Hamstring: Trends in preventing and treating hamstring-strain injuries

High relapse rate from preseason injuries presents significant challenge for athletes and sports teams. Hamstring strain injuries are among the most common in sports, often leading to recurring problems or future injury. Marcus Elliott, director of P3 Applied Sports Science and a former muscle-injury specialist for the National Football League’s New England Patriots, conducted…

In a perfect world, no one would need health insurance

In my podiatric practice, I have found that health insurance can impede patient care, by adding layers of complication and burden to all involved, particularly the patient and the provider. Private-sector insurance companies have profits to make, buildings to build, shareholders to satisfy, and overhead costs to pay. Government-run plans have costs, exclusionary policies, bureaucratic oversight, and a changing landscape as administrations change.

Biofeedback aids in resolving the paradox of weight-bearing

Too much? Or not enough? New biofeedback tools help patients with lower-limb fracture in their struggle to understand how much weight to bear on an injured limb. Clinicians whose patients have a lower-limb fracture are faced with a paradox: whether or not to instruct them to place weight on the healing fracture.

The lower limb and knee account for >75% of musculoskeletal injuries in today’s military.

Osteoarthritis is among the leading causes of disability in the United States, costing billions of dollars each year in lost work hours, treatments, and doctor visits, and leaving people sidelined from day-to-day activities. That problem is mirrored and amplified in the military, a unique segment of the population that relies heavily on physical fitness and ability.

AA vs TAA: Update on ankle arthroplasty

End-stage arthritis of the ankle joint affects more than 50,000 people in the US. When conservative treatments do not provide enough relief, surgical options should be considered. Patient selection is key when choosing between ankle arthrodesis (fusion) and total ankle arthroplasty (replacement).

Wearable sensors assess relationship between foot problems and frailty

Assessing how foot problems— namely, pain, neuropathy, and deformity— contribute to frailty syndrome has been a challenge for researchers, as transporting frail elders to lab facilities creates its own set of issues. But a recent study from the University of Arizona used wearable sensors to assess the seniors in their “natural” environment and found significant relationships between the number of foot problems and degree of frailty.

Three-year follow-up: Close contact casting vs surgery

In a pre-specified, 3-year extension of a randomized clinical trial of equivalence, close-contact casting maintained equivalence in function compared to surgery in older adults with unstable ankle fracture. Furthermore, no significant differences were reported in quality of life or pain. The authors concluded that the focus of treatment for these patients should be on obtaining and maintaining reduction until union, using the most conservative means possible.

Lower-extremity amputation feared more than death

Both type 1 and type 2 diabetes are known for their life-threatening complications—in particular, blindness from retinopathy, kidney failure, and peripheral neuropathy. For patients with diabetes and foot pathology, amputation is a significant worry. A recent study in Foot & Ankle Specialist sought to understand just how much this population fears lower-extremity amputation (LEA).

Wasp stings: Some really do hurt more than others, and how to counsel patients

As summer approaches and we become more active outdoors, wasps will become more active, too. Two recent studies highlight the pain and danger of the ubiquitous wasp. The first study, from entomologists at the University of Utah, looked at stinger length compared to reported pain and toxicity.1

Flip flops, bare feet, or sports shoes: Which are best and which are worst?

Many have long suspected the answer, but a new study would appear to resolve the question: Are flip flops really that bad for your feet? According to Chen and colleagues from the Department of Biomedical Engineering at The Hong Kong Polytechnic University, flip flops are most likely no better than barefoot when it comes to lower-limb co-contraction and joint contact force in the ankle.

LER Perspectives


Multidisciplinary views of chronic foot, ankle, and knee-related conditions that curtail activity in otherwise healthy adults

Editor’s note – Welcome to this first installment of a series for the readers of Lower Extremity Review: LER Perspectives. This planned, occasional series is designed to provide multidisciplinary voices to both common and uncommon conditions seen in clinical practice by podiatrists, orthotists and prosthetists, physical therapists, and other clinicians who care for patients with a lower extremity concern.

The goal of the series is to provide a forum for clinicians from an array of specialties to offer perspective on a clinical question or issue.

In this LER Perspective, we asked clinicians in daily practice to identify their most commonly seen foot and ankle and knee conditions that cause previously healthy and active adults to curtail activity. Dr Jay Segel offers the podiatric perspective, Mr Ken Johnson provides the physical therapy perspective, and Dr Kim Ross provides the chiropractic perspective.

Please write to LER with your suggestions for topics that should be covered in a future installment.
