Article Synopsis
- The text discusses the risks of avascular necrosis (AVN) in patients with unstable slipped capital femoral epiphysis (SCFE) treated with the modified Dunn procedure, highlighting uncertainties around the classification of instability and its correlation with surgical outcomes.
- The study aimed to assess the long-term effectiveness of the modified Dunn procedure by measuring the survivorship free from AVN, the need for additional surgeries, and the overall clinical outcomes after 10 years.
- A total of 159 patients were analyzed, with 58 showing intraoperatively observed epiphyseal-metaphyseal discontinuity, and outcomes were evaluated for a significant majority of these patients, providing important data for future treatment approaches.

Femoroacetabular impingement (FAI) patients with reduced femoral version (FV) are poorly understood. The aim of this study is to assess (i) hip pain and range of motion, (ii) subjective satisfaction and (iii) subsequent surgeries of symptomatic patients who underwent rotational femoral osteotomies. A retrospective case series involving 18 patients (23 hips, 2014-2018) with anterior hip pain that underwent rotational femoral osteotomies for treatment of decreased FV was performed.

- Abnormal femoral head shape from slipped capital femoral epiphysis (SCFE) can lead to hip problems like femoroacetabular impingement and early osteoarthritis, making surgical correction important to restore hip anatomy.
- The modified Dunn procedure offers a surgical approach that aims to correct the anatomy of the hip without damaging the blood supply to the femoral head, reducing the risk of osteonecrosis.
- The procedure involves a careful dislocation of the hip and meticulous shaping of bones while maintaining blood vessel integrity, allowing for effective repositioning and fixation of the femoral head.
Introduction: In situ pinning is an accepted treatment for stable slipped capital femoral epiphysis. However, residual deformity of severe slipped capital femoral epiphysis can cause femoroacetabular impingement and forced external rotation.
Purpose/questions: The aim of this study was to evaluate the (1) hip external rotation and internal rotation in flexion, (2) hip impingement location, and (3) impingement frequency in early flexion in severe slipped capital femoral epiphysis patients after in situ pinning using three-dimensional computed tomography.
