Abstract

Periprosthetic humerus fractures remain problematic complications that are difficult to adequately reduce and maintain reduction. Patient-related risk factors, including poor bone quality, add an additional level of complexity to maintaining fixation in the setting of relatively narrow cortical margins adjacent to the shoulder prosthesis. Based on the challenges of obtaining adequate proximal fixation and the need to minimize dependence on cerclage fixation because of nerve injury risks and inadequate fracture reduction, the authors propose an alternative method intraoperative fixation. The technique described is a method of fixation utilizing a small fragment instrumentation set for periprosthetic humerus fractures as demonstrated in a Sawbones model and intraoperatively in a patient-specific case.

肱骨假体周围骨折小碎片内固定技术
肱骨假体周围骨折仍然是难以充分复位和维持复位的并发症。患者相关的危险因素,包括较差的骨质量,增加了在肩关节假体附近相对狭窄的皮质边缘维持固定的复杂性。基于获得足够近端固定的挑战,以及由于神经损伤风险和骨折复位不充分而需要尽量减少对环扎固定的依赖,作者提出了一种术中固定的替代方法。所描述的技术是一种利用小碎片内固定装置固定肱骨假体周围骨折的方法,如Sawbones模型和术中特定病例所示。

期刊介绍: Published quarterly, Techniques in Shoulder & Elbow Surgery escorts the reader into the operating room and supplies step-by-step details of exciting and advanced techniques. It explains the evolution of and rationale for the procedures, identifies the pitfalls and possible complications, provides invaluable tips for improving surgical results and it is illustrated cover to cover with high-quality intraoperative photographs and drawings, many in full color.
