Locomotor biomechanics after total sacrectomy: a case report.

Study Design: Biomechanical analysis of locomotion after total sacrectomy in a single patient case.

Objective: To describe the biomechanics of locomotion after successful total sacrectomy and spinopelvic reconstruction.

Summary Of Background Data: Total sacrectomy is a complex surgery that has significant consequences for mobility after surgery due to loss of lower lumbar and sacral innervation to the lower extremities, and the anatomic dissociation of the spine from the pelvis.

Assessment of three-dimensional high-definition visualization technology to perform microvascular anastomosis.

Background And Aim: Traditional visualization techniques in microsurgery require strict positioning in order to maintain the field of visualization. However, static posturing over time may lead to musculoskeletal strain and injury. Three-dimensional high-definition (3DHD) visualization technology may be a useful adjunct to limiting static posturing and improving ergonomics in microsurgery.

Breast reconstruction satisfaction rates at a large county hospital.

Background: It has been previously reported that the indigent patient population is less likely to seek breast reconstruction. It has also been reported that lower income women who do chose to undergo reconstruction are less satisfied with the results. This study assesses the level of breast reconstruction satisfaction in women treated at Los Angeles County Medical Center (LAC).

Determination of a perfusion threshold in experimental perforator flap surgery using indocyanine green angiography.

Indocyanine green (ICG) angiography has been used in the evaluation of flap perfusion but the viability threshold has not been elucidated. In this study, we determined the threshold by comparing perfusion, using ICG imaging (SPY imaging system, LifeCell Corporation), to clinical evidence of nonviability in rat abdominal perforator flaps. Abdominal flaps, based on a single perforator, were elevated and re-inset in Sprague-Dawley rats.

Optimal dose of enoxaparin in critically ill trauma and surgical patients.

Background: Low-molecular-weight heparin is effective for prevention of venous thromboembolism. The efficacy of daily dosing in critically ill patients is unknown.

Methods: Seventeen critically ill patients on 40 mg of enoxaparin subcutaneously daily were studied.

Elective plastic surgical procedures in adolescence.

Adolescent patients are seeking plastic surgery to correct deformities or perceived deformities in increasing numbers. It is essential for the physician to understand the influence of perceived body image irregularity that motivates patients of all ages to request plastic surgery. The increased demand for plastic surgical procedures among young patients is caused partially to increased media exposure to the available procedures offered by plastic surgeons.

Real-time monitoring of keratin 5 expression during burn re-epithelialization.

Background: Keratin is a major protein produced during epithelialization following burn injury and is a useful marker for assessing wound healing. Transgenic mice expressing enhanced green fluorescent protein (EGFP) driven by the keratin 5 (K5) promoter (K5GFP mice) were used to monitor keratin expression, and thus, re-epithelialization of burn wounds.

Materials And Methods: K5GFP transgenic mice were created using conventional techniques, with PCR and Southern blot confirmation of transgene incorporation, followed by selection of the line with the most intense and consistent basal epithelial EGFP expression.
