A Unique Dressing
A new dressing attacks wounds from more than one angle.
Biostep™ Ag Collagen Matrix Dressings use a unique dual-action approach to target and deactivate excess matrix metalloproteinases (MMPs), according to the manufacturer Smith and Nephew Wound Management.
The company says the dressings also use the antimicrobial effects of silver to minimize the chance of infection.
Smith and Nephew says Biostep has a six-day wear time and is more absorbent than other dressings.

Two abstracts, which will be presented at the upcoming Symposium on Advanced Wound Care (SAWC), seek to address the impact of dialysis upon diabetic wound healing and the long-term mortality rates of those who undergo non-traumatic amputation.
For the one abstract’s retrospective review, researchers evaluated 150 patients with diabetes on hemodialysis. These patients had 30 months of follow-up for foot ulcers, infections, amputations and death. The abstract authors sought to determine if the patients received “standard preventative care” consistent with patien

Tarsal tunnel syndrome is an entrapment of the posterior tibial nerve or its branches within the tarsal tunnel.1 This syndrome is most frequently unilateral as opposed to carpal tunnel syndrome in the upper extremity, which is typically bilateral.2 Keck and Lam first described the term “tarsal tunnel syndrome” in 1962.3,4
Malaisé first described the clinical signs and symptoms of tarsal tunnel syndrome in 1918. Some of the symptoms include numbness or tingling in the soles of the feet and toes or a burning pain in the ankles.
Technology In Practice »
For podiatric surgeons who are looking for new additions to their internal fixation armamentarium, the NexFix RFS (Resorbable Fixation System) Pin may be a viable option.
The NexFix RFS Fin offers a combination of self-locking technology and a patented grooved surface design. Tornier, the manufacturer of the product, says the RFS Pin provides enhanced rotational stability, improved flexibility to accommodate different drill hole sizes and channels for potential vascularization.
Charles Zelen, DPM, notes he has had success using the NexFix RFS Pin for various osteotomies.
Treatment Dilemmas »
Ankle arthritis has been the subject of much research and researchers have made a great deal of progress in this area in the past 50 years. In the past, physicians primarily treated post-traumatic arthritis, which accounts for much of the cause of ankle arthritis, with casting. This often caused malalignment and poor articular position, resulting in rapid arthritis of the hindfoot and ankle.
With the advent of internal fixation and external fixation advances, proper anatomic alignment of the hindfoot and ankle has resulted in a dramatic decrease in the rate of post-traumatic ar
Wound Care Q&A »
When it comes to patients with diabetes and lower extremity ulcers and complications, what does the evidence-based medicine say about high-risk patients and proactive prevention? These panelists examine risk factors for ulcerations, appropriate screening and offer their thoughts on what works and what does not work in terms of prevention.
Q: What does evidence-based medicine show in regard to who is at risk for limb loss and foot ulcerations?
A: Thomas Zgonis, DPM, says approximately 15 percent of patients with diabetes will experience a
