I-Imaging Orthopedic: I-"Terry Thomas Sign" kanye ne-Scapholunate Dissociation

UTerry Thomas ungusomahlaya odumile waseBrithani owaziwa ngegebe lakhe elimangalisayo phakathi kwamazinyo akhe angaphambili.

Ekulimaleni esihlakaleni, kunohlobo lokulimala okubukeka kwayo ngeradiographic kufana negebe lamazinyo likaTerry Thomas. UFrankel ubize lokhu ngokuthi "uphawu lukaTerry Thomas," owaziwa nangokuthi "uphawu lwegebe lezinyo elincane."

Ukubukeka Kwe-Radiographic: Uma kukhona ukuhlukaniswa kwe-scapholunate nokudabuka kwe-scapholunate interosseous ligament, umbono we-anteroposterior wesandla noma umbono we-coronal ku-CT ubonisa igebe elikhulayo phakathi kwamathambo e-scaphoid kanye nenyanga, efana negebe lezinyo elincane.

Ukuhlaziywa Kwezimpawu:I-scapholunate dissociation uhlobo oluvame kakhulu lokungaqini kwezihlakala, okubuye kwaziwe ngokuthi i-scaphoid rotary subluxation. Ngokuvamile kubangelwa inhlanganisela yokwandiswa, ukuchezuka kwe-ulnar, kanye namandla okugoba asetshenziswa ohlangothini lwesandla sesandla se-ulnar, okuholela ekuqhekekeni kwemigqa eqinisa i-proximal pole ye-scaphoid, okuholela ekuhlukaneni phakathi kwe-scaphoid ne-lunate bone. . Umsipha we-radial collateral ligament kanye ne-radioscaphocapitate ligament kungase futhi kudabuke.

Imisebenzi ephindaphindiwe, ukulimala okubambekayo nokujikelezayo, i-congenital ligament laxity, kanye nokuhlukahluka okungalungile kwe-ulnar nakho kuhlotshaniswa nokuhlukaniswa kwe-scapholunate.

Ukuhlolwa Kwesithombe:I-X-ray (ngokuqhathanisa kwamazwe amabili):

1. Igebe le-scapholunate > 2mm liyasolisa ngokuzihlukanisa; uma > 5mm, kungatholakala.

2. Uphawu lweringi ye-scaphoid cortical, nebanga phakathi komngcele ongezansi weringi kanye nendawo ehlangene ehlangene ye-scaphoid ingu-<7mm.

3. Ukunciphisa i-scaphoid.

4. Ukwenyuka kwe-angle ye-scapholunate: Ngokuvamile, i-45-60 °; i-engeli ye-radiolunate > 20° ikhombisa Ukungaqini Kwesigaba Se-Dorsal Intercalated Segment (DISI).

5. Uphawu lwe-Palmar "V": Ekubukeni okuvamile kwesandla sesihlakala, imiphetho yesundu ye-metacarpal kanye namathambo e-radial akha umumo othi "C". Uma kukhona ukugoba okungavamile kwe-scaphoid, unqenqema lwentende yesandla lunqamula unqenqema lwentende yesitayela se-radial, kwakheka umumo othi "V".
