Images - Extra (too many) carpal bones in Larsen′s syndrome

Indian Journal of Radiology and Imaging, 2009
Multiple carpal bones may be seen in different syndromes, especially Larsen′s syndrome. A case of Larsen′s syndrome with many typical features and "too many" carpal bones, is described.

Atypical osteochondroma of the hamate that presented clinically as carpal tunnel syndrome: report of an extremely rare case and literature review

BMC Musculoskeletal Disorders, 2020
Background Osteochondroma is a benign tumor that occurs mainly at the metaphysis of long bones and seldom arises from carpal bones. We describe an extremely rare case of osteochondroma of the hamate without a typical cartilaginous cap and with a spiky ...

Scapho-luno-capitate fusion with proximal lunate articular surface preservation for management of grade IIIA Kienböck’s disease: a prospective case series

Journal of Orthopaedics and Traumatology, 2023
Background Kienböck’s disease is idiopathic lunate avascular necrosis, which may lead to lunate collapse, abnormal carpal motion and wrist arthritis.

Fractures of carpal bones other than scaphoid – a narrative review [PDF]

Chirurgia Narządów Ruchu i Ortopedia Polska
Fractures of the carpal bones are less common than fractures of the metacarpals and phalanges. The triquetrum and scaphoid are the most commonly affected bones, while injuries to other bones are less prevalent.

Early Holocene morphological variation in hunter-gatherer hands and feet [PDF]

PeerJ, 2018
Background The Windover mortuary pond dates to the Early Archaic period (6,800–5,200 years ago) and constitutes one of the earliest archaeological sites with intact and well-preserved human remains in North America.

Theoretical and experimental study of attenuation in cancellous bone [PDF]

Wenyi Xu, Weiya Xie, Dong Yu, Haohan Sun, Ying Gu, Xingliang Tao, Menglu Qian, Liming Cheng, Hao Wang, Qian Cheng, Theoretical and experimental study of attenuation in cancellous bone, J. Biomed. Opt. 29(S1), S11526 (2024), 2023
Photoacoustic (PA) technology can provide information on both the physical structure and chemical composition of bone, showing great potential in bone assessment. However, due to the complex composition and porous structure of cancellous bone, the PA signals generated and propagated in cancellous bone are complex and difficult to be directly used in ...

Accelerated Evolution of Limb-Related Gene Hoxd11 in the Common Ancestor of Cetaceans and Ruminants (Cetruminantia)

G3: Genes, Genomes, Genetics, 2020
Reduced numbers of carpal and tarsal bones (wrist and ankle joints) are extensively observed in the clade of Cetacea and Ruminantia (Cetruminantia). Homebox D11 (Hoxd11) is one of the important genes required for limb development in mammals. Mutations in

Evolution and identity of synapsid carpal bones [PDF]

Acta Palaeontologica Polonica, 2020
To date there is little information on carpal bone homology in late Palaeozoic and Mesozoic Synapsida. Crucial to the understanding of homology in synapsid carpal elements is the fact that different nomenclatures are used for the carpals of non ...

Skeletal age assessed by TW2 using 20-bone, carpal and RUS score systems: Intra-observer and inter-observer agreement among male pubertal soccer players.

PLoS ONE, 2022
The purpose of this study was to determine intra- and inter-observer agreement for the three skeletal ages derived from the TW2 method among male pubertal soccer players. The sample included 142 participants aged 11.0-15.3 years.

How many radiographs are needed to re-train a deep learning system for object detection? [PDF]

arXiv, 2022
Background: Object detection in radiograph computer vision has largely benefited from progress in deep convolutional neural networks and can, for example, annotate a radiograph with a box around a knee joint or intervertebral disc. Is deep learning capable of detect small (less than 1% of the image) in radiographs?
