Lower Extremity Review
Despite the current recommendations that stable Weber B ankle fractures can be treated with functional bracing and weightbearing as tolerated, some reluctance exists among trauma surgeons to follow these recommendations. This paper reports on our institution’s experience in managing these injuries and compare it to the national guidelines.
The development of foot orthotics—both their prescription designs and their manufacturing processes—is continuously evolving as new materials and new manufacturing technologies arise to meet the changing demands of today’s medical and sport performance needs.

Collagen is the most abundant protein in the human body. It acts as a support structure, giving the skin strength and elasticity. Collagen also plays an essential role in wound healing. During the proliferative phase, fibroblasts migrate into wounded tissues and lay down new…

Having performed thousands of bike fits, I now believe that the bicycle’s crank arm length is the most important factor when performing a bike fit. Every other anatomical dimension and joint angle is based upon the length of the crank arms; therefore, this is the first factor to address when performing a bike fit.

Obesity is among today’s most pressing public health concerns and it’s negative impact on the human body—particularly in light of SARS-COV-2 infection, can be devastating. Once gained, losing weight can be difficult, but maintaining weight loss is even more difficult. This author provides evidence-based tips for maintaining lost pounds that you can share with patients and clients.

Some have worried that foot orthoses that shift plantar load may alter the mechanical work of internal structures and change the size of muscle and connective tissues, and actually make them smaller. These authors challenge that notion.

Running-related injuries (RRIs) are a pervasive menace that can interrupt or end the participation of recreational runners in this healthy physical activity. To date, no satisfactory treatment has been developed to prevent RRIs.
COVID-19 outbreak has a profound impact on almost every aspect of life. Universal masking is recommended as a means of source control. Routinely exercising in a safe environment is an important strategy for healthy living during this crisis.
The University of Utah chemical engineering assistant professor Huanan Zhang, PhD, and his team have developed a process that turns ordinary textile made of a cotton/polyester blend into sensors that measure electrical impulses generated from muscle movement.
Researchers from Harvard University’s John A. Paulson School of Engineering and Applied Sciences (SEAS) and Harvard’s Wyss Institute for Biologically Inspired Engineering have developed a new approach in which robotic exosuit assistance can be calibrated to an…
Northwestern University investigators have discovered the molecular signature of a subset of dopaminergic neurons with an increased vulnerability to degeneration. The findings shed light on the mechanisms at play within a small subsection of the brain’s substantia nigra, called the…
Proprioception, which can be defined as the awareness of the mechanical and spatial state of the body and its musculoskeletal parts, is critical to motor actions and contributes to our sense of body ownership. To date, clinical proprioceptive tests have focused on a person’s ability to detect, discriminate, or…

Cardiovasomobility is a novel concept that encompasses the integration of cardiovascular and skeletal muscle function in health and disease with critical modification by physical activity, or lack thereof. Compelling evidence indicates that physical activity improves health while a sedentary, or inactive, lifestyle accelerates cardiovascular and skeletal muscle dysfunction and hastens disease progression.
Patients who used self-adhesive taping (SAT) as treatment for tuberosity fractures of the proximal 5th metatarsal fared just as well as patients who were placed in short-leg casts (SLC) for the same condition, in a recent study from Turkey. Functional outcome was assessed at the time of injury and at 2, 4, 6, and 12 weeks.
Currently defined as “biological substances found naturally in the body that help injuries heal more quickly,” orthobiologics come in many flavors (see Table). With post-traumatic osteoarthritis and tendinitis dominating the orthopedic care space, use of orthobiologics is getting a lot of attention, but raising a lot of questions as well.
