Abstract
Background. Orthopedic hardware infections often require hardware removal or replacement. In some situations, hardware removal is not possible or would require amputation. Thus, a method of in-situ hardware salvage could significantly improve patient outcomes. Hypochlorous acid is a broad-spectrum antimicrobial solution with rapid effectiveness in biofilm impairment.
Methods. This article presents 2 patients with orthopedic hardware infection. Patient A had recurrent draining sinuses from an intramedullary nail in the femur. The orthopedic surgery team recommended above-knee amputation if hardware salvage was not possible. Patient B had a degloving injury of the right upper extremity with radius and ulna fractures that required revascularization and free flap coverage; when hardware infection developed, hardware removal would have required external fixator placement. In both patients, hypochlorous acid was used intraoperatively during debridement to soak the hardware for 5 minutes. Closed suction drains were placed along the hardware, and postoperative instillations of hypochlorous acid were placed through the drains for 5 minutes 1 to 2 times a day for 4 days for Patient A and 7 days for Patient
Results. On follow-up at 10 months for Patient A and at 9 months for Patient B, there was no evidence of recurrent hardware infection. Hardware was successfully salvaged in both patients.
Conclusions. Hypochlorous acid is an effective and safe topical antimicrobial agent for recurrent infections due to hardware-associated biofilm. Postoperative instillations of 0.025% hypochlorous acid through closed suctions drains may improve hardware salvage rates and optimize

Abstract: Cutaneous wound healing consists of four stages: hemostasis, inflammation, proliferation/repair, and remodeling. While healthy wounds normally heal in four to six weeks, a variety of underlying medical conditions can impair the progression through the stages of wound healing, resulting in the development of chronic, non-healing wounds. Great progress has been made in developing wound dressings and improving surgical techniques, yet challenges remain in finding effective therapeutics that directly promote healing. This review examines the current understanding of the pro-healing effects of targeted pharmaceuticals, re-purposed drugs, natural products, and cell-based therapies on the various cell types present in normal and chronic wounds. Overall, despite several promising studies, there remains only one therapeutic approved by the United States Food and Drug Administration (FDA), Becaplermin, shown to significantly improve wound closure in the clinic. This highlights the need for new approaches aimed at understanding and targeting the underlying mechanisms impeding wound closure and moving the field from the management of chronic wounds towards resolving wounds.
