Surgical approach for open reduction and internal fixation of clavicle fractures: a comparison of vertical and horizontal incisions

PurposeThis study was designed to compare the results of clavicle fracture open reduction internal fixation (ORIF) with standard horizontal incision versus vertical incision.MethodsORIF surgery performed between October 2012 and August 2016 was included. The surgical approach was chosen according to surgeon preference as vertical or horizontal. Functional outcomes, fracture union, complications, scar appearance, skin irritation, and denervation around the scar were assessed at a minimum follow-up of three months.ResultsThirty-eight patients, age 3912years, were operatedupon, 22 through vertical incisions and 16 through horizontal incisions. There were no significant group differences in functional scores, fracture union, or complications. Two patients in the vertical incision group had a post-operative haematoma. The scar length was significantly shorter when a vertical incision was used (6.75 +/- 1.25cm vs 8.9 +/- 2.3cm, P=0.001). The typical distribution of hypoesthetic skin area distal and lateral to the scar represented iatrogenic damage to the supraclavicular nerves and was found in 66% of patients. The mean hypoesthetic surface area was smaller in the vertical incision group (38 +/- 29cm(2) vs 48 +/- 28cm(2), P=non-significant).Conclusion Vertical incision results in shorter scars but may be associated with increased incidence of haematomas. Meticulous closure of the subcutaneous tissue is recommended.
