Out on a limb: Beyond offloading

Lower extremity practitioners are constantly being reminded that what they think they know about injury prevention is only part of a bigger picture. This time it’s the diabetic foot care community’s turn to wonder just how much they have yet to learn about the mechanisms underlying ulceration.

Debating the complexities of partial foot amputation

Partial foot amputations may not offer a biomechanical advantage over transtibial amputations if the metatarsal heads cannot be retained, and some experts suggest amputation level should be selected based on probability of wound healing instead. But others disagree.

Ankle arthroplasty makes strides, but issues remain

Study findings and anecdotal reports suggest that newer-generation total ankle replacement can match or exceed ankle arthrodesis when it comes to gait and range of motion, but neither procedure returns gait to normal. Implant survival has also improved, but continues to be a challenge.

Total hip arthroplasty: Obesity and outcomes

Total hip arthroplasty can significantly improve quality of life in obese patients, but high body mass index is also associated with higher rates of complications and re­admissions than in normal-weight patients. The emerging subgroup of super-obese patients poses additional challenges.

Biofilms: Diabetic foot ulcer care gets personal

Opportunistic microorganisms called bio­films constitute an age-old diabetic wound care problem that defies traditional anti­microbial therapies. Experts believe interventions customized to individual patients based on molecular diagnostics may be the best line of defense.

Platelet-rich plasma: An option for tendinopathy

Patients with chronic refractory lower extremity tendinopathies often continue to have symptoms after exhausting most of their therapeutic options. Preliminary evidence supports the use of platelet-rich plasma in these patients, though higher-level research is needed.

In the Moment: Diabetes

Location, location: High pressures don’t predict all ulcers

Practitioners often deem all areas of elevated peak plantar pressure in patients with diabetes at some risk for ulceration. A study published in September, how­ever, suggests this risk varies with the specific location of pressure, and investigators say findings highlight the importance of monitoring plantar pressure as part of preventive care.

Neuropathy results in less sensory loss at fifth metatarsal than hallux

Clinicians should carry out quantitative vibration testing for sensory loss in patients at risk for diabetic neuropathy at the hallux, according to research that confirms the hallux undergoes greater sensory loss than the fifth metatarsal, an alternate location for vibration testing.

Imaging reveals intrinsic muscle deterioration in neuropathic feet

Diabetic neuropathy is associated with increased levels of intrinsic foot muscle deterioration, which may contribute to foot deformity and ulceration, according to research presented in September at the annual meeting of the American Society of Biomechanics in Omaha, NE.

Investigating OA: Studies revisit underlying variables

Knee osteoarthritis researchers are taking a closer look at the factors that influence knee adduction moment (KAM) and also considering the contributions of sagittal plane variables, as illustrated by studies presented in September at the American Society of Biomechanics (ASB) annual meeting in Omaha, NE.

Altered landings suggest link between neurocognitive scores, ACL injury risk

Female athletes with low neurocognitive scores are more likely than those with higher scores to demonstrate altered landing mechanics consistent with elevated anterior cruciate ligament (ACL) injury risk, according to findings that could have implications for concussion management.

Limited arch excursion characterizes individuals with patellofemoral pain

Patients with patellofemoral pain (PFP) have less medial longitudinal arch excursion during stair descent than healthy individuals, according to a Brazilian study that may help explain the effects of foot orthoses in patients with PFP.
