まとめ
本症例報告は、小児における稀な両側性ウィンドスウィプト肘変形について詳述する。ドーム骨切り術による内反変形の外科的矯正は、優れた機能的および整容的転帰をもたらした。
科学分野:
- 整形外科学
- 小児整形外科学
- 四肢変形矯正
背景:
- 対側の肘内反および肘外反を特徴とするウィンドスウィプト変形は、上肢では極めて稀である。
- 既存の文献は主に下肢のウィンドスウィプト変形を扱っており、肘の奇形に関する特定のガイドラインは不足している。
研究 の 目的:
- 小児患者における両側性ウィンドスウィプト肘変形の稀な症例を報告する。
- ドーム骨切り術を用いた肘内反の外科的管理の成功例を示す。
- 複雑な四肢変形に対する個別化された治療と計画の重要性を強調する。
主な方法:
- ウィンドスウィプト変形を引き起こす両側性肘外傷を有する8歳男児の症例検討。
- 左肘の肘内反に対するドーム骨切り術とKワイヤー固定による外科的矯正。
- 機能温存のため右肘の肘外反に対する保存的治療。
主要な成果:
- 患者は手術後18ヶ月で、高いMayo Elbow Performance Score(95)および低いDisabilities of Arm, Shoulder, and Hand score(8)により、優れた機能的および整容的結果を達成した。変形または外側顆の突出の再発は認められなかった。対側の外反変形は、機能が温存されていたため許容された。
結論:
- ドーム骨切り術は、ウィンドスウィプト肘変形に対して効果的な多平面矯正を提供し、生体力学および整容を回復させる。
- 対側の解剖学的構造が損なわれている場合、集団ベースの保持角度基準を利用することが外科計画に役立つ。
- 稀な四肢変形における最適な転帰のためには、個別化された外科的決定と患者中心のケアが不可欠である。

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.

Deformation in a Circular Shaft
One of the distinctive characteristics of circular shafts is their ability to maintain their cross-sectional integrity under torsion. In other words, each cross-section continues to exist as a flat, unaltered entity, simply rotating like a solid, rigid slab. To understand the distribution of shearing stress within such a shaft, consider a cylindrical section inside this circular shaft. This section has a length of L and a radius of R, with one end fixed. The radius of the cylindrical section is...
General Case of Eccentric Axial Loading
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical bending,...

Flail Chest-I
Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
