ObjectiveTo explore the diagnosis and treatment of incomplete Kawasaki disease.MethodsA retrospective analysis was applied in 39 children patients clinically diagnosed as Kawasaki disease.ResultsThirtynine cases were found to have a high temperature over 5 days( 100％ ),30 patients with bilateral conjunctival congestion (76.9％),28 cases with cherry pink and chapped lips( 71.8％ ),21 patients with erythema multiforme and erythra(53.8％ ),20 cases with hand-foot scleredema(51.3％ )and 10 patients with cervical lymphatic enlargement (25.6％).In addition to the high temperature,22 cases were found to have three classic clinical diagnostic characterstics(56.4％ ),and 17 patients with two classic characterstics(43.6％ ).During the course of disease,C-reactve protein was observed to increase,and erythrocyte sedimentation rate speed up significantly.Intravenous infusion of gamma globulin and oral administration of aspirin was confirmed to be effective for incomplete Kawasaki disease.ConclusionThe careful observation and complete clinical examination was conducive to early diagnosis of incomplete Kawasaki disease instead of misjudge and missed diagnosis.

Objective To retrospectively review long?term results of developmental dislocation of the hip patients treated with open reduction and Salter pelvic osteotomy, and to analyze the potential risk factors. Methods Sixty?eight developmental dislocation of the hip cases (81 hips) were treated with open reduction and Salter pelvic osteotomy from September 1992 to Octo?ber 2002, 45 cases (52 hips) were followed up to skeletal maturity. None had undergone other treatment before the key surgery. Some cases received skeleton traction before surgery. The radiographic and functional results were assessed at last follow?up. The possible relevant factors for unsatisfactory outcome were analyzed. The correlation between type ⅡAVN and the coverage rate of the femoral head were evaluated. Results The mean age at surgery was 2.5 years (ranged from 1.4 to 5.3 years). At last follow?up, 44 hips (84.6%) had excellent or good functional results. 23 hips (44.2%) had avascular necrosis of varying severity, of which 16 hips were typeⅡ. There was significant relevance between the AVN severity and the Severin classification result (P=0.018). Theover correctionhips, that were overcorrected during surgery, were more likely to get severe type AVN ( P=0.037). There was no correlation between TypeⅡAVN with uncoverage according to CE angle and Reimers index (P=0.457, 0.308 respectively). Con?clusion 1) Satisfactory functional and radiographic results could be expected in developmental dislocation of the hip cases with?out AVN;2) High risk of AVN existed in the late diagnosised hips that underwent open reduction and Salter pelvic osteotomy, typeⅡwas the most common type;3) TypeⅡAVN was not a predictor for progressive femoral head coverage deficiency;4)Over cor?rectionin Salter pelvic osteotomy was related with severe type AVN which should be avoided.

Objective To compare the early treatment results of Pavlik harness and closed reduction plus spica cast?ing in treating developmental dislocation of the hips (DDH). Methods The patients with GrafⅢ/Ⅳtype DDH diagnosed by ul?trasound in our hospital were analyzed retrospectively from January 2009 to December 2013. The subjects with intact clinical and radiologic data and more than 2 years follow?up were included. The present study included 257 patients (298 hips), 31 male and 226 female, with the average age of 74.1±39.2 d (from 30 to 159 d). Pavlik harness underwent in 190, while 67 cases were treated with closed reduction plus spica casting. Acetabular index (AI), Wiberg OE angle (point O was the middle point of proximal me?taphyseal border) and Smith instability index (SI, SI?c:the lateral displacement index, SI?h:the vertical displacement index) on the pelvic X?ray film at 2-3 years of age after successful early treatment were recorded. Femoral head avascular necrosis (AVN) was diagnosed according to the Salter criteria. Results The success rate of reduction of closed reduction was significantly higher than Pavlik harness (97.5% vs. 69.9%, χ2=0.353, P=0.000). There was no significant difference in the incidence of AVN be?tween the closed reduction and Pavlik harness (6.6% vs. 4.6%, χ2=0.106, P=0.745). For GrafⅢ type DDH, the success rate of reduction of Pavlik harness and closed reduction were 80.7% and 98.4% respectively (χ2=11.248, P=0.001), while the Pavlik harness group had significantly worse results of AI, OE and SI?c at the age of 2-3 years (Pavlik harness: 22.9°±3.7°, 16.5°± 6.3° and 0.74 ± 0.06; closed reduction: 21.4° ± 3.4° , 18.9° ± 3.6° and 0.72 ± 0.03; P<0.05). For GrafⅣ type DDH, the success rate of reduction of Pavlik harness was much less than closed reduction (25.6% vs. 94.4%, χ2=24.231, P=0.001), with signifi?cantly worse results of OE at the age of 2-3 years (16.0°±4.1° vs. 18.6°±4.5°, t=-2.141, P=0.038). Conclusion Pavlik har?ness has limitations in treating GrafⅢ/Ⅳtype DDH, with lower success rate of reduction for GrafⅣtype DDH. Closed reduction plus spica casting has better clinical results than Pavlik harness in success rate of reduction and subsequent hip development with? out the additional risk of AVN.

Objective To analyze the prevalence of developmental dysplasia of the hip (DDH) in Tianjin,and to establish early screening of DDH in China.Methods System of health care for maternity and children in Tianjin were used to perform early ultrasound-screening program for DDH during the first 6weeks of life.The infants with abnormal conditions or suspected ultrasound results were transferred to Tianjin hospital.All the infants were clinically examined by experienced pediatric orthopaedic physician.Anteroposterior pelvic X-rays were taken for suspected infants to make a definite diagnosis.Results Hip ultrasound examinations were performed for 94 443 infants between December 26,2009 and December 25,2010.The 136 cases (165 hips) were suspected as DDH and 168 cases (200 hips) were diagnosed as DDH by ultrasound.All of them were transferred to Tianjin hospital.Among suspected patients,the positive signal of Ortolani or Barlow was found in 10 cases (11 hips).The DDH signal on the radiograph was positive in 73 cases (84 hips).Two hundred and fifty-one infants (295 hips) were finally diagnosed as DDH.There were 40 boys and 211 girls.Also,left hips and infants bom in autumn or winter were more often involved.The prevalence of DDH in Tianjin area was 2.66% (251/94 443).Conclusion Accurate early detection and diagnosis of DDH could be expected with the Tianjin pattern of preliminary screening,secondary screening and definite diagnosis.Careful clinical examination and X-ray are important for diagnosis.

Objective To evaluate the effect of greater trochanteric transfer for the treatment of coxa brevis in children and adolescents.Methods From August 2005 to January 2011,twenty patients (22 hips)with coxa brevis underwent greater trochanteric transfer.Among them 18 patients (20 hips) were available for evaluation,including 4 boys and 14 girls,with an average age of 11.4 years (range,7.5-15.0 years) at operation.Five cases (6 hips) were caused by Perthes disease,and 13 cases (14 hips) were caused by developmental dysplasia of hip.Four patients (4 hips) had undergone greater trochanteric epiphyseodesis ever before.All patients were fixed with tension screw after the deformity was corrected during the operation.After operation,the human plaster spica was used for 6 weeks in all patients.Results All patients were followed up for 14 to 79 months (average,31 months).At the last follow-up,fatigue or pain in the hips disappeared or improved in 13 patients.Sixteen patients had limping and positive Trendelenburg sign preoperatively,at the last follow-up 9 patients got improvement.Twelve patients (13 hips) had limitation of abduction of the hip,the average range of abduction was 25.38°±1.20°,which was improved to 45.38°±1.05° at the last follow-up.The average articulotrochanteric distance and ratio of the distance from the greater trochanter tip to femoral head center and the radius of the femoral head at the last follow-up was (17.47+3.14)mm and 2.10±0.21,respectively,there were statistical differences compared with those before operation [(-2.89±4.62) mm and 1.59±0.22,respectiovely].The average leg-length discrepancy at the last follow-up was (0.78t±0.26) cm,which had on statistical differences compared with that [(0.83 ±0.33) cm]before operation.Conclusion Greater trochanteric transfer for the treatment of coxa brevis in children and adolescents could improve the clinical symptom,recover the normal anatomy of the proximal femoral,restore the hip biomechanics environment,but could uot improve the leg-length discrepancy.

Objective To determine the etiology and clinical characteristics of children with dilated cardiomyopathy.Methods 112 children with DCM from January 2002 to December 2011 were studied.The age,cause and the clinical manifestations were analyzed.According to the children with heart function,they were divided into four groups,the incidence and type of arrhythmia were compared.Results In 112 cases of DCM in children,＜ 1 year old diagnosed 52 cases (46.42％),107 cases (95.53％) with heart failure,25 cases (22.32％) with chear causes,96 cases(85.71％) children with a variety of arrhythmias.According to cardiac function in Ⅰ,Ⅱ and Ⅲ and Ⅳ level,they were divided into four groups.The incidence of one kind of arrhythrnia were 20.00％,31.25％,36.17％ and 42.85％.The incidence with two or more kinds of arrhythmia was 0,18.75％,38.29％ and 50.00％ respectively.The incidence of malignant arrhythmia was 0,12.50％,40.42％and 67.85％ in different groups.There was significant differences among the groups of Ⅱ and Ⅲ and Ⅳ level (P ＜ 0 05).Conclusion Children with dilated cardiomyopathy disease younger than I year old had the highest incidence.The major causes were myocarditis,hereditary and congenital metabolic diseases.The incidence of arrhythmia in DCM were high and diverse,often exist for a variety of arrhythmia,and arrhythmia have closely relation with heart function.The embolism in children with DCM was very rare.

Objective To evaluate the outcome of Titanium Elatic Intramedullary Nail (TEINs) for treatment of lengthunstable femoral shaft fracture of children.Methods Retrospectively analyze the data of total of 21 children with length-unstable femoral shaft fractures,from December 2011 to June 2014,were treated with TEINs and end caps.This study involved 15 boys and 6 girls,with age ranged from 5 years and 6 months to 10 years and 10 months,whose average age was 7 years and 5 months.Firstly children were treated with traction for 3-7 days,with traction weight of 1/4 to 1/6 of the weight.After that,shortening and angular deformity were significantly corrected.Then surgeries of close reduction and internal fixation with TEINs were done in general anesthesia.TEINs were supported with double nail C shape.The lateral tip of TEIN located near the epiphyseal plate of greater trochanter,and the medial tip near the epiphyseal plate of femur head.Cut the tail of TEINs,set and screw the end caps into cortex,keeping the tail of TEINs and fracture fixed.Spica casting was used for 4 weeks after operation.The last follow-up time was 2 years,and the follow up results were analyzed.Results 21 children were followed up ranged from 22 to 26 months,with the mean follow up 23.4 months.Remove the spica casting and bear loading at 4 weeks after operation.All fractures healed,with healing time of 5 to 8 weeks (an average of 6.2 weeks).At the last follow-up,the limb force line was good with no angular deformity.Femur overgrew 4.2-21.1 mm,with an average of 6.1 mm.At the last follow-up,the patients were evaluated with Harris score,and the excellent and good rate was 100％.No case of TEINs push-out,limited hip mobility,fracture nonunion,delayed healing or other complications was found.Only 1 case got a mild lameness.All parents were satisfied with their outcome.Conclution TEINs and end caps are effective methods for the length-unstable femoral shaft fracture in children.These results indicated that the risk of TEINs push-out can be reduced.

Objective To retrospectively analysis the clinical effect of temporary hemiepiphysiodesis for treatment of genu varus and valgus with pathologic physis in children.Methods All of 31 children (52 knees) were included in the study from January 2008 to December 2014,20 boys and 11 girls,the age at the time of surgery from 2 year 4 month to 13 year 4 month,mean 6 year 5 month.12 varus and 19 valgus,10 unilateral and 21 bilateral,41 femurs and 44 tibias.The Mechanichal Axis Deviation (MAD) was evaluated and the mechanical lateral distal femur angle (mLDFA) and medial proximal tibia angle (mMPTA) pre-operation and post-surgery was measured.Judging the efficacy with zone system for assessing mechanical axis based on Stevens,we think the results was satisfactory if the mechanical axis falls in zone ± 1 when removed the eightplate and other was unsatisfactory.We made statistical analysis of children who were corrected satisfactory and observed the change of the width and appearance of the physis.We also made the univariate analysis and Logistical multivariate regression analysis about sex,unilateral or bilateral,surgery age,femur or tibia,varus or valgus and severity of deformity to judge the influencing factors between satisfactory and unsatisfactory.We recorded the knee function and deformity recurrence at last follow up.Results The follow-up period was 2 year 6 month to 9 year 5 month,mean 4 year 1 month,44 knees (84.6％) were corrected satisfactory.The mean value of MAD at pre-surgery and at the time when the plate was removed were (-33.3t7.2) mm and (2.1 ±4.3) mm,mean mLDFA were 102.9°±4.9° and 85.3°±3.8°,mean mMPTA were 81.2°±3.4° and 90.5° ±4.4° in genu varus (21 knees);The meam value of MAD at pre-surgery and at the time when the plate was removed were 29.3±6.8 mm and-4.1±6.5 mm,and the mean mLDFA were 79.5o±5.7° and 88.1°±3.5°,mean mMPTA was 97.0°±4.3° and 87.1°±5.2° in genu valgus (23 knees),which were significant difference.There were 28 knees with physis width asymmetry in the 44 knees pre-operation and improved obviously after-surgery and the appearance became normally.8 knees corrected unsatisfactory included 2 varus and 6 valgus.The severity of deformity was a risk factor that affects efficacy with univariate analysis(t=5.124,P=0.000).Regarding the range of the age,we also did the logistic multivariate regression analysis with results showing that surgery age (OR=1.032) and se verity of deformity (OR=1.335) were related to the outcome.There were 8 knees in the 44 knees which had deformity recurrence and the rate was 19.5％ (8/41,3 knees excluded due to doing the limb lengthening surgery when removing the plate) at last follow up,and the knees function were normal.Conclusion Temporary hemiepiphysiodesis is a minimally invasive and effective method for treatment of genu varus or valgus with pathologic physis in children and could improve the appearance of the physis.The age at surgery and severity of deformity are the risk factors that affect efficacy.The pathological changes persisted could cause complication and deformity recurrence which need follow-up after removal of the plate.

Objective:To analyze the risk factors of avascular necrosis (AVN) after closed reduction and spcia casting in treating developmental dysplaisa of the hip (DDH).Methods:The patients with DDH who received closed reduction in our department from January 2016 to December 2017 were retrospectively reviewed. The inclusion criteria included aged at reduction ≥6 months, achieving successful reduction, having complete data with more than 2 years follow-up. A total of 48 cases with 54 hips were included in the present study. Among them, there were 2 males and 46 females, 41 unilateral hips and 13 bilateral hips. The mean age at closed reduction was 16.4±3.8 months (range 6-24 months). The mean follow-up duration was 2.9±1.8 years (range 2.3-4.1 years). Closed reduction was conducted under general anesthesia followed with a spcia cast immobilization. The abduction angle of the cast was recorded. The stability of reduction was evaluated by Ramsey safety zone. The maximum abduction and re-dislocation abduction were recorded. The quality of reduction was evaluated by the medial gap and femoral head coverage on intraoperative arthrography and post-reduction MRI. AVN was diagnosed according to Salter criteria. The risk factors of AVN were analyzed by univariate and binary logistic regression analysis.Results:AVN occurred in 12 hips (22.2%) of 54 hips. International Hip Dysplasia Institute (IHDI) grade and the difference between maximum abduction and cast abduction (Max-Cast abduction) were related to the occurrence of AVN in univariate analysis. The incidence of AVN in hips of IHDI grade 4 (42.9%, 9/21) was significantly higher than that in hips of IHDI grade 3 (9.7%, 3/31) (χ 2=6.007, P=0.018). However, the hips of IHDI grade 3 and 2 (0%, 0/2) presented a similar incidence of AVN (χ 2=0.000, P=1.000). The Max-Cast abduction was -0.7°±5.9° in the AVN group and 6.1°±7.6° in the AVN group ( t=2.125, P=0.038). Finally, IHDI grade ( OR=8.256, P=0.015) and Max-Cast abduction ( OR=0.832, P=0.047) were both independent factors of AVN in multivariate analysis. Conclusion:Most of the hips with AVN are IHDI grade 4 after closed reduction for DDH. The abduction angle in a spica cast could not be significantly related to the occurrence of AVN. However, the risk of AVN might be increased when the cast abduction is close to or beyond the maximum abduction. Safe abduction in the cast should be 5 to 10 degrees less than maximum abduction at least.
