A three dimensional triangular space ‘the Kambin’s triangle (KT)’ present on the dorsolateral aspect of the intervertebral disc, is considered to be a safe area for transforaminal approaches. It allows access to the exiting and traversing nerve roots, the thecal sac and to the intervertebral disc spaces. Our aim was to calculate the area of the triangle by measuring the height and base at all the intervertebral spaces bilaterally in the lumbar region in North West Indian cadavers and to assess the diameter of circle inscribed within this triangle which will correspond to the size of cannula inserted for the minimally invasive transforaminal approaches in this population. Five randomly chosen adult cadavers were used for this study. After clearing the area, the exiting nerve was identified. The height and base of the bony KTs (n=40) were measured with the help of digital Vernier’s calliper (accuracy 0.02 mm) to calculate the area of the KT. There is a steady increase in the area of the bony KT reaching maximum at the level of L4-5 intervertebral space. Statistically there were no differences in the calculated areas between right and left side. The mean diameter of inscribed circle within the triangle also showed gradual increase from 5.82 mm at L1-2 level, reaching maximum value of 7.26 mm at L4-5 level on the right side while on the left side the values were 5.66 mm and 8.16 mm respectively. Careful anatomical consideration is of utmost importance in transforaminal approaches during surgical or interventional procedures in this region. Cannula having external diameter ranging 6–8 mm is recommended for any interventional approach through Kambin’s space.

Introduction: Ageing is a natural and irreversible process, associated with deterioration of physiological, social and cognitive activities. The nutritional status of the elderly is adversely affected by declining cognitive and functional ability. The association of nutritional status with diet quality, functional and cognitive ability and depression among the elderly is not well understood. This study aimed to compute the association of nutritional status with diet quality, functional and cognitive ability and depression among the elderly. Method: A cross-sectional study was undertaken on 250 elderly (146 men, 104 women) of ≥65 years, residing in Tonk district of Rajasthan (India). Self-developed elderly dietary index (EDI) was used to evaluate diet quality and standardized tools, viz., geriatric depression scale (GDS), activities of daily living (ADL), instrumental activities of daily living (IADL), mini nutritional assessment (MNA), and short portable mental status questionnaire (SPMSQ) were used to assess depression, functional status, nutritional status and cognition respectively. Results: Two-thirds of the elderly in this study were at risk of malnutrition (66.67%, n= 167). MNA scores had significant association with Indian EDI (χ2 = 47.50, p=0.000), ADL (χ2 = 32.37, p= 0.000) and SPMSQ (χ2 =18.61, p= 0.001), whereas MNA scores had non significant association with IADL (χ2 = 14.30, p= 0.006) and GDS scores (χ2 = 5.44, p= 0.066). IADL scores were found to be significantly correlated with GDS (r= -0.255) and SPMSQ (r= -0238) Conclusion: Present study shows that the nutritional status of the elderly is associated with diet quality, functional and cognitive ability, but is not associated with depression in the elderly of Tonk.
