Njira Yopangira Opaleshoni | "Kirschner Wire Tension Band Technique" ya Kukonzekera Kwamkati Pochiza Kuphulika kwa Bennett

Kuthyoka kwa Bennett kumapangitsa 1.4% ya kusweka kwa manja. Mosiyana ndi fractures wamba pamunsi pa mafupa a metacarpal, kusamuka kwa fracture ya Bennett ndikwapadera kwambiri. Chidutswa chapamwamba cha articular chimasungidwa pamalo ake oyambirira a anatomical chifukwa cha kukoka kwa oblique metacarpal ligament, pamene chigawo cha distal, chifukwa cha kukoka kwa abductor pollicis longus ndi adductor pollicis tendons, kumatulutsa dorsoradially ndi supinates.

Chifukwa cha fractures ya Bennett yothawa kwawo, chithandizo cha opaleshoni nthawi zambiri chimalimbikitsidwa kuti tipewe kusokoneza mgwirizano wa carpometacarpal joint ndi thumb. Pankhani ya njira zochizira opaleshoni, makina opangira mbale ndi zomangira, komanso Kirschner wire fixation mkati, amagwiritsidwa ntchito kwambiri pazachipatala. Akatswiri a Chipatala Chachitatu cha Hebei apereka njira yolumikizira mawaya a Kirschner, yomwe imaphatikizapo kudula pang'ono pang'ono kuti akonze zosweka za Bennett, kuti zitheke.

Khwerero 1: Pangani 1.3 masentimita odulidwa kumbali yozungulira ya cholumikizira cha carpometacarpal, gawaniza wosanjikiza ndi wosanjikiza kuti muwonetse malowo, chotsani abductor pollicis longus ku mbali ya ulnar, ndikuwonetsa mbali yakumbuyo ya cholumikizira cha carpometacarpal.

Khwerero 2: Ikani kukoka pamanja ndikutchula chala chachikulu kuti muchepetse kuthyoka. Ikani waya wa Kirschner wa 1 mm kupyola kumapeto kwa fracture ya distal, 1-1.5 cm kutali ndi cholumikizira cha carpometacarpal, kukonza kachidutswa kakang'ono ka fupa. Waya wa Kirschner ukalowa m'chidutswa cha fupa, pitilizani kupititsa patsogolo ndi 1 cm.

Khwerero 3: Tengani waya ndikuyiyika mu chifaniziro chachisanu ndi chitatu kuzungulira malekezero onse a waya wa Kirschner, kenaka muteteze m'malo mwake.

Njira ya Kirschner tension band yakhala ikugwiritsidwa ntchito m'mafupa ambiri, koma kwa Bennett fractures, kang'ono kakang'ono kamene kamapangitsa kuti asawoneke bwino ndipo amachititsa kuti njirayi ikhale yovuta. Kuonjezera apo, ngati kupasukako kuchitidwa, waya umodzi wa Kirschner sungathe kukhazikika bwino gawo la fupa la proximal. Kuchita kwake kuchipatala kungakhale kochepa. Kupatula njira yomwe tatchulayi yokonza band, palinso waya wa Kirschner wophatikizidwa ndi njira yolumikizirana, yomwe idanenedwanso m'mabuku.
