Acute operative stabilization versus nonoperative management of clavicle fractures. The management of acute acromioclavicular dislocation. A randomised prospective controlled trial. Elastic stable intramedullary nailing versus nonoperative treatment of displaced midshaft clavicular fractures-a randomized, controlled, clinical trial.
We conducted a prospective, randomized study to determine if patients with midshaft clavicle fractures would benefit from immediate operative stabilization with a modified Hagie pin in comparison with a matched group treated with nonoperative therapy. At a level II trauma center, patients with closed midshaft clavicle fractures were prospectively randomized to receive either operative or nonoperative treatment. Fifty-seven (29 operative, 28 nonoperative) patients were enrolled in the study. Operative patients underwent open reduction and internal fixation of the clavicle using a modified Hagie pin; nonoperative patients were treated with a sling for comfort. All patients were followed at regular intervals for 1 year. They were evaluated for radiographic healing and complications and were scored with the Single Assessment Numeric Evaluation and L'Insalata instruments. Injury severities and radiographs were not statistically significantly different between the 2 groups. Functional scores in the operative group were slightly higher at 3 weeks, and the nonoperative group had slightly higher scores at 6 months and 1 year. The only statistically significant difference between the groups was at 3 weeks. Percentage follow-up at 1 year was 93% for the operative group and 82% for the nonoperative group. One patient in each group developed a nonunion, and 1 patient in each group had a refracture. Complications were higher in the operative group, and most were related to pin prominence at the posterior shoulder. Results of this study suggest that, though patients with midshaft clavicle fractures had higher functional scores at short-term follow-up after internal fixation, functional scores were similar at 6 months and 1 year. In addition, internal fixation with a modified Hagie pin was associated with a higher complication rate. In a prospective study, 60 patients with acute acromioclavicular dislocation were randomly allocated to treatment with a broad arm sling or to reduction and fixation with a coracoclavicular screw. Of these 54 were followed for four years. Conservatively-treated patients regained movement significantly more quickly and fully, returned to work and sport earlier and had fewer unsatisfactory results than those having early operation. For severe dislocations, with acromioclavicular displacement of 2 cm or more, early surgery produced better results. Conservative management is best for most acute dislocations, but younger patients with severe displacement may benefit from early reduction and stabilisation. To compare elastic stable intramedullary nailing (ESIN) with nonoperative treatment of fully displaced midshaft clavicular fractures in adults.
                The study was a randomized, controlled, clinical trial.
                Level 1 trauma center.
                Sixty patients between 18 and 65 years of age participated and completed the study. They were randomized to either operative or nonoperative treatment with a 2-year follow-up.
                Thirty patients were treated with a simple shoulder sling and 30 patients with ESIN within 3 days after trauma.
                Complications after operative and nonoperative treatments, Disabilities of the Arm, Shoulder and Hand (DASH) score and Constant Shoulder Score for outcome measurement, and clavicular shortening.
                Fracture union was achieved in all patients in the operative group, whereas nonunion was observed in 3 of 30 patients of the nonoperative group. Two symptomatic malunions required corrective osteotomy in the nonoperative group. Medial nail protrusion occurred in 7 cases in the operative group. Implant failure with revision surgery was necessary in 2 patients after an additional adequate trauma. DASH scores were lower in the operative group throughout the first 6 months and 2 years after trauma, with a significant difference during the first 18 weeks. Constant scores were significantly higher after 6 months and 2 years after intramedullary stabilization. Patients in the operative group showed a significant improvement of posttraumatic clavicular shortening; they were also more satisfied with cosmetic appearance and overall outcome.
                ESIN of displaced midshaft clavicular fractures resulted in a lower rate of nonunion and delayed union, a faster return to daily activities, and a better functional outcome. Clavicular shortening was significantly lower, and overall satisfaction was higher in the operative group.
There is insufficient evidence from randomised controlled trials to determine which methods of conservative treatment are the most appropriate for acute middle third clavicle fractures in adolescents and adults. Further research is warranted.
