Background:. Paley et al has developed the multiplier method for predicting leg length. It is a tool that is used clinically to predict leg length discrepancy. The method is also a way of comparing different populations, to identify differences in growth trajectory. This has been done by identifying the differing multipliers for girls and boys. However it has not been used to identify trends in populations separated by time. Tanner showed that in the first half of the twentieth century girls went from an average age of menarche of 15 in 1900, to 13 in 1970, how this has affected growth trajectory over the last 50 years has not been studied. Purpose:. The multiplier method is based on data collected in the 1950's by Anderson and Green, we aim to assess whether there has been a change in growth trajectory between this historical cohort and a contemporary European based cohort. Methods:. The Avon Longitudinal Study of Parents and Children of the 90s (ALSPAC) is a longitudinal cohort study of children recruited antenatally, and followed prospectively. Assessment of sub ischial leg length was made on clinical measurements. There were up to 8 measurements per patient, 2311 girls with a final age at assessment of greater than 15 years and 123 males with a final age of assessment of greater than 16 years were assessed. We used the multiplier method to assess the predicted final leg length and compared this with the actual leg length. Result:. There was no difference between the multiplier in girls, in the contemporary cohort and the historical cohort. The average age of menarche in the contemporary group was 12.7. In boys the data is limited, due to later growth and it is not possible to draw comparisons from this group. Conclusion:. This data provides good evidence that there has not been a significant change in growth trajectory in girls over the last 50 years. Significance:. Implications on the confidence with which we can use the multiplier method in this population

Aims. The management of completely displaced fractures of the distal radius in children remains controversial. This study evaluates the outcomes of surgical and non-surgical management of ‘off-ended’ fractures in children with at least two years of potential growth remaining. Methods. A total of 34 boys and 22 girls aged 0 to ten years with a closed, completely displaced metaphyseal distal radial fracture presented between 1 November 2015 and 1 January 2020. After 2018, children aged ten or under were offered treatment in a straight plaster or manipulation under anaesthesia with Kirschner (K-)wire stabilization. Case notes and radiographs were reviewed to evaluate outcomes. In all, 16 underwent treatment in a straight cast and 40 had manipulation under anaesthesia, including 37 stabilized with K-wires. Results. Of the children treated in a straight cast, all were discharged with good range of mo (ROM). Five children were discharged at six to 12 weeks with no functional limitations at six-month follow-up. A total of 11 children were discharged between 12 and 50 weeks with a normal ROM and radiological evidence of remodelling. One child had a subsequent diaphyseal fracture proximal to the original injury four years after the initial fracture. Re-displacement with angulation greater than 10° occurred for 17 children who had manipulation under anaesthesia. Four had a visible cosmetic deformity at discharge and nine had restriction of movement, with four requiring physiotherapy. One child developed over- granulation at the pin site and one wire became buried, resulting in a difficult retrieval in clinic. No children had pin site infections. Conclusion. Nonoperative management of completely displaced distal radial fractures in appropriately selected cases results in excellent outcomes without exposing the child to the risks of surgery. This study suggests that nonoperative management of these injuries is a viable and potentially underused strategy. Cite this article: Bone Joint J 2021;103-B(5):902–907

Introduction:. Paley et al has developed a multiplier method for calculating both leg length and total height. In the development of this algorithm, they evaluated the effect of factors including bone age and sex. They established that sex had a significant impact, but adjusting for bone age did not improve accuracy. Bone age and menarche have been shown to improve other height prediction models. Purpose:. We used a large prospective cohort to evaluate if the multiplier is independent of physiological age using menarche as a proxy. Methods:. Using the ALSPAC dataset we determined the accuracy of the Paley multiplier for predicting total height and leg length, and assed weather if the date of first menses increased the accuracy of the multiplier. Female patients over the age of 8, with documented final height and final sub-ishial leg length over the age of 15 and a date of first menses were evaluated. Predicted final height was compared with actual final height at all data points. Results:. There were 28332 data points in 3062 girls prior to skeletal maturity in the total height cohort and 8395 data points in 2300 girls in the leg length cohort. When age was corrected using the difference in age at onset of menarche from average, the accuracy of multiplier decreased for both measurements. When a correction of 50% was used, there was an improvement in the accuracy of multiplier predictions, reducing the average error by up to 24%. Conclusions:. Previous studies have failed to demonstrate that the accuracy of the multiplier is improved when adjusted for bone age. We have used the date of first menses as a proxy for bone age and established that making a 50% correction for physiological age improves the accuracy of this method. Significance:. This will potentially allow more accurate prediction of leg length discrepancy, and total height in girls with early menarche

We have attempted to describe the epidemiology of femoral fractures in children in the West Midlands region of the National Health Service in England. Our source of data was the Regional Hospital Episode Statistics database for the years 1991-2 to 2001-2. Cases were defined as emergency hospital admissions in patients aged under 16 years, with a diagnostic code of femoral fractures in any field, and resident in the West Midlands. Between 1991-2 and 2001-2, 3272 children aged under 16 years with femoral fractures were admitted to hospital. The crude incidence during this period decreased from 0.33 to 0.22 femoral fractures/1000/year. Those caused by traffic accidents decreased by 43%, and by falls by 29%. The peak age-gender-specific incidence (0.91/1000/year) was in two-year-old boys, and this was 50% higher than in the next highest age-gender group. In the first year of life, the incidence in boys and girls was the same. Thereafter the rate in boys exceeded that in girls, varying from 1.6 times at 11 years to 4.7 times at 14 years. Falls accounted for 49% of the fractures, varying from 77% in one-year-olds to 26% in eight-year-old children. Traffic accidents were responsible for 26% of fractures varying from 55% in ten-year-old to 2% in one-year-old children. Maltreatment was recorded in 1.3% of all cases, and in 8.5% of children under one year. Twice as many fractures were seen in May to August than in January (winter). The rates of fractures were associated with deprivation for all age-gender groups. Fractures of the shaft accounted for 58% of all fractures, varying from 70% in three-year-old to 34% in 13-year-old children. Our findings show that there has been a decrease in the incidence of femoral fractures during the 1990s and early 2000s. Two-year-old boys had twice the rate than any other single-year age-gender group. More deprived areas had much higher rates which suggests the potential for greater prevention. A relatively low rate of maltreatment was recorded compared with that in some other studies

INTRODUCTION. Spinal injuries in children are rare and account for a low proportion of all childhood injuries. Because of higher mobility and elasticity of the spine and a lower body mass in children, spinal injuries are not frequent and represent only 2 to 5 % of all spinal injuries. MATERIAL. All patients from birth to the completed 18th year of age treated in our departments between 1996 and 2005 were included in this study. The patients, evaluated in three age categories (0–9, 10–14, 15–18), were allocated to two groups according to the method of treatment used (conservative or surgical). The information on patients treated conservatively was drawn from medical records; the surgically treated patients were invited for a check-up. RESULTS. During 1996 through 2005, we treated a total of 15 646 patients with injury to the skeleton, aged 0 to 18 years. The spine was affected in 571 cases, which is 3.6 %. We used conservative treatment in 528 (92.5 %) and surgery in 43 (7.5 %) children. The group of patients treated conservatively consisted of 292 boys (55. 3 %) and 236 girls (44.7 %); of these 219 (41.5 %) were in the 0–9 year category, 251 (47.5 %) were between 10 and 14 years and 58 (11 %) were 15 to 18 years old (mean age 10.2 years). The most frequent cause of injury was a fall (277; 52.2 %), then sports activity or games (86; 16.3 %), car accidents (34; 6.4 %) and diving accidents (30; 5.7 %). Pedestrians were injured on 25 occasions (4.7 %) and other causes in 76 patients (14.4 %). Thoracic spine was most frequent (340; 64.4 %), multi-segment injury in 124 patients (23.5 %). The TL spine was affected in 22 patients (4.2 %), and lumbar vertebrae were injured in 28 patients (5.3 %). Injury to the cervical spine, both upper and lower, was least frequent, including 4 (0.8 %) and 10 (1.9 %) patients, respectively. None showed neurological deficit. The surgically treated group included 29 (67.4 %) boys and 14 (32.6 %) girls; two (4.7 %) children were between 0 and 9 years, nine (20.9 %) between 10 and 14 years, and 32 (74.7 %) between 15 and 18 years (mean age 15.1 years). The frequent causes of injury were car accidents and falls in 21 (48.8 %) and 14 (32.6 %) children, respectively. Other causes were infrequent. The upper cervical spine was operated on in five (11.6 %), lower cervical spine in eight (18.6 %), thoracic spine in 13 (30.2 %), TL spine in five (11.6 %) and lumbar vertebrae in 12 (27.9 %) patients. Thirty-six (83.7 %) patients had fractures, five had dislocated fractures (11.6 %) and two (4.7 %) had a dislocation. Neurological deficit was recorded in nine (20.9 %). CONCLUSIONS. Childhood spinal injuries account for only 2 to 5 % of all spinal injuries and for 3.6 % of all skeletal injuries in children. The cervical spine is affected most often in younger children, while the thoracolumbar spine in older children. Multi-segment injuries are typical in the childhood spine, particularly in smaller children. Typically, children show SCIWORA and a more rapid improvement of neurological deficit than adults. Conservative treatment is preferred; surgery before 12 years of age is strictly individual, while after 12 years therapy is similar to that used in adults

Between 1998 and 2002, 37 neuropathies in 32 patients with a displaced supracondylar fracture of the humerus who were referred to a nerve injury unit were identified. There were 19 boys and 13 girls with a mean age of 7.9 years (3.6 to 11.3). A retrospective review of these injuries was performed. The ulnar nerve was injured in 19, the median nerve in ten and the radial nerve in eight cases. Fourteen neuropathies were noted at the initial presentation and 23 were diagnosed after treatment of the fracture. After referral, exploration of the nerve was planned for 13 patients. Surgery was later cancelled in three because of clinical recovery. Six patients underwent neurolysis alone. Excision of neuroma and nerve grafting were performed in four. At follow-up, 26 patients had an excellent, five a good and one a fair outcome

Twenty-three patients with thirty hips of slipped capital femoral epiphysis were treated in our department, KK Women's and Children's Hospital, Singapore between 1997 and 2005. Except one patient lost of follow-up, twenty-four SCFEs with more than 2 years (25 to 73 months, average 38.5 months) follow-up were reviewed. This study is to evaluate the effectiveness and outcome of our protocol: Russell traction followed by gentle manipulative reduction with a single screw fixation & spica cast immobilization (for acute-on-chronic cases with unstable and reducible SCFE). In this series, there were 13 boys & 5 girls, mean age 12 year old ranging from 10 to 14 years. Among them 7 were Chinese, 6 Malays & 5 Indians. There were 12 unilateral cases (8 on the left & 4 right, 67%) & 6 bilateral cases (33%), including 2 patients found contralateral SCFE subsequently 1 year postoperatively. Acute-on-chronic SCFE were 16 & chronic SCFE 8. 16 were Grate I & 8 Grate II. Russell traction was on preoperatively with an average of 6 days. Gentle manipulative reduction under general anesthesia was performed in 20 SCFEs (12 GI & 8 GII) and 17 of them were successful. Fixation with a single screw was used for all cases except one hip with 2 screws. Average follow-up was 38.5 months. Good results achieved. All patient were symptom free with good function. No complications of AVN, chondrolysis, screw loosening and reslipping of the affective hips. Our protocol of management for SCFE has been largely successful in term of manipulative reduction and fixation

A series of 26 children was referred to our specialist unit with a ‘pink pulseless hand’ following a supracondylar fracture of the distal humerus after a mean period of three months (4 days to 12 months) except for one referred after almost three years. They were followed up for a mean of 15.5 years (4 to 26). The neurovascular injuries and resulting impairment in function and salvage procedures were recorded. The mean age at presentation was 8.6 years (2 to 12). There were eight girls and 18 boys. Only four of the 26 patients had undergone immediate surgical exploration before referral and three of these four had a satisfactory outcome. In one child the brachial artery had been explored unsuccessfully at 48 hours. As a result 23 of the 26 children presented with established ischaemic contracture of the forearm and hand. Two responded to conservative stretching. In the remaining 21 the antecubital fossa was explored. The aim of surgery was to try to improve the function of the hand and forearm, to assess nerve, vessel and muscle damage, to relieve entrapment and to minimise future disturbance of growth. Based on our results we recommend urgent exploration of the vessels and nerves in a child with a ‘pink pulseless hand’, not relieved by reduction of a supracondylar fracture of the distal humerus and presenting with persistent and increasing pain suggestive of a deepening nerve lesion and critical ischaemia

Nine children sustained a second fracture of the distal humerus after union of an ipsilateral supracondylar fracture which had healed with cubitus varus. There were eight boys and one girl with a mean age of five years (1 to 8) at the time of the second fracture which occurred at a mean of 1.5 years after the first. In all patients, the second fracture was an epiphyseal injury of the distal humerus, either associated with a fracture of the lateral metaphysis below the site of the previous supracondylar fracture, or a fracture-separation of the entire distal humeral epiphysis. This suggests that the physis and epiphysis tend to be more subject to injury than the metaphysis of the distal humerus in children who have had a previous supracondylar fracture with varus malunion

Introduction. Sternoclavicular dislocations are well-known adult injuries. The same traumatism causes growth-plate fracture of the medial clavicle in children and young adults. At this location, the emergence of the secondary ossification center and its bony fusion are late. We report the results of 20 cases hospitalized in the Toulouse University Hospital Center that were treated surgically. Materials & Methods. 20 patients were treated between 1993 and 2007, 17 boys and 3 girls, 16 years old (6–20). The traumatism was always violent (rugby 75%). Two physeal fractures were anteriorly displaced, and 18 posteriorly. The follow-up is 64 month (8–174). Clinical, radiographic and therapeutic characteristics were assessed. The long-term results were analysed with: an algo-functional scale (Oxford shoulder score), the subjective Constant score, a functional disability scale (Shoulder simple test), a quality of life scale (DASH), and global indicators (SANE and global satisfaction). Results. all the patients were symptomatic before surgery: pains, oedema and partial functional impotence. Only 2 dysphagia, 1 dyspnea and 1 venous circulation alteration were observed. The first clinical and radiological examination, before CT scan, didn't diagnose the injury in 8 cases. The CT scan were realized for all the patients: it diagnosed the physeal fracture and showed 4 cases of vascular or respiratory compressions. There were 5 attempts of closed reduction, without success: all the patients were surgically-treated. The open reduction were completed by pinning (12 cases) or cerclage with absorbable suture (3 cases). Per-operatory findings lead to realize costo-clavicular repair plasties with the sub-clavicular muscle (3 cases) and/or capsular-ligamentous-perosteal selective plasties (13 cases). Two cases of broken Kirschner wires were noticed, without migration. Functional outcomes are largely good or excellent: STT 11,74/12 (10–12)–OSS 12,95/60 (12–19)–DASH 2,07/100 (0–17,6)–SANE 93,16% (60–100). Discussion and Conclusion. we present the largest case series in the literature. CT scanner is the essential element of the diagnostic process and may allow the distinction between true sterno-clavicular dislocation and displaced physeal fractures. This distinction is difficult at younger ages and is facilitated by the progression of ossification. Very good results were obtained, but classical pitfalls of treatment were found: instability after closed reduction, broken K-wires, recurrent anterior instability, inesthetic scars

Introduction. The aim of the treatment of children with early onset scoliosis is controlling growth of the spine. Whatever the etiology, early progressive deformations require multiple stages of surgery usually performed every 6–12 months. One have to be reckoned with complications requiring additional surgical intervention. Objective. The aim of the study is to present a new method of surgical treatment of early onset scoliosis involving the implantation of specially constructed implants to allow three dimensional correction of spinal deformity with a preserved capacity to continue the growth of spine without distraction staged operations followed by final spondylodesis in mature spine. Material. The clinical material consists of homogeneous group of patients: 8 girls and a one boy aged 6 to 14 years (mean age = 9 years). The estimated group four children had a single-curve, four children had a double-curve, while one child was affected by congenital kyphosis. The follow up ranged from 2 to 17 months (mean = 13.5 months). Method. Efficacy of spinal deformity correction using a “growing implants” was estimated by Cobb andgle measurement of the curvature 1/before the operation, 2/after surgery and 3/follow up. Results. During surgery, all patients obtained a large correction of curvature ranging from 50% to 100% (on average −70%). The degree of correction was directly dependent on the size of the initial deformation of 62 to 120 ° (average 77 °). During the entire period of observation in four children we have not identified the loss of correction or fits within the limits of measurement error. In one child thirty degree-loss correction stemmed from too selective implantation of the implants. During additional surgery the stabilization was extended to the extra two motor segments witch resulting in full correction. In one patient, due to rapid growth, rods were needed to be replaced for longer, because of the risk of pulling out from the lower screws. In one case we observed further correction during follow up. Conclusions. Using the method we obtained a very good correction in the first stage of treatment. Maintenance of correction does not require any intermediate staged operating procedures. Patients do not require corrective brace. Using “growing implants” in the early onset scoliosis one avoid complications peculiar to current growth-sparing procedures. These patients would have had 15 lengthening procedures after their initial correction if treated by conventional growing rod methods

Aims

The aim of this study was to explore the patients’ experience of recovery from open fracture of the lower limb in acute care.

Paediatric fractures are common and can cause significant morbidity. Socioeconomic deprivation is associated with an increased incidence of fractures in both adults and children, but little is known about the epidemiology of paediatric fractures. In this study we investigated the effect of social deprivation on the epidemiology of paediatric fractures.

We compiled a prospective database of all fractures in children aged < 16 years presenting to the study centre. Demographics, type of fracture, mode of injury and postcode were recorded. Socioeconomic status quintiles were assigned for each child using the Scottish Index for Multiple Deprivation (SIMD).

We found a correlation between increasing deprivation and the incidence of fractures (r = 1.00, p < 0.001). In the most deprived group the incidence was 2420/100 000/yr, which diminished to 1775/100 000/yr in the least deprived group.

The most deprived children were more likely to suffer a fracture as a result of a fall (odds ratio (OR) = 1.5, p < 0.0001), blunt trauma (OR = 1.5, p = 0.026) or a road traffic accident (OR = 2.7, p < 0.0001) than the least deprived.

These findings have important implications for public health and preventative measures.

The aim of this study was to investigate the epidemiology of fractures of the distal radius in the Swedish population and to review the methods used to treat them between 2005 and 2010.

The study population consisted of every patient in Sweden who was diagnosed with a fracture of the wrist between 1 January 2005 and 31 December 2010. There were 177 893 fractures of the distal radius. The incidence rate in the total population was 32 per 10 000 person-years. The mean age of the patients was 44 years (0 to 104). The proportion of fractures treated operatively increased from 16% in 2005 to 20% in 2010. The incidence rate for plate fixation in the adult population increased 3.61 fold. The incidence rate for external fixation decreased by 67%. The change was greatest in the 50 years to 74 years age group.

In Sweden, there is an increasing tendency to operate on fractures of the distal radius. The previously reported increase in the use of plating is confirmed: it has increased more than threefold over a five-year period.

Corticosteroid use has been implicated in the development of osteonecrosis of the femoral head (ONFH). The exact mechanism and predisposing factors such as age, gender, dosage, type and combination of steroid treatment remain controversial. Between March and July 2003, a total of 539 patients with severe acute respiratory syndrome (SARS) were treated with five different types of steroid. There were 129 men (24%) and 410 women (76%) with a mean age of 33.7 years (21 to 59). Routine screening was undertaken with radiographs, MRI and/or CT to determine the incidence of ONFH.

Of the 129 male patients with SARS, 51 (39.5%) were diagnosed as suffering from ONFH, compared with only 79 of 410 female patients (19.3%). The incidence of ONFH in the patients aged between 20 and 49 years was much higher than that of the group aged between 50 and 59 years (25.9% (127 of 491) versus 6.3% (3 of 48); p = 0.018). The incidence of ONFH in patients receiving one type of steroid was 12.5% (21 of 168), which was much lower than patients receiving two different types (28.6%; 96 of 336) or three different types of steroid (37.1%; 13 of 35).

Although supracondylar fracture is a very common elbow injury in childhood, there is no consensus on the timing of surgery, approach for open reduction and positioning of fixation wires. We report our ten-year experience between 1993 and 2003 in 291 children.

Most fractures (285; 98%) were extension injuries, mainly Gartland types II (73; 25%) and III (163; 56%). Six (2%) were open fractures and a neurovascular deficit was seen in 12 (4%) patients. Of the 236 children (81%) who required an operation, 181 (77%) were taken to theatre on the day of admission. Most (177; 75%) of the operations were performed by specialist registrars. Fixation was by crossed Kirschner wires in 158 of 186 (85%) patients and open reduction was necessary in 52 (22%).

A post-operative neurological deficit was seen in nine patients (4%) and three (1%) required exploration of the ulnar nerve. Only 22 (4%) patients had a long-term deformity, nine (3%) from malreduction and three (1%) because of growth arrest, but corrective surgery for functional limitation was required in only three (1%) patients.

We retrospectively reviewed 183 children with a simple fracture of the distal radius, with or without fracture of the ulna, treated by closed reduction and cast immobilisation. The fracture redisplaced after an initial, acceptable closed reduction in 46 (25%). Complete initial displacement was identified as the most important factor leading to redisplacement. Other contributing factors were the presence of an ipsilateral distal ulnar fracture, and the reduction of completely displaced fractures under deep sedation or local haematoma block. We recommend that completely displaced fractures of the distal radius in children should be reduced under general anaesthesia, and fixed by primary percutaneous Kirschner wires even when a satisfactory closed reduction has been achieved.

A relationship between social deprivation and the incidence of fracture in adolescents has not previously been shown. We have used a complete fracture database to identify adolescents who sustained fractures in 2000. The 2001 Scottish census was used to obtain age-specific population and deprivation data according to the Carstairs score. Regression analysis determined the relationship between the incidence of fractures and social deprivation.

We analysed 1574 adolescents with fractures (1083 male, 491 female). The incidence of fractures in this group was 21.8 per thousand (31.0 male, 13.1 female). Social deprivation predicted the incidence in adolescent males and females. The incidence of fractures of the proximal upper limb and distal radius in females was overwhelmingly influenced by socioeconomic factors. Males of 15 to 20 years of age were more likely to sustain fractures of the hand and carpus if they lived in economically depressed neighbourhoods.

Several techniques are available for the treatment of displaced fractures of the neck of the radius in children. We report our experience in 14 children treated by indirect reduction and fixation using an elastic stable intramedullary nail. The patients were followed up for a mean of 28 months. One developed asymptomatic avascular necrosis. The rest had excellent results. One had a neuropraxia of the posterior interosseous nerve, which recovered within six weeks. We advocate elastic stable intramedullary nailing for the closed reduction and fixation of these fractures in children.
