Indlela Yotyando | “Indlela Yokusebenzisa Ibhendi Yoxinzelelo Lwentambo KaKirschner” Yokulungisa Ingaphakathi Kunyango Lokwaphuka Kwethambo LikaBennett

Ukuqhekeka kukaBennett kubangela i-1.4% yokuqhekeka kwesandla. Ngokungafaniyo nokuqhekeka okuqhelekileyo kwesiseko samathambo e-metacarpal, ukufuduka kokuqhekeka kukaBennett kwahlukile. Iqhekeza lomphezulu we-articular elikufutshane ligcinwa kwindawo yalo yokuqala yomzimba ngenxa yokutsalwa kwe-ligament ye-oblique metacarpal, ngelixa iqhekeza elikude, ngenxa yokutsalwa kwe-abductor pollicis longus kunye ne-adductor pollicis tendons, liqhekeka ngasemva kwaye libheke phezulu.

Kwizaphuko zikaBennett ezisusiweyo, unyango lotyando ludla ngokucetyiswa ukuze kuthintelwe ukulungelelaniswa komsebenzi wejoyinti ye-carpometacarpal kunye nobhontsi. Ngokuphathelele iindlela zonyango lotyando, iinkqubo zokulungisa iipleyiti kunye nezikrufu, kunye nokulungiswa kwangaphakathi kwentambo kaKirschner, zisetyenziswa kakhulu kwimisebenzi yezonyango. Iingcali ezivela kwiSibhedlele sesiThathu saseHebei zicebise indlela yokusebenzisa ibhendi yoxinzelelo lwentambo kaKirschner, equka ukunqunyulwa okuncinci okungafunekiyo ukulungisa izaphuko zikaBennett, okufezekisa iziphumo ezilungileyo.

Inyathelo 1: Yenza ukusika okungange-1.3 cm kwicala le-radial le-carpometacarpal joint, ukwahlulahlula umaleko ngomnye nomnye ukuze uveze indawo, ubuyisele i-abductor pollicis longus kwicala le-ulnar, kwaye uveze icala le-dorsal le-carpometacarpal joint.

Inyathelo lesi-2: Sebenzisa intambo ngesandla uze uphakamise ubhontsi ukuze unciphise ukwaphuka. Faka ucingo lweKirschner oluyi-1 mm kwisiphelo sokuqhekeka okukude, ukusuka kwi-1-1.5 cm ukusuka kwijoyinti ye-carpometacarpal, ukuze ulungise iqhekeza lethambo elikufutshane. Emva kokuba ucingo lweKirschner lungene kwiqhekeza lethambo, qhubeka uluqhubela phambili nge-1 cm.

Inyathelo lesi-3: Thatha ucingo uze ulujikelezise ngendlela efana nepatheni yesibhozo ujikeleze omabini amacala ocingo lweKirschner, uze uluqinise endaweni yalo.

Indlela yeKirschner wire tension band isetyenzisiwe kwiindawo ezininzi ezaphukileyo, kodwa kwiingozi zikaBennett, ukunqunyulwa okuncinci kudla ngokubangela ukuba kungabonakali kakuhle kwaye kwenza inkqubo ibe nzima. Ukongeza, ukuba ukwaphuka kunqunyulwe, intambo enye kaKirschner isenokungazinzisi ngokufanelekileyo iqhekeza lethambo elikufutshane. Ukusebenza kwayo kwezonyango kunokulinganiselwa. Ngaphandle kwendlela yokulungisa i-tension band ekhankanyiweyo apha ngasentla, kukwakho nokulungisa i-Kirschner wire fixation edityaniswe nendlela ye-tension band, ekwaxelwa ngayo kwiincwadi.
