Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Knee Joint01:23

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 group...

まとめ
この要約は機械生成です。

ヒップまたは膝の置換手術後の長期のボディマス指数 (BMI) は通常,有意に変化しません. 多くの患者は体重の変動を経験しますが,関節整形手術は総合的なBMI改善のための信頼できる方法ではありません.

科学分野:

  • 整形 術
  • 代謝 健康
  • バイオ統計学

背景:

  • トータルヒップ関節整形手術 (THA) やトータル膝関節整形手術 (TKA) を受けた患者は,しばしば体重減少を目的としています.
  • これらの手順の後のボディ・マス・インデックス (BMI) の長期的な変化は,ほとんど不明です.

研究 の 目的:

  • プライマリーTHAとTKAの2,5,10年後のBMIの変化を分析する.
  • これらの関節置換手術後の BMI変化の予測要因を特定する.

主な方法:

  • 主要関節整形手術を受けた763人の患者 (310 THA,453 TKA) の遡及分析 (2001年 - 2011年).
  • 手術と2, 5, 10年の術後で収集されたBMIデータ
  • 繰り返し測定されたANOVAとBMI変化分析および予測因子の特定に使用された多項論理回帰.

主要な成果:

  • 平均BMIはTHAとTKAの2年と5年後にわずかに増加したが,10年後にベースラインに戻った.
  • 10年後には27~30%の患者でBMIが5%以上低下し,30~32%の患者でBMIが5%以上上昇した.
  • 女性の性別はTHA後にBMIが> 5%増加すると予測され,高齢者はTKA後に減少すると予測された.

結論:

  • ほとんどの患者にとって,関節整形手術は総合的なBMIの有意な改善をもたらしません.
  • 個人のBMIの変化は,手術後10年後に実質的に (> 5%) 変化することがあります.
  • 性別や年齢などの人口統計的要因は 関節置換後の臨床的に重要な体重変化を予測できます
