Introduction Open reduction and plate fixation is known to reduce chances of malunion and symptomatic nonunion in displaced middle-third clavicle fractures. However, this treatment modality is also associated with several complications, such as hardware irritation, numbness around the surgical scar, infection, nonunion and implant failure. The minimally invasive plate osteosynthesis (MIPO) technique may reduce these complications.Objective To study clinical, radiological and functional outcomes of MIPO in AO/OTA type B displaced clavicle fractures and report any complications.Materials and methods A total of 22 patients underwent internal fixation of acute displaced AO/OTA type B clavicle fractures from Jan 2014 to Dec 2015 by MIPO using locking compression plates. Patients were followed up at a regular interval and assessed clinically and radiologically. The clavicle length difference was measured. Functional assessment was done at the end of 2 year using constant shoulder score (CSS) and disability of the arm, shoulder and hand score (Quick DASH) and complications if any were noted.Results All fractures united at a mean of 12.5 weeks. One (4.5%) patient had numbness around the surgical scar. None of the patients had wound-related complications. In four patients, hardware irritation was noted. The difference in clavicle length was not significant. All patients had excellent CSS and Quick DASH score at the final follow-up.Conclusion Internal fixation of displaced AO/OTA type B clavicle fractures by MIPO showed high fracture union rates and good functional outcomes.
