Purpose: After harvesting a radial forearm flap (RFF) an optimal aesthetic and functional restitution of the donor site is required. In order to cover the secondary defect of the donor site, several solutions are currently available, but there is still no real evidence of the most reliable option. A retrospective study was conducted in order to evaluate a new technique of forearm coverage with artificial dermis: the association of full thickness skin graft (FTSG) with Matriderm®.
Methods: Our study included all RFF performed during a 34-month period. Forty-three forearm secondary defects after harvesting a RFF (16 men, 27 female) were included. Forearm donor site was covered using three techniques: a simple FTSG, split thickness skin graft (STSG) with Matriderm® or FTSG with Matriderm®. Clinical evaluations based on residual functionality, skin quality and aesthetic result were assessed using respectively the Disabilities of the Arm, Shoulder and Hand (DASH) score, the Vancouver Scar Scale (VSS) score and a blind panel questionnaire.
Results: FTSG with Matriderm® showed an improved DASH (10.6/100) and VSS score (5.5/13) if compared to the other techniques, mean surgeon satisfaction score was 3/5, mean patient satisfaction score was 3/5 in the FTSG with Matriderm® group.
Conclusion: The results of this study revealed that the new association of FTSG with Matriderm® improves the DASH score and the aesthetic outcomes resulting to be a reliable solution in treating full thickness forearm skin defects after RFF harvesting.

Purpose Of The Study: The aim of this study to evaluate the subjective and objective results of Extensor indicis proprius (EIP) to extensor pollicis longus (EPL) transfer with an emphasis on donor site morbidity.
Material And Methods: 17 patients (59% men, 41% women) who underwent EIP-EPL transfer were retrospectively analyzed. The mean age was 43 (9-64) years, and the mean follow-up was 72 (19-124) months.

In acute myeloid leukemia (AML), leukemogenesis depends on cell-intrinsic genetic aberrations and thus, studies on AML require investigations in an in vivo setting as provided by patient derived xenografts (PDX) models. Here we report that, next to leukemic cell characteristics, recipient sex highly influences the outgrowth of AML cells in PDX models, with females being much better repopulated than males in primary as well as secondary transplantation assays. Testosterone may be the more important player since, strikingly, better engraftment was seen in castrated versus control male recipients, while ovariectomy did not significantly impair engraftment in females.

Mosaicplasty is a relatively challenging procedure used in the management of focal osteochondral lesions of the joints. Donor-site morbidity is still the main concern after mosaicplasty because it entails the harvesting of an osteochondral autograft from an otherwise healthy region to be impacted later on the weight-bearing damaged site. We describe a possible alternative to conventional mosaicplasty with subchondral bone support harvested from the iliac crest as an osteoperiosteal autograft and covered with a minced cartilage layer.

Anterior cruciate ligament reconstruction with quadriceps tendon autograft has become increasingly popular for primary and revision anterior cruciate ligament reconstruction surgery. Although there are a variety of techniques available for performing quadriceps tendon autograft harvest for anterior cruciate ligament reconstruction, a minimally invasive, all-soft tissue harvest technique can result in a reproducible, reliable graft while minimizing donor-site morbidity. In this Technical Note, we describe our preferred technique for quadriceps tendon autograft harvest for anterior cruciate ligament reconstruction.

Skin grafting techniques are widely used for large burns, trauma, and various acute and chronic wounds, contributing greatly to the repair of traumatic tissue. However, donor site repair and regeneration are often neglected, resulting in infection and delayed healing. Therefore, it is crucial to reduce the rate of donor site infection and improve the speed and quality of healing.
