概括
先前存在的关节 (SI) 关节自融合与较高前列 (HAC) 骨骨折的发生率有关. 这表明SI关节自融合改变了骨损伤模式.
科学领域:
- 整形外科手术 整形外科手术
- 创伤外科手术是什么
- 放射学 放射学是一门学科.
背景情况:
- 骨骨折模式受到施加力的方向的影响.
- 已经观察到先前存在的关节 (SI) 关节自融合和高前列 (HAC) 关节损伤之间的事关联.
研究的目的:
- 为了研究和比较在患有和没有受伤前SI关节自融合的患者中骨骨折的模式.
主要方法:
- 在2008年至2018年期间,对371名接受单边乙骨固定治疗的成年患者进行了回顾性审查.
- 对损伤放射和CT扫描进行分析,以确定骨折模式和先前存在的SI关节自融合 (aSIJ).
- 骨折类型被分类,特别注意HAC损伤的存在 (前列,前列后半横,或两列骨折).
主要成果:
- 在371名患者中,61名 (16%) 患者有SIJ的证据. 这些患者年龄较大,更有可能是男性,不太可能吸烟,并且由于低能量的机制而受到持续伤害.
- SI关节自融合与HAC损伤的更高可能性显著相关 (OR=4.97,p<0.01).
- 在调整年龄,机制和BMI (OR=2.60,p=0.01) 之后,这种关联仍然显著.
结论:
- 以前存在的SI关节自融合似乎修改了典型的失效模式在acetabular损伤.
- 由于SI关节自融合,较为刚硬的后骨盆环可能会使个体易患HAC骨骨折.

Knee Joint
2.0K
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...

Bones of the Lower Limb: Femur and Patella
2.6K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Ankle Joint
1.6K
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...

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.

Articulations of the Vertebral Column
2.0K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
