Sawirka Orthopedic: The "Terry Thomas Sign" iyo Kala-baxa Scapholunate

Terry Thomas waa majaajiliiste caan ah oo u dhashay dalka Ingiriiska oo caan ku ahaa farqiga u dhexeeya ilkihiisa hore.

Dhaawacyada gacanta, waxaa jira nooc dhaawac ah oo muuqaalkiisa shucaaca uu u eg yahay farqiga iliga ee Terry Thomas. Frankel waxa uu tan u tixraacay sida "calaamadaha Terry Thomas," oo sidoo kale loo yaqaan "calaamad faraqa ilka yar."

Muuqaalka Shucaaca: Marka ay jirto kala-baxa scapholunate iyo jeexjeexa xuubka scapholunate interosseous ligament, aragtida anteroposterior ee curcurka ama aragtida wadnaha ee CT waxay muujinaysaa farqiga korodhka ah ee u dhexeeya scaphoid iyo lafaha lunate, oo u eg farqiga ilig yar.

Falanqaynta Saxiixa: Kala-baxa Scapholunate waa nooca ugu badan ee xasillooni-darrada curcurka, oo sidoo kale loo yaqaan 'scaphoid rotary subluxation'. Caadi ahaan waxaa sababa isku darka fidinta, leexashada ulnar, iyo xoogag leexin ah oo lagu dabaqo dhinaca calaacalaha ee curcurka, taasoo keentay dillaaca seedaha dejinaya cirifka u dhow ee scaphoid, taasoo horseedaysa kala soocida lafaha scaphoid iyo lunate. . Xididdada dammaanadda shucaaca iyo ligamentiga radioscaphocapitate sidoo kale waa la jeexjeexay.

Dhaqdhaqaaqyada soo noqnoqda, dhaawacyada xajinta iyo wareega, caajisnimada seedaha ee lagu dhasho, iyo kala duwanaansho xun ee ulnar ayaa sidoo kale lala xiriiriyaa kala-baxa scapholunate.

Baaritaanka Sawirka:X-ray (oo leh isbarbardhig laba geesood ah):

1. Farqiga Scapholunate> 2mm ayaa laga shakisan yahay kala-goynta; haddii> 5mm, waa la ogaan karaa.

2. Calaamadda giraanta scaphoid, oo leh masaafada u dhaxaysa xudduudda hoose ee giraanta iyo dusha wadajirka ah ee isgoysyada oo ah <7mm.

3. Scaphoid gaabin.

4. Kordhinta xagasha scapholunate: Sida caadiga ah, waa 45-60 °; xagasha radiolunate> 20° waxay tusinaysaa xasiloonidarida Qaybta Dhexdhexaadinta ee Dorsal (DISI).

5. Calamada Palmar "V": Muuqaalka caadiga ah ee dhinaca dambe ee curcurka, cidhifyada calaacalaha ee lafaha metacarpal iyo radial waxay sameeyaan qaab "C". Marka uu jiro dabacsanaan aan caadi ahayn ee scaphoid, cidhifkeeda calaacalaha ah ayaa isku xidha cidhifka calaacalaha ee styloid radial, samaynta qaab "V".
