Wound healing of open fractures: comparison of vaccum assisted dressing versus traditonal dressing.

PURPOSE: For permanent wound coverage of compound fractures, the wound surface should have 100% granulation tissue without any discharge or necrotic slough. Negative pressure wound therapy (NPWT) is a well known modality in the management of open fractures, and post-operative wound problems. This study was conducted to compare the outcome of NPWT and traditional dressing in wound healing of open fractures. MATERIAL AND METHODS: A prospective study of 100 cases was conducted to compare the wound healing outcomes of open fracture following vacuum assisted closure (VAC) dressing (50 cases) and traditional wound dressing (50 cases). Patients included in the study underwent initial debridement to remove necrotic slough and tissue when indicated. Foam dressings were used to cover the wounds using aseptic conditions in the VAC group. Dressings were changed daily for patients in traditional dressing group using hydrogen peroxide, normal saline and povidone iodine in a sequential manner and every 3-4 days in the VAC dressing group. Patients were evaluated clinically for appearance of granulation tissue, duration of hospital stay and reduction in wound surface area using appropriate statistical methods. RESULT: There was a significant difference between the rate of wound healing in the group NPWT/VAC group compared to the traditional wound dressings group in terms of appearance of granulation tissue, reduction in wound surface area and duration of hospital stay. CONCLUSION: Vacuum assisted dressing is more effective than traditional wound dressing in wound healing of open fractures.

Broken Pieces of Circlage Wire Lying in Soft Tissue Envelope Around Knee Joint: A Case Report and Review of Literature.

INTRODUCTION: The migration of circlage wires used in tension band wiring construct of patella fractures in the posterior soft tissue envelope surrounding the knee joint has been rarely reported. CASE PRESENTATION: A 60-year-old woman presented to us with pain over medial aspect of right knee joint. She underwent open reduction and internal fixation for a patellar fracture which she sustained 4 years back and subsequently underwent kirschner wire(k wire) removal for the same around 2 years back. X-rays of the knee joint shows that the circlage wire used in tension band construct which was left in place had broken into multiple pieces and was lying in the soft tissue envelope surrounding the knee joint and one piece migrate to the popliteal fossa. On examination patient did not had distal neuro-vascular deficit. The pain of the patient was due to the osteo-arthritic changes in her medial side of knee joint rather than broken wire pieces. Patient was advised to undergo total knee replacement along with subsequent removal of broken wires but patient refused for any type of surgery and is kept on regular follow up. CONCLUSION: This case report summarizes a rare complication resulting from hardware failure used for fixing patella fractures and throws a light on potential unwarned complications due to broken wires along with early recogonition and removal of broken hardware by surgeons.
