“…Lappin et al [11] reported that 92 (33%) of 275 patients who were managed conservatively in several hospitals showed changes in their LP grades during their treatment periods [12]. Our result was consistent with the results reported by Lappin et al [11].…”

“…This classification has thus been widely used in clinical practice, but it usually assesses patients at the fragmentation stage of disease, rather than at the initial examination. In addition, Lappin et al [11] reported that the LP classification grade might change during the course of treatment. Therefore, an evaluation of the initial radiographic findings according to the LP classification may not correlate with those of the final outcomes.…”

The purpose of this study was to examine the correlation between the changes in the lateral pillar grades and the factors influencing such changes. We reviewed 102 patients with Perthes' disease. Changes were observed in 32 (31%) hips. The percentage of the changes in each treatment group showed significant differences. Patients with extensive involvement showed significantly more changes. There was no difference in the age at the onset. We recommend that treatment methods be used that more effectively relieve the mechanical force on the capital femoral epiphysis for patients with extensive involvement regardless of the age at the onset.

“…The Herring classification has been widely accepted because of its simplicity and reproducibility. However, Lappin et al [9] have suggested that the Herring grade changes with time, especially in the early stages of the disease. We therefore decided to classify our patient's with both the Catterall and the Herring classifications.…”

“…The lateral pillar and the Catterall classification systems can only be applied after significant femoral head deformity occurs. [4][5][6][7] Ideally, a prognosticator that can be applied before this occurs would be optimal in guiding treatment decisions. The extent of subchondral fracture in the early stage of fragmentation has also been assessed for its prognostic value.…”

“…Early application of these classifications has been shown to lead to incorrect assignment and prognostication in some patients. 6,7 Clearly, there is a need to develop a prognosticator that can be applied at early stages of LCPD before development of significant deformity.…”
