REVIEW
Durga Karki, Rajeev B Ahuja
Contractures of the axilla and elbow can produce a significant impact on quality of life by reducing the ability to perform activities of daily living. Varieties of techniques are available for resurfacing defects following contracture release but graft or flap loss, donor-site morbidity, esthetics, and recurrences are still challenges for reconstructive surgeons. Central axis "propeller" flaps based on a random, subcutaneous pedicle were first described for axillary and elbow contractures to deploy the unburnt skin of axillary dome in type I and II contractures (Kurtzman and Stern) by moving them 90° to straddle the contracting bands...

BACKGROUND: The reconstruction of the posterior trunk, especially with large dead spaces, remains challenging. Regional muscle flaps may lack adequate volume and reach. The purpose of this report was to evaluate the efficacy of deepithelialized free-style perforator-based propeller flaps to obliterate defects with large dead space. METHODS: A total of 7 patients with defects on the posterior trunk with large dead spaces were evaluated. After complete debridement or resection, all flaps were designed on a single perforator adjacent to the defect, deepithelialized, and then rotated in a propeller fashion...

Honey bees (Apis mellifera) are remarkable fliers that regularly carry heavy loads of nectar and pollen, supported by a flight system - the wings, thorax and flight muscles - that one might assume is optimized for aerial locomotion. However, honey bees also use this system to perform other crucial tasks that are unrelated to flight. When ventilating the nest, bees grip the surface of the comb or nest entrance and fan their wings to drive airflow through the nest, and a similar wing-fanning behavior is used to disperse volatile pheromones from the Nasonov gland...

Novel and combined tissue transfers from the lower extremity provide new tools to combat soft tissue defects of the hand, foot, and ankle, or fracture nonunion. Flaps can be designed for special purposes, such as providing a gliding bed for a grafted or repaired tendon or for thumb or finger reconstruction. Propeller flaps can cover soft tissue defects of the leg and foot. In repairing severe bone and soft tissue defects of the lower extremity, combined approaches, including external fixators, one-stage vascularized bone grafting, and skin or muscle flap coverage of the traumatized leg and foot, have become popular...

INTRODUCTION: In lower limbs, reliability of propeller perforator flaps (PPF) remains uncertain. The main complication is venous congestion, which can lead to distal necrosis. We aim to highlight if venous supercharging of PPF could substantially limit complications in lower limb coverage. METHODS: Between 2011 and 2016, we developed a standardized procedure of venous supercharging in the lower limb reconstruction with PPF using saphenous veins anastomosis. Then, we prospectively compared a consecutive series of 30 PPF to cover lower limbs defect, with a consecutive series of 30 venous-supercharged PPF (vsPPF)...

Reconstruction of large myelomeningocele defects using extended (elongated beyond the lateral margin of the latissimus dorsi muscle) dorsal intercostal artery perforator (DICAP) propeller flaps is not recommended by previous studies. However, to provide tension-free and successful closure of a defect, the DICAP propeller flaps must sometimes be elongated beyond this margin. Our experience and results in this issue are discussed. In this article, reconstruction of 11 consecutive cases, with large myelomeningocele defects in which standard DICAP propeller flaps were incapable to close the defect, was achieved using extended DICAP propeller flaps between June 2013 and November 2015...

The majority of surgical burn care involves the use of skin grafts. However, there are cases when flaps are required or provide superior outcomes both in the acute setting and for postburn reconstruction. Rarely discussed in the context of burn care, the perforator-based propeller flap is an important option to consider. We describe our experience with perforator-based propeller flaps in the acute and reconstructive phases of burn care. We reviewed demographics, indications, operative details, and outcomes for patients whose burn care included the use of a perforator-based propeller flap at our institution from May 2007 to April 2015...

Current data on upper extremity propeller flaps are poor and do not allow the assessment of the safety of this technique. A systematic literature review was conducted searching PubMed, EMBASE, and the Cochrane Library electronic databases, and the selection process was adapted from the preferred reporting items for systematic reviews and meta-analysis statement. The final analysis included ten relevant articles involving 117 flaps. The majority of flaps were used for the hand, distal wrist, and elbow. The radial artery perforator and ulnar artery perforator were the most frequently used flaps...

The versatility of fish to adapt to different swimming requirements is attributed to their complex muscular system. Fish modulate their fin stiffness and shape for maximized performance. In this paper, optimal chordwise stiffness profiles that maximize the propulsive performance have been predicted using theoretical studies. An experimental setup has been fabricated to measure the stiffness profiles of real fish caudal fins. Chordwise varying stiffness robotic fins fabricated using carbon fiber reinforced composites (CFRC) have been tested in the water tunnel to evaluate their performance over constant stiffness fins...
