The issue of metal release from stainless steel bone plates has gained considerable momentum advocating the removal of stainless steel miniplates after healing of fracture. So far no study has been published in the literature regarding metal release with the indigenously manufactured stainless steel miniplates.Objective Aim of the study was to find any pathological changes at cellular and ultracellular levels and metal particles in the soft tissue surrounding the stainless steel miniplates.Method Retrieval of indigenous stainless steel implants, used in treatment of jaw fractures, samples of surrounding soft tissue were histopathologically assessed for tissue response as well as metal release, using light microscope and Transmitted Electron Microscope (TEM).Result Light microscopic examination revealed chronic inflammation in symptomatic cases, but TEM did not show any significant pathological alteration and metal deposits even in cases with clinically observed pigmentation. Short-term (upto 1 year) retention of stainless steel mini plates will not cause any significant local complications.
不锈钢接骨板的金属释放问题已引起广泛关注，主张在骨折愈合后取出不锈钢微型接骨板。迄今为止，尚未有关于国产不锈钢微型接骨板金属释放的研究发表在文献中。本研究的目的是在细胞和超细胞水平上发现不锈钢微型接骨板周围软组织的任何病理变化以及金属颗粒。方法 检索用于治疗颌骨骨折的国产不锈钢植入物，使用光学显微镜和透射电子显微镜（TEM）对周围软组织样本进行组织病理学评估，以评估组织反应和金属释放情况。结果 光学显微镜检查显示有症状病例存在慢性炎症，但即使在临床观察到色素沉着的病例中，透射电子显微镜也未显示任何明显的病理改变和金属沉积。不锈钢微型接骨板短期（最长1年）留存不会引起任何明显的局部并发症。
