The ulna grinding test is conducted with the patient’s forearm fixed and the wrist held in dorsiflexion. Then, an axial load is applied, while the wrist is rotated and deviated in ulnar direction. This test is positive in the case that pain and crepitations are reproduced.

2024年5月3日 · What is the Ulnar Compression Grind Test? The Ulnar Compression Grind Test diagnoses TFCC tears or injuries in the wrist. This test focuses on the TFCC, which supports carpal bones and stabilises the wrist’s ulnar side. The TFCC is vital for wrist movement and load distribution, especially during gripping.

If the distal ulna is prominent on the affected side, this suggests distal radioulnar joint instability which can have associations with TFCC injury. If the palms are relaxed and the ulnar head goes back to normal position, this is a positive test; Grind test: Compress the radius and ulna and have the patient rotate the forearm.

2021年5月23日 · examiner stabilizes distal radius and ulna with non-dominant hand and moves patients wrist from radial deviation to ulnar deviation, whilst applying an axial load a positive test occurs when a clunk is felt when the wrist is ulnarly deviated

Reagan’s Test, Sometimes called the lunotriquetral ballottement test. The examiner pronates the affected hand and stabilize the lunate. They then push up on the triquetrum and down on the lunate. Examiner should observe for tenderness or pain and compare to the contralateral hand. A positive test includes pain, subluxation or crepitus.

2017年7月3日 · The ulnar grind test is a provocative test that encompasses dorsiflexion of the wrist, axial load, and ulnar deviation or rotation. Imaging can include posterior/anterior x-ray to check ulnar variance, tri-compartment arthrogram, or MRI/MRA.

2023年4月13日 · TFCC 是位在手腕處尺骨側的結構，位在 Lunate, Triquetrum, Ulnar 與 Radial head 之間，主要負責遠端橈尺關節 Distal radioulnar joint DRUJ 的穩定度，並且扮演著吸震的功能。 在正常的 Ulnar variance 下大約負擔 20% 的軸向負荷。 TFCC 主要由以下幾個結構所組成：

2023年8月14日 · If the palms are relaxed and the ulnar head goes back to normal position, this is a positive test. Grind test: Compress the radius and ulna and have the patient rotate the forearm. Pain could indicate a degenerative process.

- patients will TFCC tears, often show pain w/ forced forearm pronation and supination or pain with gripping and ulnar deviation; - pts w/ TFCC tears that are symptomatic often note a painful click during wrist motions;

2023年6月17日 · Eliciting tenderness in the region of ulnar fovea is a commonly done test for TFCC injury (Rosemary [6]). The ulnar fovea, the so-called the ulnar snuffbox, is a soft spot located between the ulnar styloid and the pisiform bone.
