Isidro Jimenez, Juan Pedro Rodriguez-Alvarez, Ricardo Navarro-Navarro
Fracture-dislocations of the tarsal navicular are rare and highly complex injuries to the midfoot. The only published data on this type of fracture are clinical case reports. These injuries are normally caused by high-energy trauma, and their pathophysiology and most appropriate treatment remain unclear. We report a clinical case of a dorsal fracture-dislocation of the tarsal navicular bone associated with a medial swivel dislocation of the Chopart joint caused by a bicycle fall in a 20-year-old healthy man...

Glomus tumors are painful benign neoplasms. They commonly present in the hand and are mostly solitary lesions. We report a rare case of multiple glomus tumors in the lower leg. Moreover, 1 of the tumors was in the tarsal tunnel. Resection of the tumors resulted in the early diagnosis of glomus tumors and complete symptom relief. Because of its rarity, diagnosing an extradigital glomus tumor is difficult. Recognition of glomus tumors allows for an early diagnosis and resection, and preoperative magnetic resonance imaging helps in the detection of multiple lesions...

Posteromedial subtalar (PMST) coalitions are a recently described anatomic subtype of tarsal coalitions. We compared with clinical patient-based outcomes of patients with PMST and standard middle facet (MF) coalitions who had undergone surgical excision of their coalition. The included patients had undergone surgical excision of a subtalar tarsal coalition, preoperative computed tomography (CT), and patient-based outcomes measures after surgery (including the American Orthopaedic Foot and Ankle Society [AOFAS] scale and University of California, Los Angeles [UCLA], activity score)...

Anurans have three primary types of locomotion: walking, jumping, and swimming. Additionally, they may dig, climb, grasp, etc. All adult anurans have four limbs, with four fingers on the hands and five toes on the feet. We summarized and updated knowledge on the interspecific variation within anuran limbs, then discuss how developmental constraints (e.g., in size) and novelties may have influenced anuran diversification through the locomotion. We analyze morphological variation from limb bud stages up to the final limb form resulting from certain skeletal organization and growth...

A new species of the genus Amolops Cope, 1865 is described from Xinduqiao, Kangding, Sichuan. It was previously identified as Amolops kangtingensis, which is synonymized to Amolops mantzorum in this study. The new species, Amolops xinduqiao sp. nov., is distinguished from all other congeners by the following combination of characters: (1) medium body size, adult males SVL 41.2-47.5 mm ( n=15, average 43.9 mm), adult females SVL 48.5-56.6 mm ( n=15, average 52.5 mm); (2) head length equal to width or slightly wider than long; (3) tympanum small, but distinct; (4) vomerine teeth in two tiny rows, separated by a space about one vomerine teeth row; (5) bony projections on lower jaw absent; (6) dorsolateral folds usually absent; (7) tarsal folds or glands on tarsus absent; (8) circummarginal groove on disc of finger I absent; (9) tibiotarsal articulation reaching nostril or beyond; (10) webs of toe IV reaching to distal articulation, other toes fully webbed to disc; and (11) vocal sac absent in males...

A 74-year-old man was examined for a mass in the left upper eyelid. It was inconspicuous in inspection. There was no visual restriction, however a feeling of friction on the superior orbit during lid movement. Through eyelid crease lid incision, a solitary lesion appeared in the preaponeurotic space that orginated from the upper tarsal plate. Excisional biopsy revealed adipose proliferation with patch form vessels. This case represents the second reported angiolipoma of the eyelid in English literature.

REVIEW
Lawrence A DiDomenico, Danielle N Butto
Subtalar joint arthrodesis is a procedure used in posttraumatic arthritis, osteoarthritis, tarsal coalition management, posterior tibial tendon dysfunction, and inflammatory arthropathies, and can be used in deformity correction. The goals of the procedure are to eliminate pain, improve function, restore stability, and realign the hind foot. The procedure has high patient satisfaction with low complications while preserving motion in adjacent tarsal joints. Joint preparation is important and time should be spent preparing the joint for successful arthrodesis and the fixation construct needs to be done well and effectively to provide a solid Arbeitsgemeinschaft für Osteosynthesefragen (AO) construct for good results...

The presence of well-developed, elastic claws on ticks and widely pilose hosts led us to hypothesise that ticks are mostly adapted to attachment and locomotion on rough, strongly corrugated and hairy, felt-like substrates. However, by using a combination of morphological and experimental approaches, we visualised the ultrastructure of attachment devices of Ixodes ricinus and showed that this species adheres more strongly to smooth surfaces than to rough ones. Between paired, elongated, curved, elastic claws, I...

Rarely, osteochondral lesions of the talus occur without a history of trauma. Accurate interpretation of the mechanical load distributions onto the ankle leading to potential atraumatic cartilage damage must always be studied. The published data on the optimal treatment of talar osteochondral lesions in skeletally immature patients are scarce, especially when the lesions are associated with hindfoot malalignment. We describe the case of a pediatric female with an atraumatic osteochondral lesion of the talus associated with a talocalcaneal coalition and a valgus hindfoot, which we consider the first case to be reported...

Tetsuya Kojima
Insects show a tremendous morphological variety and have been a subject of studying morphological evolution. In legs, the tarsus is especially variable in the number of subsegments (tarsal segments) and their proportion unlike other leg segments. Recent studies in Drosophila melanogaster have revealed details of the tarsal development: regionalization of the tarsal region through integration of regulatory network and its growth, determination of the joint-forming region in each segment through strict regulation of Notch activity, changes in tissue morphology through regulation of RhoGTPases regulators and localized cell death, and finally, the morphogenetic mechanism of the ball-and-socket joint between tarsal segments...

Chameleon species have recently been adopted as models for evo-devo and macroevolutionary processes. However, most anatomical and developmental studies of chameleons focus on the skeleton, and information about their soft tissues is scarce. Here, we provide a detailed morphological description based on contrast enhanced micro-CT scans and dissections of the adult phenotype of all the forelimb and hindlimb muscles of the Veiled Chameleon (Chamaeleo calyptratus) and compare these muscles with those of other chameleons and lizards...
