Accurate and reliable radiographic classifications of the relative severity and outcome of Legg-Calve-Perthes disease are essential in the study of that disease. Class I and II hips retain a spherical femoral head shape, class III began to see a shift towards an ovoid shape, and class IV and V hips demonstrate a flat shape. It is generally assumed that this system has an acceptable degree of reliability. According to Herring classification, four patients were in group B (9.3 %), one patient in group B/C (2.3 %) and 38 patients in group C (88.4 %). Class one is represented by a normal hip radiographically and a spherical femoral head. In comparison to the non-operated side, the MRI of previously operated hips showed no difference of version at the center of the femoral head but significantly . Table 1 Stulberg classification. However, we were concerned with regard to the authors' interpretation of the classification and the effect that this may have had on the reliability coefficients obtained. The control group consisted of symptomatically treated patients. This is a comment on "Stulberg classification system for evaluation of Legg-Calvé-Perthes . This classification is the reference standard for predicting the long-term outcome at skeletal maturity. Ficat and Arlet first classified avascular necrosis of femoral head (AVN) in 1964 before the advent of MRI which was later modified and published in 1985 to include pre-radiographic stages relying on invasive testing procedures.

It is generally assumed that this system has an acceptable degree of reliability. American Volume, 01 Oct 2000, 82(10): 1517 DOI: 10.2106/00004623-200010000-00040 PMID: 11057493 . Materials and methods: Ten children (11 hips) diagnosed with LCPD who had To note, in early disease, radiographic findings may be absent or nonspecific. Stulberg classification - RP's Ortho Notes RP's Ortho Notes Tag: Stulberg classification Legg Calve Perthes Disease January 7, 2019 3 Comments Legg Calve Perthes disease (LCPD) is a self-limiting condition caused by temporary interruption of blood supply to the growing proximal femoral epiphysis leading to necrosis, collapse and revascularization. Only 15 % had closure of one or both triradiate cartilages and only 14 % had closure of one or both proximal femoral physes. The short-term outcome of the disease was assessed in patients who reached the healed stage (stage IV) using the Mose criteria and the modified Stulberg classification system [21,22,23]. This result suggests that severity of femoral head deformation or degree of intraoperative varus angulation is not a key factor in leg length discrepancy. One patient, who had a bilateral Legg-Calvé-Perthes disease, underwent total hip . SD Stulberg, DR Cooperman and R Wallensten € € The natural history of Legg-Calve-Perthes disease This information is current as of January 7, 2007 Reprints and Permissions Permissions] link. Several prognostic classification systems for use at disease onset have been proposed. Stulberg grading At the final follow up, nine cases reached the healed stage of the disease. [3] have reported excellent inter- and intra-observer reliability, whereas Neyt et al. as a basis for treatment decisions during the active phase of Legg-Calve-Perthes disease because of its putative utility as a predictor of long-term outcome. In order to evaluate acetabular development and femoral head coverage, acetabular angle (AA), [] center-edge angle (CEA), [] Stulberg classification, [] and femoral head coverage [18, 19] were measured on the latest radiograph or on the radiograph taken just before any operation that would have changed these parameters.For statistical analysis, one hip was randomly selected on radiographs . Researchers and clinicians commonly use the classification system of Stulberg et al. Based on the radiographic crescent sign, we can distinguish:. Plain radiographs were used in order to obtain the Stulberg classification. RESULTS: When examining the outcome using the Stulberg classification system, there were 8 Stulberg class I hips (19.5%), 15 Stulberg class II hips (36.6%), 8 Stulberg class III hips (19.5%), 9 Stulberg class IV hips (22%), and 1 Stulberg class V hip (2.4%). JISRF CLASSIFICATION SYSTEM FOR SHORT STEM UNCEMENTED THA By: Timothy McTighe* S. David Stulberg , Louis Keppler , John Keggi , Robert T. Kennon , Declan Brazil*,**, Tony Aram , Ed McPherson , & TSI™ Study Group Members** Abstract: The aim of this paper is to review the influx of short stems for total hip arthroplasty. Catterall [ 3] was the first to publish a widely accepted prognostic classification in 1971. Chell J, Flowers MJ. Focus has shifted now to using the Herring (lateral pillar approach) because it has . Patient-related outcome measures included the international Hip Outcome Tool and Euroqol-5 dimensions scores. Stulberg classification. Stulberg classification [1]. Corresponding author: Stuart L. Weinstein, M.D., Department of Orthopaedic Surgery, University of Iowa Hospitals and Clinics, 200 Hawkins Drive, Iowa City, Iowa 52242-1009 Avascular necrosis (AVN) after pediatric femoral neck fracture (PFNF) showed poor prognosis, but its clinical and radiographic characteristics remained unclear. In Group C, the majority of femoral heads became aspherical in both age groups (29% Stulberg II, 52% Stulberg III, and 19% Stulberg IV results). 5). as a basis for treatment decisions during the active phase of Legg-Calvé-Perthes disease because of its putative utility as a predictor of long-term outcome. It is generally assumed that this system has an acceptable degree of reliability. There are five classes within the Stulberg classification. Stulberg classification Gold standard for rating residual femoral head deformity and joint congruence Recent studies show poor interobserver and intraobserver reliability Presentation Symptoms insidious onset may cause painless limp intermittent hip, knee, groin or thigh pain Physical exam hip stiffness loss of internal rotation and abduction The classification system later underwent further modifications . This is the stage where Stulberg radiographic classification is applied. article, or locate the article citation on jbjs.org and click on the [Reprints and It shows the shape of femoral head and its relations to acetabulum. A systematic review and a retrospective study were performed to evaluate the clinical and radiographic characteristics of patients with AVN after PFNF. These results appear to be better than the natural history as described by Stulberg. The Stulberg and Mose classification concerns the radiographic changes of the hip at maturity [31,32]. DI is a validated and robust tool developed specifically for the assessment of femoral head roundness in unilateral PD.8 Using an AP radiograph of the pelvis, the DI compares the affected hip to the unaffected side, providing a continuous variable that correlates well with long-term outcome using the Stulberg classification,22 the standard . The Stulberg classification method has been tested, modified, and eventually expanded to include five groups instead of the original three. Herring subsequently amended the original classification to include a B/C group in whom the amount of femoral head collapse was 50% of the original height. Stulberg classification. It is designed to attach directly to the operating table utilizing the existing table adapters. Results. Stulberg's classification for 23 hips presenting under the age of 6 years, with an average or poor outcome (Stulberg III, IV), was recorded at skeletal maturity. A The study looked for associations linking outcomes to residual . Expand. Herring JA, Kim HT, Browne R. Legg-Calve Perthes disease. All patients were treated by bracing at the Texas Scottish Rite Hospital from 1970 to 1980. SD Stulberg, DR Cooperman and R Wallensten € € The natural history of Legg-Calve-Perthes disease This information is current as of January 7, 2007 Reprints and Permissions Permissions] link. groups mature hips by shape of the femoral head and congruency in the joint and is the most widely used outcome measure [ 11, 23 ]. After the operation, patients were evaluated with Stulberg classification, and good outcome (Stulberg I/II) was achieved in 23 patients (53, 5 %), fair outcome (Stulberg III) in 16 patients (37, 2 % . An impressive 97 % of patients returned for follow-up at 5 years. Patients with more head-at-risk signs had significantly poorer outcomes. MRI) should be used if there is a high index of suspicion for LCPD. The z-score for height, AA, CEA, femoral head coverage, and number of surgical proce-dures were compared by the Mann-Whitney test. The diagnosis requires a careful history, physical examination, and x-rays. The Stulberg classification was used to examine the sphericity of the hip joint. The resulting classification consists of four groups: A, B, B/C border, and C. In our application of the classification system of Stulberg et al., we defined a class-II femoral head as round and. With the Perthes hip, the amount of recontouring that is able to be conducted will depend upon preoperative templating and how ovoid the femoral head-neck junction is. The statistical analysis of the significance of differences was performed using the student test and Fisher exact test. The reflected tendon of the rectus femoris is divided from the direct portion and dissected posteriorly. Anatomical proximal femoral angle was used to evaluate functional coxa vara (Fig. Recontouring of the femoral head-neck junction will depend on the Stulberg classification, with Stulberg I/II hips more amenable to a suitable osteochondroplasty (Fig. The factors that affect leg length discrepancy may be more complex. article, or locate the article citation on jbjs.org and click on the [Reprints and The Salter-Thompson classification of Perthes disease simplifies the Catterall classification into two groups. The only difference in methodology from the series in south-west India was the addition of assigning the modified Stulberg classification . Herring JA, Kim HT, Browne R. Legg-Calve Perthes disease. Therefore, all possible prognostic factors are assessed during childhood on their in- fluence on femoral head shape and hip congruence at the end of the growth, which is usually classed according. The resulting classification consists of four groups: A, B, B/C border, and C. In our application of the classification system of Stulberg et al., we defined a class-II femoral head as round and fitting within 2 mm of a circle on both anteroposterior and frog-leg lateral radiographs. However, the variability of the disease and long term follow up needed to understand the outcome of treatment have contributed . As part of a prospective multicenter study, we sought to define more clearly the lateral pillar classification of severity and the Stulberg classification of outcome; we sought especially to define the borderlines between . STULBERG CLASSIFICATION • Described in 1981 • Alike MOSE, classification of THE END RESULTS • Used to predict the onset of degenerative joint disease following LCPD • Based on size and shape of femoral head Dr.Anoop G.C.,JR,Orthopaedics,GMCK The Stulberg classification was used for final results of radiological assessment . The Stulberg classification also predicts progression to OA with the incidence of OA higher in the more advance grades. The modified lateral pillar classification and the redefined Stulberg classification are sufficiently reliable and accurate for use in studies of Legg-Calv{\'e}-Perthes disease.", Class V hip showing 'aspherical in-congruency . As part of a prospective multicenter study, we sought to define more clearly the lateral pillar classification of severity and the Stulberg classification of outcome; we sought especially to define the borderlines between . Since these symptoms and signs are not specific to the disease, x-rays are required to . The modified lateral pillar classification and the redefined Stulberg classification are sufficiently reliable and accurate for use in studies of Legg-Calve-Perthes disease and produced kappa values and generalizability coefficients in the excellent range.
