Ultrasound-guided distal minimally invasive metatarsal osteotomies (US-DMMO): A cadaveric study about its safety and accuracy.

Background: Distal minimally invasive metatarsal osteotomies have become increasingly popular. This technique requires fluoroscopic control, but recently, an ultrasound-guided procedure has been described. The aim of this anatomical study was to assess the quality safety of ultrasound-guided minimally invasive metatarsal osteotomies.

Preoperative and postoperative sagittal plane analysis in adult idiopathic scoliosis in patients older than 40 years of age.

Background Context: Most of the papers correlate sagittal radiographic parameters with health-related quality of life (HRQOL) scores for patients with scoliosis. However, we do not know how changes in sagittal profile influence clinical outcomes after surgery in adult population operated for mainly frontal deformity.

Purpose: This study aimed to analyze spinal sagittal profile in a population operated on adult idiopathic scoliosis (AS) and to describe variations in sagittal parameters after surgery and the association between those variations and clinical outcomes.
