Halbeegyada sawir-qaadista ee aadka loo isticmaalo ee lagu qiimaynayo jabka radius fog sida caadiga ah waxaa ka mid ah xagasha u janjeerta volar(VTA), kala duwanaanshaha ulnar, iyo dhererka shucaaca. Maaddaama fahamkayaga ku saabsan anatomy ee radius fog uu sii qoto dheer yahay, cabbirro sawireed dheeri ah sida fogaanta anteroposterior (APD), xagasha ilmada (TDA), iyo masaafada u dhexeysa dhidibka-radius (CARD) ayaa la soo jeediyay oo lagu dabaqay dhaq-dhaqaaq caafimaad.
Halbeegyada sawirada sida caadiga ah loo isticmaalo si loo qiimeeyo jabka radius fog waxaa ka mid ah: a:VTA：b：APD;c：TDA：d：CARD
Inta badan cabirrada sawiradu waxay ku habboon yihiin jabka xididdada fog ee ka baxsan articular, sida dhererka shucaaca iyo kala duwanaanshaha ulnar. Si kastaba ha noqotee, qaar ka mid ah jabka gudaha articular, sida jabka Barton, cabbirada sawirada dhaqameed ayaa laga yaabaa inay ka maqan yihiin awooddooda inay si sax ah u go'aamiyaan calaamadaha qalliinka oo ay bixiyaan hagitaan. Waxaa guud ahaan la rumeysan yahay in calaamadda qalliinka ee qaar ka mid ah jabka gudaha ee gudaha ay si dhow ula xiriirto ka-baxsanaanta dusha wadajirka ah. Si loo qiimeeyo heerka barokaca ee jabka gudaha articular, aqoonyahanno ajnabi ah ayaa soo jeediyay cabbir cusub oo cabbir ah: TAD (Tilt After Displacement), waxaana markii ugu horreysay la soo sheegay in lagu qiimeeyo jabka malleolus ee dambe oo ay weheliso barokaca tibial fog.
Dhamaadka fog ee tibia, xaaladaha jabka dambe ee malleolus oo leh kala-bax xagga dambe ee talus, dusha wadajirka ah wuxuu sameeyaa saddex geesood: Arc 1 waa dusha hore ee wadajirka ee tibia fog, Arc 2 waa dusha wadajirka ah ee malleolus dambe. jajab, iyo Arc 3 waa meesha ugu sarreysa talus. Marka uu jiro jajab jabka malleolus ee dambe oo ay weheliso kala-baxa dambe ee taluska, bartamaha goobada uu sameeyay Arc 1 ee dusha hore ee wadajirka ah waxaa lagu tilmaamaa dhibic T, iyo bartamaha goobada uu sameeyay Arc 3 ee sare Talus waxaa lagu tilmaamaa dhibic A. Masaafada u dhaxaysa labadan xarumood waa TAD (Janjabinta Barakaca ka dib), iyo barokaca weyn, waa badan yahay qiimaha TAD.
Ujeedada qaliinka waa in la gaaro ATD (Janjabinta Barakaca Kadib) qiimaha 0, taas oo muujinaysa hoos u dhaca anatomical ee dusha wadajirka ah.
Sidoo kale, xaalada jabka Barton ee volar:
Qaybaha la barokiciyay oogada sare ee articular waxay sameeyaan Arc 1.
Wajiga lunate wuxuu u adeegaa sida Arc 2.
Dhinaca dhabarka ee raadiyaha (lafo caadi ah oo aan jabnayn) waxay u taagan tahay Arc 3.
Mid kasta oo ka mid ah saddexdan geesood waxaa loo tixgalin karaa sidii goobo. Mar haddii wejiga lunate iyo jajabka lafaha isug jira la wada barokiciyo, Goobabada 1 (oo jaale ah) waxay la wadaagtaa xarunteeda goobabada 2 (cadaan). ACD waxay matalaysaa fogaanta u jirta xaruntan la wadaago ilaa bartamaha Circle 3. Ujeedada qaliinka waa in ACD dib loogu soo celiyo 0, taasoo muujinaysa hoos u dhaca anatomical.
Dhaqankii hore ee kiliinikada, waxaa si weyn loo aqbaley in tallaabada dusha sare ee wadajirka ah ee <2mm ay tahay heerka dhimista. Si kastaba ha ahaatee, daraasaddan, falanqaynta qalooca ee Receiver Operating Characteristic (ROC) ee qiyaasaha sawir-qaadista ee kala duwan ayaa muujisay in ACD ay leedahay meesha ugu sareysa ee hoos timaada qalooca (AUC). Isticmaalka qiimaha goynta ee 1.02mm ee ACD, waxay muujisay 100% dareenka iyo 80.95% gaar ahaaneed. Tani waxay soo jeedinaysaa in habka dhimista jabka, yaraynta ACD ee gudaha 1.02mm ay noqon karto shuruud macquul ah.
marka loo eego heerka soo jireenka ah ee <2mm korka wadajirka ah ee tallaabo-off.
ACD waxay u muuqataa inay leedahay tixraac qiimo leh oo lagu qiimeeyo heerka barokaca ee jabka gudaha articular ee ku lug leh kala-goysyada diirada saaraya. Marka lagu daro codsigeeda qiimeynta jabka tibial plafond iyo jabka radius fog sida horay loo sheegay, ACD sidoo kale waxaa loo shaqaaleysiin karaa qiimeynta jabka suxulka. Tani waxay siinaysaa dhakhaatiirta kiliinikada qalab waxtar leh oo lagu dooranayo hababka daaweynta iyo qiimeynta natiijooyinka dhimista jabka.
