Objective: In full-thickness wounds, it is necessary to have an appropriate dermal replacement because dermal tissue does not regenerate into normal dermis after injury. The use of a dermal matrix underneath a skin graft during the healing process provides a scaffold that supports tissue growth, resulting in improvement of cosmesis and functional outcomes. The management of large wounds with deep skin impairment using a combination of dermal matrices has not been exhaustively studied. The objective of this study was to evaluate the results of managing lower limb trauma, with deep skin impairment, by combining the use of dermal matrices in stages.
Method: This was a retrospective study of patients with lower limb trauma managed using a combination of cadaveric skin and Integra Dermal Regeneration Template (IDRT; Integra LifeSciences Corp., US) in stages, followed by an autologous skin graft, in the Hospital Aleman, Buenos Aires, Argentina from 2014-2021. Cosmesis was evaluated with the Vancouver Scar Scale (VSS) and Patient and Observer Scar Assessment Scale (POSAS). Functional outcomes were assessed one year after surgery.
Results: In total, five patients were treated. The average affected body surface area was 11.2%. The average cadaveric skin, IDRT and skin autograft take rates were 98.4%, 98.4% and 99%, respectively. Upon follow-up, six months after surgery, the mean VSS was 3.2 and the mean POSAS was 27.8. After 12 months, the mean VSS was 2.6 and the mean POSAS was 22.6. In addition, no depression of the covered surfaces was observed. All patients recovered full articular function and movement after physical therapy.
Conclusion: All patients presented full wound coverage with satisfactory cosmesis and functional outcomes. The combination of the use of cadaveric skin and IDRT consecutively in the same wound bed provides promising results for the management of lower limb trauma wounds with deep skin impairment.

Of the 1.5 million emergency room visits each year in the United States due to flexor tendon injuries in the hand, over 30-40% result in peritendinous adhesions which can limit range of motion (ROM) and severely impact an individual's quality of life. Adhesions are fibrous scar-like tissues which can form between adjacent tissues in the body in response to injury, inflammation, or during normal healing following surgery.

Background: Clinical understanding of the obturator nerve's cutaneous and motor branches is crucial for performing effective obturator nerve blocks, particularly for procedures involving the thigh and hip. Literature and anatomical references report highly variable patterns of the frequency and cutaneous distribution of obturator nerve innervation.This study examines the frequency and distribution of the cutaneous branch of the anterior ramus of the obturator nerve (cb-ar-ON) and assesses the most effective anatomical sites for nerve blockade.

Background: Reconstruction of composite digital defects presents challenges, as it requires short-pedicled, small flap. In this report, the authors present a new vascularized bone graft based on the inferior medial genicular artery (IMGA) harvested from the proximal medial tibia with overlying skin. The purpose of this study was to investigate the feasibility of this new flap for small composite tissue defects in digits.

Energised fragments from explosions are the most common wounding mechanism in conflicts and terrorist attacks. Skin covers the vast majority of the human body and is therefore the first anatomical component to be penetrated by fragments, however, its resistance to penetration largely has not been taken into account in models of injury. In this study, an experimental model for ballistic testing of skin is established and a suitable skin simulant for studying resistance to penetration is determined.
