Both mountain pine beetle (MPB) Dendroctonus ponderosae Hopkins and fire leave scars with similar appearance on lodgepole pine Pinus contorta Dougl. ex Loud. var. latifolia Engelm. that have never been compared microscopically, despite the pressing need to determine the respective effects of MPB and fire injury on tree physiology. We analysed changes in wood formation in naturally caused scars on lodgepole pine, and tested the hypotheses that (i) MPB and fire injury elicit distinct anomalies in lodgepole pine wood and (ii) anomalies differ in magnitude and/or duration between MPB and fire...

The fasciocutaneous lateral arm flap is a workhorse flap in upper extremity reconstruction. However, its adipofascial variant is not widely used. The technique can be used in various clinical scenarios. The adipofascial flap can be transposed to circumferentially wrap the radial nerve with a pliable, vascularized fat and fascial envelope, mimicking the natural fatty environment of peripheral nerves. This technique has the advantage of providing a scar tissue barrier, a barrier to hardware irritation and a milieu for vascular regeneration of the nerve...

OBJECTIVE: The purposes of this article are to place the controversy over the management of radial scars diagnosed at core biopsy in perspective and to define reasonable management options. CONCLUSION: The management of radial scars after image-guided core biopsy of the breast for diagnosis remains controversial. Although current literature suggests no premalignant potential of these lesions, it does not fully explain the small but real percentage of these lesions that are upgraded to malignancy after surgical excision...

Loco-regional flaps have been widely used for the reconstruction of digital injuries without requiring microvascular anastomosis, however, they result in scarring and compromised functional outcomes. This study demonstrates our experience utilizing the innervated radial artery superficial palmar branch (RASPB) perforator free flap for complex digital injury reconstruction. From May 2007 to March 2014, the innervated RASPB perforator free flap was used to reconstruct 79 distal complex hand and digital soft tissue defects of which 14 were used to re-vascularise the distal digit in a flow-through fashion...

Phalloplasty is indicated in various conditions of penile loss or absence. There are numerous techniques for phalloplasty including the pedicle and free flaps with the ultimate goal of micturition in standing position, attaining adequate size, aesthesis and sensations for sexual intercourse. Radial forearm phalloplasty is the gold standard flap to achieve above results but gives a very bad scar on the forearm. We present a technique of using prefabricated thigh flap to reduce the morbidity of donor area. The descending branch of lateral circumflex femoral pedicle was placed in a subcutaneous plane over tissue expander...

INTRODUCTION: Traditional open reduction and internal fixation (ORIF) of extra-articular distal humerus fractures has a risk of iatrogenic radial nerve injury, extensive soft tissue stripping, and long incision scar. We performed an antero-lateral minimally invasive plate osteosynthesis (MIPO) technique with the radial nerve exploration for distal-third diaphyseal fractures of the humerus and evaluated clinical and radiographic outcomes through this respective study. METHODS: From April 2010 to June 2016, 28 cases of extra-articular distal-third diaphyseal fractures were treated with an antero-lateral MIPO procedure...

BACKGROUND: The region between the proximal interphalangeal (PIP) and the metacarpophalangeal (MP) creases has greater laxity than other regions in the fingers, allowing for primary closure of the donor site. We postulated if we could consistently locate perforators from the region between the PIP and the MP crease on the radial side of the middle and ring fingers, on which a scar would be less conspicuous than one on the radial side of the index finger, these regions would be ideal donor sites for digital reconstruction using very small flaps...

INTRODUCTION: Radial forearm free flap (RFFF) tube-in-tube phalloplasty is the most performed phalloplasty technique worldwide. The conspicuous donor-site scar is a drawback for some transgender men. In search for techniques with less conspicuous donor-sites, we performed a series of one-stage pedicled anterolateral thigh flap (ALT) phalloplasties combined with RFFF urethral reconstruction. In this study, we aim to describe this technique and assess its surgical outcome in a series of transgender men...
