概括

在全脚关节整形术 (TAA) 中恢复关节线是具有严重骨损失的挑战. 虽然一些放射性参数显示出良好的可重现性,但它们在TAA修复手术中并不完全可靠.

科学领域:

整形外科手术整形外科手术
放射学放射学是一门学科.
生物机械工程生物机械工程

背景情况:

整体脚关节整形术 (TAA) 是常见的创伤后关节炎.
严重的创伤后骨损失 (PTBL) 或TAA修订可以掩盖关节线 (JL) 里程碑.
精确的JL恢复对于TAA成功至关重要.

研究的目的:

评估放射性参数的可复制性,以评估关节线 (JL) 在严重创伤后骨损失 (PTBL) 的全脚关节整形术 (TAA) 中.
根据定制的TAA,将手术和逆侧脚之间的JL参数进行比较.
在复杂的TAA病例中确定可靠的JL恢复方法.

主要方法:

定制的TAA植入物是使用3DCT扫描设计的,用于患有严重PTBL或TAA修订的患者.
放射性参数 (JL高度比,LM-JL,MM-JL,CS-JL距离) 用承重型放射仪进行测量.
评估了观察者内部和观察者间的可靠性和可变性,比较了手术和逆侧肢.

主要成果:

对于评估的参数,观察者内部和观察者间的可靠性是很好的.
侧骨到关节线 (LM-JL) 距离显示出最少的变化.
虽然TAA参数与对侧脚没有显著差异,但发现了关节线近似化的趋势.

结论:

该研究表明,JL评估的评估参数在TAA中具有严重的PTBL时具有良好的可重复性.
然而,由于潜在的弱点,这些参数可能不完全可靠.
需要进一步的研究,以确定在复杂的TAA案例中准确的JL评估的更可重现的比率.

Ankle Joint

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...

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

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...

Knee Joint

Knee Joint

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: Tibia and Fibula

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
