概括
通过了解坐着时的圣骨机械力,可以减少柱状鼻手术的并发症. 上关节动脉穿孔器 (SGAP) 板有效地管理这些力量,从而取得成功的结果.
科学领域:
- 生物医学工程 生物医学工程
- 整形外科 整形外科 整形外科
- 伤口愈合 治愈 伤口愈合
背景情况:
- 柱状鼻治疗通常涉及切除和重建,但诸如伤口脱光,感染和复发等并发症是常见的.
- 了解姿势变化期间神经囊区域的机械力量对于优化柱状鼻手术中片选择至关重要.
研究的目的:
- 为了量化坐着和站立时对圣骨的机械力.
- 根据这些力量,评估SGAP (上关节动脉穿孔器) 适用于基于这些力量的柱状鼻重建的适用性.
主要方法:
- 从16名志愿者身上测量了皮肤拉伸,压力和剪切压力的测量,他们比较了坐着和站着的姿势.
- 用4x4厘米的方形网格评估皮肤拉伸,同时在六个十字点测量压力和剪切应力.
- 对10例用SGAP片治疗的柱状鼻病例进行了回顾性审查,以评估6个月后的结果.
主要成果:
- 坐着显著增加水平拉伸张力 (17.3%),并施加高压力 (106.6 mm Hg) 和剪切应力 (11.6 N) 在下部圣骨上.
- 在释放水平张力和减轻压力/剪切应力方面,SGAP 板表现出最佳性能,这是由于其皮下组织和血液流动造成的.
- SGAP 的捐赠部位位于高压下部圣骨区域的上方.
结论:
- 坐着会产生巨大的机械力对神经囊皮肤,有助于pilonidal鼻手术并发症.
- SGAP 是大型柱状鼻缺陷的有希望的重建选择,通过有效管理机械力来减少并发症.
- 在对用SGAP片治疗的患者的回顾性审查中没有报告任何并发症.

01:55Bone Structure
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:31Bone Remodeling and Repair
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
