Residual coracoclavicular separation after plate fixation for distal clavicle fractures: comparison between fracture patterns

Abstract Background Plate fixation is the established method of treating unstable distal clavicle fractures. However, the appropriate timing of surgery for acute distal clavicle fractures remains unclear. The present study aimed to evaluate the clinical outcomes of osteosynthesis using a Scorpion plate and to assess the influence of surgery timing on the surgical outcomes for acute unstable distal clavicle fractures. Methods We retrospectively reviewed 105 patients who underwent fixation for acute unstable distal clavicle fractures (Neer type II and V) using the Scorpion plate between 2008 and 2018. Patients were divided into early (45 patients) and delayed (60 patients) treatment groups based on the timing of the surgical intervention (within or after seven days). The outcomes were postoperative complications (delayed union, peri-implant fracture, plate loosening, plate-related pain, and stiffness). We evaluated the outcomes from X-ray radiographs and clinical notes.Results Among the 105 patients, delayed union, plate loosening, plate-related pain, and stiffness were observed in six patients (5.7%), four patients (3.8%), seven patients (6.7%), and one (1.0%) patient, respectively. The delayed union rate was significantly higher in the delayed treatment group than that in the early treatment group (P=0.036). Although the difference was not significant, plate loosening and stiffness were only observed in the delayed treatment group. Conclusion Our results demonstrated that osteosynthesis using Scorpion plates achieved satisfactory surgical outcomes for unstable distal clavicle fractures . In addition, this study suggested that performing surgery within six days after injury is recommended to reduce postoperative complications .

Distal Clavicle Fractures

Background: The coracoclavicular fixation with suture anchors adds stability to type IIb distal clavicle fractures fixed with a plate and screws when loaded to failure. The purpose of this study was to compare the clinical and radiological outcomes between the use of a locking compression plate (LCP) with all-suture anchor fixation and hook LCP fixation of Neer IIb distal clavicle fractures. Methods: A total of 82 consecutive patients who underwent plate fixation for Neer IIb distal clavicle fractures were included. The subjects were divided into two groups: an LCP with all-suture anchor fixation group and hook LCP fixation group. For clinical assessments, the American Shoulder and Elbow Surgeons score, Korean shoulder score (KSS), and Constant score were recorded. A percentage of the coracoclavicular distance (CCD%) was used to evaluate fracture reduction. Typical reported complications, such as secondary dislocation, implant failure or loosening, peri-implant fracture, acromion osteolysis, stiffness, peri-anchor osteolysis, postoperative acromioclavicular joint arthrosis, nonunion, or delayed union, were also analyzed. Results: There were no differences in the clinical and radiological outcomes at the final follow-up between the two groups. The period for bone union and CCD% showed no significant differences between groups. Stiffness at 3 months after surgery of LCP with all-suture anchor fixation ( n = 3, 10.7%) was less than that of hook LCP fixation ( n = 17, 31.5%). The complication rate also showed no significant differences between groups. However, LCP with all-suture anchor fixation had anchor-related complications, although it can reduce hook-related complications. Conclusion: LCP with all-suture anchor fixation showed satisfactory outcomes in comparison with hook LCP fixation. In Neer IIb distal clavicle fractures, LCP with all-suture anchor fixation is a useful method for the maintenance of reduction, avoiding implant removal, and hook-related complications. However, anchor fixation should be carefully used, especially in osteoporotic patients or patients with underlying diseases. Level of Evidence: Level III, retrospective study.
