Background: Ventilation with low tidal volume (VT) is advised for critically ill patients to protect against ventilator-induced lung injury and provide better clinical outcomes. Previous studies showed poor compliance with using height to predict the VT. Ulna length has been used successfully to predict protective low VT. Our study aims to evaluate the ability of ulna length measurement to predict accurate protective lung VT in Egyptian people in reference to their standing height. Methods: we included adult healthy volunteers with age ≥ 18 years in this study. The height of each subject was measured while standing upright against a wall. Then, the left ulna was measured with a measuring tape from the olecranon to the mid-point of the styloid process. From ulna length, height was estimated, and protective lung VT was calculated using predicted body weight (PBW). Results: We enrolled 102 participants in this study. The agreement between the calculated VT from standing height and ulna length was analyzed with Bland Altman analysis and showed a bias of (-5.7) ml, and limits of agreements (±1.96 SD) -91 ml to 76 ml. in females, When the calculated VT of ulna length was compared to PBW from height, the predicted mean tidal volume was 6.2 ml/kg (95% confidence interval CI 4.5-7.8 ml/kg). in males, by using ulna length, the predicted mean VT was 6.1 ml/kg (95% CI 4.8-7.4 ml/kg). Conclusion: Ulna length can be used to predict protective lung VT in Egyptian people when compared to their standing height.Trial registration: NCT04644458 ClinicalTrials.gov 09/26/2021

“…The current finding of high correlation when using ulna length as a surrogate height measure is consistent with other international studies. These studies have analysed a wide age range and in a variety of populations: infants, 7 adolescents, 3,[23][24][25][26] adults 20,22 and older adults. 16 All of these populations found a linear relationship between height and ulna length.…”

“…7,15,16 Furthermore, it has greater precision than the lower limbs in formulating a regression equation. 18 Ulna length has also been shown to have high reliability and correlation with height in several adult studies, 15,[19][20][21][22] although only a few studies have assessed this in adolescents. 3,[23][24][25][26] From these, only four studies provided equations from which to estimate height.…”

Background The measurement of height is crucial for weight status assessment. When standing height is difficult to measure, ulna length may offer a convenient and accurate surrogate of height measure. Adolescence is a period of accelerated linear growth; hence, the validation of age‐specific equations that predict height from ulna length in adolescents is warranted. The present study aimed to develop and validate age‐ and sex‐specific equations for predicting height from ulna length in New Zealand adolescents. Methods Height, weight and ulna length were measured in 364 adolescents (n = 110 males, n = 254 females) aged 15.0–18.8 years, who were enrolled in the SuNDiAL (Survey of Nutrition Dietary Assessment and Lifestyle) project, a cross‐sectional survey performed in 2019 and 2020. Regression models were used to determine equations to predict height from ulna length. Agreement between measured and predicted height, body mass index (BMI) and BMI z‐score was assessed with intra‐class correlation coefficients (ICC) and Bland–Altman plots. Sensitivity and specificity were calculated for classifying obesity. Results Strong agreement was found between predicted and measured height (ICC = 0.78; mean difference = 0; 95% confidence interval = −0.5 to 0.5 cm) and BMI (ICC = 0.95; mean difference = 0; 95% confidence interval = −0.1 to 0.1 kg m–2). Predicted height was 88.1% accurate when classifiying weight status, showing high sensitivity (93.8%) and specificity (99.4%) for classifying obesity. Conclusions Ulna length measurement can accurately estimate height and subsequently weight status in New Zealand adolescents aged 15–18 years.

“…Patient’s height showed a weaker correlation with CC field length and this could be explained by a change in patient height not being in proportion to a change in the patient’s neck length. Other clinically measurable anthropometric factors such as the percutaneous lengths of the ulna 13 and tibia 14 have been reported to be predictors of a patient’s stature. However, these measurements were not readily available for correlation with the CC field length and this analysis was beyond the scope of this study.…”

Objective: This study investigates the impact of a restricted craniocaudal (CC) field length of <20 cm on the selection of head and neck cancer (HNC) patients who can be treated on the MR-Linac using a single isocentre technique. We also assess the effects of anthropometric factors and the neck position on the CC field length. Methods: 110 HNC patients who underwent radical primary or adjuvant radiotherapy were retrospectively analysed. We assessed the proportion of treatment fields with a CC length of <20 cm and the effects of gender, height, hyo-sternal neck length (distance from superior surface of hyoid to sternal notch measured on the coronal reconstruction of the planning CT) and neck position on CC length. Results: 95% of HNC patients had a CC field length <20 cm. Female patients showed a significantly shorter median CC length than male patients in both extended (p = 0.0003) and neutral (p = 0.008) neck positions. Neck position influenced the median CC length with neutral neck being significantly shorter than extended neck (p = 0.0119). Patient height and hyo-sternal neck length showed positive correlation with the CC length, with neck length in neutral position having the strongest correlation (r = 0.65, p = 0.0001 and r = 0.63, p < 0.0001, respectively for extended neck; r = 0.55, p = 0.0070 and r = 0.80, p < 0.0001, respectively for neutral neck). A hyo-sternal neck length of <14.6 cm predicted a CC length of <20 cm in neutral neck position. Conclusion: The majority of patients with HNC at the Royal Marsden Hospital have anthropometric features compatible with their being treated on the MR-Linac using a single isocentre technique. The absolute CC field size may vary according to primary tumour site, patient factors and neck position. A hyo-sternal neck length cut-off of 14.6 cm in the neutral neck position can be used as a surrogate marker for suitability of treatment on MR-Linac. Advances in knowledge: This paper highlights the potential impact of a restricted CC field in HNC patient selection for the MR-Linac treatment. This is the first report to suggest the use of neck length as a surrogate marker for suitability of treatment on the MR-Linac.
