Terry Thomas munyarikani weBritish ane mukurumbira anozivikanwa nemukaha wake wechiratidzo pakati pemeno ake epamberi.
Mukukuvadzwa kwemaoko, kune rudzi rwekukuvara uko kutaridzika kweradiographic kwakafanana negeji rezino raTerry Thomas. Frankel akataura izvi se "Terry Thomas chiratidzo," inozivikanwawo se "sparse zino gap sign."
Radiographic Kuonekwa: Kana paine scapholunate dissociation uye kubvaruka kweiyo scapholunate interosseous ligament, iyo anteroposterior maonero echanza kana coronal maonero paCT inoratidza yakawedzera gaka pakati pe scaphoid uye mapfupa emwedzi, yakafanana negeno rezino.
Sign Analysis:Scapholunate dissociation ndiyo yakajairika mhando yekusagadzikana kwemaoko, inozivikanwawo se scaphoid rotary subluxation. Zvinowanzokonzerwa nekubatanidzwa kwekuwedzera, kutsauka kwechiuno, uye simba rekusimudzira rinoshandiswa kune ulnar palmar side ye wrist, zvichiita kuti kuputika kwemarunda kugadzikane proximal pole ye scaphoid, zvichiita kuti kuparadzaniswa pakati pe scaphoid uye mapfupa emwedzi. . Iyo radial collateral ligament uye radioscaphocapitate ligament inogonawo kubvaruka.
Zviitiko zvinodzokorora, kubata uye kukuvara kwekutenderera, congenital ligament laxity, uye negative ulnar variance zvinosanganiswawo ne scapholunate dissociation.
Kufungidzira Kuongorora: X-ray (ine kuenzanisa kwemaviri):
1. Scapholunate gap> 2mm inonyumwira pakuparadzana; kana> 5mm, inogona kuongororwa.
2. Scaphoid cortical ring sign, ine chinhambwe pakati pemuganhu wezasi wemhete uye pedyo nepamusoro pejoint surface ye scaphoid iri <7mm.
3. Scaphoid shortening.
4. Kuwedzera scapholunate angle: Kazhinji, ndeye 45-60 °; radiolunate angle > 20 ° inoratidza Dorsal Intercalated Segment Instability (DISI).
5. Chiratidzo chePalmar "V": Pamusoro pemaonero akajairika echanza, mipendero yemichindwe ye metacarpal uye radial bones inoumba "C" chimiro. Kana paine kuchinjika kusingaite kwe scaphoid, mupendero wayo wepalmar unopindirana nemupendero wepalmar weradial styloid, kuumba "V" chimiro.
