概括
旋转袖口修复撕裂与中间侧面撕裂宽度和旋转袖口/三角形肌肉 (C/D) 比率有关. 在手术前和手术后,C/D比较高表明,在关节镜旋转手套修复后,纹风险增加.
科学领域:
- 整形外科手术 整形外科手术
- 运动医学 运动医学
- 生物医学工程 生物医学工程
背景情况:
- 旋转部撕裂是常见的伤害,通常用关节镜旋转部修复 (ARCR) 来治疗.
- 在ARCR之后的重复仍然是一个问题,需要确定预测因素.
- 桥方法是ARCR的一种常见技术.
研究的目的:
- 使用桥技术识别ARCR后复发的风险因素.
- 评估手术前和手术后肌状况与肌肉损伤之间的关联.
- 为了评估旋转手腕/三角形肌 (C/D) 关系的预测值,用于 retear.
主要方法:
- 对175名患者 (183个肩膀) 的回顾性分析,他们接受了中等旋转手套撕裂的ARCR.
- 在手术前对撕裂特征 (宽度,缩,脂肪退化) 和肌茎状况 (伊希塔尼分类,C/D比率) 的MRI评估.
- 在经过修复的袖口中对C/D比率的术后MRI评估;分类为修复 (Sugaya类型I-III) 和 retear (Sugaya类型IV-V) 组.
主要成果:
- 整体留学率为13.1%.
- 多变量分析确定了中间侧面撕裂宽度 (OR:0.88) 和C/D比 (OR:0.30) 作为重新撕裂的独立风险因素.
- 在术后,C/D比率在 retear 组显著更高 (1.70 与 0.84 相比,P = .002).
结论:
- 中侧侧面撕裂宽度和C/D比率是桥方法使用ARCR后再撕裂的重要风险因素.
- 在手术前和术后,C/D比率升高与复发的可能性更高有关.
- C/D比率作为一个有价值的指标,用于预测在旋转器袖口修复后的复发.

Structural Joints: Synovial Joints
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
Development of the Limb Synovial Joints
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Muscles of the Forearm that Move the Hand and Fingers
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 radialis,...

Angle of Twist - Elastic Range
Consider a cylindrical shaft with a length denoted by L and a consistent cross-sectional radius referred to as r. This shaft undergoes a torque at the free end. The highest shearing strain within the shaft is directly proportional to the twist angle and the radial distance from the shaft axis. When the shaft behaves elastically, this shearing strain can be articulated using variables such as the applied torque, radial distance, the polar moment of inertia, and the modulus of rigidity. By...
Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
