Distal profunda femoris artery perforator island flap for distal thigh and knee reconstruction: a CT-based anatomical analysis and a case-series study.

Background: Locoregional flap options for reconstructing defects of the anterolateral distal thigh/knee region are limited. The distal profunda artery perforator island (PAPI) flap is a local fasciocutaneous propeller-type flap that utilizes the most distal perforator of the profunda femoris artery. The aim of this study is to conduct a CT-based angiographic analysis of the perforator system of the profunda femoris artery and present outcomes on the application of the PAPI flap in the management of post-oncologic defects of the distal thigh and knee.

The Lymphatic Response to Injury with Soft-Tissue Reconstruction in High-Energy Open Tibial Fractures of the Lower Extremity.

Background: Severe compound tibial fractures are associated with extensive soft-tissue damage, resulting in disruption of lymphatic pathways that leave the patient at risk of developing chronic lymphedema. There are limited data on lymphatic response following lower limb trauma. Indocyanine green fluorescence lymphography is a novel, real-time imaging technique for superficial lymphatic mapping.

Fibro-Osseous Pseudotumour of the Digit: An Illustrative Case and Review of the Literature.

Fibro-osseous pseudotumour is a rare, benign ossifying tumour of soft tissue that should be considered in the differential diagnosis of any tumour affecting the digits. Clinical diagnosis is difficult and fibro-osseous pseudotumour is often mistaken for malignancy, leading to inappropriate treatment. Knowledge of its clinical and histopathological features thus allows for appropriate primary treatment, sparing the patient from unnecessary radical surgery associated with presumed malignancy.

A biodegradable polyurethane dermal matrix in reconstruction of free flap donor sites: a pilot study.

We have developed a biodegradable temporizing matrix (BTM) capable of supporting secondary split-skin graft-take in animal studies. We report its first long-term implantation and use as a dermal scaffold in humans. This preliminary study assesses its ability to integrate, its ease of delamination, its ability to sustain split-skin graft in complex wounds, the degree of wound contraction, and ultimately the quality of the scar at 1 year postimplantation.

The Deep Inferior Epigastric Perforator Learning Curve in the Current Era.

Background: Over the last 2 decades, the deep inferior epigastric perforator (DIEP) flap has gained significant popularity in breast reconstruction. However, for some, the increased technical difficulties associated with DIEP breast reconstruction can be a discouraging factor in adopting this technique. There has been a trend in the literature to acknowledge an acute learning curve in the adoption of DIEP breast reconstruction but little evidence to support its ongoing relevance to surgeons who gain significant exposure in training.
