As a variably occurring sesamoid, the hallucal interphalangeal sesamoid can significantly alter the biomechanics of the great toe. With modifications to the way the great toe functions, there are pathologies that inevitably arise. These pathologies can be quite serious and debilitating. While clinicians may take a conservative approach to treatment and focus on alleviating the symptoms, the phy...

AIM The purpose of this study was to examine, with a sonographic investigation, the hand and wrist bones of a group of young patients and to compare the results with those obtained with a classical radiographic assessment. MATERIALS AND METHODS Some 25 subjects, 9-18 years of age, who presented problems concerning their short stature or precocious puberty, were evaluated. Each subject was exa...

Judging the strength of an argument may underlie many reasoning and decision-making tasks. In this article, we focus on "category-based" arguments, in which the premises and conclusion are of the form All members of C have property P, where C is a natural category. An example is "Dobermans have sesamoid bones. Therefore, German shepherds have sesamoid bones." The strength of such an argument is...

BACKGROUND The aims of this study were to identify risk factors for the recurrence of hallux valgus deformity and to clarify whether recurrence after surgery to treat hallux valgus can be predicted using radiographic parameters assessed on immediate postoperative non-weight-bearing radiographs. METHODS A proximal chevron osteotomy combined with a distal soft-tissue procedure was performed by ...

OBJECTIVE To estimate prevalences of various presale radiographic findings and of presale arthroscopy in horses offered for sale at the 2006 Keeneland September yearling sale and to compare sales prices between yearlings with and without various presale radiographic findings or a history of arthroscopy. ANIMALS 397 Thoroughbred yearlings. DESIGN Cross-sectional study. PROCEDURES Presale r...

Normal murine metapodophalangeal sesamoid bones, closely associated with tendons, were examined in terms of their structure and mineralization with reference to their potential function following crystal deposition. This study utilized radiography, whole mount staining, histology, and conventional electron microscopy to establish a maturation timeline of mineral formation in 1- to 6-week-old me...

INTRODUCTION Fractures of the sesamoid bones of the metacarpophalangeal joint (MCPJ) are a rare pathology in hand trauma. Only a few case reports and case series were found in literature. The diagnosis of an ulnar sesamoid bone fracture of the MCPJ is difficult and can pose a differential diagnostic problem with Stener lesions or ulnar collateral ligament (UCL) instability. This pathology is fr...

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...

The sesamoids are suspended by a sling like mechanism; sesamoid ligaments to the corresponding aspect of metatarsal head. There is no direct connection between sesamoids and flexor hallucis longus tendon that between them. The abductor hallucis and adductor hallucis tendons have fibrous insertions into the tibial and fibular sesamoids respectively. The deep transverse metatarsal ligament attach...

BACKGROUND Axial osteitis of the proximal sesamoid bones and desmitis of the intersesamoidean ligament has been described in Friesian horses as well as in other breeds. The objectives of this study were to review the outcome of clinical cases of this disease in Friesian horses and analyse the pathology of the bone-ligament interface. Case records of Friesian horses diagnosed with axial osteitis...
