まとめ
ネクセル全肘関節整形術 (TEA) は,4年間の研究で,緩解による5%の修正率を示しました. 再手術と合併症は一般的であったが,ほとんどの患者は痛みの軽減と運動範囲の改善を経験した.
科学分野:
- 整形外科 整形外科
- バイオメディカルエンジニアリング
- 関節整形術の研究 アートロプラスティの研究
背景:
- ネクセル全肘関節整形術 (TEA) は,クオンラード・モリー TEA 設計の改善のために開発されました.
- ネクセルTEAの改訂率が高いこと,特に緩和による改訂率の高さについて懸念があります.
研究 の 目的:
- ネクセル全肘関節整形手術の臨床結果と改修率を評価する.
- インプラント生存率とNexel TEAに関連した合併症を評価する.
主な方法:
- 2015年から2021年までの101のネクセル・プライマリ・TEAの遡及的レビュー.
- ノルウェーの関節整形術登録簿,電子医療記録,放射線診断から得られたデータです.
- インプラントの改修,二次手術,合併症,X線解離,メイヨー・エルボウ・パフォーマンス・スコア (MEPS),運動範囲 (ROM),痛み (NRS) の評価.
主要な成果:
- 平均44ヶ月のフォローアップ期間中に,インプラントの修正が5回 (5%) 発生し,そのうち2回は無菌的な緩解に起因しました.
- アセプティックな緩解が疑われる追加の4つの症例は,放射線検査で特定されました.
- 38件の二次手術と27件の合併症が,それぞれ18本の肘と22本の肘で記録されました.
- 患者の81%が良好または優れた臨床結果 (MEPS) を達成した.
- 平均ROM (87°から113°) と痛みのスコア (休息:4.0から0.8;活動:7.9から1.7) の有意な改善が観察されました.
結論:
- Nexel TEAは,このコホートにおける無菌的な緩解による5%の修正率を示した.
- 再手術と合併症の発生率は頻繁でしたが,TEAの予想範囲に匹敵していました.
- この処置により,急性骨折の症例では,骨折後の症例と比較して,よりよい結果が得られ,顕著な臨床的改善がもたらされました.

Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal 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 group...

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...
Development of the Limb Synovial Joints
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
