摘　　要：Aim: To determine the normal carpal height ratio for the Trinidadian population. Design & method: A retrospective review of wrist radiographs performed during the period January 2022 to June 2022 at San Fernando General Hospital was conducted. A total of 200 radiographs were independently reviewed by two blinded assessors utilizing the PACS system. The carpal height ratio (CHR) and revised carpal height (RCH) ratio was calculated using two methods. A p-value Results: The radiographs reviewed consisted of 94 female and 106 male patients with an age range of 19 to 86 years. The mean CHR was 0.473 and the revised CHR 1.469. The ratio for carpal height as well as the revised CHR was observed to vary amongst the different age groups studied. The CHR and revised CHR for the population was observed to vary based on gender with gender significantly influencing the CHR value (p = 0.001). Conclusions: The CHR of the Trinidadian population as calculated by the data collected falls below the average CHR documented worldwide. However, the interpretation of this value is based on the baseline reference ratio for a population. Therefore, according to our average CHR for our population previous comparison of a CHR index to international figures would have led to erroneous interpretation of results. A decrease in CHR is indicative of carpal collapse. The comparison of CHR to the established normal CHR for the population is believed to allow for early detection of carpal collapse.Aim: To determine the normal carpal height ratio for the Trinidadian population.
