Ubuchwephesha boTyando | "I-Kirschner Wire Tension Band Technique" yoLungiso lwaNgaphakathi kuNyango lwe-Bennett's Fracture.

Ukwaphuka kwe-Bennett kubangela i-1.4% yokuphuka kwezandla. Ngokungafaniyo nokwaphuka okuqhelekileyo kwesiseko samathambo e-metacarpal, ukufuduswa kwe-Bennett fracture yahlukile. Iqhekeza le-articular surface fragment ligcinwe kwindawo yalo yokuqala ye-anatomical ngenxa yokutsalwa kwe-oblique metacarpal ligament, ngelixa i-distal fragment, ngenxa ye-traction ye-abductor pollicis longus kunye ne-adductor pollicis tendons, ikhupha i-dorsoradially kunye ne-supinates.

Ulwaphulo lwe-Bennett olufudukayo, unyango lotyando ludla ngokucetyiswa ukuphepha ukuphazamisa ukulungelelaniswa kwe-carpometacarpal joint and thumb function. Ngokweendlela zonyango zonyango, i-plate kunye ne-screw fixation systems, kunye ne-Kirschner wire fixation yangaphakathi, isetyenziswa ngokubanzi kwiikliniki. Izifundiswa ezisuka kwiSibhedlele seSithathu saseHebei zenze isindululo sobuchule bebhendi yocingo yaseKirschner, ebandakanya ulwakhiwo oluncinci lokusikeka ukulungisa iifracture zikaBennett, ukuzuza iziphumo ezilungileyo.

Inyathelo loku-1: Yenza i-1.3 cm yokusika kwicala le-radial ye-carpometacarpal joint, u-dissect layer by layer ukuze uveze indawo, ubuyise i-abductor pollicis longus kwicala le-ulnar, kwaye uveze i-dorsal ye-carpometacarpal joint.

Inyathelo lesi-2: Faka i-traction manual kwaye uchaze ubhontsi ukunciphisa ukwaphuka. Faka i-1 mm ye-Kirschner ucingo kwi-distal fracture end, i-1-1.5 cm kude ne-carpometacarpal joint, ukulungisa iqhekeza lethambo elisondeleyo. Emva kokuba ucingo lweKirschner lungene kwiqhekeza lethambo, qhubeka uqhubela phambili nge-1 cm.

Inyathelo lesi-3: Thatha ucingo kwaye uyiluke kwipatheni yomzobo wesibhozo ujikeleze iziphelo zombini zocingo lwaseKirschner, emva koko ukhuseleke endaweni.

Ubuchule bebhendi yentsimbi yeKirschner busetyenziswe kuninzi lwezahlulo, kodwa kukwaphuka kukaBennett, ukusika okuncinci kuhlala kukhokelela ekungabonakali kakuhle kwaye kwenza inkqubo ibenzima. Ukongezelela, ukuba i-fracture iyancitshiswa, ucingo olulodwa lwe-Kirschner alukwazi ukuzinzisa ngokufanelekileyo iqhekeza lethambo elisondeleyo. Ukusebenza kwayo kweklinikhi kunokunqongophala. Ngaphandle kwale ndlela ikhankanywe ngasentla yokulungisa ibhendi yoxinzelelo, kukwakho neKirschner wire fixation edityaniswe nobuchule bebhendi yoxinzelelo, ekwaxelwe kuncwadi.
