Abstract
BACKGROUND The etiology and pathogenesis of slipped capital femoral epiphysis (SCFE) are attributable to abnormalities of the proximal femoral epiphysis. This study aimed to examine if there is a difference in the bone age of patients diagnosed with SCFE compared with patients without hip pathology. METHODS We identified a consecutive series of patients treated for SCFE between December 2012 and December 2019 from a departmental database. Retrospective chart review was performed to collect demographic information and patient medical history. We then obtained a control group of statistically similar patients based on age and sex. These patients did not have hip pathology or medical comorbidities that could alter their bone age. The modified Oxford bone score (mOBS) was calculated for both groups by 3 blinded reviewers. We excluded patients with unstable slips, endocrine disorders, and inadequate imaging. RESULTS We identified 60 patients with stable idiopathic SCFE during the study period; 45 met inclusion criteria and were included in the final analysis. There were 27 males and 18 females. The average age of patients with SCFE was higher in males than females (12.6 vs. 11.1, P<0.01). Patients in the comparison cohort did not differ significantly from the SCFE cohort in terms of age (11.6 vs. 12.0, P=0.06) or sex (P=0.52). The comparison group's median mOBS was significantly higher than the SCFE group (22.5 vs. 20.5, P<0.01). The difference in the mOBS between male and female patients in the SCFE group approached significance (20.0 vs. 21.0, P=0.05). The weighted κ coefficient was 0.93. CONCLUSIONS Patients with SCFE have a decreased bone age compared with patients without hip pathology. Male patients with SCFE were more likely to be older compared with female patients. LEVEL OF EVIDENCE Level IV-retrospective study.

Abstract
Globally, obesity is on the rise with ~ 30% of the world’s population now obese, and childhood obesity is following similar trends. Childhood obesity has been associated with numerous chronic conditions, including musculoskeletal disorders. This review highlights the effects of childhood adiposity on bone density by way of analyzing clinical studies and further describing two severe skeletal conditions, slipped capital femoral epiphysis and Blount’s disease. The latter half of this review discusses bone remodeling and cell types that mediate bone growth and strength, including key growth factors and transcription factors that help orchestrate this complex pathology. In particular, the transcriptional factor peroxisome proliferator-activated receptor gamma (PPARγ) is examined as it is a master regulator of adipocyte differentiation in mesenchymal stem cells (MSCs) that can also influence osteoblast populations. Obese individuals are known to have higher levels of PPARγ expression which contributes to their increased adipocyte numbers and decreased bone density. Modulating PPAR*gamma* signaling can have significant effects on adipogenesis, thereby directing MSCs down the osteoblastogenesis pathway and in turn increasing bone mineral density. Lastly, we explore the potential of PPARγ as a druggable target to decrease adiposity, increase bone density, and be a treatment for children with obesity-induced bone fractures.

Abstract
PURPOSE Early diagnosis and treatment of slipped capital femoral epiphysis (SCFE) is important to prevent slip progression and avoid complications. We sought to determine if MRI findings in patients with unilateral SCFE could indicate 'pre-slip' or predict future SCFE in the contralateral hip. METHODS A prospective study evaluated patients with unilateral SCFE over a two-year period. MRI of the asymptomatic hip was performed within the perioperative period. Patients were followed with radiographs until a contralateral slip occurred or until physeal closure. Demographics, clinical stability, severity, posterior slope angle (PSA), modified Oxford Bone Score (mOBS) and patency of the triradiate cartilage were recorded and statistical analysis performed. RESULTS In all, 33 of 54 patients with unilateral SCFE were enrolled into the study. In all, 29 (87.8%) had complete follow-up. Five of the enrolled patients (15.2%) developed a sequential slip requiring in situ pinning. Six of 33 (18.2%) patients had positive MRI findings: four of which proceeded to sequential SCFE and two which did not. One sequential slip had a negative MRI. PSA predicted 1/11 sequential slips (sensitivity 9.09%, specificity 81.4%, positive predictive value (PPV) 11.1%, negative predictive value (NPV) 77.8%) and mOBS predicted 5/11 sequential slips (sensitivity 45.5%, specificity 93%, PPV 62.5%, NPV 87%). An open triradiate cartilage was present in 8/11 patients with sequential slips (sensitivity 72.7%, specificity 81.4%, PPV 50%, NPV 92.1%). CONCLUSION MRI findings consistent with 'pre-slip' were present in 66.7% of patients who developed a sequential SCFE. Further study on the utility/sensitivity of MRI in predicting sequential SCFE is warranted. LEVEL OF EVIDENCE II, diagnostic.

Abstract
We performed a meta-analysis of studies evaluating the seasonality of slipped upper femoral epiphysis (SUFE). In addition we compared the monthly incidences of SUFE at latitudes greater than 40° with the established serum 25-hydroxyvitamin levels for children resident at a comparative latitude. In total 11 relevant studies were identified, involving 7451 cases of SUFE. There was significant variation in the month of onset of SUFE. The degree of variability increased with increasing latitude. The modal month of symptomatic onset was dependent upon latitude. At latitudes greater than 40°, the most common month of onset was August. At latitudes between 20° and 40°, this was earlier in the calendar year, around April. The seasonal variability was statistically significant (p<0.0001 and p<0.005 for latitudes >40° and 20°-40° respectively). The pattern of monthly fluctuation in onset of SUFE very closely mirrored the monthly pattern of variation for serum 25-hydroxyvitamin D3. There was a very strong positive correlation (Spearman rank rho = + 0.8, p = 0.001). There is a monthly variation in incidence of SUFE. The degree of variability increases with increasing latitude. There may be an association with vitamin D. We hypothesise that elevated serum 25-hydroxyvitamin D3 accelerates growth thus rendering the growth plate vulnerable to slippage in analogous manner to the pubertal growth spurt.

Abstract
OBJECTIVE To determine whether curve magnitude of scoliosis at presentation correlates with BMI. METHODS Retrospective chart review of 180 patients presenting with scoliosis was performed. Curve pattern and magnitude, Risser status, occurrence of surgery, zip code, height and weight, race, and insurance status were recorded. Relationships were examined by Spearman rank and Pearson correlations, and logistic regression analysis was used to determine odds ratios. RESULTS For both thoracic and lumbar curve patterns, there was a correlation between BMI and curve magnitude. Spearman rank correlation was 0.19 for thoracic (P = .03) and 0.24 for lumbar curves (P = .02). Overweight or obese patients were not more likely, however, to present with curves at higher risk of progression or more likely to have surgical intervention. With respect to potential confounding socioeconomic variables, thoracic curve magnitude was negatively correlated with median family income (Spearman rank correlation -0.17, P = .04). Curve magnitude was not correlated with race, distance, or insurance payer. CONCLUSIONS Patients with high BMI and scoliosis are more likely to present with larger curves, but not more likely to require surgery. This is concerning because of the national trend of increasing childhood obesity and because scoliosis treatment may be more complicated in larger curves. Socioeconomic factors may also be barriers to access.

Abstract
Objective To identify anatomical changes and skeletal maturity through radiographic analysis,
allowing more accuracy for indication of surgical management of non-slipped hips in
patients with epiphysiolisys. Method A retrospective study of the radiographs of 61 patients followed until the end of
skeletal growth, assigned to two groups: 37 patients with unilateral epiphysiolysis, and
24 patients with contralateral epiphysiolysis diagnosed during follow-up. The skeletal
maturity was evaluated using pelvis radiographs (Oxford method) and compared between the
groups for patients of the same gender. In addition, the Southwick angle (in
anteroposterior and in Lauenstein view), physeal sloping angle and physeal posterior
sloping angle were compared as well. Results Skeletal maturity showed a statistically significant difference between the two groups
for both genders. It was observed that the lateral view of the Southwick angle is
mathematically equal to the physeal posterior sloping angle, and were the only ones to
show relevant differences between the groups. Conclusion The Oxford method and the Southwick angle in Lauenstein view can be utilized as
parameters to help the physician to better indicate the prophylactic surgical treatment
of the contralateral hip, in patients with slipped capital femoral epiphysis (SCFE).

Abstract
The etiology of slipped capital femoral epiphysis (SCFE) is unknown with many insights coming from epidemiologic/demographic information. A systematic medical literature review regarding SCFE was performed. The incidence is 0.33/100,000 to 24.58/100,000 children 8 to 15 years of age. The relative racial frequency, relative to Caucasians at 1.0, is 5.6 for Polynesians, 3.9 for Blacks, and 2.5 for Hispanics. The average age is 12.0 years for boys and 11.2 years for girls. The physiologic age when SCFE occurs is less variable than the chronologic age. The average symptom duration is 4 to 5 months. Most children are obese: >50% are >95th percentile weight for age with average BMI is 25-30 kg/m(2). The onset of SCFE is in the summer when north of 40°N. Bilaterality ranges from 18 to 50%. In children with bilateral involvement, 50-60% present with simultaneous SCFEs and those who present with a unilateral SCFE and subsequently develop a contralateral SCFE do so within 18 months. The age at presentation is younger for those who present with a unilateral SCFE and later develop a contralateral SCFE. The age-weight, age-height, and height test are useful to differentiate between an idiopathic and atypical SCFE.

Abstract
Chondrocytes and adipocytes are two differentiated cell types which are both derived from mesenchymal cells. The purpose of this study was to investigate whether peroxisome proliferator-activated receptor-γ (PPARγ), a transcription factor involved in lineage determination during adipogenesis, is able to induce adipogenic differentiation in growth plate chondrocytes. Isolated epiphyseal chondrocytes were infected with a PPARγ adenovirus or treated with the PPARγ agonist ciglitazone. Both of these treatments resulted in lipid droplet accumulation and expression of the adipogenic markers aP2, lipoprotein lipase, and adipsin in chondrocytes. Proteoglycan matrix synthesis was decreased in the PPARγ-infected cells, as was the expression of the chondrogenic genes Col2a1 and aggrecan. Growth plate cells transfected with a PPARγ expression plasmid under the control of the collagen α1(II) promoter also demonstrated a similar adipogenic changes. Terminal differentiation of growth plate chondrocytes induced by thyroid hormone was also inhibited by overexpression of PPARγ and ciglitazone treatment, with decreased expression of alkaline phosphatase and Runx2/Cbfa1 genes. These in vitro data suggest that PPARγ is able to promote adipogenic differentiation in growth plate chondrocytes, while negatively regulating chondrogenic differentiation and terminal differentiation.

Abstract
OBJECTIVE To examine associations of major complications after surgical treatment of slipped upper femoral epiphysis (SUFE) with condition- and treatment-related risk factors. STUDY DESIGN This systematic review and meta-analysis of observational studies used an electronic literature search of Embase and Medline supplemented by a manual search of bibliographies. The studies enrolled children and adolescents with SUFE, defined stable and unstable disease, and reported at least 3 primary endpoints: avascular necrosis (AVN), chondrolysis, and reoperation. Random-effects meta-regression analysis was performed when possible. RESULTS The weighted risk for AVN, derived from intercept-only meta-regression, was estimated as 5.3% (95% confidence interval [CI], 3.4%-7.2%). Patients with unstable slips had a 9.4-fold greater risk of developing AVN. Instability proved to be an independent predictor for AVN. The weighted risk of chondrolysis was 0.8% (95% CI, 0.2%-1.4%), associated with unstable slips and osteotomies. The risk of reoperation was estimated at 5.5% (95% CI, 1.7%-9.3%). Loss of fixation was the primary reason for reoperation. CONCLUSIONS Current evidence indicates that unstable slips are at a significantly higher risk for AVN than stable slips, regardless of the attempted surgical approach. Little clinical information is available regarding chondrolysis and reoperation in relation to the stability of the physis.

Abstract
Although rare, injury to the triradiate cartilage is both a diagnostic and therapeutic challenge. Trauma to the triradiate cartilage or its blood supply can adversely affect acetabular development due to premature physeal closure. A shallow acetabulum with a lateralized hip joint that is prone to subluxation, premature degenerative changes, chronic pain, and functional limitations can result. We present a case of an acetabular fracture with injury to the triradiate cartilage after low-energy trauma in an adolescent male treated nonoperatively and healed without complications.

Abstract
As the increasing prevalence of overweight and obese children is approaching epidemic proportions in North America, this study was designed to investigate whether Body Mass Index (BMI) and age- and gender-specific percentile Body Mass Index (BMI %) are associated with the likelihood of being listed for surgery for Blount disease after initial presentation to a tertiary referral centre. In a restrospective consecutive sample of 102 children with an average age of 5.9 +/- 4.3 years, it was determined that there was a significant association between BMI and BMI% and being listed for surgery, after adjusting for the effects of the child's age and gender, with mean odds ratios of 1.30 (95% confidence interval 1.02-1.60) and 1.05 (95% confidence interval 1.01-1.09) respectively. When the sample was subgrouped into infantile (less than 3 years of age) and late-onset (greater than 3 years of age), BMI and BMI% were still significantly associated with the children being listed for surgery in the late-onset group with mean odds ratios 2.75 (95% confidence interval 1.03-7.33) and 1.09 (95% confidence interval 1.01-1.18) respectively. However, of the two measures only the BMI was significant in the infantile group with an odds ratio of 1.27 (95% confidence interval 1.01-1.60). Should these associations be real then measures aimed at decreasing weight in children may have some effect on the number of children undergoing surgery for the treatment of Blount disease.

Abstract
A narrow window of bone age (BA) in slipped capital femoral epiphysis (SCFE) was described a decade ago. Children now mature younger. Does the BA narrow window still exist? It is the purpose of this study to investigate this question. A retrospective review of children with idiopathic SCFE (1998-2003) was performed. The initial study data ("past") were used as a comparison. Anteroposterior pelvis radiographs were scored for BA (Oxford method) in 108 children. Only the first radiograph was used for children with sequential bilateral SCFEs. There were 67 boys and 41 girls. There were 73 children with unilateral and 35 with bilateral SCFEs. Chronological age (CA) was 12.4+/-1.8 years; Oxford score, 39+/-3 years; and Oxford BA (OXBA), 13.2+/-1.3 years. The recent children were younger (12.1 and 13.2 years; P=0.001), with lower OXBA (29.0 and 31.4; P=0.000003). When converted into years, there was no significant difference between the recent and past children (recent data, 13.1 years; past data, 13.5 years; P=0.18). Chronological age was higher in boys than in girls (12.7 and 11.6 years, respectively; P=0.0008), and so was BA (13.9+/-1.0 and 12.0 years, respectively; P<10). There were no differences in BA score between boys and girls (boys, 29.5; girls, 29.9; P=0.49). The recent data demonstrated the same narrow window of BA. The CA range for the boys' SCFE was 8.4 years, whereas the OXBA was 4.0 years. The CA range for girls was 5.3 years, whereas the OXBA was 2.3 years. Those with unilateral SCFEs were older than those with bilateral SCFEs in CA (12.7 and 11.7 years, respectively; P=0.013), but not in BA (29.8 and 29.4; P=0.51). All SCFEs are present, on average, at an OXBA of 29, regardless of sex, symptom duration, or unilateral/bilateral nature. This study has reaffirmed the narrow window of BA in SCFE, with a BA range approximating 50% of CA range.

Abstract
Approximately 20% of children with idiopathic slipped capital femoral epiphysis (SCFE) have bilateral disease. Predicting which patients will develop problems with both hips remains difficult. This is the first study to evaluate the relationship between body mass index (BMI) and unilateral and bilateral SCFEs. Height and weight measurements of patients presenting with SCFE to our institution were obtained and used to calculate the BMI. Of the 54 patients enrolled in the study, 16 ultimately had bilateral disease. The mean BMI of patients with bilateral disease was significantly greater than that of patients with unilateral disease. In addition, patients presenting with unilateral involvement who progressed to bilateral disease had a significantly greater average BMI than patients who did not progress. Elevated BMI is associated with SCFE, especially bilateral SCFE.

Abstract
Different anatomic parameters were measured on radiographs of the healthy hip of 47 patients with unilateral slipped capital femoral epiphysis (SCFE). Data were compared with those from 36 hips of 23 healthy adolescents matched in age, weight, and stature. During 5 years of follow-up, eight patients with unilateral SCFE developed slippage of the contralateral side. Patients with unilateral SCFE had a lower physis-diaphysis angle and a larger angle of physeal sloping in the AP view than controls, reflecting a more vertical orientation of the capital femoral physis. In the axial view, control patients had a mean value of the posterior sloping angle of the capital femoral physis of 5 degrees, compared with 12 degrees in unilateral SCFE cases and 18 degrees in patients developing bilateral SCFE. The risk of developing bilateral disease can be predicted by measuring hip morphometric parameters, the most important factor being the posterior sloping of capital femoral physis in the axial view. Prophylactic pinning of the healthy contralateral side should be strongly recommend only in patients with unilateral SCFE showing an axial posterior sloping angle of the physis of over 12 degrees.

Abstract
Slipped capital femoral epiphysis (SCFE) and Down syndrome are both uncommon in the population at large, and rarely are both conditions present in a single individual. Institutional records were searched for both Down syndrome and SCFE. At least 2 years of follow-up was required. Eight patients were identified. At presentation four patients could not walk due to pain and four could walk. Six of eight hips presented with grade III SCFE. Four hips were treated with internal fixation in situ and four were manipulatively reduced in the operating room at the time of fixation with percutaneous screws or pins. Three hips healed uneventfully. Five hips developed aseptic necrosis (three partial, two whole head). This small retrospective study suggests an extremely high rate of complications in adolescents with Down syndrome and SCFE.

Abstract
OBJECTIVE To determine clinical, radiographic, and histologic abnormalities in adult cats > 1 year old with spontaneous (ie, nontraumatic) femoral capital physeal fractures. DESIGN Retrospective study. ANIMALS 26 cats. PROCEDURE Medical records of cats > 1 year old with femoral capital physeal fractures and no history of trauma were examined. RESULTS Mean +/- SD age of the cats was 22.5 +/- 6.5 months. Twenty-five cats were neutered males. Mean weight of the cats was significantly greater than mean weight of a group of age- and sex-matched control cats. Of 16 cats for which age at the time of neutering was known, 14 had been neutered before 6 months of age. Nine cats had bilateral fractures. Severity of femoral neck osteolysis and sclerosis increased with increased duration of clinical signs. The contralateral femoral capital physis, distal femoral physes, and proximal tibial physes were radiographically open in 13 of 18,19 of 24, and 24 of 24 cats, respectively. Histologically, the epiphysis contained normal articular cartilage and bone, but attached growth plate cartilage lacked the normal columnar arrangement of chondrocytes. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that adult cats with spontaneous femoral capital physeal fractures were most likely to be heavier, neutered males with delayed physeal closure.

Abstract
Slipped capital femoral epiphysis (SCFE), though a relatively common disorder, is frequently missed on initial presentation. Symptoms can be vague, the physical examination unrevealing, and radiographic abnormalities subtle. Prompt diagnosis of SCFE is important, however, to improve clinical outcome. The emergency physician needs to remain vigilant for this diagnosis to avoid this orthopedic pitfall. This article examines the clinical presentation, diagnostic techniques, and management options applicable to the emergency physician in the treatment of SCFE.

Abstract
BACKGROUND The risk of a contralateral slip in patients who are first seen with a unilateral slipped capital femoral epiphysis has been reported to be 2335 times higher than the risk of an initial slip. The overall prevalence of bilaterality varies widely throughout the literature, with some reports indicating rates as high as 80%. This finding has led many authors to recommend prophylactic pinning of the contralateral asymptomatic hip in patients presenting with a unilateral slipped capital femoral epiphysis. METHODS A decision analysis model with probabilities for the occurrence of contralateral slip and for the severity of slip at different intervals of follow-up was used in the present study. These probabilities were compared with those for various outcomes when the contralateral hip is prophylactically pinned. Scores representing long-term outcome, according to the Iowa hip-rating system, were used in the model as a measure of utility. The probabilities of contralateral slip and the rates of slip severity were taken from large retrospective series. All meaningful clinical scenarios with regard to long-term outcome for the hip were considered in the model. Variables of uncertainty were subjected to sensitivity analyses in order to explore the effect on outcome over the range of plausible values for variables of interest. RESULTS The results showed a benefit in the long-term outcome for patients who had prophylactic pinning of the contralateral hip. The threshold level at which a benefit is obtained with prophylactic pinning is expressed according to the rates of sequential slip, rates of slips overlooked at follow-up, and complications associated with prophylactic pinning of the contralateral hip. CONCLUSIONS The decision model shows that, when pooled data are used to predict probabilities of sequential slip, treatment of the contralateral hip with prophylactic pinning is beneficial to the long-term outcome for that hip. When considering prophylactic pinning of the contralateral hip, the clinician should use sound clinical judgment with respect to the age, sex, and endocrine status of the patient. Long-term follow-up studies are needed to establish the efficacy of prophylactic pinning, but the predictions in the present study, which are based on findings in the literature, support the safety of this procedure.

Abstract
Slipped capital femoral epiphysis (SCFE) mainly occurs in pubertal children and is associated with delayed skeletal maturation, obesity, high growth velocity and tall stature. Furthermore, SCFE often coincides with endocrine disorders. This is the first report of a possible relationship between SCFE and GnRH agonist treatment: four patients developed SCFE during or shortly after treatment with GnRH agonists was stopped. We compared the clinical aspects of these patients with patients described in the literature who developed SCFE. Puberty started at the age of 3.3, 9.6, 0.0 and 5.6 years respectively. One patient developed sequential SCFE of both hips. SCFE occurred at the age of 11.9 (patient 1), 12.7 (patient 2), 14.3 (patient 2), 11.3 (patient 3) and 11.3 (patient 4) years. Of the five incidences of SCFE, one occurred during GnRH agonist treatment and four shortly after treatment was stopped. None of our patients met the typical criteria seen in SCFE and no 'regular' characteristics of patients with SCFE could be designated. Probably the hormonal changes during and shortly after treatment with GnRH agonists make the epiphysis more prone to slip. Considering our observations and by reviewing the literature, GnRH agonist treatment might present a risk factor for the occurrence of SCFE.

Abstract
Obesity now affects one in five children in the United States. Discrimination against overweight children begins early in childhood and becomes progressively institutionalized. Because obese children tend to be taller than their nonoverweight peers, they are apt to be viewed as more mature. The inappropriate expectations that result may have an adverse effect on their socialization. Many of the cardiovascular consequences that characterize adult-onset obesity are preceded by abnormalities that begin in childhood. Hyperlipidemia, hypertension, and abnormal glucose tolerance occur with increased frequency in obese children and adolescents. The relationship of cardiovascular risk factors to visceral fat independent of total body fat remains unclear. Sleep apnea, pseudotumor cerebri, and Blount's disease represent major sources of morbidity for which rapid and sustained weight reduction is essential. Although several periods of increased risk appear in childhood, it is not clear whether obesity with onset early in childhood carries a greater risk of adult morbidity and mortality.
Obesity is now the most prevalent nutritional disease of children and adolescents in the United States. Although obesity-associated morbidities occur more frequently in adults, significant consequences of obesity as well as the antecedents of adult disease occur in obese children and adolescents. In this review, I consider the adverse effects of obesity in children and adolescents and attempt to outline areas for future research. I refer to obesity as a body mass index greater than the 95th percentile for children of the same age and gender.

Abstract
We studied the epidemiology of physiolysis of the hip (or slipped capital femoral epiphysis) between 1946 and 1992 in 175 patients from a well-defined population. The incidence of physiolysis of the hip was calculated using the attack rate method, i.e., the sum of the annual incidences in each 1-year group. The risk of developing physiolysis was 1:998 for boys, 1:1756 for girls and 1:1267 for both sexes and did not change significantly during this period. The average age at diagnosis was 13.6 (7-17) years in boys and 12.1 (8-15) years in girls and did not change to a significant degree during this period. The difference in the boy:girl ratio (1.8:1) and in the preponderance of the left hip being affected first (64% for boys and 52% for girls) did not change significantly during this period. No significant monthly variation was found in the onset of symptoms of physiolysis of the hip.

Abstract
We evaluated the prevalence of slipped capital femoral epiphysis in the contralateral hip of 169 children who had been managed with pinning in situ and thirty who had been managed with immobilization in a spica cast. Only children who had initially been seen with a unilateral slip and had been followed for a minimum of two years or until skeletal maturity were included in the study. The average duration of follow-up was 3.6 years (range, 0.5 to 9.5 years) for the group that had been managed with a cast and 2.8 years (range, 1.0 to 8.3 years) for the group that had been managed operatively. In sixty-one (36 per cent) of the 169 patients who had had operative treatment and two (7 per cent) of the thirty who had been managed with a spica cast, a slip subsequently developed in the contralateral hip; this difference was significant (p = 0.001). On the basis of these findings, we recommend that closer attention be paid to the potential development of a slip in the contralateral hip after pinning.

Abstract
Slipped capital femoral epiphysis (SCFE) is a fairly common condition affecting older children and adolescents, and has the potential for long-term, crippling sequelae. Early recognition is the single most important controllable factor, but the diagnosis is often missed or delayed, resulting in progression of the slip. A SCFE should be suspected and promptly evaluated in any older child or adolescent presenting with a limp or complaints of hip, groin, thigh, or knee pain, especially if the patient is overweight. The diagnosis is usually made by anteroposterior and frog-leg lateral radiographs of the hips. Common errors at initial presentation include: not obtaining hip radiographs (due to either no hip pain or the lack of an impressive history and physical findings); misreading hip radiographs (the findings can be subtle); and lack of timely referral. Early involvement of and treatment by an orthopedic surgeon can greatly reduce the potential complications. We present three cases of SCFE that highlight common errors made at initial presentation, and a discussion that includes the differential diagnosis of an older child or adolescent with a painful limp.

Abstract
The records of 224 children who had a slipped capital femoral epiphysis and who had no underlying metabolic or endocrine disorder were studied retrospectively to investigate the epidemiology of bilateral slipped capital femoral epiphysis. Eighty-two (37 per cent) of the 224 children (fifty-one boys and thirty-one girls) had a bilateral slip. Sixty-four of these children were black and eighteen were white. The age at the time of the diagnosis of the first slip was 13 +/- 1.7 years (mean and standard deviation), the duration of the symptoms was 5 +/- 5.0 months, and the angle of the slip was 26 +/- 16 degrees. Obese children were younger at the time of the diagnosis of the first slip (12 +/- 1.6 compared with 13 +/- 1.6 years for the children who were not obese, p = 0.001). The diagnosis of a slipped capital femoral epiphysis was made simultaneously in both hips in forty-one children and sequentially in forty-one children. Compared with the children in whom both hips were diagnosed simultaneously, the children in whom the hips were diagnosed sequentially had had a shorter duration of the symptoms before the diagnosis of the first slip (3 +/- 2.4 compared with 7 +/- 5.9 months, p = 0.0003), were younger at the time of the diagnosis of the first slip (12 +/- 1.9 compared with 13 +/- 1.2 years, p = 0.001), and tended to be more obese (p = 0.025). In 88 per cent of the patients who had sequential slips, the second slip was diagnosed within eighteen months after the diagnosis of the first slip.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The frequency of bilateral physiolysis colli femoris was evaluated in 62 patients. At first admission, 5 patients had a bilateral slipping. Further, 9 patients had slipping diagnosed in the contralateral hip during adolescence 1-3 years after the primary operation. At the follow-up examination 22 years after the primary operation, radiographs showed bilateral sequelae of slipping in 30 of 62 patients. Of the nine slips diagnosed later during adolescence, one showed mild and two severe arthrosis. Among the 16 slips diagnosed at follow-up, mild arthrosis was found in four hips. We recommend bilateral pinning at first admission in all patients with a slipped capital femoral epiphysis.

Abstract
Growth during adolescence was analyzed in 40 children with slipped capital femoral epiphysis using the Infancy Childhood Puberty growth model. The advantage of this model is that reference values for height can be adjusted for the individual age at pubertal maturation. In both sexes an above average height was found before the onset of the pubertal growth spurt. However, the pubertal gain in height was less than normal, and at maturity the heights were only slightly above the reference mean values. Most of the children had their first hip symptoms during the period of increasing gain in height at the initial stage of the pubertal growth spurt. Both boys and girls were overweight before puberty and remained so during puberty and at maturity.

Abstract
This work is based on 532 cases of physiolysis colli femoris (PCF) in southern Sweden from 1910 through 1982. The material was analyzed epidemiologically. Subsets were used for different investigations aimed at surveying the etiology of PCF, and long-term follow-ups were conducted after various methods of treatment. Finally, the short-term results after hook-pinning, a new device, were evaluated. After radiographic examination of anatomic specimens and normal hips, a method to diagnose and grade PCF was developed. The calcar femoral was found to be of constant shape and position and was used as a landmark to which the position of the femoral head was related. The advantage of this method is that it is easy to use and it is able to determine PCF also after growthplate closure. Epidemiologic analysis of the total material revealed large changes during the 20th century. The disease is more common in males than in females, but the male predominance has decreased from about 90 per cent to about 60 per cent during the period of investigation. Mean age at onset of slipping has decreased by about 3 years in males to 12.7 years and by about 1 year in females to 11.8 years. The incidence has followed a periodic pattern with peaks approximately every 20th year. The mean incidence was 6/10,000 in boys and 3/10,000 in girls. Boys living in the country have always been at higher risk than those living in cities. They were also at higher risk of sustaining bilateral slipping. In girls, there is a seasonal variation, with a higher incidence between May and August. The etiologic investigations dealt with hereditary, mechanical, and hormonal aspects. Radiographic examination revealed PCF in about 10 per cent of the first-degree relatives of 50 consecutive patients with PCF. One third of the families had 2 or more members with PCF. This familial accumulation is much higher than shown in earlier investigations based on questionnaires or clinical reports, and higher than expected from the incidence calculations. The growth analysis using the ICP model showed in both sexes an above average body height before puberty. However, at maturity the heights were almost normal, and accordingly the pubertal gain in height was lower than normal. Both the boys and the girls were markedly overweight before puberty and remained so at maturity. The ICP model accords with what is known about hormonal regulation of growth, and the growth abnormalities indicate a disturbed hormonal growth regulation.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The degree of femoral anteversion in a group of obese adolescent children and a group of adolescent children of normal weight was determined by either magnetic resonance imaging or computerized axial tomography. Compared with the children of normal weight, the obese children showed a significantly reduced angle of femoral anteversion. Increased biomechanical forces generated across the hip joint of obese children leads to increased remodeling of the femoral neck. This may account for the association of slipped capital femoral epiphysis, reduced femoral anteversion, and obesity in the adolescent population.

Abstract
The best treatment for diseases of the hip can begin if one diagnoses the disorder as soon as possible after onset. In many cases, successful management of the disease will prevent permanent damage to the hip joint. If injury occurs to the developing hip joint, major hip surgery may be necessary in adult life.

In situ pinning and subtrochanteric osteotomy have been widely used in the operative treatment of slipped capital femoral epiphyses. A review of all operative procedures performed at Children's Orthopedic Hospital in Seattle, Washington from 1960 to 1982 was performed. In the 85 consecutive cases, there were 66 pinning procedures with a 30% incidence of pin penetration. In 18 cases of attempted pin removal, there was major difficulty in 11 (61%). In 1 3 cases of subtrochanteric osteotomy, there was a significant incidence of infection, chondrolysis, and implant complication with fair to good clinical results in 11 cases. From this series the author concludes that in situ pinning is technically difficult and that two pins are adequate. Hagie or Moore pins should not be used, because of difficult pin removal. Anterior bone graft epiphysiodesis may be the procedure of choice for slips of more than 35° to 40°. Key indexing terms: slipped capital femoral epiphysis, slipped epiphysis, internal fixation, in situ pinning, subtrochanteric osteotomy.

Abstract
The results are reported of the treatment of eight cases of acute (traumatic) slipped capital femoral epiphysis, reduced by forceful traction on the tubercle of the tibia, followed by drilling through with Kirschner wires. No necrosis of the epiphysis developed among the eight cases. In the light of these results, this therapy is recommended in cases of acute slipping of the capital femoral epiphysis. On the other hand, as far as the late complications are concerned, such as degenerative arthritis, the late results are probably no better than those obtained with other forms of treatment.
