Legg-Calve-Perthes disease: Catterall classification

The Catterall classification for Legg-Calvé-Perthes disease is based on radiographic appearances and is as follows: Group I: involvement of the anterior epiphysis only Group II: involvement of the anterior epiphysis with a clear sequestrum Group III: only a small part of the epiphysis is not involve 1.

[Article in German Published 2019 Classifications established for Legg-Calve-Perthes disease (LCPD) may be divided into three categories: Those defining the stage of the disease, those attempting to prognosticate outcome, and those defining outcome The aim of our study to is validate the role of Catterall classification in grading the disease preoperatively and prognosticating its outcome and categorising the post op outcome by Catterall postoperative scale. Materials & methods

The Catterall classification is based on the amount of femoral head involved during fragmentation (Catterall,1971): I - anterior epiphysis only area involved II - anterior and central epiphysis involved III - everything but the most medial and lateral epiphysis involve We reviewed the radiographs of 76 patients (76 hips) with Perthes disease for the results of treatment with abduction brace in order to compare the predictive value of the Catterall classification and the lateral pillar classification. The average age at onset was 6.9 years, and the length of follow-up was 8.2 years. All hips were evaluated by the Catterall classification and lateral pillar. - Catterall classification (3, 9) (Figure 11) (Table 3). It is the oldest classification (1971) and encompasses 4 stages, each of which is associated to a prognostic value (9). In 2008, a modified Catterall classification was proposed, due to poor reproducibility of the original one (6). It joins stage onsethavebeenproposed.Catterall[3]wasthefirsttopublish a widely accepted prognostic classification in 1971. This system described four categories based on the location of involvement of the femoral head as viewed on AP and lateral radiographs. In 1984, Salter and Thompson [22]proposeda two-category system based on a review of 1057 children wit Legg-Calve-Perthes Disease is an idiopathic avascular necrosis of the proximal femoral epiphysis in children. Diagnosis can be suspected with hip radiographs. MRI may be required for diagnosis of occult or early disease. Treatment is typically observation in children less than 8 years of age, and femoral and/or pelvic osteotomy in children.

Patients are placed in one of four groups based on the specific effects of Perthes on the epiphysis (growth center). The presence of collapse, degeneration, absorption, and regeneration are described with this system Catterall classification: epiphyseal involvement and head-at-risk signs This classification system provides diagnostic and prognostic criteria based on anteroposterior radiographs only. It compares the lateral pillar of the affected side with the intact contralateral side. The criteria are easy to define and there is better interobserver. Fifty hips in forty-four children with Legg-Calvé-Perthes disease, treated at the Shriners Hospital for Crippled Children, San Francisco, were evaluated with a simplified method of Catterall's classification. Our data indicate that the Catterall rating changed in 40 per cent of the hips when they were classified before they had reached the fragmentation stage of Waldenström compared with.

Interpretation - The Catterall classification and the original lateral pillar classification had sufficient interobserver agreement and association to late radiographic outcome to be suitable for clinical use. Adding the borderline B/C group did not increase the interobserver agreement or prognostic value of the original lateral pillar. We investigated the potential prediction of several classification systems by Kruskal-Wallis rank sum test and Nemenyitest, including Catterall Grouping, Herring Lateral Pillar Sign, Waldenström classificationand so on. Results: The clinical effective rate in modified Stulberg classification (type I & II) was 85.4% and the excellen The Catterall classification demonstrated overall a better predictive value for the Herring system. Instead, the most satisfactory reproducibility seems to be that of Herring: 80% as compared to 42% for the Catterall classification. Citations & impact . Impact metrics. 3 Citations The Catterall classification was developed to be applied in the fragmentation phase, which results in difficult and inaccurate initial assessment in early phases. Grouping tended to change if the classification was applied too early. Another criticism has been the lack of sufficiently high levels of interobserver agreement Inclusion criteria were: Catterall classification on plain radiography grade 2 (n = 4) or grade 3 (n = 8); unilateral LCP in order to allow comparison with the unaffected contralateral side that formed the control group; and the age at presentation more than 5 years of age.A senior paediatric orthopaedic surgeon initially saw all patients (VDR)

Initially, the classification system that most polarized the attention of other authors in the orthopedic literature was the one proposed by Catterall in 1971. 3 This author radiographically assessed the behavior of the nucleus of ossification of the femoral head during the progression of the disease, at the phase of maximum fragmentation The Catterall classification system is used widely but there has been some criticism. Because the classification is based on the epiphyseal involvement at the time of maximum resorption, which occurs relatively late, the grouping will appear to change if the classification is applied too early . An assessment using the Catterall classification.

Three main classification systems were proposed by Catterall, (8 Salter and Thompson 7 and Herring. ( 9 ), ( 10 Despite the relevance of these classification systems to estimate the disease severity, it also requires a reliable classification system to determine the disease stage, since the intervention time may have a material effect on the. Catterall classification: epiphyseal involvement and head-at-risk signs [54] A radiographic classification of severity based on the epiphyseal involvement on anteroposterior and lateral radiographs. This classification system has a high intra- and inter-observer variation. There are 4 groups based on the geometric epiphyseal involvement Catterall Classification: Group I • involvement of the anterior epiphysis only. Group II • involvement of the anterior epiphysis with a central sequestrum : Group III • only a small part of the epiphysis is not involved: Group IV • total head involvement : Based on degree of head involvement; At risk signs (indicate a more severe. The hips were grouped according to the Catterall classification, based on conventional radiographs: 5 hips were classified as group I; 15 as group 11; 23 as group 111; and 58 as group IV. The examinations were divided into 5 groups according to period of time after diagnosis, and each examination was sub-.

Reliability and stability of three common classifications for Legg-Calvé-Perthes disease hi The Catterall classification was used to determine the extent of involvement of the femoral head epiphysis at the time of diagnosis based on the radiographs and separately based on the MR images (3). The Catterall classification was retrospectively determined by consensus of three reviewers who were blinded to the results of the follow-up. Japan's largest platform for academic e-journals: J-STAGE is a full text database for reviewed academic papers published by Japanese societie This lateral pillar classification, when determined in the fragmentation phase, is of greater prognostic value and has a greater inter-observer reliability than the Catterall classification (8. The most common classification systems for moderate LCPD are as follows: the Catterall classification, 1) which associates the extent of the epiphyseal necrosis and prognosis; the Salter-Thompson classification, 11) which is a two-group classification of the extent of involvement of the femoral head according to the extent of the subchondral.

Sodium Channel Classification and Nomenclature. A variety of different sodium channels has been identified by electrophysiological recording, biochemical purification, and cloning (Goldin, 2001).The sodium channels are members of the superfamily of ion channels that includes voltage-gated potassium and calcium channels (Yu and Catterall, 2004); however, unlike the different classes of.

practical classification system must be reproducible, relying on landmarks that are only minimally affected by the disease process. It must accurately group similar hips so that treatment outcomes may be compared. Catterall system of classification of LCPD is one such classification system which categorizes, prognosticates, and dictates th According to the Catterall classification , two hips were in group II (50% involvement of femoral head with sparing of the lateral border), five hips were in group III (75% involvement of femoral head with lateral head significantly involved and collapsed), and three hips were in group IV (total femoral head involvement). In accordance with the. Regarding the radiological picture, we found that Catterall classification was used most of the times (64%), followed by Salter-Thompson (27%) and Herring (9%). We concluded that the baseline clinical status of these patients is similar to what is found in literature, with pain, limping, and decreased range of motion of the hip involved
