curve flexibility in adolescent idiopathic scoliosis (ais) was one of the major concerns of spinal surgeons since the evolution of surgical correction techniques. in this respect, many tried to identify which criteria denote more rigid curve. in the present study, we aimed toward determining important factors influencing ais curve flexibility on supine bending films. we assessed radiographs of ...

UNLABELLED Pronation might favorably affect respiratory system (rs) mechanics and function in volume-controlled, mode-ventilated chronic obstructive pulmonary disease (COPD) patients. We studied 10 COPD patients, initially positioned supine (baseline supine [supine(BAS)]) and then randomly and consecutively changed to protocol supine (supine(PROT)), semirecumbent, and prone positions. Rs mechan...

BACKGROUND Gastro-oesophageal reflux disease (GORD) plays a major role in the development of Barrett's oesophagus. However, it has yet to be elucidated what factors determine the length of Barrett's mucosa in each individual patient. AIMS To determine if there is a correlation between oesophageal acid exposure and the length of Barrett's mucosa. We also compared the extent of oesophageal acid...

Colonography is an important screening tool for colorectal lesions. This paper presents a method for establishing spatial correspondence between prone and supine inner colon surfaces reconstructed from CT colonography. The method is able to account for the large deformations and torsions of the colon occurring through movement between the two positions. Therefore, we parameterised the two surfa...

After cardiac catheterisation, haemostasis is usually achieved by manual compression of the puncture site. The patient is then laid flat, allowed to sit up and then to mobilise—a process taking considerably longer than the procedure itself, and possibly involving more prolonged bed occupancy than is necessary. Well conducted, randomised, controlled trials of patient position (supine or upright)...

When anterior reduction fail in the surgical treatment of cervical bilateral facet fracture-dislocation with concomitant disc extrusion, it is necessary to perform a reduction using a posterior approach and then a third anterior procedure is often necessary to accomplish the anterior reconstruction. This presents difficulties for both patients and surgeons because of the need for frequent posit...

Abstract Introduction Obstructive sleep apnea (OSA) is well known to often improve with non-supine positioning as opposed supine positioning. The prevalence of OSA that may on proper 50-60% and the appears when disappears 25-30%. Sleeping in a lateral thought reduce pressure airway, shift directional effect gravity airway structures, counteract physiologic genioglossus collapse occurs supine. O...

background nowadays percutaneous nephrolithotomy (pcnl) is performed in prone and supine positions. physiologic solutions should be used to irrigate during pcnl. irrigation can cause hemodynamic, electrolyte and acid-base changes during pcnl. objectives the current study aimed to compare the electrolyte, hemodynamic and metabolic changes of prone and complete supine pcnl. patients and methods i...
