Plantar Vein Thrombosis in a Patient with COVID-19: Case Report.

Plantar thrombophlebitis is a rare abnormality with few cases reported in the literature. Coexistence with severe acute respiratory syndrome coronavirus 2 infection increases its relevance. The disease is generally classified as idiopathic, and it is suggested that it is attributed to conditions that lead to hypercoagulability.

ARTHROSCOPIC FOOT AND ANKLE SURGERY: BRAZILIAN SURGEON PROFILE.

Objective: To study the profile of the practice of arthroscopy among ankle and foot surgeons in Brazil and its evolution in recent years.

Methods: Observational, cross-sectional study, using a survey sent to all members of the (ABTPé) in 2017 and 2019.

Results: In total, 75 surgeons participated in 2017 and 82 in 2019 and most had over 10 years of experience.

Reliability of Two Smartphone Applications for Radiographic Measurements of Hallux Valgus Angles.

The objective of the present study was to assess the reliability of 2 smartphone applications compared with the traditional goniometer technique for measurement of radiographic angles in hallux valgus and the time required for analysis with the different methods. The radiographs of 31 patients (52 feet) with a diagnosis of hallux valgus were analyzed. Four observers, 2 with >10 years' experience in foot and ankle surgery and 2 in-training surgeons, measured the hallux valgus angle and intermetatarsal angle using a manual goniometer technique and 2 smartphone applications (Hallux Angles and iPinPoint).

Endoscopic treatment of the posterior ankle impingement syndrome on amateur and professional athletes.

Purpose: To determine whether professional and amateur athletes showed differences in ankle function when treated with endoscopic technique for posterior ankle impingement syndrome, to verify the impact of the presence of associated lesions in clinical evolution and to assess time to return to sport (we hypothesize that time will be the only difference between groups).

Methods: Thirty-two athletes with a diagnosis of posterior impingement syndrome underwent surgery endoscopically. The American Orthopaedics Foot and Ankle Society (AOFAS) scale was used to compare functional results between amateur (15) and professional athletes (17).

Peroneal tenodesis with the use of tendoscopy: surgical technique and report of 1 case.

Peroneus brevis tendon injury is the most common lesion of the peroneal tendons. The initial treatment is conservative, and surgical treatment is indicated if conservative treatment fails. It is often necessary to open the entire upper and lower retinaculum to obtain adequate visualization of the structures.
