Aims. 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. Methods. 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. Results. 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. Conclusion. 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. Cite this article: Bone Jt Open 2023;4(6):424–431

Opinion remains divided as to whether the development of pathological fracture affects the prognosis of patients with an osteosarcoma of the extremities. We conducted a comprehensive systematic review and meta-analysis of papers which reported the outcomes of osteosarcoma patients with and without a pathological fracture. There were eight eligible papers for final analysis which reported on 1713 patients, of whom 303 (17.7%) had a pathological fracture. The mean age for 1464 patients in six studies was 23.2 years old (2 to 82). The mean follow-up for 1481 patients in seven studies was 90.1 months (6 to 240). The pooled estimates of local recurrence rates in osteosarcoma patients with and without pathological fractures were 14.4% (8.7 to 20.0) versus 11.4% (8.0 to 14.8). The pooled estimate of relative risk was 1.39 (0.89 to 2.20). The pooled estimates of five-year event-free survival rates in osteosarcoma patients with and without a pathological fracture were 49.3% (95% CI 43.6 to 54.9) versus 66.8% (95% CI 60.7 to 72.8). The pooled estimate of relative risk was 1.33 (1.12 to 1.59). There was no significant difference in the rate of local recurrence between patients who were treated by amputation or limb salvage. The development of a pathological fracture is a negative prognostic indicator in osteosarcoma and is associated with a reduced five-year event-free survival and a possibly higher rate of local recurrence. Our findings suggest that there is no absolute indication for amputation, as similar rates of local recurrence can be achieved in patients who are carefully selected for limb salvage. .

Pathological fractures in children can occur as a result of a variety of conditions, ranging from metabolic diseases and infection to tumours. Fractures through benign and malignant bone tumours should be recognised and managed appropriately by the treating orthopaedic surgeon. The most common benign bone tumours that cause pathological fractures in children are unicameral bone cysts, aneurysmal bone cysts, non-ossifying fibromas and fibrous dysplasia. Although pathological fractures through a primary bone malignancy are rare, these should be recognised quickly in order to achieve better outcomes. A thorough history, physical examination and review of plain radiographs are crucial to determine the cause and guide treatment. In most benign cases the fracture will heal and the lesion can be addressed at the time of the fracture, or after the fracture is healed. A step-wise and multidisciplinary approach is necessary in caring for paediatric patients with malignancies. Pathological fractures do not have to be treated by amputation; these fractures can heal and limb salvage can be performed when indicated

Aims. The aim of this paper was to investigate the prognostic factors for local recurrence in patients with pathological fracture through giant cell tumours of bone (GCTB). Patients and Methods. A total of 107 patients presenting with fractures through GCTB treated at our institution (Royal Orthopaedic Hospital, Birmingham, United Kingdom) between 1995 and 2016 were retrospectively studied. Of these patients, 57 were female (53%) and 50 were male (47%).The mean age at diagnosis was 33 years (14 to 86). A univariate analysis was performed, followed by multivariate analysis to identify risk factors based on the treatment and clinical characteristics. Results. The initial surgical treatment was curettage with or without adjuvants in 55 patients (51%), en bloc resection with or without reconstruction in 45 patients (42%), and neoadjuvant denosumab, followed by resection (n = 3, 3%) or curettage (n = 4, 4%). The choice of treatment depended on tumour location, Campanacci tumour staging, intra-articular involvement, and fracture displacement. Neoadjuvant denosumab was used only in fractures through Campanacci stage 3 tumours. Local recurrence occurred in 28 patients (25%). Surgery more than six weeks after the fracture did not affect the risk of recurrence in any of the groups. In Campanacci stage 3 tumours not treated with denosumab, en bloc resection had lower local recurrences (13%), compared with curettage (39%). In tumours classified as Campanacci 2, intralesional curettage and en bloc resections had similar recurrence rates (21% and 24%, respectively). After univariate analysis, the type of surgical intervention, location, and the use of denosumab were independent factors predicting local recurrence. Further surgery was required 33% more often after intralesional curettage in comparison with resections (mean 1.59, 0 to 5 vs 1.06, 0 to 3 operations). All patients treated with denosumab followed by intralesional curettage developed local recurrence. Conclusion. In patients with pathological fractures through GCTB not treated with denosumab, en bloc resection offers lower risks of local recurrence in tumours classified as Campanacci stage 3. Curettage or resections are both similar options in terms of the risk of local recurrence for tumours classified as Campanacci stage 2. The benefits of denosumab followed by intralesional curettage in these patients still remains unclear

Aims. The aim of this study was to validate the Mirels score in predicting pathological fractures in metastatic disease of the lower limb. Patients and Methods. A total of 62 patients with confirmed metastatic disease met the inclusion criteria. Of the 62 patients, 32 were female and 30 were male. The mean age of patients was 65 years (35 to 89). The primary malignancy originated from the breast in 27 (44%) patients, prostate in 15 (24%) patients, kidney in seven (11%), and lung in four (6%) of patients. One patient (2%) had metastatic carcinoma from the lacrimal gland, two patients (3%) had multiple myeloma, one patient (2%) had lymphoma of bone, and five patients (8%) had metastatic carcinoma of unknown primary. Plain radiographs at the time of initial presentation were scored using Mirels system by the four authors. The radiographic components of the score (anatomical site, size, and radiographic appearance) were scored two weeks apart. Inter- and intraobserver reliability were calculated with Fleiss’ kappa test. Bland-Altman plots were created to compare the variances of the individual components of the score and the total Mirels score. Results. Kappa values for the interobserver variability of the components of the Mirels score were k = 0.554 (95% CI 0.483 to 0.626) for site, k = 0.342 (95% CI 0.285 to 0.400) for size, k = 0.443 (95% CI 0.387 to 0.499) for radiographic appearance, and k = 0.294 (95% CI 0.258 to 0.331)for the total score. Kappa values for the intra-observer reliability were k = 0.608 (95% CI 0.506 to 0.710) for site, k = 0.579 (95% CI 0.487 to 0.670) for size, k = 0.614 (95% CI 0.522 to 0.703) for radiographic appearance, and k = 0.323 (95% CI 0.266 to 0.379) for total score. Conclusion. Our study showed fair to moderate agreement between authors when using the Mirels score, and moderate to substantial agreement when authors rescored radiographs. The Mirels score is subjective and lacks reproducibility in predicting the risk of pathological fracture. Cite this article: Bone Joint J 2018;100-B:1100–5

Aims. The aim of this study was to assess the current trends in the estimation of survival and the preferred forms of treatment of pathological fractures among national and international general and oncological orthopaedic surgeons, and to explore whether improvements in the management of these patients could be identified in this way. Materials and Methods. All members of the Dutch Orthopaedic Society (DOS) and the European Musculoskeletal Oncology Society (EMSOS) were invited to complete a web-based questionnaire containing 12 cases. Results. A total of 96 of 948 members of the DOS (10.1%; groups 1 and 2) and 33 of 182 members of the EMSOS (18%; group 3) replied. The estimation of survival was accurate by more than 50% of all three groups, if the expected survival was short (< 3 months) or long (> 12 months). General orthopaedic surgeons preferred using an intramedullary nail for fractures of the humerus and femur, irrespective of the expected survival or the origin of primary tumour or the location of the fracture. Oncological orthopaedic surgeons recommended prosthetic reconstruction in patients with a long expected survival. Conclusion. Identifying patients who require centralized care, as opposed to those who can be adequately treated in a regional centre, can improve the management of patients with pathological fractures. This differentiation should be based on the expected survival, the type and extent of the tumour, and the location of the fracture. Cite this article: Bone Joint J 2018;100-B:1392–8

Introduction: Mirels scoring system is a recognised method of assessing the risk of fracture in metastatic bone disease (MBD) based on radiological and clinical risk factors. Although reproducible, there are overlaps in the outcome of the scores. Aim: The aim of this study is look at the association between the tumour volume and ratio, and the incidence of pathological fracture. Method: Mirels score was calculated retrospectively from the patient notes. X-rays were scanned and analysed using the IMAGICA program. All tumours were measured twice on two views to the closest 0.1mm. The average of the two readings were used for the final calculations. Tumour volume was measured using 3 axis readings on the anteroposterior (AP) and lateral views of the tumour. The AP and lateral width of the tumour and the long bone shaft was measured to obtain the AP and Lateral Tumour Ratio (APTR and LTR respectively). Results: 58 patients were admitted in 2003 with suspected primary or MBD of a long bone. 50 patients were included. 28(56%) were male. Average age was 69.2years (range 10–98years). 6(12%) patients had a lytic lesion with no fracture and 18(36%) with pathological fracture. We were unable to measure Mirels score due to poor documentation. Patients with lytic lesion and no fracture had lower APTR and LTR, 0.88 and 0.85 respectively compare with the patients with lytic fractures (APTR 0.98 and LTR 0.91). This trend was not seen in tumours with sclerotic and mixed features. The average tumour volume was higher in the patients with lytic lesion and associated fracture than those with no fracture, 27.3 and 20.7cm³. 17(85%) of the lytic lesions, with volume larger than 10 cm³ had pathological fracture. Conclusion: The fracture rate is higher in presence of larger tumour with higher AP and lateral tumour ratio. A single measurement of the tumour volume may be more appropriate in the assessment of a lytic lesion for pathological fracture

Case Report: Metastatic deposits in the proximal femur commonly result in pathological fracture. Conventionally these fractures are treated surgically, by internal fixation or arthroplasty. The emphasis in treating these fractures is on restoring stability to the proximal femur and relieving pain. We present two cases in which pathological fractures of the proximal femur secondary to metastatic renal carcinoma were treated conservatively with excellent functional outcomes. In both cases, the medical condition of the patient precluded surgery. A 68 year old male with a subcapital fracture of the proximal femur was treated with bedrest and mobilisation. At 6 months he was able to mobilise with crutches, swim, and had returned to almost all normal activities despite non-union of the fracture. A 63 year old male had a pathological fracture of the proximal femur treated by DCS fixation. The fracture failed to unite and the plate fractured. Despite this the patient was able to walk with crutches, pain free. Discussion: After a pathological fracture of the proximal femur conservative management can lead to satisfactory analgesia, function and therefore quality of life

We investigated whether the presence of a pathological fracture increased the risk of local recurrence in patients with a giant cell tumour (GCT) of bone. We also assessed if curettage is still an appropriate form of treatment in the presence of a pathological fracture. We conducted a comprehensive review and meta-analysis of papers which reported outcomes in patients with a GCT with and without a pathological fracture at presentation. We computed the odds ratio (OR) of local recurrence in those with and without a pathological fracture. . We selected 19 eligible papers for final analysis. This included 3215 patients, of whom 580 (18.0%) had a pathological fracture. The pooled OR for local recurrence between patients with and without a pathological fracture was 1.05 (95% confidence interval (CI) 0.66 to 1.67, p = 0.854). Amongst the subgroup of patients who were treated with curettage, the pooled OR for local recurrence was 1.23 (95% CI 0.75 to 2.01, p = 0.417). . A post hoc sample size calculation showed adequate power for both comparisons. . There is no difference in local recurrence rates between patients who have a GCT of bone with and without a pathological fracture at the time of presentation. The presence of a pathological fracture should not preclude the decision to perform curettage as carefully selected patients who undergo curettage can have similar outcomes in terms of local recurrence to those without such a fracture.

Aim of presentation: We present a case of patellar metastasis from lung carcinoma resulting in pathological fracture. Material and methods: A 66 years old man with a clinical diagnosis of carcinoma of lung presented with complaints of severe pain in his right knee after a minor injury. Radiograph revealed undisplaced fracture of patella through a lytic area. A fine needle biopsy was done which showed infiltration of bone by non-small cell carcinoma consistent with origin in lung. Patient was treated conservatively in a splint and received local radiotherapy for pain relief. The fracture healed clinically and radiologically in six weeks time inspite of increase in the size of tumour on x-rays. Conclusion: Patella is a rare site of metastasis. Mercury et al reviewed the literature from 1900 to 2000 and reported about 15 cases of patellar metastasis from lung carcinoma. Pathological fractures are even rare. This case is presented as a rare case of pathological fracture of patella

We reviewed the treatment and clinical outcome of 32 consecutive patients with Ewing’s sarcoma who presented with or developed pathological fracture after biopsy between 1984 and 2004. The minimum follow-up was 18 months. The mean age at diagnosis was 20 years (5 – 51). There were 18 males and 14 females. All patients were newly diagnosed and had localized disease at the time of diagnosis. 21 patients presented with pathological fracture while 11 patients developed fracture during the course of chemotherapy. The femur was the most common location in 15 patients. All the patients had chemotherapy according to the protocol current at the time of treatment. 6 patients had radiotherapy alone while 26 patients underwent surgical excision and reconstruction. Of the patients who had surgery, 7 patients had adjuvant radiotherapy. Fracture healing was the norm after pre-operative chemotherapy. Surgical margins were wide in 17 patients, marginal in 4 and intralesional in 3 patients. Local recurrence developed in one patient (3%). Metastases occurred in 12 patients (37%). At the time of review 16 patients were free of disease, 3 were alive with disease and 13 patients had died of disease. The cumulative 5 year metastases free and overall survival in all the patients was 58% and 61 % respectively and similar to patients with Ewing’s sarcoma without fracture treated at our centre. The prognosis of patients who presented with fracture was exactly similar to those who developed fracture in the course of treatment. We conclude that limb preserving surgery is perfectly safe in patients with Ewing’s sarcoma who have associated pathological fracture and survival is not in any way compromised. Survival of patients who present with fracture is similar to those who develop fracture in the course of treatment. The exact role of adjuvant radiotherapy in these patients needs to be clarified

Introduction: Metastases in multiple myeloma are typically lytic and when non-union occurs it is usually atrophic. Methods: We report a lady of 67 years who was diagnosed with myeloma 9 years previously. She presented with a sudden onset of pain in her right forearm. Plain radiographs demonstrated a lytic lesion typical of multiple myeloma with an undisplaced pathological fracture in her right ulna. The fracture was treated in a short arm cast for 6 weeks and then by mobilisation. The underlying bone deposit was treated subsequently by external beam irradiation. Results: Nine months later she was re-referred to the orthopaedic oncology service with marked forearm pain particularly on rotation. Radiographs demonstrated a hypertrophic non-union of the pathological fracture with a typical elephant’s hoof appearance. The fracture was stabilised using a Foresight ulnar nail (Smith and Nephew, Warwick, UK). Discussion: Whilst non-unions in metastatic malignancy are typically atrophic, just occasionally hypertrophic non-unions can occur. Management principles remain the same with stabilisation of the entire bone and early mobilisation being appropriate

Large benign lytic lesions of the proximal femur present a significant risk of pathological fractures. We report our experience of treating 9 consecutive patients with such defects treated with curettage and fibula strut grafting without supplementary osteosynthesis to evaluate the outcome of this type of reconstruction. The mean age at the time of diagnosis was 13 years (8–21). Follow up ranged from 2 to 215 months (median 15). Histological diagnosis was fibrous dysplasia in 10 patients and unicameral cyst in 2. All the patients were at risk of pathological fracture. None of the patients developed pathological fracture after surgery and the lesions consolidated fully within one year. Local recurrence occurred in one patient (8%). Minor donor site complications occurred four patients. All the patients were able to fully weight usually within 3 months of surgery. At the time of review all but one patient were completely asymptomatic and fully weight bearing. The only symptomatic patient was the patient with local recurrence which has recently been treated. We conclude that fibula strut graft is a good method of reconstruction of cystic defects in the proximal femut. It prevents pathological fracture, allows mechanical reinforcement of the lesion and delivers biological tissue allowing early consolidation of the defect

Bone loss secondary to primary or metastatic lesions of the proximal humerus remains a challenging surgical problem. Options include preservation of the joint with stabilisation using internal fixation or resection of the tumour with prosthetic replacement. Resection of the proximal humerus often includes the greater tuberosity and adjacent diaphysis, which may result in poor function secondary to loss of the rotator cuff and/or deltoid function. Preservation of the joint with internal fixation may reduce the time in hospital and peri-operative morbidity compared with joint replacement, and result in a better functional outcome. We included 32 patients with pathological fractures of the proximal humerus in this study. Functional and radiological assessments were performed. At a mean follow-up of 17.6 months (8 to 61) there was no radiological evidence of failure of fixation. The mean revised musculoskeletal Tumour Society functional score was 94.6% (86% to 99%). There was recurrent tumour requiring further surgery in four patients (12.5%). Of the 22 patients who were employed prior to presentation all returned to work without restrictions. The use of a locking plate combined with augmentation with cement extends the indications for salvage of the proximal humerus with good function in patients with pathological and impending pathological fractures

Introduction: Estimates suggest that 50% of new cases of invasive cancer diagnosed each year will eventually metastasise to bone. The proximal end of the femur is the most common site of long bone involvement by metastatic disease. Accepted principles for the treatment of metastatic disease of the proximal femur have been published. The results of 31 consecutive patients treated with a long intramedullary hip screw for metastatic disease of the proximal femur are reported. Patients and Methods: Retrospective case note review of all patients that had a long intramedullary hip screw for metastatic disease affecting the proximal femur over a four-year period 1998–2002. Results: The case notes of 31 patients (33 femurs) were reviewed. There were 21 females and 12 males with a mean age of 71 years. 31 femurs were Zickel group Ia or Ib, the remaining 2 were impending pathological fractures (Zickel group II) that were fixed prophylactically. Post operatively all patients were allowed to fully weight bear. 70 % of patients regained their initial level of mobility or increased their level of dependence by a factor of one. Mean hospital stay was 20.8 days (mode 7 days). Patients that died post operatively had a mean survival of 299 days (range 2–1034). Those patients that were still alive at the last follow up had a mean survival of 475 days (range 7–1384). There were no cases of fixation or implant failure. There was one case of deep infection that was treated by implant removal. Conclusion: On the basis of these findings, the long intramedullary hip screw fulfils the principles for treatment of metastatic disease and can be recommended for the treatment of pathological or impending pathological fractures of the proximal femur

Introduction: Pathological fracture of the clavicle is not such a rare condition. By definition the fracture occurs either without or with minimal trauma. We present a case of pathological fracture where there was a definite history of trauma; clouding the true malignant diagnosis. Case Report: A 73 year old man first presented to the Accident & Emergency Dept. of our hospital with a history of having fallen on to his left shoulder after throwing a piece of concrete, and to have developed swelling and pain around the shoulder immediately following the fall. On examination the main findings were swelling and bony tenderness over the proximal clavicle and inability to use his left shoulder due to pain. X-ray showed a fracture at the junction between the proximal 1/3 and distal 2/3 of the left clavicle, and he was given a broad arm sling for support and a one week appointment for review in the fracture clinic. Two clinic appointments later he was still complaining of pain. X-rays taken at that time showed what appeared to be some evidence of callus formation at the fracture site. Six weeks later he had clinical and radiological signs of what appeared to be “huge callus formation”. He was given a 3 month appointment for what was expected to be a final review. Before his next fracture clinic appointment, however, he became jaundiced and complained about this to his GP who felt it was obstructive jaundice and referred him to the physicians who admitted him to the hospital, and began to investigate him as to the cause of the jaundice. These investigations included an Ultrasound Scan of the abdomen which showed a bulky head of pancreas with biliary and pancreatic ductal dilatation; and a CT scan of the upper abdomen which showed the presence of a cystic mass within the caudate lobe of the liver. Soft tissue vascular encasement around the portal vein and hepatic artery were reported as in keeping with malignant infiltration. Extensive tumour was present within the retroperitoneum involving local vascular structures. He came down to the fracture clinic for his next clinic appointment from the ward. At this point he was very ill, deeply jaundiced and frail. The swelling of the clavicle was the size of a large orange, firm to touch with dilated veins. X-ray at this point showed complete radiological destruction of the medial 1/3 of the left clavicle. At this point palliative care was the mainstay of his management. A week later the chest x-ray report came back as showing collapse of the left upper lobe with whiteout appearance and bulky hilum indicating an underlying bronchogenic carcinoma. Three days later, almost 5 months after initial presentation following a fall, this patient finally succumbed to his disease. Conclusion: This patient presented with a simple fracture and was given the standard treatment for the condition. However because his treatment was compartmentalized, i.e., orthopaedics treating the orthopaedic condition, radiology doing x-rays, and physicians managing the jaundice; it took some months before the different pieces of the jig-saw puzzle were put together and the malignant diagnosis arrived at

Eleven patients with metastases in the cervical spine had operations for severe pain due to a pathological fracture which, in eight of the cases, was unstable. Conservative treatment had either failed or was unsuitable. In the first five patients internal fixation with tension band wires and bone grafts was supported by a halo-brace. The method has evolved to the use of posterior instrumentation with laminar wires from two levels above the lesion to two levels below. Stability is increased by the use of bone cement with or without bone autografts applied to one side of the spine. This technique enables the patient to get up within a few days of operation--a great advantage when life expectancy is limited. The operations were successful in all except one case

Purpose: The purpose of this study was to determine factors predictive of tumour recurrence, or refracture, following curettage as treatment for pathological fracture of the proximal humerus through a benign bone lesion. Methods: From a cohort of patients held on a national database the factors predictive of recurrence following surgical curettage in patients with pathological fractures through benign bone tumours of the proximal humerus were examined. Thirty nine cases were identified. The diagnosis was simple bone cyst in 27 patients (69.2%), aneurysmal bone cyst in 4 patients (10.3%), (en)chondroma in 4 patients (10.3%), giant cell tumour in 2 patients (5.1%), benign chondroblastoma in 1 patient (2.6%) and fibroma in 1 patient (2.6%). The mean age was 16.5 years and 70% were male. Results: Most of the patients presented with a history of trauma (77%). Five patients were excluded as their fractures were not treated with surgical curettage. Twenty two patients (65%) had recurrence of the lesion or re-fracture following curettage. None of the patients in whom the fracture occurred after skeletal maturity had a recurrence. Obliteration of the lesion occurred more frequently in those with greatest initial fracture displacement on pre-operative radiographs and in those with impacted fractures. The average time to union and obliteration of the lesion was 4 months (range 1 to 13 months). Conclusions: Factors predictive of recurrence following curettage were age under 21 years, undisplaced fractures and fractures without impaction on initial radiographs. Patients with these features should be followed up until obliteration of the lesion or skeletal maturity
