当第一次学习此协议，确定在哪里可以找到最初的切口可以是具有挑战性。然而，在小鼠安乐死的做法可以帮助外科医生学会在哪里放置初始切口，暴露所需的肋骨被切除。工作在尸体也提高到具有或不具有骨膜除去肋部分所需的精细运动技能。此外，新的人到该过程可能会发现操纵细的工具和薄缝线是困难的。而打结，多余的拉动缝线可以撕裂组织。因此，一些实践缝合也对尸体可能是有帮助?...

衰弱的骨骼损伤，慢性骨关节炎，以及与重建手术相关的严重问题影响经济生产力，家庭幸福，和生活质量。而小断裂和损伤可以治愈还算不错，人类是不能修复大的缺陷，因此必须依靠重建手术，恢复的结构和功能。重建可能涉及同种异体或heterogeneic移植，骨morcellized，植入支架，或牵张成骨。不幸的是，不仅有与这些处理，但在修复骨骼的原始强度是很少获得持久性相关的发病率的因素。因此，需要新的临床方法。 单向开发创新的方法来治疗节段性缺损的研究中，大型维修时，自然的情况。著名的两栖动物可以再生骨骼元素，而哺乳动物被认为是有限的日是能力。然而，由于20 世纪初期，再生在人肋几个报告已经发表表明人类可能不被如此限制1-4。目前这种现象，最好由整形外科医生谁使用肋材料颚，脸和耳重建已知的，但它不是更广泛地理解5。为了研究这种修复中更详细地说，我们已经开发出使用鼠标的外科模型。使用该协议，研究人员可以识别所涉及的先天因素，并使用该信息，以便在其它地点的骨骼的愈合。 有许多优势，使用肋骨作为模型来研究骨骼修复。首先，将周围的肋提供自然固定器（相对于切除股骨6,7）。这降低了内部和外部固定器的发病风险并简化了外科手术。胸部西澳其次，薄肌层会提供易于访问和良好的能见度使得检测媲美颅骨切除8的便利。第三，在对比其通过膜内骨化，由软骨内骨化肋形式形成，并通过延伸在位于中央骨干的任一端生长板生长长度的颅骨。因此，修复肋可能更媲美修复长骨的阑尾骨架组成。此外，我们已经发现，相对于股骨，肋的骨膜较厚，可以更容易地操纵。因此，调查谁愿意测定骨修复的研究骨膜或测试细胞疗法，药物制剂，和/或组织支架的目的，可能会发现这种手术模式非常有用。总之，这个肋切除模型提供在其内来研究天然大型骨修复哺乳动物中一般使用没有这样的模型当前存在的上下文。

a surgical procedure for resecting the mouse rib: a model for large-scale long bone repair

该协议研究人员介绍，为大规模的骨修复利用鼠标肋骨的新模式。该过程详细描述了以下内容：准备动物进行手术的，打开胸体壁，从周围肋间肌曝光所需的肋，切除肋的所需部分，而不诱导气胸，并关闭所述切口。相较于四肢骨骼的骨头，肋骨都非常方便。此外，没有任何的内部或外部固定器是必要的，因为在相邻的肋提供自然的固定。手术采用市售的用品，很简单易学，且耐受性良好的动物。该过程可以进行具有或不具有除去周围骨膜，因此骨膜修复的贡献可以被评估。结果表明，如果被保留的骨膜，鲁棒修复发生在1 - 2个月。我们希望利用这个协议会鼓励研究到肋骨修复，而结果将有利于新的方式来刺激骨修复等身体周围地区的发展。

动物通常此过程中快速恢复，切口愈合良好，动物表现出正常的行为。该过程使用市售的用品和实践后，可在1小时内完成的。使用此过程来产生的实验数据前，有必要分析切除在第0天时间点，以确定是否有任何大的骨碎片可能会保留在切除区域内是重要的。评估适当的程序的一种方法是，以评估动物用X射线或显微成像术后，尽管这通常需要特别的辐射的安全认证。相反，另一种简单的评估可以?...
