In general surgical treatment of HMO includes one or more of the following procedures: ostechondroma excision, gradual or acute bone lengthening such as the ulna lengthening, corrective osteotomies, temporary hemiepiphysiodesis to correct angular joint deformities such as distal radius hemiepiphysiodesis and medial distal tibial hemiepiphysiodesis. It is one of the most common benign tumors of the axial skeleton. The medical . It can occur as a solitary lesion or as multiple exostoses associated with a hereditary condition known as Multiple Hereditary Exostoses (MHE) Radiation exposure can also be a cause of multiple osteochondromas. About 70-75% of multiple osteochondromas are caused by point mutations, often involving deletion of single or multiple axons as found in 10% of all hereditary cases. Osteochondroma is an overgrowth of cartilage and bone that happens at the end of the bone near the growth plate. We have evaluated the clinical outcomes of simple excision, ulnar lengthening and the Sauv-Kapandji procedure in the treatment of deformities of the forearm in patients with multiple hereditary osteochondromas. Hereditary multiple osteochondromas (HMO) is a rare genetic disorder characterized by multiple benign (noncancerous) bone tumors that are covered by cartilage . They represent 35% of the benign and 8% of all bone tumours, although this is probably an underestimation since the majority are asymptomatic. Treatment of multiple exostoses doesn't end with surgery and rehabilitative therapy however as there is still a risk of cancer, especially when the exostoses in adults is present in regions. Most often, it affects the long bones in the leg, the pelvis, or the shoulder blade. Limb-sparing wide local excision usually suffices. The multiple osteochondromas (exostoses) from which HME takes its name are for the most part benign outgrowths along the skeleton. Osteochondroma is the most common noncancerous bone growth. Surgical excision flush with the host bone is indicated if the lesion is painful, unsightly, producing disability or neurovascular compromise, or may be undergoing malignant change. Each osteochondroma has a very small risk of developing into a bone sarcoma (most often a chondrosarcoma, but less often it can be an osteosarcoma).
