Negative Pressure Wound Therapy Combined With Instillation for Sternoclavicular Joint Infection.

BACKGROUND

There is no consensus on the management of spontaneous sternoclavicular joint infection (SCJI). Negative pressure wound therapy (NPWT) has been widely accepted for SCJI. We reviewed our experience with the management of this condition comparing NPWT alone and NPWT combined with instillation and dwell time.

METHODS

We retrospectively analyzed the data of patients with spontaneous SCJI treated in our thoracic unit.

RESULTS

From March 2008 to October 2019, 27 patients (21 men and 6 women) underwent NPWT combined with muscle flap transfer after necrosectomy and chest wall resection for SCJI. The median age was 57.1 years (range, 35 to 85). Depending on management, the patients were divided into two groups: 16 patients with NPWT in group 1, and 11 patients with NPWT combined with instillation and dwell time in group 2. The severity of SCJI, extent of chest wall resection, and type of muscle flap were not significantly different (P = .35, P = .858, P = .705, respectively). Median duration of hospital stay and NPWT were shorter in group 2 (30 vs 25 days, and 20 vs 16 days, respectively). The required wound dressing changes were significantly lower in group 2 (P = .008). Statistical trend to higher bacterial eradication in group 2 was noted (P = .093). Postoperative complications including SCJI recurrence, wound seroma, and dehiscence were not significantly different between groups (P = .269).

CONCLUSIONS

The NPWT combined with instillation and dwell time appears a useful strategy in patients with SCJI, leading to higher incidence of bacterial eradication and shorter wound care.
