Fracture shaft humerus when surgically fixed is known to go into non-union and one of the main reasons of this is implant failure. The causes of implant failure may lie in the fracture personality, faulty implant material or choice, dubious surgical technique & faulty mechanics of fixation. Implants may break and cut-through but a unique type of implant migration from one surgical compartment to the other or one anatomical part of body to the other has not been hitherto reported. A 45-year-old male, farmer by occupation, was operated for fracture shaft of humerus 15 years back. He presented to us because of pain due to subcutaneous presence of plate in forearm. X-ray of the elbow with forearm showed that the plate used for fixation of humerus had migrated from one body part to another that is from arm to forearm. The patient on deliberation regarding the pros and cons of surgical treatment options, chose not to get his humerus non-union resolved surgically. This was because he could do his activities related to farming reasonably well.
肱骨干骨折手术固定后已知会出现骨不连，其主要原因之一是植入物失败。植入物失败的原因可能在于骨折特性、有缺陷的植入物材料或选择、可疑的手术技术以及固定力学问题。植入物可能会断裂和穿透，但迄今为止尚未有从一个手术腔室迁移到另一个手术腔室或从身体的一个解剖部位迁移到另一个解剖部位的独特类型的植入物迁移的报道。一名45岁男性，职业为农民，15年前因肱骨干骨折接受手术。他因前臂皮下钢板引起的疼痛前来就诊。肘部及前臂的X线检查显示，用于固定肱骨的钢板已从身体的一个部位迁移到另一个部位，即从手臂迁移到了前臂。在权衡手术治疗方案的利弊后，患者选择不通过手术解决肱骨骨不连问题。这是因为他能够较好地进行与农活相关的活动。
