Disease relevance of Talus

• Granulomatous infiltration of the talus and abnormal vitamin D and calcium metabolism in a patient with sarcoidosis: successful treatment with hydroxychloroquine [1].
• Coexisting visceral and musculoskeletal anomalies included dextrocardia (3), atrial septal defect (1), congenital vertical talus (2), Sprengel's deformity (1), and multiple unilateral foot anomalies (1) [2].
• Stenosing tenosynovitis of the flexor hallucis longus tendon and posterior impingement upon the os trigonum in ballet dancers [3].
• A rare case of closed complete rupture of the flexor hallucis longus tendon at its groove in the posterior process of the talus is reported in a soccer player who developed pseudarthrosis of the posterolateral tubercle of the talus after a Shepherd's fracture [4].
• The preoperative diagnosis of 16 patients was diabetic neuropathic arthropathy in seven patients, rheumatoid arthritis in three patients, post traumatic arthrosis in three patients, paraplegia with fixed equinovarus of the foot in two patients, and avascular necrosis of the talus in one patient [5].

High impact information on Talus

• A HOX gene mutation in a family with isolated congenital vertical talus and Charcot-Marie-Tooth disease [6].
• HOXD10 M319K mutation in a family with isolated congenital vertical talus [7].
• Isolated foot anomalies, including congenital vertical talus, were shown recently to occur in heterozygous carriers of CDMP-1 (cartilage-derived morphogenetic protein-1) gene mutations [8].
• Four examiners independently examined the coronal images as well as sagittal plane reconstructions for direct (bone-on-bone contact) and indirect (subchondral sclerosis or cysts) evidence of (1) extra-articular contact between the talus and the calcaneus in the sinus tarsi and (2) contact between the calcaneus and the fibula [9].
• The Iowa Pleistocene snail, Discus macclintocki, is an endangered species that survives only in relictual populations on algific (cold-air) talus slopes in northeast Iowa and northwest Illinois in the central region of the USA [10].

Anatomical context of Talus

• A saucer-shaped defect involving the lateral trochlear ridge of the talus and a radiopaque joint fragment were evident on radiographs of the left tarsus in a 6-month-old Rottweiler [11].
• Closed complete rupture of the flexor hallucis longus tendon at the groove of the talus [4].
• Some consultants (different consultants for different fracture regions) did not operate on any complex fracture of the proximal, mid, or distal humerus; proximal, mid, or distal radius or ulna; proximal, mid, or distal femur; proximal, mid, or distal tibia; calcaneum; peri-prosthetic; Lisfranc; or talus fracture during the specific time period [12].
• Radiopaque markers were introduced into the tibia, talus, calcaneus, navicular, medial cuneiform, and first metatarsal bones [13].
• Three cases of complete rupture of the flexor hallucis longus tendon near the metatarsophalangeal joint and three under the sustentaculum tali have been reported, but there have been no reports at the groove of the talus [4].

Associations of Talus with chemical compounds

• Technetium 99 methylene diphosphonate showed intense focal uptake at the posterior talus pointing to the os trigonum as the site of symptoms [14].
• The patient was successfully treated by removing the os trigonum and releasing the flexor hallucis longus tendon [15].
• An unusual case of avascular necrosis of the talus secondary to chronic steroid usage is presented, along with a review of the literature [16].
• PURPOSE: To determine the clinical significance of an increased uptake of 99mTc methylene-diphosphonate (Tc-MDP) in the os trigonum region seen on bone scintigrams of soldiers on active duty [17].
• In 21 feet, a special K-wire was used to derotate the talus in the ankle mortise [18].

Gene context of Talus

• OBJECTIVE: This paper presents four generations of a family with radiographically demonstrated congenital vertical talus (CVT) in whom a HOXD10 gene mutation was identified [19].
• Three reference pins were rigidly mounted in the calcaneus, talus, and shank segments to provide position data in 243 test situations [20].
• Although the number in each group is small, it does not appear that the procedure has merit for the treatment of ankle arthritis from such diverse causes as trauma, rheumatoid arthritis, aseptic necrosis of the talus and talectomy [21].
• Aneurysmal bone cysts localized in the talus are extremely rare [22].
• At the present time, ECD seems to be the most effective treatment strategy for osteochondral defect of the talus [23].

Analytical, diagnostic and therapeutic context of Talus

• Prostaglandin E2 and collagenase release by cultured talus from type II collagen arthritis rats [24].
• Diagnostic imaging of trauma to the ankle and foot. Part III: Fractures and dislocations of the talus [25].
• The most common diagnosis for patients who underwent arthrodesis was post-traumatic arthritis (19 of 21) with 1 patient having a diagnosis of avascular necrosis of the talus and the other patient having rheumatoid arthritis [26].
