Posterior Ankle Impingement.

This article is devoted to managing posterior ankle impingement syndrome and its management using endoscopic to arthroscopic surgical instrumentation. The authors explore the critical anatomy, pathogenesis, and clinical examination. Operative techniques, including the approach, and instrumentation used, are outlined. The postoperative protocol is discussed. Finally, a literature review is provided, which also defines known complications.

Anatomic and Biomechanical Considerations of Flatfoot Deformity.

In this article, the authors present essential anatomy in the presence of the postural flat foot. There is a recognition of static versus dynamic stabilizers of the foot. In the continuum of the collapsed foot, there is an exploration of anatomic and pathologic changes. Providing this fundamental knowledge will allow the reader to appreciate the disease process to establish a prognosis and consider treatment alternatives.

Outcomes of Partial Calcanectomy in an Academic Limb Salvage Center: A Multicenter Review.

Chronic nonhealing heel ulcerations have been established as an independent risk factor for major amputation, with poor rates of limb salvage success. Partial calcanectomy is a controversial limb salvage procedure reserved for patients with these heel ulcerations. We conducted a retrospective cohort study reviewing 39 limbs that underwent a partial calcanectomy from 2012 to 2018 to evaluate the proportion of patients healed, time to healing, ulcer recurrence, and postoperative functional level compared to the preoperative state. In addition, age, gender, body mass index, smoking status, coronary artery disease, diabetes mellitus, renal insufficiency, dialysis, peripheral arterial disease, method of closure, and percent of calcaneus resected were evaluated. Mean follow-up for our cohort was 2.3 years. We had a 1 year mortality rate of 11%, and a major amputation rate of 18%. Our results demonstrated a 77% healing rate with a median time to healing of 162 days. We found that patients who were closed primarily had a faster time to healing compared to patients who underwent closure by secondary intention. Our data showed that ulcer recurrence developed in 57% of healed limbs. We found that 76% of our patients were ambulatory postoperatively. These results suggest that partial calcanectomy is a viable limb salvage procedure with a predictable level of ambulation and function in a high-risk patient population.

Nonoperative Treatment of Plantar Plate Tears.

The plantar plate is a critical structure involved in stabilizing the metatarsophalangeal joint. Its disruption can not only be painful for the patient but also may lead to subsequent structural deformities. There are several conservative treatment modalities available to help mitigate symptoms including splinting, offloading, and intraarticular injections. That being said, once the pathology progresses to advanced stages, these treatments are not efficacious. Reported success with conservative treatment modalities is limited to case studies and series with a low level of clinical evidence. As such, this represents an area where further investigation is needed to evaluate the true efficacy of conservative treatment and to allow for development of a more standardized approach.
