Background. Most studies addressing the composition and volume of an amputated limb in lower extrem- ity amputations have focused on determining the amputation stump volume. Examination of the weight of the amputated part of the limb is important for guiding the application of a definitive prosthesis. Objectives. To assess the theoretical value of the weight of the amputated part of the lower limb in patients after transtibial amputation. Study design. Cross-sectional study. Methods. 14 patients with transtibial amputation were enrolled, along with 14 matching controls. We assessed limb weight using dual-emission X-ray absorptiometry (DXA) and compared these values to those derived using anthropometric models (per Zatsiorsky, Osterkamp, and Mozumdar). Results. The lowest average (± standard deviation) weight determined for the hypothetical distal part of the amputated limb by DXA was –3.11±1.13 kg. Compared to DXA, anthropometric models pro- vided significantly higher values. The highest value (4.85 ± 0.77 kg) resulted from using calculations according to Osterkamp, and the model proposed by Mosumdar gave the lowest value (3.43±0.45), which was closest to that derived using DXA. Conclusion. DXA is generally considered the gold standard for measuring body composition. Our comparison of data measured with DXA to that from anthropometric models shows that calculations of amputa- tion mass using selected anthropometric models can significantly overestimate the weight of an amputated limb.
