Myoepithelioma-like hyalinizing epithelioid tumor of the foot with OGT-FOX03 fusion gene: Imaging findings, surgical implications, and pathological correlates.

Myoepithelioma-like hyalinizing epithelioid tumors are rare neoplasms that share morphological characteristics of myoepitheliomas but lack traditional immunophenotypic findings. Though little is known about these tumors at present, a handful of recent studies have confirmed that they harbor a novel fusion gene known as "OGT-FOXO." Though closely resembling myoeptheliomas, Myoepithelioma-like hyalinizing epithelioid tumors are considered a distinct tumor entity, and few studies have explored their clinical characteristics or their potential for malignancy. Furthermore, literature describing imaging findings of these tumors is virtually non-existent. Understanding the radiological and pathological differences between Myoepithelioma-like hyalinizing epithelioid tumors and myoepitheliomas is helpful in developing a comprehensive differential for soft tissue neoplasms of the foot. We describe a case of MHET of the foot and correlate MRI findings with pathology in addition to describing surgical technique and implications to care.

MR diagnosed chronic exertional compartment syndrome successfully treated by endoscopically-assisted fasciotomy.

Chronic exertional compartment syndrome is a subset of compartment syndrome that most frequently affects the lower extremities, often in athletic persons. It is most often characterized by calf pain shortly after the initiation of exercise and resolution of the pain soon after rest. While the pathophysiology is not completely understood, it is believed that compartment a lack of fascial compliance and increased compartment fluid leads to increased pressure, ultimately leading to a reversible ischemic state. Chronic exertional compartment syndrome was once considered a diagnosis of exclusion; however, needle manometry is an invasive way to measure intracompartmental pressure. Similarly, fasciotomy is the treatment of choice but is not without complications. We describe a case of chronic exertional compartment syndrome diagnosed by two-stage MRI and successfully treated by endoscopically-assisted fasciotomy.

American College of Foot and Ankle Surgeons Clinical Consensus Statement: Appropriate Clinical Management of Adult-Acquired Flatfoot Deformity.

This clinical consensus statement of the American College of Foot and Ankle Surgeons focuses on the highly debated subject of the management of adult flatfoot (AAFD). In developing this statement, the AAFD consensus statement panel attempted to address the most relevant issues facing the foot and ankle surgeon today, using the best evidence-based literature available. The panel created and researched 16 statements and generated opinions on the appropriateness of the statements. The results of the research on this topic and the opinions of the panel are presented here.

Arthroscopic Ankle Arthrodesis: An Update.

Arthroscopic ankle arthrodesis provides an alternative to open techniques. Advancements in arthroscopic techniques and instrumentation have made the procedure easier to perform. Arthroscopic ankle arthrodesis has demonstrated faster rates of union, fewer complications, reduced postoperative pain, and shorter hospital stays. Sound surgical techniques, particularly with regard to joint preparation, are critical for success. Comorbidities such as increased body mass index, history of smoking, malalignment, and posttraumatic arthritis should be considered when contemplating arthroscopic ankle arthrodesis. Although total ankle replacement continues to grow in popularity, arthroscopic ankle arthrodesis remains a viable alternative for management of the end-stage arthritic ankle.

Use of an all-suture anchor for re-creation of the anterior talofibular ligament: a case report.

The lateral ankle ligament complex is typically injured during athletic activity caused by an inversion force on a plantar flexed foot. Numerous open surgical procedures to reconstruct the lateral ankle complex have been described. In contrast, we present a case report in which an all-suture anchor was used arthroscopically to re-create the anterior talofibular ligament in conjunction with ankle arthroscopy. A retrospective analysis of a 55-year-old male with a work-related inversion ankle sprain was performed with 14 months of follow-up. Objective and subjective assessments were obtained using range of motion measures, a strength assessment, and the Foot Function Index. An all-suture anchor was deployed through the anterolateral portal and secured in both the fibula and talus, re-creating the anterior talofibular ligament at its origin and insertion. Active range of motion physical therapy began at 2 weeks postoperatively. The patient started a neuromuscular re-education program at 5 weeks with minimal pain or discomfort. A return to full duty was achieved at 3 months postoperatively. To our knowledge, the use of an all-suture anchor has not been previously reported for lateral ankle complex re-creation. It is hoped that this approach to anterior talofibular ligament repair will decrease the incidence of complications and improve outcomes.
