Knee Joint

2.3K
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

2.9K
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...

科学领域:

  • 整形外科手术 整形外科手术
  • 生物材料工程 生物材料工程
  • 临床结果研究研究

背景情况:

  • 关节整形术 (THA) 的并发症,包括脱,随着预期寿命和手术率的增加而增加.
  • 脱位是THA后第一年内修复手术的主要原因.
  • 高风险患者需要专门的植入物来缓解不稳定性.

研究的目的:

  • 评估双流动性杯 (DMC) 在降低高风险THA患者部不稳定性的有效性.
  • 评估与DMC植入相关的并发症率和功能结果,在具有挑战性的患者队列中.
  • 为了比较DMC与标准植入物的性能,以防止脱位.

主要方法:

  • 对163名患者 (168名部) 的回顾性审查,从2014年至2021年接受了THA与DMC.
  • 在患有神经肌肉疾病或腿部部骨折 (FNF) 的患者中进行DMC植入.
  • 使用SPSS对临床结果,不稳定性和并发症的分析,用千平方和t测试进行统计比较.

主要成果:

  • 163名患者的平均随访时间为48个月 (平均年龄为58岁).
  • 没有发生需要修改的脱位;一个没有金属头部脱位的假肢内脱位病例被修改.
  • 四年后,哈里斯关节评分 (HHS) 从手术前的49到术后的89显著改善.

结论:

  • 双流动性杯 (DMC) 有效地降低了高风险THA患者的脱位率,包括那些患有FNF的患者.
  • 植入DMC可以提高患者的满意度,并恢复近乎正常的功能.
  • 对于被确定为脱位高风险的患者,建议对DMC进行更大的考虑.
