Introduction. Derotation osteotomies are commonly performed in paediatric orthopaedic and limb reconstruction practice. The purpose of this study was to determine whether the use of a digital inclinometer significantly improves the accuracy in attaining the desired correction. Materials & Methods. We designed an electronic survey regarding derotation femoral osteotomy (DFO) including methods of intra-operative angular correction assessment and acceptable margins of error for correction. This was distributed to 28 paediatric orthopaedic surgeons in our region. A DFO model was created, using an anatomic sawbone with foam covering. 8 orthopaedic surgeons each performed two 30-degree DFOs, one using K-wires and visual estimation (VE), and the other using a Digital Inclinometer (DI). Two radiologists reported pre and post procedure rotational profile CT scans to assess the achieved rotational correction. Results. There was a 68% response rate to the survey. The most popular methods of estimating intra-operative correction were reported to be K-wires and rotation marks on bone. The majority of respondents reported that a 6–10 degree margin of error was acceptable for a 30-degree derotation. This was therefore set as the upper limit for acceptable error margin in the simulation study. The mean error in rotation in the VE group of simulated DFO was 19.7 degrees, with error>5 degrees and error>10 degrees in 7 (88%) and 6 (75%) cases respectively. Mean error in DI group was 3.1 degrees, with error>5 degrees in 1 case (13%). Conclusions. Our results show that the compared to conventional techniques, the use of an inclinometer significantly improves the accuracy of femoral de-rotation and significantly reduces the incidence of unacceptable errors in correction. We would suggest that digital inclinometers be used to assess intra-operative correction during derotation osteotomies

The Gartland extension-type supracondylar humerus fracture is the most common elbow fracture in the paediatric population. Depending on fracture classification, treatment options range from nonoperative treatment such as taping, splinting or casting to operative treatments such as closed reduction and percutaneous pinning or open reduction. Classification variability between surgeons is a potential contributing factor to existing controversy over nonoperative versus operative treatment for Type II supracondylar fractures. The purpose of this study was to investigate levels of agreement in classification of extension-type supracondylar humerus fractures using the Gartland classification system. A retrospective chart review was conducted on patients aged 2–12 years who had sustained an extension-type supracondylar fracture and received either operative or nonoperative treatment at a tertiary children's hospital. De-identified baseline anteroposterior (AP) and lateral plain elbow radiographs were provided along with a brief summary of the modified Gartland classification system to surgeons across Canada, United States, Australia, United Kingdom and India. Each surgeon was blinded to patient treatment and asked to classify the fractures as Type I, IIA, IIB or III according to the classification system provided. A total of 21 paediatric orthopaedic surgeons completed one round of classification, of these, 15 completed a second round using the same radiographs in a reshuffled order. Kappa values using pre-determined weighted kappa coefficients were calculated to assess interobserver and intraobserver levels of agreement. In total, 60 sets of baseline elbow radiographs were provided to survey respondents. Interobserver agreement for classification based on the Gartland criteria between surgeons was a mean of 0.68, 95% CI [0.67, 0.69] (0.61–0.80 considered substantial agreement). Intraobserver agreement was a mean of 0.80 [0.75, 0.84]. (0.61–0.80 substantial agreement, 0.81–1 almost perfect agreement). Radiographic classification of extension-type supracondylar humerus fractures at baseline demonstrated substantial agreement both between and within surgeon raters. Levels of agreement are substantial enough to suggest that classification variability is not a major contributing factor to variability in treatment between surgeons for Type II supracondylar fractures. Further research is needed to compare patient outcomes between nonoperative and operative treatment for these fractures, so as to establish consensus and a standardized treatment protocol for optimal patient care across centres

Dynamic 2D sonography of the infant hip is a commonly used clinical procedure for developmental dysplasia of the hip (DDH) screening. It however has been found to be unreliable with some studies reporting associated misdiagnosis rates of up to 29%. In a recent systematic review, Charlton et al. examined dynamic ultrasound (US) screening for hip instability in the first six weeks after birth and found current best practices for such early screening techniques to be divergent between international institutions in terms of clinical scanning protocols. Such protocols include: the appropriate scanning plane and US probe position (e.g. coronal, transverse, lateral, anterior), DDH diagnostic metrics (e.g. femoral head coverage, alpha angle), appropriate patient age when scanning, and follow up procedures. To improve reliability of diagnosis and to help in standardizing diagnosis across different raters and health-centers, we propose an automated method for dynamically assessing hip instability using 3D US. 38 infant hips from 19 patients were scanned with B-mode 3D US by a paediatric orthopaedic surgeon and two technologists from the radiology department at a paediatric tertiary care centre. To quantify hip assessment, we proposed the use of femoral head coverage variability (ΔFHC3D) within 3D US volumes collected during a sequence of US scans (one at rest, and another with posterior stress applied to the joint as maneuvered during a dynamic assessment). We used phase symmetry image features to localize the ilium's vertical cortex and a random forest classifier to identify the location of the femoral head. The proposed ΔFHC3D provided good repeatability with an average test-retest ICC measure of 0.70 (95% confidence interval: 0.35 to 0.87, F(21,21) = 7.738, p<.001). The mean difference of ΔFHC3D measurements was 0.61% with a SD of 4.05%. Since the observed changes in ΔFHC3D start near 0% and range up to about 18% from stable to mildly unstable hips in this cohort, the mean difference and standard deviation of ΔFHC3D measurements observed suggest that the proposed metric and technique likely have sufficient resolution and repeatability to quantify differences in hip laxity. The long-term significance of this approach to evaluating dynamic assessments may lie in increasing early diagnostic accuracy in order to prevent dysplasia remaining undetected prior to manifesting itself in early adulthood joint disease

Developmental Dysplasia of the Hip (DDH) is the most common orthopaedic disorder in newborns. Whilst the Pavlik harness is one of the most frequently used treatments for DDH, there is immense variability in treatment parameters reported in the literature and in clinical practice, leading to difficulties in standardising teaching and comparing outcomes. In the absence of definitive quantitative evidence for the optimal Pavlik harness management strategy in DDH, we addressed this problem by scientifically obtaining international expert-based consensus on the same. An initial list of items relevant to Pavlik harness treatment was derived by systematic review of the literature according to PRISMA criteria and reviewed by two expert clinicians in DDH management. Delphi methodology was used to guide serial rounds of surveying and feedback to content matter experts from the International Hip Dysplasia Institute (IHDI), a collaborative group of paediatric orthopaedic surgeons with expertise in the management of DDH. Rounds of surveying continued in the same manner until consensus was reached. Importance ratings were derived from each round of surveying by calculating median score responses on the 5-point Likert scale for each item. Items requiring clarification or those with a median score of below 4 (“agree”) were modified as needed prior to each subsequent round. Consensus was considered reached when 90% or more of the items had an interquartile range (IQR) of ≤ 1. This value indicates low sample deviation and is accepted as having achieved consensus. This was followed by a corroboration of face validity to derive the final set of management principles. The literature search and expert review identified an initial list of 66 items in 8 categories relevant to Pavlik harness management. Four rounds of structured surveying were required to reach consensus. Following a final round of face validity, a definitive list of 33 items in 8 categories met consensus by the experts. These items were tabulated and presented as “General Principles of Pavlik Harness Treatment for DDH” and “Pavlik Harness Treatment by Severity of Hip Dysplasia”. Furthermore, highly contentious items were identified as important future areas of study and will be discussed. We have developed a comprehensive set of principles derived by expert consensus to assist clinicians, and for use as a teaching resource, in the non-operative management of DDH using the Pavlik harness. We have gained consensus on both the general principles of Pavlik harness treatment as well as the detailed treatment of hip subtypes seen across the spectrum of pathology of DDH. Furthermore, this study has also served to generate a list of the most controversial areas in the non-operative management of DDH which should be considered high priority for future study to further refine and optimise the outcomes of children with developmental hip dysplasia

Avascular necrosis (AVN) of the femoral head is a potentially devastating complication of treatment for developmental dysplasia of the hip (DDH). AVN most commonly occurs following operative management by closed (CR) or open reduction (OR). This occurrence has frequently been examined in single centre, retrospective studies, however, little high-level evidence exists to provide insight on potential risk factors. The purpose of this observational, prospective multi-centre study was to identify predictors of AVN following operatively-managed DDH. A multi-centre, prospective database of infants diagnosed with DDH from 0–18 months was analyzed for patients treated by CR and/or OR. At minimum one year follow-up, the incidence of AVN (Salter criteria) was determined from AP pelvis radiographs via blinded assessment and consensus discussion between three senior paediatric orthopaedic surgeons. Patient demographics, clinical exam findings and radiographic data were assessed for potential predictors of AVN. A total of 139 hips in 125 patients (102 female, 23 male) underwent CR/OR at a median age of 10.4 months (range 0.7–27.9). AVN was identified in 37 cases (26.6% incidence) at a median 23 months post-surgery. Univariate logistic regression analysis comparing AVN and no AVN groups identified sex, age at diagnosis, age at surgery, pre-surgery IHDI grade and time between diagnosis and surgery as potential predictive factors. Specifically, male sex (OR 2.21 [0.87,5.72]), IHDI grade IV, and older age at diagnosis (7.4 vs. 9.5 months) and surgery (10.2 vs. 13.6 months) were associated with development of AVN. Likewise, increased time between diagnosis and surgery (2.9 vs. 5.5 months) was also associated with a higher incidence. No association was found with surgery type (CR vs. OR), pre-surgery acetabular index or surgical hip. Development of AVN occurred in 26.6% of hips undergoing CR or OR at a median 23 months post-surgery. Male sex, older age at diagnosis and surgery, dislocation severity and increased time between diagnosis and surgery were associated with AVN. Longer-term follow-up and larger numbers will be required to confirm these findings. Early outcomes from this prospective patient cohort suggest that AVN is an important complication of operative management for DDH, and appears to occur at a comparable rate whether the reduction is performed open or closed. Male patients may be more susceptible to developing AVN and merits further exploration. Potential predictive factors of older age and length of time between diagnosis and surgery emphasize the importance of early detection and treatment to minimize complications and optimize outcomes

Musculoskeletal ultrasound (MSK-US) can have many uses for orthopaedic surgeons, such as assisting in clinical diagnosis for muscle, tendon and ligament injuries, providing direct guidance for joint injections, or assessing the adequacy of a reduction in the emergency department. However, proficiency in sonography is not a requirement for Royal College certification, and orthopaedic trainees are rarely exposed to this modality. The purpose of this project was to assess the usefulness in clinical education of a newly implemented MSK-US course in an orthopaedic surgery program. A MSK-US course for orthopaedic surgery residents was developed by an interdisciplinary team involving a paediatric orthopaedic surgeon, an emergency physician with a fellowship in point-of-care ultrasonography, and an orthopaedic surgery resident. Online videos were created to be viewed by residents prior to a half-day long practical course. The online portion covered the basics of ultrasonography, as well as the normal and abnormal appearance of musculoskeletal structures, while the practical portion applied those principles to the examination, injection, and aspiration of joints, and ultrasound-guided fracture reduction. An online survey covering the level of training of the resident and their previous use of ultrasound (total hours) was filled by the participants prior to the course. Resident's knowledge acquisition was measured with a written pre-course, same-day post-course and six-month follow-up tests. Residents were also scored on a practical shoulder examination immediately after the course and at six-month follow-up. An online survey was also sent to evaluate residents' satisfaction with different aspects of the course (NAS). Change in test scores were calculated using an ANOVA and a Wilcoxon signed-rank test. Ten orthopaedic surgery residents underwent the MSK-US curriculum. Pre-course interest to MSK-US was moderate (65%) and prior exposure was low (1.5 hours mean total experience). MSK-US has been previously mostly observed in the emergency department and sports orthopaedic clinic. Satisfaction with the online curriculum, hands-on practice session and general quality of the course were high (8.78, 8.70 and 8.60/10 respectively). Written test scores improved significantly from 50.7 ± 17% to 84 ± 10.7% immediately after the course (p < 0 .001) and suffered no significant drop at six months (score 75 ± 8.7%, p=0.303). Average post-course practical exam score was 78.8 ± 3.1% and decreased to 66.2 ± 11.3% at six months (p=0.012). Residents significantly improved their subjective comfort level with all aspects of ultrasound use at six months (p=0.007–0.018) but did not significantly increase clinical usage frequency. A MSK-US curriculum was successfully developed and implemented using an interdisciplinary approach. The course was rated high quality and succeeded in improving the residents' knowledge, skills, and comfort with MSK-US. This improvement was maintained at six months on the written test, but did not result in higher frequency of use by the residents

Congenital talipes equinovarus (CTEV) is a complex three-dimensional deformity with an incidence of 1–3 per 1000 live births. The Ponseti method is widely accepted and practiced, giving reliably good long-term results. There are a number of studies showing the benefits of a physiotherapy led Ponseti service with outcomes similar to a consultant led service. We present the first prospective randomised series comparing a physiotherapy led Ponseti service with a standard orthopaedic surgeon led series. 16 infants with bilateral CTEV were randomised into two groups. Each infant had one foot treated by a physiotherapist and the other foot treated by an orthopaedic surgeon using the Ponseti technique. Both groups had a premanipulation Pirani score of 5.5. All patients were followed up for a minimum of 12 months and the results demonstrated no significant difference in the post-treatment Pirani scores (p=0.77) and no significant difference in the success rate the Ponseti technique (p=1.00). This study is the first of its kind and demonstrates the value of a physiotherapy led Ponseti service in the management of CTEV. Although overall supervision by a paediatric orthopaedic surgeon is still necessary, this service will allow the surgeon to spend more time dealing with more complex problems

The management of the dysplastic hip represents a clinical and a technical challenge to the paediatric orthopaedic surgeon. There is a great deal of variation in the degree and direction of acetabular dysplasia. Preoperative planning in the dysplastic hip is still largely based on plain radiographs. However, these plain films are a 2D projection of a 3D structure and measurement is prone to inaccuracy as a result. Hip arthrography is used in an attempt to analyse the 3D morphology of the hip. However, this still employs a 2D projection of a 3D structure and in addition has the risk of general anaesthesia and infection. Geometrical analysis based on multiplanar imaging with CT scans has been shown to reduce analysis variability. We present a system for morphological analysis and preoperative of the paediatric hip using this model. Our system can be used to determine the most appropriate osteotomy based on morphology. This system should increase the accuracy of preoperative planning and reduce the need for arthrography

Early detection of Developmental Dysplasia of the Hip (DDH), and treatment, may prevent the need for surgical correction following late presentation. Neonatal examination, and ultrasound screening of at risk groups, does not detect all cases. Most neonates treated in the Intensive Care Unit (NICU) have abdominal radiographs performed during their stay. These include the hips but DDH is not routinely looked for. 50 neonatal abdominal films (five from patients who subsequently were found to have DDH, 45 from patients without this condition) were randomly shown to three paediatric orthopaedic surgeons and three paediatric radiologists on two separate occasions. Each was asked whether they would refer the patient for further investigation. An overall sensitivity of 25.5% (Range 0–60%) and specificity of 93.2% (Range 87–97%) was found with a positive predictive value (PPV) of 14.0% (Range 0–37%) and negative predictive value (NPV)of 96.3% (Range 95–98%). Although the low sensitivity and PPV make interpretation of these films a poor way to diagnose DDH, the high specificity and NPV suggest that they may be used as a prompt to further investigation. Therefore, we propose that DDH should be looked for on these films and, where there is radiological suspicion, ultrasound examination should be advised

There is currently no standardised complication grading classification routinely used for paediatric orthopaedic surgical procedures. The Clavien-Dindo classification used in general surgery was modified and validated in 2011 by Sink et al. and has been used regularly to classify complications following hip preservation surgery. The aim of this study was to adapt and validate Sink et al.'s modification of the Clavien-Dindo classification system for grading complications following surgical interventions of the upper and lower extremities and spine in paediatric orthopaedic patients. Sink et al.'s modification of the Clavien-Dindo classification system was further modified for paediatric orthopaedic procedures. The modified grading scheme was based on the treatment required to treat the complication and the long term morbidity of the complication. Grade I complications do not require deviation from standard treatment. Grade II complications deviate from the normal post-operative course and require outpatient treatment. Grade III complications require investigations, re-admission or re-operation. Grade IV complications are limb or life threatening or have a potential for permanent disability (IVa: with no long term disability and IVb: with long-term disability). Grade V complications result in death. Forty-five complication scenarios were developed. Seven paediatric orthopaedic surgeons were trained to use the modified system and they each graded the scenarios on two occasions. The scenarios were presented in a different random order each time they were graded. Fleiss' and Cohen's k statistics were performed to test for inter-rater and intra-rater reliabilities, respectively. The overall Fleiss' k value for inter-rater reliability was 0.772 (95% CI, 0.744–0.799). The weighted k was 0.765 (95% CI, 0.703–0.826) for Grade I, 0.692 (95% CI, 0.630–0.753) for Grade II, 0.733 (95% CI, 0.671–0.795) for Grade III, 0.657(95% CI, 0.595–0.719) for Grade IVa, 0.769 (95% CI, 0.707–0.83) for Grade IVb and 1.000 for Grade V (p value <0.001). The Cohen's k value for intra-rater reliability was 0.918 (95% CI, 0.887–0.947). These tests show that the adapted classification system has high inter- and intra-rater reliabilities for grading complications following paediatric orthopaedic surgery. Given the high intra- and inter-rater reliability and simplicity of this system, adoption of this grading scheme as a standard of reporting complications in paediatric orthopaedic surgery could be considered. Since the evaluation of surgical outcomes should include the ability to reliably grade surgical complications, this reproducible, reliable system to assess paediatric surgical complications will be a valuable tool for improving surgical practices and patient outcomes

Background. The gold standard of care of clubfoot is the Ponseti method of serial manipulation and casting, followed by percutaneous tendo-achilles tenotomy. In our setting, registrars work in district hospitals where they run Ponseti clubfoot clinics with little or no specialist supervision. They use the Pirani score to serially assess improvement of the deformity during casting and to determine whether the foot is ready for tenotomy. Purpose of Study. To test the inter-observer reliability of the Pirani score, and whether it can be used by non-specialist doctors running Ponseti clubfoot clinics. Methods. Ethics permission was obtained from our institution. This is a prospective study where patients under the age of one year with idiopathic clubfoot were recruited from clubfoot clinics at our institution, over a period of four months. Following a training session using the original description of the score, each foot was independently assessed using the Pirani score by two paediatric orthopaedic surgeons, two orthopaedic registrars and two medical officers. The inter-observer reliability was assessed using the Fixed-marginal Kappa statistic and Percentage agreement. The first 15 feet were used as a learning curve, and hence excluded from final analysis. Results. 73 feet in 37 patients with idiopathic clubfoot (25 boys, 12 girls) under the age of 1 year were included in the study. The Kappa statistic and percentage agreement for the six variables of the Pirani score were determined. Whilst the overall agreement was determined by the Kappa statistic to be slight to fair, the two consultants were found to have a higher inter-observer reliability than the registrars and medical officers. Conclusion. Our results conflict with previously published studies in that the inter-observer reliability of the Pirani score was poor. In addition, we feel that this score cannot be reliably used by non-specialist doctors running Ponseti clubfoot clinics. NO DISCLOSURES

Referral patterns in spine clinic of young patients with suspected scoliosis is suboptimal with 19% of late referrals and 42% of inappropriate referrals. Patients' triage and prioritisation in spine clinic is a strategy to ensure that health care allocation is done according to the level of health needs, favoring effective management and efficient use of health care resources use. The objective of the study is to elaborate a model for triage and prioritisation of young patients in spine clinic based on expert consensus and literature on best practices. This projects was structured in three parts: 1)We documented best evidence. We conducted a review of empirical studies evaluating triage and prioritisation initiatives in order to identify key components for intervention success. 2)We elaborate a model of health care delivery with the professionals of a local paediatric spine clinic. In this model, the triage and prioritisation algorithm was developed from list of potential factors (demographics, signs and perceived symptoms, provisional diagnoses and known co-morbidities, results of preliminary physical examination and radiological findings) that was submitted to five paediatric orthopaedic surgeons for rating according to their potential relevance to orient prioritisation decisions. 3) We compared the professionals' model of health care delivery to the literature synthesis in order to propose the best model. Seven key components of triage and prioritisation systems were identified: centralised review of referral requests, list of consensual objectives criteria for triage, fast track evaluation of urgent cases, selection of cases for management at point of triage, cases prioritisation to main consultant, multidisciplinary evaluation and alternatives pathways. The consensual decision algorithm confirmed that cases who should be seen in priority are immature patients presenting with a significant trunk deformity. In addition, presence of persisting neurological symptoms, severe incapacitating pain or night pain, as well as abnormal scan or MRI findings were considered as urgent/PI priority. Cases characteristics for evaluation by nurse practitioners as well as alternative pathways of management were defined. Acceptability, compatibility, clinical relevance and discriminant capacity of the new model of health care delivery were satisfactorily demonstrated. Consensus was easily reached between the five respondents on factors supporting decisions to prioritise patients in spine clinic for suspected spinal deformity. Refinements to the initially proposed model according the identified key features from the literature, led to a final model of health care delivery that is evidence-base, feasible and coherent with the local context. Future implementation of this model should facilitate timely and appropriate health care delivery and best use of health care resources according to patients' needs

Background and Aims:. In 2009 a combined clinic was formed by the orthopaedic Surgeons and Developmental Paediatricians in our hospital. The aim was to help improve the assessment and management of patients with Cerebral Palsy. Included in the assessment team, are the paediatric orthopaedic surgeons, the developmental paediatricians, physiotherapists and occupational therapists. Our aim was to audit the patients presenting to this clinic over a 15 month period to look at the demographic data, clinical severity and decisions taken for these patients. Methods:. We looked at patients seen in the clinic from January 2013 to March 2014. We recorded the age, gender and primary caregiver. We also recorded the reason for referral. Clinically we wanted to know the type and distribution of the CP, GMFCS score, attainment of milestones and type of schooling. We recorded underlying aetiologies and HIV status of the patients. Finally the access the patients had to physiotherapy and Occupational therapy. Results:. We saw 41 patients in total with 18 males and 23 females. The ages ranged from 5 months to 9 years (mean 4.9 years). 36 of 41 (88%) had spastic CP, 2 (5%) dystonic, 1 (2%) mixed and 2 (5%) were not recorded. Diplegic and hemiplegic predominated with 15 (37%) and 14 (34%) respectively, there were 6 (15%) quadriplegics, 1 double hemiplegic and 5 were not recorded. 13 (31%) of patients had birth asphyxia as an aetiology, 13 (31%) had brain anomalies, 9 (22%) were premature babies, the remaining 16% comprised HIV, post natal sepsis and injury. 38 (93%) were cared for by at least one parent and the remaining 3 (7%) were cared for by a grandparent. 39 (95%) had access to physiotherapy and 30 (73%) had access to occupational therapy. 21 (51%) had no access to appropriate schooling. 9 (22%) were known to be HIV positive. The recommended orthopaedic interventions were continued physiotherapy for 17 (41%) and botox in 22(54%). Discussion:. The combined clinic has highlighted the diverse nature of cerebral palsy and the challenges facing our patients. It is an invaluable tool in the goal directed management of complex cases

The consequences of the complications associated with the management of slipped upper femoral epiphysis are a major source of disability in young adults. Whilst the management of chondrolysis, avascular necrosis or malunion of the femoral neck is usually undertaken by paediatric orthopaedic surgeons the initial management of SUFE in many regions is as part of an adult trauma service. This retrospective audit assessed the outcome of the management of SUFE in one such health region in which treatment occurred at three sites by a number of surgeons of varying experience, during the period July 1994 to June 2004. The aim was to compare our outcomes with those published and to identify whether our service should be altered as a consequence. The case notes and x-rays as recorded in theatre records were retrieved. Of the 64 cases that were treated during this period adequate records for 60 patients were available. Of these 60 patients there were 7 bilateral cases. Fixation in all 67 cases was by a single cannulated screw. In the 53 unilateral cases 17 underwent prophylactic pinning, the remaining 36 remained under observation. Of these nine patients presented with subsequent slips, eight of which were unstable and two had slip angles greater than 60° in which one developed avascular necrosis. Four other cases of avascular necrosis were observed (incidence 6%). Chondrolysis occurred in one patient with persistent pin penetration. In the remaining 73 cannulated screws used for stabilisation and 17 for prophylactic fixation no complications were observed. The complication rates observed in this series are within those accepted in the literature. The high incidence of subsequent slips and the attendant severity of these when compared with the relative safety of contemporary cannulated screw fixation has led us to recommend prophylactic pinning in our region

Aim. To assess the results of Castles procedure performed at our hospital compared with those available in literature. Introduction. Fifteen patients (19 hips) with severe disability and hip subluxation/dislocation underwent proximal femoral resection arthroplasty (Castles procedure) over a 10 year period under the care of 2 paediatric orthopaedic surgeons. We conducted a retrospective study of case series whether the surgery (Castles procedure) improved the pain levels, sitting tolerance, ability to use commode/nappy change, ease of dressing and the carers overall satisfaction with the procedure. Patients and methods. We reviewed the surgeons' and theatre log books for patients' details. We then contacted the patients' parents/guardian by telephone, and using a set questionnaire, we obtained valuable information on how successful the surgery had been in their opinion. Results. Out of 15 patients, 14 had severe cerebral palsy and one had severe brain damage secondary to trauma. The average age at surgery was 4.23 years (range 6–118 months). 14 patients obtained significant pain relief but one patient remained the same. 13 patients were found to have both sitting tolerance and sleeping improved. One patient suffered a pressure sore which has healed with conservative management. 2 patients had additional trimming procedure for heterotopic ossification excision. Apart from this there were no cases of skin breakdown. All patients found the bathing and dressing change was easier post operatively. 2 carers required extra help as the limbs were floppy but not a major issue compared to the overall benefits from the Castles procedure. Overall 13 carers were very satisfied with the procedure, two were satisfied and none were unsatisfied. Conclusion. Our telephone survey shows the Castles procedure was a successful salvage procedure for painful dislocated hips in non-ambulatory patients with severe disability

Developmental dysplasia of the hip (DDH) is the commonest musculoskeletal condition diagnosed in neonates. Two previous studies showed no statistical advantage with the addition of ultrasound to clinical screening. In the UK, the Standing Medical Advisory Committee (SMAC) (1969) recommended clinical examination at birth and at 6 weeks. The Newborn Infant Physical Examination (NIPE) (2008) guidelines in addition advised ultrasound scanning for clinically unstable hips or for those with risk factors (breech presentation or family history). We compared SMAC and NIPE in the two main hospitals of the East Lancashire Hospitals NHS Trust: Burnley General Hospital (BGH) and the Royal Blackburn Hospital (RBH), respectively. Our outcome measure was the number of irreducible hip dislocations over a two year period (2007–2008). The records of the lead Paediatric Orthopaedic Surgeon were used to identify all cases of irreducible hip dislocations born in 2007 and 2008. Maternity records provided information on birth statistics. Syndromal cases were excluded from further analysis. BGH had 5382 live births and 7 irreducible hip dislocations (incidence 1.3/1000 births). 4/7 met SMAC recommendations and 6/7 met NIPE guidelines. 2/7 had equivocal clinical examinations at birth. 13 children were referred to the clinic with unstable hips (2.42/1000 births). RBH had 7899 total births and 3 irreducible hip dislocations (incidence 0.38/1000 births). 2/3 met NIPE guidance and 1/3 met SMAC recommendations. 33 were referred to the clinic with unstable hips (4.18/1000 births). The difference in the numbers of irreducible hips did not reach statistical significance (p=0.12). This study found no statistically significant advantage with the addition of selective ‘at risk’ ultrasound screening to clinical screening alone. Confounding factors in this study included the age of referral of cases to clinic and the numbers of cases referred as primary instability. These findings are in keeping with two previous studies in Norway

Purpose. Pediatric orthopaedic surgeons encounter referrals from primary care practitioners and pediatricians that are benign in nature or within accepted limitations for physiological musculoskeletal variance. These referrals are believed to be secondary to insufficient pediatric musculoskeletal expertise and consume already limited pediatric orthopaedic resources. To date, our annual CME course dedicated to pediatric musculoskeletal medicine is the only one of its kind in Canada. It includes didactic teaching as well as a clinic of unnecessary referrals in which participants examine patients and receive feedback from consultants. The purpose of this study was to evaluate the impact of a pediatric musculoskeletal CME course on the quality of local outpatient referrals over a four year period. Method. Retrospective chart reviews were performed to evaluate outpatient referrals at a tertiary orthopaedic center over an eight month period prior to the commencement of an annual CME course (2006–2007) and three years following its initiation (2010). 1041 consecutive referrals from the first time period and 1124 consecutive referrals from the second time period were collected. Referrals for normal conditions within physiological tolerance were identified based on the final clinical diagnosis by the consultant orthopaedic surgeon and the scheduled follow up. Results. 872 referrals from the first time period and 1006 referrals from the second time period were provided by primary care practitioners and pediatricians. Prior to the CME course, 27.7% of referrals were for physiological conditions. These referrals were most often associated with specific benign diagnoses: torsional variation (88%) and flexible flatfoot (45%). Three years following the induction of the CME course, referrals for physiological conditions from family physicians decreased by 20.1%. Conclusion. Results from this study suggest that a pediatric musculoskeletal CME course designed for family physicians and pediatricans is an effective method for reducing unnecessary local pediatric orthopaedic referrals. We advocate that additional CME initiatives based on our annual course be implemented in communities across Canada in order to improve patient care and optimize the outpatient referral process
