Three-dimensional kinematics at the ankle joint complex in rheumatoid arthritis patients with painful valgus deformity of the rearfoot

A recent paper from Denmark1 reports that radiologically visible calcification of tibial arteries in the ankle-joint region was three times as frequent in a group of patients with rheumatoid arthritis who had received corticosteroids for more than six months as in a control group of patients. The author claims that this increased incidence was due to the corticosteroids.

Minimal Brain Dysfunction

The most common feet pathologies of children are valgus and valgus planus deformities, which are congenital or connected with neurological dysfunctions (Minimal Brain Dysfunction). In adults, and mostly in women, we observe: 1. Köhler’s disease among girls wearing improper shoes. 2. Insufficiency and pain of the front part of feet connected with limited toes flexion, 3. Valgus deformity of the big toes (hallux valgus), 4. “Ankle Joint Pain Syndrome” (AJPS)-sometimes also “Knee Joint Pain Syndrome” (KJPS)-described by us only in USA, India and Czech Republic. In presented article, we describe this special type of foot insufficiency- “instability of ankle or knee, or both joints”-on left leg in drivers and right leg in passengers in countries with right-hand traffic. More frequent it concerns the foot and article focus on this problem.

Mortise View

Background: Syndesmosis is an important soft tissue component supporting the ankle stability and commonly injured accompanying with ankle fractures. The accurate reduction and fixation of syndesmosis is essential to obtain better functional results. Therefore, we aimed to find a practical method using the mortise view of ankle to determine the optimal syndesmosis fixation angle intraoperatively. Methods: We randomly selected 200 adults (100 women and 100 men) between 18 - 60 years of age. Three-dimensional anatomical models of tibia and fibula were created using Materialise MIMICS 21. We created a best fit plane on articular surface of medial malleolus and a ninety degrees vertical plane to medial malleolus plane. We determined two splines on cortical borders of tibia and fibula distant from the most superior point of ankle joint in horizontal view. We created two spheres that fit to the predefined splines. The optimal syndesmosis fixation angle was determined measuring the angle between the line connecting the center points of spheres, and the ninety degrees vertical plane to medial malleolus plane. Results: We observed no statistically significant difference between gender groups in terms of optimal syndesmosis fixation angles. The mean age of our study population was 47.1 {plus minus} 10.5. The optimal syndesmosis fixation angle according to mortise view was found as 21 {plus minus} 4.3 degrees. Conclusions: We determined the optimal syndesmosis fixation angle as 21 {plus minus} 4.3 degrees in accordance with the mortise view of ankle. The surgeon could evaluate the whole articular surface of ankle joint with the medial and lateral syndesmotic space in mortise view accurately and at the same position syndesmosis fixation could be performed at 21 {plus minus} 4.3 degrees.
