Radiographic Measurement of Lower Limb Length Discrepancy: A Comparison of Three Measurement Techniques for Assessing Total and Segmental Limb Lengths

The authors aimed to compare three radiographic measurement techniques for assessing total and segmental limb lengths in skeletally immature patients with limb length discrepancy (LLD). They found that while all three methods yielded comparable results, subtle differences were noted, particularly in relation to lower limb angular deformities. The study emphasizes the importance of consistently using a single measurement technique to minimize variability in LLD estimation.
