The standard approach of diagnosing and monitoring scoliosis involves using the Cobb angle from posteroanterior (PA) radiograph. This approach has two key limitations: 1) It involves exposing the patients to ionising radiation during a period of heightened radiosensitivity. 2) The 2D x-ray image is a projection image of a 3D deformity and the Cobb angle represents only lateral rotation. 3DUS would overcome both these limitations.

We developed a 3DUS system by combining motion capture technology, a conventional 2D ultrasound scanner and bespoke software. An ex vivo experiment and a pilot clinical study were carried out to demonstrate the system's ability in identifying vertebrae landmarks and quantifying the curvature. For the ex vivo validation, a spine phantom was created by 3D-printing a segmented abdo-pelvis CT scan. The spine phantom was then scanned using 3DUS and the level of agreement in the dimensions measured using 3DUS and CT was assessed. An 11 year old female with adolescent idiopathic scoliosis (AIS) was scanned with 3DUS. The SP co-ordinates were projected on a plane of best-fit to compare the curvature angle from 3DUS with the Cobb angle from the x-ray image.

The spinous (SP), transverse processes and the laminae demonstrated high echogenicity and were easily identifiable. The difference between the spine phantom inter-SP dimension measurements made in 3DUS and CT was <2.5%. The PA x-ray of the AIS patient revealed 47° (L4-T11) and 52° (T6-T11) curves. 3DUS was able to represent the deformity in 3D revealing complex curvatures in all planes. The curvature angle from derived from 3DUS for the L4-T11 and T6-T11 curves were 132° (48°) and 125° (55°) respectively.

The results of this pilot study demonstrate 3DUS as a promising tool for imaging spine curvature

A retrospective review of patients with spinal growing rods in a single institution. Demographic data including age at first surgery, diagnosis, pre- and post-operative cobb angles from erect standardised radiographs were collected. The type of construct used i.e. spine to rib or spine to spine was noted along with the type of growing mechanism used (magnetic or cassette). Any complications were collated for each technique.

Our results include 26 patients who had growing rod insertion, 12 in the spine - spine group and 14 in rib - spine group. Pre-operative cobb angles of 71 and 78 degrees respectively with a correction to 36 and 35 degrees. Mean age at surgery was 63 months in spine to spine group and 67 months in rib to spine group. Spine to spine group had 2 proximal pull out of hooks and the rib spine group had one pull out of hook.

The correction achieved by the new technique is comparable to the spine – spine constructs. Complications are seen in both groups. The perceived benefit of the new technique is the proximal spine is not violated so there is a reduced risk of mass fusion. The canal and pedicles are not included proximally, so there will be no effect on the growing diameter of the canal. Biomechanically the construct is more robust and should allow greater control of the curve. Further follow up and analysis of this new technique is warranted.

The purpose of this study was to investigate whether patient age of 16 years and under is a valid “red flag” for back pain, by determining how often magnetic resonance imaging (MRI) investigations in these patients demonstrated significant pathology.

This was a retrospective review of cases over a five-year period (2008–12). The radiology database was interrogated to identify all patients aged 16 and under who had undergone an MRI scan of their lumbar spine for a primary complaint of low back pain. All emergency and inpatient admissions were excluded from the study. Casenotes of each of these patients were analysed for demographics, clinical features, diagnosis and outcome.

After exclusions, 98 eligible cases were identified. The age range of these patients was 2–16 years (mean age 12.63 years). The MRI scan found no abnormalities in 71.4% of cases. In the scans with positive findings, there were 8 cases of spondylolysis, 3 spondylolistheses, 9 cases of disc degeneration and 5 cases of Scheuermann's. Tumour or infection were found in only 3% of cases, (2 cases sacroilitis, 1 sacral chondroblastoma); there had been sacral or sacroiliac tenderness in each of these cases.

In keeping with other recent studies, this study shows that the diagnostic yield of MRI in patients under the age of 16 with low back pain is relatively high (28.6%). However, scan findings did not significantly alter management in the vast majority of cases (97%). Serious pathology (infection or tumour) was found in only 3% of cases. We therefore suggest that an age of 16 years or less, in isolation, should not be a “red flag” indicator for low back pain. We do however advise a lower threshold for imaging in patients presenting with sacral region pain and tenderness.

The purpose of the study was to investigate the incidence of surgical site infection following elective paediatric orthopaedic surgery.

A pro forma adopted from a pilot study was filled out preoperatively for each elective operation performed during the study period. Each patient was then followed up for six weeks postoperatively to record any SSI that developed. Data collected included patient demographics, type of operation, grade of Surgeon, type of procedure, wound length, skin preparations, use of tourniquet, any antibiotic prophylaxis and length of operation.

This study collated data on 334 operations with 410 procedural sites over a six month period. Infection were recorded in 19 sites equivalent to a SSI rate of 4.63%. None of the patients developed long-term complications.

The mean age of the participants in the study was 11 years (range 0.5 to 17 years), 57% were males and 43% were females.

The infection were detected between 1 and 38 days after surgery. The outcome was not compromised in any of the patients as none of them required long-term treatment. Statistical analysis was undertaken.

The study proves that the surgical site infection after elective paediatric orthopaedic surgery is low and serve as a bases for consenting patients for surgery.

The aim was to compare the efficacy of selective ultrasound-screening (SUSS) for developmental dysplasia of the hip (DDH) to clinical screening alone, by comparing outcomes in a contemporary group with those from a 40 year old cohort.

This was a retrospective cohort study. The department's DDH and surgical databases were used to identify all cases of DDH, and all cases of surgery for DDH during the study period (2009–13). Patients born outside our region, and teratologic cases were excluded from analysis. The Obstetric database provided the total number of live births over the five-year period. This data was used to calculate the incidence of late-diagnosis (age over 3 months) DDH and the rate of surgery for DDH in our region. These results were compared to those of a similar study from our institution published in 1977, after the introduction of universal clinical screening. Relative risk (RR) was calculated for the two groups, and analysed for statistical significance.

The incidence of late-diagnosis DDH over the recent 5-year study period was 0.66/1000 live births, compared to 0.6/1000 in the control group. The RR for late-diagnosis DDH was not significantly different between the two groups (RR 1.14, 95% CI 0.6 to 2.2). The rate of surgery for DDH was 0.86/1000, compared to 0.9/1000 live births in the control group. The RR for surgery for DDH in the current study population compared to the historic control was 0.97, but this difference was not statistically significant (95% C.I. 0.57 to 1.68; p=0.92).

Despite advances in screening for DDH over the last 40 years, neither the incidence of late diagnosis DDH, nor rates of surgery for DDH in our region have changed. Whilst previous studies have demonstrated that SUSS does not eliminate late-presenting DDH, this study suggests it confers no advantage over clinical screening alone.

The study was to ascertain if parents/carers could be effective screeners in the detection of infant hip dysplasia.

Infants have been screened for developmental hip dysplasia (DDH) since the late 1960's. The recognition of the importance for early identification of the condition has been well documented. However, the changes to the national screening programme in 2008 have reduced the surveillance of DDH following the removal of the 8 month infant hip check, leaving only the 6–8 week hip check as standard.

A self-check guide for DDH has been developed to enlist parents as screeners for the condition. The guide highlights common signs used to alert to the possibility of hip dysplasia or dislocation. The guide was disseminated by the Royal Berkshire Hospital NHS Trust between 2008 – 2013 within West Berkshire through the maternity services and Health Centres. The guide provided parents with information on classic signs associated with DDH which they were asked to check for.

Of those infants referred to our specialist clinic as a result of parental screening, 73% were “abnormal” of these 33% went on to treatment with splintage. The mean age of these infants was 5.36 months. 20% of positive findings were in infants aged 7 month or over at the time seen. None went on to open surgery. These patients represented between 5 and 10% of our overall group of DDH positive patients. If left undiagnosed, they may have gone on to late presentation of hip dislocation requiring surgery as a child or undiagnosed acetabular dysplasia and possible surgical treatment in relatively early adult life.

Therefore we concluded that given the right guidance parents/carers would be ideal screeners to assist in detecting possible later presenting DDH in their baby.

This retrospective matched cohort study tested the hypothesis that an incomplete periacetabular acetabuloplasty, as an added step to delayed open reduction, diminishes the risk of developing acetabular dysplasia.

29 hips from 23 patients with idiopathic DDH that underwent intentionally delayed open reduction and acetabuloplasty at our institution from 2003 to 2010 were matched for age at presentation and bilaterality to historic controls. These were 29 hips from 26 patients, treated with open reduction alone from 1989 to 2003. Residual dysplasia treated with pelvic osteotomy, AVN grade II-IV, and rate of re-intervention were the outcome measures.

The mean ages at diagnosis and at surgery were 8.62 weeks and 12.97 months, respectively. At latest follow-up, 27 hips in the acetabuloplasty group and 22 in the open reduction alone group had satisfactory radiographic outcome (Severin class Ia, Ib or II) (p=0.16). 18 of the 58 hips (31.0%) had AVN, 7 (24.14%) in the case group and 11(37.93%) in the control group. Further surgery was required in 15 of the 29 hips in the open reduction alone group. These included 2 revision of open reductions, 5 pelvic osteotomies, 3 varus derotation osteotomies, and 5 apo or epiphysiodesis whilst only one patient in the acetabuloplasty group required a medial screw epiphysiodesis for late lateral growth arrest. There is a positive association between the need for further surgery and open reductions alone: the odds ratio is 14.00 and the 95% confidence interval (1.97, 99.63), p=0.0017. The five hips in the open reduction alone group that required a pelvic osteotomy were intervened at an average of 31.45 (±9.07) months.

The addition of an incomplete periacetabular periacetabuloplasty to all hips undergoing open reduction eliminated residual acetabular dysplasia in this cohort whilst it does not appear to have deleterious effects, as evidenced by the similar Severin and McKay scores.

The aim was to assess the long-term impact of humeral and forearm rodding on functional ability, grip strength, joint range of motion and angular deformity in children with osteogenesis imperfecta.

A retrospective chart review was conducted on 57 children with osteogenesis imperfecta who underwent humeral rodding or forearm rodding at our institution between 1996 and 2013. Functional ability was assessed using the self-care and mobility domains of the Pediatric Evaluation and Disability Inventory (PEDI). Grip strength was measured using a dynamometer and joint range of motion with a goniometer. Deformity was measured on radiographs of the humerus or forearm. Outcomes were assessed pre-operatively and every year post-operatively. Differences between pre-operative and 1-year post-operative outcomes were compared using paired T-tests. In 44 patients with a minimum of 2 years follow-up, outcome measures at 1-year post-surgery were compared to those at the latest clinic visit (mean follow-up = 8.0 years).

Humeral and forearm rodding resulted in a significant improvement in PEDI self-care score (mean change =5.75, p=0.028 for the humerus, mean change = 6.77, p=0.0017 for the forearm) and mobility score (mean change =3.59, p=0.008 for the humerus, mean change =7.21, p=0.020 for the forearm) at 1 year post-surgery. Grip strength improved following forearm rodding (mean change = +6.13N, p=0.015) but not humeral rodding. Joint range of movement improved following humeral rodding but not forearm rodding. There was a significant improvement in radiographic angular deformity of the forearm and humerus following surgery (p<0.0001). Over 80% of improvements were maintained in the long-term.

Humeral and forearm rodding in children with osteogenesis imperfecta leads to long-term improvement in functional ability and angular deformity.

This study aimed to define the rates of lower limb angular correction using temporary hemiepiphysiodesis in differing skeletal pathologies.

A retrospective review of 61 children (36M:25F) with angular deformities about the knee who underwent 8-plate hemiepiphysiodesis (mean age 10.8y) was undertaken. The children were divided into 9 groups based on their underlying pathology (lower limb hypoplasia, Blount's disease, skeletal dysplasia, rickets, metabolic disease, acquired growth disturbance, vascular malformation, steroid use and complex genetic disorders). Radiographic measurements of each limb segment was undertaken using the TraumaCad® digital templating software based on standing long-leg radiographs - mechanical lateral distal femoral angle (mLDFA) and mechanical medial proximal tibial angle (mMPTA). The rate of correction of each parameter was calculated as a function of the time lapse between the operation date and first radiographic evidence of full correction of the mechanical axis (zone 1).

A total of 144 limb segments (80 distal femoral, 64 proximal tibial physes) were analysed. 62.5% of children had mechanical axes outside the knee joint at the time of operation; 63.2% achieved full correction. The rate of angular correction at the distal femur (mLDFA) was quickest in those with acquired growth disturbance (1.15°/month), complex genetic disorders (1.12°/month) and rickets (0.93°/month). It was slowest in those with vascular malformation (0.40°/month), lower extremity hypoplasia (0.44°/month) and metabolic disease (0.49°/month). At the proximal tibia, mMPTA correction was quickest in those with acquired growth disturbance (0.77°/month) and skeletal dysplasia (0.57°/month); whilst being slowest in those with metabolic disease (0.22°/month) and Blount's disease (0.29°/month).

The rate of angular correction about the knee varies with the underlying pathology with correction rates varying up to 3-fold. This study demonstrated the differential rate of correction of angular deformities in children with different skeletal pathologies, which would help guide the timing of hemiepiphysiodesis.

The purpose of the study was to identify risk factors that are associated with re-displacement of the hip after surgical reconstruction in cerebral palsy.

Retrospective review of children with cerebral palsy who had hip reconstruction with proximal femoral varus derotation osteotomy (VDRO) and Dega-type pelvic osteotomy, between 2005–2012, at a UK and European institution, was performed. Patient demographics, GMFCS, clinical and radiological outcome were assessed as well as the presence of pelvic obliquity and significant scoliosis (Cobb angle > 10 degrees). Redisplacement was defined as Reimer's Migration Index (MI) >30% at final follow-up. Logistic regression analysis was used to assess which factors were predictive of redisplacement and adjusted for clustered variables (α = 0.05).

Eighty hips were identified in 61 patients. The mean age at surgery was 8.8 years (± 3.3). Mean MI pre-op was 68% (± 23%) and post-op was 8% (± 12%). At a mean follow-up, of 3.2 years (± 2.0), 23 hips had a MI >30%. Of these; five were symptomatic, and one had required a salvage procedure. Metalwork removal was undertaken in 14 hips. Logistic regression demonstrated that the pre-operative MI and the percentage of acute correction were significant predictors of re-displacement. If the pre-operative MI was greater than 65 percent, the odds ratio (OR) for redisplacement was 5.99 (p = 0.04). If correction of the MI was less than 90% of the pre-operative MI, the OR for re-displacement was 4.6 (p = 0.03). Age at the time of surgery, GMFCS, pelvic obliquity and scoliosis were not predictive of re-displacement.

These results, firstly, highlight the importance of hip surveillance in children with cerebral palsy to allow timely intervention to ensure adequate radiological outcomes. Secondly, as in developmental hip dysplasia, full concentric reduction is essential to reduce the risk of re-displacement, with its associated clinical consequences.

Ambulating children with bilateral spastic cerebral palsy (BSCP) demonstrate atypical posture and gait due to abnormal muscle and skeletal growth when compared to typically–developing (TD) children. Normal postural alignment in standing facilitates many of the tasks of daily living because it allows a stable base of support without requiring significant muscular effort. Similarly, increasing gait abnormality is associated with poorer functional capacity. Our aims were to compare the standing posture of TD children and children with BSCP using the Standing Profile Score and identify if any abnormality in standing is correlated with abnormality in walking in children with BSCP using the Gait Profile Score index.

We retrospectively compared 44 typically-developing children to 74 age-matched children with BSCP (GMFCS I & II). We performed 3D Gait Analysis during long-standing (10seconds) and in gait after application of 16 retro-reflective markers on anatomical landmarks of the lower limb and pelvis. Analysis of all kinematics was performed for movements in the sagittal, coronal and axial planes. The Gait Profile score (GPS) is a validated index of overall gait pathology. The Standing Profile Score (SPS) was developed using the same calculations for GPS but during static trials.

A significant correlation was observed between the Standing Profile Score (SPS) and Gait Profile Score (GPS) in children with BSCP (p<0.001). Significant differences were exhibited in GPS between the two groups, across all parameters, except the pelvic obliquity (p<0.05). A significant positive correlation existed for hip rotation in both groups, however the correlations observed at hip flexion and ankle dorsiflexion were significantly greater in the BSCP group compare to the TD group (p<0.01).

We have shown that posture during gait (GPS) is predictable from standing posture (SPS) in patients with BSCP. This biomechanical relationship can aid surgical decision-making.

A goal attainment scale (GAS) was used to evaluate outcomes of surgical and non-surgical interventions to improve gait in children with diplegic cerebral palsy (CP).

Personal goals were recorded pre-intervention from children and/or their carers attending the Edinburgh Gait Laboratory since 2012. Twenty children underwent orthopaedic surgery (Group 1) and 25 children underwent a non-orthopaedic intervention (Group 2). Patients were excluded if the intervention was <9 months before the study period. Post-operatively children and/or their carers were contacted by telephone to complete the mGAS questionnaire, rating the achievement of goals on a 5-point scale. The majority of goals related to structure and function and were similar between groups, with goals relating to stability and lower limb structure most frequently recorded. Attaining an improvement in pain was stated more frequently by Group 1 children. The GAS formula was used to transform the composite GAS into a standardised measure (T-score) for each patient. A t-test was used to determine if the change in T-score was significantly different from 0, i.e. no change. Both groups on average achieved their goals (mean change in T-score for Group 2 11.1, vs 21.1 for Group 1). The difference between these two means was significant (p = 0.012). Additionally 16 children had undergone a follow-up gait analysis, but the relationship between the change in Gait Profile Score and GAS, assessed by Pearson's correlation coefficient was statistically insignificant.

Both surgical and non-surgical interventions enabled children to achieve their goals, although Group 1 reported higher achievement. GAS reflect patients’ aspirations and may be as relevant as post-intervention kinematic or kinetic outcomes.

The disadvantages of hip spica casts following hip surgery for cerebral palsy include fractures, plaster sores, soiling and general inconvenience. In this series, 56 hips in 31 children aged 4 to 16 years (mean 8) were treated for hip displacement in keeping with the recommendations of others (eg Miller et al 1997) between 2005 and 2008 by one consultant. There were 29 open reductions for a Reimer's migration index (RMI) greater than 50%. A blade plate was used for the femoral osteotomy, and an acetabuloplasty was performed for 22 hips. No casting or immobilisation of any sort was used. The average length of stay was 5 days. The results at 5 the year follow-up were chosen so that all patients were at the same stage. The average RMI pre-operatively for displaced hips was 76.9 +/− 21.3. At follow-up it was 18.8 +/− 19.7. 18 patients had pain prior to hip surgery; 6 had pain during follow-up, and 4 of these responded to removal of metal; and one required a proximal femoral resection. There were 3 complications: one re-dislocation in the immediate post-operative period, one mal-union because the blade plate cut out; and one of the three walking children fractured below the blade plate 2 ½ months after surgery. There were no infections.

The radiographic and clinical outcomes of hip reconstruction without hip spica immobilisation are good, reproducible and long-lasting. The child may be nursed free post-operatively and discharged in his or her own chair. As a result of studying these patients, since 2009 we have introduced locking plates for better fixation, and pre- and post-operative Paediatric Pain Profiles and CPCHILD questionnaires.

The aim was to assess contemporary management of slipped capital femoral epiphysis (SCFE) by surveying members of the British Society of Children's Orthopaedic Surgery (BSCOS).

A questionnaire with 5 case vignettes was used. Two questions examined the timing of surgery for an acute unstable SCFE in a child presenting at 6 hours and at 48 hours after start of symptoms. Two further questions explored the preferred method of fixation in mild and severe stable SCFE. The final question examined the management of the contralateral normal hip. Responses were entered into an Excel spreadsheet and the data w analysed using a chi-squared test.

The response rate was 56% (110/196). 88.2% (97/110) responded that if a child presented with an acute unstable SCFE within 6 hours, they would treat it within 24 hours of presentation, compared with 40.9% (45/110) for one presenting 48 hours after the onset of symptoms (P<0.0001). 52.6% (58/110) of surveyed BSCOS members would offer surgery for an unstable SCFE between 1 and 7 days after onset of symptoms. Single screw fixation in situ was advocated by 96.4% (106/110) and 70.9% (78/110) while corrective osteotomy was preferred by 1.8% (2/110) and 26.4% (29/110) of respondents for the mild and the severe stable slips respectively (P<0.0001). Surgeons preferring osteotomy are more likely to perform an intracapsular technique. Prophylactic fixation of the contralateral normal hip was performed by 27.3% (30/110) of participants.

There are significant differences in opinions between BSCOS members as to the optimal management of SCFE in children. This reflects the variable recommendations and quality in the current scientific literature. Further research is therefore required to determine best practice and enable consensus to be reached.

The unwell child with an acutely irritable hip poses a diagnostic dilemma. Recent studies indicate that pericapsular myositis may be at least as common as joint infection in the septic child. MRI might therefore be a critical first step to avoid unnecessary hip drainage surgery in the septic child with hip symptoms.

We reviewed our own experience with MR imaging in this setting.

We searched our PACS system to retrieve MRI scans performed for children with suspected hip sepsis from August 2008 to August 2014 using the following terms: hip, septic arthritis, osteomyelitis, mysositis, abscess, femur, acetabulum. 56 cases fulfilled inclusion criteria that included acute presentation with hip symptoms and 2 or more Kocher criteria for septic arthritis. Recent unsuccessful hip washout was not a contra-indication.

56 patients presented with acute infection around the hip. 47 (84%) had MRI scans before any surgical intervention and 9 (16%) had scans promptly following unsatisfactory hip washout with failure to improve.

20 (36%) were found to have pericapsular myositis. In this group, the infection commonly involved the iliopsoas (4), gluteal (4), piriformis (5) or obturator (7) muscles. 15 (27%) children had proximal femoral or acetabular osteomyelitis and 8 (14%) were diagnosed with septic arthritis. The 13 (23%) remaining scans did not show infection around the hip.

This study confirms a high rate of extracapsular foci in septic children presenting with hip irritability. Less than 20% had actual septic arthritis in this series. While drainage of a septic joint should never be delayed in the face of a large joint effusion with debris on US, there is a clear role for MRI scanning in the acute setting when the diagnosis is less certain.

Paediatric distal radial and forearm fractures account for 37.4% of all fractures in children. We present our 2.5-year results of a novel safe approach to the treatment of simple distal radial and diaphyseal fractures using intranasal diamorphine and entonox in a designated fracture reduction room in the emergency department.

All simple fractures of the distal radius and forearm admitted to our ED between March 2012 and August 2014 that could be reduced using simple manipulation techniques were included in this study. These included angulated diaphyseal fractures of the forearm, angulated metaphyseal fractures of the distal radius and Salter Harris types I and II without significant shortening. All children included were given intranasal diamorphine as well as entonox. The orthopaedic registrar on call performed all reductions.

100 children had their distal radius or forearm fracture reduced in the emergency department using entonox and diamorphine analgesia and had a same day discharge. Average age was 10 years (range 2.20–16.37 years). No complications were reported regarding the use of the analgesia and all children and parents were pleased with their treatment not requiring a hospital admission. The mean initial dorsal angulation of all fracture types was 28.05° degrees (23.91–32.23 95% CI) which was reduced to 7.03° (5.11–8.95 95% CI) post manipulation. There were 9 cases lost to follow up. Two cases lost the initial reduction of the fracture on subsequent clinic follow up and underwent internal fixation in theatre.

The use of entonox and intranasal diamorphine is a safe, effective treatment of providing adequate analgesia for children with distal radial and forearm fractures to allow manipulation of displaced dorsally angulated fractures in the emergency department. By facilitating a same day discharge, over £45,000 was saved using this safe method of treatment.

The aim of this study was to determine the effectiveness of intra-operative tranexamic acid in children with osteogenesis imperfecta, who have been shown to have increased bleeding tendency, in deformity correction surgery.

We retrospectively reviewed all cases of lower limb intramedullary rodding in patients with osteogenesis imperfecta treated in our unit from 2000–2013 in whom a pre and post- operative full blood count was available (n=69). Case notes were reviewed and patients were grouped according to the use of tranexamic acid. Peri-operative change in haemoglobin (Hb), haematocrit (HCT) and requirement for blood transfusion was assessed.

Of 69 operations performed, 62.3% were in female patients, 78.3% were femoral, and 43.5% were bilateral cases (19 femur, 11 tibia). In the non-tranexamic acid group there was a mean drop in Hb of 28.9 g/L (range 0–62), mean HCT drop of 8.8 (range 2.2–19.4) and 3 patients required red cell transfusion. In the tranexamic acid group there was a mean Hb drop of 22.5 g/L (range 1–49), mean HCT drop of 7.35 (range −0.8–16.7) and one patient required red cell transfusion. There was a significant decrease in Hb drop (p=0.0287) in the tranexamic acid group.

Tranexamic acid seems to decrease the drop in haemoglobin during lower limb intramedullary rodding in patients with osteogenesis imperfecta, with little associated risk. Protocols should be established for future use a further review undertaken.

A femoral fracture in an adolescent is a significant injury. It is generally agreed that operative fixation is the treatment of choice and rigid intramedullary nailing is a surgical treatment option. We present on experience of treating adolescent femoral fractures using a lateral entry intramedullary nail.

We reviewed 15 femoral fractures in 13 children who we treated in our unit between 2011 and 2014. Two patients had bilateral fractures (non-simultaneous). Data collected included patient demographics, mechanism of injury, type of fracture, associated injuries, size of nail, time to unite and complications.

The mean age of the patients at time of surgery was 12 years (range 10–15). There were 7 male and 6 female. 10 fractures were caused by a fall whilst 5 were due to road traffic collisions (RTC). 8 fractures involved the middle third, 2 of theses were open fractures and were caused by a RTC. The remaining 7 involved the proximal third of the femur. The mean time to radiological union was 3.4 months (range 2.5–5) in 14 fractures. One patient had a delayed union that required bone grafting and united fully at 7.5 months post injury. The only other complications were a broken proximal locking screw in one patient and an undisplaced femoral neck fracture in another patient. These complications did not compromise the outcome. No patients had infection or developed avascular necroses at the latest follow up.

Intramedullary nailing of adolescent femoral fractures using the lateral entry point is safe and effective

The aim was to assess the effect of caudal block on patients who have had proximal femoral &/or pelvic osteotomy compared to patients who have had epidural anaesthesia with regards to pain relief and hospital stay.

We looked at two patient cohorts; epidural & caudal pain relief in aforementioned procedures. Interrogation of our clinical database (WinDip, BlueSpeir&clinical notes) identified 57 patients: 33 proximal femoral osteotomy, 13 pelvic osteotomy and 11 combined(25 Males 32 Females), aged 1–18 years-old between 2012–2014, in two institutions. A database of demographics, operative indications, associated procedures, analgesia and type of anaesthesia was constructed in relation to daily pain score and length of hospital stay. 39 patients had epidural anaesthesia, and 18 had caudal block. Cerebral palsy with unstable hips was the commonest indication(21), followed by dysplastic hip(10), Perthes disease(8) and other causes(18). The Face, Legs, Activity, Cry, Consolability(FLACC) scale was used to assess pain.

Length of hospital stay in caudal block patients was 3.1 days(1–9), in epidural anaesthesia patients stay was 4.46 days(2–13). Paediatrics high dependency unit after an epidural was needed in 20(Average stay 3.4 days) compared to 1 who received caudal block. Caudal block FLACC pain score in the first 36 hours was 1.23(0–4) compared to 0.18(0–2) in patients who had an epidural.

Caudal block is associated with less hospital stay and fewer admissions to the high dependency unit, it also provides adequate pain relief post osteotomies when compared to epidural, therefore could be performed at units lacking epidural facilities. A change in related practice however should be cautious and supported by further studies.
