We compared the accuracy of the growth remaining
method of assessing leg-length discrepancy (LLD) with the straight-line
graph method, the multiplier method and their variants. We retrospectively
reviewed the records of 44 patients treated by percutaneous epiphysiodesis
for LLD. All were followed up until maturity. We used the modified Green–Anderson
growth-remaining method (Method 1) to plan the timing of epiphysiodesis.
Then we presumed that the other four methods described below were
used pre-operatively for calculating the timing of epiphysiodesis. We
then assumed that these four methods were used pre-operatively.
Method 2 was the original Green–Anderson growth-remaining method;
Method 3, Paley’s multiplier method using bone age; Method 4, Paley’s
multiplier method using chronological age; and Method 5, Moseley’s
straight-line graph method. We compared ‘Expected LLD at maturity
with surgery’ with ‘Final LLD at maturity with surgery’ for each
method. Statistical analysis revealed that ‘Expected LLD at maturity
with surgery’ was significantly different from ‘Final LLD at maturity
with surgery’. Method 2 was the most accurate. There was a significant
correlation between ‘Expected LLD at maturity with surgery’ and
‘Final LLD at maturity with surgery’, the greatest correlation being
with Method 2. Generally all the methods generated an overcorrected
value. No method generates the precise ‘Expected LLD at maturity
with surgery’. It is essential that an analysis of the pattern of
growth is taken into account when predicting final LLD. As many
additional data as possible are required. Cite this article:
Slipped capital femoral epiphysis (SCFE) is uncommon
in India and we routinely look for associated metabolic or endocrine
abnormalities. In this study we investigated a possible association
between vitamin D deficiency and SCFE. All children presenting with
SCFE during the study period had their 25-hydroxyvitamin D levels
measured as part of an overall metabolic, renal and endocrine status
evaluation, which included measurement of body mass index (BMI).
Vitamin D status was compared with age-, gender- and habitat-matched
controls with acute trauma or sepsis presenting to our emergency
department. A total of 15 children (12 boys and three girls) with a mean
age of 13 years ( Cite this article:
It has been reported that there is an association between Perthes’ disease and poverty. We examined the demographic data of a group of 240 children (263 hips) who presented with Perthes’ disease in Greater Glasgow, where the mean deprivation scores are substantially greater than in the rest of Scotland, to see if this association applied and whether other clues to the aetiology of Perthes’ disease could be found. There were 197 boys and 43 girls; 39 (16.25%) had a family history of Perthes’ disease. Bone age in this series was heavily skewed towards the lower percentiles. The mean number of siblings was 1.9, with 31 (12.9%) being an only child. Maternal age at the birth of the first child showed no preponderance of older mothers. Maternal smoking during and after pregnancy was noted in 132 (55%), which compared with the 52% reported in the population of Greater Glasgow in general. Of the children in our series, 60 (25%) were in social class IV and V. However, this applies to more than half of the population of Greater Glasgow. There was no significant evidence of a preponderance of Perthes’ disease in the most deprived groups. The aetiology of Perthes’ disease is likely to be multifactorial and may include a genetic or deprivation influence resulting in delayed bone age.
