Our aim was to investigate the relationship between urinary excretion of deoxypyridinoline (DPD) as a marker of bone resorption, and Perthes' disease. There were 39 children with Perthes' disease in the florid stage who collected first-morning urine samples at regular intervals of at least three months. The level of urinary DPD was analysed by chemiluminescence immunoassay and was correlated with the radiological stage of the disease as classified by Waldenstr?m, and the severity of epiphyseal involvement according to the classification systems of Catterall and Herring. The urinary DPD levels of a group of 44 healthy children were used as a control. The median urinary DPD/creatinine (CREA) ratio was significantly reduced (p < 0.0001) in the condensation stage and increased to slightly elevated values at the final stage (p = 0.05) when compared with that of the control group. Herring-C patients showed significantly lower median DPD/CREA ratios than Herring-B patients (p = 0.03). The significantly decreased median DPD/CREA ratio in early Perthes' disease indicated a reduced bone turnover and supports the theory of a systemic aetiology. Urinary levels of DPD may therefore be used to monitor the course of Perthes' disease. 相似文献

AIM: Different systems are used for total knee arthroplasty (TKA). Compared were a press-fit femur condyle replacement system with fixed tibial PE-inlay versus a rotating tibia component system with an emphasis on the early functional results. METHOD: Patient selection and the use of the Knee Society Score for this randomized and prospective study were based on the directives for TKA of the german Society for Orthopaedic and Trauma Surgery (DGOT). We examined the patients post-operatively after 1 week, 2 weeks, 6 weeks, 3 months, 6 months, and 1 year. RESULTS: After 6 weeks an increase of the total knee score could be seen in both groups. The total knee score of the rotating tibia component increased from 93.96 pre-operatively to 113.57 after 6 weeks, to 139.82 after 3 months, to 154.32 after 6 months, and to 159.65 after one year. The total score with the fixed PE-inlay increased from 79.75 to 111.5 after 6 weeks, to 128.25 after 3 months, to 134.08 after 6 months, and to 130.08 after one year. CONCLUSION: After 6 weeks the implant with the rotating tibia component showed a lasting higher score as compared to the implant with a fixed PE-inlay component using the same early rehabilitation and mobilization techniques. 相似文献

Correction of length discrepancies and angular deformities of the leg by Blount's epiphyseal stapling 总被引:3,自引:0,他引:3

The management of leg length difference (LLD) and angular deformities of the leg remains controversial. Numerous treatment options have been proposed over the past years depending on the patient's general condition, skeletal age, function, and degree and configuration of the deformity. Our retrospective study consisted of 48 patients with 58 legs treated between 1970 and 1991 by Blount's epiphyseal stapling to equalise length or correct angular deformity. After an average follow-up of 16.5 years, all patients with idiopathic bow-legs or knock-knees (n=12) and 71% of LLD caused by overgrowth (e.g. Klippel-Trenaunay syndrome) showed good and excellent results at skeletal maturity, whereas the results of the treatment of LLD with undergrowth of the leg and angular deformities due to trauma, infection or general dysplasia and malformation were fair to poor because of the difficulty in prediction of growth development and growth potential, allowing only for partial correction of the deformity. Besides the restriction of the stapling procedure due to the aetiology of the deformity, the age of the patients at the time of surgery is important, as it determines the complication rate of this technique (loosening or dislocation of staples). Thus Blount's epiphyseodesis should not be performed before the age of 9 years in girls and 11 years in boys. CONCLUSION: Blount's epiphyseal stapling can be recommended as a safe procedure with predictably good results in idiopathic angular deformities of the leg and leg length difference caused by overgrowth. 相似文献

Treatment of congenital spondyloptosis in an 18-month-old patient with a 10-year follow-up. 总被引:1,自引:0,他引:1
STUDY DESIGN: Case report. OBJECTIVES: To present the case of a patient with congenital spondyloptosis treated and followed over 10 years. SUMMARY OF BACKGROUND DATA: The surgical management of spondyloptosis in children is variably reported in the literature. Some authors propose that posterior fusion in situ is a safe and reliable procedure, whereas others suggest that reduction of the slipped vertebra may prevent some of the adverse sequelae of in situ fusion, which include nonunion, bending of the fusion mass, and persistent lumbosacral deformity. Many investigators advocate a combined anterior and posterior fusion using instrumentation. METHODS: At the time of the first symptoms an 18-month-old boy with congenital spondyloptosis of L5-S1 was referred to the authors' institution. Because of the progression of pain, neurologic disturbance, mild foot deformity, muscle contractures, and lumbosacral kyphosis, surgical intervention was undertaken. Operative intervention began with a resection of the L5 lamina and wide bilateral L5 nerve root decompression. This was followed by anterior subtotal resection of L5 and interbody bone graft of the morcelized vertebral body for fusion from L5 to S1. The next step was reduction of the spondyloptosis and stabilization by posterior instrumentation L2-S1 with a sacral Cotrel-agraffe device. RESULTS: The procedure achieved almost complete reduction of the spondyloptosis with near-normal restoration of lumbar lordosis allowing more physiologic lumbar spinal biomechanics. There were no neurologic complications. After surgery there was no suggestion of back pain or gait disturbance and no progression of any deformity. CONCLUSION: In the treatment of severe congenital spondylolisthesis a staged procedure of decompression, reduction, and instrumented fusion is recommended for those cases in which intervention is indicated. 相似文献

Adolescent idiopathic scoliosis is a common disease with an overall prevalence of 0.47–5.2 % in the current literature. The female to male ratio ranges from 1.5:1 to 3:1 and increases substantially with increasing age. In particular, the prevalence of curves with higher Cobb angles is substantially higher in girls than in boys: The female to male ratio rises from 1.4:1 in curves from 10° to 20° up to 7.2:1 in curves >40°. Curve pattern and prevalence of scoliosis is not only influenced by gender, but also by genetic factors and age of onset. These data obtained from school screening programs have to be interpreted with caution, since methods and cohorts of the different studies are not comparable as age groups of the cohorts and diagnostic criteria differ substantially. We do need data from studies with clear standards of diagnostic criteria and study protocols that are comparable to each other. 相似文献
