SURGICAL OUTCOME OF DISPLACED CLAVICLE SHAFT FRACTURES: A COMPARATIVE STUDY OF INFRACLAVICULAR AND DIRECT APPROACH

Abstract

Introduction: Clavicle fractures represent 5% of fractures in adults and almost 44% of shoulder injuries and are usually treated none operatively with good results. However significantly displaced fractures can be associated with high non-union rate and there is a lack of consensus on when surgical treatment is indicated for such fractures. The aim of this study was to identify guidelines for surgical intervention, safer surgical approach and outcome of surgical intervention.

Method: A retrospective audit of all clavicle fractures managed surgically over past 5 years (March 2004 to 2009) in a district general hospital. Case notes were reviewed to study the surgical indication, surgical approach, patient satisfaction and oxford should score and need for metal work removal.

In all 35 patients (29 male) underwent surgery for significant fracture displacement with shortening, manual workers and keen sportsmen at the time of injury. The infraclavicular approach was used in 21 patients and 14 patients had direct incision approach. Radiological union was achieved in all patients after an average of 13.26(8–24) weeks. Six patients required plate removal at 6 months following surgery, infraclavicular (2 patients) & direct approach (4 patients). All patients returned to their original occupation at average 2.55 months. The Oxford Shoulder Score at 3 months after surgery was average 15 (range12–20) and all patients, except one, scored excellent on subjective scoring.

Conclusion: Our study showed excellent surgical outcome for displaced clavicle fractures in young and active patients and is supported by the high union rate, good oxford shoulder score, early return to work and high patient satisfaction scores. The infraclaviculr approach is a betterthan direct approach based on the low complication rate and less need for metal work removal.
