Use of an Occlusive Skin Closure System May Reduce Post-operative Wound Drainage After Tumor Arthroplasty of the Hip

Background:

Patients undergoing bone tumor resection and subsequent endoprosthetic reconstruction are at significant risk of developing prosthetic joint infection (PJI)Additionally, numerous factors contribute to a significant predisposition of these patients to wound healing complications, including the burden of their primary disease, associated comorbidities, previous or ongoing treatment often involving chemotherapy and or radiotherapy, and the extent of the necessary surgical procedure. In a retrospective review of this specific patient population treated at the investigators institution during recent years, the investigators have found a very high prevalence of persistent discharge from the surgical wound, when routine wound closure with skin staples was used. This is of particular concern, as an association of this post-operative complication with a higher incidence of PJI has been clearly established in several large studies on conventional total hip arthroplasty. Another previous study showed that prolonged wound discharge (PWD) will often lead to increased length of hospital stay and increased use of antibiotics to prevent infection. In the same study, the investigators were able to demonstrate a substantial reduction of PWD, use of intra-venous antibiotics and length of hospital stay, with use of an alternative skin closure method, combining intradermal suture and Steristrips for optimal wound edge apposition and a topical skin adhesive (2-octyl cyanoacrylate) as a sealant. However, more extensive data on the prevalence of persistent surgical wound discharge and the preventive effect of skin adhesives as an adjunct to wound closure in high-risk patient populations are lacking in the literature.

Investigational Product:

The DERMABOND PRINEO Skin Closure System has been specifically developed with the goal to achieve fast and secure closure of long incisions. It consists of two components, a pressure sensitive adhesive (PSA) initiated flexible mesh, designed for wound edge approximation and a cyanoacrylate based topical skin adhesive for occlusive wound closure. Intradermal suture is not necessary, as this system has been shown to support wound closure strength equivalent to subcuticular 3-0 sutures and is able to provide even distribution of tension across the entire incision length to ensure wound edge approximation throughout the wound healing process. Furthermore, compared to subcuticular suture, it has demonstrated equivalent wound healing and cosmesis at 90 days, while reducing wound closure time by up to 70%. It also provides an immediately effective occlusive barrier with documented antimicrobial properties, enabling patients to shower directly following a procedure and can be easily removed after the patient's natural wound healing process is complete, estimated at anywhere between 12 to 25 days.
