Comparison of PACS and Hard-copy 51-inch Radiographs for Measuring Leg Length and Deformity

Abstract

Level III, diagnostic study. See the Guidelines for Authors for a complete description of levels of evidence.

Femoral Lengthening with Lengthening over a Nail has Fewer Complications than Intramedullary Skeletal Kinetic Distraction

“…This is commensurate with published studies showing satisfactory lengthening using the ISKD [3,5,10,23] and LON [2,12,18], respectively.…”

“…In the ISKD group 50% of patients had A quality and 17% had C quality at 8 weeks. Not all studies use a standardized method of assessing the quality of bone regenerate during distraction; however, some have described the risk of development of poor regenerate bone [7,8,11,12,18,22,24] with a lengthening rate faster than 1 mm per day. Kenawey et al [10] proposed other risk factors associated with poor bone regenerate from their analysis of 37 femoral ISKD lengthenings for which insufficient bone regenerate developed in eight patients (23%).…”

Brain MRI Measurements at a Term-Equivalent Age and Their Relationship to Neurodevelopmental Outcomes

“…We used the PACS system of the Asan Medical Center, which has been described in detail in Im et al 21 to measure the different brain parameters. Other reports [29][30][31] have shown the usefulness of this system, emphasizing its reproducibility and reliability as well as the convenient access to images. Unlike the other 9 MR imaging parameters that we also measured (data not shown), which included ventricle width, biparietal diameter, bifrontal diameter, subarachnoid space widening (axial and sagittal images), and corpus callosal thickness.…”

Whatʼs New in Pediatric Orthopaedics

“…In the study by Moore et al, the injection of recombinant human platelet-derived growth factor-BB in a rat model of diaphyseal distraction suggested a significantly increased healing rate and enhancement of bone formation 38 Khakharia et al evaluated the transition from traditional long-leg radiographs to digital imaging for the evaluation of angular deformity by comparing standard measurements on the PACS (picture archiving and communication system) with standard fifty-one-inch radiographs. Both techniques showed excellent intraobserver and interobserver reliability 41 . Sabharwal et al, in an investigation into the hip-knee-ankle angle and femoral-tibial axis measurement on the long-leg radiographs of 354 limbs of children ranging from one to eighteen years of age, reported approximation of adult values by seven years of age 42 .…”
