Li T, Dai Z, Ma Q, Zhou H, Li H, Zhang Z. Surgical outcomes of proximal femoral bone cysts in pediatric patients: a retrospective study of 41 cases. Front Pediatr 2024; 12:1331089. [PMID: 38978837 PMCID: PMC11228295 DOI: 10.3389/fped.2024.1331089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 06/12/2024] [Indexed: 07/10/2024] Open
Abstract
Purpose The aim of this study was to evaluate the surgical outcomes of proximal femoral bone cysts in pediatric patients. Methods We retrospectively analyzed 41 pediatric patients (31 males and 10 females, mean age 7.47 ± 2.67 years, range 2.03-14.67 years) diagnosed with proximal femoral bone cysts treated at a single institute between March 2009 and November 2021. Data included demographics, preoperative details, intraoperative conditions, surgical techniques, postoperative outcomes, recurrence, and complications. Results Of the participants, 68% presented with simple bone cysts and 32% with aneurysmal bone cysts. Prior to surgery, 32% exhibited pathological fractures. Surgical methods included lesion curettage, defect filling using allograft bone and Minimally-Invasive Injectable Graft ×3, and varied fixation techniques. Postoperative recurrence (17%) was associated with cyst location between the capital femoral epiphysis and the linea intertrochanterica (P = 0.010). At the final assessment (mean follow-up: 26.51 ± 18.99 months), all showed radiological bony union with 93% rated as "good" and 7% as 'fair' based on Ratliff hip scores. Complications arose in 20% of patients, significantly correlated with prior pathological fractures (P = 0.007) and their association with the linea intertrochanterica (P = 0.004). Those with fractures reported higher intraoperative blood loss (P = 0.015) and longer surgery durations (P = 0.012) compared to those without. Conclusion Treating pediatric proximal femoral bone cysts using techniques such as lesion curettage, defect filling, and selective internal fixation yields favorable outcomes. The presence of pathological fractures can prolong surgical time, increase intraoperative blood loss, and elevate postoperative complication risks. Hence, early surgical intervention for these cysts is recommended to prevent fractures.

Abstract
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.

Abstract
INTRODUCTION Most tumour-related pathological fractures occur in patients with bone metastases. However, in mostly younger patients, a pathological fracture can be due to both a benign or a malignant bone tumour. Making the correct diagnosis from among these two differential diagnoses is enormously important. If the tumour is malignant, treating the fracture inevitably leads to tumour cell contamination and can significantly worsen the oncological situation. The aim of this review article is firstly to provide the reader with diagnostic assistance in the case of suspected pathological fractures, and secondly to focus on the treatment of pathological fractures occurring with benign bone tumours. METHODS This is a non-systematic review of the diagnosis and treatment of pathological fractures in benign bone tumours or tumour-like lesions, based on an electronic PubMed database search. We also present our own procedures, in particular for ruling out a malignant bone tumour. RESULTS AND DISCUSSION Whenever a fracture occurs in the absence of sufficient traumatic force, the possibility of a pathological fracture should always be considered. As well as taking a general history for a possible primary tumour, it is particularly important to ask the patient whether they had any pain before the fracture occurred. If the findings from clinical examination or conventional radiological imaging give rise to suspicion of a pathological fracture, an MRI of the affected skeletal section with contrast medium should be carried out before commencing any fracture treatment. A CT scan is also helpful for accurately assessing bone destruction. If a malignant or locally aggressive benign bone tumour such as giant cell tumour (GCT) or aneurysmal bone cyst (ABC) cannot be definitively ruled out through imaging, a biopsy is essential. The bone biopsy must always be carried out on the assumption that the histological work-up will reveal a malignant bone tumour; it must therefore be performed according to strict oncological criteria. If the radiological diagnosis is unambiguous, e. g., a juvenile bone cyst (JBC) or a non-ossifying fibroma (NOF), conservative treatment of the fracture can be considered, depending on the location. In the presence of a locally aggressive benign bone tumour such as a GCT or ABC, curettage of the tumour must be carried out as well as treating the fracture. With GCT in particular, neoadjuvant therapy with denosumab prior to curettage and osteosynthesis or en bloc resection of the tumour should be considered, depending on the extent of the tumour. CONCLUSION Pathological fractures, especially in younger patients, should not be overlooked. Only after a malignant or benign locally aggressive bone tumour has been definitively ruled out should fracture treatment be performed. In the presence of a locally aggressive bone tumour, as well as treating the fracture, it is usually necessary to perform curettage of the tumour - also en bloc resection, where applicable, in the case of a GCT. Depending on the location, benign, non-aggressive tumours can be treated conservatively if necessary.

Abstract
Fractures around the shoulder girdle in children are mainly caused by sports accidents. The clavicle and the proximal humerus are most commonly involved. Both the clavicle and the proximal humerus have a remarkable potential for remodeling, which is why most of these fractures in children can be treated conservatively. However, the key is to understand when a child benefits from surgical management. Clear indications for surgery of these fractures are lacking. This review focuses on the available evidence on the management of clavicle and proximal humerus fractures in children. The only strict indications for surgery for diaphyseal clavicle fractures in children are open fractures, tenting of the skin with necrosis, associated neurovascular injury, or a floating shoulder. There is no evidence to argue for surgery of displaced clavicle fractures to prevent malunion since most malunions are asymptomatic. In the rare case of a symptomatic malunion of the clavicle in children, corrective osteosynthesis is a viable treatment option. For proximal humerus fractures in children, treatment is dictated by the patient's age (and thus remodeling potential) and the amount of fracture displacement. Under ten years of age, even severely displaced fractures can be treated conservatively. From the age of 13 and onwards, surgery has better outcomes for severely displaced (Neer types III and IV) fractures. Between 10 and 13 years of age, the indications for surgical treatment are less clear, with varying cut-off values of angulation (30-60 degrees) or displacement (1/3 - 2/3 shaft width) in the current literature.

Abstract
BACKGROUND The proximal femur is a common location for pathologic fractures in children, yet there is little published information regarding this injury. The purpose of this study was to investigate the outcomes of pediatric pathologic proximal femur fractures due to benign bone tumors. METHODS A retrospective review of patients treated for pathologic proximal femur fractures from 2004 to 2018 was conducted. Inclusion criteria were age below 18 years and pathologic proximal femur fracture secondary to a benign bone tumor. Patients were excluded if they had <1 year of follow-up. Medical charts and serial radiographs were reviewed for fracture classification, underlying pathology, treatment, complications, and time to fracture healing. RESULTS A total of 14 patients were included. Mean age was 6±3 (3 to 11) years, and mean follow-up was 44±21 (22 to 86) months. Index treatment was spica casting in 9/14 (68%) patients, while 5/14 (32%) were treated with internal fixation. Of the 9 patients initially treated with casting, 22% (2/9) required repeat spica casting at a mean of 0.6 months after index treatment, 67% (6/9) required internal fixation at a mean of 20.3 months after index treatment, and 11% (1/9) did not require revision treatment. Eighty-eight percent (8/9) of patients treated with casting required revision treatment compared with 40% (2/5) of those treated with internal fixation (P=0.05). Nonunion occurred after 1 refracture, malunion with coxa vara occurred in 2 fractures, and the remaining 11/14 (84%) fractures had a union at a mean of 4.9±3.0 months All cases of malunion occurred in patients initially treated nonoperatively. There were 19 distinct complications in 10/14 (71%) patients. The incidence of any revision surgery was 64% (9/14). CONCLUSIONS In this series, pediatric pathologic proximal femur fractures demonstrated prolonged time to union, high incidence of revision surgery (64%), and substantial complication rate (71%). In children with pathologic proximal femur fractures, treatment with internal fixation is recommended as this series showed a 78% failure rate of initial conservative management. LEVEL OF EVIDENCE Level IV.

Abstract
PURPOSE Benign lesions of the proximal femur region, such as simple bone cysts, aneurysmal bone cysts, and fibrous dysplasia, are common in children. Benign lesions may cause pathologic fractures, limb length inequities, and growth disturbances. Differential diagnoses, e.g., malignant bone tumors and osteomyelitis, are sometimes difficult to rule out. OBJECTIVE We aimed to evaluate outcomes in children with benign lesions of the proximal femur treated with curettage, bone grafting, and plate fixation. METHODS In this retrospective study, we included 30 children (median age 10.5 years; range 1.1-17.8 years) suffering from bone cysts and tumor-like lesions of the proximal femur region treated between 2002 and 2018. We analyzed plain X-ray images and CT scans in all children and obtained MRI scans in a selected group of children (63.3%). We examined histopathologic biopsy results for all bone lesions before initiating treatment. Surgical management comprised tumor curettage with adjuvant high-speed drilling and allogenic bone grafting supplemented by bone graft substitutes before plate fixation. Median follow-up interval was 87 months (range 24-156 months). We evaluated the healing of lesions according to Capanna's classification and rated functional outcomes according to Merle d'Aubigné and Postel score. RESULTS Overall, 25 of 30 (83.3%) patients were admitted to hospital because of a pathologic fracture. We diagnosed simple bone cysts in 15 (50.0%) patients, aneurysmal bone cysts in 7 (23.5%) patients, and fibrous dysplasia in 8 (26.5%) patients. Bone consolidation was achieved in 22 of 30 (73.3%) patients after a mean of 5 months (range 3-7 months). The main complication was recurrence of the lesion in 4 of 30 (13.3%) patients. With respect to the Merle d'Aubigné and Postel scores, 17 of 30 (56.7%) patients obtained an excellent result (18 points), while 12 (40.0%) patients had a good result (15-17 points) and only 1 (3.3%) patient had a fair result (14 points). CONCLUSION Surgical treatment of bone cysts and tumor-like lesions of the proximal femur by local resection or destruction of the lesion, followed by filling the defect with bone graft material and internal stabilization represents a safe and effective treatment option in children. LEVEL OF EVIDENCE Therapeutic, retrospective comparative study-Level III.

Abstract
PURPOSE OF REVIEW The purpose of this review is to review recent literature focusing on proximal humerus anatomy, epidemiology of these fractures, diagnosis and treatment options, and clinical outcomes. RECENT FINDINGS Non- or minimally displaced proximal humerus fractures treated nonoperatively do not lead to short- or long-term complication and do not cross over to operative treatment. There is a higher rate of operative management with older age, increased injury severity score, treatment at an adult hospital, and private insurance. Operative management is preferred with closed or open reduction and percutaneous pinning, but elastic nailing and plate fixation are other options with good postoperative outcomes. Pediatric proximal humerus fractures occur after fall onto the affected shoulder or arm. Diagnosis is usually made with radiographs. Understanding the proximal humerus anatomy is critical to the proper management of these injuries to aid reduction and predict remodeling potential. There is considerable debate around the management of proximal humerus fractures in the pediatric population. Treatment is based on patient age, fracture displacement, and remodeling capacity. Nonoperative management is successful in younger patients or less displaced fractures, and operative management is usually considered in older patients with more displaced fractures.

Abstract
BACKGROUND Presentation of benign lesions with a pathological fracture may be confusing to general orthopedic surgeons regarding missing a fracture in a pathological bone, the need for special care for these lesions, and the potential for healing of these fractures. The objective of this work was to evaluate the clinical and radiological outcomes of the treatment of patients with stages 1 and 2 Enneking benign bone-tumors presented with pathological fractures. METHODS This retrospective study included 66 patients who presented with a pathological fracture through stage 1 or 2 Enneking benign bone lesions and were received at the emergency unit of the orthopedic department between 2014 and 2018. Demographic data and patient's evaluation were collected. Lesion-size (length, width, and depth) was calculated from the X-ray. Surgical intervention was planned in 28 patients. The indication for surgery was either fracture fixation or curettage of the lesion with or without augmentation. There were no repeated surgeries or local recurrences. The filling of the cavity was classified according to modified Neer's classification. RESULTS Sixty-six patients, 45 males, and 21 females were included. Forty-two affections were right while 24 were left. The mean age was 14.9 ± 8.6 (range, 3-40) years. The most common radiological diagnoses were simple bone-cysts 43.9% (n = 29), followed by non-ossifying fibroma 27.3% (n =18). The mean length of the lesions was 4.4 ± 2.6 (range, 1 - 12) cm, width was 1.6 ± 0.8 (range, 0.3- 4.5) cm, and depth was 1.8 ± 0.9 (range, 0.3 - 5) cm. The mean follow-up was 24.15 ± 18.7 months. Minor complications occurred in 7 patients (10.6%). Fifty-four out of 65 lesions (83%) showed either almost complete or partial filling of the lesions. There was no significant difference regarding the filling of the lesions according to the modified Neer's classification between those who were treated conservatively and those who underwent surgical intervention P-value = 0.783. CONCLUSION Careful diagnosis of a pathological fracture through stages 1 and 2 Enneking benign bone tumors is essential before initiating treatment. These fractures have good potential for bone healing and a low incidence of complications even with conservative treatment. Special surgical care of the lesion is not mandatory in all situations and should be individualized. LEVEL OF EVIDENCE Level III, retrospective.

Abstract
A suspicion of a proliferative bone lesion in a child seems to be a major diagnostic problem for clinicians. There are no diagnostic and treatment algorithms described in the literature and no reliable cohort epidemiological data. Our study was conducted among 289 paediatric patients (0–18 years old) with an initial diagnosis of a bone tumour or tumour-like lesion. The study comprised a retrospective epidemiological analysis, an assessment of the concordance of the initial diagnoses with the histopathological diagnoses and an analysis of the specific locations of the various bone lesions. The results obtained have made it possible to formulate the following conclusions. (1) The most common proliferative bone lesion in children is osteochondroma; also common are fibrous dysplasia, non-ossifying fibromas and bone cysts. (2) Verifying the initial diagnosis by means of biopsy is essential. (3) Osteochondromas are typically located in the metaphyses of long bones, fibrous dysplasia in the femur and skull, cyst-like lesions in the proximal humerus and non-osteochondral fibromas exclusively in the lower limbs. What could improve the quality of treatment for children with primary proliferative bone diseases is the establishment of centres of paediatric orthopaedic oncology skilled in early diagnosis and prompt management.

Abstract
OBJECTIVE To determine the incidence and causes of pathological fractures in paediatric bone tumours and tumour-like lesions, and to determine if they are predictive of benign lesions. METHODS AND MATERIALS Retrospective review of children with suspected bone tumours referred to a specialist musculoskeletal oncology service between September 2019 and August 2020. Data recorded included patient age and gender, lesion location, the presence of a pathological fracture on the initial plain radiograph, and the final diagnosis made either by image-guided biopsy/curettage or based on typical imaging features. RESULTS 231 patients were included with 233 lesions (138 males and 93 females with mean age 10.5 years, range 3 months-18 years). Final diagnosis was based on histology in 85 (36.5%) cases and imaging in 148 (63.5%) cases, 52 (22.3%) lesions classed as non-neoplastic, 139 (59.7%) as benign and 42 (18%) as malignant. Pathological fractures were seen in 41 cases (17.6%) at presentation, involving the humerus in 19 (46.3%), the femur in 14 (34.1%), the tibia in 3 (7.3%), the fibula and radius in two each (4.9%) and the second toe proximal phalanx in 1 (2.4%) (p < 0.001). The commonest underlying lesions included simple bone cyst (n = 17; 41.5%) and non-ossifying fibroma (n = 10; 24.4%). Only 4 cases (9.75%) were malignant, one case each of osteosarcoma, Ewing sarcoma, leukaemia and BCOR undifferentiated round cell sarcoma. Pathological fracture occurred in 27.7% of non-malignant lesions and 9.5% of malignant lesions, this difference being statistically significant (p < 0.001). CONCLUSION Pathological fractures were seen in 17.6% of paediatric bone tumours, tumour-like lesions, being significantly associated with humeral location and non-malignant diagnosis. ADVANCES IN KNOWLEDGE Demonstrates the frequency, location and underlying diagnosis of pathological fractures in paediatric bone tumour and tumour-like lesions.

Abstract
PURPOSE Fractures of the femoral shaft in children are common. The rates of bone growth and remodeling in children vary according to their ages, which affect their respective management. METHODS This paper evaluates the incidence and patterns of pediatric femoral shaft fracture and the current concepts of treatments available. RESULTS The type of fracture-closed or open; stable or unstable-needs to be taken into account. Child abuse should be suspected in fractures sustained by infants. For younger children, non-surgical management is preferred, which include Pavlik harness (< 6 months old) and early spica casting (6 months to 6 years old). Older children (> 6 years old) usually benefit from surgical treatments as outcomes of non-surgical alternatives are worse and are associated with prolonged recovery times. These operative measures for older children that are 6-12 years old include elastic stable intramedullary nailing and submuscular plating. Factors to be considered when devising an appropriate intervention include body mass, location of injury, and nature of fracture. For adolescent and skeletally mature teenagers (> 12 years old), rigid antegrade entry intramedullary fixation is indicated. In the event of open fractures or polytrauma, external fixation should be considered as a temporary treatment method for initial fracture stabilization. CONCLUSION An age-based and evidence-based algorithm has been proposed to guide surgeons in the process of evaluating an appropriate treatment.

Abstract
Pathological fracture of the proximal femur represents a challenging situation for orthopedic surgeons because of the high risk of non-union, varus union, and avascular necrosis (AVN) of the femoral head. This study aims to investigate the efficacy of ESINs for the treatment of proximal femoral fractures caused by simple bone cysts (SBCs).All the patients with a diagnosis of proximal femoral fracture secondary to SBC treated with ESINs combined with bone grafting between January 2008 and January 2018, were analyzed retrospectively.In all, 11 patients were included in the Double ESINs group (5.1 ± 0.8 years, 5 male, 6 female) and 27 patients were included in the Triple ESINs group (9.1 ± 2.1 years, 11 male, 16 female). There was no significant difference between the 2 groups concerning the patients demographic parameters, including sex and affected side. However, the age in the Double group was significantly younger than those in the Triple group (P < .001). All patients in both groups displayed excellent outcomes according to the Musculoskeletal Tumor Society Score (MSTS), and there was no significant difference between the 2 groups at a 12-month follow-up evaluation (P = .10). As for the Capanna classification (1 + 2), there was no significant difference between these 2 groups (P = .24). In the Triple ESINs group, 24 (88.9%) patients were categorized in Capanna 1 and 2, whereas all patients in Double ESINs were Capanna 1 and 2. Overall, the success rate was 92%.ESINs combined with bone grafting is a successful strategy for proximal femoral fractures caused by SBCs in the pediatric population.

Abstract
Objectives Aneurysmal bone cyst (ABC) is a benign but locally aggressive tumor. It has several challenging features. The aim of this study is to identify challenges in the diagnosis and treatment of ABC especially in patients with unusual features. Methods This retrospective study involved medical record review of primary ABC patients with one or more of the following features: unusual clinical presentation with a mass or a pathological fracture especially at an unusual age, rare locations, radiological findings suggesting other diagnoses especially sarcoma, and a nondiagnostic histopathology of biopsy samples. Results 25 patients (17 males and 8 females) were included. Most patients were either younger than 10 or older than 20 years. 10 patients presented with a mass or a pathological fracture. Unusual locations include the scapula, the olecranon, the hamate, the calcaneus, and the first metatarsal bone. Extension into the epiphysis occurred in 2 patients with proximal fibula and olecranon ABCs. Two separate synchronous cysts existed in the proximal epiphysis and middiaphysis of one humerus. Radiological imaging suggested other primary diagnoses in 8 patients. Core needle biopsy was diagnostic in only 2 of 7 patients. The main treatment was intralesional resection/curettage with bone grafting. Wide resection was performed in 4 patients. Recurrence rate was 28%. Recurrence risk factors included the following: age less than 10 years, male gender, and proximal femur location. Late recurrence occurred in 3/7 patients. One patient with asymptomatic radiological recurrence showed subsequent spontaneous resolution one year later. Conclusions This study presented multiple unusual features of ABC including: unusual age, rare locations, and nondiagnostic radiological and histopathological findings. These features can complicate the diagnosis and management. Given these features, especially with pathological fractures, a well-planned incision, the use of frozen section examination, and the application of either external fixation or plate osteosynthesis for fracture fixation can be recommended.

Abstract
Primary malignant bone tumors are uncommon and heterogeneous malignancies. This document is a guideline developed by the Spanish Group for Research on Sarcoma with the participation of different specialists involved in the diagnosis and treatment of bone sarcomas. The aim is to provide practical recommendations with the intention of helping in the clinical decision-making process. The diagnosis and treatment of bone tumors requires a multidisciplinary approach, involving as a minimum pathologists, radiologists, surgeons, and radiation and medical oncologists. Early referral to a specialist center could improve patients' survival. The multidisciplinary management of osteosarcoma, chondrosarcoma, chordoma, giant cell tumor of bone and other rare bone tumors is reviewed in this guideline. Ewing's sarcoma will be the focus of a separate guideline because of its specific biological, clinical and therapeutic features. Each statement has been accompanied by the level of evidence and grade of recommendation on the basis of the available data. Surgical excision is the mainstay of treatment of a localized bone tumor, with various techniques available depending on the histologic type, grade and location of the tumor. Chemotherapy plays an important role in some chemosensitive subtypes (such as high-grade osteosarcoma). In other subtypes, historically considered chemoresistant (such as chordoma or giant cell tumor of bone), new targeted therapies have emerged recently, with a very significant efficacy in the case of denosumab. Radiation therapy is usually necessary in the treatment of chordoma and sometimes of other bone tumors.

Abstract
PURPOSE We aimed to develop a surgical treatment strategy for benign bone lesions of the proximal femur based upon retrospective review of our data in 62 children. METHODS Sixty-two children [38 male, 24 female; median age 9 years (range 5-18 years)] with proximal femoral benign bone lesions were surgically treated between 2005 and 2013. Histopathological diagnoses were simple (31) or aneurysmal (27) bone cysts, and nonossifying fibromas (4). The pathological fracture rate was 77.4 %. Surgical treatment was determined due to four criteria, including patient's skeletal maturity, localization and initial diagnosis of lesion, and amount of bone loss in the femoral neck and lateral proximal femur. Surgical procedure consisted of biopsy, curettage, bone grafting, and internal fixation when required. The median follow-up was 45 months (range 25-89 months). RESULTS Complete clinical recovery was achieved in 56 (90.3 %) patients between 4 and 8 months postoperatively; full weight-bearing and mobilization, without pain and limping, was possible. The median preoperative and postoperative last follow-up Musculoskeletal Tumor Society (MSTS) scores were 13.3 % (range 10-23.3 %) and 96.6 % (range 90-100 %), respectively (p < 0.0001). The pathological fractures were healed in 10 weeks on average (range 8-12 weeks). Fifty-seven (92 %) patients demonstrated complete or significant partial radiographic healing between 5 and 7 months that maintained throughout follow-up. Local recurrence was not observed, and only 1 (1.6 %) patient required reoperation for partial cyst healing. There were 5 (8 %) complications, 1 (1.6 %) of which required reoperation. CONCLUSIONS This treatment strategy can provide good local control and excellent functional and radiological results in the management of benign bone lesions of the proximal femur in children.

Abstract
The definitive treatment of paediatric femoral diaphyseal fractures remains controversial. Modalities of treatment vary mostly according to age, with fracture pattern and site having a lesser impact. Current evidence is reflective of this variation with most evidence cited by the American Academy of Orthopedic Surgeons being level 4 or 5. The authors present a review of the most up-to-date evidence relating to the treatment of these fractures in each age group. In an attempt to clarify the current trends, we have produced an algorithm for decision-making based on the experience from our own tertiary referral level 1 major trauma centre.

Abstract
INTRODUCTION The outcome of pathological fracture due to large aggressive benign stage 3 Dormans and Flynn lesions [6] is often unsatisfactory and the rate of recurrence is high. No single technique has been considered safe and successful. Many Authors suggested curettage and bone grafting as the unique effective treatment in cases of large defect but, because of the invasive and complex nature of the operation (it needs a double-step procedure), it is not preferred. The purpose of this study is to examine the effectiveness of a minimally invasive treatment in one step through ESIN, curettage and packing with self-setting calcium phosphate cement. PATIENTS AND METHODS This is a retrospective study of 116 children admitted at the Division of Pediatric Orthopaedics Surgery of Santobono Children Hospital between 2006 and 2014 with a diagnosis of pathological fracture due to large aggressive ostheolytic benign lesions (stage 3 Dormans and Flynn). The size of bone loss was measured on the AP and ML radiographs and all the cysts with a caudo cranial extension from 5 to 8cm and with a medio lateral extension from 3 to 5cm were included. Mean time follow up 24 months was performed. RESULTS The three-in-one procedure was applied in all 116 patients. After two years of follow up, 113 patients were classified as healed and just 3 required 3 years to complete heal. No severe life threatening adverse effects or complications associated with the use of ESIN and injectable HA were recorded during the follow up period of 24-36 months. Fracture healing occurred in all cases within 4-6 weeks with adequate periosteal and endosteal callus formation. No second pathological fractures occurred in our series as well as no cysts reoccurred. Patients with humeral localizations showed a more rapid regain of muscular function and reestablishment of a complete range of motion. CONCLUSIONS The proposed three-in-one procedure has shown to be efficient, cost-effective, associated to high rates of definitive bone healing and low incidence of adverse effects.

Abstract
A fracture is defined as pathological when it arises in a bone tissue that has been modified and reshaped by a local or systemic pathological process. In children, pathological fractures can be secondary to several conditions, ranging from metabolic diseases to tumors, infections or neuromuscular pathologies. History, clinical examination and radiologic assessment are essential to making a diagnosis, to identifying the underlying cause and to planning the right treatment of a pathological fracture. Treatment must be tailored to both the fracture and the underlying cause. The objective of this work is to present the diagnostic approach and the course to follow when a child presents with a pathological fracture. The most common causes of pathological fractures, as well as their characteristics, will be described. Pathological fractures occurring in osteogenesis imperfecta and in abused children as well as stress fractures will not be discussed.

Abstract
PURPOSE Different treatment modalities have been utilized to treat unicameral bone cyst (UBC), but evidence has not been fully described to support one treatment over another and the optimal treatment is controversial. The aim of this quantitative systematic review was to assess the effectiveness of different UBC treatment modalities. METHODS We utilized Pubmed to isolate retrospective studies on patients with UBC who received any kind of treatment. The included studies needed to have a minimum sample size of 15 patients, and have provided data on radiographic healing outcome. RESULTS Sixty-two articles were selected for the meta-analysis from a total of 463 articles. The cumulative sample size was 3,211 patients with 3,217 UBC, and male to female ratio was 2.2:1. The summary or pool estimate of methylprednisolone acetate (MPA) injection resulted in a healing rate of (77.4 %) that was comparable to bone marrow injection (77.9 %). A higher healing rate was observed with MPA injection when inner wall disruption was performed. The pool estimate of bone marrow with demineralized bone matrix injection was high (98.7 %). UBC healing rate after surgical curettage was comparable whether autograft or allograft was utilized (90 %). UBC treatment with flexible intramedullary nails without curettage provided almost 100% healing rate, while continuous decompression with cannulated screws provided 89 % healing rate. Conservative treatment indicated a healing rate of 64.2, 95 % CI (26.7-101.8). CONCLUSIONS Active treatment for UBC provided variable healing rates and the outcomes were favorable relative to conservative treatment. Due to the heterogeneity of the studies and reporting bias, the interpretation of these findings should be handled with caution.

Abstract
Proximal humerus fractures are rare in paediatric traumatology. Metaphyseal fractures account for about 70% of cases and epiphyseal separation for the remaining 30%. The development and anatomy of the proximal humerus explain the various fracture types, displacements, and potential complications; and also help in interpreting the radiographic findings, most notably in young children. Physicians should be alert to the possibility of an underlying lesion or pathological fracture requiring appropriate diagnostic investigations, and they should consider child abuse in very young paediatric patients. Although the management of proximal humerus fractures remains controversial, the extraordinary remodelling potential of the proximal humerus in skeletally immature patients often allows non-operative treatment without prior reduction. When the displacement exceeds the remodelling potential suggested by the extent of impaction, angulation, and patient age, retrograde elastic stable intramedullary nailing (ESIN) provides effective stabilisation. As a result, the thoraco-brachial abduction cast is less often used, although this method remains a valid option. Retrograde ESIN must be performed by a surgeon who is thoroughly conversant with the fundamental underlying principles. Direct percutaneous pinning is a fall-back option when the surgeon's experience with ESIN is insufficient. Finally, open reduction is very rarely required and should be reserved for severely displaced fractures after failure of closed reduction. When these indications are followed, long-term outcomes are usually excellent, with prompt resumption of previous activities and a low rate of residual abnormalities.

Abstract
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.

Abstract
Unicameral bone cysts (UBCs) in children usually are asymptomatic. Most UBCs are discovered when a radiograph is performed on a child who has had accidental trauma to a limb. Symptomatic cysts typically present with pain, often the result of pathologic fracture through a large cyst or occult stress fracture within the thinned cortex around the cyst. Simple radiography is the best method for detecting such cysts, which typically are located within the long bone (femur, tibia, fibula, humerus), but can appear elsewhere. Cysts typically appear in the proximal metaphysis, but some involve the epiphysis and growth plate, thereby affecting bone growth. If clinically necessary to confirm the diagnosis, computed tomography or magnetic resonance imaging can delineate the cyst better or demonstrate an occult fracture. For the asymptomatic UBC, close follow-up is the recommended course of action. However, surgical intervention by corticosteroid or autogenous bone marrow injection or open curettage with bone grafting is recommended if the cyst is symptomatic, carries an increased risk for pathologic fracture (weight-bearing bone or dominant arm of a throwing athlete), or shows signs of an impending pathologic fracture. Clinical and radiographic follow-up is recommended after surgical intervention, because UBC recurrence after initial surgery is reported to occur in 18% to 88% of patients.

Abstract
BACKGROUND Osteomyelitis is a common pediatric musculoskeletal infection. This infection can weaken the normal bone structure, resulting in the risk of a pathologic fracture. The purpose of this study was to evaluate the risk factors for pathologic fracture in children with Staphylococcus aureus osteomyelitis. METHODS Seventeen children who were treated for a pathologic long-bone fracture secondary to Staphylococcus aureus osteomyelitis between January 2001 and January 2009 at a tertiary-care pediatric hospital were identified. These patients were compared with a control group consisting of forty-nine children with Staphylococcus aureus osteomyelitis without a fracture who were matched for age, sex, and methicillin susceptibility. A retrospective review of the clinical records, magnetic resonance imaging (MRI) studies, and microbiologic findings was performed. RESULTS Patients who developed a fracture presented with osteomyelitis at a mean age of 8.8 years (range, two to seventeen years). Fifteen of the seventeen patients had methicillin-resistant Staphylococcus aureus (MRSA) isolates, and two had methicillin-susceptible Staphylococcus aureus (MSSA). The mean time from disease onset to fracture was 72.1 days (range, twenty to 150 days). The duration of hospitalization, number of surgical procedures, duration of antibiotic treatment, and total number of complications differed significantly between the two groups. MRI studies at the time of admission demonstrated a significantly greater prevalence of subperiosteal abscess and greater circumferential size of such an abscess in the patients with a fracture. A sharp zone of abnormally diminished enhancement of the marrow was also more common in these patients. The USA300-0114 pulsotype was more commonly associated with an elevated likelihood of fracture. CONCLUSIONS Staphylococcus aureus osteomyelitis is a serious infection that may predispose children to pathologic fractures. Protected weight-bearing and activity restriction are recommended in children with Staphylococcus aureus osteomyelitis who have the risk factors demonstrated in this study.

Abstract
OBJECTIVE The aim of this paper is to evaluate the frequency of limb shortening in the course of solitary bone cyst treatment. The correlation between the mode of treatment as well as the occurrence of pathological fracture, cyst location, volume, and locularity were examined. MATERIALS AND METHODS A retrospective analysis was carried out on 135 patients where 80 underwent curettage and bone grafting and 55 were administered methylprednisolone injection with a mean time to follow-up of 12 years. RESULTS Based on clinical and radiological evaluation, limb shortening was found in ten patients when the data before and after treatment was compared. Limb shortening ranging from 1 to 5 cm during the course of the treatment was observed: six in humerus, two in femur, two in tibia. Those with epiphyseal changes, magnetic resonance imaging to evaluate the degree of growth plate damage was performed. Patients with and without limb shortening did not differ statistically regarding the applied method of treatment. The cyst volume was significantly larger in the group of patients with limb shortening when compared to the group of patients with no limb shortening. CONCLUSIONS In patients treated with curettage and bone grafting, the mode of treatment does not increase the frequency of occurrence of iatrogenic limb shortening. In patients with limb shortening, a statistically significant larger volume of the cyst was observed.

Abstract
Aneurysmal bone cysts are rare lesions that occur more commonly in the first and second decades of life. In children, a juxtaepiphyseal location is associated with increased risk of growth plate damage, skeletal deformity, and recurrence. Different treatments have been reported for the management of aneurysmal bone cysts, including surgical excision with or without adjuvants, intralesional injection of sclerosing agents, radiation therapy, cryotherapy, systemic calcitonin therapy, and selective arterial embolization. The authors present the case of a 5-year-old girl with a large aneurysmal bone cyst at the proximal femur, complicated by a pathologic fracture; treatment with two selective transcatheter arterial embolizations was curative.

Abstract
Ewing sarcoma (ES) is the second most frequent primary malignant bone cancer, following osteosarcoma. ES is a small round-cell tumor typically arising in the bones, rarely in soft tissues, of children and adolescents. We describe four children aged 3, 3.5, 9, and 9.5 years, who presented with two femur masses simultaneously (patient 1), a huge mediastinal mass (patient 2), an abdomino-mediastinal mass with dysphagia (patient 3), and a huge abdomino-pelvic mass (patient 4). Our patients were of younger age and had abnormal presentations that made initial diagnosis difficult, but also are representative of the different problems encountered in pediatric practice. Biopsy initially revealed round cell tumor and by immunohistochemistry, CD99 was positive, which confirmed the diagnosis of ES. Our patients were difficult to diagnosis.The patients were misdiagnosed initially, so there was a delay in diagnosis. Definitive diagnosis required use of various radiological imaging methods and immunohistochemistry.

Abstract
Fibrous dysplasia is a developmental anomaly of bone formation that accounts for approximately 7% of benign bone tumors. It exists in a monostotic or polyostotic form, commonly occurs in the proximal femur, and may require total hip arthroplasty (THA) for its management in a select group of patients. The results of THA in patients with this disorder is not known. Of the 27,543 primary THAs performed at our institution between 1969 and 2001, 10 were in patients with fibrous dysplasia (prevalence of 0.04%). Two other patients (2 hips) with the same diagnoses were referred after a failed primary THA. The study group comprised 7 men and 4 women (1 bilateral) with an average age at primary THA of 44 years (range, 23-66 years). Four patients had the monostotic form and 7 patients had the polyostotic form. A cemented stem was used in 7 hips and cementless stem in the rest (N=12). Average follow-up was 15.7 years (range, 2-30 years). Seven hips in 6 patients were revised for loosening of components at an average of 12.5 years, and 2 of these were re-revised for the same reason. Loosening of a cementless femoral component led to early revision in 3 hips. The surgical outcomes for patients with monostotic was better than those with polyostotic disease. Long-term fixation of the femoral component is of concern in patients with fibrous dysplasia. Total hip arthroplasty provided these patients with long-lasting pain relief and function despite the higher rate of complications at the time of surgery.

Abstract
PURPOSE To report the outcomes of continuous decompression using a cannulated ceramic pin for simple bone cysts (SBCs). METHODS Seven boys and 3 girls aged 7 to 16 (mean, 11) years with SBCs underwent curettage and continuous decompression using a cannulated ceramic pin. The pin was made of hydroxyapatite and tricalcium phosphate. The clinical course, radiological findings, and complications were retrospectively assessed. RESULTS The mean follow-up duration was 41 (range, 12-84) months. Five patients were evaluated as 'healed', 2 as 'healing with defect', one as 'persistent cyst', and 2 as 'recurrent cysts'. No peri-operative complications were encountered. One patient had a postoperative fracture at the pin insertion site. Seven patients had pain relief and good outcomes; 2 had a thin cortical rim and complained of occasional pain and their sports activities were restricted. CONCLUSION Decompression using a cannulated ceramic pin for SBCs is minimally invasive, highly osteoconductive, and does not require bone grafting or a second operation to remove the device.

Abstract
BACKGROUND Pathologic or spontaneous fractures are recognised causes of morbidity in children. There is a paucity of data on their aetiology and patterns in African children. METHODS A combined retrospective and prospective study of 47 children aged 15 and below with pathologic fractures of long bones seen from January 2000 to December 2006. The setting was the Orthopaedic and Traumatology department of the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. RESULTS A total of 47 patients with a mean age of 5.3 years +/- SD with pathologic fractures of 50 long bones were seen and treated. The most commonly affected bones were the femur (28%), tibia (28%) and humerus (26%). Chronic osteomyelitis following inadequately treated acute haematogenous osteomyelitis was the commonest cause of pathologic fractures (74.5%). The mean duration of fracture union was 6.8 +/- 2.3 months and the outcome was satisfactory in 91.4% of cases. CONCLUSIONS The aetiology of pathologic fractures in the African population is different from their causes in Caucasian children. Chronic osteomyelitis following inadequately treated acute haematogenous osteomyelitis continues to plague many children in our environment.

Abstract
STUDY DESIGN Resident's case problem. BACKGROUND Nonossifying fibroma (NOF) is the most common fibrous bone lesion in children. The lesion is usually asymptomatic, and rarely leads to pathological fractures. DIAGNOSIS We present the case of a 12-year-old boy who appeared to be normally developed but had a pathological insufficiency fracture associated with NOF in the distal femur. He was a member of a track athletics club and ran more than 5 km every day. Seven weeks prior to the initial evaluation he felt discomfort in the left distal thigh when running and felt pain upon knee flexion. The amount of discomfort increased gradually and he began to experience pain while running 4 weeks prior to his initial evaluation. At the time of the initial evaluation, he had tenderness over the distal thigh region and there was increased pain with weight bearing. Plain radiographs showed an irregular, well-defined cortical bone lesion, suggesting NOF, with vague increased density in the bone marrow across the femur and periosteal new bone, suggesting a fracture. Computed tomography confirmed a linear fracture with increased density across the femur leading to the cortical lesion. In the process of differential diagnosis osteosarcoma, or Ewing sarcoma, and bone/joint infection were ruled out using magnetic resonance imaging. The final diagnosis based upon the images and clinical course was pathological insufficiency fracture associated with NOF. The patient was treated with initial avoidance of weight bearing using 2 crutches for ambulation, followed by progressive weight bearing over a period of 5 weeks. Active range of motion of the knee joint was allowed. Three months after onset (5 weeks after the initial evaluation), the patient had normal gait without pain, whereupon the patient resumed his sport activities, beginning with jogging. DISCUSSION Although pathological fractures secondary to NOF in the femur are rare, NOF can cause pathological insufficiency fractures in athletes, even if the lesion is confined and small. The current case is a reminder of such a possibility. This case also provides a time course as a reference for the rehabilitation of patients in similar cases. LEVEL OF EVIDENCE Diagnosis, level 4.

Abstract
A 12-year-old girl was diagnosed with Hodgkin's lymphoma and underwent conventional cross-sectional imaging for initial staging. Chemotherapy was given according to standard pediatric protocols. At the end of therapy, an F-18 FDG PET/CT examination was performed to evaluate the therapeutic response. The scan demonstrated focal uptake of FDG in the right distal femur and residual lymphoma was taken into consideration. However, findings in the coregistered CT scan were consistent with nonossfiying fibroma, a common benign skeletal lesion. Combined PET/CT imaging can be helpful to identify benign bone lesions mimicking metastatic or residual disease in F-18 FDG PET as illustrated by this case.

Abstract
The management of pathological fractures in children remains controversial. The indications for surgical treatment are unclear and the need for histological diagnosis before or after definitive treatment is not clearly defined. We reviewed retrospectively the records of all patients under the age of 16 years who presented over the past 7 years with a fracture as the first manifestation of bone pathology. There were 23 patients (16 boys and 7 girls) of an average age of 12 years and 2 months (range 4.1-15.8 years). There were nine cases of fracture through a simple bone cyst, five cases of fibrous dysplasia, two giant cell tumours, three aneurysmal bone cysts, one chondroblastoma, and three cases of Ewings sarcoma. After review of our cases we propose a simple algorithm for the safe early management and assessment of paediatric pathological fractures. We recommend that primary fixation of pathological fractures should be avoided until histological diagnosis is obtained. Most lesions should eventually be biopsied. However, if radiographic appearances are reassuringly benign, biopsy can be delayed until conservative fracture management is completed. Definitive treatment of benign lesions with protective intra medullary nailing or curettage and grafting can follow frozen section under the same anaesthetic.

Abstract
The treatment of most extremity bone or soft tissue sarcomas involves either limb salvage surgery with adjuvant chemoradiation therapy or amputation. The rehabilitation of patients with extremity sarcomas is challenging, and the approach differs depending on the choice of surgical procedure as well as potential-associated medical complications. Early, interdisciplinary rehabilitation involvement is helpful in lessening the impact of expected impairments and disability. There is a lack of evidence examining specific rehabilitation interventions in this patient population. Functional outcomes and quality of life studies suggest overall similar findings between limb salvage patients and amputees, but with differences in various subscales. Rehabilitation interventions are therefore individualized; based on the assessment of medical limitations, functional goals and expectations, and modification of environmental factors. Overcoming medical and oncologic barriers to rehabilitation; as well as psychological, structural, cultural, political, and economic barriers; can serve to lessen the degree of disability.
