Ischemic limbs with infected heel ulcers are often difficult to salvage. We present a case of an 82-year-old woman who had bilateral heel ulcers owing to chronic limb-threatening ischemia. She underwent right femoral-terminal posterior tibial artery bypass surgery, but right calcaneus osteomyelitis occurred and inhibited wound healing. She underwent partial calcanectomy (PC), and her right heel healed six months after the bypass surgery. The ulcer on her left foot also healed after distal bypass and PC. We describe our experience with a patient who needed PC to cure her heel ulcers.

The finite-element method (FEM) is a well-established procedure for computing approximate solutions to deterministic engineering problems described by partial differential equations. FEM produces discrete approximations of the solution with a discretisation error that can be quantified with a posteriori error estimates. The practical relevance of error estimates for biomechanics problems, especially for soft tissue where the response is governed by large strains, is rarely addressed.

Purpose: The aim of this study was to propose a lateral oscillating device for the prevention of pressure ulcers by understanding the mechanisms of tissue protection in healthy individuals during prolonged decubitus. We also sought to determine the optimal time interval for oscillation, considering peak pressure peaks and tolerable pressure limits as a function of individual characteristics such as age, weight, height, gender, and BMI.
Methods: A quasi-experimental, descriptive and analytical observational study was conducted between January 2022 and June 2023 with a sample of 25 healthy volunteers.

: Pressure injuries are localized areas of tissue damage or necrosis that occur when pressure is applied to the skin for prolonged periods, often over bony prominences, often the sacrum, heels, ischial tuberosities, and greater trochanters. The pathophysiology is complex, involving a combination of mechanical forces, ischemia, and tissue hypoxia. : We conducted a 2-year retrospective study aiming to assess the clinical characteristics, risk factors, and management of pressure injuries in patients admitted to an emergency hospital who underwent a plastic surgery examination.

Hard-to-heal wounds represent a global and growing medical and economic burden. Skin autografting is a useful treatment option but is often limited by donor site morbidity, logistical considerations, and grafting success in compromised wound beds. Combining autologous skin cell suspension (ASCS) technology with minced dermal grafts can allow for dermal elements and epithelial healing as well as closed donor sites.
