Abstract
CASE We present a proximal femoral central physeal bar secondary to femoral neck fracture management, in a 3-year-old boy. He presented with progressive femoral neck deformity and limb length discrepancy. He was managed with a novel technique of bar resection by drilling and polymethylmethacrylate interposition. After 5 years of follow-up, the hip score by Ratliff criteria was good. CONCLUSION Screw penetration across physis during management of femoral neck fracture can cause growth arrest in a young child. Our technique is useful when physeal bar is central and linear. It can allow sufficient growth and remodeling to restore a near-normal hip both radiologically and clinically.

Abstract
The purpose of this study was to analyze the outcomes of titanium elastic nail (TEN) for the children in 6 to 10 years old who sustained a Delbet IV femoral neck fracture.A total of 56 children aged 6 to 10 years old with Delbet IV femoral neck fracture treated with TEN or cannulated screw (SC) were identified at our hospital from January 2009 to December 2019. Of which 24 were treated with TEN, and 32 with SC. All of them were followed up for 1 year after operation, and the differences in operation time, intraoperative blood loss, hospitalization time, hip joint function, and complication between the 2 groups were compared. Harris and Ratliff hip score were used to evaluate the hip function.All 56 fractures united properly. No major complications were noted in both groups. The intraoperative blood loss and operation time in TEN group and SC group were (11.42 ± 3.41) mL, (19.66 ± 4.05) mL (P = .000) and (33.58 ± 7.89) min, (40.22 ± 7.48) min (P = .002), respectively. There was no significant statistical difference between hip regarding range of motion and femoral neck-shaft angle in both groups, as well as Harris and Ratliff hip score between the 2 groups.TEN represent safe and effective methods in the treatment of Delbet IV femoral neck fracture in 6 to 10 years old children. TEN internal fixation is a minimal invasive and simpler technique and suitable for young children of Delbet IV femoral neck fracture.

The clinical features, management options and complications of paediatric femoral fractures. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 31:883-892.

Abstract
This article discusses the incidence, applied anatomy and classification of paediatric femoral fractures based on critical appraisal of the available evidence. The aim is to identify techniques that are relevant to contemporary practice whilst excluding the technical details of individual procedures that are beyond the scope of this review. Injuries of the proximal, diaphyseal and distal segments are considered individually as there are considerations that are specific to each anatomical site. Femoral neck fractures are rare injuries and require prompt anatomical reduction and stable fixation to minimise the potentially devastating consequences of avascular necrosis. Diaphyseal fractures are relatively common, and there is a spectrum of management options that depend on patient age and size. Distal femoral fractures often involve the physis, which contributes up to 70% of femoral length. Growth arrest is common consequence of fractures in this region, resulting in angular and length-related deformity. Long-term surveillance is recommended to identify deformity in evolution and provide an opportunity for early intervention. Deliberate injury should be considered in all fractures, particularly distal femoral physeal injuries and fractures in the non-walking child.

Abstract
BACKGROUND Femoral neck fractures in children are rare injuries, occurring due to high-energy trauma. Due to the unique anatomy and blood supply of the proximal femur in growing children, these fractures are notorious for high rates of complications despite appropriate management. Classification of these fractures is according to the Delbet system, which not only guides management but also gives prognostic clues. Multiple fixation methods have been described and there is no consensus on what constitutes the best treatment. Osteonecrosis, non-union, coxa vara and premature physeal arrest are the most frequent complications. PURPOSE To review the current knowledge, discuss controversial aspects, and provide suggestions for future research. METHODS We have reviewed the literature on paediatric proximal femur fractures and have provided an evidence-based guide to the diagnosis and management of these injuries. Common complications have been elaborated and options for their prevention and/or management discussed. CONCLUSION There is universal agreement that anatomic reduction and stable internal fixation, supplemented by spica immobilization in younger children, are essential to obtain good outcomes. The role of capsular decompression, choice and configuration of implant, and appropriate timing of surgery are aspects that continue to be debated. Multicenter prospective studies are necessary to standardize treatment of these challenging injuries.

Abstract
BACKGROUND Proximal femoral physeal fractures are rare in abused children. Recognition may be hampered due to their rarity and lack of an ossified femoral head. Prompt diagnosis and treatment are essential to preventing coxa vara. OBJECTIVE To demonstrate the radiographic features of proximal femoral physeal fractures both with unossified and ossified femoral heads. MATERIALS AND METHODS We reviewed our Institutional Review Board-approved 21-year radiology database of 2,206 children who had a skeletal survey as part of their medical evaluation for possible abuse. Cases of proximal femoral physeal fractures were identified. RESULTS Eight patients, ages 2.5 to 26 months, with 10 fractures were found, yielding a prevalence of 0.4% (8/2,206). In all fractures, there was lateral displacement of the proximal femur. In three fractures, the femoral head was not ossified, simulating a hip dislocation. The intra-articular location of the femoral head was verified by ultrasound or abdomen computed tomography. Subperiosteal new bone formation was present in six fractures, all non-weight-bearing patients. The femoral head was ossified in seven cases, all with medial rotation of the femoral head. Metaphyseal irregularity was present in three of four fractures of the weight-bearing patients; two of three also had metaphyseal scalloping resembling osteomyelitis. The three with metaphyseal irregularity developed coxa vara. CONCLUSION Proximal femoral physeal fractures are rare in abuse cases. All present with lateral displacement of the proximal femur. With an unossified femoral head, it can simulate hip dislocation, which can be clarified with hip sonogram. Metaphyseal irregularity appears to be a feature in weight-bearing patients.

Abstract
We present a rare case of a previously healthy 16-year-old boy who sustained simultaneous bilateral femoral neck fractures after a single first-time seizure episode. He was diagnosed to have severe vitamin D deficiency and secondary hyperparathyroidism. Symptomatic hypocalcemia was the cause of seizures. Both fractures were treated surgically and united at 3 months. Bilateral femoral neck fractures after seizures are very rare, especially in children. Severe vitamin D deficiency may cause seizures and also weakening of bone, predisposing to fractures without significant trauma. We recommend that paediatric cases of femoral neck fractures after seizures should be investigated for underlying metabolic disease.

Abstract
Pediatric hip fractures are uncommon injuries but are associated with a high complication rate including avascular necrosis, coxa vara, nonunion, and premature physeal arrest. This is due in part to the unique anatomy of the proximal femur. Management principles are aimed at minimizing the risk of complications and emphasize the importance of early treatment with anatomic reduction and stable internal fixation with a low threshold for supplementing fixation with a spica cast. The age of the patient and Delbet fracture type dictate the optimal type of fixation for a given case. This article will offer evidence and experience-based tips intended to benefit on-call surgeons caring for these injuries.

Abstract
PURPOSE To develop and evaluate the reliability of an explicit set of parameters and criteria for simple bone cysts (SBCs) and evaluate the reliability of single versus serial chronological reading methods. METHODS Radiographic criteria were developed based on the literature and expert consensus. A single anteroposterior/lateral radiograph from 32 subjects with SBC were evaluated by three radiologists. A second reading was then conducted using revised criteria including a visual schematic. In the third reading the same images were assessed but radiologists had access to images from two additional time points. Inter-rater reliability was assessed after each reading using kappa (κ) and percentage agreement for categorical and binary parameters and intra-class correlation coefficient (ICC) for continuous parameters. RESULTS Parameters that were revised with more explicit definitions including the visual schematic demonstrated consistent or improved inter-rater reliability with the exception of continuous cortical rim present and cyst location in the metaphysis and mid-diaphysis. Cortical rim displayed only slight reliability throughout (κ= -0.008 to 0.16). All other categorical parameters had a percentage agreement above 0.8 or a moderate (κ= 0.41 to 0.60), substantial (κ = 0.61 to 0.80) or almost perfect inter-rater reliability (κ = 0.81 to 1.0) in at least one reading. All continuous parameters demonstrated excellent inter-rater reliability (ICC > 0.75) in at least one reading with the exception of scalloping (ICC = 0.37 to 0.70). Inter-rater reliability values did not indicate an obviously superior method of assessment between single and serial chronological readings. CONCLUSION Explicit criteria for SBC parameters used in their assessment demonstrated improved and substantial inter-rater reliability. Inter-rater reliability did not differ between single and serial chronological readings. LEVEL OF EVIDENCE Not Applicable.

Abstract
In the pediatric population, femoral neck fracture is a relatively uncommon injury with a high complication rate, despite appropriate diagnosis and management. The anatomy and blood supply of the proximal femur in the skeletally immature patient differs from that in the adult patient. Generally, these fractures result from high-energy trauma and are categorized using the Delbet classification system. This system both guides management and aids the clinician in determining the risk of osteonecrosis after these fractures. Other complications include physeal arrest, coxa vara, and nonunion. Multiple fracture fixation methods have been used, with the overall goal being anatomic reduction with stable fixation. Insufficiency fractures of the femoral neck, although rare, must also be considered in the differential diagnosis for the pediatric patient presenting with atraumatic hip pain.

Abstract
PURPOSE Several therapeutic strategies have been used for managing unicameral bone cyst (UBC) of the proximal femur. However, there is insufficient evidence to support one treatment over another, and the optimal treatment is controversial. This study aims at describing our experience with surgical reconstruction of paediatric UBCs of the proximal femur using a proximal locking plate and fibular strut allograft. METHODS In total, 14 consecutive paediatric patients with Dormans types IB (four cases) and IIB (10 cases) UBC were assessed. Mean patient age was 8.6 ± 2.3 years, and mean follow-up period was 41.7 ± 29.8 months. Six patients (42.8%) were referred with a pathologic fracture. Clinical/radiological outcome and complication rates were evaluated at the final follow-up session. RESULTS No cysts were Capanna's class III (recurrence) or IV (no response). Complete healing (Capanna's class I) was seen in ten cysts, while four other cysts healed with residual radiolucent areas (Capanna's class II). Mean healing period was 14.1 ± 5.1 (9-24 months). One patient had superficial infection, one heterotopic ossification, and one mild coxa vara, and mean Musculoskeletal Tumor Society (MSTS) score was 99.5%. CONCLUSION According to our results, locking plate and fibular strut graft in Dormans classification types IB and IIB results in a favorable outcome in managing UBC of the proximal femur in the paediatric population.

Abstract
CONTEXT Hip fracture registries offer an opportunity to identify and to monitor patients with rare conditions and outcomes, including hip fractures in pediatric patients. OBJECTIVE To report patient demographics and surgical outcomes of pediatric patients treated surgically for hip fractures in a large integrated health care system. DESIGN Pediatric patients (< 21 years old at the time of fracture) with hip fractures were identified between 2009 and 2012 using our health care system's hip fracture registry. MAIN OUTCOME MEASURES Patient characteristics, type of fracture, surgical treatment, and short-term complications. RESULTS Among 39 patients identified, 31 (79.5%) were male, and the median age was 15 years old (interquartile range: 11-17 years). Most patients were Hispanic (n = 17, 43.6%) or white (n = 14, 35.9%). There were 8 patients (20.5%) with 15 comorbidities. Delbet Type IV (intertrochanteric) fractures were the most common fracture type (n = 22, 56.4%), and fixation method was equally distributed between intramedullary, screw and sideplate, and screws (n = 12, 30.8% for each). Most surgeries were performed by medium-volume surgeons (n = 22, 56.4%) at medium- and high-volume hospitals (n = 37, 94.9%). Three 90-day readmissions (7.7%), 1 infection (2.6%), 1 malunion (2.6%), and 1 revision (2.6%) were observed in this cohort during the study period. CONCLUSION In our series using registry data, hip fractures younger than age 21 years were more common in boys and Hispanic patients. Intertrochanteric fractures (Delbet Type IV) were the most frequently observed type in our community-based hip fracture registry. Short-term complications were infrequent.

Abstract
Lower extremity injuries are slightly less common than upper extremity injuries in children, and the structures below the knee are more often involved. Impaction injuries are often associated with twisting forces which can result in subtle buckle and hairline types of fractures, particularly in young children. Epiphyseal-metaphyseal injuries are especially common at the ankle. A variety of avulsion fractures also occur in the lower extremities, often associated with injury to nearby cartilaginous and ligamentous structures. This article reviews the important plain radiograph findings of lower extremity injuries in children as well as indications for special imaging such as ultrasound and MRI.

Abstract
OBJECTIVES Fractures of the proximal femur account for less than 1% of all children's fractures. Because of this, most orthopaedic surgeons lack enough experience in treating them. This adds to the rather high incidence of complications especially nonunion. At the time of this review there is no consensus on which method of treatment of the nonunion is the best. The objective of this study is to present our method of treatment to correct the nonunion without open reduction of the nonunion sites. METHOD 9 children with nonunion of the proximal femur with an average age of 10.2 years (2-14 years old) were included in the study. There were 7 males and 2 females. All of them underwent at least 1 operation to treat the initial fractures and the nonunion. The nonunion in all these 9 cases was treated with valgus intertrochanteric osteotomy without open reduction of the nonunion site. The healing time of the nonunion, the postoperative neck-shaft angle and the functional outcome were evaluated. RESULTS All the nonunion cases had coxa vara and had bone resorption of the femoral neck with x-ray evidences of avascular necrosis (AVN). Ratliff classification was used to classify the AVN, Ratliff type 3 was found in 4 cases, Ratliff 2 in 1 case and Ratliff 1 in 4 cases. Patients were followed for an average of 68 (range 36-156) months. All patients had x-ray evidence of solid union of the nonunion in an average time of 15.4 (range 13-18) weeks and union of the osteotomy sites within10.6 (range 9-12) weeks. The postoperative neck-shaft angle averaged 135° (range 125°-150°) compared to 98° before the surgery. The increase in the amount of neck-shaft angle was statistically significant (p<0.001). Using Harris Hip Score, 2 patients were graded as excellent, 3 patients were graded as good and 4 patients were graded as fair. Harris Hip Score was significantly improved compared to the preoperative status (p<0.001). CONCLUSIONS Nonunion paediatric femoral neck fracture treatment could be successfully treated without open reduction by using valgus intertrochanteric osteotomy. All patients obtained union of the nonunion site and the osteotomy site in this study. Harris Hip Score showed significant improvement. This technique can be used to treat nonunion with associated coxa vara, bone resorption and AVN with satisfactory results even in cases who had received several operations before.

Abstract
A femoral neck stress fracture in child is rare, particularly in bilateral case. It is easy to miss initially or may be misdiagnosed. The authors experienced a case of bilateral femoral neck stress fracture in a 10-year-old boy with bilateral hip. The patient was successfully healed by conservative treatment. We report this rare case with a review of the literature. A femoral neck stress fracture should be included in the differential diagnosis in children who present with sustained hip or groin pain.

Abstract
BACKGROUND The most serious complication of femoral neck fractures in children and adolescents is osteonecrosis. Although a number of factors have been implicated in the development of osteonecrosis, no specific cause-and-effect relationship has been determined. The primary purpose of this study was to determine the prevalence of osteonecrosis in children and adolescents after femoral neck fractures and to identify risk factors for its development. METHODS This retrospective review identified 70 patients between the ages of 1.3 and 18.1 years who were treated for a femoral neck fracture between 2000 and 2011 at a single level I pediatric trauma center and followed until clinical and radiographic union. Demographic information, injury event details, type of surgical treatment, associated injuries, time from injury to treatment, and postoperative alignment were recorded from chart and radiographic review. The primary outcome was the presence of osteonecrosis, which was determined by review of available imaging. Multivariable logistic regression analysis tested age, time to treatment, type of fixation, mechanism of injury, postoperative alignment, and capsular decompression as possible risk factors for the development of osteonecrosis. RESULTS Osteonecrosis occurred in 20 (29%) of the 70 patients. The median time to diagnosis of osteonecrosis was 7.8 months. Multivariable predictors of osteonecrosis included fracture displacement (P=0.01) and fracture location (P=0.02). Patient age, type of fixation, mechanism of injury, capsular decompression, postoperative alignment, and performance of reduction were not predictive of osteonecrosis after femoral neck fracture. Finally, time to treatment also was found to be a positive predictor of osteonecrosis (P=0.004), with osteonecrosis more likely in patients treated in less than 24 hours, but this finding is likely due to confounding because injury severity was closely linked to time to treatment. CONCLUSIONS Regardless of the treatment, the prevalence of osteonecrosis after femoral neck fractures remains high. Recognizing factors that are predictive of the development of osteonecrosis can help surgeons counsel patients and families appropriately about the risk of this complication.

Abstract
Peripubertal boys with autism spectrum disorder (ASD) have lower bone mineral density (BMD) than typically developing controls. However, it is not clear whether lower BMD in ASD results in an increased fracture rate. This study examined the rate of fractures in children and adults with and without ASD using a national database of emergency room visits (Nationwide Emergency Department Sample). A higher odds ratio for hip fractures in children and young adults (3-22 years) as well as older adults (23-50 years) with ASD than those without ASD, and a higher odds ratio for forearm and spine fractures in women ages 23-50 with ASD were found. Further studies are necessary to better understand the decreased bone density in ASD and its implications for fracture development.

Abstract
INTRODUCTION Fractured neck of femur in osteogenesis imperfecta is rarely reported. Its management is always difficult because of bone fragility and the outcome is not well known. We, therefore, aimed to study the management pitfalls in this group of patients. METHODS We retrospectively reviewed five cases of fractured neck of femur in four patients treated in our hospital between 2006 and 2009. The demographic data, mode of injury, fracture configuration, treatment, complications, clinical and radiological outcome were reviewed. RESULTS According to the Sillence classification, one patient was type I, two were type III and one was type IV. There were two children (aged 8 and 15 years) and two adults (aged 21 and 22 years), with the 8 year-old girl suffering from hip fracture on different sides in two accidents. All five hip fractures were the result of low-energy injury and were associated with other fractures. Two undisplaced fractures required intra-operative fluoroscopic confirmation to demonstrate movement at the fracture site. The interval between the injury and fixation ranged from 6 h to 3 days. One hip required secondary surgery to openly reduce the fracture due to inadequate primary fixation and reduction. Two hips were fixed with paediatric dynamic hip screws and three hips were fixed with cannulated screws. All patients were immobilised in hip spica for 6 weeks. The average follow-up was 4 years (3-5 years). All patients had satisfactory union and none of them developed radiological evidence of avascular necrosis at the latest follow-up. All patients returned to their pre-injury functional level. CONCLUSION Fractured neck of femur is rare given the high prevalence of long bone fractures in osteogenesis imperfecta. They all have characteristic associated fractures of the extremity at the time of injury and neck of femur fractures could be easily missed. Fracture fixation is a great challenge to the orthopaedic surgeons because of the small size of the patients, poor bone quality with suboptimal imaging intra-operatively and compromised purchase of fixation devices. The choice of implants should be determined by the size of the patients and the presence of prior instrumentation close to the hip joint.

Abstract
A 7-year-old boy developed complaints of pain in the left groin. These complaints started spontaneously. Initial plain radiographs of the pelvis indicated no abnormalities. As the symptoms persisted for 6 weeks, the young patient and his parents visited our institution. Clinical investigation showed a slight extension deficit of the left hip. New radiographs and MRI indicated a fracture line with sclerosis along the inferior border of the left femoral neck. In retrospect, this stress fracture of the femoral neck was also visible on the initial radiographs. Seven months after the onset of complaints in the left groin and prescribed partial weight bearing with crutches, callus formation with consolidation of the femoral neck was observed on radiographs. Eleven months after onset, the patient recovered fully without any residual symptoms. After 21 months, the young patient did not have any complaints or restrictions in physical activity. Because of its highly rare nature, stress fractures of the femoral neck in children are easy to miss initially. This was also applicable in our case. Extensive differential diagnosis of a child with pain in the groin furthermore adds to the difficulty in the diagnosis of a stress fracture of the femoral neck. This case report emphasizes the importance of the evaluation of radiographs and observation in children with hip complaints. Similarly, interdisciplinary consultation and cooperation between the general practitioner, orthopaedic surgeon, radiologist and paediatrician is essential in the diagnosis, evaluation and treatment of these young patients.

Abstract
This report presents a case demonstrating the nonunion of a capital femoral physeal fracture with a large metaphyseal fragment in a 10-year-old boy. To our knowledge, there is no previously reported case of this type of nonunion. The treatment of this nonunion presented a potential risk of premature physeal closure and avascular necrosis of the femoral head, so internal fixation using cannulated screws and percutaneously drilling with a Kirschner wire to the metaphyseal fragment was used and was effective in bone union without these complications.

Abstract
OBJECTIVE Optimal reposition and stable fixation of M/1 and M/2 fractures are necessary. Careful operation and urgent surgery prevent complications. INDICATIONS M/1 and M/2 fractures of the proximal femur in children > 4 years. CONTRAINDICATIONS E/1 fractures are fixed with Kirschner wires. M/3 fractures are fixed with elastic stable intramedullary nailing. Fractures up to the age of 4 are fixed with Kirschner wires. SURGICAL TECHNIQUE Surgical approach via a lateral incision. Anatomic fixation of the fracture with two to three cannulated screws. POSTOPERATIVE MANAGEMENT No weight bearing during the first 4-6 weeks. Physiotherapy is optional. Magnetic resonance imaging at least 1 year after the fracture or immediately in case of problems to control the vascular situation of the femoral head. RESULTS Due to the rarity of these fractures, only few results from large series have been published. M/1 fractures show a higher complication rate than M/2 fractures. The risk of avascular necrosis has to be estimated at up to 40%.

Abstract
Transepiphyseal separation of the neck of the femur following grand mal seizures is described in two children with cerebral palsy. Closed reduction and percutaneous fixation was followed by a period in a hip spica. Although the incidence of avascular necrosis of the femoral head is high following such injury, this has not occurred in these patients at a follow-up of 18 months.

Abstract
OBJECTIVES To evaluate the role of a modified Pauwels' intertrochanteric osteotomy (MPIO) in neglected femoral neck fractures in children. DESIGN Prospective study with retrospective analysis. SETTING Tertiary care Postgraduate Institute of Medical Sciences. PATIENTS Ten children (8 males, 2 females) with an average age of 10.2 years with neglected femoral neck fractures were seen from 1990 to 1998. A femoral neck fracture was considered neglected when no proper medical treatment was instituted for at least 1 month following the fracture. Nonunion was accompanied by coxa vara and resorption of the femoral neck in 9 patients; a 10th patient had a neglected femoral neck fracture for 1 month without coxa vara. Three patients at time of presentation with Delbet Type II displaced fractures with associated nonunion and coxa vara (2 with Ratliff Type III and 1 with Type I) also had avascular necrosis using plain radiographic criteria of increased density. INTERVENTION Modified Pauwels' intertrochanteric osteotomy. The children were immobilized in a hip spica for 6-10 weeks postoperatively and weightbearing was started after hip spica removal. MAIN OUTCOME MEASUREMENTS Fracture healing, neck-shaft angle, avascular necrosis, and functional outcome. RESULTS Patients were followed for an average of 8.2 years (range 5-12 years). All patients had union of their fracture within an average of 16.6 weeks (12-20 weeks) and of the osteotomy site within 8.2 weeks (7-9 weeks). Radiologic signs of avascular necrosis disappeared completely in the 3 patients who presented with avascular necrosis. In 1 patient with a preoperatively viable femoral head, radiologic signs of Ratliff Type I avascular necrosis appeared between 60 and 98 weeks. This radiologic finding became normal again, indicating viability of the femoral head somewhere between 98 to 205 weeks of follow-up. Postoperatively, an average of 135-degree neck-shaft angle was achieved (range 125-160 degrees). The average preoperative neck-shaft angle was 104.4 degrees (range 92-120 degrees) and on the normal hip side it was 127.7 degrees (range 124-132 degrees). Significant improvement in the neck-shaft angle was seen compared with the preoperative angle (P < 0.001) and normal hip angle (P < 0.05). Coxa vara and signs of chondrolysis were not observed in any of the patients. Premature proximal femoral epiphyseal closure resulting in a 1-cm and a 1.5-cm leg-length discrepancy was seen in 2 patients as compared with their normal side. A mild Trendelenburg gait was observed in 1 patient (10%). Using Ratliff's criteria, 9 patients (90%) were graded as a good result and 1 patient (10%) was graded as a fair result. The osteotomy plate was removed in 1 patient (10%). CONCLUSION An MPIO creates a biomechanical environment conducive to healing of a neglected femoral neck nonunion in a child while simultaneously correcting an associated coxa vara. The procedure also seems to have a biological role in helping restore viability to a noncollapsed femoral head with avascular necrosis.

Abstract
Fractures of the hip are uncommon in children, and their importance is related not to the frequency of the injury but to the frequency of complications. Many of these complications can be minimized or avoided by anatomic reduction and internal fixation. Open reduction frequently is necessary to obtain a stable, anatomic reduction. Regardless of the age of the child, stable fixation of the fracture must be given priority over preservation of the proximal femoral physis. The development of osteonecrosis, however, is most likely related to the severity of the initial injury and is largely unaffected by treatment of the fracture.

Abstract
Twenty-six children and adolescents with displaced femoral neck fractures who were treated surgically from 1992 to 2002 were included in this study. Among them, 14 were male and 12 were female. Altogether, 10 of them had a transcervical type of fracture, and the other 16 had a cervicotrochanteric type of fracture. The average age of the patients was 10.8 years (3-17 years). Seventeen were treated by closed reduction and internal fixation (group A), and nine required open reduction and internal fixation (group B). In group A, there were good results in 11 cases (65%), a fair result in one case (6%), and poor results in 5 cases (29%). In group B, there were good results in seven cases (78%) and fair results in the other two cases (22%). The average fracture union times in groups A and B were 12.6 and 10.2 weeks, respectively. Thus, there was a favorable outcome in group B. However, statistical analysis of data in this preliminary study did not reveal any significant difference in the surgical outcome between the two groups.

Abstract
Fractures through bone tumors are often difficult to treat. We reviewed our combined experience with this problem in children, as well as the existing literature, to formulate management guidelines. For this study, prospective databases (1987 to 2002) from three referral centers were screened for pathologic fractures occurring under the age of 14 years. One hundred five patients presented with fracture through unicameral bone cyst, nonossifying fibroma, fibrous dysplasia, aneurysmal bone cyst and osteosarcoma. Seventeen patients were excluded. The most common primary locations were the proximal humerus and proximal femur. Pathologic fracture through nonossifying fibroma had the best outcome; union occurred with nonsurgical treatment in all cases. Unicameral bone cyst required surgical treatment to avoid persistence of the cyst and refracture. However fracture healing was predictable without surgical treatment. Proximal femoral lesions tended to heal in malunion if not fixed surgically. Aneurysmal bone cyst required surgical treatment for the lesion to heal and to allow the fracture to heal as well. Percutaneous sclerotherapy may be the treatment of choice for many of these lesions. Fibrous dysplasia allows fracture healing with nonoperative therapy. Progressive deformity requires followup and surgical correction. Malignant lesions presenting a pathologic fracture are best managed by initial nonoperative therapy during investigation and neoadjuvant therapy when possible, followed by definitive treatment.

Abstract
In this retrospective study, we evaluated the characteristics of 103 femoral neck fractures in 102 children seen our department between 1978 and 1994. In order to evaluate the correlation between the chosen procedure and complication risks, we further reviewed the late treatment results of 62 fractures in 61 children of the series whom we had followed for a minimum of 8 years. The ages of these children at the time of injury ranged from 2 to 14 years (average 10.2 years). Sixty-three hips were available for clinical and radiographic follow-up at a minimum of 8 years (mean 14 years). Overall, 67.2% radiologically good results were obtained. Complications were coxa vara in five (8%), avascular necrosis in nine (14.5%), premature epiphysis fusion in five (8%), coxa valga in two (3.2%), non-union in one (1.6%), limb shortening in seven (11.3%), and arthritic changes in two (3.2%). Our long-term follow-up revealed that the type of treatment influences the complication rate more than do the characteristics of the fracture itself, and that the end result cannot be satisfactorily determined until after physeal closure.

Abstract
The Orthopaedics Unit of Aseer Central Hospital, Abha, Saudi Arabia became fully operational in 1992. From then till 1999, 14 cases of fractures of the neck of femur in children under the age of 16 years were studied. The aims of the study were to compare our experience with those of other institutions and to serve as a reference point in this region for future study of this rare but disabling condition. The case notes of all the patients aged less than 16 years with fractures of the neck of femur managed at the Aseer Central Hospital between 1992 and 1999 were analysed retrospectively. Information obtained included age, sex, type of fracture, management, outcomes and complications. There were 14 children. The age range between 4 and 16 years (mean = 9.1 +/- 3.8 years). Male to female ratio was 1:1.3. Eight cases (57.1%) were due to road traffic crashes and 6 (42.9%) were due to falls from height. Six cases (42.9%) were of Delbet type II (transcervical) fractures, 5 cases (35.7%) were of type III (cervicotrochanteric), and 3 cases (21.4%) were of type IV (intertrochanteric) fractures. There was no case of Delbet type I (transepiphyseal separation). Patients were treated either surgically by reduction and internal fixation or conservatively by traction followed by hip spica cast application. Avascular necrosis occurred in 7 cases (50.0%). Only 3 cases of partial avascular necrosis were seen and all the 3 improved. The rest 4 (28.6%) had collapse of the femoral head. In only 2 cases (14.3%) of femoral neck fracture, the patients did not have any associated injuries. While fracture of neck of the femur is rare in children, the high incidence of complications that can lead to life-long disability makes it an important clinical entity.

Abstract
This is a long-term study of 53 children with fracture of the proximal femur. The age of these children at the time of injury ranged from 3 to 16 years (average, 10.2 years). The follow-up period averaged 9.4 years (range, 5-20 years). There was a single transepiphyseal fracture, 28 transcervical fractures, 21 basicervical fractures and three intertrochanteric fractures. The overall results were good in 49, fair in 25 and poor in 26% of patients. Better results were obtained in undisplaced fractures and in those displaced fractures where anatomical reduction was achieved and maintained throughout fracture healing. The rate of early and delayed complications was 60%, with some patients having more than one complication. Avascular necrosis occurred in 40%. It was found to be related to initial fracture displacement and was associated was an inferior outcome. Other complications included coxa vara in 36, non-union in 36, premature physeal closure in 38, shortening in 55, arthritic changes in 34, coxa valga in 9, coxa magna in 2, and post-operative infection in 23% of patients. The quality of reduction appeared to influence the occurrence of some complications such as avascular necrosis and non-union.
