Radiographic outcome after greater trochanteric epiphysiodesis in patients with Perthes disease.

Purpose: Legg-Calvé-Perthes disease often leads to greater trochanteric overgrowth, which negatively affects the biomechanics of the hip joint. This study aimed to evaluate the physiologic growth of the greater trochanter and the effectiveness of greater trochanteric epiphysiodesis radiographically.

Methods: Retrospectively, 46 children (33 male, average age at greater trochanteric epiphysiodesis 8 ± 1.

Midterm Development of Ultrasound-unstable Hip Joints After Overhead Traction and Treatment With Tübingen Splint and Fettweis Plaster: A Radiologic Follow-up Analysis Over 5.5 Years.

Purpose: The aim of this study was to determine the success rate for treatment of ultrasound unstable hips (type D, III and IV) with Fettweis plaster in terms of a midterm follow-up from the very beginning in the neonatal period until the age of 4 to 8 years.

Methods: In total, 69 unstable hips, which were successfully treated with Fettweis plaster and after with a flexion-abduction splint, were included into the study. Hip delvelopment was followed by determining the acetabular index (ACI) on routine pelvic radiographs at the age of 12 to ≤24, 24 to ≤48 and 48 to ≤96 months and the center edge angle on the latter, and classifying both angles according to Tönnis.

Radiological long-term follow-up up to 12 years of initially ultrasound unstable hip types D, III and IV after treatment with the Tübingen splint worn as a plaster.

Introduction: The treatment of ultrasound unstable hips with the Tübingen splint is currently under discussion. However, there is a lack of long-term follow-up data. This study presents to the best of our knowledge first radiological mid-term to long-term data of the successful initial treatment with the Tübingen splint of ultrasound unstable hips.

[Juvenile osteochondrosis and osteonecrosis].

Background: Juvenile osteonecrosis is an important topic in orthopedics. A wide variety of body regions of the growing patient are affected, predominantly during adolescence. All are characterized by a usually unknown aetiology as well as a stadium-like course.
