Introduction Hereditary multiple exostosis (HME) is a skeletal disorder characterized by the presence of numerous bony outgrowths (osteochondromas or exostoses) that develop next to the growth plates of all the long bones (Solomon 1963). The most striking clinical feature of HME is the numerous cartilage-capped exostoses, which are associated with the entire skeleton. Skeletal surveys suggest t...

OBJECTIVE To determine (1) the prevalence of external auditory exostoses in a population of surfers and (2) the relationship between the length of time spent surfing and the prevalence, severity, and location of the exostoses. DESIGN Cross-sectional epidemiological study. SETTING General community. PATIENTS Three hundred seven avid surfers (93.5% males and 6.5% females; age distributions:...

A 38-year-old man with a known history of hereditary multiple exostoses and no history of trauma presented with a painful right femur mass. While the clinical presentation was concerning for malignant degeneration or a large overlying bursitis, the radiologic evaluation demonstrated a large fractured pedunculated osteochondroma with a thick cartilage cap and underlying bone marrow edema. Trauma...

Multiple cartilaginous exostoses (MCE) is one of the most common inherited skeletal disorders. A collection of 1124 cases was reported by Stock and Barrington (1925). Recently other large series have been published by Solomon (1963) and Sauer (1979). Different terms have been used for it such as multiple exostoses, hereditary multiple exostoses and diaphyseal aclasis. The swelling or "lump" are...

The aim of this paper is to report an exceptional case of multiple internal exostoses of the ribs in a young patient affected by multiple hereditary exostoses (MHE) coming to our observation for chest pain as the only symptom of an intra-thoracic localization. A 16 years old patient with familiar history of MHE came to our observation complaining a left-sided chest pain. This pain had increased...

INTRODUCTION Hereditary multiple cartilaginous exostoses is a syndrome characterised by the development of multiple osteochondromas. The diagnosis is typically made around the age of 12 years, and the prevalence is estimated at 1:50,000. During skeletal growth, the osteochondromas are benign, but in adult life malignant transformation into chondrosarcomas can occur. METHODS This study was a l...

Hereditary multiple exostoses (HME) is a skeletal disorder which primarily affects enchondral bone during growth. It is characterised by multiple exostoses, usually arising in the juxtaepiphyseal region of the long bones. Exostoses that affect "almost every bone in the body" were first mentioned by John Hunter in his Lectures on the principles of surgery in 1786.1 The first family affected by H...

We report the case of a 57-year-old male who presented with recurrent sinus infections and frequent nasal irrigation. He was found at nasal endoscopy to have multiple outgrowths along his ethmoid and maxillary sinuses. Computed tomography (CT) showed multiple bony exostoses along these sinuses. We report the imaging findings of exostoses associated with sinonasal irrigation.

To the authors' knowledge, few reports have been published in the English literature of using total knee arthroplasty and total hip arthroplasty for the treatment of hereditary multiple exostoses. This article describes 2 patients with hereditary multiple exostoses, 1 treated with total hip arthroplasty and 1 treated with total knee arthroplasty. Bony deformities make arthroplasty uniquely chal...
