Treatment Of Pathological Fractures Research Articles

Conservative treatment of pathological fracture after multiple odontogenic keratocyst surgery: a case report and literature analysis.

Pathological fractures after jaw cyst surgery are rare clinically but are a serious complication. Once a pathological fracture occurs, treatment time and economic costs increase, and doctors face difficulty in handling it. This article reports a case of a patient with mandibular pathological fractures after multiple odontogenic keratocyst surgery of the jaw. Mandibular lesions were located in the bilateral mandibular angles and had macrocystic changes. We adopted a conservative treatment plan, and the treatment effect was good. We also discussed and analyzed relevant literature to provide a reference for clinicians.

Pathological fractures of the extremities

The diagnostics and treatment of pathological fractures of the extremities differ from the approach for conventional fractures. Metastases from breast, bronchial, renal cell and prostate cancer are the predominant cause. Typically, patients present at over 50years old present after an inadequate trauma. They often report symptoms or swelling in the affected region that already existed before the fracture. An underlying malignant disease is sometimes already known; however, occasionally this is manifested in the form of a fracture. The femur is affected in 74% of cases, followed by the humerus and the tibia. Important indications for the presence of apathological fracture can even be obtained from conventional radiographs. The diagnostics are supplemented with further modalities depending on the treatment goal. Surgical treatment is the first choice as the fractures do not heal using conservative measures. In this context, aprognosis-stratified approach is recommended.

Pathological Fractures in Aneurysmal Bone Cysts: A Systematic Review.

Background: Aneurysmal bone cysts (ABCs) are osteolytic, non-malignant, vascular lesions of the bone. Pathological fractures can be a manifestation of the ABCs, which occur in about 8% of ABCs. Different treatments have been described in the literature, but, nowadays, an optimal management of the pathological fractures in patients with ABCs is still a matter of debate and there are no standard guidelines for treatment nor any shared indication about the best surgical intervention. The aim of our study is to review the current literature available on this matter exploring and confronting different surgical treatments for pathological fractures in ABC in order to clarify the surgical approach to these patients. Methods: A systematic review of the literature indexed in PubMed, MEDLINE, and Cochrane Library databases was carried out. The Preferred Reporting Items for Systematically Reviews and Meta-Analyses (PRISMA) were followed. Results: A total of 37 articles were relevant and were finally included in the study. In total, we reached a population of 140 patients. Of the 140 patients included in the review, 124 patients (88.6%) underwent curettage surgery, 15 patients (10.7%) underwent en bloc resection surgery. A total of 47% of patients (70) underwent synthesis surgery with a plate, screw, nail, or external fixator. Adjuvant treatments were used in 8.6% of patients (12). Complications involved 20.7% of the patients (29). Conclusions: In conclusion, the treatment of pathological fractures in aneurysmal bone cysts requires careful patient assessment, considering factors such as age, the presence of open growth plates, the location of the lesion, and the surgeon's expertise.

Intravenous tranexamic acid reduces complications following surgical treatment of pathologic fractures of the lower extremity.

This study aimed to evaluate the postoperative complications associated with administering intravenous (IV) tranexamic acid (TXA) in patients undergoing surgical fixation for neoplastic pathologic fractures of the lower extremities. Patients ≥18 years old who underwent surgical intervention for neoplastic pathologic lower extremity fractures from 2015 to 2021 were identified using the Premier Healthcare Database. This cohort was divided by TXA receipt on the index surgery day. Patient demographics, hospital factors, patient comorbidities, and 90-day complications were assessed and compared between the cohorts. From 2015 to 2021, 4497 patients met inclusion criteria (769 TXA[+] and 3728 TXA[-]). Following propensity score matching, patients who received TXA had a significantly shorter length of stay than those who did not (7.6 ± 7.3 days vs. 9.0 ± 15.2, p = 0.036). Between the two cohorts, there were no significant differences in comorbidities. Regarding differences in postoperative complications, TXA(+) patients had significantly decreased odds of deep vein thrombosis (DVT) (1.87% vs. 5.46%; odds ratio [OR]:0.33; 95% confidence interval: 0.17-0.62; p = 0.001). Administration of IV TXA may be associated with a decreased risk of postoperative DVT without an increased risk of other complications. Orthopedic surgeons should consider the utilization of IV TXA in patients treated surgically for neoplastic pathologic fractures of the lower extremity.

Percutaneous calcium sulfate injection versus localized scrape bone grafting: clinical effect comparison in titanium elastic nail treatment of pathological fracture of proximal humerus caused by unicameral bone cysts in children.

A retrospective study was conducted to compare the mid-term clinical efficacy between percutaneous calcium sulfate injection (PCSI) and localized scrape bone grafting (LSBG) in using titanium elastic nails treat humerus pathologic fractures caused by unicameral bone cysts in children. Humerus pathologic fracture patients with unicameral bone cysts in our pediatric orthopedic department from January 2015 to January 2020 were retrospectively analyzed. Patients were divided into two groups, namely the PCSI group and the LSBG group, based on the type of bone grafting material they received. Preoperative assessments were made in both groups using the Cyst Index and Cyst activity. During the perioperative phase, assessments were made regarding operative time, bleeding, postoperative VAS scores, and the frequency of reoperation within 2 years. Clinical outcomes were evaluated using the Capanna scale at the last follow-up, and the occurrence of re-fractures during the follow-up period. A total of 22 patients were included, with a mean follow-up duration of 33.5 ± 5.8 months. No significant differences were found between the two groups in terms of Cyst Index and Cyst activity before the operation. The operative time, bleeding, and postoperative VAS scores in the PCSI group were found to be lower than those in the LSBG group (P < 0.05). The PCSI group also showed a higher frequency of reoperation within 2 years compared to the LSBG group (P < 0.05). However, no significant differences were observed between the two groups in terms of Capanna scale scores at the last follow-up and the incidence of re-fractures during follow-up. Both titanium elastic nails (TEN) combined with PCSI or LSBG were found to be safe and effective treatments for humerus pathologic fractures caused by unicameral bone cysts in children. PCSI is considered as a less invasive option with shorter operative times, less bleeding, and reduced postoperative pain, although it comes with the risk of multiple injections. On the other hand, LSBG is considered as a more invasive option for the treatment of active bone cysts but is associated with a lower recurrence rate.

Biomechanics in Pathological Fractures

In the setting of a benign or malignant lesion the altered physiology and mechanics may lead to pathological fractures. Patient outcome depends on proper diagnosis, staging and treatment of pathological fractures. On conventional X rays or computed tomography scan (CT) images it becomes extremely difficult to assess the clinical fracture risks. Accurate predication can’t be made by experienced clinicians

Features of routing, diagnosis and combined treatment of pathological fractures of long tubular bones of tumor etiology

Introduction. In the structure of fractures of long tubular bones, pathological fractures account for about 1 %, and 2/3 of all cases are pathological fractures associated with bone metastases. Primary bone tumors are complicated by the development of a pathological fracture in 1– 10 % of cases, bone metastases in 8–30 % of cases. With a pathological fracture, as the primary manifestation of the tumor process, as a rule, patients come to the attention of orthopedic traumatologists providing emergency care. In the practice of oncologists, there are often patients with bone tumors who have performed deliberately non-radical surgical interventions associated with insufficient oncological alertness of traumatologists.Aim. To study and present the results of combined treatment of patients with bone tumors complicated by a pathological fracture.Materials and methods. The results of treatment and observation of 159 patients with tumors of long tubular bones complicated by a pathological fracture or the threat of its development, who received combined or surgical treatment and were observed in the polyclinic of the Republican Oncological Dispensary from 2008 to 2020, were analyzed.Results. A pathological fracture that has taken place, in the absence of somatic contraindications, is not a contraindication to neoadjuvant treatment, which allows performing organ-preserving surgical treatment with optimal local and systemic control. However, with verified bone metastases, when segmental bone resections are not shown, and the diagnosis of myeloma (solitary plasmocytoma) is established, it is permissible to perform surgery in a trauma hospital, after consulting an oncologist.Conclusion. The combined approach in the treatment of malignant bone tumors complicated by a pathological fracture makes it possible to perform a functional-saving, organ-preserving surgical intervention, significantly reducing the risk of tumor recurrence and systemic progression.

Treatment of Pathological Fracture Following Unicameral Bone Cyst in Unusual Location of Proximal Radius: Rare Case Report

Unicameral bone cysts (UBCs) are benign bone lesions predominantly affecting children and teenagers. This case report highlights the rare occurrence of a simple bone cyst in the proximal radius in a 29-year-old woman with a pathological fracture. Although the proximal radius is an uncommon site for UBC occurrence, the surgical approach required special care due to the complex anatomical structures near the fracture site. The surgical management of UBCs aims to prevent or manage pathological fractures, facilitate cyst healing, prevent recurrence, and reduce the risk of refracture. Understanding the treatment options and involving patients in the decision-making process are crucial for achieving the best possible results in managing UBCs with pathological fractures. The decision to pursue nonoperative or operative treatment should be made in consultation with healthcare professionals, considering factors such as clinical presentation, radiological features, and symptoms.

Prevalence of primary malignant tumours, rates of pathological fracture, and mortality in the setting of metastatic bone disease.

The modern prevalence of primary tumours causing metastatic bone disease is ill-defined in the oncological literature. Therefore, the purpose of this study is to identify the prevalence of primary tumours in the setting of metastatic bone disease, as well as reported rates of pathological fracture, postoperative complications, 90-day mortality, and 360-day mortality for each primary tumour subtype. The Premier Healthcare Database was queried to identify all patients who were diagnosed with metastatic bone disease from January 2015 to December 2020. The prevalence of all primary tumour subtypes was tabulated. Rates of long bone pathological fracture, 90-day mortality, and 360-day mortality following surgical treatment of pathological fracture were assessed for each primary tumour subtype. Patient characteristics and postoperative outcomes were analyzed based upon whether patients had impending fractures treated prophylactically versus treated completed fractures. In total, 407,893 unique patients with metastatic bone disease were identified. Of the 14 primary tumours assessed, metastatic bone disease most frequently originated from lung (24.8%), prostatic (19.4%), breast (19.3%), gastrointestinal (9.4%), and urological (6.5%) malignancies. The top five malignant tumours resulting in long bone pathological fracture were renal (5.8%), myeloma (3.4%), female reproductive (3.2%), lung (2.8%), and breast (2.7%). Following treatment of pathological fractures of long bones, 90-day mortality rates were greatest for lung (12.1%), central nervous system (10.5%), lymphoma (10.4%), gastrointestinal (10.1%), and non-renal urinary (10.0%) malignancies. Finally, our study demonstrates improved 90-day and 360-day survival in patients treated for impending pathological fracture compared to completed fracture, as well as significantly lower rates of deep vein thrombosis, pulmonary embolism, urinary tract infection, and blood transfusion. This study defines the contemporary characteristics of primary malignancies resulting in metastatic bone disease. These data should be considered by surgeons when prognosticating patient outcomes during treatment of their metastatic bone disease.

Accompanying Therapy in the Surgical Treatment of Pathological Fractures of the Long Bones and Chronic Fractures of the Trochanteric Region

The article presents a study of palliative surgical treatment of patients with pathological fractures of the long bones and chronic trochanteric fractures. Those patients are not indicated for special oncological treatment. Therefore, the article does not provide staging of malignant neoplasms. The surgical treatment was aimed at improving the quality of life of palliative patients, and accompanying therapy in the form of the Altaicae extract adaptogen and the neutral anolyte led in our study to an increase in the effectiveness of surgical treatment of such a severe contingent of patients.INTRODUCTION According to domestic and foreign literature, the number of oncological diseases in young and old people is growing. There is a trend to neglecting the disease and late visits to doctors. Almost all types of cancer of various localization and other malignant tumors metastasize to the bones. An increase in the number of pathological (metastatic) fractures of the trochanteric region and the long bones was also noted. Surgical treatment of patients with such a severe type of fractures leads to an aggravation of the already existing immunodeficiency and, as a rule, creates the prerequisites for the occurrence of infectious complications in the postoperative period. The choice of a conservative method of treatment often does not justify itself as well, it leads to diagnostic and therapeutic errors, and in the future — to chronic pathological fractures.AIM To improve the effectiveness of surgical treatment and the quality of life of palliative patients with pathological (metastatic) fractures of the long bones and chronic trochanteric fractures using original authors’ accompanying therapy.MATERIAL AND METHODS 177 patients were examined and divided into two groups the main and the control groups. 72 patients were included in the main group, and 105 patients in the control group. There were 110 men and 67 women. The patient age ranged from 35 to 90 years. The main group received surgical treatment with the use of new accompanying therapy along with the basic one, and the control group received only surgical treatment and basic therapy.RESULTS In the main group patients with chronic pathological fractures of the trochanteric region, who underwent endoprosthetic replacement, osteosynthesis, a new method of surgical treatment of metastatic fractures of the long bones and the authors’ accompanying therapy, the effectiveness of surgical treatment increased significantly compared to the comparison group. As a result, most of the unwanted symptoms disappeared, time spent in hospital decreased, the psychoemotional status and immunity improved, the functional state of the body was optimized, and the quality of life improved.CONCLUSION The use of new accompanying therapy, the authors’ method of surgical treatment of patients with pathological (metastatic) fractures of the long bones, chronic fractures of the trochanteric region allows us to successfully and effectively operate on such severe patients and perform a fast track surgery program in the early postoperative period.

Treatment of Pathological Fracture of Radius due to Multiple Myeloma with Elastic Intramedullary Nail and Cement Augmentation: Expanding the Indications of Elastic Nails.

Pathological fractures of the proximal radius are exceedingly rare. Here, a case of an 81-year-old female diagnosed with multiple myeloma 15 years ago who suffered a pathological fracture of her left proximal radius is presented. Due to the fracture's proximity to the elbow joint and the lack of adjacent healthy bone tissue, a resourceful surgical intervention was implemented using a pediatric flexible nail supplemented by polymethacrylate cement injection. Six weeks post-operatively, the patient had alleviation of the pain with fully functional forearm. This novel approach could possibly aid in the treatment of other long bone pathological fractures due to neoplastic metastases.

Preoperative coagulation biomarkers associate with survival and pulmonary embolism after surgical treatment of non-spinal skeletal metastases

BackgroundThrombotic complications are synergistic and associated with orthopedic procedures, trauma, and malignancy. Because cancer enhances coagulation activity and vice versa, we assessed preoperative biomarkers for survival and complications after treatment of pathologic fractures in non-spinal skeletal metastases.Patients/methodsOur study population comprised 113 actual or impending pathologic fractures in 100 patients admitted to two referral centers. Laboratory variables were collected retrospectively from patient records and analyzed related to incidence of pulmonary embolism (PE) and mortality (Kaplan-Meier and Cox regression analyses and biomarker quartiles).ResultsPreoperative coagulation variables were high without exceptions. PE occurred in 12 patients at 36 post-operative days at incidence of 11% in the lower and 13% in the upper extremity fractures. Patients with fibrinogen exceeding 5 g/l (log-rank 0.022) developed PE earlier (5 to 15 days postoperatively) than others. Also, mean patient survival with normal fibrinogen range (2–4 g/l) was 34 months, whereas it halved upon elevated fibrinogen (log-rank p = 0.009). Survival in patients with FVIII levels under 326 IU/dl (Q3) was 22 months, but only 7 months if FVIII exceeded 326 IU/dl (log-rank p = 0.002). Combined elevated fibrinogen and FVIII predicted survival: for patients with levels below threshold limits was 22 months versus only 7 months when both variables exceeded the ranges (log-rank p < 0.001). Multivariate analysis to control confounders supported an independent role of fibrinogen and FVIII for survival.ConclusionsOur study has established fibrinogen and FVIII as potential preoperative contributors of survival and complications after treatment of metastatic fractures. These results highlight the need for novel anticoagulation and thromboprophylaxis strategies among these patients.

Влияние патологических переломов на лечение детей с костными саркомами

Introduction A pathological fracture in patients with primary bone sarcomas is a complication that requires specific management with the prognosis affecting the disease. The treatment strategy of the patients with pathological fracture remains controversial. The aim was to explore the effect of a pathological bone fracture on treatment of pediatric bone sarcoma. Material and methods The study included 141 children with bone sarcomas, residents of Moscow. A pathological fracture was observed in 17 (12.1 %) cases accompanied by osteosarcoma in 10 (58.8 %) cases and Ewing's sarcoma in 7 (41.2 %) cases. Long bones were most common location of the fracture seen in 15 (88.2 %) cases. Results Errors in establishing the diagnosis of bone sarcomas occurred in children with/without a fracture with no statistically significant differences (p = 0.239). There were no statistically significant differences in the volume of surgical interventions, functional assessment using the Musculoskeletal Tumor Society System (MSTS), and 5-year survival in children with/without a fracture (p ≥ 0.05). Discussion Treatment of pathological fractures in children should be produced after obtaining biopsy and the histological diagnosis. The frequency of local recurrence and functional outcome does not depend on the fracture. Conclusion Pathological process is to be ruled out in the presence of a fracture, and adequate visualization using MRI to be followed by a biopsy in a specialized institution would be needed if a pathological focus is suspected.

Radiolucent Implants for Fixation of Impending and Pathologic Fractures.

Radiolucent implants offer theoretical advantages of increased ability to evaluate the fracture site for healing and recurrence and potentially less effect on radiation treatment, avoiding scatter. Their clinical utility and outcomes have yet to be proven in a well-designed randomized trial or large cohort study, although studies based on other indications have shown relative safety and they are approved by the US Food and Drug Administration for treatment of pathologic fractures. Further research is necessary to better understand when and how these implants should be implemented in practice. [Orthopedics. 2022;45(3):e115-e121.].

748 Case Series: Experience of Using External Fixation as An Adjunct in The Management of MRONJ Affecting the Mandible

IntroductionExternal fixation was first described by Malgaigne and Rigaud in 1870 for use on long bones, then adapted for OMFS in 1934 and used for treating comminuted fractures. In recent times, popularity of external fixators has decreased with the use of mini-plates, often only used in major trauma, for example gunshot wounds. This is a case series of patients who have been treated by external fixation for medication related osteonecrosis (MRONJ) of the jaw and could be a fairly simple alternative to major reconstructive surgery in such cases. This method of treatment has been particularly useful during the Covid-19 pandemic as a non-aerosol generating procedure.MethodA single centre, retrospective study of 5 cases between December 2018 - December 2020. The MRONJ cases were graded using the AAOMS classification. All cases treated with external fixation of mandible were included. Pre-operative condition, medical history, treatment complications, pain management, length of treatment and follow-up results were recorded.ResultsOf the 5 cases treated for MRONJ, 4 of these had pathological fractures. All were AAOMS stage 3. The mean duration of treatment was 78 days, with regular clinical reviews monitoring progress. Of these cases, 4 cases healed well with significant improvement or closure of intraoral and extra-oral wounds.ConclusionsIn this small case series the technique has shown positive results; being well received by patients and allowing function while in situ. It allows treatment of pathological fractures as well as stabilising the mandible as a preventative measure whilst debriding severely atrophic mandibles.

Combined Microwave Ablation and Osteosynthesis for Long Bone Metastases.

Background and Objectives: The purpose of this study was to evaluate the feasibility, safety and efficacy of microwave ablation (MWA) in combination with open surgery nail positioning for the treatment of fractures or impending fractures of long bone metastases. Material and Methods: Eleven patients (four men, seven women) with painful bone metastases of the humerus, femur or tibia with non-displaced fractures (one case) or impending fractures (10 cases) underwent open MWA in combination with osteosynthesis by locked nail positioning. Pain intensity was measured using a VAS score before and after treatment. CT or MRI were acquired at one month before and 1, 3, 6, 12 and 18 months after treatment. Results: All procedures were successfully completed without major complications. The level of pain was significantly reduced one month after treatment. For the patients with humerus metastases, the complete recovery of arm use took 8 weeks, while for the patients with femoral metastases the complete recovery of walking capacity took 11 weeks. The VAS score ranged from 7 (4–9) before treatment to 1.5 (0–2.5) after treatment. During a mid-term follow-up of 18 months (range 4–29 months), none of the patients showed tumor relapse or new fractures in the treated site. Two patients died due to tumor disease progression. Conclusion: Results of this preliminary study suggest that combined MWA and surgical osteosynthesis with locked nails is a safe and effective treatment for pathological fractures or malignant impending fractures of long bone metastases of the humerus, femur and tibia. Further analyses with larger cohorts are warranted to confirm these findings.

Oncologic aspects in treatment of pathologic fractures

Pathological fractures are not only incisive events for tumor patients often with the need of surgical treatment but also often represent a relevant challenge in the overall concept of oncological treatment. The aim of this article is to illustrate the necessity of a pre-interventional interdisciplinary consideration of disease-specific and patient-specific characteristics. A literature search and evaluation of existing guidelines were carried out including the keywords "bone metastases" and "pathological fractures" with respect to the oncological and radiotherapeutic treatment. An essential classification of the surgical and other needs for treatment is carried out by the identification of the underlying disease and dissemination situation. For tumor-related pathological fractures a palliative treatment situation is present in most cases. Nevertheless, a possible oligometastasis and an increasing number of effective systemic treatment methods must be taken into consideration when planning the surgical treatment. In addition to the therapeutic emergency indications in spinal compression or symptomatic hypercalcemia, both additive radiotherapy and supplementary pharmaceutical osteoprotection have to be addressed in this context. Radiotherapy in particular represents an effective alternative option for symptom and tumor control. The work-up of the multifaceted oncological treatment concept represents an interdisciplinary challenge, which ideally defines the further treatment procedure, including fracture treatment, in an interdisciplinary tumor board within an overall oncological concept.

The role of puncture biopsy in the treatment of pathological fractures of the cervical vertebrae

The aim is to analyze the data obtained during biopsy of primary and secondary lesions and pathological fractures of the cervical vertebrae and their influence on the tactics of treatment of patients. Evaluation of the effectiveness of biopsy of pathological processes in the cervical vertebrae.&#x0D; Materials. The results of biopsies of 20 patients with lesions of the cervical vertebrae of unknown etiology or with the presence of pathological fractures with compression of the spinal cord and roots by a vertebra or a soft tissue component were analyzed.&#x0D; The following results were obtained: the presence of a secondary lesion of the cervical vertebrae was revealed: metastatic nature – 10, primary tumors – 1, lymphoproliferative tumors – 3, no tumor lesion was detected – 3, not enough material for the study – 3.&#x0D; Conclusion. The results obtained indicate the high efficiency and sufficient safety of puncture biopsy in diagnosing lesions of the cervical vertebrae, even in complex localizations (C2). Revealing the nature of vertebral lesions in the absence of absolute indications for decompression and stabilization interventions significantly affects the tactics and order of treatment of the patient.
