Chronic infection and infected non-union of the long bones in paediatric patients: preliminary results of bone versus beta-tricalcium phosphate grafting after induced membrane formation.

PURPOSE: Chronic infection (CO) and infected non-union of the long bones are relatively rare conditions in paediatric patients. Large bone defects secondary to these conditions can be managed with the induced membrane technique. The technique requires grafting of the bone void, although it is not yet established what bone substitute is the best option. The aim of this work was to evaluate the outcome and efficacy of treatment in children with CO and infected non-union of the long bones using the induced membrane technique and bone (BG) versus beta-tricalcium phosphate (BTP) grafting. METHODS: Eight skeletally immature patients with CO and infected non-union of the long bones were treated surgically between 2010 and 2017 by a combination of resection of necrotic infected bone, debridement of surrounding soft tissue, osteosynthesis using a stable internal fixation when needed, and application of antibiotic-laden cement (ALC) spacer inducing new membrane before final bone reconstruction with bone substitutes: BTP in five cases, BG (allograft and/or autologous graft) in three cases. A second surgical step, once inflammatory markers had normalized, consisted of ALC spacer removal, application of BG or BTP graft and concomitant stable osteosynthesis, if needed, if this had not been done during the first surgical stage. All the patients underwent clinical, laboratory and imaging evaluation before and after surgery. Antibiotics were adjusted according to culture and sensitivity. RESULTS: Mean patient age at time of diagnosis was 13 ± four years (range, 4-16) and all had at least a 12-month follow-up (range 12-60). Estimated time for induced membrane formation was significantly shorter in patients treated with BTP compared with BG: 3±1 vs. 10±2 (p = 0.02). This result was confirmed by multivariate analysis (p = 0.044) taking into account adjustment for age of patients and time after initial surgery. Time of final union was about 5.5 ± 4.1 months (range 2-66). At the last follow-up visit, bone had healed and all the patients had resumed daily living and sports activities. CONCLUSION: The induced membrane technique with BG or BTP graft can achieve bone healing in large bone defects secondary to CO and infected non-union in children and adolescents. The choice of bone substitute is important. Our preliminary results show graft integration and bone healing can be expected sooner if BTP is used as bone void filler.

Deep postoperative spine infection treated by negative pressure therapy in patients with progressive spinal deformities.

BACKGROUND: The aim of the study is to review the outcome of using the VAC system in children and adolescents who have developed postoperative spinal infection after posterior instrumented spinal fusion, and to evaluate whether this technique is also feasible in patients treated with posterior instrumented fusion with polyester sublaminar bands. METHODS: A total of 11 out of 118 consecutive children and adolescents (5 males) with deep postoperative spinal infection were identified; infections were categorised as early (acute), delayed (subacute) or late (chronic) according to time of onset. Irrespective of the etiology and the onset, all the deep infections were managed with the reported technique. All the patients had regular clinical and radiological follow-up. RESULTS: Eight out of 11 patients developed an early (72.7%), 2 a delayed (18.2%) and 1 a late deep postoperative infection (9.1%); 7 out of 11 (63.6%) showed severe mental compromise. No statistically significant differences were observed for mean number of VAC dressing changes (p = 0.81) and mean length of hospitalisation comparing patients with early infection versus patients with delayed or late infections (p = 0.32). Mean number of VAC dressing changes (p = 0.02) and mean number of hospitalisation days (p = 0.05) were higher in patients with underlying neurological disorders than in those without, while mean length of hospitalisation was longer in neuromuscular patients. CONCLUSIONS: The application of the VAC system, as an adjunct to surgical debridement and adequate antibiotic therapy, is a reliable method for the treatment of postoperative infection in children and adolescents undergoing spinal instrumentation and fusion. It can reduce the need for further complex soft-tissue procedure, removal of hardware with consequent loss of correction, and pseudoarthrosis. Finally, the use of VAC therapy is not contraindicated in patients treated with hybrid constructs with sublaminar bands. LEVEL OF EVIDENCE: III.

Rod Migration Into the Spinal Canal After Posterior Instrumented Fusion Causing Late-Onset Neurological Symptoms.

BACKGROUND: Rod migration into the spinal canal after posterior instrumented fusion is a rare complication causing late-onset neurological symptoms. The purpose of the present study is to report a case of a 13-year-old boy with spastic cerebral palsy and related neuromuscular kyphoscoliosis who developed late-onset neurological deterioration secondary to progressive implant migration into the spinal canal over a 5-year period. METHODS: A decision was made to remove both rods to achieve decompression. Intraoperative findings were consistent with information gained from preoperative imaging. The rods were found to have an intracanal trajectory at T9-T10 for the right rod and T12-L2 for the left rod. RESULTS: The cause of implant migration, with progressive laminar erosion slow enough to generate a solid mass behind, was progressive kyphosis in a skeletally immature patient with neuromuscular compromise. CONCLUSIONS: Fixation type, early surgery, and spasticity management contributed significantly to the presenting condition. Mechanical factors and timing of surgery played a decisive role in this particular presentation. LEVEL OF EVIDENCE: Level IV--Case report and review of the literature.

Radiological, clinical and functional evaluation using the Quick Disabilities of the Arm, Shoulder and Hand questionnaire of children with medial epicondyle fractures treated surgically.

PURPOSE: The main goal of this study was to retrospectively evaluate the clinical, functional and radiographic outcomes of displaced medial epicondyle fractures with or without associated elbow dislocation in children undergoing surgical treatment and to evaluate upper-extremity function with the Quick Disbilities of the Arm, Shoulder and Hand (Quick DASH) questionnaire. The hypothesis was that patients with associated elbow dislocation would have similar functional outcome to patients with displaced fractures with or without intra-articular entrapment of the medial epicondyle. METHODS: A review of medical charts was performed to identify all children and adolescents who underwent surgical treatment for displaced medial epicondyle humeral fractures managed at a single institution. Patients with a closed fracture on plain radiographs, presence of growth cartilages and managed surgically were included in the study. Fractures were radiologically assessed on anteroposterior and lateral radiographs and rated according to Papavasiliou and Crawford classification. Functional outcome was measured with the Quick DASH questionnaire. Sixty-six patients met inclusion criteria, and 38 children presented with isolated displaced medial epicondyle fracture (Group A: type II and type III) and 28 with medial epicondyle fractures associated with elbow dislocation (Group B: type IV). RESULTS: The Papavasiliou and Crawford system classified 36 fractures as type II (54.6%), two (3%) as type III and 28 as type IV (42.4%). All patients underwent open reduction. Fracture fixation was performed with K-wires in 26 (35%) children and a with single screw in 40 (65%). Mean follow-up was 37.5 months (range, 12-68). Overall complication rate was 18%. In particular, three adverse events (3/38, 8%) were recorded in Group -A and nine (9/28, 32%) in Group B (p = 0.003). Mean Quick DASH score at final follow-up was 4.6 ± 3.8 (range, 0-15.9) and was not significantly different between Groups A (5.4 ± 4.3; range, 0-15.9) and B (4.1 ± 3.5; range, 0-15.9) (p > 0.05). CONCLUSIONS: Children with type II, III and IV medial epicondyle fractures undergoing surgical treatment have good radiological, clinical and functional outcome but warrant special attention to detect intra-articular entrapment of the broken epicondyle. In these cases, both patient and family should be warned of the potential risk of loss of elbow range of motion and possibly poor functional outcome, especially if treatment is delayed.

Clinical and radiological outcome of calcaneal lengthening osteotomy for flatfoot deformity in skeletally immature patients.

BACKGROUND: The purpose of this study was to evaluate the clinical, functional and radiological outcome of calcaneal lengthening osteotomy for the treatment of symptomatic flatfoot deformity in skeletally immature patients. METHODS: A retrospective review was led on 31 prospectively enrolled patients with symptomatic flatfoot. Twenty-seven out of 31 patients met the inclusion criteria, for a total of 38 operated feet. Mean age at time of surgery was 13.3 ± 2.2 years (range 7.8-17). Mean BMI at time of surgery was 19.3 ± 4.9 (range 12.3-32). In order to assess clinical and functional outcome, all patients were evaluated according to Yoo et al., Mosca and AOFAS clinical criteria before surgery and at last follow-up visit. Moreover, all patients underwent anteroposterior and lateral weight-bearing foot radiographs preoperatively, at 3-4-month post-surgery and at last follow-up visit. RESULTS: Average Yoo et al. score was 3.3 ± 1 (range 0-4) preoperatively and improved to 9.8 ± 2.1 (range 3-12) at last follow-up (p < 0.001). Clinical outcome was satisfactory in 34 feet (89%) and unsatisfactory in 4 feet (11%). The same results were observed when Mosca clinical criteria were applied. AOFAS score improved significantly from a preoperative mean value of 49.9 ± 16 (range 23-75) to a postoperative value of 89 ± 15.9 (range 34-100) (p < 0.001). All radiographic parameters improved significantly from mean preoperative to mean 3-4-month postoperative value. Correction was maintained at last follow-up visit. Postoperative radiographs showed calcaneocuboid (C-C) joint subluxation in 29 (76%) feet. Final AP and lateral foot radiographs showed complete bone union and good bone graft remodeling. Furthermore, correct joint alignment was restored in all but two patients (93%). CONCLUSIONS: Calcaneal lengthening osteotomy is not contraindicated in symptomatic flatfoot of different etiologies, except neuromuscular disease-related flatfoot that can affect bone quality and reduce foot flexibility. C-C joint subluxation is frequently observed but has little functional impact as it tends to remodel over time.

Successful treatment of chronic osteomyelitis in children with debridement, antibiotic-laden cement spacer and bone graft substitute.

PURPOSE: Chronic osteomyelitis and infected nonunion are relatively rare conditions in pediatric patients and are more frequently seen in developing countries. Although relatively rare, they are medically and surgically challenging. Here we report a novel surgical technique used to manage five patients with chronic osteomyelitis of long bones. METHODS: Five skeletally immature patients with chronic osteomyelitis and infected nonunion of the long bones were treated surgically between 2010 and 2014 by a combination of resection of necrotic infected bone, debridement of surrounding soft tissue, and application of antibiotic-laden cement spacer inducing periosteal membrane before final bone reconstruction. Once inflammatory markers normalized, all the patients were re-operated for cement removal, bone graft substitution, and concomitant osteosynthesis of the affected bone, if needed. All patients underwent MRI, CT scan, and laboratory evaluation prior to surgery. The antibiotic regimen was started empirically and then adjusted according to culture and sensitivity results. RESULTS: Mean patient age at the time of diagnosis was 11 years (range 4-14), and all patients had at least 2-year follow-up (range 2-5). At last follow-up, clinical and laboratory evaluation had normalized, the bone had healed, and all patients had resumed daily living and sports activities. CONCLUSION: Surgical debridement is the standard approach to chronic osteomyelitis. Use of antibiotic-laden cement is recommended to penetrate local infection, with antibiotic therapy playing an adjunctive role. The cement also induces membrane formation that aids bone reconstruction. LEVEL OF EVIDENCE: IV.

Displaced Tibial Shaft Fractures With Intact Fibula in Children: Nonoperative Management Versus Operative Treatment With Elastic Stable Intramedullary Nailing.

BACKGROUND: The main objective of this study was to retrospectively evaluate the clinical and radiographic outcomes of displaced tibial shaft fractures with intact fibula in children after nonoperative management and operative treatment by elastic stable intramedullary nailing. METHODS: A study was performed on 80 consecutive children, 56 males, 24 females from 2 Institutions, with displaced and closed tibial shaft fracture with intact fibula. All patients underwent regular clinical and radiographic follow-up visits for at least 2 years after injury. RESULTS: In total, 26 patients (group A-Institution I) were treated surgically by elastic stable intramedullary nailing and 54 patients (18 patients from group B-Institution I and 36 patients from group C-Institution II) were treated nonoperatively with closed reduction and casting. groups A, B, and C did not significantly differ on sex (P=0.37), side (P=0.54), and fracture site (P=0.14).Valgus deformity was significantly controlled in group A patients only (P=0.001); during follow-up in group B patients (P=0.017), and showed no significant change between pretreatment images and last follow-up in group C patients (P=0.71). Procurvatum deformity was significantly controlled in group A patients only (P=0.001); it showed no significant improvement after conservative treatment in group B (P=0.73) and C patients (P=0.8). Recurvatum was significantly improved in group A (P<0.001) and C patients (P<0.001) but remained unchanged in group B patients (P=0.15). Varus deformity improved significantly in all patient groups.Immobilization time was significantly shorter in group A compared with group B and C patients (P<0.001).However, numerical differences, although statistically significant, were not clinically relevant for all variables but immobilization time. CONCLUSIONS: This study showed good functional and radiologic outcomes in the pediatric population who had sustained closed, traumatic, displaced fracture of tibial diaphysis without associated fibula fracture.On the basis of the findings reported here, it is not contraindicated to operate skeletally immature patients with displaced fracture of tibial diaphysis without associated fibula fracture. However, results were essentially the same and either method is a satisfactory choice for pediatric tibia shaft fractures with an intact fibula. In particular, we found that conservative treatment was as efficacious as surgical treatment apart from the length of time for immobilization. LEVEL OF EVIDENCE: Level III.

Complications of elastic stable intramedullary nailing of femoral shaft fractures in children weighing fifty kilograms (one hundred and ten pounds) and more.

AIM: The purpose of this study was to assess treatment outcomes in children weighing 50 kg (110 pounds) or more with displaced femur shaft fractures treated by elastic stable intramedullary nailing (ESIN) and to identify potential correlations between nail size/medullary canal diameter ratio and outcome. METHODS: Twenty out of 117 consecutive children surgically treated by ESIN for displaced fractures of the femoral shaft with no associated neurovascular injury weighed 50 kg (110 pounds) or more. All patients underwent regular clinical and radiographic follow-up for at least one year after their index surgery. RESULTS: The average patient age at the time of injury was 13.1 years (25th and 75th interquartile range [IQR] = 11.7-14.5). The mean follow-up was 27.4 months (IQR = 18.4-36.8). Overall, nine (45 %) adverse events were observed. The rate of complications was higher among children weighting 55 kg and over (67 %) than in children weighing less than 55 kg (35 %) and among children aged 13 years old or older (72 %) than among children younger than 13 years old (11 %). DISCUSSION: Femoral shaft fractures in children and adolescents weighing 50 kg (110 pounds) and over and older than ten years of age have an increased rate of complications. CONCLUSION: Heavier patients have a greater chance of complications. In particular, patients younger than 13 years old and weighing less than 55 kg can be safely managed with ESIN, but older and heavier patients should preferably be treated with rigid fixation systems due to a greater complication rate. However, further studies are needed to consolidate the conclusions.

Serial elongation derotation flexion (EDF) casting for patients with infantile and juvenile scoliosis.

Infantile and juvenile scoliosis, among different types of spinal deformity, is still a challenge for pediatric orthopedic surgeons. The ideal treatment of infantile and juvenile scoliosis has not yet been identified as both clinicians and surgeons still face multiple challenges, including preservation of the thoracic spine, thoracic cage, lung growth and cardiac function without reducing spinal motion. Elongation, derotation, flexion (EDF) casting technique is a custom-made thoracolumbar cast based on a three dimensional correction concept. This cast offers three-dimensional correction and can control the evolution of the deformity in some cases. Spinal growth can be guided by EDF casting as it can influence the initially curved spine to grow straighter. This article aimed to provide a comprehensive review of how infantile and juvenile scoliosis can affect normal spine and thorax and how these deformities can be treated with serial EDF casting technique. A current literature review is mandatory in order to understand the principles of the serial EDF casting technique and the effectiveness of conservative treatment in young and very young patients.

Risk factors for re-fracture in children with diaphyseal fracture of the forearm treated with elastic stable intramedullary nailing.

A retrospective study aims to investigate predisposing factors leading to re-fracture in patients with nails still in place and to identify potential correlations between nail size-to-medullary canal diameter ratio and re-fracture, working to the hypothesis that a higher ratio correlates with a higher risk of re-fracture. Rates of re-fracture with nail still in place after forearm elastic stable intramedullary nailing are higher in younger pediatric patients. Re-fractures occurred at a mean age of 6.7 years (range 5-8.7). While the role of body frame and bone medullary diameter remains unclear, there are grounds for adjusting treatment strategy for age, weight and bone medullary diameter to achieve effective outcome. History of previous forearm fracture and open treatment may also be further risk factors.

Outcome of Displaced Fractures of the Distal Metaphyseal-Diaphyseal Junction of the Humerus in Children Treated With Elastic Stable Intramedullary Nails.

BACKGROUND: The main objective of this study was to retrospectively evaluate the clinical and radiographic outcomes of displaced distal humeral metaphyseal-diaphyseal junction fractures in children treated by elastic stable intramedullary nailing (ESIN). METHODS: During the study period, 14 consecutive children with fractures of the distal humeral metaphyseal-diaphyseal junction were surgically treated by ESIN. All patients underwent full-length preoperative and postoperative anteroposterior and lateral radiographs of the injured humerus. One year after the index surgery, patients were asked to answer the short version of the Disabilities of the Arm, Shoulder and Hand outcome questionnaire (Quick DASH). RESULTS: During the study period, fractures of the distal metaphyseal-diaphyseal humeral junction represented 1.5% (16/1100) of all humeral fractures. Fourteen patients underwent surgery and met the inclusion criteria. The male to female ratio was 1:1. The average patient age at the time of injury was 9.7 years (range, 3.6 to 13.7 y). The left and right sides were equally affected. The mean follow-up was 28.1 months (range, 20 to 38 mo).Radiologically, no secondary displacement, nail migration, loss of fixation, consolidation delay, nonunion, or refracture was noted. None of the patients showed signs of growth arrest on either radiologic or clinical assessment.All patients returned to their previous daily and sport activities without discomfort or difficulty, and they were free of pain at their last follow-up visits. The injured elbow range of motion was comparable with that of the contralateral side at the last follow-up visit in all patients. The mean Quick DASH score was 0.81 (range, 0 to 6.8). CONCLUSIONS: We recommend surgery for displaced fractures of the distal humeral metaphyseal-diaphyseal junction. ESIN results in stable reduction, good rotational control, and faster mobilization. LEVEL OF EVIDENCE: Level IV.

Radiologic, clinical, and functional evaluation of children with lateral humeral condyle fractures using the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire.

This study investigated the clinical and radiologic outcomes of lateral humeral condyle (LHC) fractures in children and evaluated the functional outcome of these injuries according to the type of treatment using the Quick DASH questionnaire. Data on consecutive children admitted to the Emergency Department for LHC fracture (01/11-12/18) were collected from their charts. Anterior-posterior and lateral radiographs of the injured elbow were used to classify each fracture according to Jakob's classification, and to detect any other concomitant bone lesions. Data on pain, stiffness, impact on daily activities, skin lesions, surgical-site infection, and range of motion were retrieved. The Quick DASH questionnaire was used to evaluate functional outcome. Forty-eight children with a mean age at trauma of 6.06 ± 2.22 years (32 males; mean follow-up: 75 ± 25 months) were reviewed. The overall Quick DASH score was 4 (0-15.9); it was 2.69 ± 0.31 in Jakob-1 ( n = 12; 25%), 3 ± 1.06 in Jakob-2 ( n = 19; 39.6%), and 3.06 ± 1.56 in Jakob-3 fractures ( n = 17; 35.4%). Functional outcomes were similar irrespective of the severity of displacement, type of treatment, length of postoperative immobilization, and presence of associated fracture ( P > 0.05). Quick DASH scores in children less than 8 years (2.77 ± 0.44) and in those more than 8 years (3.47 ± 2.13) were similar ( P > 0.05). Five out of 48 patients developed one complication (10.5%). Good functional and radiologic outcomes can be expected in children with LHC fractures irrespective of the amount of initial displacement, type of treatment, length of postoperative immobilization, and age at surgery. Families should be warned about potential complications although these are most often minor. Level of evidence: III.

Review of pediatric functional outcomes measures used to evaluate surgical management in pediatric patients with an upper extremity fracture.

For two decades, many scores, questionnaires, and rating systems have been used to evaluate the functional outcome of children with an upper extremity fracture (UEF). However, only a few of these were created specifically for children, and many assess only elbow function. In the absence of any published review on this topic, we set out to identify and categorize different scores used to evaluate the clinical and functional outcomes of surgically treated pediatric UEFs. A literature search was performed, and 38 studies were identified. The scores used more often were the shortened version of the Disability of the Arm, Shoulder and Hand questionnaire and the Mayo Elbow Performance Score/Index. In a lower number of studies, authors used other scoring systems, including the Mayo Wrist Score, the Patient-Rated Wrist Evaluation, the Patient-Rated Elbow Evaluation, the Métaizeau functional scoring system, the Oxford Elbow Score, the Price and Flynn criteria, the Hardacre Functional Score, the Neer Shoulder Score, the Constant-Murley Shoulder Score, the Modified Orthopedic Trauma Association Score, the Medical Outcomes Study Short Form-36, and the Pediatric Outcomes Data Collection Instrument. Some specific pediatric scoring systems to evaluate the functional outcome of children with a UEF have been suggested, but a single tool that is valid and reliable for skeletally immature patients of all ages is not yet available. Further studies are needed to identify specific pediatric measurements to increase validity, responsiveness, sensitivity, and interpretability of upper limb functional outcome scores in common clinical practice.

The 'Hybrid method' for the treatment of congenital clubfoot.

BACKGROUND: The hybrid method combines the advantages of the Ponseti technique and of the French Physical Therapy method. The main goal of this study is to present our results on 139 consecutive newborns with clubfoot (n=212 feet) treated at our Institution with the hybrid method. METHODS: From May 2010 until August 2020, 139 consecutive newborns with congenital clubfoot (66 unilateral; 73 bilateral) were treated by the hybrid method protocol and were retrospectively reviewed. All patients were admitted via the maternity ward with their family and personal history records, i.e., parental age, parity, gender, birth weight, involved side and presence/absence of associated medical conditions. At birth, all clubfeet were graded in ascending order of severity according to Dimeglio et al.'s classification system. AP and lateral radiographs of each foot are taken every 5 to 6 months from age 6 months to 2 years, then once a year until age 4 years, to assess divergence between talus and calcaneus on both projections. RESULTS: The cohort counted a total of 100 boys (71.9%) and 39 girls (28.1%). Clubfoot was unilateral in 66 patients (47.5%) and bilateral in 73 (52.5%). All but 10 patients had idiopathic clubfoot deformity (92.8%). Mean number of casts per patient was 8 (range: 4-11). One hundred and thirty patients out of 139 underwent percutaneous Achilles tenotomy under general anesthesia (93.5%). Overall, tibialis anterior transfer was performed in 6/212 feet (2.8%), posterior release in 9/212 (4.2%) and medial release in 1/212 foot (0.05%). CONCLUSIONS: Our experience with the hybrid method has allowed us to constantly reduce the number of patients requiring surgery over the years, as well as the extent of surgical release. These results are encouraging, but larger cohorts of patients from different institutions and with longer follow up are needed to confirm our findings.

Functional outcome of displaced radial head fractures in children treated by elastic stable intramedullary nailing.

The objectives of this study were to retrospectively investigate the clinical and radiological outcomes of displaced radial head fractures in children treated by elastic stable intramedullary nailing (ESIN) and evaluate the functional outcome of these injuries using the short version of the Disabilities of the Arm, Shoulder and Hand outcome questionnaire (Quick DASH). A total of 24 patients (nine males and 15 females) fulfilled the inclusion criteria. The mean age at the time of injury was 10.7±2.8 years (range: 9.5-16.33 years). Before surgery, the mean angulation was 53.8°±18.4° (range: 28°-82°) differentiating fractures on the basis of Judet's classification. The mean Quick DASH score was a good 4 (range: 0-15.9). Functional outcomes were similar irrespective of the severity of fracture displacement (P>0.05), presence or absence of associated fracture (P>0.05), and time immobilized (P>0.05). The Quick DASH score was better in children younger than 9 years of age (1.62) than children older than 9 years of age (4.95), but without a statistically significant difference (P=0.058). Children with displaced radial head fractures treated with ESIN showed good functional outcomes. Associated fracture injuries were not a predictive factor of functional outcome. Open reduction must be avoided as it carries an increased risk of complications.

The hybrid method for the treatment of congenital talipes equinovarus: preliminary results on 92 consecutive feet.

Over the past 4 years, our pediatric orthopedic unit has developed a new hybrid protocol combining the advantages of Ponseti's method and the French functional physiotherapy method. Sixty-one patients (92 feet) completed treatment. Clubfoot was unilateral in 30 (49.2%) patients and bilateral in 31 (50.8%) patients. The mean Dimeglio score at the start of treatment was 13.5/20 (range: 6/20-19/20). All patients had clinical and radiographic follow-up for at least 2 years (range: 2-4 years). If orthopedic treatment was ineffective and feet showed no improvement, further surgery was performed. Posterior release was performed in eight (8.7%) feet. Clinical evaluation at the last follow-up found a mean dorsal flexion of 20°±5° (range: 5°-35°). The hybrid method is a combination approach applying the strengths of Ponseti's method, that is, serial casting, and the French physiotherapy method, that is, manipulations and radiographs, to achieve long-term correction with a foot that is fully functional and pain free.

Risk of infection and secondary displacement in pediatric supracondylar or lateral condyle fractures treated with unburied Kirchener-wires removed before complete bone healing.

This study evaluated the risk of infection and of secondary displacement among children with displaced lateral condyle or supracondylar fractures treated by surgery. The study included a consecutive sample of 84 supracondylar fractures and 21 lateral condyle fractures treated with closed reduction and percutaneous pinning. The mean time to Kirchener wire removal was 29 days (range: 25-37 days) postsurgery. Two out of 105 (1.9%) patients developed infectious complications and two of 105 (1.9%) patients had a secondary displacement. Removal of unburied Kirchener wires before complete bone healing in the physician's office does not increase risk of infection or the risk of secondary displacement. The protocol does, however, enable significant savings and eliminates the need for additional anaesthetic.

Evaluation of upper extremity function of displaced diaphyseal humeral fractures in children treated by elastic stable intramedullary nailing: preliminary results.

The aim of this study was to retrospectively evaluate the outcome of displaced humeral shaft fractures in children and adolescents treated by elastic stable intramedullary nailing (ESIN) and to evaluate upper extremity function using the Quick-DASH questionnaire. Correction was maintained over time in 14 of 16 patients. All patients were pain free at last follow-up. Shoulder and elbow ranges of motion were comparable with the noninjured side. The mean Quick-DASH score was 1. This study reports good functional outcomes in children with displaced humeral shaft fractures surgically treated with ESIN, even in the presence of residual deformity. ESIN enables stable reduction, good rotational control, and good functional outcome.

Serial elongation-derotation-flexion casting for children with early-onset scoliosis.

Various early-onset spinal deformities, particularly infantile and juvenile scoliosis (JS), still pose challenges to pediatric orthopedic surgeons. The ideal treatment of these deformities has yet to emerge, as both clinicians and surgeons still face multiple challenges including preservation of thoracic motion, spine and cage, and protection of cardiac and lung growth and function. Elongation-derotation-flexion (EDF) casting is a technique that uses a custom-made thoracolumbar cast based on a three-dimensional correction concept. EDF can control progression of the deformity and - in some cases-coax the initially-curved spine to grow straighter by acting simultaneously in the frontal, sagittal and coronal planes. Here we provide a comprehensive review of how infantile and JS can affect normal spine and thorax and how serial EDF casting can be used to manage these spinal deformities. A fresh review of the literature helps fully understand the principles of the serial EDF casting technique and the effectiveness of conservative treatment in patients with early-onset spinal deformities, particularly infantile and juvenile scolisois.
