Abstract
Aims The aim of this study was to produce clinical consensus recommendations about the non-surgical treatment of children with Perthes' disease. The recommendations are intended to support clinical practice in a condition for which there is no robust evidence to guide optimal care. Methods A two-round, modified Delphi study was conducted online. An advisory group of children's orthopaedic specialists consisting of physiotherapists, surgeons, and clinical nurse specialists designed a survey. In the first round, participants also had the opportunity to suggest new statements. The survey included statements related to 'Exercises', 'Physical activity', 'Education/information sharing', 'Input from other services', and 'Monitoring assessments'. The survey was shared with clinicians who regularly treat children with Perthes' disease in the UK using clinically relevant specialist groups and social media. A predetermined threshold of ≥ 75% for consensus was used for recommendation, with a threshold of between 70% and 75% being considered as 'points to consider'. Results A total of 40 participants took part in the first round, of whom 31 completed the second round. A total of 87 statements were generated by the advisory group and included in the first round, at the end of which 31 achieved consensus and were removed from the survey, and an additional four statements were generated. A total of 60 statements were included in the second round and 45 achieved the threshold for consensus from both rounds, with three achieving the threshold for 'points to consider'. The recommendations predominantly included self-management, particularly relating to advice about exercise and education for children with Perthes' disease and their families. Conclusion Children's orthopaedic specialists have reached consensus on recommendations for non-surgical treatment in Perthes' disease. These statements will support decisions made in clinical practice and act as a foundation to support clinicians in the absence of robust evidence. The dissemination of these findings and the best way of delivering this care needs careful consideration, which we will continue to explore.

Abstract
INTRODUCTION Legg-Calve-Perthes disease (LCPD) is a disorder involving the hips in young children of preschool and school-going age groups, more common in 4-8 years. The insufficient blood supply to the femoral head is the main reason behind various etiologic theories. Multiple factors affect the natural progression of the disease. The natural progression of the disease involves early avascular necrosis, fragmentation, reconstitution, and healed stages. In the fragmentation stage, the bony epiphysis begins to fragment, and the subchondral radiolucent zone (crescent sign) is the result of a subchondral stress fracture, which later on determines the extent of a necrotic fragment of the femoral head. These changes later contribute to changes in the shape of the femur head and the extent of deformity. As vitamin D plays a vital role in the onset of the fragmentation stage, we conducted a study to assess the effect of vitamin D deficiency as a risk factor for early fragmentation in Legg-Calve-Perthes disease. METHODS In our study, 50 patients aged 4-12 years were examined over three years and classified according to Catterall and Herring's lateral pillar classification; the length of the fragmentation stage and the vitamin D level were considered. A vitamin D level of less than 20 ng/mL was labeled as the deficient group, 20-30 ng/mL as the insufficient group, and more than 30 ng/mL as the sufficient (normal) group. RESULTS The critical fragmentation stage was significantly longer (more than 12 months) in vitamin D deficiency (34%), leading to a higher risk of deformity and extrusion of the femoral head, which led to higher rates of surgical intervention and containment procedures. CONCLUSION The fragmentation stage is critical in the course of LCPD. Vitamin D levels play a vital role in predicting the prognostic of LCPD, and it should be measured in all patients of LCPD. Patients with normal vitamin D levels have a comparatively shorter fragmentation stage duration than patients with insufficient or deficient levels, leading to a lesser duration of femoral head damage.

Abstract
BACKGROUND Legg-Calve-Perthes disease (LCPD) in children older than seven years has often been associated with accelerated progress and poor outcome. The results of varus derotation osteotomy (VDRO) of the proximal femur in this cohort are not consistently predictable. This study was aimed at assessing the functional outcome of VDRO for hip containment in children with late-presenting LCPD. MATERIALS AND METHODS A quasi-prospective observational study was conducted to determine the functional outcomes of children with late-presenting unilateral LCPD who underwent VDRO between 2016 and 2021, with a minimum follow-up of two years. A retrospective chart review followed by a patient/parent-reported outcome measure using the Paediatric Outcome Data Collection Instrument (PODCI) was utilised. RESULTS Thirteen children were included in this study, with a mean age of 8.30 years (range: 7-12 years; SD: -1.493). Three children were in the early stages of the disease, modified Elizabethtown I and IIA (1 and 2, respectively). The majority of the children were in Stage IIB of the modified Elizabethtown staging (n=6), followed by Stage IIIA (n=4). The two children presenting in Stage IV of the disease were excluded from the analysis. The mean standardised and normative PODCI scores for transfer and mobility were 98.23 and 48.03, respectively. The mean standardised and normative PODCI scores for sports and physical were 93.15 and 49.76, respectively. Neither of the scores showed a statistically significant difference between the late and early stages of the disease (Transfer and Basic Mobility Scale: Standardised (p=0.273), Normative (p=0.268); Sports and Physical Functioning Scale: Standardised (p=0.618), Normative (p=0.631)). However, a higher mean PODCI score was noted for the early stages. There was no statistically significant difference between the median score and the duration since surgery. However, there was a moderate negative correlation between the time scores and the times since surgery for the late stages of the disease, viz. Stage IIB and IIIA (Transfer and Basic Mobility Scale: Standardised (-0.445), Normative (-0.450); Sports and Physical Functioning Scale: Standardised (-0.228), Normative (-0.228)). This correlation, however, did not reach a statistical significance. CONCLUSION VDRO can be regarded as a functionally rewarding option for femoral head containment in late-presenting LCPD across the evolutionary stages of the disease.

Do Weightbearing Restrictions Cause Excess Weight Gain in Children With LEGG-Calvé-Perthes Disease? J Pediatr Orthop 2023; 43:31-36. [PMID: 36084623 DOI: 10.1097/bpo.0000000000002264] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2022] [Accepted: 08/11/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND Restricted weight bearing is commonly prescribed in Legg-Calvé-Perthes Disease (LCPD), raising concerns of causing overweight or obesity. This study utilizes prospectively collected data to address the following questions: (1) does body mass index (BMI) Z-score increase over the course of LCPD follow-up; (2) is having a BMI category of normal, overweight, or obese at baseline associated with BMI Z-score changes over the course of follow-up; and (3) is the duration of weight bearing restrictions (no restrictions, <3, 3 to <6, 6 to 9, or >9 mo) associated with BMI Z-score changes. METHODS Data of 130 children aged 5 to 12 years with unilateral early-stage LCPD were extracted from an international database. Nation-specific BMI Z-scores and percentile-based weight categories were determined, and the duration of follow-up and weight bearing restrictions were calculated. Longitudinal changes in BMI Z-scores were evaluated for the 3 study questions using mixed effects linear regression models with surgery as a covariate. Sensitivity analyses were used to determine the influence of socio-cultural background (USA vs. India) for each study question. RESULTS During the 35.5±15.9 months of follow-up, no statistically significant increase in BMI Z-scores was observed across the entire cohort, or following stratification by baseline weight categories or the duration of the weight bearing restriction. Sensitivity analyses indicated that patients in the USA had no change in their BMI Z-score. When stratified by weight categories, the normal weight of US children had a small increase in their BMI Z-score (0.005 per mo, 95% confidence interval: 0.0002, 0.009), but this was not seen in other BMI categories. The cohort of Indian children had a small but significant decrease in their BMI Z-score (-0.005/mo, 95% CI: -0.009, -0.0002). After stratification by weight categories, a small decrease of the BMI Z-score was observed only in the Indian overweight children (-0.016 per mo, 95% CI: -0.027, -0.005) and no other BMI category. CONCLUSIONS Weightbearing restrictions over the course of follow-up for our cohort of children with early-stage LCPD were not associated with clinically meaningful increases of BMI Z-scores. Weight gain is multi-factorial and probably not caused by weight bearing restrictions alone. LEVEL OF EVIDENCE III Diagnostic Study.

Abstract
Background Legg–Calvé–Perthes Disease (LCPD) is a necrosis of the femoral head which affects the range of motion of the hips. Its incidence is variable, ranging from 0.4/100,000 to 29.0/ 100,000 children. Although LCPD was first described in the beginning of the past century, limited is known about its etiology. Our objective is to describe the main areas of interest in Legg–Calve–Perthes disease. Methods A review of the literature regarding LCPD etiology was performed, considering the following inclusion criteria: Studies reporting clinical or preclinical results. The research group carried out a filtered search on the PubMed and Science Direct databases. To maximize the suitability of the search results, we combined the terms ‘‘Perthes disease” OR “LCPD” OR “children avascular femoral head necrosis” with “diagnostic” OR “treatment” OR “etiology” as either key words or MeSH terms. Results In this article been described some areas of interest in LCPD, we include topics such as: history, incidence, pathogenesis, diagnosis, treatment and possible etiology, since LCPD has an unknown etiology. Conclusions This review suggests that LCPD has a multifactorial etiology where environmental, metabolic and genetic agents could be involved.

Clin Orthop Relat Res 2022; 480:587-599. [PMID: 34652293 PMCID: PMC8846348 DOI: 10.1097/corr.0000000000002010] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Accepted: 09/21/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND Perthes disease most commonly affects children 5 to 7 years old, and nonoperative management, such as weightbearing and activity restrictions, is generally recommended. In earlier research in children aged 8 to 14 years who had Perthes disease, we found that the restrictions were associated with worse mobility, but mental health or social health measures were not linked. However, Perthes disease most commonly affects children 5 to 7 years old who are more emotionally and cognitively immature. Children in this age group are beginning school and organized sports experiences while developing meaningful social relationships for the first time. Because of such different life experiences, it is important to understand the psychosocial consequences of weightbearing and activity restrictions on this specific age group, as they may help guide choices about weightbearing restrictions and mental health support. QUESTIONS/PURPOSES In patients aged 5 to 7 years with Perthes disease, we asked: (1) Are weightbearing and activity restrictions associated with worse mental health, evaluated with the Patient-reported Outcome Measurement Information System (PROMIS) depressive symptoms, anxiety, and anger questionnaires? (2) Are weightbearing and activity restrictions associated with worse social health (PROMIS peer relationships measure)? (3) Are weightbearing and activity restrictions associated with worse physical health measures (PROMIS mobility, pain interference, and fatigue measures)? (4) What other factors are associated with mental, social, and physical health measures in these patients? METHODS Data were collected from 97 patients with a diagnosis of Perthes disease. Inclusion criteria were age 5 to 7 years at the time the PROMIS was completed, English-speaking patients and parents, in the active stage of Perthes disease (Waldenstrom Stages I, II, or III) who were recommended weightbearing and activity restrictions because of worsening hip pain, poor hip ROM, femoral head deformity, as a postoperative regimen, or if there was substantial femoral head involvement on MRI [23]. Based on their weightbearing and activity restriction regimen, patients were categorized into one of four activity restriction groups (no, mild, moderate, and severe restriction). The following pediatric parent-proxy PROMIS measures were obtained: depressive symptoms, anxiety, anger, peer relationships, mobility, pain interference, and fatigue. We excluded five patients who did not meet the inclusion criteria. Of the remaining 92 patients, 21 were in the no restriction group, 21 were in the mild restriction group, 28 were in the moderate restriction group, and 22 were in the severe restriction group at the time of PROMIS administration. ANOVA was used to compare differences between the mean PROMIS T-scores of these four groups. T-scores are computed from PROMIS survey responses, and a T-score of 50 represents the age-appropriate mean of the US population with an SD of 10. A higher T-score means more of that measure is being experienced and a lower score means less of that measure is being experienced. To address the possibility of confounding variables such as Waldenstrom stage, gender, age at diagnosis, and history of major surgery, we performed a multivariable analysis to compare the association of different weightbearing regimens and the seven PROMIS measures. This allowed us to answer the question of whether weightbearing and activity restrictions are associated with worse physical, mental, and social health measures in Perthes patients aged 5 to 7 years, while minimizing the possible confounding of the variables listed above. RESULTS After controlling for confounding variables such as Waldenstrom stage, gender, age at diagnosis, and history of major surgery, we found that moderate activity restriction was associated with worse depressive symptoms (β regression coefficient = 6 [95% CI 0.3 to 12]; p = 0.04) and anxiety (β = 8 [95% CI 1 to 15]; p = 0.02) T-scores than no restrictions. The mild (β = -7 [95% CI -12 to -1]; p = 0.02), moderate (β = -15 [95% CI -20 to -10]; p < 0.001), and severe (β = -23 [95% CI -28 to -18]; p < 0.001), restriction groups had worse mobility T-scores than the no restriction group. Weightbearing and activity restrictions were not associated with anger, peer relationships, pain interference, and fatigue measures. Waldenstrom Stage II disease was associated with worse pain interference than Waldenstrom Stage III (β = 7 [95% CI 0.4 to 13]; p = 0.04). A history of major surgery was associated with worse anger scores (β = 18 [95% CI 3 to 33]; p = 0.02). The child's gender and age at diagnosis had no association with any of the seven PROMIS measures. CONCLUSION Moderate weightbearing and activity restrictions are associated with worse depressive symptoms and anxiety in patients with Perthes disease aged 5 to 7 years, after controlling for Waldenstrom stage, gender, age at the time of diagnosis, and history of surgery. Considering the discoveries in this study and in our previous study, for patients 5 to 7 years old, we recommend that providers discuss the potential for mental health changes with moderate weightbearing restrictions with patients and their families. Furthermore, providers should monitor for worsening mental health symptoms at each follow-up visit and refer patients to a clinical child psychologist for support when appropriate. Future studies are needed to assess the effects of these restrictions on mental health over time and after patients are allowed to return to normal activities.

Abstract
BACKGROUND Assessing the severity of Legg-Calve-Perthes disease is important for treatment decision-making and determining prognosis. Perfusion magnetic resonance imaging (MRI) scans have improved our ability to assess femoral head hypoperfusion, and the use of an image analysis software called HipVasc (Scottish Rite for Children, Dallas TX) has allowed precise quantification for research purposes. In the clinical setting, using HipVasc software is not practical, and visual estimation is used to assess hypoperfusion. Currently, the reliability of visual estimation is unknown. The purpose of this study was to determine the reliability and validity of visual estimation of hypoperfusion on perfusion MRI and compare the results to measurements obtained with the HipVasc software. METHODS Fourteen pediatric orthopaedic surgeons, divided into 4 groups, participated in this study. Each surgeon completed a 30-minute in-person training on HipVasc before proceeding. Stratified by category of severity, 122 MRIs were randomly assigned to 1 of the 4 groups so that each group member measured the same set of ∼30 MRIs. Each surgeon documented their visual estimation of hypoperfusion first, then used HipVasc to measure the hypoperfusion and recorded their results. Interobserver reliability was assessed at the group level by calculating the intraclass correlation coefficient. RESULTS Good correlation and reliability was found between the visual estimate and HipVasc measurements with an overall mean intraclass correlation coefficient of 0.87 and mean Pearson coefficient of 0.90. The mean interobserver reliability of visual estimation was 0.84. Observers had a tendency to overestimate hypoperfusion with visual estimation. CONCLUSIONS This study demonstrates the reliability and validity of visual estimation as a clinically applicable method for determining femoral head hypoperfusion. Our study is the first to measure the reliability of visual estimation and HipVasc with a large cohort of clinicians, specifically pediatric orthopaedic surgeons with varied experience in graphical software analysis. We recommend using visual estimation as a clinically applicable method to make treatment decisions, and its accuracy is comparable to HipVasc software analysis.

[PMID: 33394755 PMCID: PMC8133300 DOI: 10.1097/corr.0000000000001608] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2020] [Accepted: 11/23/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND Weightbearing and activity restrictions are commonly prescribed during the active stages of Perthes disease. These restrictions, ranging from cast or brace treatment with nonweightbearing to full weightbearing with activity restrictions, may have a substantial influence on the physical, mental, and social health of a child. However, their impact on the patient's quality of life is not well-described. QUESTIONS/PURPOSES After controlling for confounding variables, we asked (1) are restrictions on weightbearing and activity associated with physical health measures (as expressed by the Patient-Reported Outcome Measurement Information System [PROMIS] mobility, PROMIS pain interference, and PROMIS fatigue) of children in the active stages of Perthes disease? (2) Are these restrictions associated with poorer scores for mental health measures (PROMIS depressive symptoms and PROMIS anxiety)? (3) Are these restrictions associated with poorer scores for social health measures (PROMIS peer relationships)? METHODS Between 2013 and 2020, 211 patients with Perthes disease at a single institution were assigned six PROMIS measures to assess physical, mental, and social health. Patients who met the following eligibility criteria were analyzed: age 8 to 14 years old, completion of six PROMIS measures, English-speaking, and active stage of Perthes disease (Waldenstrom Stage I, II, or III). Weightbearing and activity restrictions were clinically recommended to patients in the initial through early reossification stages of Perthes disease when patients had increasing pain, loss of hip motion, loss of hip containment, progression of femoral head deformity, increased hip synovitis, and femoral head involvement on MRI or as a postoperative regimen. Patients were categorized into four intervention groups based on weightbearing and activity regimen. We excluded 111 patients who did not meet the inclusion criteria. The following six pediatric self-report PROMIS measures were assessed: mobility, pain interference, fatigue, depressive symptoms, anxiety, and peer relationships. Of the 100 patients, 36 were categorized into the no-restriction regimen, 27 into the mild-restriction regimen, 25 into the moderate-restriction regimen, and 12 into the severe-restriction regimen at the time of PROMIS administration. The median (range) age at diagnosis was 8 years old (range 2 to 13 years). There were 85 boys and 15 girls. Eleven patients had hips in Waldenstrom Stage I, 10 were in Stage II, and 79 were in Stage III. Forty-four patients had hips classified as lateral pillar B and 47 patients as lateral pillar C. Nine patients had not reached the mid-fragmentation stage for appropriate lateral pillar classification by the time they took the PROMIS survey. ANOVA was used to compare differences between the mean PROMIS T-scores of these weightbearing/activity regimens. Results were assessed with a significance of p < 0.05 and adjusted for Waldenstrom stage, gender, age at diagnosis, and history of major surgery using multivariate regression analysis. RESULTS After controlling for confounding variables, the mild- (β regression coefficient -15 [95% CI -19 to -10]; p < 0.001), moderate- (β -19 [95% CI -24 to -14]; p < 0.001), and severe- (β -25 [95% CI -30 to -19]; p < 0.001) restriction groups were associated with worse mobility T-scores compared with the no-restriction group, but no association was detected for the pain interference or fatigue measures. Weightbearing and activity restrictions were not associated with mental health measures (depressive symptoms and anxiety). Weightbearing and activity restrictions were not associated with social health measures (peer relationships). Earlier Waldenstrom stage was associated with worse pain interference (β 10 [95% CI 2 to 17]; p = 0.01) and peer relationships scores (β -8 [95% CI -15 to -1]; p = 0.03); female gender was linked with worse depressive symptoms (β 7 [95% CI 2 to 12]; p = 0.005) and peer relationships scores (β -6 [95% CI -12 to 0]; p = 0.04); and earlier age at diagnosis was associated with worse peer relationships scores (β 1 [95% CI 0 to 2]; p = 0.03). History of major surgery had no connection to any of the six PROMIS measures. CONCLUSION We found that weightbearing and activity restriction treatments are associated with poorer patient-reported mobility in the active stages of Perthes disease after controlling for Waldenstrom stage, gender, age at diagnosis, and history of surgery. Weightbearing/activity restrictions, however, are not associated with pain interference, fatigue, depressive symptoms, anxiety, and peer relationships. Understanding how these treatments are associated with quality of life in patients with Perthes disease can aid in decision-making for providers, help set expectations for patients and their parents, and provide opportunities for better education and preparation. Because of the chronic nature of Perthes disease, future studies may focus on longitudinal trends in patient-reported outcomes to better understand the overall impact of this disease and its treatment.

Abstract
Aims Perthes’ disease is a condition leading to necrosis of the femoral head. It is most common in children aged four to nine years, affecting around one per 1,200 children in the UK. Management typically includes non-surgical treatment options, such as physiotherapy with/without surgical intervention. However, there is significant variation in care with no consensus on the most effective treatment option. Methods This systematic review aims to evaluate the effectiveness of non-surgical interventions for the treatment of Perthes’ disease. Comparative studies (experimental or observational) of any non-surgical intervention compared directly with any alternative intervention (surgical, non-surgical or no intervention) were identified from: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMcare, Allied and Complementary Medicine Database (AMED), and the Physiotherapy Evidence Database (PEDro). Data were extracted on interventions compared and methodological quality. For post-intervention primary outcome of radiological scores (Stulberg and/or Mose), event rates for poor scores were calculated with significance values. Secondary outcomes included functional measures, such as range of movement, and patient-reported outcomes such as health-related quality of life. Results In all, 15 studies (1,745 participants) were eligible for inclusion: eight prospective cohort studies, seven retrospective cohort studies, and no randomized controlled trials were identified. Non-surgical interventions largely focused on orthotic management (14/15 studies) and physical interventions such as muscle strengthening or stretching (5/15 studies). Most studies were of high/unknown risk of bias, and the range of patient outcomes was very limited, as was reporting of treatment protocols. Similar proportions of children achieving poor radiological outcomes were found for orthotic management and physical interventions, such as physiotherapy or weightbearing alteration, compared with surgical interventions or no intervention. Conclusion Evidence from non-randomized studies found no robust evidence regarding the most effective non-surgical interventions for the treatment of children with Perthes’ disease. Future research, employing randomized trial designs, and reporting a wider range of patient outcomes is urgently needed to inform clinical practice. Cite this article: Bone Jt Open 2020;1-12:720–730.

Abstract
This systematic review explores the relevant literature to assess the efficacy of the use of arthrodiastasis in the management of Perthes disease. Until this moment, arthrodiastasis is not well established for its use in Perthes disease as opposed to other containment procedures. Furthermore, there are no clear indications for its use in this disease. Twelve articles were matched to the inclusion criteria and all articles were reviewed and radiological and clinical data were collected and compiled. As regards the hip flexion range of motion, the average preoperative flexion range of motion was 55.32°, while the postoperative was 90°. The average preoperative hip abduction range of motion was 12.28° and postoperative was 35.28°. Mean preoperative hip internal rotation range of motion was 8.69° and postoperatively was 24.93°. Mean preoperative external rotation range of motion was 21.73°, while the postoperative range was 33.71°. Final Stulberg classification was ascertained showing most patients ending with stages two and three. Complications were also assessed with most of which being superficial pin tract infections. The use of arthrodiastasis is a valid treatment option for Perthes disease; however, more articles need to be produced showing comparative data of arthrodiastasis versus other containment procedures. Level of evidence - level 1: systematic review.

Abstract
The limping child is a common presentation to paediatric services. In most instances the cause is benign with few, if any, investigations required. There is, however, always that concern that the limping child may have an underlying limb-threatening or life-threatening disease. This poses a challenge to clinicians, who must find that balance between correctly identifying disease early and avoiding the risks and harms of overinvestigation. In this article we discuss the diagnostic approach to the limping child and present a structure for assessment, investigation and risk management.

Abstract
BACKGROUND Untreated Perthes disease can lead to osteoarthritis by the fourth decade. The treatment is conservative for children <6 years, operative within the age group of 6-9 years. Late onset Perthes, older than 9 years or more, are notorious with the aggressive course with poor outcome. However, literature do not come to a consensus between conservative and operative management. This study evaluates the clinical and radiological outcome of varus derotation osteotomy (VDRO) in Perthes disease presenting late with age 8 years or more. MATERIALS AND METHODS 15 children (13 males and 2 females) with the mean age of 9.4 years belonging to modified Elizabethtown classification Stage IB, IIA, IIB treated with open wedge VDRO between 2008 and 2014 were included in this study. Seven patients (46.67%) were of >10 years of age at presentation. All patients had limitation of abduction and internal rotation. Eight patients (53.33%) had pain at the hip and 12 patients (80%) had limp. Mean time between diagnosis and corrective surgery was 3 weeks. RESULTS The evaluation was done using caput index (CI) and epiphyseal quotient (EQ) and articulotrochanteric distance radiologically, range of motion and Harris Hip Score for clinical outcome. All the measurements were carried out on pre- and postoperative X-rays after 3 years followup and compared with the contralateral normal hip. After a mean followup period of 3.4 years, we noted the statistically significant difference between pre- and postoperative values. We noted that all (100%) children in Stage IB, IIA and 50% children in Stage IIB achieved satisfactory results. There was a significant change (P = 0.000) in CI among all the patients after surgery. The final EQ after 3 years of VDRO was 0.606 and was significant (P = 0.0000). CONCLUSION In our opinion, based on the encouraging short term radiological and clinical outcomes, VDRO may be regarded as a treatment procedure for late presenting Perthes disease in stage IB, IIA, IIB.

Abstract
Legg-Calve-Perthes disease (LCPD) is the insidious onset of idiopathic avascular necrosis of the hip in the pediatric population. The disease encompasses a wide spectrum of pathology, from mild with no long-term sequelae to severe with permanent degenerative change of the hip joint. A pediatric patient with hip pathology may initially only present with knee or thigh pain, thus obligating the clinician to maintain awareness about the hip during examination. Common physical examination findings include deficits in hip abduction and internal rotation, along with Trendelenburg gait in late stages. Plain radiographs demonstrate changes in the anterolateral aspect of the femoral head, sometimes only seen on the frog lateral X-ray in early stages. Treatment options aim to restore range of motion and maintain adequate coverage of the femoral head. When appropriate, surgery is used to reorient the femoral head or pelvis to maintain coverage.

Abstract
BACKGROUND Legg-Calve´-Perthes disease (LCPD) is an idiopathic avascular necrosis of the femoral head. There are multiple approaches to the treatment of LCPD ranging from conservative management to a wide variety of surgical methods. Conservative management necessitates extreme degrees of abduction in an orthosis for a longer period of time which further jeopardize capital femoral head vascularity. Surgical containment methods are used in cases where it is desirable. Initial surgical containment methods are varus or varus-derotational osteotomy of the proximal femur or an innominate osteotomy as described by Salter and other pelvic osteotomies. The purpose of this study was to describe the early results of containment methods by one-stage combined osteotomy (femoral varus osteotomy and Salter innominate osteotomy) in patients with severe LCPD. MATERIALS AND METHODS 23 children were operated in the age group of 4-9 years for LCPD by one-stage combined osteotomy procedure between January 2005 and June 2012. There were 19 boys and 4 girls, left hip involved in 10 cases and right in 13 cases. Preoperatively, they were classified according to Catterall, Joseph's stage and lateral pillar (LP) classification. Postoperatively, clinical results were evaluated in accordance with Ratliff classification and radiological assessment was made by Mose's index, modified Stulberg classification and Epiphyseal extrusion index. RESULTS Seventeen hips were Catterall group III, 6 in group IV and all had two or more "head-at-risk" signs. There were 2 patients with stage IIA, 15 were in stage IIB and 6 were in stage IIIA as classified by Joseph's stage of disease. According to LP classification, 11 patients were group B, 3 were group B/C and 9 were in group C. At an average followup of 5.4 years (range 2-9.5 years), the clinical results were good in 12, fair in 9 and poor in 2. According to Mose scale, 8 patients had good results, 13 fair results and 2 had poor results. Based on modified Stulberg classification, there were 10 patients in group A, 11 in group B and 2 in group C. The average preoperative extrusion index was 23.6% which improved postoperatively to 9.5% at latest followup. CONCLUSIONS The surgical treatment of LCPD with the best expected outcome is still a challenge. Advanced containment methods by one-stage combined osteotomy can be considered as an alternative treatment where femoral head subluxation or deformity which makes containment difficult or impossible by more conventional methods.

Abstract
BACKGROUND Legg-Calvé-Perthes Disease (Perthes' disease) is a childhood hip disorder initiated by ischemic necrosis of the growing femoral head. So far, the etiology and pathogenesis of Perthes' disease is poorly understood. MATERIALS AND METHODS Avascular osteonecrosis rat model was established to mimic the pathophysiological changes of femoral head necrosis. The chondrocytes of newborn Sprague-Dawley rats were isolated and cultured in hypoxic and normoxic condition. The expression characteristic of the hypoxia-inducible factor-1 alpha (HIF-1α) was evaluated both in vivo and in vitro models. Vascular endothelial growth factor (VEGF) and apoptotic genes in chondrocytes treated with normoxia and hypoxia were also studied. RESULTS HIF-1α expression increased greatly after ischemic operation and kept at relative high level in the arthromeningitis stage and declined in the stages of osteonecrosis and reconstruction. The HIF-1α mRNA levels of chondrocytes incubated at hypoxia were significantly higher than the cells treated with normoxia at 24 and 72 hours. Hypoxia inhibited VEGF expression; chondrocytes could oppose this inhibition manifested by the increasing of VEGF mRNA level after 72 hours hypoxia. The expression of apoptotic genes, Casp3, Casp8 and Casp9, elevated in chondrocytes after hypoxia with time differences. CONCLUSION Hypoxia might be an etiological factor for femoral head necrosis, HIF-1α, VEGF as well as apoptotic genes participated the pathophysiological process of ischemic osteonecrosis.
