Introduction: The rising trend of operative fixation of clavicles has raised questions about the clinical effects of shortening and the best methods to measure it. Most surgeons rely on X-rays or clinical examination however Furey., et al. have reported poor correlation between x-rays and CT findings.

Aim: The aim of this study is to test the validity of ultrasound as a quick and non-invasive measurement method in comparison to traditional manual measurements of clavicle length.

Methods: Nineteen cadavers (38 clavicles) were identified for potential inclusion in this study. Data was collected prospectively by two investigators using a standardised technique, the sterno-clavicular and acromio-clavicular joints were identified manually, marked and the lengths of the clavicles were measured using a metal ruler. Next, the markings were erased and the measurements were repeated following the same protocol after identification of the joints using ultrasonography (US). Finally, following dissection, the clavicles were re-measured under direct vision.

Results: We obtained Manual, US aided and direct measurements were taken from 35 clavicles (18 cadavers) using the described technique. Only paired results, either manual or US-aided with a corresponding direct clavicle measurement, were used for comparative analysis. Median clavicle length in all groups was 140 mm (ranges: Manual 130-165, US-aided 110-165, Direct 130-150). Statistical analysis was conducted using parametric tests (GraphPad Software, Inc. CA). We defined statistical significance as a p-value of 0.05 or less. Using a paired t-test, manual measurement (with palpation of adjacent joints) when compared to measurement under direct vision yielded a two tailed p-value of 0.0011, suggesting a very significant difference in the paired measurements. However, US-aided measurement when compared to direct measurement demonstrated no significant difference between the paired measurements (two-tailed p-value = 0.2001).

Conclusion: This study demonstrates that US-aided measurement of clavicle length may be more accurate than traditional manual measurement using palpation of clavicle length. Ultrasound has the benefit of being safe, non-invasive and involves no exposure of the patient to ionizing radiation. This study was conducted in cadavers with the associated limitations. Further study is required to validate these findings in vivo.
