“…1,2 Degenerative TFC lesions are quite common and often occur with chronic ulnar-sided wrist pain without distal radioulnar joint instability. 3, 4 Palmer classified both traumatic (type 1) and degenerative (type 2) TFC lesions and subdivided degenerative lesions into 5 groups (2Ae2E).…”

“…Die klinische Untersuchung zur Diagnose von DRUG-Instabilitäten wird von den meisten Autoren als wichtigste und grundlegende Methode gesehen [23]. Der Vorteil ist die zügige Diagnostik und Unabhängigkeit von Geräten, sowie ein möglicher Seitenvergleich und die durchführbare statische und dynamische Prü-fung.…”

“…Although static joint stability is constituted by osseous and ligamentous integrity, the dynamic elements of joint stability concern proprioceptive control of the compressive and directional muscular forces acting on the joint [3,21]. The core of the distal radioulnar joint stability is best described with the concept of ''tensegrity,'' which entails stability through a synergy of ligament tensile and joint compressive forces [11]. This enables a harmonic rotation of the forearm.…”

Background The triangular fibrocartilage complex is the main stabilizer of the distal radioulnar joint. While static joint stability is constituted by osseous and ligamentous integrity, the dynamic aspects of joint stability chiefly concern proprioceptive control of the compressive and directional muscular forces acting on the joint. Therefore, an investigation of the pattern and types of sensory nerve endings gives more insight in dynamic distal radioulnar joint stability.Questions/purposes We aimed to (1) analyze the general distribution of sensory nerve endings and blood vessels; (2) examine interstructural distribution of sensory nerve endings and blood vessels; (3) compare the number and types of mechanoreceptors in each part; and (4) analyze intrastructural distribution of nerve endings at different tissue depth. Methods The subsheath of the extensor carpi ulnaris tendon sheath, the ulnocarpal meniscoid, the articular disc, the dorsal and volar radioulnar ligaments, and the ulnolunate and ulnotriquetral ligaments were dissected from 11 human cadaver wrists. Sensory nerve endings were counted in five levels per specimen as total cell amount/ cm 2 after staining with low-affinity neurotrophin receptor p75, protein gene product 9.5, and S-100 protein and thereafter classified according to Freeman and Wyke. Results All types of sensory corpuscles were found in the various structures of the triangular fibrocartilage complex with the exception of the ulnolunate ligament, which contained only Golgi-like endings, free nerve endings, and unclassifiable corpuscles. The articular disc had only free nerve endings. Furthermore, free nerve endings were the predominant sensory nerve ending (median, 72.6/cm 2 ; range, 0-469.4/cm 2 ) and more prevalent than all other types of mechanoreceptors: Ruffini (median, 0; range, 0-5.6/cm 2 ; difference of medians, 72.6; p \ 0.001), Pacini (median, 0; range, 0-3.8/cm 2 ; difference of medians, 72.6; p \ 0.001), Golgi-like (median, 0; range, 0-2.1/cm 2 ; difference of medians, 72.6; p \ 0.001), and unclassifiable corpuscles (median, 0; range, 0-2.5/cm 2 ; difference of medians, 72.6; p \ 0.001). The articular disc contained fewer free nerve endings (median, 1.8; range, 0-17.8/cm 2 ) and fewer blood vessels (median, 29.8; range, 0-112.2/ cm 2 ; difference of medians: 255.9) than all other structures of the triangular fibrocartilage complex (p B 0.001, respectively) except the ulnolunate ligament. More blood vessels were seen in the volar radioulnar ligament (median, 363.62; range, 117.8-871.8/cm 2 ) compared with the ulnolunate ligament (median, 107.7; range, 15.9-410.3/cm 2 ; difference of medians: 255.91; p = 0.002) and the dorsal radioulnar ligament (median, 116.2; range, 53.9-185.1/ cm 2 ; difference of medians: 247.47; p = 0.001). Free nerve endings were obtained in each structure more often than all other types of sensory nerve endings (p \ 0.001, respectively). The intrastructural analysis revealed no differences in mechanoreceptor distribution in all investigat...
