Increase in surgical fixation of pediatric midshaft clavicle fractures since 2008.

BACKGROUND: Clavicle fractures in children have traditionally been treated non-operatively. In adults, a great increase in operative treatment has been reported. We aimed to analyze the respective trend and potential explanatory factors in children. METHODS: This is a single-institution retrospective study in a subregion in Northern Finland. The ICD-code S42.0 was used to identify the cases in the hospital registry. Altogether, 214 children, aged < 16, with consecutive clavicle fractures were first enrolled in the area during 2008-2019. Hospital journals and radiographs were reviewed. After lateral and medial fractures and patients living outside the area were excluded, final study population was 172. The respective population at risk was extracted by Statistics Finland. Predictive factors and annual rates of operative treatment as adjusted for 100,000 children at risk were determined. RESULTS: The rate of the surgical treatment of clavicle fractures increased from zero in 2008 to 10.8 in 2019 per 100,000 age-adjusted children (ß = 0.864, 95% confidential intervals (CI) 0.4 to 1.4). There was a rise in the rate of surgery from 2.6% (2014-16) to 16.1% (2017-19) (diff. 13.5, 95% CI 1.7 to 23.3%). A displacement > 15 mm and a shortening of > 15 mm were associated with the increased risk of surgery but did not change during the study period. Age > 9 years increased the risk of surgery; the mean age increased from 5.5 years (2008-10) to 8.5 years (2017-19). There was a 3.6-fold increase in sports-related fractures (95% CI 7.4 to 26.4). The severity of the fractures did not change. CONCLUSIONS: There has been an increasing trend in the surgical fixation of pediatric middle shaft clavicle fractures since 2008. The available literature does not support the trend.

A Shift From Non-operative Care to Surgical Fixation of Pediatric Humeral Shaft Fractures Even Though Their Severity Has Not Changed.

Introduction: Humeral shaft fractures have traditionally been treated non-operatively due to their good union and low rate of functional impairment. In the recent years, upper extremity fractures and their operative treatment have increased in children. Nevertheless, the trends of humeral shaft fractures are not clear. Materials and Methods: All children aged <16 years, with a humeral shaft fracture in the geographical catchment area of Northern Finland Hospital District, with a yearly child population-at-risk of ~86 000 from the year 2001 until the end of 2015 were included. There were 88 cases, who comprised the study population. Radiographs were available of all. Injury, patient, and treatment characteristics were reviewed from hospital databases. Results: There was an increasing trend of surgical fixation of humeral shaft fractures during the 15 years' study period (ß = 1.266, 95% CI 0.17 to 2.36, p = 0.035). However, we found no patient or fracture-related reasons that could have explained the increasing trend of surgical care. Comminuted fracture increased the risk of operative treatment 8-fold (Odds Ratio, OR 7.82, 95% CI 1.69 to 36.3, p = 0.009). Higher age, greater angular deformity or greater diameter of the humerus were not associated with the increased operation risk. Conclusions: The treatment philosophy concerning pediatric humeral shaft fractures has presented a shift from conservative care to surgical fixation. To authors' understanding there is not evidence supporting the increasing rate of osteosynthesis.
