Scaphotrapezial trapezoidal (STT) osteoarthritis (OA) is a common degenerative disease of the wrist, specifically at the site of articulation among the scaphoid, trapezium, and trapezoid. Dorsal intercalated segment instability (DISI) may coexist with STT joint OA.

2024年7月31日 · Scaphotrapeziotrapezoidal (STT) or triscaphe joint arthritis is common, occurring on ~9% (range 2-16%) of wrist radiographs 3,4. It is typically degenerative (i.e. osteoarthritis) affecting the triscaphe articulation and presents with radial-sided wrist or base of thumb pain in patients over 50 years 1,2,4.

2021年6月1日 · Scaphotrapeziotrapezoid osteoarthritis (STT OA) is common and often associated with thumb basal joint arthritis. Pain at the base of the thumb on the volar aspect and during resisted extension is characteristic of symptomatic STT OA.

2005年11月1日 · The STT view clearly shows first (A) nonunion and then (B) solid fusion after grafting between the scaphoid, trapezium, and trapezoid. We have described an x-ray view that isolates the articular surfaces of the trapezoid and is aimed directly at the STT, thus showing the whole joint including good visualization of the trapeziotrapezoid and STT ...

2021年7月26日 · Two musculoskeletal radiologists independently assessed visibility, signal intensity (SI), morphology, and thickness of the radiopalmar scapho-trapezial ligament (rpSTL), palmar scapho-capitate capsular ligament (pSCL), palmar STT capsule (pSTTC), and dorsal STT capsule (dSTTC).

2019年5月18日 · The scaphotrapeziotrapezoid joint (STTJ) has a complex osseous and ligamentous anatomy. Precise radiographic assessment is paramount when assessing osteoarthritic, post-traumatic, or post-operative patients. There has been no described technique to image the STTJ without any wrist movement, unobscured by the rest of the carpus.

2016年8月3日 · The triscaphe joint is the shared joint between the scaphoid, trapezium and trapezoid bones in the wrist. This joint is also referred to by its much longer name, the scaphotrapeziotrapezoid (STT) joint.

2011年11月1日 · Scaphotrapeziotrapezoidal arthritis - “ Scaphotrapeziotrapezoidal (STT) or triscaphe joint arthritis is common, occurring on ~9% (range 2-16%) of wrist radiographs 3,4. It is typically d...”

2022年10月15日 · 论文提出了一个聚焦文本的 超分辨率 框架，称为场景文本Telescope(STT)。在文本级布局方面，提出了一个基于Transformer的超分辨网络(TBSRN)，包含一个自注意模块来提取序列信息，对任意方向的文本具有 鲁棒性 。在字符级的细节方面，提出了一个位置感知模块和 ...

Results: Optimal STTJ imaging was in the semi-pronated wrist position with the X-ray beam tilted caudal. We found that the STTJ was best visualized at 48° supination from a fully pronated wrist and a caudal beam angle of 22°.
