Reliability study for rib index
نویسندگان
چکیده
Objectives The Rib Index, (RI), extracted from the double rib couture sign (DRCS) on lateral spinal radiographs to evaluate rib hump deformity in IS patients has been earlier introduced (Grivas at al 2000). Although various papers using the RI have been published, no study of its reproducibility was reported. To estimate the variations of the RI in a number of a pair set of lateral chest radiographs of healthy volunteers. The hypothesis was that the RI should have minimal variability for each patient having successive lateral radiographs.

متن کاملA Rare Preterm Newborn Case of Rib Osteomyelitis with Intrathoracic Involvement
Background: Rib osteomyelitis is a very rare form of pediatric osteomyelitis. Case report: Herein, we reported a very rare case of chest wall abscess with rib osteomyelitis and rib destruction due to Staphylococcus aureus infection in a 14-day-old preterm male neonate. The diagnosis of this uncommon disease requires a high index of suspicion due to its rarity and non-specific clinical presenta...
متن کاملOptoelectronic plethysmography: Intra-rater and inter-rater reliability in healthy subjects
Optoelectronic plethysmography (OEP) has been used to measure changes in chest wall volume and its compartments. However, literature lacks research on its reliability. The purpose of this study was to evaluate the intra-rater and inter-rater reliability of OEP. Thirty-two healthy subjects were evaluated at rest and during submaximal exercise on a cycle ergometer. The following variables were as...
متن کاملFatigue Reliability Assessment for Orthotropic Steel Decks Based on Long-Term Strain Monitoring
A time-dependent fatigue reliability assessment approach is proposed for welded details of orthotropic steel decks (OSDs) using long-term strain monitoring data. The fatigue reliability limit function of the welded details is established based on the Eurocode specifications. Depending on the distribution characteristics of the measured daily equivalent stress range, either the lognormal distrib...
متن کاملThe rib index is not practically affected by the distance between the radiation source and the examined child
BACKGROUND All lateral spinal radiographs in idiopathic scoliosis (IS) show a Double Rib Contour Sign (DRCS) of the thoracic cage, a radiographic expression of the rib hump. The outline of the convex overlies the contour of the concave ribs. The rib index (RI) method was extracted from the DRCS to evaluate rib hump deformity in IS patients. The RI was calculated by the ratio of spine distances ...
