Patients and Method: Retrospective study including all patients diagnosed with mechanical complications after osteosynthesis of the limbs and who received medical follow-up. 42 patients with an average age of 42.2 years, with a male predominance (36 cases) were selected. These complications predominated in the femur with 26 cases. The implants involved were predominantly screwed plates with 25 cases. We investigated and analyzed the different types of dismantling of material as well as the etiological factors that may be at the origin of these disassembly. Results: After a mean follow-up of 15.47 months, four types of complications were identified: material expulsion (20 cases), migration (3 cases), incurvation (7 cases), fracture of material (12 cases). 4 types of factors causing dismantling have been identified: the factors related to the patient, factors related to fracture, the factors related to the implant and factors related to the surgeon. Conclusion: Disassembly of orthopedic implants is most often of multifactorial origin. These factors may act in isolation but are most often entangled in the patient. Proper preoperative planning can help prevent them. However, unexpected stresses of the implant and certain factors related to the ground remain difficult to control.展开更多
