Its treatment is based on complete surgical excision which ensures complete healing. The resumption of a tumor process raises two questions: is it a recurrence or a malignant transformation into chondrosarcoma? We report a case of a resumption of the tumor process of solitary exostosis of the lower metaphysis of the right radius in a 33-year-old patient. This recurrence occurred 10 years after the first surgery and was accompanied by signs of compression of the median nerve and a major bone remodeling raising fears of malignant transformation. But histological examination performed during the excision confirmed the benignity of this lesion. The long-term follow-up examination of 17 years found a patient in a good general condition with a satisfactory local condition. The malignant transformation of solitary exostosis is an exceptional event. Thus, faced with a resumption of the tumor process after excision of solitary exostosis, the inadequacy of the first excision remains the first diagnostic hypothesis.展开更多

It seriously compromises the function of the elbow. Objectives: To determine the epidemiological factors of this complication in order to prevent them and to assess the results of the therapeutic management. Material and method: This was a retrospective study that involved patients with olecranon pseudoarthrosis who were treated in the department between January 2006 and December 2016. The diagnosis of pseudoarthrosis was made at least 6 months after the management of the fracture. There were 16 men and 5 women. We analyzed the epidemiological factors, the treatment of pseudoarthrosis, and the postoperative outcome. Results: The incriminated factors were the complexity of the fracture line and the quality of treatment of the recent fracture. The osteosynthesis of pseudoarthrosis is similar to that of recent fractures. It requires in some cases a bone graft. The results of the treatment are satisfactory with 100% of consolidation, and a good functional result in 75% of the cases. Conclusion: The treatment of olecranon pseudoarthrosis is based above all on prevention by an optimal management of the recent fractures. The curative treatment gives satisfactory functional results.展开更多
