Management of traumatic soft tissue defects with dermal regeneration template: A prospective study
ABSTRACT Traumatic soft tissue defect is a common issue for the trauma surgeon. The aim of this study was to evaluate the use of a dermal regeneration template (DRT) associated to a split-thickness skin graft (STSG) to cover severe traumatic wounds involving exposure of deep functional structures.
Patients with severe traumatic defects, either open fractures or full-thickness skin wounds involving exposure of tendons without paratenon, bones without periosteum or joints without articular capsule, managed in the authors' trauma centre, were included in a prospective fashion. They were treated by DRT, associated to STSG within a month and followed up to 18 months. The primary outcome was STSG percentage of take at 18 months. The secondary outcomes included complications rate, functional results, scar retraction rate at 18 months and aesthetic results.
A total of 15 patients were included, with 100% follow-up at 18 months. The mean age was 44.3 years, with nine men. Eighty percent of the wounds were located on the lower limb. After 18 months, the mean STSG take rate was 99.3%. Between the placement of the template and the STSG procedure, the reported complications were template unsticking, seroma, local infection and local oedema. There was no reported haematoma. In terms of functional outcome, percentages of patients undergoing rehabilitation from the time of the skin graft until the end of the follow-up decreased from 80% to 20%. There was 8.7% of retraction in length, and an 8.2% retraction in width. The Vancouver Scar Scale score constantly decreased until 2.5 at 18 months. The final functional and aesthetic subjective scores showed the marks to be located above the 'Satisfying' threshold, either by the surgeon or by the patients.
Eighteen months' follow-up demonstrated that DRT reconstruction is a simple, reliable, efficient tool to treat complex traumatic soft tissue defects.

ABSTRACT: The lower extremities of the human body are more commonly known as the human legs, incorporating: the foot, the lower or anatomical leg, the thigh and the hip or gluteal region. The human lower limb plays a simpler role than that of the upper limb. Whereas the arm allows interaction of the surrounding environment, the legs’ primary goals are support and to allow upright ambulation. Essentially, this means that reconstruction of the leg is less complex than that required in restoring functionality of the upper limb. In terms of reconstruction, the primary goals are based on the preservation of life and limb, and the restoration of form and function. This paper aims to review current and past thoughts on reconstruction of the lower limb, discussing in particular the options in terms of soft tissue coverage. This paper does not aim to review the emergency management of open fractures, or the therapy alternatives to chronic wounds or malignancies of the lower limb, but purely assess the requirements that should be reviewed on reconstructing a defect of the lower limb. A summary of flap options are considered, with literature support, in regard to donor and recipient region, particularly as flap coverage is regarded as the cornerstone of soft tissue coverage of the lower limb.The Open Orthopaedics Journal 10/2014; 8(1):423-432.
