Abstract
Introduction
Clavicle fractures can cause pain and functional impairment if not managed appropriately. This paper evaluates the prevalence of clavicular fractures, estimates number of cases requiring operative treatment, whether removal of implant is a frequent necessity and compares the final functional outcome of the operative and non-operative group.
Materials/Methods
Between November 2005 and November 2007 patients with clavicular fractures were eligible for participation. Patients below 18 years of age, and pathological fractures were excluded. Operative versus non-operative treatment, radiographic classification (Allman system), complications, implant removal, and functional outcome using the University of California Los Angeles (UCLA) shoulder scores were documented and analysed.
Results
Out of 16,280 fractures presenting to our University Teaching Hospitals, 200 (1.23%) met the inclusion criteria. Twenty patients were lost due to natural attrition, 159 (88.3%) patients were treated non-operatively and 21 (11.7%) patients operated upon, over half for symptomatic non-union. All clavicles united post operatively. Eighty one conservatively managed undisplaced medial, middle and lateral end fractures had excellent mean UCLA shoulder scores. A statistical significance in UCLA scores (p<0.05) was noted between the operative and non-operative groups in mid shaft fractures. Under half (42.9%) required removal of metal implant sue to soft tissue irritation with complete resolution of symptoms.
Conclusion
The incidence of clavicle fractures was 1.23%. A small number of patients (11.7%) required operative treatment. We recommend surgical management of symptomatic non-union and removal of metal implant for hard ware related symptoms.
