背景:
- 重度のハルクス・ヴァルガス (HV) は手術上の課題であり,従来の方法は侵襲的であり,新しい最小侵襲的技術は合併症を伴う.
- この研究は,通常は軽度の症例に使用される技術である,重度のHV変形に対する皮膚経端骨髄切除の有効性を調査しています.
研究 の 目的:
- 重度のハルクス・ヴァルガス (HV) 変形を矯正する経皮遠足骨切除の臨床的および放射線学的有効性を評価する.
- 患者の満足度,合併症率,重度のHV症例での再手術率を評価する.
主な方法:
- 重度のハルクス・ヴァルガス (HVA > 40度) の116フィートで,皮膚経由の遠足横断骨切除と横向軟組織解放で治療した後の分析.
- 術前および術後の放射線測定 (HVA,IMAなど) 平均フォローアップ期間は27. 1ヶ月でした.
主要な成果:
- ハルクス・ヴァルガス・アングル (HVA) とインターメタタルス・アングル (IMA) の有意な改善が観察され,AOFASスコアの中央値は44. 0から90. 5に増加した.
- 患者の87. 9%が満足度または非常に高い満足度を示し,重大な合併症は記録されなかった.
- 14. 7%の再手術率 (主に外出症) と6%の再発率が認められ,再手術,外出症,MTPI適合性,および臨床結果との関連が認められた.
結論:
- 経皮遠足骨切除術は重度のアルクス・ヴァルグスの治療に 相当な改善をもたらし,大きな合併症なしに 患者の満足度が高い.

Bone Structure
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone Remodeling and Repair
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
