Abstract

PURPOSE. To assess the correlation between the forearm plus little finger length and the femoral length in 100 volunteers. METHODS. The forearm plus little finger length and the ipsilateral femoral length of 68 male and 32 female volunteers aged 19 to 55 (mean, 35.8) years were measured using a measuring tape. The forearm plus litter finger length was measured from the tip of the olecranon to the tip of the little finger, whereas the femoral length was measured from the tip of the greater trochanter to the level of proximal pole of the patella over the outer aspect of thigh. Two observers made the measurements on 2 separate occasions. Intra- and inter-observer variations were calculated. A value of 0.75 or greater indicated excellent agreement. RESULTS. The mean forearm plus little finger length and femoral length were 39.87 (SD, 2.73) and 39.85 (SD, 2.44) cm, respectively. The mean difference between these 2 measurements was 0.028 (95% CI, -0.109 to 0.165) cm. The correlation between these 2 measurements was 0.861 (p<0.001). Patient age, sex, and body mass index did not affect this correlation. The intra- and inter-observer reliability was excellent. CONCLUSION. The forearm plus little finger length correlated with the femoral length. This method is simple, radiation-free, and can be applied in day-today practice.
