Prevalence of Tympanostomy Tube Placement in Relation to Cleft Width and Type.

OBJECTIVES/HYPOTHESIS: The prevalence of tympanostomy tube surgery (TTS) in patients with a cleft deformity was investigated, in relation to cleft width and cleft type. STUDY DESIGN: Retrospective review of medical health records. METHODS: Retrospective review of medical health records. Seventy-eight patients with non-syndromic cleft deformity of the palate and/or alveolus and lip between 2003 and 2017 were investigated. All available medical documents were analyzed. The study group was divided into subgroups: 1) patients with isolated cleft palate (CP) and patients with a cleft palate with cleft lip and alveolus (CLP). 2) According to Veau's classification (I-IV), further subgroups were defined. Cleft width was measured using plaster cast models. RESULTS: TTS was performed in 55% of the patients (n = 43). Considering Veau's classification, TTS was conducted as follows: Veau I 65.2% (n = 15/23), Veau II 55.0% (n = 11/20), Veau III 47.6% (n = 10/21), and Veau IV 50.0% (n = 7/14). Cleft classifications, maxillary arch width, and absolute/relative cleft width had no statistical impact on TTS occurrence. Although no significant correlation could be found, patients in our study group with CP (Veau I and II) underwent TTS more often (60.5%, n = 26/43) than patients with CPL (Veau III and IV; 48.6%, n = 17/35) during a three-year follow-up. CONCLUSION: None of the cleft characteristics examined had a significant impact on the proportion of patients who received TTS. Nevertheless, patients with lower Veau classification and CP received tympanostomy tubes more often. Therefore, otolaryngologists and pediatricians treating children with cleft palate should maintain a high level of suspicion for chronic middle ear effusion, even in patients with small clefts.

Comparison of use of plaster casting versus elastic bandage following carpal tunnel release: a randomized controlled study.

OBJECTIVE: To compare the effects of two postoperative regimens following carpal tunnel release; plaster casting and elastic bandaging. DESIGN: A randomized controlled study. PATIENTS: Patients with carpal tunnel syndrome and planned surgical carpal tunnel release were invited to participate. METHODS: A total of 94 patients were randomized to either plaster casting or elastic bandaging to be used 2 weeks postoperatively. Muscle strength, pain rated on a visual analogue scale, range of movement, sensibility, oedema, and different scores regarding symptoms and function were measured before and 2, 4, 6, 8 and 26 weeks after surgery. RESULTS: No differences were found between the 2 groups for any measurement, except for the DASH (Disability of the Arm, Shoulder and Hand) Health Score and daily function, rated 2 weeks postoperatively, in which the bandage group scored better. Both groups improved significantly over time for all measurements, sensibility was improved after 2 weeks, while strength was not fully recovered until week 26. CONCLUSION: Following carpal tunnel release no benefits were found in using plaster casting, compared with elastic bandaging. Among these patients there was more discomfort during plaster casting compared with elastic bandaging; therefore plaster casting is not recommended following this type of surgery.

Commonly used adjuvants (liquid soap, foam sanitizer, or ultrasound gel) do not improve strength or curing time of fiberglass cast material.

BACKGROUND: Bone fractures are one of the most common injuries in the USA. Fiberglass tape is a commonly used casting material, and many medical professionals apply adjuvants including liquid hand soap, foam sanitizers, and ultrasound gel in the hopes of improving outcomes relating to ease of molding and eventual strength, lamination, and smoothness of cast material. However, the efficacy of these agents to improve fiberglass cast mechanics has not been scientifically evaluated. The purpose of this study was to assess the mechanical effects of commonly used adjuvants on fiberglass cast materials. METHODS: Studies compared regularly shaped samples of water-activated, untreated fiberglass tape (Ossur Techform Premium) to water-activated fiberglass tape treated with one of three commonly used adjuvants (liquid soap, foam hand sanitizer, or ultrasound gel) during lamination. Material stiffness, yield stress, and ultimate load were measured by 3-point bending. RESULTS: These studies demonstrated that that liquid soap and ultrasound gel did not affect fiberglass tape mechanical properties, but alcohol-based foam sanitizer significantly reduced stiffness (- 32.8%), yield stress (- 33.6%), and ultimate load (- 31.0%) of the cast material as compared to the control group. Regression slopes were not significantly different between groups, suggesting that no adjuvants improved material curing time. CONCLUSIONS: These data suggest that the application of adjuvants is not beneficial and potentially harmful to fiberglass cast behavior. Despite the widespread practice of adjuvant application by medical professionals during casting, results from the current study suggest that use of these agents for structural enhancement of fiberglass casts is not beneficial and should largely be discouraged.

BET 1: Functional treatment is non-inferior to below the knee cast in adults with acute closed proximal fifth metatarsal fractures.

A short cut review was carried out to establish whether functional treatment is better than conservative treatment with a below knee cast at decreasing time to functional recovery and fracture union in adults with an acute closed proximal fifth metatarsal fracture. Four papers presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. It is concluded that in proximal (zone 1 and 2) fractures of the fifth metatarsal functional treatment with immediate mobilisation is at least non-inferior to immobilisation in a cast.

Is Buddy Taping as Effective as Plaster Immobilization for Adults With an Uncomplicated Neck of Fifth Metacarpal Fracture? A Randomized Controlled Trial.

STUDY OBJECTIVE: We compare buddy taping with plaster casting for uncomplicated fifth metacarpal (boxer's) fractures. We hypothesize buddy taping will give superior functional outcomes at 12 weeks, defined as a 10-point difference on the Shortened Disabilities of the Arm, Shoulder and Hand (quickDASH) score. METHODS: This randomized controlled trial included patients aged 18 to 70 years, with uncomplicated boxer's fractures in 2 hospitals in Queensland, Australia. The intervention consisted of buddy taping of the ring and little fingers on the affected side, in which the control group received plaster casting. Primary outcome was hand function as measured by quickDASH score (0 to 100, with 0 indicating no disability) at 12 weeks. Secondary outcomes measured at 3, 6, and 12 weeks included time off work and activities, pain, satisfaction, and the EuroQol 5-Dimension 3-Level score (measure of overall health). RESULTS: Ninety-seven patients with primary endpoint data were available for analysis, 48 in the buddy taping group and 49 in the plaster group. At 12 weeks, median quickDASH scores were the same for both groups (buddy 0, interquartile range [IQR] 0 to 2.3; plaster 0, IQR 0 to 4; difference 0; 95% confidence interval of the difference 0 to 0). Patients in the buddy taping group missed a median 0 days (IQR 0 to 7) of work compared with the plaster group's 2 days (IQR 0 to 14). Other secondary outcome measures were the same in both groups. CONCLUSION: We found that patients with boxer's fractures who were randomized to buddy taping had functional outcomes similar to those of patients randomized to plaster cast at 12 weeks. We advocate a minimal intervention such as buddy taping for uncomplicated boxer's fractures.

[Clubfoot Therapy in Accordance with Ponseti - Current Standard]. / Klumpfußtherapie nach Ponseti ­ aktueller Standard.

This manuscript evaluates the recent standard concept for clubfoot treatment. With regard to the history of clubfoot therapy and the return to conservative methods, the focus is laid on Ponseti's treatment concept. Due to its development according to the precise analysis of the pathoanatomy, the practical principle is simple and easy to learn and consists basically of two redression maneuvers, percutaneous achillotenotomy, and boots and bar abduction treatment. Therefore, about 60 years after its implementation in Iowa it can be said to be the worldwide golden standard. It is known that Ponseti treated feet are better with regard to function and pain when compared to surgically treated clubfeet. The best results can be achieved when one sticks exactly to the method. Hence, plaster of Paris above the knee casts yield better results than fibreglass materials or short-leg casts. The brace should be worn 23 hours a day for 3 months and during sleep until the fourth birthday of the child. For reasons including the structured concept of treating relapses, the method is applicable in high and low income countries. Before transferring the tibialis anterior tendon, it is mandatory to correct the relapse of the heel varus. The Ponseti method can also correct clubfeet of non-idiopathic origin. Although a higher rate of relapses must be expected in these cases, initial Ponseti treatment lowers the extent of the necessary surgery. Emphasis is put on the importance of counselling prenatally as well as during the boots and bar period. To yield the best results, it is necessary to train and counsel physicians as well as parents. There is no need to fear significant delay in reaching motor milestones when clubfeet are treated conservatively. Other conservative methods - such as the French physiotherapy method - are able to correct the deformity, but usually do not consist of a concept as structured as the Ponseti method. They are also often more time consuming for the families when compared to Ponseti's technique and are not available ubiquitously. While the diagnosis of the clubfoot deformity is still a clinical one and scores are the main tools for grading the severity today followed by X-rays and to some extent sonography, in experimental settings MRI may be helpful in finding abnormalities in muscles, blood vessels, and cartilage structures. The study of genetic associations of pathway abnormalities and single nucleotide polymorphisms with regard to the development of clubfeet enhances our knowledge concerning the origin of the deformity during limb development. In the future, this may enable us to provide not only a better prognosis for the outcome but also a more individualised therapy for each child born with a clubfoot.

Clinical and radiographic comparison of single-sugar-tong splint to long-arm cast immobilization for pediatric forearm fractures.

The purpose of this study was to compare the efficacy of a single-sugar-tong splint (SSTS) to a long-arm cast (LAC) in maintaining reduction of pediatric forearm fractures, while avoiding secondary intervention. One hundred patients age 3-15 with a forearm fracture requiring a reduction and immobilization were evaluated (50 LAC and 50 SSTS). Medical records and radiographs were reviewed at injury, postreduction, and at 1, 2, and 4 weeks postinjury. Sagittal and coronal angular deformities were recorded. Any secondary intervention due to loss of reduction was documented. The groups were matched by age (P = 0.19), sex (P = 0.26), mechanism of injury (P = 0.66), average injury sagittal deformity (LAC 27.4°, SSTS 25.4°; P = 0.50), and average injury coronal deformity (LAC 15.5°, SSTS 16°; P = 0.80) At 4 weeks postinjury follow-up, there were no statistically significant differences between use of an SSTS or LAC when comparing postimmobilization sagittal alignment (LAC 10.3 ± 7.2, SSTS 8.4 ± 5.1°; P = 0.46), coronal alignment (LAC 6.9 ± 4.6, SSTS 7.6 ± 9.3°; P = 0.46), or need for repeat manipulation or surgery (LAC 4/50, SSTS 3/50; P = 0.70).

[Classification Systems to Evaluate the Clubfoot and Their Potential Use to Predict the Course and the Results of the Ponseti Method Treatment]. / Klasifikacní systémy hodnocení pes equinovarus congenitusa jejich mozné vyuzití v predikci prubehu a výsledku lécby Ponsetiho konceptem.

INTRODUCTION The clubfoot ranks among the most frequent paediatric structural deformities of the lower extremity. Currently, the Ponseti method is considered the gold standard for the treatment. To evaluate the degree and severity of the deformity, clinical classification systems have been developed, commonly used in clinical practice. This study aims to verify whether the Pirani and Dimeglio clinical scoring systems can be used to predict the results of treatment by the Ponseti method. MATERIAL AND METHODS The study included 31 patients. The patients had been referred from the neonatal departments to the Department of Paediatric Surgery, Orthopaedics and Traumatology in Brno with the diagnosed clubfoot deformity, where they were treated by an erudite orthopaedist experienced in this field according to the Ponseti treatment standards. The Pirani and Dimeglio clinical scoring of the deformity were performed always before the commencement of the therapy and after the second plaster cast fixation. The number of plaster cast fixations, the necessity to carry out achillotomy and the relapse rate were set as the parameters of treatment results. In the first stage of statistical analysis, the respective clinical systems were correlated with the treatment results, in the second part of the study the patients were based on the clinical evaluation divided into 3 groups depending on the severity of the deformity, and these groups were subsequently compared. RESULTS 22 patients from the group (71%) underwent percutaneous achillotomy and in 3 patients (9.7%) a relapse occurred. To correct deformities 7.1 corrective casts were used on average. The correlation between the number of plaster cast fixations and classification systems was significant in all the cases, with the strongest dependency shown by the correlation with the Pirani score after the second corrective cast (r = 0.594, p < 0.001). Positive correlation was found also between the necessity to perform achillotomy and both the classification systems. In this case the strongest correlation was established in the case of the Pirani clinical scoring after the second plaster cast fixation (r = 0.488, p = 0.003). Conversely, significant correlation was not established between the relapse rate and the used classification systems, not even in a single case (p ≥ 0.05). In the second stage of the statistical analysis, in the case of the Pirani scoring before the therapy no difference was found between the individual groups with diverse severity of clubfoot deformity during the evaluation of the aforementioned parameters of treatment results. In the Pirani classification after the second plaster cast fixation, a statistically significant difference was established in the number of plaster cast fixations (p = 0.003) and the necessity to perform achillotomy (p = 0.012). When the Dimeglio scoring was applied before the therapy, a statistically significant difference between the groups was found in the number of plaster cast fixations (p = 0.031) and after the second plaster cast fixation in the relapse rate (p = 0.035). DISCUSSION Although the clinical scoring systems belong to key indicators of severity of the deformity and are commonly used in clinical practice, the current literature provides only an inconsistent picture of their application in predicting the course and the results of treatment. Concurrently, the authors opinions on this issue differ. The scoring in later stages of treatment shows a better predictive value than the scoring at the beginning of the treatment, which was confirmed also by the results of our study. CONCLUSIONS Even though the clinical scoring systems show a certain dependency on the parameters of the treatment results, in practice their predictive function can be used to a limited degree only. The complexity of the evaluation of the deformity itself and subsequently of the results of treatment requires also the use of other parameters than the clinical classifications only so that the prediction of the course and results of the treatment of clubfoot according to Ponseti shows a higher degree of reliability. Key words:clubfoot, Ponseti, Pirani classification, Dimeglio classification.

A Quality Improvement Initiative Reduces Cast Complications in a Pediatric Hospital.

BACKGROUND: Casts, while frequently used as routine treatment in pediatric orthopaedic practice, are not without complications. At our large tertiary care pediatric hospital, the baseline rate of all casting complications was 5.6 complications per 1000 casts applied (0.56%). We tested the hypothesis that we could use quality improvement (QI) methodology to decrease the overall cast complication rate and improve patient care. METHODS: We initiated a QI program implementing concepts derived from the Institute for Healthcare Improvement models, including Plan-Do-Study-Act cycles, to decrease our cast complication rate. A resident casting education program was developed with a competency "checklist" to ensure that casts are applied, bivalved, and removed in a safe and standardized manner to prevent patient harm. AquaCast Saw Stop Protective Strips were required to be applied with every cast application. A review of our facility's processes and procedures determined adequate measures were in place to effectively manage inventory and maintenance of cast-saw blades. RESULTS: With the multimodal QI intervention, our cast complication rate was reduced to 1.61 complications per 1000 applications, a >90% improvement. CONCLUSIONS: Implementation of QI concepts to perform a QI initiative resulted in a shift toward fewer cast complications, leading to overall improved patient care at a large tertiary pediatric hospital. LEVEL OF EVIDENCE: Level II-prospective cohort study.

The efficacy of removable devices to offload and heal neuropathic plantar forefoot ulcers in people with diabetes: a single-blinded multicentre randomised controlled trial.

Non-removable offloading is the 'gold standard' treatment for neuropathic diabetic plantar forefoot ulcers. However, removable offloading is the common 'standard of care'. We compared three removable offloading devices for ulcer healing efficacy. In this multicentre, randomised controlled trial, 60 persons with neuropathic diabetic plantar forefoot ulcers were randomly assigned to wear a custom-made knee-high cast [BTCC (bivalved TCC)], custom-made ankle-high cast shoe or a prefabricated ankle-high forefoot-offloading shoe (FOS). Primary outcome was healing at 12 weeks. Dynamic plantar pressures, daily stride count and treatment adherence were assessed on a randomly selected subset (n = 35). According to intention-to-treat analysis, 58% of patients healed with BTCC [OR 0·77 (95% CI 0·41-1·45) versus FOS], 60% with cast shoe [OR 0·81 (95% CI 0·44-1·49) versus FOS] and 70% with FOS (P = 0·70). Mean ± SD peak pressure in kPa at the ulcer site was 81 ± 55 for BTCC, 176 ± 80 for cast shoe and 107 ± 52 for FOS (P = 0·005); stride count was 4150 ± 1626, 3514 ± 1380 and 4447 ± 3190, respectively (P = 0·71); percentage of 2-week intervals that patients wore the device <50% of time was 17·3%, 5·2% and 4·9%, respectively. Non-significant differences in healing efficacy between the three devices suggest that, when non-removable offloading is contraindicated or not available, each can be used for plantar forefoot ulcer offloading. Efficacy is lower than previously found for non-removable offloading maybe because suboptimal adherence and high stride count expose the patient to high repetitive stresses. These factors should be carefully considered in decision making regarding ulcer treatment.

Congenital talipes equinovarus and congenital vertical talus secondary to sacral agenesis.

Sacral agenesis is a rare congenital defect which is associated with foot deformities such as congenital talipes equinovarus (CTEV) and less commonly congenital vertical talus (CVT). We report a 3-year-old Caucasian girl who was born with right CTEV and left CVT secondary to sacral agenesis. Her right foot was managed with a Ponseti casting method at 2 weeks, followed by an Achilles tenotomy at 4 months. The left foot was initially managed with a nocturnal dorsi-flexion splint. Both feet remained resistant and received open foot surgery at 10 months producing plantigrade feet with neutral hindfeet. At 19 months, she failed to achieve developmental milestones and examinations revealed abnormal lower limb reflexes. A full body MRI was performed which identified the sacral agenesis. We advocate early MRI of the spine to screen for spinal defects when presented with resistant foot deformities, especially when bilateral.

Preliminary Report-The Long Leg Cast With a Pelvic Band: A Novel Approach to Treatment of Pediatric Femur Fractures.

OBJECTIVES: The aim of the study was to describe the long leg cast with a pelvic band (LLCPB), a novel alternative to spica casting for treating femur fractures in patients aged 6 months to 6 years which requires no casting above the waist, allows for hip flexion adjustments after it is applied, and does not require an operating room for placement. METHODS: Seven children aged 7.9 months to 3.7 years with femur fractures treated with the LLCPB at a single institution were retrospectively studied. All children were casted in the emergency department under conscious sedation. Radiographic and subjective outcomes were recorded. RESULTS: All 7 children achieved acceptable reduction of their fractures without the need for re-reduction or cast wedging. Five of the 7 children were discharged from the emergency department; 1 child required 1 night of hospitalization and another child required 2 nights of hospitalization. There were no complications. The cost of placing an LLCPB at our institution was $430.46. The cost of placing a spica cast in the operating room was $5427.54 to $6465.00. CONCLUSIONS: The long leg cast with a pelvic band seems to be an acceptable treatment for children aged 8 months to 4 years with spiral femur fractures. This technique has significant advantages over traditional and modified spica casts including allowing for uninhibited toileting, weight bearing on the unaffected leg, adjustment of hip flexion at any point after placement, and easier access to the perineum, abdomen, and chest for hygienic and medical purposes. Furthermore, treatment with an LLCPB presents significant potential for cost savings.

Cost analysis and performance in distal pediatric forearm fractures: is a short-arm cast superior to a sugar-tong splint?

The aim of this study is to compare splint versus cast immobilization for maintaining alignment following closed reduction of distal 1/3 radius and both-bone forearm fractures. We performed a retrospective review of patient records between 5 and 14 years old with a distal 1/3 radius or radius and ulna fracture requiring reduction. A cost comparison was also performed using facility costs for materials. Reduction was maintained with acceptable alignment in most cases (94%). Although a sugar-tong splint slightly maintained fracture alignment better, this was not significant. Cost analysis favored initial placement of a short-arm cast ($23.59) versus a splint with later cast conversion ($26.95). Pediatric patients with a distal 1/3 radius and/or both-bone fracture requiring reduction maintain postreduction alignment irrespective of the immobilization method used, but initial placement of a short-arm cast is more cost-effective.

It is not just comfort: waterproof casting increases physical functioning in children with minimally angulated distal radius fractures.

Waterproof casting has been reported to increase patient comfort and satisfaction, and decrease skin irritation. There are no available data on the influence of waterproof casting materials on physical function in pediatric patients. Our aim was to determine whether the use of waterproof casting would result in faster recovery of physical function while maintaining similar clinical outcomes as those obtained with nonwaterproof materials. Twenty-six children with nonangulated or minimally angulated distal radius fractures were assigned randomly to initially receive a short-arm cast made of one of two optional materials: a hybrid mesh material with a waterproof lining or fiberglass with a nonwaterproof skin protector. Two weeks later, the initial cast was removed and replaced with a short-arm cast made of the alternative option. We compared the rate of fracture displacement, physical function, pain, skin changes, itchiness, and patient satisfaction. No evidence of displacement was found in either group. The mean Activities Scale for Kids - Performance (ASK-P) (physical function) score was 10% higher during the period of time when a waterproof cast was used (P=0.04). When a waterproof cast was used during the first 2 weeks of treatment, the mean total ASK-P scores were 23% higher than that when a nonwaterproof one was used during the same period of time (P=0.003). Patients who received a waterproof cast as the initial treatment reported lower functional scores overall and in almost every domain of the ASK-P once they were in a nonwaterproof one; similarly, those who received a nonwaterproof cast as the initial treatment reported higher functional scores overall and in every domain of the ASK-P once they were in a waterproof cast. Compared with a nonwaterproof cast, the use of waterproof casting resulted in comparable levels of pain, itchiness, skin irritability, and overall patient satisfaction. The results of this randomized, cross-over trial suggest that the use of waterproof casting material for the treatment of nondisplaced or minimally displaced distal radius fractures in children can result in a faster recovery of physical function, while providing comparable stability, pain, itchiness, skin irritability, and overall patient satisfaction. LEVEL OF EVIDENCE: II.

Objective assessment of plaster cast quality in pediatric distal forearm fractures: Is there an optimal index?

BACKGROUND: Several so-called casting indices are available for objective evaluation of plaster cast quality. The present study sought to investigate four of these indices (gap index, padding index, Canterbury index, and three-point index) as compared to a reference standard (cast index) for evaluation of plaster cast quality after closed reduction of pediatric displaced distal forearm fractures. METHODS: Forty-three radiographs from patients with displaced distal forearm fractures requiring manipulation were reviewed. Accuracy, sensitivity, specificity, false-positive probability, false-negative probability, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were calculated for each of the tested indices. RESULTS: Comparison among indices revealed diagnostic agreement in only 4.7% of cases. The strongest correlation with the cast index was found for the gap index, with a Spearman correlation coefficient of 0.94. The gap index also displayed the best agreement with the cast index, with both indices yielding the same result in 79.1% of assessments. CONCLUSION: When seeking to assess plaster cast quality, the cast index and gap index should be calculated; if both indices agree, a decision on quality can be made. If the cast and gap indices disagree, the padding index can be calculated as a tiebreaker, and the decision based on the most frequent of the three results. Calculation of the three-point index and Canterbury index appears unnecessary.

Avaliação da concordância entre modelos ortodônticos digitais e de gesso com e sem apinhamento / Evaluation of the agreement between digital and orthodontic models with and without crowding

O objetivo deste estudo foi avaliar o grau de concordância entre modelos ortodônticos digitais e modelos ortodônticos de gesso com e sem apinhamento. A amostra foi composta por 116 modelos de gesso, sendo 50% com apinhamento e os outros 50% sem apinhamento. Todos eles foram escaneados através do aparelho Optical 3D (Open Technologies, Itália) gerando modelos digitais. Foram realizadas medidas do diâmetro mesiodistal (DMD) dos dentes e da soma de segmentos dos arcos dentários. Nos modelos físicos as medições foram feitas com paquímetro digital, já nos digitais foram feitas a partir do programa MeshLab, versão 1.3.4 BETA. A concordância entre os modelos ortodônticos digitais e de gesso foi avaliada pelo método de Bland-Altman e a hipótese de o viés ser ou não igual a zero foi verificada pelo teste t de Student para amostras emparelhadas. Foi adotado o nível de significância estatística de 5% e nível de significância clínica ≥ 0,5mm para DMD e ≥ 1,5mm para soma de segmento de arco. Apesar de existirem algumas diferenças estatisticamente significantes entre as medições realizadas nos modelos de gesso e os digitais com e sem apinhamento, as discrepâncias foram consideradas clinicamente não significantes para ambos. Conclui-se que as medições obtidas a partir de modelos digitais com ou sem apinhamento, gerados através do aparelho Optical 3D scanner (Open Technologies, Itália) e programa MeshLab®, são concordantes com as realizadas manualmente em modelos de gesso. Modelos 9 digitais podem ser uma alternativa clinicamente confiável para modelos de gesso na prática ortodôntica.(AU)

The objective of this study was to evaluate the degree of agreement between digital orthodontic models and orthodontic models of plaster with and without crowding. The sample consisted of 116 gypsum models, 50% with crowding and the other 50% with no crowding. All of them were scanned through the Optical 3D device (Open Technologies, Italy) generating digital models. Measurements were made of the mesiodistal diameter of the teeth and the sum of segments of the dental arches. In the physical models the measurements were made with digital caliper, already in the digital ones were made from the program MeshLab, version 1.3.4 BETA. The agreement between the digital orthodontic and plaster models was evaluated by the Bland-Altman method and the hypothesis that the bias was equal to zero was verified by Student's t test for paired samples. The level of statistical significance was set at 5% and clinical significance level ≥ 0.5mm for DMD and ≥ 1.5mm for sum of arc segment. Although there were some statistically significant differences between the measurements performed in the plaster models and the digital ones with and without crowding, the discrepancies were considered clinically not significant for both. It is concluded that the measurements obtained from digital models with or without crowding, generated by the Optical 3D scanner (Open Technologies, Italy) and 11 MeshLab® program, are in agreement with those performed manually in plaster models. Digital models may be a clinically reliable alternative for plaster models in orthodontic practice.(AU)

Transportation of children in spica casts in the USA.

The aim of this study was to report outcomes of a hospital restraint loaner program for transporting children treated with spica casts. Fifty-two patients were studied. Appropriate restraints were selected by a therapist, consisting of 17 E-Z-On vest, 17 hippo car seat, five spelcast device, four family owned car seat, and nine transported using an ambulance. The cost to the hospital for the restraints ranged from $150 to $750 and $1200 for ambulance transportation. A car seat loaner program is a practical model to provide safe patient care for children in a spica cast.

Quantitative biomechanical comparison of ankle fracture casting methods.

The incidence of ankle fractures is increasing rapidly due to the ageing demographic. In older patients with compromised distal circulation, conservative treatment of fractures may be indicated. High rates of malunion and complications due to skin fragility motivate the design of novel casting systems, but biomechanical stability requirements are poorly defined. This article presents the first quantitative study of ankle cast stability and hypothesises that a newly proposed close contact cast (CCC) system provides similar biomechanical stability to standard casts (SC). Two adult mannequin legs transected at the malleoli, one incorporating an inflatable model of tissue swelling, were stabilised with casts applied by an experienced surgeon. They were cyclically loaded in torsion, measuring applied rotation angle and resulting torque. CCC stiffness was equal to or greater than that of SC in two measures of ankle cast resistance to torsion. The effect of swelling reduction at the ankle site was significantly greater on CCC than on SC. The data support the hypothesis that CCC provides similar biomechanical stability to SC and therefore also the clinical use of CCC. They suggest that more frequent re-application of CCC is likely required to maintain stability following resolution of swelling at the injury site.

[Femoral shaft fractures in children under 3 years old. Current treatment standard]. / Femurschaftfrakturen bei Kindern unter 3 Jahren. Aktueller Behandlungsstandard.

INTRODUCTION: Femoral shaft fractures in children are a common injury. Operative treatment is recommended for children above 3 years of age. The question of this investigation was the current clinical standard for the treatment of femoral shaft fractures in children under 3 years old. MATERIAL AND METHODS: An e-mail questionnaire was sent to all clinics and hospital departments of the members of the German Society for Trauma Surgery and the German Society of Pediatric Surgery. RESULTS: Out of 775 clinics and departments, 121 participated in the survey (16 %). From 2011 to 2012 overall 756 femoral shaft fractures of children 3 years and younger were treated of which 375 (50 %) were stabilized with elastic stable intramedullary nailing (ESIN), 183 (24 %) with an overhead extension, 178 (23 %) with a plaster cast and 9 (1 %) with external fixation. Finally, operative treatment was used in 51 % compared to 49 % with conservative treatment. DISCUSSION: Obviously, operative treatment of femoral shaft fractures in children younger than 3 years is routinely used despite the fact that there is no evidential basis for this approach. There are good arguments for and against operative and conservative forms of treatment. Indications for operative treatment include multiple trauma, open fractures, body weight over 20 kg, child already free walking and lack of stable fixation with conservative treatment. To achieve more evidence for the existing recommendation of the American Academy of Orthopaedic Surgeons (AAOS) and the Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF, Working Group of the Scientific Medical Specialist Societies), further investigations are needed.
