A Sensor-Based Decision Support System for Transfemoral Socket Rectification.

Sensors (Basel) 2021 May 28;21(11). Epub 2021 May 28.

TWI-Hellas, 152 32 Halandri, Greece.

A decision support system (DSS) was developed that outputs suggestions for socket-rectification actions to the prosthetist, aiming at improving the fitness of transfemoral prosthetic socket design and reducing the time needed for the final socket design. For this purpose, the DSS employs a fuzzy-logic inference engine (IE) which combines a set of rectification rules with pressure measurements generated by sensors embedded in the socket, for deciding the rectification actions. The latter is then processed by an algorithm that receives, manipulates and modifies a 3D digital socket model as a triangle mesh formatted inside an STL file. Read More

Harnessing Digital Health Technologies to Remotely Manage Diabetic Foot Syndrome: A Narrative Review.

Medicina (Kaunas) 2021 Apr 14;57(4). Epub 2021 Apr 14.

Interdisciplinary Consortium on Advanced Motion Performance (iCAMP), Michael E. DeBakey Department of Surgery, Baylor College of Medicine, Houston, TX 77030, USA.

About 422 million people worldwide have diabetes and approximately one-third of them have a major risk factor for diabetic foot ulcers, including poor sensation in their feet from peripheral neuropathy and/or poor perfusion to their feet from peripheral artery disease. The current healthcare ecosystem, which is centered on the treatment of established foot disease, often fails to adequately control key reversible risk factors to prevent diabetic foot ulcers leading to unacceptable high foot disease amputation rate, 40% recurrence of ulcers rate in the first year, and high hospital admissions. Thus, the latest diabetic foot ulcer guidelines emphasize that a paradigm shift in research priority from siloed hospital treatments to innovative integrated community prevention is now critical to address the high diabetic foot ulcer burden.

Replantation of amputation at the wrist: challenges of management in sub-Saharan Africa.

BMJ Case Rep 2021 Mar 2;14(3). Epub 2021 Mar 2.

Department of Surgery, University of PortHarcourt, PortHarcourt, Rivers State, Nigeria.

Amputations of the upper limb, in particular, have a major impact on patients' lives, as loss of function can not only cause reduced autonomy in daily life but also hinder social interactions and capacity for work. Replantation at or proximal to the wrist, referred to as wrist-proximal replantation, remains a daunting challenge that presents the hand surgeon with an array of difficulties distinct from digital replantation.We present our experience with a successful replantation of a near-complete amputation at the non-dominant left wrist in a 25-year-old man managed in sub-Saharan Africa.

What Is the Survival of the Telescope Allograft Technique to Augment a Short Proximal Femur Segment in Children After Resection and Distal Femur Endoprosthesis Reconstruction for a Bone Sarcoma?

Clin Orthop Relat Res 2021 Feb 26. Epub 2021 Feb 26.

S. Hindiskere, Department of Musculoskeletal Oncology, HCG Hospital, Bangalore, India.

Background: Large, malignant bone tumors and revision limb salvage procedures often result in the resection of extensive lengths of the involved bone segment, leaving a residual segment of bone that may be too short to support a standard intramedullary stem for endoprosthetic reconstruction. Telescope allografting, in which an allograft is used to augment the remaining bone segment by telescoping it into the residual bone segment, was described for situations in which residual bone stock is insufficient after tumor resection or prosthetic revision. Apart from one study that first described the procedure [15], there are no other studies reporting the outcome of this telescopic concept for restoring bone stock. Read More
