Purpose

To determine the impact of sonographic information on surgeons' diagnostic thinking and decision-making in the management of infants with clinically suspicious hip dysplasia.

Four experienced consultant surgeons examined 66 hips referred for possible hip dysplasia and reported for each hip (i) the confidence level (visual analogue scale 0-100) about the diagnosis of this hip, and (ii) how they would manage the hip. Each infant was referred to ultrasound and the same surgeon repeated the rating with the sonographic information available. We determined the efficiency in diagnostic thinking and calculated the mean gain in diagnostic confidence that was provided by the sonographic information. We also determined the therapeutic efficacy, ie the impact of ultrasound information on surgeons’ management plans.

The ultrasound led to a change in diagnosis in 34/66 (52%) hips. However, the management plan only changed in 21/66 (32%) hips. The mean gain in reported diagnostic confidence was 19.37 (95% CI = 17.27, 21.47). If the treatment plan did not change, there still was a gain in diagnostic confidence but this gain was small with a mean value of 8 (95% CI = 5.29, 10.70). However, if the ultrasound led to a change of the treatment plan, the mean gain in diagnostic confidence was much higher with 46 (95% CI = 30.53, 60.79). The difference was -37.67 (P < 0.0001). Ultrasound was most useful (mean gain >30) in hips demonstrating limited abduction or a positive Galeazzi sign.

We have reviewed the complication rate over a ten year period for removal of screws placed for slipped capital femoral epiphysis (SCFE) and have surveyed the views of orthopaedic surgeons with an adult hip practice in Scotland on leaving the metalwork in situ. Whilst screw removal is favoured by many orthopaedic surgeons, a recent review of the literature reported that the complication rate for removal of implants placed for SCFE was 34%.

Between 1998 and 2007 84 patients had insertion of screws for SCFE. Of these 54 patients had screws removed, 51 of these records were available. The median duration between insertion and removal of screws was 2 yrs 7 months. Of the 51 children, overall five (9.8%) had complications - three (5.9%) major and two (3.9%) minor. Two screws could not be removed; one patient sustained a fracture after screw removal and two developed an infection.

We assessed the attitudes of adult hip surgeons on this topic using an electronic questionnaire which was completed by 29 out of 40 recipients. 78.6% of respondents support routine removal and 21.4% favour leaving the screw permanently in place. 82.2% had needed to remove metalwork from a hip requiring arthroplasty in a patient whose metalwork was inserted during childhood; and described their experience of this including the complications encountered.

We have identified a lower complication rate following screw removal inserted for SCFE than in published series. Most adult hip surgeons support routine removal once the physis is closed but studies regarding the long-term outcome of retained orthopaedic implants are needed since even with this lower complication rate the question of routine removal remains unclear.

Aims. The aim of this study was to explore parents and young people’s experience of having a medial epicondyle fracture, and their thoughts about the uncertainty regarding the optimal treatment. Methods. Families were identified after being invited to participate in a randomized controlled trial of surgery or no surgery for displaced medial epicondyle fractures of the humerus in children. A purposeful sample of 25 parents (22 females) and five young people (three females, mean age 11 years (7 to 14)) from 15 UK hospitals were interviewed a mean of 39 days (14 to 78) from injury. Qualitative interviews were informed by phenomenology and themes identified to convey participants’ experience. Results. The results identify parents’ desire to do the best for their child expressed through two themes: 1) ‘uncertainty’ (being uncertain about the best treatment option); and 2) ‘facilitating recovery’ (sharing the experience). Parents and young people were shocked when confronted with uncertainty about treatment and they felt responsible for the decision. They searched for further information, drew on their own experience, and struggled to weigh up risks of the treatments. Discussion with surgeons provided crucial support for decision-making, and young people were involved to a varying degree. In facilitating recovery, parents balanced increasing activity with protecting their child, but lacked knowledge about pain management, and how to improve strength and function of the arm. They hoped for a return to normal, including competitive sports. Conclusion. Surgeons are aware of the impact of injury on children and their parents; however, they may be less aware of the turmoil created by treatment uncertainty. Confident surgeons who appreciate and contextualize the importance of pre-existing experience and beliefs are best placed to help the family develop confidence to embrace uncertainty, particularly regarding participation in clinical trials.

Aims. Current American Academy of Orthopaedic Surgeons (AAOS) guidelines for treating femoral fractures in children aged two to six years recommend early spica casting although some individuals have recommended intramedullary stabilization in this age group. The purpose of this study was to compare the treatment and family burden of care of spica casting and flexible intramedullary nailing in this age group. Methods. Patients aged two to six years old with acute, non-pathological femur fractures were prospectively enrolled at one of three tertiary children’s hospitals. Either early closed reduction with spica cast application or flexible intramedullary nailing was accomplished under general anaesthesia. The treatment method was selected after discussion of the options by the surgeon with the family. Data were prospectively collected on patient demographics, fracture characteristics, complications, pain medication, and union. The Impact on Family Scale was obtained at the six-week follow-up visit. In all, 75 patients were included in the study: 39 in the spica group and 36 in the nailing group. The mean age of the spica group was 2.71 (2.0 to 6.9) years and the mean age of the nailing group was 3.16 (2.0 to 6.9) years. Results. All fractures healed without evidence of malunion or more than 2.0 cm of shortening. The mean Impact on Family score was 70.2 for the spica group and 63.2 (55 to 99) for the nailing group, a statistically significant difference (p = 0.024) in a univariate analysis suggesting less impairment of the family in the intramedullary nailing group. There was no significant difference between pain medication requirements in the first 24 hours postoperatively. Two patients in the spica group and one patient in the intramedullary nailing group required additional treatment under anaesthesia. Conclusion. Both early spica casting and intramedullary nailing were effective methods for treating femoral fractures in children two to six years of age. Intramedullary stabilization provides an option in this age group that may be advantageous in some social situations that depend on the child’s mobility. Fracture treatment should be individualized based on factors that extend beyond anatomical and biological factors. Cite this article: Bone Joint J 2020;102-B(8):1056–1061

Aims

The present study seeks to investigate the correlation of pubofemoral distances (PFD) to α angles, and hip displaceability status, defined as femoral head coverage (FHC) or FHC during manual provocation of the newborn hip < 50%.

Aims

The aim of this study was to explore clinicians’ experience of a paediatric randomized controlled trial (RCT) comparing surgical reduction with non-surgical casting for displaced distal radius fractures.

Purpose of the study. To determine the consistency with which specialist orthopaedic surgeons rate the importance of criteria for the diagnosis of DDH which had previously been generated in a BSCOS and EPOS multi national study. Methods. 163 members of BSCOS received a questionnaire containing 37 criteria that, in a previous study, had been found to be important for the diagnosis of DDH in infants under 8 weeks. A visual analogue scale was used to rate the importance of each criterion in the diagnosis of DDH. We determined the consistency using the intra-class correlation coefficient (values > .80 are anticipated). Analyses were preformed for all members of BSCOS and for geographic regions. Results. The response rate was 61%. Cronbach's α was .98 indicating that the pattern of the data observed was stable. The overall consistency was poor for all 37 criteria (ICC = .39 [95% CI .29, .52]). Surgeons were least consistent about criteria related to ultrasound (ICC = .25). The consistency for criteria related to patient characteristics (ICC = .40) and x-ray (ICC= .32) was better. Surgeons were most consistent (ICC = .51) about criteria related to clinical examination. Analyses based on regions of England, Scotland and Wales improved consistency by 25% (best ICC = .47) with West Midland, Yorkshire and Scotland rating top three. Conclusion. Surgeons' opinion about the importance of criteria for the diagnosis of DDH varies substantially across the UK. This study suggests a need to develop widely accepted criteria for the diagnosis of DDH that can be applied with sufficient degree of consistency among surgeons. Reducing inconsistency in this area should improve diagnosis and treatment

Aims

There is no consensus regarding optimum timing and frequency of ultrasound (US) for monitoring response to Pavlik harness (PH) treatment in developmental dysplasia of the hip (DDH). The purpose of our study was to determine if a limited-frequency hip US assessment had an adverse effect on treatment outcomes compared to traditional comprehensive US monitoring.

Aims

The aim of this study is to develop a core set of outcome domains that should be considered and reported in all future trials of childhood limb fractures.

At our institution surgical correction of symptomatic flat foot deformities in children has been guided by a paradigm in which radiographs and pedobarography are used in the assessment of outcome following treatment. Retrospective review of children with symptomatic flat feet who had undergone surgical correction was performed to assess the outcome and establish the relationship between the static alignment and the dynamic loading of the foot. A total of 17 children (21 feet) were assessed before and after correction of soft-tissue contractures and lateral column lengthening, using standardised radiological and pedobarographic techniques for which normative data were available. We found significantly improved static segmental alignment of the foot, significantly improved mediolateral dimension foot loading, and worsened fore-aft foot loading, following surgical treatment. Only four significant associations were found between radiological measures of static segmental alignment and dynamic loading of the foot. Weakness of the plantar flexors of the ankle was a common post-operative finding. Surgeons should be judicious in the magnitude of lengthening of the plantar flexors that is undertaken and use techniques that minimise subsequent weakening of this muscle group.

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

Aims

Open tibial fractures are limb-threatening injuries. While limb loss is rare in children, deep infection and nonunion rates of up to 15% and 8% are reported, respectively. We manage these injuries in a similar manner to those in adults, with a combined orthoplastic approach, often involving the use of vascularised free flaps. We report the orthopaedic and plastic surgical outcomes of a consecutive series of patients over a five-year period, which includes the largest cohort of free flaps for trauma in children to date.

Identification of the paediatric orthopaedic patient at high risk of venous thromboembolism (VTE) can allow a targeted approach to thromboprophylaxis. There is currently no national consensus on the correct method of risk assessment in this patient group. The Royal National Orthopaedic Hospital has developed a guideline using the evidence available to allow stratification of risk for the paediatric orthopaedic patient. A list of departments offering specialist paediatric orthopaedic surgery was obtained from the member list of the British Society of Paediatric Orthopaedic Surgeons (BSCOS). These hospitals were contacted via telephone interview to determine if they have a specific guideline or risk assessment proforma for paediatric VTE risk. A total of 74 hospitals were identified with a specialist paediatric orthopaedic practice in the United Kingdom. A response rate was gained from 100% of these hospitals. Only 3/74 of these hospitals had a guideline or protocol in place for the formal assessment of VTE risk in the paediatric patient (Royal National Orthopaedic Hospital, Stanmore; Sheffield Children's Hospital; Barts & the London NHS Trust). All three hospitals were able to provide details of their guideline. Both the RNOH and Barts & the London commented that their guideline was based on that of the Sheffield group, with adaptations for their own requirements. The majority of hospitals in the UK with a paediatric orthopaedic interest do not have guidance available for the management of VTE risk. Presented here is the outcome of using the limited evidence available, in combination with expert opinion, to develop a guideline suitable for the requirements of a paediatric unit in an orthopaedic hospital. This may be of benefit to other units producing their own guidelines, producing thought and discussion as to the specific requirements of paediatric patients undergoing orthopaedic procedures

Aim. Shelf acetabuloplasty is part of the armamentarium for the treatment of Legg-Perthes-Calve disease. Surgeons have used it to increase the anterolateral cover of the deformed head in advanced stages of the disease. However, others, including the senior author, advocate its use for containment of the diseased femoral head earlier in the disease, for both the prevention of further femoral head extrusion and as an aid in the remodelling process. The current study presents the results of this procedure performed from August 1999 to February 2010. Method. Full sets of x-rays were available for 44 patients (45 hips). Three other bilateral cases were treated with a unilateral shelf. Results. This series includes 34 boys and 10 girls with a mean age at diagnosis of 7.5 years (range 3.9 to 15.3). The average time to heal was 37.6 months (range 12–62.4). Over 80% of the hips were Elizabethtown stages 1 and 2 and almost 70% were Herring B at the time of surgery. However, 66% presented with more than two head-at-risk signs. Reimer's migration index and the deformity index were measured on initial, preoperative, postoperative and healed x-rays. The average deformity index at those four time points was significantly related to their final Stulberg classification. CE angles increased and Sharp angles decreased significantly as a result of treatment. Although many shelf grafts showed progressive resorption, the overall acetabular depth increased. At the healed stage, 82.2% of patients were Stulberg 3 or less, denying any pain and with full range of movement whilst 17.8% were classified as Stulberg 4. One of them required a Sugioka valgus osteotomy due to continuous pain. Conclusion. Shelf acetabuloplasty should be considered not only a salvage procedure but also indicated for the containment of extruded hips in earlier stages of Perthes disease

Aim. Our aim was to compare the Wilkins'-modified Gartland classification and AO classifications of supracondylar humeral fracture with respect to: -Inter-observer reliability; Association of fracture-grade with radiological quality of reduction; Association of fracture-grade with complications. Methods. The unit database was interrogated to identify all operated supracondylar fractures between 2007–2011. Radiographs from each case were evaluated by four observers (three consultants, one trainee) and classified according to Gartland and the AO system. Inter-observer reliability was calculated using Cohen's Kappa coefficient. Radiological quality of reduction was evaluated using a new scoring system, combining the anterior humeral line, the lateral capitello-humeral angle (LCHA) and Baumann's angle, (compared to reference values). Analysis of variance (ANOVA) was performed to determine whether there was a statistically significant difference in scores between the fracture grades. Case notes were reviewed for pre- and post-operative complication, and chi-squared test performed to compare the incidence between different fracture grades. Results. 83 cases were identified for fracture classification and 66 for assessment of reduction and complications. Inter-observer reliability was 0.58 for Gartland (moderate agreement), and 0.70 for the AO classification (good agreement). ANOVA demonstrated no significant difference in the overall reduction scores between the different grades of either classification. Mean scores for LCHA were lower for Gartland-2b (p=0.02) and AO-3 (p=0.007) groups (compared to Gartland-3 and AO-4). Complications were more frequent with the higher grades of fracture in both classifications (p<0.05). Conclusion. The AO classification has greater reliability and should be considered as an alternative to the Gartland classification. A higher grade of fracture is not associated with inferior radiographic outcomes. Surgeons should be aware that restoration of the LCHA is more difficult with the Gartland-2b and AO-3 fractures, probably because of the intact posterior cortex. A greater rate of complications should be expected with higher grades of fracture

Aims

The aim of this study was to compare the surgical and quality-of-life outcomes of children with skeletal dysplasia to those in children with idiopathic early-onset scoliosis (EOS) undergoing growth-friendly management.

Aims

We wished to examine the effectiveness of tibial lengthening using a two ring Ilizarov frame in skeletally immature patients. This is a potentially biomechanically unstable construct which risks the loss of axial control.

Supracondylar humeral fractures are common in children, but there are no classification systems or radiological parameters that predict the likelihood of having to perform an open reduction. In a retrospective case–control study we evaluated the use of the medial spike angle and fracture tip–skin distance to predict the mode of reduction (closed or open) and the operating time in fractures with posterolateral displacement. A total of 21 patients (4.35%) with a small medial spike angle (< 45°) were identified from a total of 494 patients, and 42 patients with a medial spike angle of > 45° were randomly selected as controls. The medial spike group had significantly smaller fracture tip–skin distances (p < 0.001), longer operating times (p = 0.004) and more complications (p = 0.033) than the control group. There was no significant difference in the mode of reduction and a composite outcome measure. After adjustments for age and gender, only fracture tip–skin distance remained significantly associated with the operating time (β = -0.724, p = 0.042) and composite outcome (OR 0.863 (95% confidence interval 0.746 to 0.998); p = 0.048).

Paediatric orthopaedic surgeons should have a lower threshold for open reduction when treating patients with a small medial spike angle and a small fracture tip–skin distance.

Proximal femoral resection (PFR) is a proven pain-relieving procedure for the management of patients with severe cerebral palsy and a painful displaced hip. Previous authors have recommended post-operative traction or immobilisation to prevent a recurrence of pain due to proximal migration of the femoral stump. We present a series of 79 PFRs in 63 patients, age 14.7 years (10 to 26; 35 male, 28 female), none of whom had post-operative traction or immobilisation.

A total of 71 hips (89.6%) were reported to be pain free or to have mild pain following surgery. Four children underwent further resection for persistent pain; of these, three had successful resolution of pain and one had no benefit. A total of 16 hips (20.2%) showed radiographic evidence of heterotopic ossification, all of which had formed within one year of surgery. Four patients had a wound infection, one of which needed debridement; all recovered fully. A total of 59 patients (94%) reported improvements in seating and hygiene.

The results are as good as or better than the historical results of using traction or immobilisation. We recommend that following PFR, children can be managed without traction or immobilisation, and can be discharged earlier and with fewer complications. However, care should be taken with severely dystonic patients, in whom more extensive femoral resection should be considered in combination with management of the increased tone.

We have reviewed our experience of the removal of deep extremity orthopaedic implants in children to establish the nature, rate and risk of complications associated with this procedure. A retrospective review was performed of 801 children who had 1223 implants inserted and subsequently removed over a period of 17 years. Bivariate analysis of possible predictors including clinical factors, complications associated with implant insertion and indications for removal and the complications encountered at removal was performed. A logistical regression model was then constructed using those predictors which were significantly associated with surgical complications from the bivariate analyses. Odds ratios estimated in the logistical regression models were converted to risk ratios.

The overall rate of complications after removal of the implant was 12.5% (100 complications in 801 patients), with 48 (6.0%) major and 52 (6.5%) minor. Children with a complication after insertion of the initial implant or with a non-elective indication for removal, a neuromuscular disease associated with a seizure disorder or a neuromuscular disease in those unable to walk, had a significantly greater chance of having a major complication after removal of the implant. Children with all four of these predictors were 14.6 times more likely to have a major complication.
