Female, Hindoo, aged 40; not known to be hereditary; neither father nor mother, sisters, brothers, nor children, have the deformity. The thumb of the left hand was very broad, bulging out at the end of the first phalanx, and then narrowing to the root of the single normal nail. The metacarpal bone was single, but flattened at its distal extremity, and presented two articular surfaces, to which ...

Over the last two and a half decades, photoacoustic (PA) imaging has become an important area of research in biomedical optics. Combining high contrast optical with spatial resolution ultrasound (US) imaging, PA can simultaneously visualize anatomical structures while interrogating their functionality through multiwavelength spectroscopy. Alongside technological developments applications acoust...

The condition known as delta phalanx (or longitudinally bracketed epiphysis) is a rare congenital anomaly first described in 1964. The deformity consists of a triangular bone with an epiphysis running along the shortened side of the phalanx in a proximal to distal direction, making longitudinal growth of the digit impossible. Isolated hallux varus congenitus due to a delta phalanx of the proxim...

Bone age assessment using a hand radiograph is an important clinical tool in the area of paediatrics, especially in relation to endocrinological problems and growth disorders. This paper proposes Standard Deviation based skeletal Bone Age Assessment based on features extracted from phalanx. The system works according to the renowned Tanner and Whitehouse method based on the Phalanx Region of In...

triphalangeal thumb is characterized by the interposition of an extra-phalanx between two normal ones. in this article the authors present the case of a 24-year-old man with bilateral triphalangeal thumb of opposable type, without any other associated anomaly or genetic syndrome. the patient had triangular delta extra-phalanxes that caused ulnar deviation of both thumbs. surgical procedure for ...

Methods: We carried out measurements of bone mineral density (BMD) of lumbar spine and femoral neck using DXA, QUS of heel using ultrasound densitometer, and BMD of forearm using SXA. We performed all the measurements at the Nuclear Medicine Division of King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between 2002 and 2004. We obtained the measurements of 437 female adult patien...

The aim of this study was to evaluate phalangeal bone quantitative ultrasound (QUS) parameters in patients with Raynaud phenomenon (RP) and relate it with nailfold capillaroscopy findings. Patients referring to our Rheumatology Unit with RP were enrolled and studied for capillaroscopy alterations; bone quality profile was measured by QUS of the phalanxes: AD-SoS (Amplitude Dependent Speed of So...

BACKGROUND Sclerostin is an osteocyte-derived inhibitor of the Wnt/β-catenin signaling pathway, which acts as a negative regulator of bone formation. Published data on sclerostin levels in type 1 diabetes mellitus (T1DM) are few. OBJECTIVE To evaluate gender differences in sclerostin serum levels and the association among sclerostin, bone mass, bone metabolism, and the main clinical character...
