Displaced osteochondral fractures of the body of talus quite often require a malleolar osteotomy to gain access to the fracture fragment during internal fixation. We describe a case report in which access to a displaced osteochondral fracture of the lateral talar dome was achieved using an arthroscopy-assisted fibular tunnel approach. This technique resulted in satisfactory fracture healing and a satisfactory clinical outcome.

Jin Park, Jin Ho Che
Talus fracture of the medial tubercle of the posterior process is rare. This type of fracture can be easily missed, because it is difficult to identify on plain radiographs of the ankle. Oblique radiographs with external rotation, computed tomography, and magnetic resonance imaging (MRI) of the ankle are useful for making an accurate diagnosis. However, even with an early diagnosis, the treatment guidelines for talus fractures of the posterior medial tubercle have not yet been established. The flexor hallucis longus (FHL) tendon, which passes through the groove between the medial and lateral tubercles of the posterior process of the talus, can interpose between the fracture sites and interrupt fracture reduction...

In recent years, regenerative techniques have been increasingly studied and used to treat osteochondral lesions of the talus. In particular, several studies have focused their attention on mesenchymal stem cells derived from adipose tissue. Adipose-derived stem cells (ADSCs) exhibit morphological characteristics and properties similar to other mesenchymal cells, and are able to differentiate into several cellular lines. Moreover, these cells are also widely available in the subcutaneous tissue, representing 10 - 30% of the normal body weight, with a concentration of 5,000 cells per gram of tissue...

INTRODUCTION: Prior to deployment of the Netherlands Army Task Force Urozgan in Afghanistan, the Dutch Military and civilian healthcare systems had limited experience in treating blast injuries and their long-term consequences. This meant that guidelines for treatment and rehabilitation were lacking. The aim of this cohort study was to quantify kinematic and kinetic abnormalities in service members with foot injuries in relation to functional outcome using gait analysis. METHOD: In nine service members with combat-related talus, calcaneus and/or navicular bone (TCN) fractures and nine controls, gait parameters were measured using Gait Real-Time Analysis Interactive Lab system...

Fractures of the talus are challenging to manage, with historically poor outcomes and a high rate of complications. The rare nature of this injury limits the number of studies available to guide treatment. Fortunately, a number of advancements have been made in the last decade. There is increased recognition regarding the importance of anatomic reconstruction of the osseous injury. Advanced imaging is used to assess the subtalar joint, where even slight displacement may predispose to arthritis. Increasing use of dual anteromedial and anterolateral approaches, along with plate fixation, has improved our ability to accurately restore the anatomy of the talus...

BACKGROUND: The anterior drawer test is traditionally used to assess ankle instability, but we believe that there is room for a small but effective improvement by adding digital palpation of the talus. We aimed to determine the accuracy of anterolateral talar palpation (ATP) in the diagnosis of ankle instability by comparing it with the traditional anterior drawer test. METHODS: Fourteen symptomatic and 10 asymptomatic patients were examined for excessive mobility through comparison of both ankles by two blinded orthopedic surgeons, each one using one of the above-mentioned tests...

BACKGROUND: The aim of this study was to assess the inferior talus-superior talus (inf-tal-sup-tal) angle (previously proven reliable in multiplanar-weight bearing imaging (MP-WB)) on both computed tomography (CT) and MP-WB scans. We sought to compare the angle between the two modalities in both AAFD and control groups, as well as to compare the groups to each other. METHODS: Inf-tal-sup-tal angles were compared between a stage II AAFD group (n=38) with routine MP-WB and CT scans and a control group (n=20) with preoperative CT scans for lisfranc injuries and normal hindfoot alignment after healing...

Arthroscopic techniques have recently gained popularity for the treatment of osteochondral defects of the talus. The microfracture procedure is the most commonly applied arthroscopic technique. However, it is not effective for the treatment of larger lesions. Tissue-engineered scaffolds have been used for cartilage regeneration arthroscopically, and promising results have been reported. We treated larger osteochondral lesions of the talus with polyglycolic acid-hyaluronan scaffold biomaterial (Chondrotissue, BioTissue AG, Zurich, Switzerland) in a single-step arthroscopic surgery...

OBJECTIVE To evaluate outcome of limb fracture repair in rabbits. DESIGN Retrospective case series. ANIMALS 139 client-owned rabbits with limb fractures treated between 2007 and 2015. PROCEDURES Medical records were reviewed for information on fracture location, fracture treatment, and time to fracture healing. RESULTS 25 rabbits had fractures involving the distal aspects of the limbs (ie, metacarpal or metatarsal bones, phalanges, and calcaneus or talus). Fractures were treated in 23 of these 25 rabbits (external coaptation, n = 17; external skeletal fixation, 4; and intramedullary pinning, 2) and healed in all 23, with a median healing time of 28 days (range, 20 to 45 days)...

Accessory ossicles of the foot and ankle are normal variants of bone development that usually remain asymptomatic. However, they may be involved in various disorders and become a source of pain such as in fractures, dislocations, degenerative changes, osteonecrosis, osteoarthritis, osteochondral lesions, avascular necrosis, and irritation or impingement of adjacent soft tissues. Hence, during the assessment of the situations above, knowledge about these little-known ossicles could be very important to reach the correct diagnosis...

The midfoot and forefoot are the regions of the foot distal to the talus and calcaneus and are critical to weight bearing and movement. They help support the arch of the foot, provide shock absorption, and convert vertically oriented forces into horizontal forward and propulsive movement. A spectrum of acute, subacute, and chronic conditions in these regions can cause pain and decreased function. A thorough history and physical examination should include foot and leg biomechanics, alignment, and posture in addition to palpation of painful areas...

We have devised a medial peri-articular osteotomy, the distal tibial oblique osteotomy (DTOO), and have used this technique since 1994 for ankle osteoarthritis of advanced and late stages associated with varus inclination. This report describes the surgical technique and its applicability. DTOO can be used for cases of varus ankle osteoarthritis with a range of the ankle joint movement of at least 10° or more. The osteotomy is obliquely directed cut across the distal tibia from proximal-medial to distal lateral and is of an opening-wedge type with the centre of rotation coincident with the centre of the tibiofibular joint...
