背景:
- ダイナミック・コンプレッション・プレート (DCP) や ロッキング・コンプレッション・プレート (LCP) のような伝統的な骨折固定方法には限界があります.
- 骨折の治癒を向上させるために バイオメカニカル性能を向上させるための新しいインプラントの設計を 評価することが重要です
- 断片間の圧縮は 安定した骨結合を達成する上で 重要な要素です
研究 の 目的:
- ダイナミック・コンプレッション・アングル・ステーブル・インターロッキング・ナイル (DCASIN) によって生成される断片間圧縮力を,既知の DCP と LCP システムと比較する.
- 横断骨折モデルでDCASINの生体力学的有効性を評価する.
- DCASINが従来の固定方法と同等またはより優れた圧縮力を提供するかどうかを判断する.
主な方法:
- 横断骨折をシミュレートするために,合成横断骨模型 (SDBM) を利用した.
- G-DCASIN,G-DCP,およびG-LCPの3つの固定群を使用し,それぞれ10回の繰り返しを行いました.
- 特定の圧縮技術を適用した後,骨折の隙間に位置したストレージ・ゲージ・ロード・セルを使用して圧縮力を測定します.
主要な成果:
- DCASINは平均圧縮力を22. 56 ±5. 1kgにしました.
- DCPは平均圧縮力 27.28 ± 1.86 kgを達成しました.
- LCPは11.65 ± 1.69kgの平均圧縮力を有意に低下させた. DCASINとDCPは,LCPよりも著しく高い圧縮を示した (p < 0. 0013).
結論:
- DCASINは,LCPよりも優れた,そしてDCPに匹敵する断片間圧縮を生成する能力を示した.
- 角度安定のロックと圧縮能力の組み合わせにより,DCASINは横断骨の骨折の潜在的な代替品となります.
- 骨格外傷治療におけるDCASINの有効性を確認するために,さらなる臨床評価が必要である.

Frictional Forces on Screws
1.3K
Screws are characterized by a helical ridge known as a thread wrapped around a cylindrical shaft. They are commonly used as fasteners to hold objects together or to transmit power and motion in machines. One type of screw that is particularly useful for transmitting power is the square-threaded screw.
A jack with a square-threaded screw is a mechanical device used to lift heavy loads by applying a force at its handle. When the force is applied, the screw turns, raising the load. The screw can...

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
The toggle clamp system is a machine structure consisting of movable, pin-connected multi-force members that form a stabilized system to transmit forces. The...

Behavior of Concrete Under Compressive Load
267
Concrete exhibits specific behaviors under different compressive loads. Understanding this is crucial for understanding its structural integrity. When concrete undergoes uniaxial compression, it tends to develop cracks that run parallel to the direction of the force. These parallel cracks stem from localized tensile stresses that occur perpendicular to the compression direction. Additionally, angled cracks may appear due to the formation of shear planes.

Wedges
1.2K
A wedge is a simple machine that serves various purposes, such as adjusting the elevation of structural or mechanical parts, providing stability for heavy objects, and splitting a body into two parts. This versatile tool can amplify an applied force, making it easier to manipulate large or heavy objects.
Consider using a wedge to lift a heavy slab. Here, the wedge functions by converting the applied force into a much larger force directed almost perpendicular to the initial force. This...

In wood construction, fasteners are essential for securing components together, with the connection strength largely dependent on the direct bearing between members. Various types of fasteners are employed, each suited to specific applications and structural requirements.
Nails are the most common fasteners, consisting of sharp-pointed metal pins that are driven into wood using a hammer or a mechanical nail gun. They come in a variety of diameters, heads, and lengths. Nailing techniques include...

Self-Locking Screw
1.7K
A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.
