Introduction: Hemangiomas are the most common tumors of infancy and infantile hemangiomas are the most common vascular tumors. The etiology of this tumor is unknown. Hemangiomas commonly occur in the skin followed by the deep tissues (intramuscular) and rarely within bones. Case Presentation: Hereby, the case of a 6-month-old girl whose whole left lower limb f...

Terrestrial locomotion can impose substantial loads on vertebrate limbs. Previous studies have shown that limb bones from cursorial species of eutherian mammals experience high bending loads with minimal torsion, whereas the limb bones of non-avian reptiles (and amphibians) exhibit considerable torsion in addition to bending. It has been hypothesized that these differences in loading regime are...

Macrodactyly represents a rare congenital anomaly characterized by distal limb overgrowth of all tissue elements. This should be distinguished from secondary digital/limb enlargement that occurs in vascular anomalies or as a result of other syndromes. Macrodactyly is defined by an elargement of all the structures of fingers or toes and characterized by hypertrophy of the bones and surrounding s...

INTRODUCTION Angio-osteohypotrophic syndrome is also known as Servelle-Martorell angiodysplasia. It is characterized by venous or, rarely, arterial malformations, which may result in limb hypertrophy and bony hypoplasia. Extensive involvement of the upper limb is a rare feature of Servelle-Martorell syndrome. Cases with minimal upper limb involvement have been described in the literature. CAS...

How bones respond dynamically to mechanical loading through changes in shape and structure is poorly understood, particularly with respect to variations between bones. Structurally, cortical bones adapt in vivo to their mechanical environments primarily by modulating two processes, modeling and Haversian remodeling. Modeling, defined here as the addition of new bone, may occur in response to me...

Chondrosarcoma is a common malignant bone tumor, which accounts for 20% of all malignant bone tumors. It often occurs in the long bones, but the incidence of scapular chondrosarcoma is rare. Here, we describe a case of a large chondrosarcoma occurring in the scapula which was treated with Malawer limb salvage surgery. The patient retained considerable limb function after complete removal of the...
