Abstract Background Although of great value in the management of lateral clavicle fractures, substantial variation in their classification exists. We performed a retrospective study to address the inter- and intraobserver reliability of three different classification systems for lateral clavicle fractures. Methods Radiographs of 20 lateral clavicle fractures that represented a full spectrum of adult fracture patterns were graded by five experienced radiologists and five experienced trauma surgeons according to the Orthopaedic Trauma Association (OTA), the Neer, and the Jäger/Breitner classification systems. This evaluation was performed at two different time points separated by 3 months. To measure the observer agreement, the Fleiss kappa coefficient (κ) was applied and assessed according to the grading of Landis and Koch. Results The overall interobserver reliability showed a fair agreement in all three classification systems. For the OTA classification system, the interobserver agreement showed a mean kappa value of 0.338 ranging from 0.350 (radiologists) to 0.374 (trauma surgeons). Kappa values of the interobserver agreement for the Neer classification system ranged from 0.238 (trauma surgeons) to 0.276 (radiologists) with a mean κ of 0.278. The Jäger/Breitner classification system demonstrated a mean kappa value of 0.330 ranging from 0.306 (trauma surgeons) to 0.382 (radiologists). The overall intraobserver reliability was moderate for the OTA and the Jäger/Breitner classification systems, while the overall intraobserver reliability for the Neer classification system was fair. The kappa values of the intraobserver agreements showed, in all classification systems, a wide range with the OTA classification system ranging from 0.086 to 0.634, the Neer classification system ranging from 0.137 to 0.448, and a range from 0.154 to 0.625 of the Jäger/Breitner classification system. Conclusions The low inter- and intraobserver agreement levels exhibited in all three classification systems by both specialist groups suggest that the tested lateral clavicle fracture classification systems are unreliable and, therefore, of limited value. We should recognize there is considerable inconsistency in how physicians classify lateral clavicle fractures and therefore any conclusions based on these classifications should be recognized as being somewhat subjective.

Clavicle Fractures

Background: Although clavicle fractures are a common sports injury, there are limited studies on the incidence and causes of clavicle fractures among winter sports athletes. Purpose: To evaluate the characteristics and injury mechanisms associated with clavicle fractures among patients evaluated at a Colorado ski resort. Study Design: Descriptive epidemiology study. Methods: This was a retrospective descriptive analysis of patients with clavicle fractures at the Denver Health Winter Park Medical Center during the 2012-2013 to 2016-2017 ski seasons. Chart review was performed on the patient cohort to confirm clavicle fracture diagnosis and to evaluate factors associated with clavicle fracture. Results: A total of 393 clavicle fractures (6.2% of total clinic visits) occurred during the study period, corresponding to an overall clavicle fracture incidence of 8.4 per 100,000 participant-visits. The mean patient age was 26.4 years (range, 5-73 years). The majority were middle-third fractures (85.5%), occurring mainly in men (87.3%). More than half of the fractures were comminuted (54.5%) and occurred in snowboarders (55.0%). The most common mechanism of injury was a fall onto snow while skiing or snowboarding (92.4%). Women sustained more clavicle fractures while skiing compared with snowboarding (82.0% vs 18.0%; P < .001), while men sustained more fractures while snowboarding compared with skiing (60.3% vs 39.7%; P < .001). Conclusion: Clavicle fractures are relatively common, but there are scant incidence data for clavicle fractures in mountain sports. Consistent with prior studies, clavicle fractures were more common in younger patients and men. The most common anatomic fracture location was the midclavicle. A greater proportion of clavicle fractures among men were sustained during snowboarding and among women during skiing.
