To evaluate the usefulness of the modified lateral pillar classification as a prognostic factor in Legg-Calvé-Perthes disease (LCPD).
Thirty nine patients diagnosed with lateral pillar C in LCPD from May, 1977, to October, 2001 were reviewed, and their skeletal maturity was followed. The mean follow up duration was 12 years and 7 months (4 years, 6 months to 24 years, 9 months). Lateral pillar C classification was divided into C1 (50-75% collapse of the lateral pillar) and C2 (> 75%). All radiological and clinical prognostic factors were evaluated. The final results were evaluated according to the Stulberg classification.
Twenty one and 18 of the affected hips were in groups C1 and C2, respectively. According to the Stulberg classification, the final results of group C1 were better than those of C2 (p = 0.002). Patients with more head-at-risk signs had significantly poorer outcomes.
The modified lateral pillar classification has significant value for predicting the prognosis of LCPD.
评估改良的外侧柱分型作为 Legg-Calvé-Perthes 病(LCPD)的预后因素的有用性。
回顾 1977 年 5 月至 2001 年 10 月期间诊断为 LCPD 外侧柱 C 型的 39 例患者,并对其骨骼成熟度进行随访。平均随访时间为 12 年 7 个月(4 年 6 个月至 24 年 9 个月)。外侧柱 C 型分为 C1(外侧柱塌陷 50-75%)和 C2(>75%)。评估了所有影像学和临床预后因素。最终结果根据 Stulberg 分类进行评估。
受累髋关节中,C1 组和 C2 组分别为 21 例和 18 例。根据 Stulberg 分类,C1 组的最终结果优于 C2 组(p=0.002)。头骺受累征象较多的患者预后明显较差。
改良的外侧柱分型对预测 LCPD 的预后具有重要价值。
