Introduction

Despite all modern advances the indications and possibilities of treatment in Legg-Calvé-Perthes Disease (LCPD) are still controversial. In the past 15 years we started using arthrodiastasis of the hip creating negative pressure over the avascular femoral head in some selected cases of LCPD in the active phasis of the disease. Now we present our experience with distraction in LCPD using the original Ilizarov circular frame for the hip.

Materials and Methods

From 2015 to 2021, eight patients with LCPD were submoitted to hip distraction; all male ranging from six to 12 years (avg 8.2 years). All patients with bad prognosis, in Catterall Groups III and IV. All patients in the active phasis of the disease. Our follow-up is ranging from two to six years, with an average of 3.4 years.

Aims

This pilot study aimed to evaluate prospectively the use of inlet radiographs of the hip as an alternative method of the assessment of reduction after the surgical treatment of developmental dysplasia of the hip (DDH).

Patients and Methods

The children in this study underwent surgery between January 2013 and January 2015. All had inlet radiographs and CT scans post-operatively. Data were analysed by determining inter-observer reliability and intra-observer reproducibility, using the kappa value (K). Differences were settled by discussion between the two observers until a consensus was reached. The sensitivity and specificity of the radiographic and CT results were compared. A total of 26 radiographs were obtained from 23 children, with a mean age of 2.38 years (one to five).
