Acute musculoskeletal infection in children: assessment and management.

Musculoskeletal infection in children is challenging to treat, and includes septic arthritis, deep tissue infection, osteomyelitis, discitis and pyomyositis. Delays to diagnosis and management, and under-treatment can be life-threatening and result in chronic disability. The British Orthopaedic Association Standards for Trauma include critical steps in the timely diagnosis and management of acute musculoskeletal infection in children, the principles of acute clinical care and the service delivery requirements to appropriately manage this cohort of patients. Orthopaedic and paediatric services are likely to encounter cases of acute musculoskeletal infection in children and thus an awareness and thorough understanding of the British Orthopaedic Association Standards for Trauma guidelines is essential. This article reviews these guidelines and associated published evidence for the management of children with acute musculoskeletal infection.

Stabilization of Recurrent Elbow Instability in the Presence of Hyperlaxity in Children Using a Nonanatomic Soft Tissue Reconstruction.

Despite growing concordance of opinion in the adult setting, pediatric elbow instability and its management are poorly represented in the literature due to its low prevalence and often unique circumstances. The authors present a case of posttraumatic recurrent posterior pediatric elbow instability in a patient with joint hypermobility. Our patient, a 9-year-old girl, sustained a right-sided supracondylar fracture of the humerus in April 2019. Having been managed operatively, the elbow remained unstable and dislocated posteriorly in extension. Definitive surgical management was designed to provide a stable functional elbow. The principle of the surgery was to create a checkrein of tissue, not changing in length in extension and flexion, and to prevent further posterior elbow instability. A 3 mm slip of the central triceps tendon was dissected, leaving its attachment to the olecranon tip. Gracilis allograft was sutured to the strip of the triceps tendon to increase the tensile properties of the native tendon graft using a braided nonabsorbable suture. The tendon construct was then passed through a window made in the olecranon fossa and a transosseous tunnel in the ulna from the coronoid tip to the dorsal cortex. The tendon was tensioned and secured to the radial-dorsal aspect of the ulna with a nonabsorbable suture anchor in 90 degrees of flexion. At one year follow-up, the patient has a stable and pain-free elbow joint with no functional limitations.

The impact of instrumented gait analysis on decision-making in the interprofessional management of cerebral palsy: A scoping review.

BACKGROUND: Management of gait-related problems in children and young people with Cerebral Palsy (CYPwCP) is complex and requires an interprofessional approach. Irrespective of underlying mechanisms, instrumented gait analysis (IGA) can provide quantification of gait to support clinical decision-making for CYPwCP when planning treatment interventions. AIM: This scoping review aimed to determine the impact of instrumented gait analysis (IGA) on treatment decision-making for CYPwCP, paying particular attention to interprofessional decision-making. METHOD: PubMed, EMBASE, Web of Science and Scopus databases were searched from inception to October 2019 for studies including CYPwCP age<25 years. The PRISMA ScR protocol was followed, and Quality was assessed with the Downs and Black (D&B) scale. Influences on decision-making were coded according to the International Classification of Functioning, Disability and Health for Children and Youth framework (ICF-CY). RESULTS: Seventeen studies (1144 patients, 2.8-23 years) of varying quality (mean D&B = 17.2, range = 11-26) were included. Studies considered IGA influence at three decision-making stages 'Clinical Planning', 'Treatment Performed' and 'Follow up'. Child and Family, and Clinician and Service-centred factors had a high impact on engagement with IGA recommendations. INTERPRETATION: IGA guided recommendations can differ from initial clinical plans, and often lead to modification of the treatment ultimately performed. The effect on individual patients' outcomes when treatment recommendations based on instrumented gait analysis are followed is not yet clear and warrants further research. The differences in clinicians' engagement with IGA recommendations occur due to an array of Child and Family, and Clinician and Service-centred factors. Overall, IGA leads to less surgical recommendations, and has the potential to influence conservative gait-related management in CYPwCP.

Tibialis anterior tendon transfer using bone anchor for dynamic supination in congenital talipes equinovarus.

Tibialis anterior tendon transfer (TATT) is a recognised procedure for the treatment of recurrent congenital talipes equinovarus. The most common technique in use requires three skin incisions and breaching of the plantar tissues, risking pressure areas and damage to neurovascular structures. There have been no studies showing the clinical results of the use of a bone anchor to secure the tendon without drilling through the lateral cuneiform. This study presents the largest series of outcomes for such a procedure. Retrospective case series. Electronic records for all children under 18 undergoing TATT with anchor fixation included. Outcomes recorded were a failure of the tendon transfer and complications. Seventy-seven feet were identified in 61 children with a male-to-female ratio of 2.5:1, the average age at surgery of 5.6 years, and an average follow-up of 4.4 years. There were no cases of pullout of the anchor. Seventy-six cases (98.7%) had no recurrence of dynamic supination on follow-up. No revision surgery was required. Consistently reliable, reproducible and safe fixation of the tibialis anterior tendon in TATT can be achieved using a bone anchor for the treatment of dynamic supination in children with clubfeet following correction using the Ponseti method and is a quick and straightforward alternative method to traditional techniques.

The effect of COVID-19 on children with congenital talipes equinovarus in a tertiary service in the United Kingdom.

During the coronavirus disease 2019 (COVID-19) pandemic, many aspects of healthcare have been hindered. The primary aim of this study was to identify what the impact of COVID-19 was on the delivery of outpatient care for children with congenital talipes equinovarus deformity (CTEV) at a large tertiary hospital in the UK. This study reviewed the patients who commenced their Ponseti treatment between March and September 2020, representing the cohort who received hands-on care during the first wave of the COVID-19 pandemic. Equivalent 6-month periods were searched in 2019 and 2018 as control cohorts. This study included a total of 45 children (72 affected feet) presenting for treatment of clubfoot. Twenty-three babies were seen with CTEV in 2020. For the same time period in 2018 and 2019, 11 babies were treated each year. The distance commuted to by families was higher in 2020 compared to 2019 and 2018, although the difference did not reach statistical significance (P = 0.301). Treatment with Ponseti casting was commenced at a mean age of 52 days, with no statistically significant differences between cohorts (P = 0.758). Using strict precautions, the Ponseti service at a large tertiary hospital in the UK grew in size and successfully provided treatment for children presenting with CTEV during the first wave of the COVID-19 pandemic. This study has shown that with careful protocols in place, children with CTEV can be treated successfully during times of pandemic, thereby reducing the post-pandemic burden of older children requiring treatment.

Hemiepiphysiodesis: when should it be considered a day-case procedure?

Hemiepiphysiodesis is usually planned as a day-case but patients may stay overnight for pain control. In this study, we assessed the required level of analgesia (LOA) and length of stay (LOS) in patients undergoing hemiepiphysiodesis about the knee joint. We conducted a retrospective cohort study of patients that underwent temporary hemiepiphysiodesis of the distal femur or proximal tibia using hemiepiphysiodesis plates (eight-plates) for coronal plane deformities between January 2012 and October 2019. Demographics, type of procedure, anatomical site, anaesthetic time, preoperative, intraoperative and postoperative analgesia, and time of surgery were collected. Anterior hemiepiphysiodesis and permanent drill epiphysiodesis procedures were excluded. In this series of 79 patients, those with increased American Society of Anesthesiologists Score >1 and patients that were operated on >2 sites required increased LOA, (P < 0.05) and prolonged LOS (P < 0.05). The timing of surgery (morning vs. afternoon list) did not influence LOS or LOA. Patient-controlled analgesia (PCA) was required in 8 of 14 (57%) patients with four growth plates operated on. All (n = 12) patients that received PCA remained in hospital for at least one night. The use of local infiltration intraoperatively played a significant role in early discharge of the patients and t lower the LOA postoperatively (P < 0.05). Parameters including the number of growth plates operated on, use of tourniquet and intraoperative local infiltration can independently influence LOS and LOA postoperatively and at discharge. These parameters should be taken into consideration when consulting with the patient and family and when planning the postoperative course.

Effect of seasonal variation on the peak presentation of slipped capital femoral epiphysis. A comparison of children in Johannesburg, South Africa and London, UK.

Variation exists in the peak presentation of slipped capital femoral epiphysis (SCFE). The objective of this study was to compare two cohorts of children (South Africa and the UK) and explore similarities and differences regarding demographic and epidemiological features, incidence and seasonal variation in peak presentation. Patients presenting with SCFE at one of two hospitals were included in the study. A retrospective cohort was collected from hospital records. The following factors were recorded: duration of symptoms, chronicity, stability, seasonality, severity and prophylactic pinning. A total of 137 patients were included in the study - 70 patients (80 hips) from South Africa and 67 patients (73 hips) from the UK. Both sites recorded more than 50% incidence of a chronic slip. There was higher delay to presentation in the UK compared with South Africa (90 vs 60 days, P = 0.0262). The UK population were more skeletally mature (32.8% open triradiate cartilage) compared with the South Africa population (64.9% open triradiate cartilage). In both populations, the most common season of symptom onset was summer. In the UK, the most common season of symptom presentation was in autumn compared with summer in South Africa. This study found significant differences in the two countries, including a more skeletally mature population in the UK. Both cohorts showed seasonal variation in peak incidence, but there was more seasonal variation in peak incidence in the UK - in the summer for onset of symptoms and autumn months for time of presentation.

Assessment of the reliability and reproducibility of the Langenskiöld classification in Blount's disease.

The Langenskiöld classification is the most commonly utilized classification system for the radiological features of Blount's disease. Although there is only a single study found on the interobserver variability and none found on the intraobserver variability, it is commonly used for prognostication and guiding management decisions. The aim of this study was to determine the reliability and reproducibility of the Langenskiöld classification. A retrospective review of radiographs was done of patients treated for infantile and juvenile Blount's disease at Chris Hani Baragwanath Academic Hospital from 2006 to 2016. There were 70 radiographs of acceptable quality, which were reviewed and staged on two occasions according to the Langenskiöld classification by three orthopaedic consultants and three orthopaedic surgery senior residents. Pearson correlation coefficients, percentage agreements, and κ statistics were used to evaluate both the reliability and reproducibility. Of the 70 images staged, only two (2.9%) were staged the same by all six observers, and 20 (28.6%) images differed by a single stage. The consultants had 17 (24.3%) images staged the same whereas the residents had 12 (17.1%) images staged the same. The overall κ for all six observers showed a fair agreement of 0.24. Again, the consultants had a higher κ-value compared to residents of 0.25 and 0.24, respectively. The reproducibility amongst all observers was fair with a κ-value of 0.38. The consultants had a higher mean score of 0.48 compared to 0.26 for the residents. There was only a fair overall reliability and reproducibility amongst the six observers. We recommend the Langenskiöld classification be used with caution when being used for prognostication and management planning as well as when interpreting any research relying on this classification. Level of evidence: Level III, diagnostic study.

A systematic review of necrotising fasciitis in children from its first description in 1930 to 2018.

BACKGROUND: Necrotising fasciitis is a rapidly progressing soft-tissue infection with a low incidence that carries a relevant risk of morbidity and mortality. Although necrotising fasciitis is often fatal in adults, its case fatality rate seems to be lower in children. A highly variable clinical presentation makes the diagnosis challenging, which often results in misdiagnosis and time-delay to therapy. METHODS: We conducted a protocol-based systematic review to identify specific features of necrotising fasciitis in children aged one month to 17 years. We searched 'PubMed', 'Web of Science' and 'SCOPUS' for relevant literature. Primary outcomes were incidence and case fatality rates in population-based studies, and skin symptoms on presentation. We also assessed signs of systemic illness, causative organisms, predisposing factors, and reconstructive procedures as secondary outcomes. RESULTS: We included five studies reporting incidence and case fatality rates, two case-control studies, and 298 cases from 195 reports. Incidence rates varied between 0.022 and 0.843 per 100,000 children per year with a case-fatality rate ranging from 0% to 14.3%. The most frequent skin symptoms were erythema (58.7%; 175/298) and swelling (48%; 143/298), whereas all other symptoms occurred in less than 50% of cases. The majority of cases had fever (76.7%; 188/245), but other signs of systemic illness were present in less than half of the cohort. Group-A streptococci accounted for 44.8% (132/298) followed by Gram-negative rods in 29.8% (88/295), while polymicrobial infections occurred in 17.3% (51/295). Extremities were affected in 45.6% (136/298), of which 73.5% (100/136) occurred in the lower extremities. Skin grafts were necessary in 51.6% (84/162) of the pooled cases, while flaps were seldom used (10.5%; 17/162). The vast majority of included reports originate from developed countries. CONCLUSIONS: Clinical suspicion remains the key to diagnose necrotising fasciitis. A combination of swelling, pain, erythema, and a systemic inflammatory response syndrome might indicate necrotising fasciitis. Incidence and case-fatality rates in children are much smaller than in adults, although there seems to be a relevant risk of morbidity indicated by the high percentage of skin grafts. Systematic multi-institutional research efforts are necessary to improve early diagnosis on necrotising fasciits.

Prognostication in Developmental Dysplasia of the Hip Using the Ossific Nucleus Center Edge Angle.

BACKGROUND: The aim of this paper was to determine the prognostic potential of the ossific nucleus center edge angle (ONCEA) in patients below 5 years of age treated for developmental dysplasia of the hip (DDH) to predict final outcome and the need for a secondary procedure. METHODS: The interobserver and intraobserver reliability was calculated using the intraclass correlation coefficient for measurement of the ONCEA. The ONCEA was divided a priori into 3 groups: group A≥10 degrees, group B -9 to 9 degrees, and group C ≤-10 degrees. Final outcome was measured using the McKay score and Severin classification. The presence of osteonecrosis was recorded at final follow-up. RESULTS: One hundred one patients with 133 dislocated hips underwent closed or open reduction for DDH. Mean age at presentation was 19 months with a mean age at final follow-up of 12.4 years. A significant difference was shown in a comparison of the 3 ONCEA groups using the McKay score, Severin classification, and need for a secondary procedure. Eighty seven of the 101 patients underwent ONCEA reliability measurements. The ONCEA was shown to have a mean intrarater reliability of 0.89, and a mean interrater reliability of 0.77. CONCLUSIONS: The ONCEA is a reliable measurement in predicting medium-term outcome of the hip post reduction in children under the age of 5 years with DDH and might be useful as a predictor for a secondary procedure before the age of 5 years. LEVEL OF EVIDENCE: Level III-prognostic case control study. CLINICAL RELEVANCE: This case control study shows the importance of measuring the ONCEA within 6 months of removing the final cast after reduction of a dislocated hip and its implications for further management and outcome.

Failure of tension band plating: a case series.

Growth modulation with tension band plates (TBP) has been shown to be a very useful method for the treatment of angular deformities in growing children. Recently, we have observed cases of failure where the epiphyseal screw was drawn through the physis into the metaphysis. This study describes a series of children who developed this complication. Patients who developed TBP failure after operative treatment of lower limb angular deformities were identified from the databases at four institutions over a 5-year period. The medical records were reviewed to record demographics, primary diagnoses, details of the operative procedure, development of physeal arrest, and recurrence of the original deformity. Six patients (five girls) with nine implant failures were identified. The mean age of the children at the time of implant insertion was 7.2 years (range, 4-10 years). The primary diagnoses included hypophosphatemic rickets (n=7), congenital pseudoarthrosis of the tibia associated with neurofibromatosis 1 (n=1), and post-traumatic malunion after distal tibial fracture (n=1). Of the nine TBP that presented with the complication, four were inserted into the medial distal femur (one bilateral case), two into the medial proximal tibia (one bilateral case), two into the lateral distal tibia, and one into the medial distal tibia. None of these patients developed physeal growth arrest at the last follow-up as assessed on the latest radiographs. The use of TBP for guided growth in patients younger than 10 years old with rickets, neurofibromatosis, or other conditions that produce osteopenia leads to an increased risk for implant failure. In these cases, it is important to confirm that the epiphyseal screw has good purchase. Patients with these features should be monitored closely for early detection of this complication.

Mortality following snake bite envenomation by Bitis arietans in an HIV positive child: A case report.

Snake bites occur commonly in the rural areas of South Africa. Hospitals where snake bites are uncommon should always have protocols on standby in the event of such cases presenting. This is the first reported case documenting the effect of human immunodeficiency virus (HIV) on snake bite in South African children.A case report and review of relevant information about the case was undertaken.We present a case of a 1-year-old child referred from a peripheral hospital following a snake bite to the left upper limb with a compartment syndrome and features of cytotoxic envenomation. The patient presented late with a wide area of necrotic skin on the arm requiring extensive debridement. The underlying muscle was not necrotic. Polyvalent antivenom (South African Institute of Medical Research Polyvalent Snakebite Antiserum) administration was delayed by 4 days after the snake bite. The patient was also diagnosed with HIV and a persistent thrombocytopenia possibly due to both HIV infection and the snake bite venom. Lower respiratory tract infections with subsequent overwhelming sepsis ultimately resulted in the child's death.The case highlights the challenge of treating a snake bite in a young child with HIV and the detrimental outcome of delayed treatment. A protocol is essential in the management of snake bites in all hospitals.Level IV, Case report.This case highlights the interaction of snake bite envenomation and HIV infection on thrombocytopenia.

Vitamin D Status in Blount Disease.

INTRODUCTION: Blount disease can be defined as idiopathic proximal tibial vara. Several etiologies including the mechanical theory have been described. Obesity is the only causative factor proven to be associated with Blount disease. The aim of this study is to assess if there is an association of vitamin D deficiency and Blount disease. METHODS: This a retrospective study of preoperative and postoperative patients with Blount disease who were screened for vitamin D deficiency. Patients with genu varum due to confirmed vitamin D deficiency and rickets were excluded. The study patients had the following blood tests done: calcium, phosphate, alkaline phosphatase, parathyroid, and 25-hydroxyvitamin D (25(OH)D) hormones. RESULTS: We recruited 50 patients. The mean age of these patients was 10.4 years (SD±3.88) with average body mass index of 28.7 kg/m (±10.2). Thirty (60%) patients were diagnosed with infantile, 4 (8%) juvenile, and 16 (32%) adolescent Blount disease. Eight (16%) patients were found to be vitamin D deplete (25(OH)D levels <50 nmol/L). Of these, 8 patients, 6 were insufficient (25(OH)D levels between 30 and 50 nmol/L) and the other 2 were deficient (25(OH)D levels <30 nmol/L). CONCLUSIONS: This study showed that the prevalence of vitamin D deficiency in children with Blount disease was similar to that of healthy children living in Johannesburg. There is no evidence that vitamin D deficiency is a factor in causing Blount disease. LEVEL OF EVIDENCE: Level III-retrospective study.

Common normal variants of pediatric vertebral development that mimic fractures: a pictorial review from a national longitudinal bone health study.

Children with glucocorticoid-treated illnesses are at risk for osteoporotic vertebral fractures, and growing awareness of this has led to increased monitoring for these fractures. However scant literature describes developmental changes in vertebral morphology that can mimic fractures. The goal of this paper is to aid in distinguishing between normal variants and fractures. We illustrate differences using lateral spine radiographs obtained annually from children recruited to the Canada-wide STeroid-Associated Osteoporosis in the Pediatric Population (STOPP) observational study, in which 400 children with glucocorticoid-treated leukemia, rheumatic disorders, and nephrotic syndrome were enrolled near glucocorticoid initiation and followed prospectively for 6 years. Normal variants mimicking fractures exist in all regions of the spine and fall into two groups. The first group comprises variants mimicking pathological vertebral height loss, including not-yet-ossified vertebral apophyses superiorly and inferiorly, which can lead to a vertebral shape easily over-interpreted as anterior wedge fracture, physiological beaking, or spondylolisthesis associated with shortened posterior vertebral height. The second group includes variants mimicking other radiologic signs of fractures: anterior vertebral artery groove resembling an anterior buckle fracture, Cupid's bow balloon disk morphology, Schmorl nodes mimicking concave endplate fractures, and parallax artifact resembling endplate interruption or biconcavity. If an unexpected vertebral body contour is detected, careful attention to its location, detailed morphology, and (if available) serial changes over time may clarify whether it is a fracture requiring change in management or simply a normal variant. Awareness of the variants described in this paper can improve accuracy in the diagnosis of pediatric vertebral fractures.

Lengthening of the gastrocnemius-soleus complex: an anatomical and biomechanical study in human cadavers.

BACKGROUND: Lengthening of the gastrocnemius-soleus complex is frequently performed for equinus deformity. Many techniques have been described, but there is uncertainty regarding the precise details of some surgical procedures. METHODS: The surgical anatomy of the gastrocnemius-soleus complex was investigated, and standardized approaches were developed for the procedures described by Baumann, Strayer, Vulpius, Baker, Hoke, and White. The biomechanical characteristics of these six procedures were then compared in three randomized trials involving formaldehyde-preserved human cadaveric lower limbs. After one of the lengthening procedures was performed, a measured dorsiflexion force was applied across the metatarsal heads with use of a torque dynamometer. Lengthening of the gastrocnemius-soleus complex was measured directly, by measuring the gap between the ends of the fascia or tendon. RESULTS: The gastrocnemius-soleus musculotendinous unit was subdivided into three zones. In Zone 1, it was possible to lengthen the gastrocnemius-soleus complex in either a selective or a differential manner-i.e., to lengthen the gastrocnemius alone or to lengthen the gastrocnemius and soleus by different amounts. The procedures performed in this zone (Baumann and Strayer procedures) were very stable but were limited with regard to the amount of lengthening achieved. Zone-2 lengthenings of the conjoined gastrocnemius aponeurosis and soleus fascia (Vulpius and Baker procedures) were not selective but were stable and resulted in significantly greater lengthening than Zone-1 procedures (p < 0.001). In Zone 3 (Hoke and White procedures), lengthenings of the Achilles tendon were neither selective nor stable but resulted in significantly greater lengthening than Zone-1 or 2 procedures (p < 0.001). CONCLUSIONS: Surgical procedures for the correction of equinus deformity by lengthening of the gastrocnemius-soleus complex vary in terms of selectivity, stability, and range of correction. Procedures for the correction of equinus deformity have different anatomical and biomechanical characteristics. Clinical trials are needed to determine whether these differences are of clinical importance. It may be appropriate for surgeons to select a procedure involving the zone best suited to the clinical needs of a specific patient.

Multilevel surgery for equinus gait in children with spastic diplegic cerebral palsy: medium-term follow-up with gait analysis.

BACKGROUND: In children with spastic diplegia, surgery for ankle equinus contracture is associated with a high prevalence of both overcorrection, which may result in a calcaneal deformity and crouch gait, and recurrent equinus contracture, which may require revision surgery. We sought to determine if conservative surgery for equinus gait, in the context of multilevel surgery, could result in the avoidance of overcorrection and crouch gait as well as an acceptable rate of recurrent equinus contracture at the time of medium-term follow-up. METHODS: This was a retrospective, consecutive cohort study of children with spastic diplegia who had had surgery for equinus gait between 1996 and 2006. All children had distal gastrocnemius recession or differential gastrocnemius-soleus complex lengthening, on one or both sides, as part of single-event multilevel surgery. The primary outcome measures were the Gait Variable Scores (GVS) and Gait Profile Score (GPS) at two time points after surgery. RESULTS: Forty children with spastic diplegia, Gross Motor Function Classification System (GMFCS) level II or III, were included in this study. There were twenty-five boys and fifteen girls. The mean age was ten years at the time of surgery and seventeen years at the time of final follow-up. The mean postoperative follow-up period was 7.5 years. The mean ankle GVS improved from 18.5° before surgery to 8.7° at the time of short-term follow-up (p < 0.005) and 7.8° at the time of medium-term follow-up. The equinus gait was successfully corrected in the majority of children, with a low rate of overcorrection (2.5%) and a high rate of recurrent equinus (35%), as determined by sagittal ankle kinematics. Mild recurrent equinus was usually well tolerated and conferred some advantages, including contributing to strong coupling at the knee and independence from using an ankle-foot orthosis. CONCLUSIONS: Surgical treatment for equinus gait in children with spastic diplegia was successful, at a mean of seven years, in the majority of cases when combined with multilevel surgery, orthoses, and rehabilitation. No patient developed crouch gait, and the rate of revision surgery for recurrent equinus was 12.5%.

Pediatric noncontiguous spinal injuries: the 15-year experience at a level 1 trauma center.

STUDY DESIGN: Retrospective review. OBJECTIVE: To determine the incidence and clinical characteristics of noncontiguous spinal injuries (NCSI) in a pediatric population. The secondary objective is to identify high-risk patients requiring further imaging to rule out NCSI. SUMMARY OF BACKGROUND DATA: NCSI can add significant complexity to the diagnosis, management, and outcome of children. There is very little in the pediatric literature examining the nature, associated risk factors, management, and outcomes of NCSI. METHODS: All children up to 18 years of age with a spinal injury, as defined by International Classification of Diseases, Ninth Revision codes, at one pediatric trauma hospital were included (n = 211). Data for patient demographics, mechanism of injury, spinal levels involved, extent of neurological injury and recovery, associated injuries, medical complications, treatment, and outcome were recorded. RESULTS: Twenty-five (11.8%) of 211 patients had NCSI, with a median age of 13.0 years (interquartile range = 8-15). The most common pattern of injury was a double thoracic noncontiguous injury. Sixteen percent of the cases of NCSI were initially missed, with no clinical deterioration due to missed diagnosis. Associated injuries occurred in 44% of patients with NCSI. Twenty-four percent of patients with multiple NCSI had a neurological injury compared with 9.7% in patients with single-level or contiguous injuries (P = 0.046). CONCLUSION: There is a high incidence of children with multiple NCSI who are more likely to experience neurological injuries compared with patients with single-level or contiguous spinal injuries. Patients with a single-level spinal injury on existing imaging with an associated neurological injury should undergo at least plain films of the entire spine to exclude noncontiguous injuries. In patients without neurological injury and a single spinal fracture, radiography showing at least 4 levels above and below the fracture should be performed. All children with spinal injury should have associated injuries carefully excluded.

Epidemiology of acute osteoarticular sepsis in a setting with a high prevalence of pediatric HIV infection.

BACKGROUND: There is limited information on osteoarticular infections in human immunodeficiency virus (HIV)-infected children. The purpose of this study was to determine the effect of HIV on the epidemiology of osteoarticular infections in a setting with a high prevalence of pediatric HIV infection. METHODS: A retrospective evaluation of children presenting with acute septic arthritis or osteomyelitis from June 2005 to July 2009 was undertaken. Standard departmental protocols for the management of osteoarticular infections, including testing for HIV, were practised. RESULTS: A total of 102 cases of acute septic arthritis or osteomyelitis were identified during the study period. These included 22 (21.6%) episodes in HIV-infected children, 66 (64.7%) in HIV-non-infected children, and 14 (13.7%) cases in whom the HIV status was unknown. The median age of children was 30.6 months (range, 9.2 to 82.9 mo) and did not differ by HIV status. Streptococcus pneumoniae was identified in 8 of 12 (66.7%) HIV-infected children compared with 3 (9.7%) of 31 HIV-non-infected children (P<0.001). Conversely, fewer episodes in HIV-infected children (4.8%) were associated with Staphylococcus aureus compared with HIV-non-infected children (24.6%; P=0.06). No patients died. Twelve cases required repeated surgical procedures. CONCLUSIONS: Empirical management of osteoarticular infections in settings with a high prevalence of HIV-infected children or children known to be HIV infected needs to be tailored based on a higher proportion of episodes being due to S. pneumoniae in HIV-infected children. CLINICAL RELEVANCE: Our results suggest that HIV-infected children with osteoarticular infections should be started on broader spectrum antibiotics before culture results are available. LEVEL OF EVIDENCE: Level IV, diagnostic study.
