概括
合并多个tarsometatarsal (TMT) 关节需要更长的时间来治愈X射线,但与单关节合并相比,最终结合率相似. 植入物和移植的选择显著影响TMT融合的成功.
科学领域:
- 整形外科手术 整形外科手术
- 脚和脚重建 脚和脚重建
- 关节切除技术的技术.
背景情况:
- 斜甲足关节 (TMT) 关节节位治疗对于严重的头变形,中脚创伤和骨关节炎至关重要.
- 合并的TMT关节数量对工会率的影响尚未得到充分证实.
- 现有的文献缺乏对TMT融合结果的固定方法和骨移植进行全面的比较.
研究的目的:
- 为了确定多个TMT关节的融合是否会影响关节切除关节的结合率.
- 为了比较TMT融合中不同固定结构和骨移植技术的结合结果.
- 分析接接头数量对放射性结合时间的影响.
主要方法:
- 对582个TMT融合进行了回顾性队列研究.
- 单关节和多关节融合进行了比较,重点是中间和中央柱.
- 经过奖学金培训的足外科医生对放射和CT扫描进行了评估,以评估8周和12周的结合,并注意到固定和移植类型.
主要成果:
- 单个TMT联合合并显示了12周早结合比例更高 (74.9%),而不是多个联合合并 (67.0%).
- 最终的合并率相似:单合并的合并率为80.3%,多合并的合并率为82.6%.
- 在第二个和第三个TMT关节中,主固定具有较高的非联合率,而螺丝固定在第一个TMT关节中显示出最高的非联合率. 合并的螺丝和板显示了最低的非工会率.
结论:
- 虽然放射性非联合率 (18.2%) 比以前报告的更高,但症状性非联合很少 (4.6%).
- 与单个关节的融合相比,多个TMT关节的融合需要更长的时间来实现射线统一.
- 植入物和移植物选择成为影响TMT关节关节结合率的重要可修改因素.

Ankle Joint
3.2K
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...

Structural Joints: Synovial Joints
9.0K
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...

Functional Classification of Joints

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 Joints: Fibrous Joints
4.1K
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...

Knee Joint
3.4K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Structural Joints: Cartilaginous Joints
4.4K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
