    Abstract: Progressive displacement of diaphyseal clavicle fractures has been observed in adult patients, at times necessitating a change from non-operative to operative treatment. Whether this occurs in adolescent patients has not been well investigated. Purpose: The purpose of this study was to assess the rate and extent of progressive clavicle fracture displacement in adolescent patients following injury and during the early stages of healing. Methods: This was an IRB approved multi-center study evaluating prospective data that had previously been collected as part of a larger study evaluating the functional outcomes of adolescent clavicle fractures. A consecutive series of completely displaced diaphyseal clavicle fractures in patients age 10-18 years treated at one of three tertiary care pediatric trauma centers were included; all of which had standardized imaging within 2 weeks of the date of injury and throughout the course of healing (5-20 weeks post-injury). Measurements of clavicle shortening, superior displacement, and angulation were performed using validated techniques. Progressive displacement and/or interval improvement in fracture alignment were noted, as well as the subsequent need for surgical intervention. Patient demographic and radiographic parameters were assessed as possible risk factors for interval displacement. Results: One hundred patients met the inclusion criteria. The mean shortening, superior displacement, and angulation at the time of injury were 24 mm, 15 mm, and 7°, respectively. At a mean of 10 weeks post-injury, the fracture alignment improved across all three measurements for the overall cohort, with mean improvements in shortening of 15%, superior displacement of 15%, and angulation of 21% (Figures 1,2,3) Using a clinical threshold of a change in shortening or displacement of 10 mm or angulation of 10 degrees, 21% of fractures improved, 4% worsened, and 75% remain unchanged. Patients with more severe fractures were more likely to have improved alignment than less displaced fractures (p 〈 0.001). No patient underwent surgical intervention for progressive displacement. Conclusions: Significant early improvements in fracture alignment were observed in a substantial percentage of adolescent patients with completely displaced clavicle fractures. Among the most severely displaced fractures, a 20% improvement in shortening and 50% improvement in angulation was identified. In 4% of cases, increased displacement was observed, but this tended to be mild, and in no cases did it prompt surgical intervention. This finding indicates that the true final deformity after an adolescent clavicle fracture is commonly less than that present at the time of injury.

    Abstract: The majority of previous investigations on operative fixation of clavicle fractures have been related to the adult population, with occasional assessments of the younger, more commonly affected adolescent population. Despite limited prospective data for adolescents, the incidence of operative fixation of adolescent diaphyseal clavicle fractures has increased. Purpose: To detail the demographic features and descriptive epidemiology of a large pooled cohort of adolescent patients with diaphyseal clavicle fractures presenting to pediatric tertiary care centers in the United States through an observational, prospective, multicenter cohort study (Function after Adolescent Clavicle Trauma and Surgery [FACTS]). Study Design: Cross-sectional study; Level of evidence, 4. Methods: Patients aged 10 to 18 years who were treated for a diaphyseal clavicle fracture between August 2013 and February 2016 at 1 of 8 geographically diverse, high-volume, tertiary care pediatric centers were screened. Treatment was rendered by any of the pediatric orthopaedic providers at each of the 8 institutions, which totaled more than 50 different providers. Age, sex, race, ethnicity, fracture laterality, hand dominance, mechanism of injury, injury activity, athletic participation, fracture characteristics, and treatment decisions were prospectively recorded in those who were eligible and consented to enroll. Results: A total of 545 patients were included in the cohort. The mean age of the study population was 14.1 ± 2.1 years, and 79% were male. Fractures occurred on the nondominant side (56%) more frequently than the dominant side (44%). Sport was the predominant activity during which the injury occurred (66%), followed by horseplay (12%) and biking (6%). The primary mechanism of injury was a direct blow/hit to the shoulder (60%). Overall, 54% were completely displaced fractures, defined as fractures with no anatomic cortical contact between fragments. Mean shortening within the completely displaced group was 21.9 mm when measuring the distance between fragment ends (end to end) and 12.4 mm when measuring the distance between the fragment end to the corresponding cortical defect (cortex to corresponding cortex) on the other fragment (ie, true shortening). Comminution was present in 18% of all fractures. While 83% of all clavicle fractures were treated nonoperatively, 32% of completely displaced fractures underwent open reduction and internal fixation. Conclusion: Adolescent clavicle fractures occurred more commonly in male patients during sports, secondary to a direct blow to the shoulder, and on the nondominant side. Slightly more than half of these fractures were completely displaced, and approximately one-fifth were comminuted. Within this large cohort, approximately one-third of patients with completely displaced fractures underwent surgery, allowing for future prospective comparative analyses of radiographic, clinical, and functional outcomes.

    Abstract: Clavicle fractures are common in children and adolescents and are traditionally treated nonoperatively. With youth sports participation increasing in popularity, including contact sports, the frequency of such injuries may be increasing. The purpose of this study was to examine institutional trends in the volume of operative plate fixation for mid-shaft clavicle fractures in children and adolescents. Methods: Medical records, identified through a departmental database and cross-referenced for accuracy against billing records using ICD-9 codes, were retrospectively reviewed to identify otherwise healthy 10-18 years-olds who presented with a clavicle shaft fracture between 1999-2011 at a single tertiary-care pediatric hospital. Demographic data, fracture characteristics and treatment details were analyzed. Radiographic review of operative cases was used to confirm fracture location and surgical implant. Annual volumes were determined for the overall number of clavicle fractures, mid-shaft clavicle fractures, and mid-shaft fractures that underwent operative plate fixation. Additionally, the annual rate was determined for the number of operative cases among all mid-shaft fractures. Kendall’s Tau-b was used to assess the relationship between case volume and time. Results: From 1999-2011, a total of 882 patients were seen at our institution with a diaphyseal clavicle fracture (mean age: 14.3), 644 (73%) of which were mid-shaft. Of these 644, 111 were treated with operative plate fixation (mean age: 15.9). There was a significant increase in the number of mid-shaft clavicle fractures seen annually over that period, from 20/yr to 85/yr (r=0.80, p 〈 0.0001). The percent of mid-shaft clavicle fractures treated with plate fixation also increased significantly from 5% to 25% (r=0.84, p 〈 0.0001) while the rate of mid-shaft fractures among all diaphyseal fractures remained more stable. Among the mid-shaft fracture cases that received operative plate fixation, 53.2% presented with fractures received during a competitive sporting event. Conclusion: The volumes of clavicle fractures and of mid-shaft clavicle fractures treated operatively appear to be increasing. Additionally, despite a lack of evidence based support, the frequency of operative plate fixation of mid-shaft clavicle fractures appear to be increasing in the pediatric population. Many of these fractures are of a sports-based etiology.

    Abstract: To investigate the two-year functional outcomes and complications following operative versus non-operative treatment of completely displaced midshaft clavicle fractures in adolescents. Methods: All patients 10-18 years-old treated for a midshaft clavicle fracture between August, 2013 and August, 2018 at one of 8 geographically diverse, high-volume, tertiary-care pediatric centers were enrolled, with independent treatment decisions determined by individual providers. The sub-population of patients with completely displaced fractures was prospectively followed for over 2 years. Clinical course, complications, validated patient-reported outcome measures (PROs), quality of life metrics, and satisfaction scores were analyzed. To address the ceiling effect of the PRO/satisfaction data following clavicle injuries, a priori thresholds for ‘suboptimal’ scores were established (ASES scores 〈 90, QuickDASH scores 〉 10, EQ-5D 〈 0.80). According to ‘intention to treat’ statistical principles, one post-operative complication (and a subsequent secondary operation) was analyzed within the non-operative cohort, given that the patient represented a ‘crossover’ from the non-operative to the operative treatment group. Results: Of the 909 patients enrolled in the prospective study, 417 patients (45.9%) demonstrated completely displaced fractures and maintained enrollment over the study period, 277 (66%) of whom had reached two year follow up, and 151 of whom provided adequate PRO data, representing a 55% response rate. Of these patients, 55 (36%) underwent operative treatment, while 96 (64%) were treated non-operatively. Those treated surgically showed no difference in gender distribution (76% males,p=0.43), athletic participation (p=0.76), or fracture pattern (p=0.18), but were older (mean age 15.3 vs. 13.5 years, p 〈 0.001) and had greater shortening (p 〈 0.001) than those treated non-operatively. Within the subset with adequate complication data, listed in Figure 1, complications were less common in non-surgical than surgical patients (p=0.0003), but this difference did not reach significance when sensory deficits were excluded (p=0.17). There was no difference in secondary surgeries (p=0.43). While greater percentages of operative than non-operative patients reported suboptimal PRO/satisfaction scores (ASES: 15% vs. 5%, QuickDASH 11% vs 5%, satisfaction 11% vs. 5%), these differences did not reach significance (p=0.07, 0.20, 0.06, respectively). Conclusion: At eight large pediatric centers with many surgeons making independent treatment decisions, non-operative treatment of adolescent clavicle fractures demonstrated lower complication rates and similar satisfaction and functional outcomes.These data establish a comprehensive functional assessment of adolescents treated for clavicle fractures, which represents the epidemiological sub-population most affected by this condition. Unlike several adult studies demonstrating superiority in operative treatment, this adolescent study demonstrates equivalent function and fewer complications associated with non-operative treatment.

    Abstract: The optimal treatment of midshaft clavicle fractures is controversial. Few previous comparative functional outcome studies have investigated these fractures in adolescents, the most commonly affected epidemiologic subpopulation. Purpose/Hypothesis: The purpose was to prospectively compare the outcomes of operative versus nonoperative treatment in adolescents with completely displaced midshaft clavicle fractures. The study hypothesis was that surgery would yield superior outcomes. Study Design: Cohort study; Level of evidence, 2. Methods: Patients aged 10 to 18 years treated for a midshaft clavicle fracture over a 5-year period at 1 of 8 pediatric centers were prospectively screened, with independent treatment decisions determined by individual musculoskeletal professionals. Demographics, radiographic clinical features, complications, and patient-reported outcomes (PROs) were prospectively recorded for 2 years. Regression and matching techniques were utilized to adjust for potential age- and fracture severity–based confounders for creation of comparable subgroups for analysis. Results: Of 416 adolescents with completely displaced midshaft clavicle fractures, 282 (68) provided 2-year PRO data. Operative patients (n = 88; 31%) demonstrated no difference in sex (78% male) or athletic participation but were older (mean age, 15.2 vs 13.5 years; P 〈 .001), had more comminuted fractures (49.4% vs 26.3%; P 〈 .001), and had greater fracture shortening (25.5 vs 20.7 mm; P 〈 .001) than nonoperative patients (n = 194; 69%). There was no difference in mean PRO scores or rates of “suboptimal” scores (based on threshold values established a priori) between the operative and nonoperative treatment groups (American Shoulder and Elbow Surgeons, 96.8 vs 98.4; shortened version of the Disabilities of the Arm, Shoulder and Hand, 3.0 vs 1.6; EuroQol [EQ] visual analog scale, 93.0 vs 93.9; EQ–5 Dimensions index, 0.96 vs 0.98), even after regression and matching techniques adjusted for confounders. Operative patients had more unexpected subsequent surgery (10.4% vs 1.4%; P = .004) and clinically significant complications (20.8% vs 5.2%; P = .001). Overall, nonunion (0.4%), delayed union (1.9%), symptomatic malunion (0.4%), and refracture (2.6%) were exceedingly rare, with no difference between treatment groups. Conclusion: Surgery demonstrated no benefit in patient-reported quality of life, satisfaction, shoulder-specific function, or prevention of complications after completely displaced clavicle shaft fractures in adolescents at 2 years after injury. Registration: NCT04250415 ( ClinicalTrials.gov identifier).

    Abstract: Bony remodeling of displaced clavicle fractures in adolescents remains poorly understood. Purpose: To evaluate and quantify clavicle remodeling in a large population of adolescents with completely displaced fractures, which were treated nonoperatively, to better understand the factors that may influence this process. Study Design: Case series; Level of evidence, 4. Methods: Patients were identified from the databases of a multicenter study group investigating the functional outcomes of adolescent clavicle fractures. Patients between the ages of 10 and 19 years with completely displaced middiaphyseal clavicle fractures that were treated nonoperatively and who had further radiographic imaging of the affected clavicle at a minimum of 9 months from initial injury were included. Fracture shortening, superior displacement, and angulation were measured on the injury and final follow-up radiographs using previously validated techniques. Furthermore, fracture remodeling was classified as complete/near complete, moderate, or minimal, using an original classification system found to have good to excellent reliability (interobserver reliability = 0.78, intraobserver reliability = 0.90). Classifications were subsequently analyzed quantitatively and qualitatively to determine the factors associated with deformity correction. Results: Ninety-eight patients (mean age, 14.4 ± 2.0 years) were analyzed at a mean radiographic follow-up of 3.4 ± 2.3 years. Fracture shortening, superior displacement, and angulation significantly improved during the follow-up period by 61%, 61%, and 31%, respectively ( P 〈 .001). Furthermore, while 41% of the population had initial fracture shortening 〉 20 mm at final follow-up, only 3% of the cohort had residual shortening 〉 20 mm. Fracture remodeling was found to be associated with follow-up time; those with longer follow-up time demonstrated more remodeling ( P = .001). Eighty-five percent of patients aged 〈 14 years and 54% of patients aged ≥14 years at time of injury with a minimum follow-up of 4 years underwent complete/near-complete remodeling. Conclusion: Significant bony remodeling occurs in adolescent patients with completely displaced clavicle fractures, including older adolescents, and appears to continue over longer time intervals, even beyond the adolescent years. This finding may help explain the low rate of symptomatic malunions in adolescents, even in severely displaced fractures, and particularly when compared with rates reported in adult studies.
