Mini-open Treatment Using Plate of Clavicle Mid-shaft Fractures

BACKGROUND: Increased frequency of comminuted clavicle mid-shaft fractures and importance of functional satisfaction through early joint exercise has resulted in higher emphasis on surgical treatments. This study aimed to evaluate the clinical radiological results of treatment of clavicle mid-shaft fractures by open reduction and internal fixation using a plate with a small incision. METHODS: The subjects of this study were 80 clavicle mid-shaft fracture cases treated with internal fixation using a plate from October 2010 to July 2014. Clavicle mid-shaft fractures were internally fixated using anatomical plates or locking compression plates. Achievement of bone union, union period, and clavicle length shortening were evaluated radiologically, and clinical assessment was done by using Constant and University of California at Los Angeles (UCLA) scores. RESULTS: All 80 cases were confirmed to have achieved bone union through radiographs with an average union period of 10.9 weeks (range: 7–18 weeks). The average clavicle length of shortening in the affected side was 1.8 mm (range: 0–17 mm). The average UCLA score and Constant score were 33.6 (range: 25–35) and 92.5 (range: 65–100), respectively. Regarding complications, four cases reported skin irritation by metal plates, and one case reported a screw insertion site fracture due to minor trauma history. CONCLUSIONS: We were able to induce successful bone union and obtain clinically satisfactory results in displaced mid-shaft fractures of the clavicle without major complications such as nonunion through treatment of internal fixation using a plate.

Anatomical Reduction of All Fracture Fragments and Fixation Using Inter-Fragmentary Screw and Plate in Comminuted and Displaced Clavicle Mid-Shaft Fracture

PURPOSE: To report the treatment results of anatomical reduction of all fracture fragments and internal fixation using an inter-fragmentary screw and plate in displaced mid-shaft clavicle fracture with comminution. MATERIALS AND METHODS: Between June 2005 and August 2011, 13 consecutive displaced clavicle fractures with comminution (Edinburgh classification IIB2) treated by anatomic reduction and internal fixation using inter-fragmentary screw and plate were retrospectively evaluated. There were 11 male and 2 female patients with a mean age of 37.4 years (15~55 years). The right clavicle was injured in 4 patients and the dominant arm was involved in 46%. The mean duration from trauma to surgery was 7.0 days. The cause of injury was a traffic accident in three, a fall in two, and sports activity or direct injury in eight patients. All of the fracture pieces were anatomically reduced and fixed with inter-fragmentary screws. An additional plate was applied to maintain and reinforce the reduction of the fracture. Radiographic assessments for the numbers of fragments and the amount of shortening and displacement were performed. To verify the fracture healing and determine the time from fracture surgery to union and complications, all of the radiographs taken after surgery were evaluated. RESULTS: The number of fragments was 2 in 7 cases, 3 in 5 cases, and 6 in one case. The mean shortening of the clavicle was 1.1 cm (0.3~2.1 cm) and mean displacement between the main fragments was 2.6 cm (1.3~4.5 cm). The mean duration of follow-up was 16.5 months (8~26 months). Radiographic union was achieved in all patients with a mean time to union of 10.8 weeks (8~14 weeks). There were no complications including metal failure, nonunion, or infection. CONCLUSION: Anatomical reduction of all the fracture fragments and fixation using inter-fragmentary screws in addition to the usual plate fixation showed good fracture healing in displaced clavicle fracture with comminution.
