Abstract
OBJECTIVE Metastatic tumours of bone must be considered in all patients with unexplained bone pain and particularly in patients who present with a known cancer, localised pain at multiple sites, and radiographic findings suggestive of metastasis. The purpose of this report was to present a case of a pathological fracture of the mandible as a consequence of metastatic pulmonary adenocarcinoma. MATERIALS AND METHODS In July 2018 a 68-year-old male patient was hospitalised because of pulmonary adenocarcinoma and attended our department for an oral maxillo-facial evaluation. He complained of pain and swelling in the right temporomandibular region resulting in a reported functional limitation. An Orthopantomogram (OPG) demonstrated a right intracapsular condylar compound fracture associated with an osteolytic lesion at the condyle base with jagged margins. Subsequently, a CT scan with contrast of the maxillo-facial complex and a fine-needle aspiration of the lesion was performed. RESULTS CT images showed the presence of a right mandibular condyle fracture associated with a large osteolytic lesion which confirmed the pathological nature of the fracture. Fine-needle aspiration of the lesion confirmed its metastatic nature. It was not possible to proceed with a mandibular resection due to the critical clinical condition of the patient who died in September 2018. CONCLUSION Lung cancer frequently produces lytic-type metastasis, sometimes even in the jaw. In patients with an established diagnosis of lung cancer, any radiolucent lesion of the jaw or an unexplained painful symptomatology to the oro-maxillo facial complex should be placed in differential diagnosis with metastasis of the primary tumour.

Abstract
Tumour-induced osteomalacia is caused by tumorous production of fibroblast growth factor 23 (FGF23) leading to urinary phosphate wasting, hypophosphataemia and decreased vitamin D activation. The resulting osteomalacia presents with muscle weakness and bone pain but progresses to multiple pathological fractures. Patients often remain undiagnosed for years with severe physical, psychological and economic ramifications. A young woman presented with multiple spontaneous fractures including bilateral femoral fractures. Laboratory tests revealed severe hypophosphataemia, elevated bone turnover markers and low to normal calcium and 25-hydroxy-vitamin D levels. Treatment with phosphate, alfalcalcidol, calcium and magnesium was initiated. 68Gallium-DOTATOC positron emission tomography imaging revealed a mass in the right foot and venous sampling of FGF23 from all extremities confirmed this tumour as the culprit. Biopsy and histology were consistent with a phosphaturic mesenchymal tumour, which was surgically resected. Phosphate levels quickly normalised postoperatively but a long convalescence with hungry bone syndrome, fracture healing and physical therapy followed.

Abstract
A man in his 30s came to our clinic with a year-long history of progressive pain and swelling in his knee. Diagnostic imaging revealed a displaced patellar fracture with an osteolytic, septated lesion and thinned expanded cortex in both fracture fragments. A core needle biopsy confirmed the diagnosis of giant cell tumour. Treatment involved wide excision of the tumour and the use of polypropylene mesh and a peroneal longus tendon autograft to reconstruct the extensor mechanism of the knee joint. One year postoperatively, the patient experienced no pain, demonstrated full range of motion and showed no signs of functional impairment or local tumour recurrence. This case highlights that reconstruction of the extensor mechanism of the knee after tumour excision with synthetic mesh is an affordable, user-friendly and widely accessible method. It can address large defects effectively while minimising the risks of disease transmission and graft lengthening, resulting in satisfactory outcomes.

Abstract
Spinal involvement in primary amyloidosis is an exceedingly rare condition, presenting with typical pathological fracture symptoms that are often indistinguishable from other pathologies such as bone metastasis, metabolic disorders and infections. Histopathological studies for tissue diagnosis are the cornerstone of a definitive diagnosis, leading to successful treatment. Early diagnosis and intervention play a pivotal role in the care of patients with amyloidosis. Here, we present a unique case of a pathological fracture in the L4 vertebra following minor trauma. This fracture manifested with pain, instability and limitations in daily activities in a patient who had already been diagnosed with systemic amyloidosis and was undergoing chemotherapy. This case represents a distinct instance of vertebral involvement in amyloidosis and was managed with both chemotherapy and surgical intervention to address the spinal pathology, resulting in favourable outcomes.

Abstract
OBJECTIVE Spine metastases are commonly treated with radiotherapy for local tumor control; pathologic fracture is a potential complication of spinal radiotherapy. Both Hounsfield units (HUs) on CT and vertebral bone quality (VBQ) on MRI have been argued to predict stability as measured by odds of pathologic fracture, although it is unclear if there is a difference in the predictive power between the two methodologies. The objective of the present study was to examine whether one methodology is a better predictor of pathologic fracture following radiotherapy for mobile spine metastases. METHODS Patients who underwent radiotherapy (conventional external-beam radiation therapy, stereotactic body radiation therapy, or intensity-modulated radiation therapy) for mobile spine (C1-L5) metastases at a tertiary care center were retrospectively identified. Details regarding underlying pathology, patient demographics, and tumor morphology were collected. Vertebral involvement was assessed using the Weinstein-Boriani-Biagini (WBB) system. Bone quality of the non-tumor-involved bone was assessed on both pretreatment CT and MRI. Univariable analyses were conducted to identify independent predictors of fracture, and Kaplan-Meier analyses were used to identify significant predictors of time to pathologic fracture. Stepwise Cox regression analysis was used to determine independent predictors of time to fracture. RESULTS One hundred patients were included (mean age 62.7 ± 11.9 years; 61% male), of whom 35 experienced postradiotherapy pathologic fractures. The most common histologies were lung (22%), prostate (21%), breast (14%), and renal cell (13%). On univariable analysis, the mean HUs of the vertebrae adjacent to the fractured vertebra were significantly lower among those experiencing fracture; VBQ was not significantly associated with fracture odds. Survival analysis showed that average HUs ≤ 132, nonprostate pathology, involvement of ≥ 3 vertebral body segments on the WBB system, Spine Instability Neoplastic Score (SINS) ≥ 7, and the presence of axial pain all predicted increased odds of fracture (all p < 0.001). Cox regression found that HUs ≤ 132 (OR 2.533, 95% CI 1.257-5.103; p = 0.009), ≥ 3 WBB vertebral body segments involved (OR 2.376, 95% CI 1.132-4.987; p = 0.022), and axial pain (OR 2.036, 95% CI 0.916-4.526; p = 0.081) predicted increased fracture odds, while prostate pathology predicted decreased odds (OR 0.076, 95% CI 0.009-0.613; p = 0.016). Sensitivity analysis suggested that an HU threshold of ≤ 132 and a SINS of ≥ 7 identified patients at increased risk of fracture. CONCLUSIONS The present results suggest that bone density surrogates as measured on CT, but not MRI, can be used to predict the risk of pathologic fracture following radiotherapy for mobile spine metastases. More extensive vertebral body involvement and the presence of mechanical axial pain additionally predict increased fracture odds.

Abstract
Bone disease is a common complication following liver transplantation, often overlooked in clinical practice. Clinical diagnosis of post-liver transplantation bone disease is challenging, and there have been few case report in the literature. This case report presents a patient who underwent two liver transplant surgeries, exhibited good daily activity, and did not display typical clinical symptoms such as fatigue, bone pain, or spinal deformities associated with prolonged sitting or standing. However, within the fifth year after the second liver transplant, the patient experienced two consecutive fractures. In March 2023, the patient underwent the first bone density test, which revealed osteoporosis. This case highlights the fact that severe fractures after liver transplantation may not necessarily be accompanied by typical symptoms of bone disease. Without timely examination and early prevention, serious consequences may arise. Therefore, this condition requires attention, proactive prevention, early detection, and timely treatment. Additionally, a retrospective analysis of the patient's previous laboratory data revealed persistent abnormalities in serum markers such as hypocalcemia and elevated alkaline phosphatase levels after liver transplantation, emphasizing the importance of monitoring these serum markers.

Abstract
BACKGROUND Improvement in survival in patients with advanced cancer is accompanied by an increased probability of bone metastasis and related pathologic fractures (especially in the proximal femur). The few systems proposed and used to diagnose impending fractures owing to metastasis and to ultimately prevent future fractures have practical limitations; thus, novel screening tools are essential. A CT scan of the abdomen and pelvis is a standard modality for staging and follow-up in patients with cancer, and radiologic assessments of the proximal femur are possible with CT-based digitally reconstructed radiographs. Deep-learning models, such as convolutional neural networks (CNNs), may be able to predict pathologic fractures from digitally reconstructed radiographs, but to our knowledge, they have not been tested for this application. QUESTIONS/PURPOSES (1) How accurate is a CNN model for predicting a pathologic fracture in a proximal femur with metastasis using digitally reconstructed radiographs of the abdomen and pelvis CT images in patients with advanced cancer? (2) Do CNN models perform better than clinicians with varying backgrounds and experience levels in predicting a pathologic fracture on abdomen and pelvis CT images without any knowledge of the patients' histories, except for metastasis in the proximal femur? METHODS A total of 392 patients received radiation treatment of the proximal femur at three hospitals from January 2011 to December 2021. The patients had 2945 CT scans of the abdomen and pelvis for systemic evaluation and follow-up in relation to their primary cancer. In 33% of the CT scans (974), it was impossible to identify whether a pathologic fracture developed within 3 months after each CT image was acquired, and these were excluded. Finally, 1971 cases with a mean age of 59 ± 12 years were included in this study. Pathologic fractures developed within 3 months after CT in 3% (60 of 1971) of cases. A total of 47% (936 of 1971) were women. Sixty cases had an established pathologic fracture within 3 months after each CT scan, and another group of 1911 cases had no established pathologic fracture within 3 months after CT scan. The mean age of the cases in the former and latter groups was 64 ± 11 years and 59 ± 12 years, respectively, and 32% (19 of 60) and 53% (1016 of 1911) of cases, respectively, were female. Digitally reconstructed radiographs were generated with perspective projections of three-dimensional CT volumes onto two-dimensional planes. Then, 1557 images from one hospital were used for a training set. To verify that the deep-learning models could consistently operate even in hospitals with a different medical environment, 414 images from other hospitals were used for external validation. The number of images in the groups with and without a pathologic fracture within 3 months after each CT scan increased from 1911 to 22,932 and from 60 to 720, respectively, using data augmentation methods that are known to be an effective way to boost the performance of deep-learning models. Three CNNs (VGG16, ResNet50, and DenseNet121) were fine-tuned using digitally reconstructed radiographs. For performance measures, the area under the receiver operating characteristic curve, accuracy, sensitivity, specificity, precision, and F1 score were determined. The area under the receiver operating characteristic curve was used to evaluate three CNN models mainly, and the optimal accuracy, sensitivity, and specificity were calculated using the Youden J statistic. Accuracy refers to the proportion of fractures in the groups with and without a pathologic fracture within 3 months after each CT scan that were accurately predicted by the CNN model. Sensitivity and specificity represent the proportion of accurately predicted fractures among those with and without a pathologic fracture within 3 months after each CT scan, respectively. Precision is a measure of how few false-positives the model produces. The F1 score is a harmonic mean of sensitivity and precision, which have a tradeoff relationship. Gradient-weighted class activation mapping images were created to check whether the CNN model correctly focused on potential pathologic fracture regions. The CNN model with the best performance was compared with the performance of clinicians. RESULTS DenseNet121 showed the best performance in identifying pathologic fractures; the area under the receiver operating characteristic curve for DenseNet121 was larger than those for VGG16 (0.77 ± 0.07 [95% CI 0.75 to 0.79] versus 0.71 ± 0.08 [95% CI 0.69 to 0.73]; p = 0.001) and ResNet50 (0.77 ± 0.07 [95% CI 0.75 to 0.79] versus 0.72 ± 0.09 [95% CI 0.69 to 0.74]; p = 0.001). Specifically, DenseNet121 scored the highest in sensitivity (0.22 ± 0.07 [95% CI 0.20 to 0.24]), precision (0.72 ± 0.19 [95% CI 0.67 to 0.77]), and F1 score (0.34 ± 0.10 [95% CI 0.31 to 0.37]), and it focused accurately on the region with the expected pathologic fracture. Further, DenseNet121 was less likely than clinicians to mispredict cases in which there was no pathologic fracture than cases in which there was a fracture; the performance of DenseNet121 was better than clinician performance in terms of specificity (0.98 ± 0.01 [95% CI 0.98 to 0.99] versus 0.86 ± 0.09 [95% CI 0.81 to 0.91]; p = 0.01), precision (0.72 ± 0.19 [95% CI 0.67 to 0.77] versus 0.11 ± 0.10 [95% CI 0.05 to 0.17]; p = 0.0001), and F1 score (0.34 ± 0.10 [95% CI 0.31 to 0.37] versus 0.17 ± 0.15 [95% CI 0.08 to 0.26]; p = 0.0001). CONCLUSION CNN models may be able to accurately predict impending pathologic fractures from digitally reconstructed radiographs of the abdomen and pelvis CT images that clinicians may not anticipate; this can assist medical, radiation, and orthopaedic oncologists clinically. To achieve better performance, ensemble-learning models using knowledge of the patients' histories should be developed and validated. The code for our model is publicly available online at https://github.com/taehoonko/CNN_path_fx_prediction . LEVEL OF EVIDENCE Level III, diagnostic study.

Abstract
BACKGROUND Bisphosphonates inhibit bone resorption in patients with postmenopausal osteoporosis and reduce osteoporotic fracture incidence. Medication-related osteonecrosis of the jaws (MRONJ) and atypical femoral fractures (AFF) are both rare but serious adverse effects of anti-resorptive drugs (ARD) such as bisphosphonates. The most advanced form of MRONJ is termed stage 3 and can lead to severe local sequelae like pathologic mandibular fractures (PMF). This study reports a case of MRONJ-related PMF and AFF with osteomyelitis secondary to bisphosphonate treatment for osteoporosis. CASE REPORT A 63-year-old white woman was diagnosed with PMF related to MRONJ stage 3 during treatment of an AFF with osteomyelitis. She had been treated for postmenopausal osteoporosis with 70 mg of alendronate weekly for 2 years. The PMF was treated by stable internal fixation combined with debridement and sequestrectomy, but further debridement was required and 2 mandibular implants were then removed. Postoperative recovery was uneventful and the mandibular infection was controlled after the second surgery. Three weeks later, she was discharged from the hospital, instructed to discontinue the use of alendronate, and referred for 30 sessions of hyperbaric oxygen therapy. At the 3-year follow-up, the PMF was completely healed without signs of mandibular infection or bone exposure. CONCLUSIONS This report raises awareness of both MRONJ and AFF as possible adverse effects of short-term bisphosphonate therapy for postmenopausal osteoporosis, and highlights the importance of dental and orthopedic follow-ups. It is crucial to emphasize the need for early diagnosis and treatment to prevent MRONJ progression to PMF.

Abstract
Osteoclastomas or brown tumours are named as such due to increased vascularity, subsequent haemorrhage and haemosiderin deposition giving the lesion a reddish brown appearance under gross microscopic examination. It is due to an increase in parathyroid hormone activity from several causes, such as parathyroid adenomas, renal impairment and low vitamin D levels. The lesions increase the tendency of the bone to fracture. The challenging aspect of the diagnosis is that a histological diagnosis without immunohistochemistry is impossible to make. This is because, without special staining, brown tumours cannot be differentiated from giant cell tumours, which are also classed as benign but can be locally destructive and has potential for malignant transformation. Once tissue diagnosis is confirmed as a brown tumour, then aggressive forms of treatment are not needed, and they generally resolve once the underlying cause is treated. We describe a woman in her 80s who presented to the local Orthopaedic service with a pathological ankle fracture due to a brown tumour.

Abstract
BACKGROUND Pathologic fracture of the long bones is a common complication of bone metastases. Intramedullary nail stabilization can be used prophylactically (for impending fractures) or therapeutically (for completed fractures) to preserve mobility and quality of life. However, local disease progression may occur after such treatment, and there is concern that surgical instrumentation and the intramedullary nail itself may seed tumor cells along the intramedullary tract, ultimately leading to loss of structural integrity of the construct. Identifying factors associated with local disease progression after intramedullary nail stabilization would help surgeons predict which patients may benefit from alternative surgical strategies. QUESTIONS/PURPOSES (1) Among patients who underwent intramedullary nail stabilization for impending or completed pathologic fractures of the long bones, what is the risk of local progression, including progression of the existing lesion and development of a new lesion around the nail? (2) Among patients who experience local progression, what proportion undergo reoperation? (3) What patient characteristics and treatment factors are associated with postoperative local progression? (4) What is the difference in survival rates between patients who experienced local progression and those with stable local disease? METHODS Between January 2013 and December 2019, 177 patients at our institution were treated with an intramedullary nail for an impending or completed pathologic fracture. We excluded patients who did not have a pathologic diagnosis of metastasis before fixation, who were younger than 18 years of age, who presented with a primary soft tissue mass that eroded into bone, and who experienced nonunion from radiation osteitis or an avulsion fracture rather than from metastasis. Overall, 122 patients met the criteria for our study. Three fellowship-trained orthopaedic oncology surgeons involved in the care of these patients treated an impending or pathologic fracture with an intramedullary nail when a long bone lesion either fractured or was deemed to be of at least 35% risk of fracture within 3 months, and in patients with an anticipated duration of overall survival of at least 6 weeks (fractured) or 3 months (impending) to yield palliative benefit during their lifetime. The most common primary malignancy was multiple myeloma (25% [31 of 122]), followed by lung carcinoma (16% [20 of 122]), breast carcinoma (15% [18 of 122]), and renal cell carcinoma (12% [15 of 122]). The most commonly involved bone was the femur (68% [83 of 122]), followed by the humerus (27% [33 of 122]) and the tibia (5% [6 of 122]). A competing risk analysis was used to determine the risk of progression in our patients at 1 month, 3 months, 6 months, and 12 months after surgery. A proportion of patients who ultimately underwent reoperation due to progression was calculated. A univariate analysis was performed to determine whether lesion progression was associated with various factors, including the age and sex of the patient, use of adjuvant therapies (radiation therapy at the site of the lesion, systemic therapy, and antiresorptive therapy), histologic tumor type, location of the lesion, and fracture type (impending or complete). Patient survival was assessed with a Kaplan-Meier curve. A p value < 0.05 was considered significant. RESULTS The cumulative incidence of local tumor progression (with death as a competing risk) at 1 month, 3 months, 6 months, and 12 months after surgery was 1.9% (95% confidence interval 0.3% to 6.1%), 2.9% (95% CI 0.8% to 7.5%), 3.9% (95% CI 1.3% to 8.9%), and 4.9% (95% CI 1.8% to 10.3%), respectively. Of 122 patients, 6% (7) had disease progression around the intramedullary nail and 0.8% (1) had new lesions at the end of the intramedullary nail. Two percent (3 of 122) of patients ultimately underwent reoperation because of local progression. The only factors associated with progression were a primary tumor of renal cell carcinoma (odds ratio 5.1 [95% CI 0.69 to 29]; p = 0.03) and patient age (difference in mean age 7.7 years [95% CI 1.2 to 14]; p = 0.02). We found no associations between local disease progression and the presence of visceral metastases, other skeletal metastases, radiation therapy, systemic therapy, use of bisphosphonate or receptor activator of nuclear factor kappa-B ligand inhibitor, type of fracture, or the direction of nail insertion. There was no difference in survivorship curves between those with disease progression and those with stable local disease (= 0.36; p = 0.54). CONCLUSION Our analysis suggests that for this population of patients with metastatic bone disease who have a fracture or impeding fracture and an anticipated survival of at least 6 weeks (completed fracture) or 3 months (impending fracture), the risk of experiencing local progression of tumor growth and reoperations after intramedullary nail stabilization seems to be low. Lesion progression was not associated with the duration of survival, although this conclusion is limited by the small number of patients in the current study and the competing risks of survival and local progression. Based on our data, patients who present with renal cell carcinoma should be cautioned against undergoing intramedullary nailing because of the risk of postoperative lesion progression.

Abstract
PURPOSE OF REVIEW We re-evaluated clinical applications of image-to-FE models to understand if clinical advantages are already evident, which proposals are promising, and which questions are still open. RECENT FINDINGS CT-to-FE is useful in longitudinal treatment evaluation and groups discrimination. In metastatic lesions, CT-to-FE strength alone accurately predicts impending femoral fractures. In osteoporosis, strength from CT-to-FE or DXA-to-FE predicts incident fractures similarly to DXA-aBMD. Coupling loads and strength (possibly in dynamic models) may improve prediction. One promising MRI-to-FE workflow may now be tested on clinical data. Evidence of artificial intelligence usefulness is appearing. CT-to-FE is already clinical in opportunistic CT screening for osteoporosis, and risk of metastasis-related impending fractures. Short-term keys to improve image-to-FE in osteoporosis may be coupling FE with fall risk estimates, pool FE results with other parameters through robust artificial intelligence approaches, and increase reproducibility and cross-validation of models. Modeling bone modifications over time and bone fracture mechanics are still open issues.

Abstract
PURPOSE The aims of this study were to evaluate the degree of cortical thinning and the tumor area in simple radiographs in patients with enchondroma of the hand combined with pathologic fracture and to determine the surgical outcome of simultaneous tumor curettage and internal fixation of fracture. METHODS We enrolled 23 bone lesions of 21 patients diagnosed with enchondroma of the hand. Of them, 9 bone lesions of 8 patients had pathologic fracture. We evaluated the degree of cortical thinning and tumor area in simple radiographs and compared them between patients with and without pathologic fracture. For patients with pathologic fracture, we performed curettage of the tumor through the fracture site and fixed the fracture using K-wires. We then evaluated the clinical outcome of these patients using the visual analog scale to measure pain intensity and Takigawa's criteria 1 year after surgery. RESULTS There was a significant difference in the degree of cortical thinning between the 2 groups (P < 0.001); however, there was no significant difference in the percentage of tumor area (P = 0.259). The average time from surgery to bony union was 8.5 weeks in patients with pathologic fracture. The patients reported that they could return to their previous activities of daily living within 12 weeks of surgery. The average visual analog scale score was 0.6 at 1 year after surgery, and 6 patients were graded as excellent and 2 as good according to Takigawa's criteria. CONCLUSIONS Cortical thinning seems to be related to pathologic fracture. Our scoring system for cortical thinning may be helpful in evaluating the risk for pathologic fracture. Early 1-stage surgical treatment for pathologic hand fracture with enchondroma is a very useful method with satisfactory outcomes that could shorten the treatment period.

Abstract
BACKGROUND Up to 70% of multiple myeloma (MM) patients develop vertebral metastasis and subsequent pathological vertebral fractures (PVF). With contemporary systemic therapies, life expectancy of MM patients has improved drastically, and the need to manage pain and associated disability from PVF is increasingly a high priority. The aim of this review is to provide an updated comprehensive synthesis of evidence in the use of vertebral augmentation, including percutaneous vertebroplasty (PV) and balloon kyphoplasty (BKP), to treat MM-related PVF. METHODS A comprehensive multi-database search in accordance with PRISMA guidelines was performed up to 10 February 2021. Relevant English language articles were selected and critically reviewed. FINDINGS A total of 23 clinical studies have been included in the review. PV and BKP showed significant pain and functional improvements in terms of analgesia requirements, Cervical Spine Function Score, Eastern Cooperative Oncology Group scale, EQ-5D score, Karnofsky score, Neck Pain Disability Index, Oswestry Disability Index, Short form-36 (SF-36) questionnaire and VAS pain scale. Both procedures also reported promising radiographic outcomes in terms of vertebral height improvement, maintenance and restoration, as well as kyphotic deformity correction. Asymptomatic cement leakage was commonly reported. There was no significant difference between the two procedures. CONCLUSION PV and BKP are safe and effective procedure that offers pain relief, reduction in pain associated disability and reduction of fracture incidence. Its minimally invasive approach is associated with minimal morbidity risk, making it a viable option in frail patients. LEVEL OF EVIDENCE IV Narrative review.

Abstract
Simple bone cysts (SBCs) occur most frequently in the proximal aspect of the humerus and femur in growing age and are associated with intercurrent pathological fractures in up to 87%. Therapeutic management of SBCs remains controversial. The aim of this study was to examine the outcome of conservative and various surgical treatment modalities considering the specific anatomic location and integrity of the SBC.In this retrospective study, we analyzed 68 cases of SBCs who underwent a conservative or surgical treatment between 2009 and 2020 with a mean follow-up of 30.1 months. The epidemiological characteristics, complications, clinical, and radiographic outcome after conservative or surgical treatment were assessed.The study includes 50 male (73.5%) and 18 female (26.5%) patients with a mean age of 9.1 years. The most common locations were the proximal humerus (69.2%, n = 47) and femur (16.2%, n = 11). In 43 cases (63.2%; upper limb n = 40, lower limb n = 3) a pathological fracture occurred. Fifty patients (73.5%; upper limb n = 40, lower limb n = 10) underwent a conservative treatment. In 11 cases (16.2.1%; upper limb n = 4, lower limb n = 7) an intralesional curettage and defect reconstruction with bone substitute without stabilization were performed. Five patients (7.3%; upper limb n = 4, lower limb n = 1) received an osteosynthesis, in two cases (2.9%; upper limb 1; lower limb 1) combined with an intralesional curettage and defect reconstruction with bone substitute. All 32 pathological fractures treated conservatively (upper limb n = 31, lower limb n = 1) healed within 6 weeks; 17/43 patients (39.5%) suffered at least one second fracture. After intralesional curettage and defect reconstruction with bone substitute local recurrence was observed in 5/13 cases (38.5%). Spontaneous consolidation, at least partially, was observed in three cases (4.4%) following conservative treatment after fracture. No relevant secondary angular or torsional deformity was observed after treatment.The majority of SBCs can be treated conservatively, especially in the upper extremity. However, if a fracture is completely dislocated, joint affecting, unstable or open, surgical treatment is necessary. Load-dependent pain or the inability to mobilize timely after fracture can necessitate surgical treatment in SBCs affecting the lower extremity. Spontaneous resolution, especially after fracture, can be seen in rare cases.

Abstract
OBJECTIVE To determine the incidence and diagnostic relevance of pathological fracture in patients with conventional central chondrosarcoma (CC-CS). MATERIALS AND METHODS Retrospective review of patients with CC-CS diagnosed between January 2007 and December 2019. Data collected included age, sex, skeletal location and the presence of pathological fracture at presentation. Histological tumour grade based on surgical resection or needle biopsy was classified as atypical cartilaginous tumour (ACT)/grade 1 CS (ACT/Gd1 CS), high-grade CS (HG-CS) and dedifferentiated CS (DD-CS). The presence of pathological fracture was correlated with age, skeletal location and tumour grade. RESULTS Three hundred seventeen patients were included (177 males and 140 females with mean age 55.8 years, range 9-91 years). Mean age of patients without pathological fracture was 54.4 years and those with pathological fracture 62.9 years (p = 0.002). The major long bones were involved in 171 cases, the flat bones in 112 cases, the mobile spine in 7 cases and the small bones of the hands and feet in 27 cases. There were 81 ACT/Gd 1 CS, 168 HGCS and 68 DD-CS. Pathological fracture was evident at presentation in 51 (16.1%) cases, the commonest bones involved being the femur (n = 21; 41.2%), humerus (n = 10; 19.6%) and acetabulum (n = 7; 13.7%). Pathological facture occurred in 7 cases of ACT/Gd 1 CS (13.7%), 23 cases of HGCS (45.1%) and 21 cases of DD-CS (41.2%) (p = 0.001). Following multivariate analysis, both older age and histological grade were independently significant factors. CONCLUSIONS Pathological fracture was seen in 16.1% of patients with CC-CS. Pathological fractures in the femur, humerus and acetabulum very likely indicate higher tumour grade.

Abstract
BACKGROUND The aim of this retrospective study is to analyze history and treatment outcomes of pathological fracture (PF) in dedifferentiated chondrosarcoma (DdChS) of the limbs.. METHODS We retrospectively reviewed 175 adult patients with primary DdChS of the limbs.Disease-specific survival (OS) and local recurrence (LR) were analyzed. RESULTS Median age was 66 years (range, 29-91). Most DdChS (121, 69.1%) were localized in the femur. Forty-nine (28.0%) had metastasis at diagnosis; thirty-nine DdChS (22.3%) had a PF.OS rate was lower in patients with metastasis at diagnosis (8.6% Vs 41.0% at 10 years, p < 0.001). A similar OS was observed among patients with localized disease, whether with/without PF (p = 0.638), with/without chemotherapy (p = 0.543) and independently from the type of surgery (resection/amputation) (p = 0.877). Amputation reduces the risk of LR (80.0% vs 63.1% at 5 years, p = 0.039), particularly in the PF group.. CONCLUSION Patients with metastases have a particularly poor prognosis in DdChS, but pathological fracture does not influence prognosis in terms of survival and local control. Initial curative resection is essential in order to reduce the chance of recurrences. Amputation might be an option in patients with localized disease and a PF to reduce the risk of LR..

Abstract
Six days after a normal delivery, a 24-year-old woman with atraumatic lumbosacral pain radiating to the left groin was referred to the orthopaedic surgeon due to worsening pain and impossible load bearing on the left lower limb. Standard pelvic radiographs revealed an unstable displaced left neck of femur (NOF) fracture. A CT scanner and MRI showed diffuse osteopaenia of the left proximal femur and the corresponding acetabulum. A diagnosis of transient osteoporosis of the hip (TOH) complicated by a pathological displaced subcapital NOF fracture was established. The patient underwent total hip arthroplasty without complication and recovered excellent function after rehabilitation. Awareness of the differential diagnosis of TOH in pregnancy, a high index of suspicion and early MRI to make an early diagnosis and to prevent devastating fracture complications are mandatory.

Abstract
RATIONALE Angiosarcoma is a rare malignant tumors. The objective of this study is to report a patient who suffered from a progressive low back pain and left lower extremities radiation pain for about 8 months, After diagnoses, this was identified as an extremely rare case of primary multiple angiosarcoma of vertebra. PATIENT CONCERNS A 54-year-old man with a history of 2-year hypertension and 8-year diabetes, both of which were well controlled by drug management. Lately, he suffered from a progressive low back pain and left lower extremities radiation pain for about 8 months. DIAGNOSES Magnetic resonance imaging of lumbar showed a clear pathological fracture and primary multiple angiosarcoma of all vertebra. Postoperative pathology and High-throughput sequencing confirmed the diagnosis of primary multiple angiosarcoma of vertebra. INTERVENTIONS The patient underwent minimally invasive pedicle screw fixation combined with bone cement augmentation for the purpose of stabilizing the damaged vertebrae. Following operation, he received both radiotherapy and chemotherapy for a period of time. OUTCOMES The operation has achieved positive results in relieving pain and stabilizing the spine. No wound problem or operative complications occurred after operation. The patient reported an obvious remission of low back pain and was only capable to perform restricted physiological activities. A long-term palliative radiotherapy and chemotherapy were performed after operation. Unfortunately, the patient died 18 months later. CONCLUSION This article emphasizes primary multiple angiosarcoma of vertebra. Despite being rare, it should be part of the differential when the patient manifested back pain and radiculopathy. We recommended the minimally invasive pedicle screw fixation for angiosarcoma of vertebra. Osteoplasty by bone cement augmentation was also an ideal choice for surgical treatment. It also advocates the use of specific targeted radiotherapy drugs based on gene analysis of tumors.

Abstract
INTRODUCTION Langerhans cell histiocytosis (LCH) is a rare neoplastic hyperplasia with an unknown etiology. It is clinically rare for patients with solitary rib lesion and pathological fracture; moreover, its diagnosis and treatment are quite difficult. The purpose of this study is to present a case for the pathogenesis, clinical features, imaging, and treatment of this disease. CASE PRESENTATION A 52-year-old female patient complained of left chest pain for one week. CT showed a fracture in the left 5th rib. The rib tumor was then resected and the surrounding muscles and soft tissues were accordingly resected. The patient was diagnosed with pathological rib fracture, and the patient was pathologically diagnosed with LCH. After surgery, no local recurrence or distant metastasis was reported during the two-year follow-up. CONCLUSIONS LCH should be treated by observation, chemotherapy, radiotherapy, or surgery, or using a combination of several methods. Moreover, primary tumor should be considered when rib fracture without trauma and tumor metastasis.

Abstract
PURPOSE To assess the safety and efficacy of multilevel thoracolumbar vertebroplasty in the simultaneous treatment of ≥ 6 painful pathologic compression fractures. MATERIALS AND METHODS Retrospective review was conducted of 50 consecutive patients treated with vertebroplasty for ≥ 6 pathologic compression fractures in a single session for pain palliation at a tertiary single cancer center from 2015 to 2019. Outcomes measured included procedural safety according to Common Terminology Criteria for Adverse Events (CTCAE), change in 4-week postprocedure back pain by numeric rating scale (NRS), comparison of daily opioid medication consumption, and development of skeletal-related events. RESULTS A total of 397 pathologic compression fractures were treated during 50 sessions (mean, 7.9 per patient ± 1.5). Mean procedure duration was 162 minutes ± 35, mean postoperative hospitalization duration was 1.6 days ± 0.9, and mean follow-up duration was 401 days ± 297. Seven complications were recorded, including 1 case of symptomatic polymethyl methacrylate pulmonary embolism. No major complications (CTCAE grade 4/5) were reported. NRS pain score was significantly decreased (5.0 ± 1.8 vs 1.7 ± 1.4; P < .0001), with a mean score decrease of 3.3 points (66%). Opioid agent use decreased significantly (76 mg/24 h ± 42 vs 45 mg/24 h ± 37; P = .0003), with a mean decrease of 30 mg/24 h (39%). Skeletal-related events occurred in 7 patients (14%). CONCLUSIONS Multilevel vertebroplasty for ≥ 6 pathologic compression fractures is safe and provides significant palliative benefit when performed simultaneously.

Abstract
Metastatic bone disease is incurable with an associated increase in skeletal-related events, particularly a 17-50% risk of pathologic fractures. Current surgical and oncological treatments are palliative, do not reduce overall mortality, and therefore optimal management of adults at risk of pathologic fractures presents an unmet medical need. Plain radiography lacks specificity and may result in unnecessary prophylactic fixation. Radionuclide imaging techniques primarily supply information on the metabolic activity of the tumor or the bone itself. Magnetic resonance imaging and computed tomography provide excellent anatomical and structural information but do not quantitatively assess bone matrix. Research has now shifted to developing unbiased data-driven tools that can predict risk of impending fractures and guide individualized treatment decisions. This review discusses the state-of-the-art in clinical and experimental approaches for prediction of pathologic fractures with bone metastases. Alterations in bone matrix quality are associated with an age-related increase in skeletal fragility but the impact of metastases on the intrinsic material properties of bone is unclear. Engineering-based analyses are non-invasive with the capability to evaluate oncological treatments and predict failure due to the progression of metastasis. The combination of these approaches may improve our understanding of the underlying deterioration in mechanical performance.

Abstract
INTRODUCTION Enchondromas arise from cartilaginous cells derived from the physis that persists throughout development. They are difficult to diagnose and are often discovered on radiographs after a trauma. PATIENT CONCERNS We discuss the case of a 32-year-old woman with a pathologic mallet fracture of the distal phalanx that was initially misdiagnosed as common mallet fracture. DIAGNOSIS Magnetic resonance imaging revealed an eccentrically located lesion expanding to the cortex, with a high signal intensity at T2 weighted image, suggesting pathologic fracture. INTERVENTIONS We performed a operation, involving curettage and bone grafting. Complete removal of the lesion was confirmed intraoperatively with the image intensifier, and the cavity was irrigated and subsequently filled with allogenous bone and demineralized bone matrix. OUTCOMES With an uneventful recovery, she gradually return to normal function within 3 months. Her symptoms improved and nearly full range of motion of the finger was seen at 1-year follow-up. CONCLUSION Our case of pathologic mallet fracture was misdiagnosed as a simple fracture, suggesting that the mechanism of fracture and radiological diagnosis should be carefully considered.

Abstract
Skull fractures are rare in newborns and normally caused by maternal abdominal trauma or complicated deliveries. However, in rare cases, these fractures are found in neonates born after an uneventful pregnancy and delivery. We report a case of a primigravida who underwent cesarean delivery due to failure of descent and malpositioning of the fetal head. After birth, a right temporoparietal fracture and congenital muscular torticollis were diagnosed. The newborn's blood tests showed hypocalcemia and relative hypoparathyroidism. Both mother and newborn presented low vitamin D levels. Serial imaging control showed gradual resolution of the lesions, with the newborn being discharged at the 10th day of life with vitamin D supplementation. This is an interesting case because the combination of three conditions - maternal and fetal hypovitaminosis D, congenital torticollis and malposition of the cephalic pole during labor - may have synergistically contributed to a spontaneous intrauterine skull fracture.

Abstract
Sacral insufficiency fracture is a rare complication of the lumbar spinal surgery. It is normally reported as a late complication of the multi-segment spinal fixation in females with osteoporotic bone. We present the case of an elderly gentleman who suffered this complication spontaneously on the second postoperative day. To the best of our knowledge this has never been reported in Pakistan. Sacral alae are directly in line with weight bearingwhile walking and should be kept in mind when mobilizing a postoperative patient whose previous history indicates such risk factors. Once injury is suspected, CT scan is recommended as x-rays may not always reveal the injury. In literature, these fractures have almost always been treated conservatively.1 Conservative management wasnot tolerated well in our case and we proceeded with surgical management using S2 sacral alar iliac screws (S2 AI screws) to extend the previous lumbosacral fusion construct. S2 AI screws are a novel technique used for bone lumbosacral fusion and studies have shown to have lower rate of screw breakage under stress and need for revision surgery with their use.

Abstract
UNLABELLED The incidence of atypical femoral fractures (AFFs) was 2.95% among 6644 hip and femoral fractures. Independent risk factors included the use of bisphosphonates (BPs), osteopenia or osteoporosis, rheumatoid arthritis, increased femoral curvatures, and thicker femoral cortices. Patients with AFFs and BP treatment were more likely to have problematic healing than those with typical femoral fractures (TFFs) and no BP treatment. INTRODUCTION To determine the incidence and risk factors of atypical femoral fractures (AFFs), we performed a multicenter case-control study. We also investigated the effects of bisphosphonates (BPs) on AFF healing. METHODS We retrospectively reviewed the medical records and radiographs of 6644 hip and femoral fractures of patients from eight tertiary referral hospitals. All the radiographs were reviewed to distinguish AFFs from TFFs. Univariate and multivariate logistic regression analyses were performed to identify risk factors, and interaction analyses were used to investigate the effects of BPs on fracture healing. RESULTS The incidence of AFFs among 6644 hip and femoral fractures was 2.95% (90 subtrochanter and 106 femoral shaft fractures). All patients were females with a mean age of 72 years, and 75.5% were exposed to BPs for an average duration of 5.2 years (range, 1-17 years). The use of BPs was significantly associated with AFFs (p < 0.001, odds ratio = 25.65; 95% confidence interval = 10.74-61.28). Other independent risk factors for AFFs included osteopenia or osteoporosis, rheumatoid arthritis, increased anterior and lateral femoral curvatures, and thicker lateral femoral cortex at the shaft level. Interaction analyses showed that patients with AFFs using BPs had a significantly higher risk of problematic fracture healing than those with TFFs and no BP treatment. CONCLUSIONS The incidence of AFFs among 6644 hip and femoral fractures was 2.95%. Osteopenia or osteoporosis, use of BPs, rheumatoid arthritis, increased anterior and lateral femoral curvatures, and thicker lateral femoral cortex were independent risk factors for the development of AFFs. Patients with AFFs and BP treatment were more likely to have problematic fracture healing than those with TFFs and no BP treatment.

Abstract
BACKGROUND Actual and impending pathologic fractures of the femur are commonly treated with intramedullary nails because they provide immediate stabilization with a minimally invasive procedure and enable direct weightbearing. However, complications and revision surgery are prevalent, and despite common use, there is limited evidence identifying those factors that are associated with complications. QUESTIONS/PURPOSES Among patients treated with intramedullary nailing for femoral metastases, we asked the following questions: (1) What is the cumulative incidence of local complications? (2) What is the cumulative incidence of implant breakage and what factors are associated with implant breakage? (3) What is the cumulative incidence of revision surgery and what factors are associated with revision surgery? METHODS Between January 2000 and December 2015, 245 patients in five centers were treated with intramedullary nails for actual and impending pathologic fractures of the femur caused by bone metastases. During that period, the general indications for intramedullary nailing of femoral metastases were impending fractures of the trochanter region and shaft and actual fractures of the trochanter region if sufficient bone stock remained; nails were used for lesions of the femoral shaft if they were large or if multiple lesions were present. Of those treated with intramedullary nails, 51% (117) were actual fractures and 49% (111) were impending fractures. A total of 60% (128) of this group were women; the mean age was 65 years (range, 29-93 years). After radiologic followup (at 4-8 weeks) with the orthopaedic surgeon, because of the palliative nature of these treatments, subsequent in-person followup was performed by the primary care provider on an as-needed basis (that is, as desired by the patient, without any scheduled visits with the orthopaedic surgeon) throughout each patient's remaining lifetime. However, there was close collaboration between the primary care providers and the orthopaedic team such that orthopaedic complications would be reported. A total of 67% (142 of 212) of the patients died before 1 year, and followup ranged from 0.1 to 175 months (mean, 14.4 months). Competing risk models were used to estimate the cumulative incidence of local complications (including persisting pain, tumor progression, and implant breakage), implant breakage separately, and revision surgery (defined as any reoperation involving the implant other than débridement with implant retention for infection). A cause-specific multivariate Cox regression model was used to estimate the association of factors (fracture type/preoperative radiotherapy and fracture type/use of cement) with implant breakage and revision, respectively. RESULTS Local complications occurred in 12% (28 of 228) of the patients and 6-month cumulative incidence was 8% (95% confidence interval [CI], 4.7-11.9). Implant breakage occurred in 8% (18 of 228) of the patients and 6-month cumulative incidence was 4% (95% CI, 1.4-6.5). Independent factors associated with increased risk of implant breakage were an actual (as opposed to impending) fracture (cause-specific hazard ratio [HR_cs], 3.61; 95% CI, 1.23-10.53, p = 0.019) and previous radiotherapy (HR_cs, 2.97; 95% CI, 1.13-7.82, p = 0.027). Revisions occurred in 5% (12 of 228) of the patients and 6-month cumulative incidence was 2.2% (95% CI, 0.3-4.1). The presence of an actual fracture was independently associated with a higher risk of revision (HR_cs, 4.17; 95% CI, 0.08-0.82, p = 0.022), and use of cement was independently associated with a lower risk of revision (HR_cs, 0.25; 95% CI, 1.20-14.53, p = 0.025). CONCLUSIONS The cumulative incidence of local complications, implant breakage, and revisions is low, mostly as a result of the short survival of patients. Based on these results, surgeons should consider use of cement in patients with intramedullary nails with actual fractures and closer followup of patients after actual fractures and preoperative radiotherapy. Future, prospective studies should further analyze the effects of adjuvant therapies and surgery-related factors on the risk of implant breakage and revisions. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
UNLABELLED Risk for subtrochanteric and diaphyseal femoral fractures is considered increased in patients with hypophosphatasia (HPP). Evaluating a large cohort of HPP patients, we could for the first time quantify the prevalcence and identify both morphometric features as well as predisposing factors for this complication of severe HPP. INTRODUCTION Subtrochanteric and diaphyseal femoral fractures have been associated with both, long-term antiresorptive treatment and metabolic bone disorders, specifically Hypophosphatasia (HPP). Building on a cross-sectional evaluation of real-world data, this study reports risk factors, prevalence, treatment outcome and morphometric particularities for such fractures in HPP as compared to Atypical Femoral Fractures (AFF) in long-term antiresorptive treatment. METHODS For 15 out of 150 HPP patients identified with having experienced at least one such fracture, medical records were reviewed in detail, extracting medical history, genotype, lab assessments, bone mineral density (DXA), radiographic data on femoral geometry and clinical aspects of fracture etiology and healing. RESULTS Bilateral fractures were documented in 10 of these 15 patients, yielding a total of 25 fractures for evaluation. Disease-inherent risk factors included autosomal-recessive, childhood onset HPP, apparently low alkaline phosphatase (ALP) ≤ 20 U/l and substantially elevated pyridoxal 5'-phosphate (PLP) > 3 times upper limit of normal as well as high lumbar spine BMD. Fracture morphology met definition criteria for AFF in 88% of cases. Femoral geometry revealed additional risk factors previously described for AFF, including decreased femoral neck-shaft angle and increased femoral offset. Extrinsic risk factors include Hypovitaminosis D (80%) and pre-treatment with bisphosphonates (46,7%) and Proton-Pump Inhibitors (40%). CONCLUSIONS Increased risk for subtrochanteric and diaphyseal femoral fractures in HPP appears to result from both compromised bone metabolism as well as disease-associated bone deformities. In severe HPP, generous screening for such fractures seems advisable. Bisphosphonates and Hypovitaminosis D should be avoided. Healing is compromised and requires mindful consideration of both pharmacological and surgical options.

Abstract
Solitary plasmacytoma is the rarest type of plasma cell neoplasm, and the anaplastic form is even more uncommon. Plasmacytoma most commonly originates in bone and predominantly affects older patients. We describe the case of a 35-year-old woman with solitary osseous anaplastic plasmacytoma that presented initially with a pathological fracture following minor trauma. The patient was immunocompetent and had no predisposing conditions for a plasma cell tumor. Left lower extremity radiographs revealed an oblique fracture of the distal femur, and CT imaging indicated a primary osseous lesion at the fracture site. MRI confirmed the diagnosis of pathological fracture. Initial surgical pathology of the lesion was concerning because it could have been an osteosarcoma. Further immunostaining demonstrated CD138 positivity and kappa light chain restriction, confirming the diagnosis of plasmacytoma. In addition, the presence of marked anaplastic cellular changes confirmed the anaplastic variant. Further workup showed no evidence of multiple myeloma. This case is unusual given the age and gender of the patient. Awareness of the anaplastic variant of plasmacytoma is important to avoid erroneous diagnoses.

Abstract
We present a case report of a three-year-old girl of Pakistani origin with coeliac disease. The first symptom was spontaneous fracture of the fibula. Vitamin D deficiency rickets and iron deficiency anaemia were demonstrated. An intestinal biopsy and elevated antibody levels confirmed the coeliac disease. Rickets is a known but rare presentation of coeliac disease, but this case report illustrates, how coeliac disease in children often presents with non-gastrointestinal symptoms. The importance of investigations for malabsorp-tion, if iron deficiency is not easily corrected with sufficient iron supplements, is underlined as well as the importance of screening for coeliac disease.

Abstract
Hydatid disease in humans is caused by Echinococcus granulosus. It most commonly involves the liver and, to a lesser extent, the lungs and spleen; however, it is known to involve other areas, too. Involvement of bone by hydatid cyst is rare. Here, we describe the case of a 37-year-old woman who presented with pain in the left groin and swelling in the left thigh. The radiological imaging showed a fracture of the femoral neck and cysts in the shaft of the femur. Diagnosis of hydatid cyst was confirmed on the basis of histopathology of biopsy specimens. The patient recovered after surgical excision of the cyst. This case illustrates the various sites and presentations of hydatid cyst disease, and the need to investigate for it if cystic bony lesions are encountered especially in endemic regions, as a delay in diagnosis can lead to long-term morbidity and even death.

Abstract
UNLABELLED The Fracture Improvement with Teriparatide (Fix-IT) study randomized 13 women with an atypical femur fracture to immediate vs delayed teriparatide therapy; all were followed for 12 months. Results suggested a trend for superior healing and lesser bone mineral density declines in the immediate vs delayed group with no differences in adverse events. PURPOSE Little clinical data are available on the use of teriparatide for the treatment of bisphosphonate-associated atypical femur fractures (AFF). The goal of the Fix-IT study was to determine if immediate therapy with teriparatide was superior for fracture healing after an AFF compared to a 6-month delay in teriparatide therapy. METHODS This randomized pilot clinical trial included 13 women with an AFF who were randomized to immediate teriparatide vs a delay of 6 months. All were followed for 12 months on teriparatide. The primary outcomes included individual and composite measures of radiologic bone healing (scored 1 point [no healing] to 4 points [complete healing]) at 6 and 12 months. Secondary outcomes included bone mineral density of the unfractured contralateral hip, spine, 1/3 distal radius, and adverse events. RESULTS We found there was a trend for superior healing with the composite score (12.6 vs 11.2 at 6 months and 15.4 vs 13.2 at 12 months), and lesser bone mineral density declines at the 1/3 distal radius (12-month change - 1.9 vs - 6.1%) in the immediate vs the delayed group. There were no differences in adverse events. There was one implant failure in the delayed group. CONCLUSIONS There is a preliminary signal for greater improvements with immediate teriparatide therapy vs delayed therapy. However, because an AFF is a rare event, and only a small number of patients were included, the results must be interpreted with caution.

Abstract
Complications of atypical femur fractures (AFFs) are common. AFFs often receive the same treatment as other femoral fractures; however, there appears to be a higher rate of adverse outcomes. Nine patients sustained a total of 13 AFFs, had documented bisphosphonate use before fracture, and had surgery between 2006 and 2012. Complications included continued pain, surgical revision, nonunion, malunion, deformity, or heterotopic ossification. The overall complication rate was 33.3%, with four of the 12 surgeries performed at this institution resulting in one nonunion and three minor complications. None of the primary fixations required revision. There was a higher complication rate for AFFs when compared with non-bisphosphonate-related intramedullary nail femur fracture fixations. This cohort demonstrated a lower rate of major complications compared to the literature. Using a reamed, statically locked nail, halting bisphosphonate medication, and allowing early weight bearing is a safe and efficacious method to treat atypical femur fractures.

Abstract
Osteogenesis imperfecta (OI) is typically characterized by low bone mass and increased bone fragility caused by heterozygous mutations in the type I procollagen genes (COL1A1/COL1A2). We report two cases of a 56-year-old woman and her 80-year-old mother who suffered from multiple vertebral and non-vertebral fractures with onset in early childhood. A full osteologic assessment including dual-energy X-ray absorptiometry (DXA), high-resolution peripheral quantitative computed tomography (HR-pQCT), and serum analyses pointed to a high bone mineral density (BMD) in the hip (DXA Z-score + 3.7 and + 3.9) but low to normal bone mass in the spine and preserved bone microstructure in the distal tibia. Serum markers of bone formation and bone resorption were elevated. Using whole exome sequencing, we identified a novel mutation in the COL1A2 gene causing a p. (Asp1120Gly) substitution at the protein level and affecting the type I procollagen C-propeptide cleavage site. In line with previously reported cases, our data independently prove the existence of an unusual phenotype of high bone mass OI caused by a mutation in the procollagen C-propeptide cleavage with a clinically persistent phenotype through adulthood.

Abstract
Vertebral pathological fracture and metastatic epidural spinal cord compression (MESCC) due to metastatic cancer inevitably cause pain, neurological deficit, impaired function, and decreased quality of life and are indications for surgery. In such cases, earlier surgical intervention has the potential to prevent permanent neurological deficit and disability and to maintain function and quality of life. Therefore, the aim of this study was to identify and evaluate risk factors for pathological fracture and MESCC in patients with spinal metastases. Retrospective assessment of clinical and radiological parameters was undertaken in patients with spinal metastases. Seventy-two patients with spinal metastases underwent decompressive and/or stabilization surgery for pathological fracture and/or MESCC or nerve root compression. The following items were assessed for association with pathological fracture or MESCC: tumor size, location, type, and morphology; disease burden; pain; and function. Pain, tumor size within the vertebral body, vertebral endplate and 3-column involvement, primary tumor growth rate, and multiple vertebral metastases were associated with increased risk for pathological fracture. Vertebral posterior element and costovertebral joint involvement by tumor, primary tumor growth rate, and the presence of visceral metastases were associated with MESCC or nerve root compression. These factors should be considered in the decision-making process for surgery for spinal metastases. Patients with osteolytic spinal metastatic lesions causing pain, greater than 25% occupancy of the vertebral body, and involvement of the vertebral endplate or all 3 columns should be considered for prophylactic or therapeutic decompressive and stabilization surgery.

Abstract
Fragility fractures (FF) are common in patients with chronic kidney disease (CKD), and they occur at a younger age and with a higher frequency than in the general population, producing significant morbidity, mortality and healthcare costs. The pathogenic mechanisms underlying FF in CKD patients have not been completely understood. Behind CKD-MBD, the uremic toxicity should play a role in their pathogenesis, by affecting bone quality (uremic osteoporosis). There are very few prospective studies investigating risk factors for fragility fractures in CKD patients, and available algorithms for fracture risk prediction (FRAX and DeFRA) have never considered CKD. The diagnosis of vertebral fractures (FV), under-diagnosed in CKD patients as well as in general population, should be performed by Quantitative Vertebral Morphometry (QVM) both with DXA or Spine (D4-L5) x-Ray. A recent KDIGO review has qualified the measurement of the Bone Mineral Density by DXA as a predictive tool for fracture risk assessment in patients with stage G3a-G5D. Furthermore, the Trabecular Bone Score (TBS, software applied to DXA) allows the bone quality evaluation as well as the fracture risk prediction. Other techniques, such as Quantitative Computerized Tomography (QCT), especially High Resolution-peripheral QCT (HR-pQCT), have been shown to be useful, although expensive. Finally, some bone biomarkers (PTH and BAP) demonstrated to be informative for the definition of fracture risk in patients with CKD-MBD. In conclusion, there are several different tools and approaches that demonstrated to be useful for the identification of CKD patients at high risk of fracture, when these are appropriately performed and interpreted by expertise clinicians.

Abstract
Histomorphometry or quantitative histology is the analysis on histologic sections of bone resorption, formation and structure parameters. It is the only technique allowing a dynamic evaluation of osteoblast activity after labelling with tetracycline. In addition, the use of computed image analyzer allows the possibility to assess bone microarchitecture. Histomorphometric bone biopsy is a reliable and well-tolerated procedure. Bone samples are taken at iliac crest level under local anesthesia and sedation. Samples are put into methyl-metacrilate resin where the sections are prepared for the microscopic analysis of different histomorphometric parameters. Histomorphometry is used to exclude or confirm the diagnosis of osteomalacia and also to evaluate bone damage associated with particular treatments (for example, glucocorticoids, anticonvulsants) or in case of rare bone diseases (osteogenesis imperfecta). Recently, this approach has been repurposed for the evaluation of bone disease during Chronic Kidney Disease, particularly to differentiate high and low bone turnover osteodystrophy. Kidney Disease Improving Global Outcomes (KDIGO) guidelines have pointed out the situations requiring bone biopsy for histomorphometric analysis. New techniques using molecular biology will improve the accuracy and predictive value of this approach.

Abstract
Twenty-five percent of patients with a non-hip non-vertebral fragility fracture have an undiagnosed vertebral fracture detected by vertebral fracture assessment during bone densitometric assessment. The prevalence of an undiagnosed vertebral fracture is higher in older people, and they are more likely to have multiple vertebral fractures. PURPOSE Most vertebral fragility fractures (VFF) have no history of trauma. Vertebral fracture assessment (VFA) during dual energy x-ray absorptiometry (DXA) can be used to detect these VFFs. This study aims to identify the prevalence of undiagnosed VFF in patients presenting with a non-hip non-vertebral fragility fracture. METHODS Patients identified by the fracture liaison service (FLS) of a large UK university hospital presenting with a non-hip non-vertebral fragility fracture were evaluated from 1 January 2012 to 30 September 2015. Local protocol identified those that would proceed for VFA. Data was collected on patient characteristics, fracture details, bone mineral density (BMD) measurements and VFA results. RESULTS Five hundred sixty-seven patients (mean (SD) age, 72 (9.4) years) of mostly women (88.3%) had a VFA performed as part of their DXA assessment. One hundred forty-three patients (25.2%) were identified to have a vertebral fracture, of whom 57.3% of them had one fracture. 49.5% of those with vertebral fractures had BMD measurements diagnostic of osteoporosis. Mean (SD) age was higher in those with vertebral fractures compared to those without; 74.9 (8.3) years vs 70.4 (9.5) years, p < 0.00. Those aged 75 years and over were more likely to have multiple fractures than those younger than 75 years (16.3 vs 4%, p = 0.01). CONCLUSION A quarter of patients presenting with a non-hip non-vertebral fragility fracture have an undiagnosed vertebral fracture. Older people are more likely to have vertebral fractures and more likely to have multiple fractures. VFA during bone densitometric assessment can further aid stratifying future fracture risk.
