resonance (NMR) spectroscopy was used to obtain the metabolomic profiles of peripheral blood derived serum, and statistical analysis was performed using MATLAB V.6.5. 30 of the 73 metabolites analysed showed statistically significant differences in a 3-way ANOVA, and 11 of them were present in the comparison between OA and controls after adjustment by covariates, including amino acids, energy metabolism metabolites and phospholipid precursors. PLS-DA analysis shows a good discrimination between controls and fracture subjects with OA patients, and ROC curve analysis demonstrates that control and fracture subjects were accurately discriminated using the metabolome, but not OA. These results point to OA as an intermediate metabolic state between controls and fracture, and suggest that some metabolic shifts that happen after a fracture are also present at weaker intensity in the OA process.
