Evaluation of Tibial Slope on Radiographs in Pediatric Patients With Tibial Spine Fractures: An Age- and Sex-Matched Study

BACKGROUND: A recent study has reported that the radiographic measurement of posterior tibial slope (PTS) is larger in male pediatric patients with tibial spine fractures (TSF) than in controls. However, they found no difference in PTS between female patients and controls. PURPOSE: (1) To identify whether PTS is larger in female pediatric patients with TSF than in female controls and (2) to validate the relationship between PTS and pediatric TSF in male patients. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: After an a priori power analysis, 84 pediatric patients with TSF (50 female patients and 34 male patients) and 84 age- and sex-matched controls were enrolled in this study. Demographic information, including sex, age, and race, was recorded. Skeletal maturity was determined based on the stage of epiphyseal union on knee radiographs. PTS was defined as the angle between a line perpendicular to the longitudinal axis of the tibia and the posterior inclination of the medial tibial plateau on standard knee lateral radiographs. RESULTS: The mean age when the TSF occurred was 11.2 ± 2.7 years for female patients and 12.9 ± 2.5 years for male patients. There was no significant difference in skeletal maturity between female patients and female controls or between male patients and male controls. The mean PTS was not significantly different between female patients (8.8°± 2.8°) and female controls (8.3°± 3.1°) ( CONCLUSION: PTS was not found to be a risk factor for pediatric TSF in female or male patients in this study

Persistency in crested dogstail : its relation to origin, flowering date, seed colour and germination capacity of New Zealand seed samples : thesis for M. Agr. Sc., by "Asteroid" [F. Sydenham]

"Asteroid" is the nom de plume of F. SydenhamCrested dogstail is a valuable pasture grass, and is sown under a wide range of soil conditions. It is essentially a bottom grass. It is very palatable to sheep and thrives well under conditions of continous close grazing. It does not, however, feature to any large extent in dairying land. It shows very great powers of re-establishment by seeding even under adverse seed-bed conditions, and it is this re-establishment which enables it to persist in a pasture for a number of years. Such re-establishment should not occur each Autumn after the plants have seeded and died or are so low in vitality that they remain only as worthless vestiges. This is a weakness of crested dogstail which it is desirable to eliminate. What it requires is a vigorous turf which will, on the advent of Autumn rains, spring into a highly productive sward vigorous enough to check any inferior grasses or weeds which may attempt to gain a footing.
