Abstract
PURPOSE Immune checkpoint inhibitors (ICIs) have improved the prognosis of patients with cancer, such as melanoma, renal cell carcinoma, head and neck cancer, non-small cell lung cancer (NSCLC), and urothelial carcinoma. The extension of life expectancy has led to an increased incidence of bone metastases (BM) among patients with cancer. BM result in skeletal-related events, including severe pain, pathological fractures, and nerve palsy. Surgery is typically required for the treatment of BM in patients with an impending fracture; however, it may be avoided in those who respond to ICIs. We systematically reviewed studies analyzing BM responses to treatment with ICIs. METHODS This study was conducted in accordance with the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-analyses 2020 statement and registered in the UMIN Clinical Trials Registry (ID: UMIN000053707). Studies reporting response rates based on the Response Evaluation Criteria in Solid Tumors (RECIST) or the MD Anderson Cancer Center (MDA) criteria specific for BM in patients treated with ICIs were included; reports of fewer than five cases and review articles were excluded. Studies involving humans, published in English and Japanese, were searched. The PubMed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched. Ultimately, nine studies were analyzed. The Risk of Bias Assessment tool for Non-randomized Studies was used to assess the quality of studies. RESULTS Based on the MDA criteria, complete response (CR) or partial response (PR) was observed in 44-78% and 62% patients treated with ICIs plus denosumab for NSCLC and melanoma, respectively. According to the RECIST, CR or PR was recorded in 5% and 7-28% of patients treated with ICIs for renal cell carcinoma and urothelial carcinoma, respectively. CONCLUSION Although response rates to ICIs for BM are poor, patients treated with ICI plus denosumab for bone metastases with impending fractures from NSCLC and melanoma are likely to avoid surgery to prevent fractures.

Abstract
In this study, polylactic acid (PLA) microspheres were used as the raw material to construct bulk implants with surface microtopography through hot pressing and heat treatment, and the microtopographical structures were regulated through the sizes of the PLA microspheres. The surface microtopographies of PLA implants were successfully constructed using micron-sized bulges, which showed a wave-like structure. The ridge width of bulges ranged from 1.64 ± 0.16 µm to 82.52 ± 14.38 µm and the valley depth ranged from 0.49 ± 0.07 µm to 37.35 ± 6.78 µm according to the sizes of microspheres. The nanoindentation tests showed that the modulus and hardness of PLA implants were gradually increased with the decrease in microsphere sizes. The surface microtopography resulted in a slight increase in the hydrophobicity of the PLA implants, but no significant differences were observed. Cells cultured on the implant surface with microtopography exhibited varying morphological responses, and significantly increased osteogenic activity was observed relative to a PLA flat film. This study demonstrated that the surface microtopography derived from PLA microspheres could regulate cellular response and activate osteogenic properties of PLA implants.

J Surg Oncol 2023. [PMID: 36966436 DOI: 10.1002/jso.27247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 02/19/2023] [Accepted: 03/07/2023] [Indexed: 03/27/2023]
Abstract
BACKGROUND Bone metastases are frequent in patients with cancer. Electrochemotherapy (ECT) is a minimally invasive treatment based on a high-voltage electric pulse combined with an anticancer drug. Preclinical and clinical studies supported the use of ECT in patients with metastatic bone disease, demonstrating that it does not damage the mineral structure of the bone and its regenerative capacity, and that is feasible and efficient for the treatment of bone metastases. Year 2014 saw the start of a registry of patients with bone metastases treated with ECT, whose data are recorded in a shared database. QUESTIONS/PURPOSES (1) Among patients who underwent ECT and internal fixation for bone metastasis, how many experienced a reduction of pain? (2) How many cases showed a radiological response? (3) How many patients presented local or systemic complication after ECT and fixation? PATIENTS AND METHODS Patients were treated in Bologna at Rizzoli Orthopaedic Institute between March 2014 and February 2022 and recorded in the REINBONE registry (a shared database protected by security passwords): clinical and radiological information, ECT session, adverse events, response, quality of life indicators, and duration of follow-up were registered. We consider only cases treated with ECT and intramedullary nail during the same surgical session. Patients included in the analysis were 32: 15 males and 17 females, mean age 65 ± 13 years (median 66, range 38-88 years), mean time since diagnosis of primary tumor 6.2 ± 7.0 years (median 2.9, range 0-22 years). Nail was indicated in 13 cases for a pathological fracture in, 19 for an impending fracture. Follow-up was available for 29 patients, as 2 patients were lost to follow-up and 1 was unable to return to controls. Mean follow-up time was 7.7 ± 6.5 months (median 5, range 1-24), and 16 patients (50%) had a follow-up longer than 6 months. RESULTS A significant decrease in pain intensity was observed at the mean Visual Numeric Scale after treatment. Bone recovery was observed in 13 patients. The other 16 patients remained without changes, and one presented disease progression. One patient presented a fracture occurrence during the ECT procedure. Among all patients, bone recovery was observed in 13 patients: complete recovery in 1 patient (3%) and partial recovery in 12 patients (41%). The other 16 patients remained without changes, and one presented disease progression. One patient presented a fracture occurrence during the ECT procedure. However, healing was possible with normal fracture callus quality and healing time. No other local or systemic complications were observed. CONCLUSION We found that pain levels decreased after treatment in 23 of the 29 cases for a pain relief rate of 79% at final follow-up. Pain is one of the most important indicators of quality of life in patients that undergo palliative treatments. Even if conventional external body radiotherapy is considered a noninvasive treatment, it presents a dose-dependent toxicity. ECT provides a chemical necrosis preserving osteogenic activity and structural integrity of bone trabeculae; this is a crucial difference with other local treatments and allows bone healing in case of pathological fracture. The risk of local progression in our patient population was small, and 44% experienced bone recovery while 53% of the cases remained unchanged. We observe intraoperative fracture in one case. This technique, in selected patients, improves outcome in bone metastatic patients combing both the efficacy of the ECT in the local control of the disease and the mechanical stability with the bone fixation to synergize their benefits. Moreover, the risk of complication is very low. Although encouraging data, comparative studies are required to quantify the real efficacy of the technique. Level of Evidence Level I, therapeutic study.

Cemented vs uncemented megaprostheses in proximal femur metastases: a multicentric comparative study. BMC Musculoskelet Disord 2022; 22:1068.

Abstract
BACKGROUND Hip megaprostheses are a long known reconstructive method in the treatment of proximal femur metastases. The use of cemented or uncemented stems is still matter of debate. The aim of this study to compare cemented and uncemented megaprostheses on functional outcomes and complications, in order to establish the role of cementation. METHODS We retrospectively analysed 51 metastatic patients with proximal femur metastases treated with endoprosthetic reconstruction by megaprostheses, 25 with cementless stems and 26 with cemented ones with different megaprosthetic implants. The primary endpoint was MSTS score, and the secondary endpoint was to state the incidence of surgical and clinical complications in the two groups. An un-paired T test was used to compare anthropometric, anamnestic data, and MSTS. Chi-square test was performed for evaluation of complication in the two group. Multiple linear regression was used to match the functional outcomes and complications' incidence in the population study. Logistic regression was performed to analyse the odds ratio of different parameters and their role in the incidence of complications. RESULTS The mean follow-up was 50.1 months (+ 12.5). In thirty case right side was involved. No statistical differences were noticed between Group A and B regard the age, gender, active fracture/impending fracture. Comparing the MSTS results within the two groups at last follow-up, the score cemented group was higher than cementless one (17.9 + 7.8 vs 24.2 + 5.3; statistical significance p = 0.001). Regarding surgical complications a logistic regression was performed to analyse the odds ratio of age, cementation and length of resection; cementation confirm and odds ratio of 11 times in the incidence of surgical complications. CONCLUSIONS Cementation seems to be more liable to complications onset, while improves functional score in metastatic patients compared to uncemented megaprostheses. More studies have to be conducted in order to create a protocol and establish criteria to use cemented or uncemented stems in a frail population like metastatic patients.

Abstract
Surgery for bone metastasis has two primary goals-palliative care to relieve pain, instability and paralysis, and tumor resection for curing the disease. Oncologically en bloc resection, followed by a reconstruction of the bone defect is the treatment of choice in single bone metastasis from renal cell carcinoma or thyroid cancer. Bone metastases may occur in the extremities, pelvis, or spine, and different resection and reconstruction methods depend on the regional anatomy. For instance, multiple options are available for reconstruction of the pelvis, especially for the acetabulum, including anatomical reconstruction using custom-made implants or recycled autologous bone grafting when a long-term prognosis is expected. Recently, for the spine, total en bloc spondylectomy is extensively performed despite the initial limitations of surgical invasiveness, such as blood loss. Principally, palliative surgery aims to maintain lasting bony stability with minimal surgical invasiveness. Intramedullary nails and plate fixation are frequently used in the extremities but the postoperative failure rate is relatively high. Therefore, surgeons should consider the use of long intramedullary nails and long-type stems for endoprosthesis reconstruction along with cement fixation to reduce the failure rate. Although short-term complications, such as dislocation, have been observed with endoprosthesis reconstruction, it is stable in the long-term follow-up. Percutaneous bone cement injection into the spine and pelvis is also effective and less invasive.

International Validation of the SORG Machine-learning Algorithm for Predicting the Survival of Patients with Extremity Metastases Undergoing Surgical Treatment. Clin Orthop Relat Res 2022; 480:367-378. [PMID: 34491920 PMCID: PMC8747677 DOI: 10.1097/corr.0000000000001969] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Accepted: 08/17/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND The Skeletal Oncology Research Group machine-learning algorithms (SORG-MLAs) estimate 90-day and 1-year survival in patients with long-bone metastases undergoing surgical treatment and have demonstrated good discriminatory ability on internal validation. However, the performance of a prediction model could potentially vary by race or region, and the SORG-MLA must be externally validated in an Asian cohort. Furthermore, the authors of the original developmental study did not consider the Eastern Cooperative Oncology Group (ECOG) performance status, a survival prognosticator repeatedly validated in other studies, in their algorithms because of missing data. QUESTIONS/PURPOSES (1) Is the SORG-MLA generalizable to Taiwanese patients for predicting 90-day and 1-year mortality? (2) Is the ECOG score an independent factor associated with 90-day and 1-year mortality while controlling for SORG-MLA predictions? METHODS All 356 patients who underwent surgery for long-bone metastases between 2014 and 2019 at one tertiary care center in Taiwan were included. Ninety-eight percent (349 of 356) of patients were of Han Chinese descent. The median (range) patient age was 61 years (25 to 95), 52% (184 of 356) were women, and the median BMI was 23 kg/m2 (13 to 39 kg/m2). The most common primary tumors were lung cancer (33% [116 of 356]) and breast cancer (16% [58 of 356]). Fifty-five percent (195 of 356) of patients presented with a complete pathologic fracture. Intramedullary nailing was the most commonly performed type of surgery (59% [210 of 356]), followed by plate screw fixation (23% [81 of 356]) and endoprosthetic reconstruction (18% [65 of 356]). Six patients were lost to follow-up within 90 days; 30 were lost to follow-up within 1 year. Eighty-five percent (301 of 356) of patients were followed until death or for at least 2 years. Survival was 82% (287 of 350) at 90 days and 49% (159 of 326) at 1 year. The model's performance metrics included discrimination (concordance index [c-index]), calibration (intercept and slope), and Brier score. In general, a c-index of 0.5 indicates random guess and a c-index of 0.8 denotes excellent discrimination. Calibration refers to the agreement between the predicted outcomes and the actual outcomes, with a perfect calibration having an intercept of 0 and a slope of 1. The Brier score of a prediction model must be compared with and ideally should be smaller than the score of the null model. A decision curve analysis was then performed for the 90-day and 1-year prediction models to evaluate their net benefit across a range of different threshold probabilities. A multivariate logistic regression analysis was used to evaluate whether the ECOG score was an independent prognosticator while controlling for the SORG-MLA's predictions. We did not perform retraining/recalibration because we were not trying to update the SORG-MLA algorithm in this study. RESULTS The SORG-MLA had good discriminatory ability at both timepoints, with a c-index of 0.80 (95% confidence interval 0.74 to 0.86) for 90-day survival prediction and a c-index of 0.84 (95% CI 0.80 to 0.89) for 1-year survival prediction. However, the calibration analysis showed that the SORG-MLAs tended to underestimate Taiwanese patients' survival (90-day survival prediction: calibration intercept 0.78 [95% CI 0.46 to 1.10], calibration slope 0.74 [95% CI 0.53 to 0.96]; 1-year survival prediction: calibration intercept 0.75 [95% CI 0.49 to 1.00], calibration slope 1.22 [95% CI 0.95 to 1.49]). The Brier score of the 90-day and 1-year SORG-MLA prediction models was lower than their respective null model (0.12 versus 0.16 for 90-day prediction; 0.16 versus 0.25 for 1-year prediction), indicating good overall performance of SORG-MLAs at these two timepoints. Decision curve analysis showed SORG-MLAs provided net benefits when threshold probabilities ranged from 0.40 to 0.95 for 90-day survival prediction and from 0.15 to 1.0 for 1-year prediction. The ECOG score was an independent factor associated with 90-day mortality (odds ratio 1.94 [95% CI 1.01 to 3.73]) but not 1-year mortality (OR 1.07 [95% CI 0.53 to 2.17]) after controlling for SORG-MLA predictions for 90-day and 1-year survival, respectively. CONCLUSION SORG-MLAs retained good discriminatory ability in Taiwanese patients with long-bone metastases, although their actual survival time was slightly underestimated. More international validation and incremental value studies that address factors such as the ECOG score are warranted to refine the algorithms, which can be freely accessed online at https://sorg-apps.shinyapps.io/extremitymetssurvival/.

Abstract
Objective
To evaluate the better potential and functional results in pain control in the treatment of pathological fractures and prophylactic fixation with an intramedullary nail associated with polymethylmethacrylate, compared with the utilization of an intramedullary nail in long bone tumor lesions.
Methods
From January 2012 to September 2017, 38 patients with 42 pathological lesions (fractures or impending fractures according to the Mirels criteria) were treated surgically. Sixteen patients allocated to the control group underwent a locked intramedullary nail fixation, and 22 patients with pathological lesions were allocated to treatment with an intramedullary nail associated with polymethylmethacrylate. Postoperatively, the patients were submitted to the Musculoskeletal Tumor Society (MSTS) rating scale, radiographic assessment, and to the assessment of events and complications related to the treatment.
Results
The evaluation using the MSTS questionnaire showed better functional results in the group associated with polymethylmethacrylate, in comparison with the control group, which obtained an average score of 16.375 out of a maximum of 30 points (54.6%). The group studied with association with polymethylmethacrylate obtained a mean of 22.36 points (74.5%). The procedure proved to be safe, with similar complication and severity rates, and with no statistical difference in comparison with the standard treatment.
Conclusion
Stabilization of tumor lesions with an internal fixation associated with the polymethylmethacrylate demonstrated early rehabilitation and improved the quality of life, allowing rapid functional recovery. The use of polymethylmethacrylate has advantages such as reduced bleeding, tumor necrosis and higher mechanical stability.

Abstract
The proximal femur is a common location for the development of bony metastatic disease. Metastatic bone disease in this location can cause debilitating pain, pathologic fractures, reduced quality of life, anemia or hypercalcemia. A thorough history, physical examination and preoperative investigations are required to ensure accurate diagnosis and prognosis. The goals of surgical management is to provide pain relief and return to function with a construct that provides stability to allow for immediate weightbearing. Current surgical treatment options include intramedullary nailing, hemiarthroplasty or total hip arthroplasty and endoprosthetic reconstructions. Oligometastatic renal cell carcinoma must be given special consideration as tumor resection and reconstruction has survival benefit. Both tumor and patient characteristics must be taken into account before deciding on the appropriate surgical intervention.

Abstract
The number of patients with bone metastasis increases as medical management and surgery improve the overall survival of patients with cancer. Bone metastasis can cause skeletal complications, including bone pain, pathological fractures, spinal cord or nerve root compression, and hypercalcemia. Before initiation of treatment for bone metastasis, it is important to exclude primary bone malignancy, which would require a completely different therapeutic approach. It is essential to select surgical methods considering the patient’s prognosis, quality of life, postoperative function, and risk of postoperative complications. Therefore, bone metastasis treatment requires a multidisciplinary team approach, including radiologists, oncologists, and orthopedic surgeons. Recently, many novel palliative treatment options have emerged for bone metastases, such as stereotactic body radiation therapy, radiopharmaceuticals, vertebroplasty, minimally invasive spine stabilization with percutaneous pedicle screws, acetabuloplasty, embolization, thermal ablation techniques, electrochemotherapy, and high-intensity focused ultrasound. These techniques are beneficial for patients who may not benefit from surgery or radiotherapy.

Complications after intramedullary nail fixation of pathological versus non-pathological femoral shaft fractures: a retrospective cohort study in 233 patients. Patient Saf Surg 2021; 15:29. [PMID: 34446070 PMCID: PMC8390257 DOI: 10.1186/s13037-021-00304-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Accepted: 07/27/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Postoperative adverse events after intramedullary nailing have been reported in patients with metastatic pathological and non-pathological femoral fractures. Other consequences to be considered are readmission and reoperation. Few studies have compared the risks of postoperative adverse events, reoperation, and readmission after intramedullary nailing of pathological and non-pathological femur fractures. This study was designed to test the hypothesis that patients with pathological femoral fractures had more adverse events, readmission, and reoperation following surgical fixation than non-pathological femoral fractures. METHODS This was a retrospective observational cohort study, conducted at an academic medical center in Thailand. The data from patients with femoral shaft fractures undergoing long intramedullary nailing, from June 1, 2006, to June 30, 2020, were included. Patients who had a pathological fracture from a primary bone tumor, metabolic bone disease, or inadequate/missing information were excluded. Patients with pathological fractures from metastatic bone disease were assigned to be the pathological group whereas those with traumatic fractures were assigned to be the non-pathological group. The primary outcome was the risk of inpatient adverse events as compared between the two groups. The secondary outcome was the risk of consequences after discharge as compared between the two groups. Outcomes were analyzed by using multivariate logistic regression analysis. RESULTS The total number of patients was 48 in the pathological fracture group and 185 in the non-pathological group. There were significantly higher rates of surgical and medical adverse events in patients with pathological fractures compared to patients with non-pathological fractures. After adjusting for potential confounding factors in multivariate regression analysis, patients with pathological fractures had higher odds of both adverse surgical (adjusted OR 2.43, 95 % CI 1.15-5.13) and medical adverse events (adjusted OR 2.81, 95 % CI 1.13-7.03). CONCLUSIONS Patients with metastatic pathological femoral shaft fractures undergoing intramedullary nailing were more likely to experience postoperative adverse events than patients with non-pathological fractures.

Abstract
Metastasis of the distal tibia is quite rare. In this article, we present the case of a 58-year-old woman with distal tibial metastasis located in the posterior malleous caused by breast cancer. She had left ankle pain and nonweightbearing status that had been ongoing for 2 months and showed progression. The patient's Mirels score was 10. Limb salvage surgery was performed by removing the metastatic lesion by posterior ankle incision followed by applying a double plate from the posterior and the medial side of the distal tibia, and the defect was reconstructed with methylmethacrylate. Consequently, good stability was achieved. Radiotherapy consisting of 10 fractions (2000 cGy total) was applied to the distal tibia at postoperative week 3. There were no complications after surgery. No recurrence was observed at the 18-month follow-up of the patient. The Musculoskeletal Tumor Society Score at the 18-month control of the patient was 86%. Use of curettage of the metastatic mass, double-plate application, and defect reconstruction with methylmethacrylate is an effective method for distal tibia metastases located in the posterior malleolus.

A proposed ''A to Z RAM (Radiograph Assessment Method)'' for triage of patients with a suspected bone tumour. Radiography (Lond) 2021; 27:823-830. [PMID: 33487526 DOI: 10.1016/j.radi.2021.01.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Revised: 12/19/2020] [Accepted: 01/01/2021] [Indexed: 11/24/2022]
Abstract
INTRODUCTION We propose a ''A to Z RAM (Radiograph Assessment Method)'' for evaluation of Radiograph of patients with a suspected bone tumour. METHODS In the current study, ten radiological features with letters 'A, B, C, D, E, F and Z' were used and which included the age of the patient, involved part of the bone, characteristics, content, distinctiveness, the exterior of the bone, fracture, and zone of transition. Four independent observers (orthopaedic oncologists and surgical oncologists) evaluated a set of 30 radiographs of bone tumour selected at random from our hospital database based on A to Z RAM. We classified the lesions into two groups according to the traffic signal system; Green (suspected benign lesion) and Red (suspected malignant lesion). RESULTS There were 18 (60%) benign bone lesions and 12 (40%) malignant lesions in the current study. 91.6% of malignant tumours and 88.8% of the benign tumours were identified correctly by the four observers. The inter-observer variability with Fleiss kappa was 0.884 (95% CI 0.7-1.03 p-value < 0.05), suggestive of agreement not by chance. These radiographs were again reassessed by the four observers after 3 months. The interobserver variability by Fleiss kappa was 1.0 (95% CI 0.8-1.1) suggesting complete agreement amongst the observers. Both orthopaedic oncologists had intra-observer kappa as 1.0 each and both surgical oncologists had 0.795 and 0.930 respectively. CONCLUSION The proposed A to Z RAM is an easy to use and reproducible method for reviewing radiographs in the out-patient department along with clinical findings for better management of patients with suspected bone lesions. The A to Z RAM can be a medical triage tool and subdivide bone lesions into two subgroups i.e. suspected benign lesion with a suggestion of further investigations with MRI and biopsy and suspected malignant lesion with a suggestion of MRI or early referral to a tertiary cancer center with expertise in orthopaedic oncology. IMPLICATIONS FOR PRACTICE The A to Z RAM (Radiologic Assessment Method) is a reproducible method for reviewing radiographs in the out-patient department and can be an aid for better management of patients. A to Z RAM is useful as a medical triage system, subdividing patients according to the probable diagnosis into a suspected benign lesion and suspected malignant lesion.

Abstract
INTRODUCTION Long bone metastasis to the tibia is somewhat rare and has only been studied in a few publications with a limited number of cases. This led us to carry out a large multicenter, observational, retrospective study to 1) evaluate the clinical and radiological outcomes of surgical treatment at this location and 2) highlight the specific risks associated with this condition. HYPOTHESIS We hypothesized that the clinical outcomes and survivorship were comparable to those reported in the literature. MATERIAL AND METHODS The case series included 15 men and 10 women with a mean age of 66±11.7 years. The most common primary cancers were kidney (10 patients) and lung (4 patients). Thirteen patients had a concurrent visceral metastasis and sixteen had metastasis in another bone. The tibial metastasis was the initial sign of cancer in seven patients. The surgical procedure was done to prevent an impending fracture in 19 patients and to treat a pathological fracture in 6 patients (initial sign of cancer in 4 patients). Osteolysis occurred in the proximal epiphysis/metaphysis in 12 patients, diaphysis in 9 patients and distal epiphysis/metaphysis in 4 patients. We performed fixation with a lateral cortex plate and cementoplasty in 14 patients, locked intramedullary nailing in 8 patients, cementoplasty only in 2 patients and knee arthroplasty in 1 patient. RESULTS Three surgical site infections, one pulmonary embolism and one cardiac rhythm disturbance occurred. Four patients died before the 3rd month postoperative. At their best clinical status, 2 patients had not resumed walking, 10 could walk short distances with two canes or a walker, 3 had altered gait but could walk without aids and 6 could walk normally. The mean survival was 14±11.7 months (95% CI: 8.1-19.8) for all patients, 4±4 months (95% CI: 3-14) for those with a lung primary and 32±14 months (95% CI: 20-47) for those with a kidney primary. The survival was 15 months (95% CI: 4-29) after preventative treatment and 5 months (95% CI: 4-26) after fracture treatment. CONCLUSION Our clinical outcomes are comparable overall to the three main published articles on this topic. The risk of infection and benefits of preventative fixation were apparent in our cohort. LEVEL OF EVIDENCE IV, retrospective study.

Abstract
INTRODUCTION Peripheral skeletal metastasis (PSM) has a negative impact on quality of life. New treatments for the primary tumor or the osteolysis hold out hope of improved survival. The few published French series were small, and we therefore undertook a multicenter retrospective analysis of PSM surgery between 2005 and December 2016, with the aim of assessing: 1) rate and type of complications, 2) functional results, and 3) overall survival and corresponding risk factors. HYPOTHESIS The French data for clinical results, survival and complications are in agreement with the international literature. MATERIALS AND METHOD The series comprised 391 patients with 434 metastatic locations. There was female predominance: 247 women (63%). Two sites were treated in 46 patients (12%), and three in 5. The main etiologies were breast cancer (151/391: 39%), lung cancer (103/391: 26%) and kidney cancer (52/391: 13%). There was synchronous visceral metastasis in 166 patients (42.5%), other peripheral locations in 137 (35%) and spinal location in 142 (39%). One hundred (27%) had ASA score>3; 61 (16%) had WHO score>3. The reason for surgery was pathologic fracture (n=137: 35%). Locations were femoral (274: 70%), acetabular (58: 15%), humeral (40: 0%), tibial (12: 3%) or other (7: 2%). RESULTS There were surgery site complications in 41 patients (9.4%), including 13 surgery site infections, and general complications in 47 patients (11%), including 11 cases of thromboembolism, 6 of blood loss, 9 pulmonary complications and 6 perioperative deaths. Overall survival, taking all etiologies and sites together, was 10 months (range, 5 days to 9 years; 95% CI, 8-13 months), and significantly better in females (14 versus 6 months; p=0.01), under-65 year-olds (p=0.001), and in preventive surgery versus fractured PSM (p=0.001). Median survival was 22 months (95% CI, 17-28 months) after breast cancer, 3 months (95% CI, 2-5 months) after lung cancer, and 17 months (95% CI, 8-58 months) after kidney cancer. Preoperatively, walking was impossible for 143 patients (38%), versus 23 (6.5%) postoperatively; 229 patients (63.5%) could walk normally or nearly normally after surgery, versus 110 (28%) before. After surgery, 3 patients (6%) were not using their operated upper limb, versus 27 (45%) before; 30 patients (54%) had normal upper limb use after surgery, versus 8 (5%) before. CONCLUSION The study hypothesis was on the whole confirmed in terms of survival according to type of primary and whether surgery was indicated preventively or for fracture. LEVEL OF EVIDENCE IV, retrospective study without control group.

Int J Surg Case Rep 2020; 75:53-60. [PMID: 32919330 PMCID: PMC7490996 DOI: 10.1016/j.ijscr.2020.08.052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 08/26/2020] [Accepted: 08/26/2020] [Indexed: 11/29/2022] Open
Abstract
Forequarter amputation is still used in orthopedic oncology as a treatment of last resort. “Whoops” fixation refers to fracture fixation without investigating possible underlying conditions. Oncological scenario must be ruled out in fractures preceded by trivial trauma. Publishing such cases can participate in increasing the awareness of such cases and how to properly manage them.
Introduction Even with the advancement of limb salvage surgery techniques, forequarter amputation (FQA) is still used in orthopedic oncology. Even though it might pose catastrophic sequelae on the patient’s lifestyle, debilitating one’s ability to perform regular tasks, FQA is still considered as a treatment of last resort for huge fungating tumors of the upper extremity. Case presentation We present a case of an 18-year-old male patient, who was diagnosed in Libya with left proximal humerus fracture after a trivial trauma and underwent open reduction and internal fixation using k-wires as it was thought to be a simple fracture. Soon after, pain and swelling progressed severely and an open biopsy confirmed a diagnosis of osteosarcoma and imaging suggested metastatic disease to the lungs for which he was started on chemoradiotherapy. He was referred to our cancer center to continue his management and due to the aggressive nature of the tumor, the patient underwent palliative forequarter amputation followed by multiple lines of chemotherapy and radiotherapy, all of which failed to halt the progression of the disease. The patient was lost to follow up due to his decision to go back to Libya. Conclusion “Whoops” surgeries are fixated upon repairing fractures without looking for the alarming signs on radiographs to exclude pathological entity. As in our case, the procedure done escalated the osteosarcoma into such a massive fungating tumor due to the violation of the osteosarcoma pseudo capsule, in which the only available option is to do a palliative forequarter amputation.

Abstract
SummaryBone sarcomas are rare, representing only 0.2% of all diagnosed cancers. Incidence is higher in children and adolescents, but bone sarcomas are still numerically outnumbered by benign bone tumors in this patient cohort. This article summarizes the management of treatment for bone sarcomas. Systemic therapy, surgical therapy, and radiotherapy are presented. Osteosarcoma, chondrosarcoma, and Ewing sarcoma are among the most frequently occurring bone sarcomas in all age groups. In recent decades, multimodal treatment of these rare entities has increased disease-free survival for these patients. As malignant primary bone tumors are rare cancers, and since management is complex, the standard of treatment should be performed by reference centers. If possible, wide en-bloc resection of the bone sarcoma should be performed. The role of radiotherapy in osteosarcoma and chondrosarcoma is limited, but Ewing sarcoma is a radiation-responsive tumor. In primary bone sarcomas, the efficacy of chemotherapy varies according to histological type. Prognosis is poor in patients with osteosarcoma or Ewing’s sarcoma if surgery without neoaqdjuvant chemotherapy is performed. Despite advances in surgical, medical, and radiation therapy, few significant positive changes in overall survival have been observed in patients with these diseases in recent decades.

Abstract
INTRODUCTION Skeletal metastases can weaken the bone, necessitating surgery, and surgical treatment options vary. The aim of this study was to investigate the revision rate of reconstructions in surgically treated diaphyseal skeletal metastases. MATERIALS AND METHODS Between 2000 and 2018 at Helsinki and Tampere university hospitals in Finland, a total of 164 cases with diaphyseal skeletal metastases were identified from a prospectively maintained database. Tumor location was humerus, femur, and tibia in 106 (65%), 53 (32%), and 5 (3.0%) cases, respectively. A total of 82 (50%) cases were treated with intramedullary nailing (IMN), 73 (45%) with IMN and cementation, and 9 (5%) with another technique. RESULTS In the upper extremity, implant survival (IS) was 96.4% at 1, 2, and 5 years; in the lower extremity, it was 83.8%, 69.1%, and 57.6% at 1, 2, and 5 years, respectively. Lower extremity IS for impending lesions was 100% at 1, 2, and 5 years, and in cases operated for true pathologic fracture, it was 71.6%, 42.9%, and 21.5% at 1, 2, and 5 years, respectively. In IMN cases without cement, the complication rate was 16% (13/82) when compared to 6% (4/73) in IMN cases with cementation. DISCUSSION We would advocate for early intervention in patients with metastatic bone disease affecting the femur rather that watchful waiting with the risk for fracture and the need for urgent intervention. However, this choice must be balanced against the underlying risk of surgical intervention in a potentially fragile population with often limited prognoses.

[PMID: 30847272 PMCID: PMC6389683 DOI: 10.1016/j.jbo.2019.100225] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2018] [Revised: 02/12/2019] [Accepted: 02/12/2019] [Indexed: 12/23/2022] Open
Abstract
Background Operative fixation for femoral metastatic bone disease is based on the principles of reducing pain and restoring function. Recent literature has proposed a number of prognostic models for appendicular metastatic bone disease. The aim of this study was to compare the accuracy of proposed soring systems in the setting of femoral metastatic bone disease in order to provide surgeons with information to determine the most appropriate scoring system in this setting. Methods A retrospective cohort analysis of patients who underwent surgical management of femoral metastatic bone disease at a single institution were included. A pre-operative predicted survival for all 114 patients was retrospectively calculated utilising the revised Katagiri model, PathFx model, SSG score, Janssen nomogram, OPTModel and SPRING 13 nomogram. Univariate and multivariate Cox regression proportional hazard models were constructed to assess the role of prognostic variables in the patient group. Area under the receiver characteristics and Brier scores were calculated for each prognostic model from comparison of predicted survival and actual survival of patients to quantify the accuracy of each model. Results For the femoral metastatic bone disease patients treated with surgical fixation, multivariate analysis demonstrated a number of pre-operative factors associated with survival in femoral metastatic bone disease, consistent with established literature. The OPTIModel demonstrated the highest accuracy at predicting 12-month (Area Under the Curve [AUC] = 0.79) and 24-month (AUC = 0.77) survival after surgical management. PathFx model was the most accurate at predicting 3-month survival (AUC = 0.70) and 6-month (AUC = 0.70) survival. The PathFx model was successfully externally validated in the femoral patient dataset for all time periods. Conclusions Among six prognostic models assessed in the setting of femoral metastatic bone disease, the present study observed the most accurate model for 3-month, 6-month, 12-month and 24-month survival. The results of this study may be utilised by the treating surgical team to determine the most accurate model for the required time period and therefore improve decision-making in the care of patients with femoral metastatic bone disease.

Abstract
BACKGROUND Metastatic lesions to the proximal femur occur frequently and require special consideration due to the high risk of pathologic fractures. Type of surgery might influence patient survival considering the growing concept of oligometastases. In fact, the use of modular tumor megaprosthesis is increasing in the last decades compared to intramedullary nailing. Aim of this study was to evaluate oncological and functional results of treatment in patients with pathologic or impending fracture of the proximal femur, with patient survival being the primary, complications the secondary, and functional results the tertiary endpoint. METHODS Between 2016 and 2017, 40 patients with pathologic fracture (29 cases) or impending fracture according to the Mirels score (11 cases) of the proximal femur, were treated in our Institute and prospectively collected. There were 29 females (72.5%) and 11 males (27.5%), with a mean age at diagnosis of the metastasis of 63.6 years (range 35 to 92 years). Patients were treated due to bone metastases (commonly develop from breast cancer) or hematologic malignancies. Considering number of lesions, 17 patients had less than three bone metastases. Surgical procedures included intramedullary nailing (7 patients), conventional endoprosthesis (4 patients) and modular endoprosthetic replacement (29 patients). Adjuvant treatments included chemotherapy (13 cases), radiation therapy (8 cases) or both (15 cases), and selective arterial embolization (6 pre-op). Oncological results were evaluated considering the survival of patients. Functional results were assessed as pain intensity in VAS score and MSTS score. RESULTS The mean follow-up of patients was 10.2 months (range 6-26.3 years). At the latest evaluation, 23 patients were alive with disease, 3 patients were alive without evidence of disease and 14 patients were dead with disease. There was a significant better survival in patients treated with PFR compared to IMN and EPR groups (p = 0.0080). No differences in term of survival were found comparing impending vs actual pathological fracture and oligo vs multiple metastases. After surgery, all patients experienced improvement in quality of life resulting from reduction in pain. Mean MSTS score was 22.4. The overall complications rate was 22.5%. The most frequent complication was dislocation followed by wound dehiscence and deep infections. CONCLUSION Modular tumour prosthesis for proximal femur replacement provides good functional outcome, relative low incidence of complications and higher life quality in the medium term. Oncologic results were influenced by type of surgery, biased by the correct indications for resection and nailing. Preoperative general health condition, life expectancy and ambulatory capacity may influence treatment strategy. With the numbers available, the patients with actual pathologic or impending fracture of the proximal femur treated with resection had a significantly higher survival, especially those with metastases from renal carcinoma or multiple myeloma.

External Beam Irradiation Preferentially Inhibits the Endochondral Pathway of Fracture Healing: A Rat Model. Clin Orthop Relat Res 2018; 476:2076-2090. [PMID: 30024459 PMCID: PMC6259865 DOI: 10.1097/corr.0000000000000395] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/31/2023]
Abstract
BACKGROUND External beam irradiation is an accepted treatment for skeletal malignancies. Radiation acts on both cancerous and normal cells and, depending on the balance of these effects, may promote or impair bone healing after pathologic fracture. Previous studies suggest an adverse effect of radiation on endochondral ossification, but the existence of differential effects of radiation on the two distinct bone healing pathways is unknown. QUESTIONS/PURPOSES The purpose of this study was to investigate the differential effects of external beam irradiation on endochondral compared with intramembranous ossification with intramedullary nail and plate fixation of fractures inducing the two respective osseous healing pathways through assessment of (1) bone biology by histomorphometric analysis of cartilage area and micro-CT volumetric assessment of the calcified callus; and (2) mechanical properties of the healing fracture by four-point bending failure analysis of bending stiffness and strength. METHODS Thirty-six male Sprague-Dawley rats underwent bilateral iatrogenic femur fracture: one side was repaired with an intramedullary nail and the other with compression plating. Three days postoperatively, half (n = 18) received 8-Gray external beam irradiation to each fracture. Rodents were euthanized at 1, 2, and 4 weeks postoperatively (n = 3/group) for quantitative histomorphometry of cartilage area and micro-CT assessment of callus volume. The remaining rodents were euthanized at 3 months (n = 9/group) and subjected to four-point bending tests to assess stiffness and maximum strength. RESULTS Nailed femurs that were irradiated exhibited a reduction in cartilage area at both 2 weeks (1.08 ± 1.13 mm versus 37.32 ± 19.88 mm; 95% confidence interval [CI] of the difference, 4.32-68.16 mm; p = 0.034) and 4 weeks (4.60 ± 3.97 mm versus 39.10 ± 16.28 mm; 95% CI of the difference, 7.64-61.36 mm; p = 0.023) compared with nonirradiated fractures. There was also a decrease in the volume ratio of calcified callus at 4 weeks (0.35 ± 0.08 versus 0.51 ± 0.05; 95% CI of the difference, 0.01-0.31; p = 0.042) compared with nonirradiated fractures. By contrast, there was no difference in cartilage area or calcified callus between irradiated and nonirradiated plated femurs. The stiffness (128.84 ± 76.60 N/mm versus 26.99 ± 26.07 N/mm; 95% CI of the difference, 44.67-159.03 N/mm; p = 0.012) and maximum strength (41.44 ± 22.06 N versus 23.75 ± 11.00 N; 95% CI of the difference, 0.27-35.11 N; p = 0.047) of irradiated plated femurs was greater than the irradiated nailed femurs. However, for nonirradiated femurs, the maximum strength of nailed fractures (36.05 ± 17.34 N versus 15.63 ± 5.19 N; 95% CI of the difference, 3.96-36.88 N; p = 0.022) was greater than plated fractures, and there was no difference in stiffness between the nailed and plated fractures. CONCLUSIONS In this model, external beam irradiation was found to preferentially inhibit endochondral over intramembranous ossification with the greatest impairment in healing of radiated fractures repaired with intramedullary nails compared with those fixed with plates. Future work with larger sample sizes might focus on further elucidating the observed differences in mechanical properties. CLINICAL RELEVANCE This work suggests that there may be a rationale for compression plating rather than intramedullary nailing of long bone fractures in select circumstances where bony union is desirable, adjunctive radiation treatment is required, and bone stock is sufficient for plate and screw fixation.

Abstract
Background The most appropriate treatment of pathological fractures from metastatic disease depends on several factors, one of the most important being predicted life expectancy. The aim of this study was to identify the variables that influence prognosis and utilise these to develop a novel scoring system to better predict life expectancy post-pathological fracture. Methods The records of all patients that presented with metastatic pathological fractures over a 10-year period from the only tertiary orthopaedic departments in Western Australia were retrospectively examined. Variables assessed were primary cancer type, fracture site, fixation method, cement augmentation, pre-morbid level of physical functioning, complication rate, treatment with chemotherapy or radiotherapy and appendicular, spinal and visceral metastatic load. Results A total of 233 patients were included. Median survival from fracture to death was 4.1 months. Median time from cancer diagnosis to pathological fracture was 14.2 months. There was a statistically significant association between patient survival and primary cancer type, physical functional score, spinal metastatic burden and use of chemotherapy or radiotherapy. Conclusion A novel scoring system has been developed that offers a survival probability based on patient’s individual circumstances. This can guide specialist management and offer patients a more accurate expectation of functional outcome and survival time.

Abstract
BACKGROUND We introduced a palliative joint-preserving surgery using proximal self-locking screws of intramedullary (IM) nail and percutaneous cementoplasty (PC) in patients with proximal humeral metastases, including the head and neck, and evaluated the outcome of the surgical method. METHODS Twenty-three patients (mean age = 63.0 ± 11.8 years, M:F = 14:9) had IM nailing with a self-locking screw system and PC for the treatment of humeral head and neck metastases. Usually, three proximal locking screws were inserted after IM nailing, and 20.9 ± 8.0 ml of polymethylmethacrylate (PMMA) bone cement was injected in the perimetal osteolytic area. RESULTS Regional anesthesia with interscalene block was performed in 87.0% (20/23), and the duration of surgery (from anesthesia to awakening) was approximately 40-55 min. Red blood cell was not transfused intra- and/or postoperatively in 65.2% (15/23). The localized preoperative pain (visual analog scale (VAS), 8.2 ± 3.1) was gradually decreased at postoperative 1 week (VAS, 4.9 ± 2.1) and at 6 weeks (VAS, 2.9 ± 2.1) (P < 0.001). Among nine patients who underwent F-18-FDG PET/CT, the proximal humeral metastasis around PC showed improved, stable, and aggravated states in five (55.6%), three (33.3%), and one patient (11.1%), respectively. Meanwhile, 88.8% (8/9) of patients showed aggravation at the naive bone metastasis area. CONCLUSION The selection of the self-locking screw type of the IM nail and PC was helpful in preventing fixation failure for joint-preserving palliative surgery in the proximal humeral metastasis.

Abstract
Oncological management of skeletal metastases has changed dramatically in the last few decades. A significant number of patients survive for many years with their metastases. Surgeons are more active and the technical repertoire is broader, from plates to intramedullary devices to (tumour) endoprostheses. The philosophy of treatment should be different in the case of a trauma-related fracture and a pathological fracture. A proper algorithm for establishing a diagnosis and evaluation of prognostic factors helps in planning the surgical intervention. The aim of palliative surgery is usually to eliminate pain and to allow the patient to regain his/her mobility as well as to improve the quality of life through minimally invasive techniques using life-long durable devices. In a selected group of patients with an oncologically controlled primary tumour site and a solitary bone metastasis with positive prognostic factors, which meet the criteria for radical excision (approximately 10% to 15% of the cases), a promising three to five years of survival may be achieved, especially in cases of metastases from breast and kidney cancer. Spinal metastases require meticulous evaluation because decisions on treatment mostly depend on the tumour type, segmental stability, the patient’s symptoms and general state of health. Advanced radiotherapy combined with minimally invasive surgical techniques (minimally invasive stabilisation and separation surgery) provides durable local control with a low complication rate in a number of patients.

Abstract
PURPOSE Pathologic fractures occur in 5-10% of pediatric osteosarcoma (OS) cases and have historically been considered a contraindication to limb salvage. Our purpose was to describe the radiographic features of pathologic fracture and examine its impact on local recurrence rates, functional outcomes, and overall survival. METHODS We retrospectively analyzed patients at our institution from 1990 to 2015 with pathologic fracture at diagnosis or during neoadjuvant chemotherapy. We selected a control group of 50 OS patients of similar age and gender without pathologic fracture from 1990 to 2015. Functional outcomes were scored using Musculoskeletal Tumor Society criteria. Chi-square test was used for comparative analysis of groups. RESULTS Thirty-six patients with 37 pathologic fractures form the study cohort. Of patients who received surgery, 18 of 34 patients with fracture underwent amputation compared to 8 of 48 patients in the nonfracture group (P = 0.007). Indications for amputation in fracture patients were tumor size (n = 7), neurovascular involvement (n = 6), and tumor progression during neoadjuvant chemotherapy (n = 5). Only one patient (2.9%) in the fracture group who underwent limb salvage suffered local recurrence. Of patients who received neoadjuvant chemotherapy, 25 of 34 fracture patients showed poor histological response compared to 24 of 47 nonfracture patients (P = 0.044). There was no statistically significant difference in overall survival (P = 0.96). Functional outcomes were significantly lower in fracture patients (median = 17.5) than nonfracture patients (median = 24) (P = 0.023). CONCLUSIONS Radiographic features of pathologic fractures were highly variable in this population. Limb salvage surgery can be performed without increased risk of local recurrence. Patients with pathologic fracture suffer worse functional outcomes but no decrease in overall survival.

Abstract
BACKGROUND Metastatic disease is the most common malignancy of the bone. Prostate, breast, lung, kidney, and thyroid cancer account for 80% of skeletal metastases. Bone metastases are associated with significant skeletal morbidity including severe bone pain, pathologic fractures, spinal cord or nerve roots compression, and malignant hypercalcemia. These events compromise greatly the quality of life of the patients. The treatment of cancer patients with bone metastases is mostly aimed at palliation. OBJECTIVE This article aims to present these palliative treatments for the patients with bone metastases, summarize the clinical applications, and review the techniques and results. METHODS It gives an extensive overview of the possibilities of palliation in patients with metastatic cancer to the bone. RESULTS AND DISCUSSION Currently, modern treatments are available for the palliative management of patients with metastatic bone disease. These include modern radiation therapy, chemotherapy, embolization, electrochemotherapy, radiofrequency ablation, and high-intensity focused ultrasound. As such it is of interest for all physicians with no experience with these developments to make palliative procedures safer and more reliable.

Abstract
PURPOSE To provide treatment guidelines for patients with long bone metastatic disease based on a systematic review of the literature and to propose an algorithm to guide orthopedic surgeons in decision-making for these patients. MATERIALS AND METHODS We performed a computerized literature search in MEDLINE, EMBASE and Scopus for studies on patients with long bone metastases. We used the key words "long bones", "metastasis" and "treatment" for published studies that evaluated any treatment for long bone metastases. The articles found were then studied to determine the accuracy of surgical treatments for long bone metastases in every anatomic location, regardless of cancer type, stage and grade of the oncologic disease. Guidelines inferred from this literature review were collected, and an algorithm was proposed. RESULTS There was no clear evidence to support excision of a long bone metastatic lesion at the same surgical setting with internal fixation or prosthetic reconstruction. However, en bloc resection of an isolated bone metastasis may have a beneficial effect on survival. The life expectancy of the patients should be considered for any surgical treatment. Internal fixation preferably with reconstruction nails is indicated for meta-diaphyseal lesions; their rate of mechanical failure and complications ranges from 2 to 22 %. Prosthetic reconstruction is indicated for extensive lytic lesions or pathologic fractures in a meta-epiphyseal locations; their rate of mechanical failure and complications ranges from 3.7 to 35 %. Most of the internal fixation-related complications occur more than 1 year after treatment, in contrast to prosthetic reconstruction-related complications that may occur earlier. CONCLUSIONS Intramedullary nail fixation or prosthetic reconstruction should be chosen on the basis of the location of the lesion, the extent of bone destruction and the stability of the construct to outlast the expected life of the patient. Implant-related complication is similar but may occur earlier with prosthetic reconstructions.

Abstract
Aims The purpose of the study was to investigate whether closed intramedullary (IM) nailing with percutaneous cement augmentation is better than conventional closed nailing at relieving pain and suppressing tumours in patients with metastases of the femur and humerus. Patients and Methods A total of 43 patients (27 men, 16 women, mean age 63.7 years, standard deviation (sd) 12.2; 21 to 84) underwent closed IM nailing with cement augmentation for long bone metastases. A further 27 patients, who underwent conventional closed IM nailing, served as controls. Pain was assessed using a visual analogue scale (VAS) score pre-operatively (pre-operative VAS), one week post-operatively (immediate post-operative VAS), and at six weeks post-operatively (follow-up post-operative VAS). Progression of the tumour was evaluated in subgroups of patients using F-18-fludeoxyglucose (F-18-FDG) positron emission tomography (PET)/computed tomography (CT) and/or bone scintigraphy (BS), at a mean of 8.8 and 7.2 months post-operatively, respectively. Results The mean pain scores of patients who underwent closed nailing with cement augmentation were significantly lower than those of the control patients post-operatively (immediate post-operative VAS: 3.8, sd 0.9 versus 6.0, sd 0.9; follow-up post-operative VAS: 3.3, sd 2.5 versus 6.6, sd 2.2; all p < 0.001). The progression of the metastasis was suppressed in 50% (10/20) of patients who underwent closed nailing with augmentation, but in only 8% (1/13) of those in the control group. Conclusion Percutaneous cement augmentation of closed IM nailing improves the relief of pain and limits the progression of the tumour in patients with metastases to the long bones. Take home message: Percutaneous cement augmentation while performing closed IM nailing has some advantages for long bone metastases. Cite this article: Bone Joint J 2016;98-B:703–9.

Reconstruction of the proximal femur with a modular resection prosthesis. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2016; 26:415-21. [PMID: 27040404 DOI: 10.1007/s00590-016-1764-0] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2015] [Accepted: 03/14/2016] [Indexed: 02/08/2023]
Abstract
BACKGROUND Various megaprostheses are currently available for reconstruction of the proximal femur after tumor resection. This study evaluates the survival and complications of a modular megaprosthesis for reconstruction of the proximal femur. MATERIALS AND METHODS We studied the medical files of 109 tumor patients (age range 16-86 years) who underwent proximal femoral reconstruction with the MRP(®) megaprosthesis from 2002 to 2011. There were 70 patients with metastases, 34 patients with bone sarcomas, and five patients with hematological malignancies; 82 were primary and 27 were revision reconstructions. Mean follow-up was 2.5 years; 31 patients had a minimum five-year follow-up. We evaluated the survival and function of the patients, and the survival and complications of the megaprostheses. RESULTS Survival was significantly higher for the patients with bone sarcomas compared to those with metastases and hematological malignancies. Mean MSTS functional score was similar between patients with bone sarcomas and those with hematological malignancies and metastases, and between patients with primary and those with revision reconstructions. Overall survival of the MRP(®) megaprostheses was 74 % at 5 and 9 years. Fourteen (13.6 %) major complications occurred at a mean period of 1.4 years (range 3 months to 4.5 years); these included infection (5.8 %), dislocation (3.9 %), local recurrence (2.9 %), and acetabular fracture (1 %). CONCLUSION MRP(®) megaprostheses are a valuable reconstruction option after tumor resection of the proximal femur.

Abstract
AIM Establishing an early and accurate diagnosis in cases of suspected pathological fractures is crucial to initiate optimal treatment without delay. The use of percutaneous biopsy has become popular over the past few years. However, there is a paucity of information regarding the efficacy and safety of percutaneous biopsy procedures guided by fluoroscopy. METHODS A total of 137 percutaneous C-arm fluoroscopy-guided core needle biopsy (CNB) procedures were performed in 135 patients with suspected pathological fractures. The sensitivity, specificity, accuracy, and overall prognostic value of these procedures were evaluated. Complications, if any, were documented for all cases. RESULTS The overall sensitivity, specificity, and accuracy were 82.0%, 100%, and 83.2%, respectively. The positive and negative predictive value was 100% and 28.1%, respectively. There were 23 "false negative" cases in our study, of which 15 were benign lesions and eight were malignant tumors. No "false-positives" were found. Major procedure-related complications occurred in three patients (2.2%). These complications, however, did not alter the prognosis of these patients. CONCLUSION Percutaneous C-arm fluoroscopy-guided biopsy procedures are both effective and safe for diagnosis of suspected pathological fractures in the appendicular skeleton.

The investigation and management of suspected malignant pathological fractures: a review for the general orthopaedic surgeon. Injury 2015; 46:1891-9.

Abstract
The management of malignant pathological fractures necessitates careful diagnostic work-up, pre-operative investigation, planning and multidisciplinary input from specialists in the fields of radiology, pathology, oncology, trauma and orthopaedics. Malignant and non-malignant conditions including metabolic disorders, benign tumours and pharmacological therapies can be implicated. The majority of patients who present with suspected pathological fractures will be managed by general orthopaedic and trauma surgeons rather than specialists in orthopaedic oncology. Skeletal metastases can result in considerable morbidity and predispose to pathological fractures. With advances in the medical management of malignancy, life expectancy in cancer patients is increasing, leading to an increasing risk of skeletal metastasis and the potential for pathological fractures. Conventional modes of trauma fixation for pathological fractures may not be appropriate. The aim of this review is to outline diagnostic and management strategies for patients who present with a long bone fracture that is potentially pathological in nature.

Abstract
BACKGROUND Pathological fractures are a significant and often devastating event in the progression of metastatic bone disease. They are frequently a marker of end-stage cancer and the end of functional independence. Although several studies look into prognosis following the development of metastatic lesions, few look into the prognosis after the fracture itself. This study investigates the variables affecting prognosis in patients suffering pathological fractures. METHOD Retrospective clinical audit of 72 patients from the Orthopaedic Unit at Fremantle Hospital in Western Australia. The variables of interest include primary cancer, fracture site, method of fixation, use of cement augmentation, appendicular metastatic load, spinal metastatic load, presence of visceral metastases, patient co-morbidities and functional scoring before and after the fracture has occurred. RESULTS The median time between diagnosis of cancer to pathological fracture was 8.3 months, while the median survival post-fracture was 3.3 months. There is a statistically significant correlation between patient survival and primary cancer type, spinal metastatic burden and functional performance score. CONCLUSION Overall, the prognosis following pathological fracture is extremely poor. We propose that these variables are scrutinized by the treating orthopaedic team preoperatively to help guide management and provide patients and their families with a realistic expectation of functional outcome and survival time.

Abstract
Advances in adjuvant and neoadjuvant therapies have improved the prognosis of cancer patients leading to an increasing incidence of bone metastases and consequent long bone fractures. In the present study the authors consider the indications and the different surgical options of treatment of tibial pathological lesions. 13 patients (14 lesions, 6 pathological fractures), treated according to histotype and lesion localisation, were retrospectively evaluated. Using generic outcome instruments such as the Eastern Cooperative Oncology Group (ECOG) and Quality of life questionnaire of European Organization for Research and Treatment of Cancer (QLQ-C30) pain, mobility and use of analgesics were evaluated before and after surgery. In all patients, mechanical stabilisation of the osteolytic lesion was achieved. There were no pathological fractures, and no implant mechanical failure. All patients reported pain relief, with a relevant reduction in the amount of analgesics used. Surgical treatment of tibial metastases has to be decided taking into consideration the histotype, localisation of the metastases and life expectancy. The treatment has to be all-encompassing in a solitary lesion in patients with a good prognosis but less invasive in plurimetastatic patients with poor prognosis. Acquisition of good mechanical stability is crucial for a successful outcome.

Abstract
OBJECTIVE This study tested the implication of pathologic fractures on the prognosis in stage IIb osteosarcoma. METHODS A single center retrospective evaluation of clinical management and oncologic outcome was conducted with 15 pathological fracture patients (M:F = 10:5; age: mean 23.2, range 12-42) and 50 non-fracture patients between April 2002 and December 2010. These stage IIB osteosarcoma patients were matched for age, tumor site (femur, tibia, and humerus), and osteosarcoma subtype (i.e., control patients with osteosarcoma in the same sites as the fracture patients). All osteosarcoma patients with pathological fractures underwent brace or cast immobilization, adjuvant chemotherapy, and limb salvage surgery or amputation. Musculoskeletal Tumor Society (MSTS) functional scores were assessed. The mean follow-up time was 34.7 months (range, 8-47 months). RESULTS Following limb salvage surgery, no statistical differences were observed in major complications (fracture = 20.0%, control = 12.0%, P = 0.43) or local recurrence complications (fracture = 26.7%, control = 14.0%, P = 0.25). Overall 3-year survival rates of the fracture and control groups (66.7% and 75.3%, respectively) were not statistically different (P = 0.5190). Three-year disease-free survival rates of the fracture and control groups were 53.3% and 66.5%, respectively (P = 0.25). CONCLUSIONS Pathologic fracture was not a prognostic indicator of recurrence or overall survival in localized osteosarcoma patients. Limb salvage can be achieved by and maintaining adequate surgical margins and applying adjuvant chemotherapy.

Abstract
Radiation therapy and chemotherapy, while they remain an essential part of the multidisciplinary treatment of cancers, they have led to unwanted complications. Radiation-induced complications include wound and bone, growth, nervous system, tumorigenic, lung, gastrointestinal, hepatic and other complications. In this article we review the side effects of radiation therapy in musculoskeletal oncology emphasizing on bone, present our long experience, and discuss the current literature regarding radiation-induced bone complications and their management and outcome.

Abstract
BACKGROUND Previous studies reported on surgical indications for patients with femoral metastases. However, few studies analyzed the spectrum of femoral metastatic presentation. We performed this study to evaluate the survival of patients with femoral metastases, and clarify the treatment of femoral impending and actual pathological fractures. MATERIALS AND METHODS We retrospectively studied 110 patients with femoral metastases from various cancers treated with nailing or resection and megaprosthetic reconstruction from 1995 to 2010. The mean follow-up was 18 months. Survival was analyzed with respect to different metastatic presentations regarding gender, type of cancer, number, and location of femoral metastases, type of surgery, and pathological fracture. RESULTS Univariate predictors of survival were the pathological fracture and type of surgery; multivariate predictor was only the pathological fracture. Survival was significantly higher in patients with resection compared to nailing, impending compared to actual fracture, solitary metastasis and impending fracture, actual fracture treated with resection, proximal femoral actual fracture and distal femoral impending fracture treated with resection. CONCLUSIONS Patients with femoral metastases have better survival when present with impending compared to actual pathological fracture. Although with a higher rate of complications, patients with pathological fractures of the proximal and distal femur may benefit from resection.
