We report a case of Klinefelter's syndrome owing to maternal meiotic error associated with triphalangeal thumb and delta phalanx bilaterally. There are no previous reports of similar cases and triphalangism with delta phalanx abnormalities of both thumbs might therefore be considered a further, but rare, manifestation of this aneuploidy.

An unusual Salter-Harris Type 1 fracture variant of the distal phalanx of the index finger is described. The epiphysis was dislocated, sitting dorsally over the middle phalanx head with the articular surface facing dorsal. Reduction could only be achieved through an open procedure. The reduction was stable without supplemental fixation.

Quantitative ultrasound (QUS) is a novel approach for characterizing tissue microstructure and changes in tissue microstructure due to therapy. In this report, we discuss changes in QUS parameters in liver tissues after being exposed to thermal insult. Effective scatterer diameter (ESD) and effective acoustic concentration (EAC) from the normalized backscattered power spectrum were examined in ...

Background: The aim of the study was to investigate the use of quantitative ultrasound (QUS) in the young (20-25years) Saudi females to obtain stiffness index values related to bone quality. Method & Findings: In 101 young females recruited, QUS measurements were performed in the calcaneus region. 33% and 3% had osteopenia and osteoporosis in the calcaneus respectively, stiffness index values =...

abstract a solitary plasmacytoma of bone occurs in approximately 2-5% of patients with myeloma. the lesion mostly found in the axial skeleton and have infrequently been reported to arise in the hand, and usually occur in the distal phalanges. we report the interesting case of a 75-year-old man who developed a solitary lytic lesion of the thumb proximal phalanx. this lesion was explored through ...

he Applied Physics Laboratory, in its role as Technical Direction Agent for the Phalanx close-in weapon system radar, designed and operates a coherent data collector to analyze radar system performance. This article presents examples of how coherent data analysis has helped program development efforts and provided insights into the performance of the Phalanx search radar. The topics discussed i...

A 2-day-old female Warmblood foal (70 kg) presented with a closed, displaced Salter-Harris type-II fracture of the proximal physis left hind first phalanx. The was repaired four 4.5 mm cortical screws and wire in figure-of-8 pattern applied on lateral medial aspect phalanx, respectively. screw additionally inserted lag-fashion to engage metaphyseal spike. Three days postoperatively, displacemen...

Evolutionary theory has long argued that the entrenched rules of development constrain the range of variations in a given form, but few empirical examples are known. Here we provide evidence for a very deeply conserved skeletal module constraining the morphology of the phalanges within a digit. We measured the sizes of phalanges within populations of two bird species and found that successive p...
