INTRODUCTION Surgical excision of the ununited ossicles has been suggested for unresolved sequelae of Osgood-Schlatter disease in adults resistant to conservative measures. We report a case where arthroscopy was used to excise the ossicles. A bird eye view from the superolateral portal was helpful in the arthroscopic procedure for excision of the deep low lesion. CASE SERIES A 32-year-old, ma...

MPS VII mice are deficient in beta-glucuronidase and share many clinical, biochemical, and pathologic characteristics with human mucopolysaccharidosis type VII (MPS VII). We have shown that syngeneic bone marrow transplantation (BMT) prolongs survival and reduces lysosomal storage in many organs of the MPS VII mouse. In this report, we quantify the hearing loss and determine the impact of synge...

Globally, a body of comparative case-control studies suggests that rheumatoid arthritis (RA) patients are more prone to developing hearing loss (HL). However, experimental evidence that supports this hypothesis is still lacking because the human auditory organ is not readily accessible. The aim of this study was to determine the association between bone damage to the ossicles of the middle ear ...

Meniscal ossicles are rare entities of the knee usually involving the medial meniscus. Lateral meniscal ossicles are exceedingly rare. We present a case of a lateral meniscal ossicle found incidentally after trauma. The etiology and characteristic findings on imaging are discussed.

The bones of the middle ear are the smallest bones in the body and are among the most complicated functionally. They are located within the temporal bone – rendering them difficult to access and study. An accurate 3D model can offer an excellent illustration of the complex spatial relationships between the ossicles and the nerves and muscles with which they intertwine. The overall objective was...

•We examined scierai rings from 44 species of Pelecaniformes and found nonrandom variation in numbers of scierai ossicles among genera, but little or no variability within genera. Phaethon, Fregata, and Pelecanus retain the primitive 15 ossicles per ring, while the most recent common ancestor of the Sulae (Phalacrocoracidae, Anhinga, and Sulidae) is inferred to have had a derived reduction to 1...

Previous study of the ear ossicles in Primates has demonstrated that they vary on both functional and phylogenetic bases. Such studies have generally employed two-dimensional linear measurements rather than three-dimensional data. The availability of Ultra- high-resolution X-ray computed tomography (UhrCT) has made it possible to accurately image the ossicles so that broadly accepted methodolog...

Sesamoid ossicles are ovoid or round nodular small bones found usually within a joint or tendon of the upper and lower limb and rarely at other regions. They are usually asymptomatic, resulting in an increased propensity to injuries. We report on two cases where sesamoid ossicles were detected within the nuchal ligament. The first one was a 55-years-old Caucasian male office employee, complaini...

Accessory ossicles of the foot and ankle are normal variants of bone development that usually remain asymptomatic. However, they may be involved in various disorders and become a source of pain such as in fractures, dislocations, degenerative changes, osteonecrosis, osteoarthritis, osteochondral lesions, avascular necrosis, and irritation or impingement of adjacent soft tissues. Hence, during t...
