- 有效的手术修复对于恢复关节稳定性和功能至关重要.
- 目前的修复方法各不相同,需要对它们的生物力学特性进行比较分析.
研究的目的:
- 为了比较N方法的接强度与使用接的简单接,用于近接间关节附带带修复.
- 在尸体模型中评估不同附带带修复技术的生物力学性能.
主要方法:
- 使用72个新鲜冷的尸体手指进行机械测试.
- 实验1:评估破裂强度和完整的附带带的破裂部位.
- 实验2:比较N方法 (三个锁定) 与简单 (S组) 的破裂强度和故障模式.
- 实验3:比较N方法之间的断裂强度和故障模式,使用三个 (N3) 和两个 (N2) 锁定.
主要成果:
- 完整的附带带的平均破裂强度为80.6 ± 27.5N,近位撕裂是最常见的.
- N方法 (46.3 ± 19.2 N) 显示的破裂强度明显高于S组 (24.1 ± 12.7 N).

01:03Structural Joints: Fibrous Joints
1.9K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

01:22Sutures of the Skull
6.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:17Muscles of the Forearm that Move the Hand and Fingers
881
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...
