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...

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...

Rodent models are used for a variety of orthopedic research applications; however, anatomy references include mostly artistic representations. Advanced imaging techniques, including micro-computed tomography (microCT), can provide more accurate representations of subtle anatomical characteristics. A recent microCT atlas of laboratory mouse (Mus musculus) anatomy depicts the central and tarsal bone III (T3) as a single bone, differing from previous references. Fusion of tarsal bones is generally characterized as pathological secondary to mutations associated with growth factors, and normal variation has not been documented in the mouse tarsus...

OBJECTIVES: The objective of the current study was to examine trends in ankle/foot (A/F) injuries during the period 2001-2014, in order to determine whether the incidence of these injuries has changed and whether a previously identified difference in risk by gender still existed. In addition, other driver and crash-related risk factors were examined separately for men and women. METHODS: Passenger vehicle drivers aged 16+ were identified from NASS-CDS; weighted data were analyzed for model years 2001-2014...

Juvenile bovine patients who present with clinical signs of lameness are commonly evaluated using radiographic techniques both within a hospital setting and in a farm environment. The radiographic development of the juvenile bovine skeleton is currently poorly documented. In this study, the limbs of four heifer calves were sequentially radiographed to assess development of the juvenile bovine appendicular skeleton in the first 12 months of life. Images were acquired at three weeks, three months, six months, nine months and one year of age...

Osteochondroma or exostosis is the most common benign bone tumor, and occurring frequently in the proximal humerus, tibia, and distal femur. It rarely affects talus. Osteochondroma of talus is a very rare etiology of tarsal tunnel syndrome (TTS). We report a rare case of extensive osteochondroma of the talus in a 60 year old female presenting with multiple swellings around the ankle and symptoms suggestive of tarsal tunnel syndrome. En-block excision of the multiple masses was done. Histopathological examination confirmed the diagnosis of osteochondroma...

A technique for using free autogenous omental grafting with arthrodesis in dogs is described and radiographic osseous union and complications after surgery are evaluated. This retrospective study matched body weight and procedure type for 8 cases of pancarpal arthrodesis, 4 cases of pantarsal arthrodesis, and 2 cases of partial tarsal arthrodesis in dogs with omental and cancellous bone autograft (OBG group) and with cancellous bone autograft alone (BG group). Radiographs were reviewed 9 to 12 weeks after surgery to compare scores of radiographic osseous union and it was found that the OBG group had higher scores than the BG group...

Australopithecus africanus has been interpreted as having a rigid lateral foot. One mechanism contributing to a rigid foot during push-off in humans is a calcaneocuboid joint (CCJ) with limited dorsiflexion and a "close-packed" talocalcaneal joint (TCJ). In contrast, apes likely have a greater CCJ range of motion and lack a close-packed TCJ. Differences in tarsal arthrokinematics may result in different joint loading environments. In Homo sapiens, we tested the hypothesis that dorsal and plantar CCJ and the TCJ show evidence of predictable habitual loading...

Cardiospondylocarpofacial (CSCF) syndrome is characterized by growth retardation, dysmorphic facial features, brachydactyly with carpal-tarsal fusion and extensive posterior cervical vertebral synostosis, cardiac septal defects with valve dysplasia, and deafness with inner ear malformations. Whole-exome sequencing identified heterozygous MAP3K7 mutations in six distinct CSCF-affected individuals from four families and ranging in age from 5 to 37 years. MAP3K7 encodes transforming growth factor β (TGF-β)-activated kinase 1 (TAK1), which is involved in the mitogen-activated protein kinase (MAPK)-p38 signaling pathway...

The tarsal bones articulate with each other and demonstrate complicated kinematic characteristics. The in vivo motions of these tarsal joints during normal gait are still unclear. Seven healthy subjects were recruited and fourteen feet in total were tested in the current study. Three dimensional models of the tarsal bones were first created using CT scanning. Corresponding local 3D coordinate systems of each tarsal bone was subsequently established for 6DOF motion decompositions. The fluoroscopy system captured the lateral fluoroscopic images of the targeted tarsal region whilst the subject was walking...

AIMS: Although infrequent, a fracture of the cuboid can lead to significant disruption of the integrity of the midfoot and its function. The purpose of this study was to classify the pattern of fractures of the cuboid, relate them to the mechanism of injury and suggest methods of managing them. PATIENTS AND METHODS: We performed a retrospective review of patients with radiologically reported cuboid fractures. Fractures were grouped according to commonly occurring patterns of injury...

A 3-year-old Labrador Retriever originating from Spain was presented with a left-sided hind limb lameness for several months. The orthopedic examination revealed a pain response when palpating the left tarsal joint. Radiographic and computed tomographic studies showed polyostotic, aggressive osteolytic bone lesions with mild erosive arthritis. The diagnosis of canine leishmaniasis was confirmed by bone biopsy and the detection of the pathogen by PCR. Three weeks after initiation of therapy with allopurinol, the dog presented no signs of lameness...

BACKGROUND: Detailed investigation of the vasculature of the lateral aspect of the foot has rarely been presented. However, harvesting the flap in this area to cover defects of the foot and hand is highly important. Repair of soft-tissue defects at the forefoot remains a challenge in reconstructive surgery. This study explores the characteristics of the distal-based lateral dorsal cutaneous neuro-lateral plantar venofasciocutaneous flap pedicled with the lateral plantar artery perforator of the fifth metatarsal bone to establish a repair procedure for ulcers or defects in the forefoot region...

PURPOSE: It has been the observation of the senior author that there is a bony fullness or "double medial malleolus" over the middle facet as a consistent finding with most talocalcaneal coalitions (TCC). To document this observation, we reviewed records and radiographs in 3 patient groups. METHODS: Part 1: retrospective chart review was completed for 111 feet to determine the clinical presence of a palpable "double medial malleolus." Part 2: computed tomography (CT) scans for evaluation of tarsal coalition or symptomatic flatfoot between January 2006 and December 2014 were retrospectively reviewed for the same cohort...

UNLABELLED: We report the case of a fungal mycetoma due to Madurella mycetomatis that failed to respond to surgery and antifungal treatment but responded strongly to the addition of a non-steroidal anti-inflammatory drug (NSAID). This African patient was born in Mauritania in 1972. He was a herdsman, living close to the Senegal River. The first nodules appeared on the left foot at the age of 13years (1985). The patient suffered frequent flare-ups with the appearance of black grains and underwent surgery in 1988 and 1992 in Senegal...

The hypotheses about the origin of the primitive amniotic tarsus are very speculative. Early studies argued that the origin of the astragalus, one of the largest proximal bones in the tarsus of basal amniotes, was produced by either the fusion of two, three, or even four of the original tarsal bones, the intermedium, the tibiale and the proximal centralia (c4 and c3), or that the intermedium alone transforms into the primitive astragalus. More recent studies have shown that the structure of the tarsus in Captorhinus supports the former hypothesis about a fusion of the intermedium, the tibiale, the proximal centrale (c4) and eventually c3, producing a purportedly multipartite structure of the amniotic astragalus, but the issue remained contentious...

Fractures of the tarsal navicular are commonly the result of trauma or chronic overload. Because of its complex anatomy and blood supply, the tarsal navicular is susceptible to osteonecrosis, and injury to this bone can lead to posttraumatic arthrosis of the surrounding joints. Diagnosis of the injury, especially in patients with stress fractures, can require a high index of suspicion and the use of advanced imaging. The treatment of stress fracture is controversial and ranges from immobilization in a non-weight-bearing cast or boot to internal fixation with or without bone grafting...
