This is the main radiologic prognostic factor of final Stulberg grading (11). It is also a prognostic factor of length discrepancy of the lower limbs. sphericity of femoral head and congruency at skeletal maturity (Stulberg classification) Classification - Lateral Pillar has best agreement, and most predictive.

Indications for invasive treatment depend mostly on prognosis, which can be assessed during childhood or adulthood.

Legg-Calvé-Perthes disease: classifications and prognostic factors

Methods Computerized bibliographic search in PubMed was performed stulberg classification keywords as follows: On studies, we selected 21 for systematic review. We manually added 12 historical major articles.

  • Legg-Calve-Perthes Disease (Coxa plana) - Pediatrics - Orthobullets
  • Stulberg classification system.
  • Legg-Calve-Perthes Disease (Coxa plana)
  • Stulberg classification system.

Main criteria of judgment The overall prognosis depends on hip congruence at stulberg classification end of stulberg classification, which directly influences degenerative changes and osteoarthritis in adulthood 1. J Bone Joint Surg Am. Researchers and clinicians commonly use the classification system of Stulberg et al.


It is generally assumed that this system has an acceptable degree of reliability. They stulberg classification that each class was associated with a predictable clinical and radiographic course.

Inter-observer reliability of the Stulberg classification in the assessment of Perthes disease

Although the classification of Stulberg is widely used, only a few studies have evaluated the inter-observer stulberg classification of this system. In the present study, the inter-observer reliability of the Stulberg classification system with the use of the consensus algorithm by Neyt et al.

The aim was to stulberg classification whether the Stulberg classification is sufficiently reliable for routine clinical use in the assessment of Perthes disease. Patients and methods During the 5-year period —, a nationwide prospective study on Perthes disease, initiated by the Norwegian Paediatric Orthopaedic Society, was carried out.

We evaluated the radiographs of hips in 90 patients 11 had bilateral affection. The radiographs were assessed by an orthopaedic surgeon with great experience in examining the radiographs of children SSan experienced paediatric orthopaedic surgeon TT and an orthopaedic surgeon in the training of paediatric stulberg classification practice OW.

We used the Stulberg classification as modified by the algorithm of Neyt et al. Class I hips are stulberg classification with normal femoral head, neck and acetabulum.

Class II hips have spherical femoral head with either coxa magna, short neck or steep acetabulum.
