Introduction

Clavicle fractures accounting for 3–5% of all adult fractures are usually treated non-operatively. There is an increasing trend towards their surgical fixation.

Background:. Displaced midshaft clavicle fractures unite well in children less than 12 years old, owing to their inherent ability to remodel bone. In adolescents, remodeling occurs less and deformity or shortening can result. Recent literature in adults shows improved outcomes of these fractures with operative treatment. It has been suggested that these results may translate to adolescents. Study Objective:. To assess the effectiveness of titanium elastic TEN nails in the treatment of displaced midshaft clavicle fractures in adolescents. Methods:. Adolescent patients (age 12 to 18) with closed displaced midshaft clavicle fractures, sustained between 2008 and 2014, were treated operatively by a single surgeon, who inserted a TEN nail in an unreamed fashion from the sternal end of the clavicle. Post-operatively, patients were immobilised in a sling for 6 weeks. The nail was removed routinely at 12 weeks. All patients were assessed by the surgeon at 24 weeks with regards to the radiological outcome, Constant shoulder score, scar quality and complications. Results:. Thirteen patients, 9 males and 4 females (mean age 14,2 years) were assessed. Eleven patients had complete union by 6 weeks and the remaining two by 12 weeks. The Constant score was graded below 11 for all patients by 12 weeks follow up and all patients were satisfied with their scars after 24 weeks. Two patients developed complications: in one, the nail perforated the posterior cortex of the lateral fragment and the other developed a haematoma. Conclusion:. Operative treatment with a TEN nail is a safe, minimally invasive and reliable treatment method for displaced midshaft clavicle fractures in adolescents resulting in a satisfactory surgical outcome

Purpose. Displaced midshaft clavicular fractures are a common injury with a high occurrence rate in young, active individuals. Non-operative care has traditionally been the standard of care for such fractures, but more recent studies have suggested benefits following primary operative fixation. The purpose of this study was to review the literature on displaced midshaft clavicle fractures, identify randomized controlled trials of operative versus non-operative treatment, and pool the functional outcome and complication rates (including nonunion and symptomatic malunion), to arrive at summary estimates of these outcomes. Method. A systematic review of the literature was performed to identify studies of randomized controlled trials comparing operative versus non-operative care for displaced midshaft clavicle fractures. Meeting abstracts were also searched and included in this study. Results. Six randomized controlled trials (n=421 patients, mean Detsky score= 15.2) were identified and included. The nonunion rate was higher in the non-operative group (28/207) then it was in patients treated operatively (3/214) (p<0.001). The rate of symptomatic malunion was higher in the non-operative group (15/207) than the operative group (0/214) (p<0.001). The total complication rate was 71 complications in 214 operative cases (33%), and 93 complications in 207 non-operative cases (45%)(p=0.016). The Constant Shoulder scores (CS) and Disability of the Arm, Shoulder and Hand (DASH) scores showed marginally improved (mean 4.1 point increase in CS at one year, mean 5.8 point decrease in DASH at one year) functional values in the operative group: this difference was especially marked in the early post operative period. Conclusion. Operative treatment provided lower complication rates (especially nonunion and symptomatic malunion) and an earlier functional return compared to non-operative treatment. However, there is little evidence at present to show that the long term effects of operative intervention are significantly superior to non-operative care

Midshaft clavicle fractures can be classified into simple or complex/comminuted. The hardest fracture to treat is the severely comminuted and displaced fracture. We retrospectively compared 286 consecutive operatively treated simple (2 and 3 part) fractures with the more complex comminuted (>=4 part) midshaft clavicle fractures, looking at outcome, complication rate and union rate. Between 2008 and 2010 the senior author operated on 286 displaced midshaft clavicle fractures using a plate and screws. In this cohort there were 173 simple (2 and 3 part) fractures and 99 complex (>=4 part) fractures. The operation was performed through a limited incision technique and was standardized. All fractures were fixed with at least 3 screws on either side of the comminution. All patients were up until radiological and clinical union. A standardized questionnaire was used to assess patient satisfaction, return to work, sport and outcome at each postoperative visit. All complications were documented. All fractures eventually went onto union. There were 242 males and 44 females with the average age being 33. The complex fractures had a larger scar, took longer to return to normal motion, work and sport, and took on average 10 weeks to unite compared to 6 weeks in the simple fractures. The infection rate in the simple fractures was 1% and in the complex fractures was 2%. The big difference was the incidence of non union in the complex fractures of 10% compared to 1%; the other main difference was postoperative shoulder stiffness of 3% at 3 months in the complex fractures compared to 1 % in the simple fractures. Plate elevation/irritation was also more prevalent in the complex fractures of 10% compared to 3%. This study clearly shows there is a higher complication rate in complex fractures. Particular attention must be placed on surgical technique and anatomical reduction of these difficult fractures followed closely by postoperative rehabilitation. Future studies of clavicle fractures should specify the type of fracture being treated to give a better understanding of the potential outcome
