The first type of TFCC tear is due to natural wear, and the other is usually from injury. Tears due to wear are the most common and are usually not seen in younger people. They become more common as one gets older. Tears from injury can come from: A fall on the hand or wrist; A twisting injury (like a drill bit catching, causing a twist of the arm) The triangular fibrocartilage complex (TFCC) is a load-bearing structure between the lunate, triquetrum, and ulnar head. The function of the TFCC is to act as a stabilizer for the ulnar aspect of the wrist. The TFCC is at risk for either acute or chronic degenerative injury. Forced ulnar deviation and positive ulnar variation carry associations with injuries to . Ulna Fovea Test | TFCC. Sharpey’s Test. Sharpey’s Test | TFCC. It should be remembered that the ‘gold standard’ is still considered to be an arthroscopic procedure (Prosser, Harvey, LaStayo, Hargreaves, Scougall, & Herbert, 2011). . TFCC injury mechanisms will often involve repetitive high forces on the wrist, extension and/or ulnar .- when this test is positive (as compared to opposite wrist), then RU intability is present; - this test can be helpful in diagnosing a complete peripheral tear of the TFCC; - sensitivity (0.59), the specificity (0.96), the positive predictive value (0.91), and the negative predictive value;
pronation ballotment test - 라면 volar TFCC tear . MRI 에서 ulnar head의 dorsal subluxation이나 ECU subluxation, fovea 주변 signal change, MRA 에서 조영제가 새는지 등으로 확인 해 볼 수 있지만 tear 가 확실하지 않은 경우도 많기 때문에 이학적검사가 더 .Because the operative and non-operative approaches to TFCC pathology vary widely depending upon the tear type and location, such information is invaluable for the proper management of patients with TFCC tears. References. 1 Palmer AK, Werner FW: The triangular fibrocartilage complex of the wrist–anatomy and function. J Hand Surg [Am] 1981 Mar . Arthroscopic repair is performed for fovea injuries of the triangular fibrocartilage complex (TFCC) when instability of the distal radioulnar joint results in pain, decreased grip strength, and mechanical symptoms. During TFCC repair, reconstruction of its attachment to the fovea is important. Nonabsorbent suture tapes have gained attention for ligament repair in the .
TFCC tears with foveal disruption and instability of the distal radioulnar joint (DRUJ) require direct repair of the TFCC to the ulnar fovea. The traditional method of foveal TFCC repair involves an open surgical approach through the floor of the 5th dorsal compartment. . The hook test is more accurate than the trampoline test to detect .
The TFCC (light blue) is best palpated in the soft spot between the ulnar styloid, FCU and volar surface of the ulnar head. This is known as the ulna fovea sign (Ko et al., 2012; Sachar, 2008; Tay et al., 2007). The fovea sign test has a 95.2% sensitivity and 86.5% specificity (Sachar, 2008, p.1671; Tay et al., 2007, P483). That is, it is . The TFCC acts as a primary stabilizer to the distal radioulnar joint (DRUJ) and a cushion to the ulnar-sided carpal bones, transmitting up to 18% of the load on the wrist (2). fovea test . used to evaluate for TFCC tear or ulnotriquetral ligament tear. performed by palpation of the ulnar wrist between the styloid and FCU tendon.

Figure from Internet 三角纖維軟骨複合體，英文又名 Triangular fibrocartilage complex TFCC 是手腕尺側疼痛常見的原因之一。在反覆使用手腕的工作或運動項目上可能發生，但臨床上更常見的情境是在跌倒撐地之後產生症狀。TFCC 的損傷不太好處理，常常需要一段時間的治療，剛好最近 Dr. M 自己因為幫病人打針 .During the last two decades, increased knowledge of functional anatomy and pathophysiology of the triangular fibrocartilage complex (TFCC) have contributed to a change in surgeons' perspective toward it. The earlier concept of the TFCC as the "hammock" structure of the ulnar carpus has updated to th .
The TFCC functions to transmit axial load and to stabilize both the distal radioulnar joint (DRUJ) and the ulnocarpal joint. Approximately 20% of the distal radiocarpal load is transmitted through the TFCC and distal ulna when in neutral but this increases with ulnar deviation, pronation, and in those with ulnar positive bony anatomy [1, 5,6,7].A 2.5 mm .The “ulnar fovea sign” has been suggested as a key finding in patients with ulnotriquetral ligament injuries and foveal tears. 17 The TFCC compression test is a provocative test consisting of axial loading of the ulnocarpal joint with ulnar deviation and rotation. 15, 18 Assessment for asymmetric clicking or clunking associated with pain is .
The triangular fibrocartilage complex (TFCC) plays an important role at the distal radioulnar joint (DRUJ) by providing stability and serving as a shock absorber and load transmitter. 1–4 Given the functional role of the ulnar wrist and its use in many activities of daily living and athletics, injuries of the TFCC are common. 5–7 Injuries may occur in isolation or in combination with other .
Palmer’s classification of TFCC injury 4 has undoubtedly contributed to establishing the concept of TFCC injury and its treatment; however, while type 1B injuries in this classification are defined as peripheral tears located on the ulnar side of the TFCC, it does not clearly reference the foveal tear. Thus, the foveal tear is relatively new concept.
The fovea is a groove that separates the ulnar styloid from the ulnar head. The groove is at the junction of the ulnar bone and wrist. The styloid is a small bump on the edge of the wrist (on the side away from the thumb) where the ulna meets the wrist joint. Later we will talk about the fovea test to diagnose TFCC injuries.

When positive, it is a reliable test to diagnose tear of the ulno-triquetral ligament tear or disruption of the foveal attachment of the TFCC. This test has high sensitivity of 95.2% and a specificity of 86.5%. The TFCC compression test is performed by ulnar deviating the forearm in neutral rotation.

On a systematic examination of the painful wrist, the differential diagnosis and/or confirmation of the diagnosis of a peripheral TFCC tear is achieved by means of special provocative maneuvers and diagnostic tests. 3,11 The most reliable clinical sign of a peripheral TFCC tear is the ulnar fovea sign, 12 whereby the patient has point .
