Study finds, Association of developmental lumbar spinal cana
A Study was conducted to determine a possible relationship between developmental lumbar spinal canal stenosis (DLSS) and stunting.

Stunting is due to failure of longitudinal length with shortened long bones. Stunted individuals have failure of growth of long bones implying a possibility of involvement of short and flat bones. The hypothesis in this study is that DLSS is part of a generalized skeletal dysplasia.

This is a cross-sectional study (CSA) of 400 patients looking at the association of DLSS with stunting. The study compares the size of the spinal canal in individuals with stunting and those without stunting. Stunting was defined according to the WHO/UNICEF criteria of 2SD of the median height of the same population.

The participants were divided into two types: those who were deemed stunted and those who were not. DLSS was similarly defined as 2SD of the relevant measured parameter. The study included skeletally mature patients between 18 and 60 years. All syndromic individuals, those with spine tumors and previous spine surgery, were excluded.

Results:
--400 individuals were sampled from a pool of 597 participants. 108 or 27% were stunted.

--The stunted individuals had statistically significantly shallow canal depths or anteroposterior diameters (11.2 ± 2.0mm vs. 14.6 ± 2.6mm), and narrower canal widths (transverse diameters) (14.6 ± 3.3mm vs. 18.8 ± 4.5mm) and smaller CSAs (134.0 ± 49.4mm vs. 220.2 ± 82.0) when compared to individuals with normal heights.

Finally, when compared to non-stunted individuals, stunted individuals have smaller lumbar spinal canals. Developmental lumbar spinal canal stenosis may be determined to be part of widespread skeletal dysplasia.
