Abstract
BACKGROUND: To compile an evaluation system (score) for post-treatment outcomes of midclavicular fractures, 172 patients were studied on average 15 months post-injury. As a control group 45 healthy volunteers were examined. The most relevant elements were filtered out for use in a new classification system, the Clavicle Score (CS). METHODS: The CS is based on a system of three partnered objective/subjective items as well as radiographic assessment of fracture healing. For the partnered items, subjective responses with the most significant correlation to the specific objective parameters were selected. Total score cutoff values (very good, good, moderate, poor) were established to keep interpretation simple. To validate the system, linear regression analysis was performed comparing the CS to two established assessment systems (Constant Score and the DASH Score). ERGEBNISSE: The correlation coefficients R=0.756 (Constant) and R=0.687 indicated that the conclusions were comparable and therefore valid. The reliability coefficient Cronbach's alpha was calculated at 0.8241, indicating high reliability. CONCLUSION: The CS is a simple, valid and reliable instrument to assess outcomes post-midclavicular fracture.
