Advances in Soft Tissue Injuries Associated with Open Fractures

Management of soft tissue injury is a key component in the overall treatment of upper extremity fractures. Hand surgeons must rely on their armamentarium for treating soft tissue deficits for functional outcomes. Understanding the role of fracture fixation and wound adjuncts, including negative pressure wound therapy and dermal regenerative templates, is the keys to success. In addition, detailed knowledge of local and free tissue options is essential for hand reconstruction.

Pulsatile lavage systems and their potential to penetrate soft tissue

BACKGROUND

In orthopedic and trauma surgery, pulsatile lavage systems are used to clean soft tissue. This may be necessary in septic surgeries or in case of contaminated wounds after trauma. Positive features such as reduction of bacterial contamination and removal of foreign particles are counterbalanced by negative aspects such as bacterial seeding in deeper tissue layers, damage to various tissues and even cases of air embolism.

PURPOSE

The aim of this prospective experimental in vitro study was to compare impact pressure and flow rate in three different pulsatile lavage systems and to determine, whether these parameters alter their ability to reach deeper soft tissue layers.

METHODS

To test the penetration of soft tissue, the muscle tissue was flushed with contrast medium instead of saline fluid and afterwards scanned by computed tomography.

RESULTS

Impact pressure and flow rate showed significant differences between the different systems. There were no significant differences between the three devices in terms of total penetration volume, but there were significant differences in penetration depth.

CONCLUSION

In this study, we found that higher impact pressure leads to deeper penetration and therefore bacteria are likely to be transferred to deeper tissue layers.

Outcomes of topical phenytoin in the management of traumatic wounds

INTRODUCTION

Regular dressing of traumatic wounds is of paramount importance for healing. Phenytoin, an anticonvulsant, is thought to promote wound healing through multiple mechanisms, including fibroblast proliferation, granulation tissue formation, antibacterial activity, and pain alleviation.

AIM

To assess the effect of topical phenytoin on traumatic wound healing in terms of granulation tissue formation, pain alleviation, and time taken for wound healing.

METHODOLOGY

Fifty patients with traumatic wounds were divided into equal and comparable groups. After cleaning the wound, phenytoin dressing was done in the study group and saline dressing in the control group. Thereafter, regular dressings of the wounds were done, and healing was assessed on day 14 and day 21.

RESULTS

On day 14, the wound surface area, percentage of granulation tissue, VAS score amongst cases was 39.4 ± 29.75 cm², 82.12 ± 9.71%, 4.52 ± 1.08, and that of controls was and 51.28 ± 25.33 cm², 62.72 ± 9.01%, 6.52 ± 1.22, respectively. On day 21, the wound surface area, percentage of granulation tissue, VAS score amongst cases were 29.4 ± 29.88 cm², 92 ± 4.46%, 2.8 ± 0.94, and that of controls were 38.92 ± 23.24 cm², 78.56 ± 8.19%, and 4.88 ± 1.17, respectively. The time taken for wound healing was 21.76 ± 5.28 days amongst cases and 31.64 ± 8.31 days amongst controls. Staphylococcus aureus was the commonest organism isolated in both the groups. On day 14,18(72%), wounds in the study group showed negative culture, whereas, in the control group, it was negative in 12 (48%) patients. The rate of granulation tissue formation was higher in cases when compared to controls amongst smokers and diabetics. The difference in all these parameters between the groups was statistically significant (P-value <0.05).

DISCUSSION AND CONCLUSION

We observed a considerable increase in granulation tissue formation, pain alleviation, and reduction in time taken for wound healing. Topical phenytoin is a safe, effective, readily available, and frugal agent that can accelerate wound healing through its multimodal action, thus reducing patient morbidity and economic burden.

Randomized controlled clinical trial on the antiseptic efficacy of polihexanide 0.04% on acute traumatic wounds

Prevention of wound infections is a challenge in clinical practice. The aim of this study was to assess the efficacy of polyhexamethylene biguanide (PHMB, polihexanide) 0.04% on acute traumatic wounds. It was a randomized, double-blind, placebo-controlled prospective trial which included 61 patients. The polihexanide group showed a significant decrease in log₁₀ colony-forming units (cfu) (P < 0.001) after 60 min treatment in comparison to baseline cfu, whereas the Ringer solution group did not show a significant change in cfu during 60 min treatment. Treatment of polihexanide 0.04% resulted in a significant reduction of bacterial load in acute traumatic wounds.

Initial Management of Traumatic Wounds

When traumatic wounds are quickly and accurately treated, morbidity and costs can be significantly decreased. Several factors, such as time delay between injury and treatment, the degree of contamination, extension and depth of the wound, and the mechanism of injury, influence the treatment and prognosis and stress the importance of a patient-specific approach. Although all traumatic wounds are contaminated, antibiotic therapy is seldom required if correct wound management is installed.

Management of traumatic wounds in the Emergency Department: position paper from the Academy of Emergency Medicine and Care (AcEMC) and the World Society of Emergency Surgery (WSES)

Traumatic wounds are one of the most common problems leading people to the Emergency Department (ED), accounting for approximately 5,4 % of all the visits, and up to 24 % of all the medical lawsuits. In order to provide a standardized method for wound management in the ED, we have organized a workshop, involving several Italian and European experts. Later, all the discussed statements have been submitted for external validation to a multidisciplinary expert team, based on the so called Delphi method. Eight main statements have been established, each of them comprising different issues, covering the fields of wound classification, infectious risk stratification, tetanus and rabies prophylaxis, wound cleansing, pain management, and suture. Here we present the results of this work, shared by the Academy of Emergency Medicine and Care (AcEMC), and the World Society of Emergency Surgery (WSES).

Value of incisional negative pressure wound therapy in orthopaedic surgery

Soft tissue and wound treatment after orthopaedic interventions (especially after trauma) is still an enormously challenging situation for every surgeon. Since development of negative pressure wound therapy (NPWT), new indications have been consistently added to the original field of application. Recently, NPWT has been applied directly over high-risk closed surgical incisions. Review of the literature indicates that this therapy has shown positive effects on incisions after total ankle replacement or calcaneal fractures, preventing haematoma and wound dehiscence. In those cases reduced swelling, decreased pain and healing time of the wound were seen. Additionally, NPWT applied on incisions after acetabular fractures showed a decreased rate of infection and wound healing problems compared with published infection rates. Even after total hip arthroplasty, incisional NPWT reduced incidence of postoperative seroma and improved wound healing. In patients with tibial plateau, pilon or calcaneus fractures requiring surgical stabilisation after blunt trauma, reduced risk of developing acute and chronic wound dehiscence and infection was observed when using incisional NPWT. To conclude, incisional NPWT can help to reduce risk of delayed wound healing and infection after severe trauma and orthopaedic interventions.
