Fractures: Bone Repair01:27

Fractures: Bone Repair

3.7K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Classification of Bones

7.4K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Structural Classification of Joints01:20

Structural Classification of Joints

4.4K
Joints, also known as articulations, are classified based on their structural characteristics, i.e., based on whether the articulating surfaces of the adjacent bones are directly connected by fibrous connective tissue or cartilage, or whether the articulating surfaces contact each other within a fluid-filled joint cavity. These differences serve to divide the joints of the body into three structural classifications.
A fibrous joint is where the adjacent bones are united by fibrous connective...

概括

与最初的OTA-OFC相比,简化的骨科创伤协会-开放骨折分类 (OTA-OFC3) 并没有改善手术部位感染的预测,并恶化了未计划的重新手术的预测. 对于这两种结果,OTA-OFC3的表现与Gustilo-Anderson分类相似.

科学领域:

  • 整形外伤是指整形外伤的发生.
  • 手术部位感染的感染.
  • 断裂分类系统的破裂分类系统.

背景情况:

  • 骨科创伤协会开放骨折分类 (OTA-OFC) 是一个全面的系统来分类开放骨折.
  • 预测手术部位感染和重新手术等结果对于管理开口骨折至关重要.
  • 一个简化的版本,OTA-OFC3,被提议提高临床效用.

研究的目的:

  • 将简化的OTA-OFC3与原来的OTA-OFC和Gustilo-Anderson分类的预后性能进行比较.
  • 评估这些系统在预测手术部位感染和开放骨折患者计划外的重新手术方面的能力.

主要方法:

  • 一个回顾性队列研究,使用PREP-IT试验的数据.
  • 包括3338名患者,其中3627名患者有开放性骨折.
  • 使用接收器操作特征曲线 (AUC) 下面的面积来比较预测性能.

主要成果:

  • 11%的骨折发生了手术部位感染,15%的骨折发生了无计划的重新手术.
  • 对于预测手术部位感染,OTA-OFC3的性能与Gustilo-Anderson或原始的OTA-OFC没有显著差异.
  • 在预测未计划的重新操作方面,OTA-OFC3明显比原来的OTA-OFC差得多.

结论:

  • 将OTA-OFC简化为OTA-OFC3降低了对非计划性重新手术的预测能力,但没有改善手术部位感染预测.
  • OTA-OFC3可以提供一个临床上方便的沟通工具,但忽略了预后信息.
  • 它的性能可与Gustilo-Anderson分类相提并论,这是一个广泛使用的系统.
