... Abstract The forefoot cavus and hindfoot varus can be corrected by performing a closing wedge osteotomy at the base of the first metatarsal bone when the hindfoot is flexible. This is assessed with the Coleman block test. Indications Forefoot-driven cavo varus, rigid severe cavo...

... Abstract Osteotomies of the base of metatarsals as the Barouk-Rippstein-Toullec Osteotomy are a powerful tool to elevate and shorten the metatarsals. Due to the long lever arm, they have a high correction potential. They are indicated mainly for sagittal malpositions of the metatarsals...

... Abstract The anterior skull base can be divided into three segments: a midline and two symmetrically placed segments located laterally. The midline segment is the roof of the nasal cavity and serves as a watershed between the sinonasal tract and the intracranial space, whereas the lateral...

... Abstract The anterior skull base is a complex anatomic site which may be involved by a large number of biologically heterogenous neoplasms. They arise from the epithelium, both surface mucosa and glands, as well as soft tissues, bone, and cartilage. Many benign and malignant tumours...

... Abstract Treating malignant tumors of the anterior skull base (ASB) is a challenging task, given their late presentation, diverse histology, and involvement of an intricate anatomical space requiring complex surgery. Advances in imaging, gradual refinement of surgical and reconstruction...

... Abstract Anterior skull base tumors represent a challenge for radiation therapy (RT) planning given the close proximity of the target lesion to numerous critical structures in this complex anatomic location. Despite this challenge, surgery followed by postoperative RT is a common treatment...

... Abstract Benign tumors of the anterior cranial base may originate from intracranial, cranial, or extracranial sites. Intracranial tumors such as meningiomas may secondarily involve the cranial base and extend into the sinuses or nasal cavity. Bony tumors arising from the cranium include benign...

... Abstract Anterior skull base meningiomas are a diverse group of tumors that involve different locations. The role of the expanded endoscopic transnasal approach in the management of anterior cranial fossa meningiomas has significantly changed over the past 2 decades. Patient selection...

... and treatment challenges due to the proximity of the skull base and orbit. Survival in paediatric populations has improved steadily but in comparison adult RMS (over 35 years) have a poorer prognosis independently of the histologic subtype [ 28 ]. Sinonasal Epithelial Myoepithelial Carcinoma Epithelial...

... Abstract Malignancies of the anterior skull base are rare and recur in 40–80% of treated cases, varying with substantial variance according to histology, stage at primary diagnosis, and other factors. Most recurrences manifest within 2–5 years after primary treatment, but some histologies can...

... Abstract In the coming years, further developments can be expected in the field of diagnosis and management of tumors involving the anterior skull base, and especially malignant tumors of the sinonasal tract, which account for the majority of lesions affecting this anatomic area. Advances...

... Abstract Knowledge regarding epidemiology of injury is of benefit to injury prevention of activities associated with high risk. As relatively ‘young’ activities, the investigation of injuries and deaths related in extreme sports such as bungee jumping and BASE jumping is relatively sparse...
