BACKGROUND: With an aging but still active population, open ankle fractures are increasingly presenting as low energy fragility injuries, sharing many characteristics with that of hip fractures. Yet, there is little in the literature on the management and outcome of these fractures. The primary aim of this study was to describe the outcome following open, ankle fragility fracture. Our secondary aim was to identify potential factors that improved outcome. METHODS: All consecutive, low energy open ankle fractures treated at a Level I Trauma Centre over a five-year period were included...

Initial treatment of damaged tendons after soft tissue trauma of the hand can be performed with primary tendon reconstruction or with tendon grafts if indicated. The most frequently used tendons are from the palmaris longus and plantaris muscles. Nonetheless, these muscles may not be present or their anatomic characteristics might not suitable for reconstructive procedures. Here, we present an alternative surgical technique for tendon reconstruction of the hand using abductor pollicis longus accessory tendons as grafts...

INTRODUCTION: Myeloid Sarcoma (MS) is a rare hematologic myeloid neoplasm that can involve any site of the body. It can occur as an exclusively extramedullary form or it can be associated with an acute myeloid leukemia (AML), a chronic myeloproliferative neoplasm (MPN) or a myelodysplastic syndrome (MDS) at onset or at relapse. The rarity of MS does not enable prospective clinical trials and therefore a specific multicenter register can be useful for the clinical and biological studies of this rare disease...

Traumatic nail bed injuries to the hand are a common problem for hand surgeons. Whereas the majority of those are treated with primary repair, the remainder present significant surgical challenges to address residual soft tissue defects. In this article, we present our approach to treating injuries to the fingertips utilizing single-layer bovine acellular dermal matrix grafts.

BACKGROUND: Autologous fat grafting is a widely used technique that gives natural results when treating soft tissue deficiencies. However, there is no consensus on which is the best procedure to use, leading to unpredictable results because of fat graft resorption. OBJECTIVES: This study compared four commercial lipotransfer devices by analyzing the behavior of the processed adipose tissue and outcome of the adipose graft in an in vivo model. METHODS: Four different protocols that used manual, power-assisted or water-assisted lipoaspiration and then decantation, centrifugation, or filtration were used on each of eight patients to process lipoaspirate...

INTRODUCTION: Latest advances made in joint replacement implants allows reconstruction of entire limbs. These special prostheses or megaprostheses were originally designed for the treatment of severe oncological bone loss. Nowadays, however, the indications and applications of these devices are expanding to other orthopaedic and trauma clinical conditions. Since 2008 we have implanted 152 megaprostheses in non-oncological conditions: 87 were implanted for post-traumatic failures aseptic/septic (represented by complex non-unions and critical size bone defects); 26 total femur, 52 distal femur and 9 proximal tibia...

Vascular grafts made by tissue engineering processes are prone to buckling and twisting, which can impede blood flow and lead to collapse of the vessel. These vascular conduits may suffer not only from insufficient tensile strength, but also from vulnerabilities related to compression, torsion, and pulsatile pressurization. Aiming to develop a tissue engineering-inspired blood conduit, composite vascular graft (cVG) prototypes were created by combining a flexible polylactic acid (PLA) knitted fabric with a soft polycaprolactone (PCL) matrix...

To our knowledge, the imaging features of costochondral grafts (CCGs) on cone-beam computed tomography (CBCT) have not been documented in the literature. We present the case of a CCG in the facial soft tissue to the anterior mandible, with changes mimicking a cartilaginous neoplasm. This is the first report to describe the CBCT imaging features of a long-standing graft in the anterior mandible. Implants or grafts may be incidental findings on radiographic images made for unrelated purposes. Although most are well-defined and radiographically homogeneous, being of relatively inert non-biological material, immune reactions to some grafts may stimulate alterations in the appearance of surrounding tissues...

Recent advantages in the anatomical understanding of the face have turned the focus toward the subcutaneous and deep facial fat compartments. During facial aging, these fat-filled compartments undergo substantial changes along with other structures in the face. Soft tissue filler and fat grafting are valid methods to fight the signs of facial aging, but little is known about their precise effect on the facial fat. This narrative review summarizes the current knowledge about the facial fat compartments in terms of anatomical location, histologic appearance, immune-histochemical characteristics, cellular interactions, and therapeutic options...

One of the characteristics of mestizo patients can be the thick sebaceous skin associated with a poor osteocartilaginous underlying nasal structure. In spite of using a proper structural approach where grafts and sutures are used to define the nasal tip, frequently the results are suboptimal. Surgical techniques have been described to reduce the thickness of the skin-soft tissue envelope, but these frequently give unreliable results. The monitored use of isotretinoin given orally as a complement after performing a rhinoplasty can adequately control the production of the sebaceous glands and thin the skin-subcutaneous tissue envelope in a uniform fashion without compromising the underlying bony and cartilaginous structures of the nose...

The alar lobule, alar margin, and soft triangle facet are receiving more attention in the literature as critical elements to address both preoperatively and during rhinoplasty. We have found that the use of the articulated alar rim graft (AARG) corrects deficiencies in these areas as well as provides mechanical stability to the external valve. In this article, we describe indications for AARG, describe in detail the procedure for AARG placement, and highlight the transformation AARGs can achieve in two illustrated case studies...

BACKGROUND: Advances in staged total auricular reconstruction have resulted in improved anterior auricular appearance; however, satisfactory postreconstruction esthetics of the retroauricular fold remain challenging. The postauricular appearance of the reconstructed ear depends largely upon optimizing the covering material. When used as the covering soft tissue for ear elevation, a flap containing primarily the upper portion of the retroauricular fascia has potential advantages over the conventional book cover-type retroauricular fascia flap...
