Abstract

Background: Analyzing the relationship among forearm along with little finger length plus femoral length may reveal hidden connections in skeletal proportions, shedding light on human anatomy and biomechanics. Objective: To check the association among the combined measurements of the forearm and little finger and the actual measurement of the femur. Study Design: Cross sectional study. Settings: Department of Orthopaedic Sheikh Khalifa Bin Zaid/CMH, Muzaffarabad AJK August 2021 to January 2022. Methods: Patients aged 18 to 65 years with absence of musculoskeletal abnormalities or previous surgeries affecting limb length was recruited for this study. Anthropometric measurements were obtained using standardized techniques. Measurements were taken by trained personnel using calibrated instruments to ensure accuracy and consistency. We used the Pearson correlation coefficient for data analysis Collected data was analysed in SPSS version 22. Results: The study comprised 55 individuals, with 47 being males (85.5%) and 8 being females (14.5%). The mean age of the individuals who participated was 40.4 ± 9.06 years. The mean length of the forearm and little finger combined was 40.66 cm, with a standard variation of 1.70. The observed lengths ranged from 38 cm to 44 cm. The mean femoral length was 40.85 cm, with a standard variation of 2.23 cm. The range of femoral lengths observed ranged from 38 cm to 45 cm. An important and strong positive relationship was revealed (correlation coefficient r = 0.899, p < 0.001). Conclusion: Our study establishes a significant positive correlation of forearm and little finger length in relation to femoral length, highlighting the interplay between upper and lower limb dimensions.
