Congenital Hand
Published in J. Terrence Jose Jerome, Clinical Examination of the Hand, 2022
Osteochondromas grow from the physes of long bones, the pelvis, ribs, scapula or vertebrae. Forearm osteochondromas frequently cause a discrepancy in length of the radius and ulna [46]. Early removal of osteochondroma may retard or prevent progressive growth disturbance [47,48]. Ulnar lengthening may be performed in a single stage or by gradual distraction osteogenesis [32].

A 27 year old male presents with a firm lump arising around the left elbow. Elbow radiographs demonstrate a pedunculated bony outgrowth from the humerus consisting of the cortex and medulla. MRI confirms the presence of a cartilage cap. The most likely diagnosis is considered to be a benign osteochondroma.

As shown in the family tree (Figure 1), the patient was a member of family greatly affected by multiple osteochondromas. The possibility of genetic testing for hereditary multiple exostosis, also called multiple osteochondromatosis, was pursued. Individuals with HME often develop benign cartilage-capped tumor (exostoses) at the ends of the long bones or the surface of flat bones (Zak, 2002). HME usually presents early in life with 80% of patients diagnosed before the age of 10. Bony deformity, bowing of the long bones, limited range of motion, and premature osteoartrosis may be associated with HME. A commonly benign condition, its prevalence is estimated at 1 in 50,000. A rare but severe risk in patients with multiple exostoses is the development of malignant chondrosarcoma, which occurs in 1–2% of patients.

An osteochondroma, also known as an osteocartilaginous exostosis, is an osseous stalk that is continuous with the underlying bone via a cartilaginous cap. It is a common benign bone tumor, and most of the time occurring as a solitary lesion [7,8]. Because most of the osteochondromas are asymptomatic, the exact incidence is unknown [7]. They usually develop on the metaphyseal part of long bones of the limbs, and are often turned away from the joint. The distal femur, proximal humerus and the proximal tibia are most frequently involved [7,9]. Soft tissue surrounding an exostosis may be able to move without inducing pain due to a bursa that may develop around well-developed tumors [9]. An osteochondroma may become symptomatic due to a growing volume or after trauma causing a fracture [7,9,10]. Occasionally, symptoms may arise from pressuring muscles, tendons or vascular structures [8]. Compression of a nerve is extremely rare, occurring in <1% [10]. We are not aware of other cases of tibial nerve entrapment in the soleal tunnel due to an osteochondroma. Malignant transformation occurs in approximately 1% in clinically recognized osteochondromas [7,10].
Hereditary multiple exostoses: are there new plausible treatment strategies?
Published in Expert Opinion on Orphan Drugs, 2018
HME, also known as Multiple Osteochondromas (MO), is a rare congenital pediatric disorder characterized by benign tumors called exostoses or osteochondromas that form next to the growth plates in ribs, long bones, vertebrae, and other skeletal sites in young patients [1,2]. The osteochondromas are initially cartilaginous but, with time, undergo endochondral ossification in their proximal region and connect to the adjacent osseous elements. Because of their large number and location, osteochondromas can cause a variety of health problems that include skeletal deformities, growth retardation, chronic pain, and impingement of nerves, vessels, and muscles [3]. Surgery is currently used to remove the most symptomatic osteochondromas and alleviate and correct physical problems [3]. However, because of their number and difficult anatomical location, many osteochondromas are left in place, causing life-long problems and increasing the probability of malignant transformation into chondrosarcomas [4]. At present, there is no treatment to prevent, reduce, or reverse the formation of osteochondromas [5,6].

Solitary osteochondroma is a benign tumour affecting mainly children and adolescent with a peak incidence around 12 years of age. Fifty percent are diagnosed before the age of 20 [1]. Osteochondromas originate from the metaphysis of long bones and represent 8.5% of bone tumours and 36% of benign bone tumours [1,2]. The most common complications of distal femoral osteochondromas are of vascular or nervous origin [3]. We report the case of an 11-year-old boy with a false aneurysm of the popliteal artery due to an osteochondroma of the distal femur, with atypical clinical presentation.
