Abstract

Background: Accurate preoperative nail estimation has the potential to reduce intra-operative errors, operative time and radiation exposure.

Objectives: The study aims to determine the accuracy and correlation of the 6 anthropometric parameters to the ideal tibial IM nail length based on the AP scanogram of the tibia.

Methodology: Six anthropometric parameters were measured in 15 males and 15 females: knee joint line to the ankle joint line distance (KAD), knee joint line to the medial malleolus distance (KMD), tibial tuberosity to the ankle joint line distance (TAD), tibial tuberosity to the medial malleolus distance (TMD), olecranon tip to the head of the 5th metacarpal distance (OMD), body height (BH). The ideal tibial IM nail length was determined using the AP scanogram of the ipsilateral tibia measured as 10 mm from the proximal tibial articular surface and 10 mm from the distal tibial articular surface of the AP scanogram film of the tibia using the metal radiographic ruler as measuring tool. A regression equation was applied to BH measurements.

Results: Accuracy of BH regression equations recommended by other authors were calculated in the study. It was found out that the six anthropometric parameters have poor accuracy: KAD 27% (CI 32.59 - 34.24), OMD 13% (CI 31. 36 - 32.84) and KMD 7% (CI 33.79 - 35.31). The predicted nail length using BH regression (CI 29.26 - 30.41), TAD (CI 29.79 - 31.07) and TMD (CI 30.94 - 32.19) are not accurate with 0% accuracy.

Conclusion: KMD, KAD and OMD when taken altogether, are useful for estimating the range of tibial IM nail lengths. There was a strong correlation between the 6 anthropometric parameters and the ideal tibial IM nail length with KMD (r = .892, p = .000) having the highest correlation.
