A reexamination of the scierai ossicles of sceloporine iguanids was undertaken after conflicting data sets were discovered in the literature. The scierai ossicles of certain other iguanids were also studied for comparative purposes. Sceloporines exhibit much greater variation in ossicle configuration than has previously been reported. This variation is often too great within genera and species ...

The aim of the study was to describe ossicle resorption in chronic otitis with cholesteatoma and correlate it with clinical parameters such as age, contralateral ear condition, tympanic membrane aspect, cholesteatoma pathogenesis and extension, associated lesions and hearing threshold. Preoperative clinical data were collected for 140 patients with chronic otitis with cholesteatoma, whose ossic...

OBJECTIVE To describe and quantify growth patterns of cholesteatomas within the middle ear using a scaled rating system that characterizes patterns of ossicular erosion. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS Patients undergoing first-time surgery for primary and secondary acquired cholesteatomas. INTERVENTIONS Intraoperative assessments of os...

OBJECTIVE To investigate and analyze the relationship between individual ossicular erosion and air-bone gap (ABG) among patients with cholesteatoma. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. SUBJECTS AND METHODS Data from all patients undergoing an initial surgery for cholesteatoma were retrospectively reviewed to evaluate the relationships between preopera...

A 33-year-old woman presented with persistent right knee pain after an injury. Radiographs and magnetic resonance images were obtained.

--Dried scleral rings of Opisthocomus, Galliformes, Cuculiformes, and other birds were examined to determine the pattern of ossicle overlap in Opisthocomus and its bearing on the phylogenetic relationships of this taxon. Although Opisthocomus shares a derived number of 12 scleral ossicles with cuculid Cuculiformes, the pattern of ossicle overlap differs. Nevertheless, fewer modifications are re...

Introduction The ankle is characterised by long tendons with strong muscles. Tendon failure occurs due to overuse of the tendons as a result of repetitive contraction of the muscles. It also occurs because these tendons often pivot around a bony fulcrum or beneath a retinaculum, creating points of friction. The third area where ankle tendons fail is where they join to bone, either directly into...

Os peroneum is an accessory ossicle located within the peroneus longus tendon. The painful os peroneum syndrome (POPS) results from a wide spectrum of conditions, including fractures, diastases, and other causes. POPS can result in tenosynovitis or discontinuity of the peroneus longus tendon with a clinical presentation of pain in the lateral aspect of the midfoot. Authors report a typical case...
