Purpose Of The StudyThe authors review and evaluate the operative treatment of mid-shaft clavicular non-union by compression plate osteosynthesis and most frequently by decortication and autogenous bone grafting.Material And MethodsFrom 1979 to 1990, 11 consecutive patients, 9 males and 2 females, mean age 33.5 years, with symptomatic non-union of mid-shaft clavicular fracture were operated and followed-up for an average of 4 years. The pseudarthrosis was atrophic in 10 and hypertrophic in 1 patient. The initial treatment of the fracture was always conservative.ResultsAll patients achieved bone union by 3-7 months post operatively. The functional results were excellent in 9 patients. The remaining two patients had mild symptoms such as occasional pain related to weather, soreness of the muscles with overhead lifting and discomfort of the shoulder. Minor complications were noted such as 1 delayed wound healing, 3 cheloid scars and 1 transient partial paresis of the brachial plexus.DiscussionSymptomatic non-union of the mid-shaft clavicular is a rare complication, mainly after non-operative treatment (11 cases in 12 years in our series). Factors responsible for non-union are the initial high velocity injury, the cominution, the overlapping and great displacement, the paucity of cancellous bone at this site and the trapezius interposition. Internal fixation by compression plating, decortication and bone grafting in atrophic non-union often encountered is a safe reliable method allowing uncomplicated healing and acceptable functional results.
