| 9 | In fact, the healing process begins the moment the bone breaks. | 事实上,愈合过程从骨折开始. |
| 10 | Firstly, a blood clot forms around the fracture, | 首先 骨折周围形成血块 |
| 11 | helping stabilize the fracture site and causing swelling. | 帮助稳定断裂地点并引起肿胀. |
| 12 | Meanwhile, specialized white blood cells, including macrophages, | 同时,专门的白血球,包括巨噬细胞, |
| 13 | remove damaged tissue and prepare the area for repair. | 清除受损组织,为修复该地区做好准备. |
| 14 | Before applying a plaster cast, doctors examine the injury | 在施用石膏前,医生先检查伤口 |
| 15 | and use X-rays to assess the position of the fractured bone. | 并使用X光来评估骨折位置. |
| 16 | If the broken pieces are out of alignment, | 如果断裂的碎片脱离对齐, |
| 17 | the patient may first be given pain medication or sedation to improve comfort. | 患者可首先得到止痛药或镇静剂,以改善舒适。 |
| 18 | The doctor then carefully moves the bone fragments | 医生会小心移动骨头碎片 |
| 19 | back into their proper position in a procedure called a reduction. | 回到合适的位置 在一个叫做削减的程序。 |
| 20 | Once the bone is correctly aligned, the injured limb is wrapped in a protective layer | 一旦骨骼对齐,受伤的四肢被包裹在一个保护层中 |
| 21 | and covered with wet plaster bandages. | 并用湿的石膏绷带覆盖。 |
| 22 | These bandages can be molded to fit the body shape | 这些绷带可以模具来适应身体形状 |
| 23 | and gradually harden into a rigid cast that holds the bone in place during healing. | 并逐渐硬化成一个坚硬的铸造物,在愈合过程中将骨头固定在原位上. |
| 24 | The cast acts as a protective shell that keeps the broken bone from moving. | 铸造者起到保护性外壳的作用,使断骨无法移动. |
| 25 | Without it, everyday activities such as walking, writing or even sleeping | 没有它,日常的活动,比如走路,写作甚至睡觉 |
| 26 | could shift the bone fragments out of place. | 可能把骨头的碎片移开 |
| 27 | By holding the bone steady, the cast creates the stable conditions needed for healing. | 通过坚固的骨骼,铸件创造了治愈所需的稳定条件. |
| 28 | Within the next week or two, the reparative phase becomes the dominant stage of healing. | 在接下来的一周或两星期内,补偿阶段成为治疗的主要阶段. |
| 29 | Specialized cells called chondroblasts produce cartilage, | 专用的细胞叫做软骨 |
| 30 | forming a soft callus that bridges the gap between the broken ends of the bone. | 形成一个柔软的卡路里,可以弥合骨骼断裂端之间的缝隙. |
| 31 | This soft callus acts like a temporary scaffold, but it is still relatively weak. | 这种柔软的callus行为类似临时脚手架,但仍然相对薄弱. |
| 32 | Because the cast prevents excessive movement, | 因为铸件防止过度移动, |
| 33 | the soft callus can develop without being disturbed. | 柔软的卡卢斯可以发展而不受干扰. |
| 34 | Several weeks later, another group of cells called osteoblasts | 几周后,又一组细胞被称为"骨骼" |
| 35 | begins replacing the soft callus with a hard callus made of new bone tissue. | 开始用新的骨骼组织 制成的硬颈取代软颈 |
| 36 | These cells deposit minerals such as calcium and phosphorus into the developing bone, | 这些细胞将钙和磷等矿物沉积在发育中的骨骼中, |
| 37 | making it stronger and more rigid. | 让它更强大更僵硬 |
| 38 | Throughout this stage, the cast continues to protect the healing bone | 整个阶段, 铸件继续保护治愈骨骼 |
| 39 | from external forces that could interfere with recovery. | 可能干扰复原的外部力量。 |
| 40 | Once the fracture has healed sufficiently, the cast is removed | 一旦骨折完全愈合, 铸件就被移除 |
| 41 | using a special vibrating cast saw that cuts through the plaster without harming the skin. | 使用特殊的震动铸造的锯片,切穿石膏而不会伤害皮肤. |
| 42 | The procedure may feel unusual, but is typically painless and takes only a few minutes. | 手术可能感到异常,但一般无痛,只需要几分钟。 |
| 43 | Even after the cast comes off, healing continues through the remodeling phase. | 即使在铸件脱落后,愈合也持续到改造阶段. |
| 44 | Specialized cells called osteoclasts remove excess bone, | 专用细胞叫做骨质整流器 清除多余的骨头 |
| 45 | while osteoblasts continue to reshape and strengthen the repaired area. | 骨骼继续重塑和加强修复区域 |
| 46 | Over the following months, the bone gradually regains | 在接下来的几个月里,骨骼逐渐恢复 |
| 47 | much of its original shape, structure and strength. | 大部分的原始形状,结构和力量。 |
| 48 | For generations, plaster casts have been a reliable way to treat broken bones. | 历代以来,石膏铸造一直是治疗骨折的可靠方法. |
| 49 | Although newer materials such as fiberglass and waterproof casts are now available, | 虽然现在有了玻璃纤维和防水铸件等较新的材料, |
| 50 | the principle remains unchanged, providing protection and support | 原则保持不变,提供保护和支持; |
| 51 | so the body can repair the fracture naturally. | 所以身体可以自然修复骨折. |

| 53 | Did you know? | 你知道吗? |
| 54 | The name Plaster of Paris comes from the massive deposit of gypsum found in Montmartre, Paris. | 巴黎的普拉斯特(Plaster of Paris)这个名字来源于在巴黎蒙马特发现的大量石膏矿床. |
| 55 | 另外,在1851年,一位名叫Antonius Mathiasen的荷兰军医 | |
| 56 | realized that soaking linen bandages in plaster powder and water | 意识到在石膏粉和水中浸泡麻布绷带 |
| 57 | created a rigid fast-drying support system. | 创建了僵硬的快速干燥支持系统. |
