Introduction and Objectives: Osteochondroma is the most common tumour of the bone. Treatment is necessary only in the case of pain, compression of adjacent structures, for aesthetic reasons, or in cases of suspected malignancy. Materials and Methods: This study reviews a series of 119 patients with solitary osteochondroma tracked in our centre since 1975. Location, gender, reason for consultation, tumour and treatment-related complications, type of treatment, recurrence and malignant transformation, and final status of patients were tracked for a minimum of one year. Results: Of the 119 patients in this study, 75 required surgical intervention, with tumor recurrence being the most common complication (15 cases). Seven patients suffered malignant transformation all of which resolved after surgical intervention. Discussion and Conclusions: In our experience, simple resection is a satisfactory treatment for osteochon-droma in most cases. Periodic follow-up is necessary in these cases as they have the potential to become malignant

Aim: This study describes the clinical features and treatment of 94 patients with skeletal osteochondroma during the last 20 years. Materials-methods: A retrospective review of various size solitary osteochondroma was evaluated. There were 51 males and 44 females with mean age 21 years. The mean follow-up was 8 years (1–12). There were 40 lesions in the distal femur, 6 in the greater trochanter, 19 in the proximal tibia, 1 in the proximal fibula, 1 in the calcaneus, 3 in the lateral malleolus, 1 in the medial malleolus, 3 in the talus, 2 in the tarsus, 3 in the metatarsals, 3 in the scapula, 4 in the humerus, 1 in the elbow,1 in the radius, 6 in the fingers. The lesions were diagnosed by history and plain radiographs. In two patients with large lesions around the knee an angiography was done. Results: Pain and local tenderness were the main symptoms. The treatment was en bloc excision of the tumor. There were no recurrence. Two patients had wound infection which was dealt with antibiotic. Conclusion: The site and the results of this study are similar with the literature. The radiologic image is pathognomic for the tumor. The treatment consisted of en bloc excision. There is high possibility of recurrence in case of insufficient excision

Aim: A case report: Symptomatic Osteochondroma of the Coracoid. Introduction: An osteochondroma is a common developmental tumour of bone characterized by abnormal periphyseal ectopic endochondral ossification. This results in a cartilage-capped subperiosteal bony projection. A solitary osteochondroma is encountered more frequently than are multiple hereditary osteochondromas. They are usually appreciated in the first decades of life and are most commonly located in the long bones, especially the femur, humerus and the tibia. Clinical presentations generally relate to the mass effect of the lesion. These lesions are said to grow to skeletal maturity. Continuous slow growth of the osteochondroma in adults should alert the clinician to the possibility of secondary malignant transformation, usually to a chondroma. Method: We present an unusual case of shoulder pain in a 36-year-old man with a painful solitary osteochondroma of the coracoid process. Plain radiographs, computed tomographic and magnetic resonance imaging of the lesion showed a solitary osteochondroma with a visible cartilage cap eroding the under surface of the clavicle. The lesion was surgically explored and excised. Histological examination showed a benign osteochondroma. Removal of the tumour resulted in resolution of all signs and symptoms. Conclusion: We are aware of no reported cases in the literature of osteochondroma of the coracoid process. This case was unusual in terms of age at clinical presentation and location, suggesting a continuous growth of the tumour beyond skeletal maturity

Our aim was to investigate the outcome of excision of osteochondromas. Between 1994 and 1998, 92 symptomatic osteochondromas in 86 patients were excised. There were 40 women and 46 men with a mean age of 20 years (3 to 62). Of these, 56 had a solitary osteochondroma and 30 had multiple hereditary tumours. The presenting symptoms were pain (79.1%), swelling (23.3%), reduced range of movement (19.8%), cosmetic abnormalities (17.4%), and bursitis (12.8%). The most common site (37.6%) was around the knee. Four patients had major complications (4.7%) including one intra-operative fracture of the femoral neck and three nerve palsies which resolved after decompression. Six patients had minor complications. Overall, 93.4% of the preoperative symptoms resolved after excision of the tumours. Excision is a successful form of treatment for symptomatic osteochondromas with a low morbidity

Aims

Chondrosarcoma is the second most common primary sarcoma of bone: conventional chondrosarcoma accounts for 85% of all cases. Conventional chondrosarcoma may be central or peripheral. Most studies group central and peripheral chondrosarcomas together, although there is growing evidence that their clinical behaviour and prognosis differ. The aims of this study were to analyze any differences in characteristics between central and peripheral chondrosarcomas and to investigate the incidence and role of different syndromes.

Aims

The aim of this study was to report the outcomes of patients who underwent definitive surgery for secondary chondrosarcomas arising from osteochondromas.

Aims

We report a prospective cohort study of the midterm results of surgical dislocation of the hip (according to Ganz) to perform resection of osteochondromas involving the femoral neck in patients with multiple hereditary exostoses (MHE).

We report a case of vertebral osteochondroma of C1 causing cord compression and myelopathy in a patient with hereditary multiple exostosis. We highlight the importance of early diagnosis and the appropriate surgery in order to obtain a satisfactory outcome.
