The Yakumo Wind-hole in southwest Japan formed by landslip, and it is known as a cold air blowhole. This wind-hole consists of two parts, which have complementary relationships in regard to the flow of air, namely, topographically upper and lower holes that can be characterized as a warm wind-hole (WWH) and cold wind-hole (CWH), respectively. We carried out a preliminary investigation of radon behavior in the Yakumo Wind-hole. Read More

Introduction: Recent studies suggest that hindfoot deformity should be considered in the surgical treatment of tarsal coalitions. Many authors have used the angle between the talus and the calcaneus (TCA) for decision-making. However, its reliability has not been demonstrated and the measurement technique has not been standardized. Read More

Deltoid ligament reconstruction following type B ankle fractures continues to generate a vivid discussion amongst trauma surgeons. There is a difference of opinion as to whether operative or non operative treatment should prevail. We therefore conducted a prospective comparative cohort study to determine whether it is necessary to routinely repair the injured deltoid ligaments. Read More

Contact pressures in the articular cartilage during gait affect injuries and the degenerative arthritis of knee and ankle joints. However, only contact forces at the knee and ankle joints during gait can be estimated by using a rigid body dynamic model. The contact pressure distribution can be obtained quantitatively for a static posture by using finite element (FE) analysis in most cases. Read More

The last stage of a supination-external rotation ankle fracture involves either transverse fracture of the medial malleolus or rupture of the deltoid ligament. When the deltoid ligament ruptures, a "bimalleolar equivalent" ankle fracture occurs, and the surgeon is presented with several diagnostic and therapeutic challenges. In the native ankle, the deltoid ligament provides restraint to eversion and external rotation of the talus on the tibia. Read More

Backgroud: To evaluate reliability of Bohler angle in doing operative reduction of fractured calcaneus, and compare its value over other image lines of hindfoot when surgeons determine whether the injured calcaneus is reduced close to pre-injured state.

Methods: Eighteen of postoperative lateral radiographs were obtained and edited with two versions; one of which anterior of calcaneus erased not to check Bohler angle, the other of which peri-calcaneus structure such as talus erased only to check Bohler angle. Four orthopaedic surgeons were asked to determine the two sets of images whether the injured calcaneus is reduced close to pre-injured state in independent two sessions. Read More

In High Arctic tundra ecosystems, seabird colonies create nitrogen cycling hotspots because of bird-derived labile organic matter. However, knowledge about the nitrogen cycle in such ornithocoprophilous tundra is limited. Here, we determined denitrification potentials and in-situ nitrous oxide (NO) emissions of surface soils on plant-covered taluses under piscivorous seabird cliffs at two sites (BL and ST) near Ny-Ålesund, Svalbard, in the European High Arctic.

Salter-Harris type I fractures of the distal tibia are commonly seen in paediatrics and management of such fractures follows an algorithm established in the literature. Despite this, osteonecrosis of the distal tibia can subsequently develop. Osteonecrosis or avascular necrosis is cell death that occurs secondary to trauma, metabolic disturbances, sickle cell disease, or medication side effect. Read More

In unstable ankle fractures, the importance of reducing the lateral malleolus first to obtain an anatomic reduction of the talus is well established. Although this is a time-tested and common surgical approach, current surgical practice does not always follow the established dogma. Medial-first fixation may be a worthwhile alternative to lateral-first fixation in select instances. Read More

Lateral inverted osteochondral fracture of the talus (LIFT) is a rare variant of stage IV osteochondral lesion of the talus (OLT), where the fragment is inverted in situ by 180°. The management of LIFT lesion is very challenging and early recognition crucial, given that treatment options depend on the articular cartilage condition and sufficiency of the adjacent bone of the displaced fragment. We describe two LIFT cases referred from other institutions after unsuccessful conservative treatment of OLT. Read More

Surgical techniques for the management of recalcitrant osteochondral lesions of the talus have improved; however, the poor healing potential of cartilage may impede long-term outcomes. Repair (microfracture) or replacement (osteochondral transplants) is the standard of care. Reparative strategies lead to production of fibrocartilage, which, compared with the native type II articular cartilage, has decreased mechanical and wear properties. Read More

Purpose: To clarify if the use of concentrated bone marrow aspirate (CBMA) would affect both postoperative functional outcomes and magnetic resonance imaging (MRI) outcomes compared with those of autologous osteochondral transplantation (AOT) alone; in addition, to assess the efficacy of CBMA reducing the presence of postoperative cyst formation following AOT in the treatment of osteochondral lesions of the talus.

Methods: Fifty-four (92%) of 59 eligible patients who underwent AOT between 2004 and 2008 were retrospectively assessed at a minimum of 5-year follow-up. Twenty-eight patients were treated with AOT and CBMA (AOT/CBMA group) and 26 patients were treated with AOT alone (AOT-alone group). Read More

Background: Restoration of anatomical relationship between talus and tibia is crucial for longevity of total ankle replacement (TAR). Weight-bearing (WB) radiographs are the standard for evaluating the sagittal balance alignment, but are prone to rotational misalignment and altered measurements.
