Exostoses or osteochondromas are benign osseous tumors that develop on the bone surface and can be sporadic or hereditary. Their evolution is generally benign but they may be complicated in some patients by conflicts with the surrounding nervous or vascular structures, in particular arteries. We report a case of false aneurysm of the popliteal artery secondary to an isolated exostosis of the left femur in a 20-year-old young woman. A delay in the diagnosis allowed the development of the false aneurysm which was at the origin of a major venous compression...

The foot and ankle specialist will frequently encounter patients with dorsal midfoot pain in clinic. In the presence of midfoot pain and/or paraesthesia, nerve entrapment must be considered. The authors report the outcome of a case series of patients who underwent surgical release of the DPN. Between 2011-2017, a single surgeon operated on seven patients with a diagnosis of DPN entrapment. A retrospective review of the patient's clinical notes was performed, including the operative findings. The average age at presentation was 47 years (range, 31-70 years), and the left foot was affected in four cases...

BACKGROUND: Subungual exostosis (SE) and subungual osteochondroma (SO) are an uncommon, benign tumor of the distal phalanx. The purpose of this retrospective study was to evaluate clinical, demographical, and radiological features; treatment modalities; and follow-up results in SE and SO cases. METHODS: Twenty-five cases were confirmed histopathologically as SE or SO. At the time of admission, clinical data were obtained on the age and sex of the patient, duration of symptoms, presence of pain, previous diagnoses and treatments, concomitant systemic diseases, family history, lesional localization, clinical and radiological features of the lesion, surgical treatment methods, and duration of follow-up...

REVIEW
G A Morawe, M H T Schmieschek
OBJECTIVE: Bunionette or 'tailor's bunion' is a deformity of the fifth ray, which comes along with a metatarsus quintus valgus and a varus deformity of the fifth toe with subluxation of the metatarsophalangeal joint. A minimally invasive osteotomy of the fifth metatarsal without internal fixation using burrs is an increasingly used alternative for symptomatic tailor's bunion deformity. Similar to open surgery procedures the type of osteotomy complies with the underlying pathology...

Lixuan Niu, Juan Wang, Huajie Yu, Lixin Qiu
BACKGROUND: It is complicated to select an appropriate sinus floor elevation and the procedure for sinus floor elevation lacks of consensus. Sinus contour plays an important role in choosing a surgery approach. But there are still no published articles revealing the influence of sinus contours to sinus floor elevation surgery. PURPOSE: We propose a new classification depending on sinus contours from cone-beam computed tomography (CBCT), analyze clinical characters of different types, and investigate the relationship between sinus contours and sinus floor elevation...

The elderly population is growing, lifespans are increasing, and a greater emphasis on geriatric care is being implemented in hospital systems. With a higher percentage of the population living longer, hair and nail diseases associated with the advanced stages of life are becoming more prevalent. Common hair diseases in the elderly include androgenetic alopecia, senile alopecia, frontal fibrosing alopecia, and erosive pustular dermatosis of the scalp. Nail diseases associated with advanced age include onychomycosis, brittle nails, onychocryptosis, onychoclavus, onychogryphosis, subungual hematomas, subungual exostosis, myxoid cysts, and malignancies...

Hereditary multiple osteochondroma (HMO) is an autosomal dominant genetic disorder characterized by multiple outgrowing bony tumors capped by cartilage, generally affecting the metaphyses. The disease is known as hereditary multiple exostoses, familial exostosis, multiple cartilaginous exostoses or hereditary malformation of cartilage. The prevalence of HMO in Europe and the Unites States is ~1:100,000, although it has not been reported in China. The disease is often accompanied by pain, asymmetry and skeletal malformations, including forearm and leg bending deformities, limb length discrepancies, and knee internal and external rotation abnormalities...

BACKGROUND: Subungual exostosis is a relatively uncommon, benign osteocartilaginous tumor of the distal phalanx of the toes or fingers in young adults, considered as a rare variant of osteochondroma. Differential diagnoses include subungual verruca (viral wart), pyogenic granuloma, osteochondroma, amelanotic subungual melanoma and glomus tumour. Misdiagnosis and total onychodystrophy frequently occur as a result of late treatment or inadequate treatment strategy. Dermoscopy could be a useful technique, involved in the diagnostic process, although X-ray examination and histopathology are mandatory for the diagnosis...

Osteochondroma and synovial chondromatosis are frequently reported benign bony and cartilaginous lesions. Osteochondroma is distinguished by a cartilage-capped bony exostosis on the exterior surface of the bone, whereas synovial chondromatosis is secondary to metaplasia and is characterized by multiple cartilaginous loose bodies within the synovium. We present an atypical case of synovial chondromatosis developing in a bursa sec-ondary to an underlying osteochondroma of the proximal medial tibia in a child...

Recently we reported the development of prominent exostosis young adults' skulls (41%; 10-31 mm) emanating from the external occipital protuberance (EOP). These findings contrast existing reports that large enthesophytes are not seen in young adults. Here we show that a combination sex, the degree of forward head protraction (FHP) and age predicted the presence of enlarged EOP (EEOP) (n = 1200, age 18-86). While being a male and increased FHP had a positive effect on prominent exostosis, paradoxically, increase in age was linked to a decrease in enthesophyte size...

OBJECTIVE To detect potential mutations of the EXT1 and EXT2 genes in a pedigree affected with hereditary multiple exostosis (HME). METHODS For a four-generation family with 7 affected individuals from 17 family members,genomic DNA was extracted from peripheral venous blood samples. All exons of the EXT1 and EXT2 genes were screened for potential mutation by PCR and Sanger sequencing. RESULTS A novel heterozygous frameshift mutation c.1202delT (p.I401Tfs*2)was found in exon 4 of the EXT1 gene in the proband and the other 6 affected individuals...

BACKGROUND: Exostoses at the base of the distal phalanx of the great toe are usually asymptomatic. The literature has not generally considered them as the origin of a possible problem resulting from a pressure conflict between hallux and shoe (medial aspect) or second toe (lateral aspect) nor a potential complication of surgical correction of hallux valgus deformity. No studies, to our knowledge, have evaluated its possible correlation with other foot disorders. When one of these neglected exostoses became painful after surgical correction of hallux valgus, we decided to start a study to determine their possible origin, prevalence in daily practice and histo-pathological morphology...

Metachondromatosis which was first described in 1971 by Maroteaux is a rare genetic disease consisting of osteochondromas and enchondromas, caused by loss of function of the PTPN11 gene. It is distinct from other cartilaginous tumors such as multiple osteochondromas and hereditary multiple exostosis by the distribution and orientation of lesions, and pattern of inheritance. In Metachondromatosis osteochondromas typically occur in hands, feet, femur, and tibia while enchondromas commonly affect the pelvic bones and femurs...

Osteochondroma or exostosis is the most common primary bone tumor containing both bone and cartilage. Soft tissue osteochondromas have been described at various locations, however, to the best of our knowledge, there is only a single case report of a soft tissue osteochondroma around the femoral neck. We, hereby report second such case. CASE REPORT: A forty year old female presented with swelling on medial aspect of left thigh since four years. Radiographs showed a large mass at the inferior surface of the left femoral neck...

When insertional Achilles tendinopathy is addressed surgically via a central-Achilles splitting approach, the calcaneal osteotomy has classically been performed from distal to proximal. We describe a simple proximal to distal technique that allows optimal resection of both the calcaneal exostosis and Achilles enthesophyte, minimizes risk to the soft tissues and skin, provides a bony attachment surface parallel to the axis of the Achilles tendon, and avoids the risk of osteotomy extension into the subtalar joint...
