Key result
The lateral pillar classification grade changed during treatment in 31% of patients with Perthes' disease, with mechanical loading on the lateral epiphysis and extensive necrosis significantly increasing the likelihood of grade change.
Why the study?
Do different conservative treatment methods affect the changes in lateral pillar classification grades in patients with Perthes' disease?
Observational (n=102)
Do different conservative treatment methods affect the changes in lateral pillar classification grades in patients with Perthes' disease?
In Perthes' disease, lateral pillar classification grades can worsen during treatment, particularly in patients with extensive involvement or those receiving partial weight-bearing treatments, suggesting a need for therapies that effectively relieve mechanical force in severe cases.

May signal need for stricter unloading in extensive Perthes necrosis; leaves open whether specific conservative methods alter grade stability.
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.

Kuroda et al. (2009) conducted an observational in Perthes' disease (n=102). Conservative treatment (mechanical loading vs non-weight bearing) vs. Non-weight bearing conservative treatment was evaluated on Change in lateral pillar (LP) classification grade during treatment. The lateral pillar classification grade changed during treatment in 31% of patients with Perthes' disease, with mechanical loading on the lateral epiphysis and extensive necrosis significantly increasing the likelihood of grade change.
