To examine a common plantar tendinous plate for long flexors of the toe and fingers in human embryos, we observed sections of 10 embryos at 5-6 weeks (crown-rump length or CRL 15-21 mm). The heel or tuber of the calcaneus was underdeveloped in 3 embryos with CRL 15 mm and the talus appeared not to be piled up on the calcaneus but these two bones were arranged along the lateromedial axis. As reported in the hand, we demonstrated, in the deep side of tarsal bones, a common tendinous plate formed by a joining of the flexor halluces longus and flexor digitorum longus tendons...

Although, trauma, foot deformity (pesplanovalgus), systemic diseases such as diabetes mellitus and lupus, drugs (steroids, antineoplastic) and excessive alcohol consumption have all been accused in the etiology of avascular necrosis of the tarsal bones, spontaneous avascular necrosis of the navicular bone, especially in adults, is a rare entity. In this article, we report a 50-year-old female patient with bilateral, spontaneous avascular necrosis of the navicular bone and related severe talonavicular arthrosis...

PURPOSE: Grading of disease activity in patients with atopic keratoconjunctivitis (AKC) is limited by intra- and inter-observer variability. The aim of this study was to identify angiographic parameters to help evaluate inflammation and disease activity. METHODS: In 12 patients (4 with active, 2 with inactive AKC, and 6 controls), disease activity were assessed using a validated biomicroscopic grading scale. Imaging of upper tarsal conjunctiva was undertaken using color photography, fluorescein (FA) and indocyanine green angiography (ICGA)...

REVIEW
Julia Crim
Abnormalities of the medial ligaments and posterior tibial tendon can occur because of acute injury or chronic instability or malalignment. Medial ankle injuries may occur because of pronation or supination-external rotation injuries. Deltoid ligament injuries have a significant impact on lateral ankle instability but can be overlooked in patients with lateral ligament injuries. Posterior tibial tendon dysfunction is usually associated with spring ligament or flexor retinaculum injury. Tarsal tunnel syndrome, accessory flexor muscles, and subtalar coalition should be considered as well as ligament and tendon tears in differential diagnosis of chronic medial ankle pain...

REVIEW
Yvonne Cheung
Accessory muscles around the ankle are commonly encountered as incidental findings on cross-sectional imaging. Mostly asymptomatic, accessory muscles sometimes mimic mass lesions. They have been implicated as the cause of tarsal tunnel syndrome, impingement of surrounding structures, and chronic pain. Distinguishing these muscles can be challenging, because some travel along a similar path. This article describes these accessory muscles in detail, including their relationships to the aponeurosis of the lower leg...

: Common surgical treatment of first tarsal-metatarsal arthritis is by first metatarsocuneiform joint arthrodesis. While crossed-screw and locking plate fixation are the most widely used methods, a novel construct was designed to alleviate soft tissue irritation while still providing stable fixation. Using anatomic first metatarsal and medial cuneiform composites, we compared 3 arthrodesis implants (crossed-screw, dorsal locking plate, and IO Fix) under 2 cyclic bending loading scenarios (cantilever and 4-point bending)...

Tendon rupture in dogs is generally the result of a direct trauma. This report described the use of adjacent muscle autogenic fascial graft for reconstruction of distal rupture of long digital extensor tendon in a dog. A two-year-old male mix breed dog, was presented with a non-weight bearing lameness of the right hind limb and a deep rupture of lateral side of right tarsus. History taking revealed that this rupture appeared without any apparent cause, when walking around the farm, three days before. Radiography was done and no fracture was observed...

PURPOSE: To report the long-term stability of tarsal margin rotation and posterior lamellar superadvancement (TMR PLS) for the repair of upper eyelid cicatricial entropion. METHODS: A retrospective chart review was performed from January 2000 through December 2014 to identify all patients who had TMR PLS at the authors' institution. Charts were reviewed for demographic information, recurrence of entropion or trichiasis, and surgical complications. Failure was defined as return of entropion...

Injuries of the plantar soft tissues of the tarsus and proximal metatarsus can be a source of lameness in horses, however published information is lacking on high field MRI characteristics of these tissues. Objectives of the current anatomic study were to (1) describe high-field MRI features of the plantar tarsal and proximal metatarsal soft tissues; and (2) compare MRI findings with gross and histological appearances of selected structures for a sample of cadaver limbs from non-lame horses. Single hindlimbs for 42 horses, and right and left hindlimbs for eight horses were scanned using high-field MRI...

Posterior ankle pain is a cause of chronic pain and disability, afflicting a wide range of individuals. While proper identification of the cause is essential for timely and adequate treatment, identifying the cause and excluding mimickers is often challenging for the physician due to the complex nature of the joint. In addition, pathology that can cause posterior ankle pain may occur on their own or in co-existence. Clinical conditions that can present as posterior ankle pain include: posterior ankle impingement, Achilles tendon pathology, medial flexor tendon pathology, peroneal pathology, retrocalcaneal bursitis, posterior subtalar tarsal coalition, sinus tarsi, and tarsal tunnel syndrome...

Many insects possess adhesive foot pads, which enable them to scale smooth vertical surfaces. The function of these organs may be highly affected by environmental conditions. Ladybird beetles (Coccinellidae) possess dense tarsal soles of tenent setae, supplemented with an adhesive fluid. We studied the attachment ability of the seven-spotted ladybird beetle (Coccinella septempunctata) at different humidities by horizontal traction experiments. We found that both low (15%) and high (99%) relative humidities lead to a decrease of attachment ability...

Chorthippus vagans is a common species of Gomphocerinae (Orthoptera) on the Iberian Peninsula. It is endangered in Central Europe where information about its ecological requirements is available; however, aspects of its biology are almost unknown in Mediterranean ecosystems, where it is widespread and common. The focus of this study was to determine how C. vagans adjusts its biology to environmental features of this ecosystem and to interpret how it may be affected by the ecological changes related to the re-vegetation programme linked to the construction of the Breña dam (SW Spain)...

PURPOSE: Our purpose was to assess our outcomes in involutional lower eyelid ectropion and entropion surgery after horizontal eyelid tightening by a modified tarsal strip technique. METHODS: A prospective study of 88 eyelids with ectropion and 96 with entropion was performed. Patients were randomly distributed into two groups: the control group included 90 eyelids (46 entropion and 44 ectropion) and the other group of 94 eyelids (50 entropion and 44 ectropion). The control group was treated with a conventional tarsal strip, whereas the second group underwent the same surgery except for a modified suture placement of the tarsal strip different in patients with ectropion and entropion...

: This case presentation describes a 47-year-old woman who developed complex regional pain syndrome type II with severe neuropathic pain following iatrogenic transection of the tibial nerve at the ankle. The pain and disability progressively worsened over time, markedly impaired ambulation, and were not relieved despite various analgesic treatments. After injection of botulinum toxin (abobotulinumtoxinA, BoNT-A) in the leg muscles the tendons of which pass through the tarsal tunnel (together with the tibial nerve), her pain decreased and her walking capacity improved...

Pachydermoperiostosis is a rare genetic disease that causes major bone and skin changes. Severe ptosis is a prominent finding in this peculiar condition. We report here 2 patients with typical features of pachydermoperiostosis. Their tarsal plates were enlarged and infiltrated by sebaceous gland tissue. One patient also displayed diffuse intratarsal lacrimal gland hyperplasia. As far as we know, this is the first report of ectopic lacrimal tissue in pachydermoperiostosis. Tarsal and skin morphologic changes should be addressed during ptosis correction in these patients...

A 14-year-old boy reported with congenital deformity of the left lower limb, with gross shortening, hip and knee flexion deformities, ankle with equinus deformity, and polydactyly of the left foot. Radiologic examination showed proximal femoral focal deficiency, double fibula, and duplication of the tarsal bones, and a diagnosis of 'proximal femoral focal deficiency associated with fibular duplication and diplopodia with complete agenesis of tibia' was made. Such association of deformities is very rare and poses difficulties in rehabilitation of the case...
