REVIEW
P-L Docquier, P Maldaque, M Bouchard
Tarsal coalition is due to failure of segmentation between two or more foot bones during embryological development at a site where the joint cleft fails to develop. Depending on the nature of the tissue connecting the bones, the abnormality is a syndesmosis, synchondrosis, or synostosis. Although the coalition exists at birth, synostosis usually develops only late during growth. Talo-calcaneal and calcaneo-navicular coalitions account for over 90% of all cases of tarsal coalition. The joint at the site of the coalition is stiff...

The location and/or type of variants in FLNB result in a spectrum of osteochondrodysplasias ranging from mild forms, like spondylocarpotarsal synostosis syndrome and Larsen syndrome, to severe perinatal lethal forms, such as atelosteogenesis I and III and Boomerang dysplasia. Spondylocarpotarsal synostosis syndrome is characterized by disproportionate short stature, vertebral anomalies and fusion of carpal and tarsal bones. Biallelic loss-of-function variants in FLNB are known to cause spondylocarpotarsal synostosis syndrome and nine families and nine pathogenic variants have been reported so far...

This study aimed to describe the radiographic anatomy and osteology and to evaluate angular radiographic measurements-Norberg angle, inclination angle and anteversion angle-of the pelvic limbs in free-ranging capybaras. Twenty cadavers of free-ranging capybaras (Hydrochoerus hydrochaeris), including five adults and 15 subadults, were studied. Ventrodorsal, craniocaudal, dorsoplantar and mediolateral radiographic views of the pelvic limbs were obtained. The radiographic features were described together with bone samples...

Background: The diagnosis of chronic exertional compartment syndrome can be challenging as other pathologies involving bone, muscle, nerve and vascular structures can mimic the syndrome. The purpose of this Fellow's Case Problem is to describe the clinical decision-making and physical therapy differential diagnosis regarding a 25-year-old patient with un-resolved neurovascular complaints following chronic exertional compartment syndrome surgical release. Diagnosis: After surgery, the patient's previous complaint of numbness and tingling in the plantar surfaces of her first and second toes of right foot was still present...

OBJECTIVES: Vibrational spectroscopy is a valuable tool for the study of burned skeletal remains. Nonetheless, most investigations have been focused on a limited number of samples as well as on faunal bones rather than human bones. Conclusions based on those investigations may lack representativeness, namely about the intrabone, intra- and interskeleton variability of several chemometric indices. We aimed to investigate this issue on a large sample of human bones. MATERIAL AND METHODS: Powder samples were collected from 168 bones from four human skeletons...

INTRODUCTION: Cuboid fractures are very rare. Hence, their treatment has not been standardized. Advances in imaging techniques, particularly three-dimensional computed tomography (3D CT), and the introduction of cuboid-specific plates has improved the care of these injuries. The aim of this study was to determine the radiological and clinical outcomes of anatomical reconstruction of comminuted cuboid fractures with a locking plate. HYPOTHESIS: Fixation of comminuted cuboid fractures with a cuboid-specific locking plate leads to stable anatomical reduction and good functional outcomes...

BACKGROUND AND AIM OF THE WORK: The calcaneus, the more lower bone of the body, has the task of supporting the axial load from the weight of the body. Calcaneal fractures represent about 1-2% of all fractures and 60% of the tarsal bones fractures. The articular involvement has been associated with a poor functional outcome. The aim of this work is to describe the radiologic evaluation, the classification systems, the morphological preoperative diagnostic imaging features of calcaneal fractures, highlighting the correlation with the choice of treatment and predictive capacity for the fracture surgical outcome...

REVIEW
E von Stillfried
Most deformities of the foot are visible at birth and can be diagnosed without imaging. They can be divided into congenital flexible, congenital structural and acquired foot deformities. The most common congenital flexible foot deformity in children is the metatarsus adductus, which usually requires no long-term therapy. Regarding congenital structural deformities, such as the clubfoot and talus verticalis, plaster therapy should be started during the first week of life, so that by the end of the first year of life and the beginning of the verticalization, a pain-free resilient foot with normal function is present...

In very fragmentary remains, the thorough inventory of skeletal elements is often impossible to accomplish. Mass has been used instead to assess the completeness of the skeleton. Two different mass-based methods of assessing skeleton completeness were tested on a sample of experimentally burned skeletons with the objective of determining which of them is more reliable. The first method was based on a simple comparison of the mass of each individual skeleton with previously published mass references. The second method was based on mass linear regressions from individual bones to estimate complete skeleton mass...

The bone SPECT/CT allows for precise anatomic delineation of bone activity, which can be valuable for diagnosis of nonmalignant bone diseases. We report an extremely rare case of sphenoid sinus aspergillosis, observed on bone SPECT/CT imaging, as an isolated disease in an immunocompetent individual. A 58-year-old woman with a history of plantar fasciitis was assessed for infection in the tarsal bones. Planar bone scan image revealed incidental focal lesion in skull base, which was considered to be the left sphenoid sinusitis by the bone SPECT/CT scan...

REVIEW

Clear definitions of 'normal' equine gestation length (GL) are elusive, with GL being subject to a considerable number of internal and external variables that have confounded interpretation and estimation of GL for over 50 years. Consequently, the mean GL of 340 days first established by Rossdale in 1967 for Thoroughbred horses in northern Europe continues to be the benchmark value referenced by veterinarians, breeders and researchers worldwide. Application of a 95% confidence limit to reported GL range values indicates a possible connection between geographic location and GL...

There are no accepted methods to grade bone marrow oedema (BMO) and fracture on magnetic resonance imaging (MRI) scans in Charcot osteoarthropathy. The aim was to devise semiquantitative BMO and fracture scores on foot and ankle MRI scans in diabetic patients with active osteoarthropathy and to assess the agreement in using these scores. Three radiologists assessed 45 scans (Siemens Avanto 1.5T, dedicated foot and ankle coil) and scored independently twenty-two bones (proximal phalanges, medial and lateral sesamoids, metatarsals, tarsals, distal tibial plafond, and medial and lateral malleoli) for BMO (0-no oedema, 1-oedema < 50% of bone volume, and 2-oedema > 50% of bone volume) and fracture (0-no fracture, 1-fracture, and 2-collapse/fragmentation)...

In recent years, some authors have reported accessory anterolateral talar facet impingement with flatfoot including peroneal spastic flatfoot. Conversely, to our knowledge, no case report has been published about accessory anterolateral talar facet impingement with tibialis spastic varus foot. We report the first case in a 22-year-old man with intellectual disability, bilateral cleft hands and type 1 diabetes mellitus. Since spraining his left ankle over a year earlier, he experienced left sinus tarsi pain while standing and walking...

The talus secundarius is one of the rarest accessory tarsal bones, being present in 0.01% of all ankles. It is located at the lateral side of the talus, distally to the tip of the fibula. Hitherto, only five cases of a symptomatic talus secundarius have been described in literature. We presented a case of bilateral symptomatic talus secundarius in a young gymnast. There was a difference in size of the two accessory bones. The large talus secundarius in the left ankle was fixated, in the right ankle the fragment was excised...

The in vivo kinematic characteristics of the tarsal joints during gait stance phase were still unclear in adult-acquired foot deformity (AAFD). This study included seven healthy subjects (fourteen feet) and twelve stage II AAFD patients (fourteen feet). The 3D models of tarsal bones were reconstructed based on CT scan. Each subject took standard gait on the single fluoroscopy system. Continuous lateral fluoroscopic images were collected. The key postures during the stance phase were selected. The 2D-3D registration technique was applied to explore the spatial motions of the tarsal joints in 6 degrees of freedom (DOF)...

A mutation in GDF6 was recently found to underlie a multiple synostoses syndrome. In this report, we describe the second family with GDF6-related multiple synostoses syndrome (SYNS4), caused by a novel c.1287C>A/p.Ser429Arg mutation in GDF6. In addition to synostoses of carpal and/or tarsal bones, at least 6 of 10 affected patients in this family have been diagnosed with mild to moderate hearing loss. In four of them otosclerosis was said to be present, one patient had hearing loss due to severe stapes fixation at the age of 6 years, providing evidence that hearing loss in the GDF6-related multiple synostoses syndrome can be present in childhood...
